Answer: 6

Step-by-step explanation:

By tallying up the x's in total in 3/8 and 1/2, it would be 6.

Answer:

A' = 3A

Step-by-step explanation:

The area of a triangle is given by :

[tex]A=\dfrac{1}{2}\times b\times h[/tex]

Where

b is base and h is height

If height is tripled, h' = 3h

New area,

[tex]A'=\dfrac{1}{2}\times b\times h'\\\\=\dfrac{1}{2}\times b\times 3h\\\\=3\times \dfrac{1}{2}\times b\times h\\\\=3A[/tex]

So, the new area becomes 3 times the initial area.

Answer:

x = 8

Step-by-step explanation:

The measures of the angles in a triangle add up to equal 180°

That being said we can create an equation to solve for x

( note that this is a right triangle indicated by the square. A right triangle has a right angle which has a measure of 90° )

180 = 90 + 5x + 5 + 5x + 5

now we solve for x using basic algebra

step 1 combine like terms

90 + 5 + 5 = 100

5x + 5x = 10

now we have 180 = 100 + 10x

step 2 subtract 100 from each side

180 - 100 = 80

100 - 100 cancels out

now we have 10x = 80

step 3 divide each side by 10

10x / 10 = x

80 / 10 = 8

we're left with x = 8

Answer: 10

She cant be the same age as him or older because hes 3/2 older

p ² + 6 is even if p ² is even (the sum of two even numbers is even), and this happens only if p itself is even, i.e. if p = 2 since 2 is the only even prime.

All other primes p are odd, so p ² would be odd, and adding 6 would not change that (odd + even = odd).

The volume of a cylinder can be found with the following equation

[tex]V = r^2h\pi[/tex]

After inputting the known information we get

[tex]980\pi = r^220\pi \\\\[/tex]

Which simplifies to

radius = 7 or (-7)

For proof's sake, we can try the equation again with the known radius

[tex]980\pi = r^220\pi \\980\pi = (7^2)20\pi \\980\pi = (49)20\pi \\980\pi = 980\pi \\[/tex]

And because the radius is being squared, it can either be negative or positive.

Answer:

C

Step-by-step explanation:

Answer:

No, Jeremy can not find the cost of the sneakers by adding the percents, you have to math one sale discount at a time.

The answer is $45.90.

Step-by-step explanation:

You have to multiply $60 by 15%, getting $9. Subtract 9 from 60 and get the first discount price: $51. Then you will multiply 51 by `10% and get 5.1, subtract 5.1 from 51 and get your final sale price of $45.90. If you added the percents together you would get an incorrect value of $45. Close but not the correct answer.

Sa Of Rectangular Prism - 65

Sa Of Pyramid - 85

TOTAL SURFACE AREA - 150

Answer:

26 square units

Step-by-step explanation:

We are given a diagram and are asked to find the area of the figure in square units.

To solve, take in mind that we need to multiply the sides given.

Area is L * W, therefore, we know that our length is 5 by 2 units, while our width is 3 by 2 units.

First start with the length, since it is 5 by 2 we multiply 5 and 2 :

5 * 2 = 10

Then with the width, since it is 3 by 2, we can multiply 3 and 2 :

3 * 2 = 6

Then do the length again since the bottom part of the diagram needs to be included, it is also 5 by 2 :

5 * 2 = 10

Add all these together to get your answer :

10 + 6 + 10

16 + 10

26 square units.

Answer: 30 meters

Step-by-step explanation:

Volume of a cylinder = πr^2h

2,827.43 = πr^2(4)

2,827.43 = 3.14(4)r^2

2,827.43 = 12.56*r^2

2,827.43/12.56 = (12.56*r^2)/12.56

225.11 = r^2, find square root of both sides

r = 15

diameter = 30

Answer:

72.5 km/h

Step-by-step explanation:

Multiply the km/h by how many hours your going at that speed/total number of hours on trip.

(90x(3.5/8))+(80x(2/8))+(70x(1.5/8))

39.375+20.5+13.125

Answer:

756

Step-by-step explanation:

478 + 278 = 756

Answer:678 Gummies

Step-by-step explanation:
