Answer:
2 and 5 is the gcf and lcm is 360
Step-by-step explanation:
Answer:
GCF is 120 and LCM is 1440
Step-by-step explanation:
-To find the GCF, take a look at the orange section(the intersection) and multiply all the numbers in there. 2^3x3x5=120
-To find the LCM, multiply all the numbers in the entire venn diagram. 2^5x3^2x5=1440

6) 82°F to °C = ___________
7) 104°C to F =____________
8) 68°F to C = ____________
9) 47°C to F =_____________
Answer:
6 ≈ 27.78C
7 = 219.2F
8 = 20C
9 = 116.6F
Step-by-step explanation:
6. From the formula C/5 = (F-32)/9
We get C/5 = (82-32)/9
C = (50/9)*5
C ≈ 27.78
7. From the formula C/5 = (F-32)/9
We get 104/5 = (F-32)/9
F-32 = 104/5 * 9
F-32 = 187.2
F = 219.2
8. From the formula C/5 = (F-32)/9
We get C/5 = (68-32)/9
C/5 = 36/9
C/5 = 4
C = 5 * 4
C = 20
9. From the formula C/5 = (F-32)/9
We get C/5 = (F-32)/9
47/5 = (F-32)/9
(47/5)*9 = (F-32)
84.6 = F-32
F = 84.6 + 32
F = 116.6

Formula
(104°C × 9/5) + 32 =219.2°F
104°C =219.2°F
8) 68°F to C°
Formula
(68°F − 32) × 5/9 = 20°C
68°F=20°C
9) 47°C to °F
Formula
(47°C × 9/5) + 32 = 116.6°F
47°C =116.6°F

Heidi solved the equation
3(x + 4) + 2 = 2 + 5(x – 4). Her steps are below:
3x + 12 + 2 = 2 + 5x – 20
3x + 14 = 5x – 18
14 = 2x – 18
32 = 2x
16 = x
Answer:
The answer is correct
Step-by-step explanation:
3(x + 4) + 2 = 2 + 5(x – 4)
3x + 12 + 2 = 2 + 5x - 20
3x + 14 = 5x - 18

Amy flips a coin and rolls a standard number cube. Find the probability that the coin will show heads and the cube will show one.
Write the probability as a fraction in the simplest form.
Answer:
1/12
Step-by-step explanation:
Mathematically, when a coin is flipped, we either get a head or a tail
These are equal probabilities of 1/2 each
So to show heads, we have a probability of 1/2
In a standard cube, there are 6 numbers (1-6)
now, we have only 1 one
the probability of it showing up would be 1/6
So the probability of both occurring would be the product
So we have this as;
1/6 * 1/2 = 1/12

Jane spent 3 hours exploring a mountain with a dirt bike. First, she rode 48 miles uphill. After she reached the peak she rode for 15 miles along the summit. While going uphill, she went 5 mph slower than when she was on the summit. What was her rate along the summit?
Answer: [tex]25\ mph[/tex]
Step-by-step explanation:
Given
Jane took 3 hours
First she rode 48 miles with let say with [tex]x[/tex] mph
then she rode 15 miles with speed [tex](x+5)[/tex] mph
Equate the time in each ride and equate it to total time
[tex]\Rightarrow 3=\dfrac{48}{x}+\dfrac{15}{x+5}\\\\\Rightarrow 3x(x+5)=48(x+5)+15x\\\\\Rightarrow 3x^2+15x=48x+48\times 5+15x\\\\\Rightarrow 3x^2-48x-240=0\\\\\Rightarrow (x-20)(x+4)=0\\\\\text{Neglecting the negative value as speed cannot be negative}\\\\\Rightarrow x=20\ mph[/tex]
So, her along the summit is [tex]x+5=25\ mph[/tex]
find the measure of the missing side in the right triangle
Answer:
[tex]12.2\text{ ft}[/tex]
Step-by-step explanation:
In any right triangles, the Pythagorean Theorem states that the sum of the squares of both legs is equal to the hypotenuse squared ([tex]a^2+b^2=c^2[/tex], where [tex]c[/tex] is the hypotenuse, or longest side).
In this case, the length we're solving for is the hypotenuse of the triangle and the two legs of the triangle are 7 and 10. Therefore, we have:
[tex]7^2+10^2=c^2,\\49+100=c^2,\\c^2=149,\\c=\sqrt{149},\\c\approx \boxed{12.2\text{ ft}}[/tex]

Write the equation of a function whose parent function, f(x) = x + 5, is shifted 3 units to the right.
Answer:
B . g(x) = x + 8
Step-by-step explanation:
Write the equation of a function whose parent function, f(x) = x + 5, is shifted 3 units to the right.
g(x) = x + 3
g(x) = x + 8
g(x) = x − 8

