Answer:
34?
Step-by-step explanation:
I think 34 because 3×3 is equal to 9. 5×5 is equal to 25. If you add 9+25, you would get 34.
Answer:
24 cm²
Step-by-step explanation:
the area = ½× (3+3) × (5+3)
= ½× 6×8
= 3×8
= 24 cm²
Does the graph of the straight line with slope of -3 and y-intercept of -4 pass through the point (-2, 2)?
Answer:
abcdefghijklmnopqrstuvwxyz
Answer:
yes
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 3 and c = - 4 , then
y = - 3x - 4 ← is the equation of the line
To determine if (- 2, 2) lies on the line, substitute x = - 2 into the equation and if y equals 2 then the point lies on the line.
y = - 3(- 2) - 4 = 6 - 4 = 2 ← true
Then the line passes through (- 2, 2 )

Given:
a. 35% of 150 g
b. 113% of $55
To find:
The correct values for the given blanks.
Solution:
a. 35% of 150 g
Here, the percent part is 35% and percent whole is 100%.
35% of 150 g is:
[tex]\dfrac{35}{100}\times 150=52.5[/tex]
So, the number part is 52.5 g and the whole number is 150 g.
Therefore, the percent part is 35%, number part is 52.5 g and the whole number is 150 g.
b. 113% of $55 g
Here, the percent part is 113% and percent whole is 100%.
113% of $55 is:
[tex]\dfrac{113}{100}\times 55=62.15[/tex]
So, the number part is $62.15 and the whole number is $55.
Therefore, the percent part is 113%, number part is $62.15 and the whole number is $55.

If the angles are proportional to 3, 4, 5,Then the angle measures are 3x, 4X and 5X
Step-by-step explanation:
Answer:
45 60 75
Step-by-step explanation:
Let's call the angles 3 x , 4 x and 5 x
They must add up to 180 o in a triangle, so:
3 x + 4 x + 5 x = 12 x = 180 → x = 180 / 12 = 15 So the angles are:
3 ⋅ 15 = 45 o 4 ⋅ 15 = 60 o 5 ⋅ 15 = 75 o Check answer:
45 + 60 + 75 = 180

A 15 foot pole extends t feet below ground and 10 feet above ground. Choose the linear equation that models the situation.
No options are given for the question :
Answer:
t + 10 = 15
Step-by-step explanation:
Given that :
Length of pole = 15 feet
Height below the ground = t
Height above the ground = 10
Tge linear equation which represents the scenario can be modeled as :
Entire length of pole = 15 feets
Length above ground = 10
Length below ground = t
Length below + length above = total length
t + 10 = 15
Find the integer that lies between [tex]$\sqrt[3]{-45}$ and $\sqrt[3]{-101}$[/tex]
∛(-45) = ∛((-1) × 45) = ∛(-1) × ∛45 = -∛45
Similarly,
∛(-101) = - ∛101
Now,
• 3³ = 27 and 4³ = 64, and 27 < 46 < 64, so ∛27 < ∛45 < ∛64, which places ∛45 between 3 and 4
• 5³ = 125, so ∛101 would similarly fall between 4 and 5
So to summarize, we have
3 < ∛45 < 4 < ∛101 < 5
so that
-5 < ∛(-45) < -4 < ∛(-101) < -3
so the integer between these numbers is -4.

Lorraine computed a confidence interval for µ based on a sample of size 41. Since she did not know σ, she used s in her calculations. Lorraine used the normal distribution for the confidence interval instead of a Student's t distribution. Will her interval be longer or shorter than one obtained by using an appropriate Student's t distribution? Explain.
Answer:
Shorter
Step-by-step explanation:
When given the population standard deviation, σ, the normal distribution should be used. However, if the sample standard deviation is being used, the t distribution should be used. The implication of using a normal distribution in Lorraine's case when using the sample standard deviation which requires the use of the T - distribution is that, the interval beacjbea smaller as the critical value obtained is smaller than the T critical value with degree of freedom, n - 1 ; 41 - 1 = 40
At α = 0.05 ;
Tcritical, df = 40 = 2.02
Zcritical = 1.96

