Determine the surface area of the square based pyramid. Round to the tenths place. 37 cm is the vertical height of the pyramid.
Answers
Answer:
SA= 3603.84cm^2
Step-by-step explanation:
the Surface Area SA is the total area of the sides and the base.
The area of the base= 32*32= 1024cm^2
the area of one of the sides = slant height of pyramid * base edge/2
the slant height l of the pyramid
l= sqrt(16^2+37^2) = 40.31cm
area of the side =( 40.31*32)/2 =644.96cm^2
there are 4 sides so the area of the sides are
4* 644.96=
addig the area of the base we get the Surface Area SA of the pyramid
SA = 2579.84 + 1024 = 3603.84cm^2

Answer:
the first one x is 6 and y is 11
the second one y is 5 and x is 3
the third one x is 15 and y is 17
the fourth one y is 15 and x is -12
Step-by-step explanation:
to find the first answer you have to use the actual equation given and substitute the value of x in it
y=-2(-6)/3+7
=12/3+7
=4+7
=11
the second one is quite different because the value of y has been given and not x so you have to substitute the value of y in the equation which is 5
5=-2x/3+7
5-7=-2x/3
-2/1=-2x/3
-2x/-2=-6/-2
x=3
for the third one you have to solve it like the first one
y=-2(15)/3+7
=10+7
=17
the fourth one is similar to the second one
15=-2x/3+7
15-7=2x/3
8=2x/3
-2x/-2=24/-2
x=-12

The jelly beans are all the same shape and size. Ryan does not like licorice or lime. What is the
probability that he will pick a jelly bean from the full box that has a flavor he does like? Show
and explain your work.
Answers
Answer:
24/60 does not like 36/60 does like
36/60 = .6 which is 60% chance
Step-by-step explanation:
The probability that Ryan will pick a jelly bean that has a flavor he likes is 0.7
What is probability?"Probability is a branch of mathematics which deals with finding out the likelihood of the occurrence of an event."
Formula of the probability of an event A is:[tex]P(A)=\frac{n(A)}{n(S)}[/tex]
where, [tex]n(A)[/tex] is the number of favorable outcomes
is [tex]n(S)[/tex] the total number of events in the sample space.
From given data:
Ryan received a box of jelly beans with
Grape - 16
Licorice - 10
Cherry - 12
Lemon - 14
Lime - 8
So, there are total 16 + 10 + 12 + 14 + 8 = 60 jelly beans.
Ryan does not like licorice or lime.
⇒ 10 + 8 = 18 jelly beans he does not like.
This means, he likes 60 - 18 = 42 jelly beans.
Now, we find the probability of jelly beans that has a flavor he likes.
⇒ P = (number of grape, cherry, lemon jelly beans) / (total number of jelly beans)
⇒ [tex]P=\frac{42}{60}[/tex]
⇒ [tex]\bold{0.7}[/tex]
Therefore, the probability that Ryan will pick a jelly bean from the full box that has a flavor he does like is 0.7

which of the following equations have complex roots?
Answers
9514 1404 393
Answer:
B. 3x² +2 = 0
Step-by-step explanation:
The equation of A has a couple of real roots. We're pretty sure there are complex numbers that will satisfy this equation, but we don't know how to find them. (We suspect a typo, and that the equation is supposed to be 2x² +1 = 7x, which has only real roots.)
__
The equation of B can be rewritten as ...
x² = -2/3
This will have complex roots.
__
The discriminants of both equations C and D are positive, so those have only real roots.

Find the value of x.

B. 9
C. 90
D. 11
ILL GIVE BRAINLIEST
Answers
Answer:
B) 9
Step-by-step explanation:
Because there's a square between the 2 angles, that means these angles are complementary (angles that add up to 90°). So:
5x - 9 + 6x = 90
11x - 9 = 90
11x = 90 + 9
11x = 99
x = 9
Answer:
B.9
Step-by-step explanation:
The way to solve this is by noticing that these angles are complementary(they add up to 90 degrees). So you add the equations together and equal them to 90. 5x-9+6x=90.Then you solve to find that x=9.