+vt+c. A soccer ball is kicked with a starting upward velocity of 50 ft/s from a starting height of 3.5 ft. Substitute the values into the vertical motion formula Let h = 0.
Explanation
Step 1
1 of 2
The starting velocity is 50 ft/s ,when the ball is 3.5 ft high
So, v=50v=50 , h=3.5h=3.5 , t=0t=0
\begin{align*} h&=-16t^2+vt+c &&\text{{\color{#c34632}The vertical motion formula}}\\\\ 3.5&=-16(0)^2+50(0)+c &&\text{{\color{#c34632}Substitute 3.5 for $h$ , 50 for $v$ , 0 for $t$}}\\\\ c&=3.5 &&\text{{\color{#c34632}Simplify}}\\\\ \end{align*}
h
3.5
c
=−16t
2
+vt+c
=−16(0)
2
+50(0)+c
=3.5
The vertical motion formula
Substitute 3.5 for h , 50 for v , 0 for t
Simplify
So, the vertical motion formula will be
h= -16t^2 + 50t + 3.5
Let h= 0
-16t^2 + 50t + 3.5= 0

We also know that <DMA = < TMU
Two sides and the included angle
We can use SAS to show that the triangles are congruent
Answer
DM = MT (sides)
AM =MU ( sides)
<DMA = < TMU ( Angles)
So, DMA triangle is congruent to TMU triangle

Ella has two 8ft long boards she needs to cut pieces that are 15 inches long how many 15 inch pieces can she cut the two boards
Answer:
12
Step-by-step explanation:
Ella has two 8 feet long boards, so in total, she has 16 feet of the boards.
Convert these 16 feet to inches. There are 12 inches in a foot, so multiply 16 by 12:
16(12)
= 192
So, there are 192 inches in the boards. Divide this by 15 to see how many 15 inch pieces she can cut:
192/15
= 12.8
We can only have a whole number answer, because the boards need to be a full 15 inches. So, round this down:
= 12
Ella can cut twelve 15 inch pieces.
Brittany and Natalie, start cycling together from their home to school, which is 14.4 miles away. Natalie takes 40 minutes to reach school and Brittany reaches 20 minutes after Natalie.
How much faster is Natalie (in mph)?
The result shows that Brittany is faster than Natalie because she moved faster than her. Therefore, Brittany is (43.64 - 21.5) = 22.14mph faster than Natalie.
How to calculate average speed?The average speed can be calculated by dividing the distance moved by the time taken. That is;
Average speed = Distance/time
According to this question, Brittany and Natalie start cycling together from their home to school, which is 14.4 miles away.
However, Natalie takes 40 minutes to reach school and Brittany reaches 20 minutes after Natalie.
First, we calculate the average speed of each individual as follows:
Natalie = 14.4miles ÷ 0.67hrs = 21.5mphBrittany = 14.4miles ÷ 0.33hrs = 43.64mphThis shows that Brittany is faster than Natalie because she moved faster than her. Therefore, Brittany is (43.64 - 21.5) = 22.14mph.

Answer 16
Step-by-step explanation:
An automobile traveled 7 hours at an average
speed of 50 miles per hour. It averaged only 40
miles per hour on the return trip. The average
speed per hour, to the NEAREST mile, for the
round trip was
(A)46 miles per hour
(B) 44 miles per hour
(C)43 miles per hour
(D) 47 miles per hour
Answer:
(B) 44 miles per hour
Step-by-step explanation:
We are given that
Speed, v1=50 miles/hr
Time, t1=7 hours
Average speed, v2=40 miles/hr
We have to find the average speed per hour for the round trip .
Distance traveled by automobile from one side
d1=[tex]v_1t=50\times 7=350[/tex]miles
d1=d2=350 miles
Total distance=d1+d2=350+350=700 miles
Now,
[tex]t2=\frac{d_2}{v_2}=\frac{350}{40}=8.75 hour[/tex]
Total time=t1+t2=7+8.75=15.75 hours
Now, average speed for the round tripe
=[tex]\frac{total\;distance}{total\;time}[/tex]
=[tex]\frac{700}{15.75}=44.4\approx 44[/tex]miles/hr
Hence, option (B) is correct.

Answer:
a) (1.75 +1.00d)/4 < (3.50 +1.50d)/5
b) 3.70
Step-by-step explanation:
a) You want ...
classic cost < XL cost
Using the given expressions for the costs, the inequality is ...
(1.75 +1.00d)/4 < (3.50 +1.50d)/5
__
b) For a 10-mile ride, the XL cost is ...
(3.50 +1.50(10))/5 = (3.50 +15.00)/5 = 18.50/5 = 3.70
Each passenger in a group of 5 friends pays $3.70 for the 10-mile ride.
_____
Additional comment
Each expression can be divided out to give ...
classic cost per person = $0.4375 +0.25d
XL cost per person = $0.70 +0.30d
Comparing these, we see there is no positive value of d that will make the XL cost per person be less than the classic cost per person. Both the initial fee and the per-mile cost are lower for the classic.