x² -23n +132 pls help
Answer:
(x-11)(x-12)
Step-by-step explanation:
To clarify, there was a likely typo written in your question since it is impossible to solve two unknown values with only one equation. I'm supposing that the equation was supposed to be
[tex] {x}^{2} - 23x + 132[/tex]
The first step is to split the term into factorable terms.
Since the highest power is power of 2, the equation would look like this if factorized:
[tex](ax + b)(cx + d)[/tex]
If the terms were added properly, the expanded equation would be:
[tex](ac \times {x}^{2} ) +( (ad + bc) \times x) + (bd)[/tex]
Generally, we do not see decimal values or fractions in factorization with some exceptions. Otherwise, the equation could get very complicated.
In this case, we can determine the following:
[tex]a \times c = 1[/tex]
[tex](a \times d) + (b \times c) = - 23[/tex]
[tex]b \times d = 132[/tex]
First, we can determine a and c to be one since one only has one factor, which is itself.
This leaves us with two equations left
[tex]b + d = - 23[/tex]
[tex]b \times d = 132[/tex]
There are two ways to solve the remaining two terms. We can either find the factors or do quadratic equation. Finding the factors is the easier way out here.
b and d will add up to negative values but multiplying these values give positive values. The most likely reason is that b and d are negative values.
Now, we can find the factors of 132.
The factors are 1, 2, 3, 4 , 6, 11, 12, 22, 33, 44, 66 and 132. However, the values flip around.
In fact, the "factors" we are looking for are the negative values of the actual factors. To solve this, we should find two factors that add up to 23.
In this case, 11+12=23.
To verify, 11*12 is also 132.
Since we are looking for the negative values, the values we are looking for are -11 and -12.
The values can be plugged in anywhere in b or d.
After cleaning up, we can plug in the values into our factorization and we will get:
[tex](1x - 11)(1x - 12)[/tex]
or
[tex](x - 11)(x - 12)[/tex]
A bus leaves Riverside for Springfield and averages only 48 mph. Ten minutes later Smith leaves Riverside for Springfield traveling 64 mph in his car. How long before he overtakes the bus?
Answer:
pls give brainliest even if u dont want to. it will make u better person. when u give brainliest it makes u 3 times smarter
Step-by-step explanation:
Smith overtakes the bus at (2/3)×60=40 minutes
What is speed?
A body is said to have speed v if he travels v distance in unit time.
How to solve it?Suppose that Smith overtakes the bus at a time 't'. Then the distance traveled by bus is 48×t m and that by Smith is 64×(t-1/6).
Smith needs t-1/6 hours to reach the same position that the bus is in.
Since Smith leaves ten minutes later hence it takes t-1/6 hours for him to overtake the bus.
Because 10 minutes is equal to 10/60=1/6 hour.
So,
48×t=64×(t-1/6)
⇒t=2/3
Hence, Smith overtakes the bus at (2/3)×60=40 minutes

“If f(x) = x^2 + 7, find f(x+2)”
Answer:
=x^2 +4x+11
Step-by-step explanation:
f(x) = x^2 + 7,
Replace x with x+2
f(x+2) = (x+2)^2 + 7
= (x+2)(x+2) +7
FOIL
= x^2 +2x+2x+4 +7
Combine like terms
=x^2 +4x+11
Answer:
[tex]f(x+2)=x^2+4x+11[/tex]
Step-by-step explanation:
In [tex]f(x)=x^2+7[/tex], for all values of [tex]x[/tex], we substitute [tex]x[/tex] (what is in the parentheses) into [tex]x^2+7[/tex] to output a [tex]y[/tex] value.
In [tex]f(x+2)[/tex], the term [tex](x+2)[/tex] is in the parentheses. Therefore, substitute [tex](x+2)[/tex] for [tex]x[/tex] in [tex]x^2+7[/tex] to find [tex]f(x+2)[/tex]:
[tex]f(x+2)=(x+2)^2+7[/tex]
Expand using [tex](a+b)^2=a^2+2ab+b^2[/tex],
[tex]f(x+2)=x^2+4x+4+7[/tex]
Combine like terms:
[tex]\boxed{f(x+2)=x^2+4x+11}[/tex]

At her gym, Ximena spends 30 minutes on each aerobic workout and 20 minutes on each weight-lifting workout. Last week, Ximena spent between 190 and 230 minutes, inclusive, on 3 aerobic
workouts and w weight-lifting workouts. What is
one possible value of w?
Answer:
The possible values of W are 5, 6, and 7.
Step-by-step explanation:
Since at her gym, Ximena spends 30 minutes on each aerobic workout and 20 minutes on each weight-lifting workout, and last week, Ximena spent between 190 and 230 minutes, inclusive, on 3 aerobics workouts and W weight-lifting workouts, to determine what is one possible value of W the following calculation must be performed:
190 - (3 x 30) = X
190 - 90 = X
100 = X
100/2 = 5
140/2 = 7
Therefore, the possible values of W are 5, 6, and 7.
which relation is a function?
The first one because there is only one y value for every x value. The correct option is first.
To determine if a relation is a function, use the vertical line test: If any vertical line intersects the graph of the relation at more than one point, then the relation is not a function. On the other hand, if every vertical line intersects the graph of the relation at most once, then the relation is a function.
In first relation is considered a function, because each input x-value is associated with exactly one output y-value. In other words, for every x-value in the domain of the relation, there can be only one corresponding y-value in the range. Each x-value should not have more than one y-value associated with it.
Therefore, each x-value should not have more than one y-value associated with it. The correct option is first.

An absolute value graph looks like a V. If the number attached to the x is positive, then the graph opens upwards. If the number attached to the x is negative, then the graph opens downwards.
In this case, the graph opens downwards.
To find the vertex, look at the |x - 1| part of the equation. This tells us that x is shifted 1 to the right (opposite of the sign). And, the 3 outside of the absolute value bars tells us that the graph is also shifted up 3. Therefore, the vertex is (1, 3).
Next, we need to figure out how to graph it. That's where the -2 in front comes in. We know the graph faces downwards already. So, from the vertex, we will go down 2 spaces and left or right 1 depending on the side you are working on. Continue this pattern just like you would graphing the slope of a regular line, but this one is two sided.
If you need to view the graph for further help, I would recommend an online graphing calculator such as Desmos.
Hope this helps!