The square root of 0.25 is 0.5 which is a greater number. Give another number whose square root is larger than the number and explain why.
Answers
Answer:
Another example of a number who's square root is greater than the number is [tex]\sqrt{0.49}[/tex] which is 0.7
Step-by-step explanation:
This square root is larger than the number because it is a decimal. When you multiply a decimal by a decimal, the decimal point becomes greater. For example: 0.7 multiplied by 0.7 equals 0.49 which has 2 decimal places, while 0.7 only has one.

Find the discernment and the numbers of the number of real roots for this equation.
x^2+3x+8=0
Answers
Answer: 2 distinct complex solutions (ie non real solutions).
Work Shown:
The given equation is in the form ax^2+bx+c = 0, so
a = 1, b = 3, c = 8
Plug those into the formula below to find the discriminant
D = b^2 - 4ac
D = 3^2 - 4(1)(8)
D = -23
The discriminant is negative, so we get two nonreal solutions. The two solutions are complex numbers in the form a+bi, where a & b are real numbers and [tex]i = \sqrt{-1}[/tex]. The two solutions are different from one another.
Answer:
Discriminant: -23
Number of real roots: 0
Step-by-step explanation:
For a quadratic in standard form [tex]ax^2+bx+c[/tex], the discriminant is given by [tex]b^2-4ac[/tex].
In [tex]x^2+3x+8[/tex], assign:
[tex]a\implies 1[/tex] [tex]b\implies 3[/tex] [tex]c\implies 8[/tex]The discriminant is therefore:
[tex]3^2-4(1)(8)=9-32=\boxed{-23}[/tex]
For any quadratic:
If the discriminant is greater than 0, the quadratic has two real rootsIf the discriminant is equal to 0, the quadratic has one real rootIf the discriminant is less than 0, the quadratic as no real rootsSince the quadratic in the question has a discriminant less than 0, there are no real solutions to this quadratic.

Find the equation of the line passing through the point (-3.6, 2.1) and parallel
to the line 4.9x + 5.4y = 3
Answers
Answer:
y = -4.9/5.4x - 1.17
Step-by-step explanation:
First let's convert the equation to standard form of y = mx + b.
4.9x + 5.4y = 3
Subtract 4.9x from both sides.
5.4y = -4.9x + 3
Divide each term by 5.4.
y = -4.9/5.4x + 0.56
If two lines are parallel to each other, they have the same slope slopes.
The first line is y = -4.9/5.4x + 0.56. Its slope is -4.9/5.4. A line parallel/perpendicular to this one will also have a slope of -4.9/5.4.
Plug this value (-4.9/5.4) into your standard point-slope equation of y = mx + b.
y = -4.9/5.4x + b
To find b, we want to plug in a value that we know is on this line: in this case, it is (-3.6, 2.1). Plug in the x and y values into the x and y of the standard equation.
2.1 = -4.9/5.4(-3.6) + b
To find b, multiply the slope and the input of x (-3.6)
2.1 = 3.27 + b
Now, subtract 3.27 from both sides to isolate b.
-1.17 = b
Plug this into your standard equation.
y = -4.9/5.4x - 1.17
This equation is parallel/perpendicular to your given equation (y = -4.9/5.4x + 0.56) and contains point (-3.6, 2.1)

Sabina bought a samsung mobile set for rs.15750 after getting the discount of 10%. Find the price of mobile set before discount.
Answers
Answer:
Step-by-step explanation:
90/100 * x = 15750
0.9 x = 15750
x = 15750/0.9
x = 17500
Now check this by taking 10% off. Do you get 15750?
Let's see
10/100 of 17500 = 1750
Subtract that from 17500
17500 - 1750 = 15750 which is exactly what you should get.
