–6x − 8y = –14
y = –2

Answers

Answer:

x = 5

Step-by-step explanation:

If you input the y-value into the equation you get x = 5.

-6x-8(-2) = -14

-6x+16 = -14

-6x+16-16 = -14-16

-6x = -30

(-6x)/-6 = (-30)/-6

x = 5

what is the approximate radius of the bowl shown that is shaped as a hemisphere

Answers

Answer:

Approximate radius of the given hemisphere is 3 in.

Step-by-step explanation:

Formula to calculate the volume of a hemisphere is given by,

V = [tex]\frac{2}{3}\pi r^{3}[/tex]

Since, volume of the given hemisphere in the picture = 56.52 in²

By substituting the value of V in the formula,

56.52 = [tex]\frac{2}{3}\pi r^{3}[/tex]

Now solve the expression for the value of 'r',

r³ = [tex]\frac{3}{2\pi }(56.52)[/tex]

r³ = 26.99

r = ∛(26.99)

r = 3 in.

Therefore, approximate radius of the given hemisphere is 3 in.

Multiplying by 0.05 is the same as decreasing by _____%.

Answers

Answer:

95%

Step-by-step explanation:

When a value is multiplied by 0.05 ;

The equivalent percentage decrease on the value is :

(1 - 0.05) * 100%

0.95 * 100%

= 95%

Therefore, Multiplying a value by 0.05 is the same as decreasing by 95%

is 15m 36m 39m right triangle

Answers

Answer is below. Look at my explanation to understand my answer.

To see if these lengths can make a triangle, we can use the "triangle side theorem."

The formula is:

a + b > c

a + c > b

b + c > a

So, with that being said...

15 → A

36 → B

39 → C

So, we can use the triangle side theorem by adding A & B, A & C, and B & C.

If the side length is greater than C, B, or A, it can make a triangle. But if it isn't greater than C, B, or A, it cannot make a triangle.

So, let's add 15 and 36 to see if it can make a triangle.

15 + 36 = 51

If you read above, C is 39.

So, 51 > 39

15 + 36 > 39 ✓

Let's repeat this process again.

Instead of C, B is what we're now seeing if the sum is greater than it.

15 + 39 = 54

54 is greater than 36...

54 > 36

So it is true.

15 + 39 > 36 ✓

Now, A is what we're seeing if the sum is greater than it.

36 + 39 = 75

75 is greater than 15...

75 > 15

So it is true.

36 + 39 > 15 ✓

So yes, these lengths can make a triangle.

Answers

Answer:

It will take 1 hour and 25 minutes to pack the 40 hampers

Step-by-step explanation:

Julie can pack 18 hampers in 5 hours

Kyle can pack 14 hampers in 4 hours

Julie and Kyle work together to pack a total of 40 hampers

Work done by Julie in one hour = 18/5

Work done by Kyle = 14/4

Work done all together

14/4 * 4 + 18/5 *5 = 40 * 1/x

14+18/40 = 1/k

K = 40/32 = 1.25 hours

Answers

Answer:

Answer A.

Step-by-step explanation:

There is a 1/2 chance of getting either heads or tails on a coin since there are only two sides. That means that half of the pairs should contain H and half should contain T.

There is a 1/6 chance of rolling every number on a die. So this needs to be represented with the numbers 1-6 on every pair.

So if we combine both of those, 1-6 being on every pair and H being on half and T being on the other half, we get

1, H

2, H

3, H

4, H

5, H

6, H

1, T

2, T

3, T

4, T

5, T

6, T

Which is answer A.

Find the volume of the composite solid.

Answers

Here's the solution,

the volume of the given figure is :

=》

[tex]volume \: \: of \: \: (pyramid \: + rectangular \: \: prism)[/tex]

volume of pyramid :

=》

[tex] \dfrac{l \times b \times h}{3} [/tex]

=》

[tex] \dfrac{4 \times 5 \times 6}{3} [/tex]

=》

[tex] \dfrac{120}{3} [/tex]

=》

[tex]40[/tex]

volume of pyramid = 40 cm³

now, volume of rectangular prism :

=》

[tex]l \times b \times h[/tex]

=》

[tex]4 \times 5 \times 2[/tex]

=》

[tex]40[/tex]

volume of rectangular prism = 40 cm³

volume of composite figure = 40 + 40

=》80 cm³

The volume of the composite solid will be 80 cubic cm.

What is Geometry?

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

Let the prism with a length of L, a width of W, and a height of H. Then the volume of the prism is given as

V = L x W x H

The volume of the Pyramid will be given as,

V = (1/3) × Base area × height

Then the volume of the geometry will be

V = L x W x H + (1/3) x Base area x height

V = 5 x 4 x 2 + (1/3) x 4 x 5 x 6

V = 40 + 40

V = 80 cubic cm

Thus, the volume of the composite solid will be 80 cubic cm.

Answer:

70

Step-by-step explanation:

the formula for area of a trapezoid is (a+b)/2*h, where a and b each equal a base and h represents height. the base measurements of this figure are 9 and 11, and the height is 7 inches. in the formula, that is (9+11)/2*7. first, 9+11 is 20, divided by 2 is 10. 10*7=70, so the area is 70 in^2.

the volume of a cube is 710 cm cubed work out the length of its side rounded to one decimal place​

Answers

Answer:

8.9cm

Step-by-step explanation:

Volume of a cube = L × L × L = L³

710 = L³

L = ³√710

L= 8.9 cm

The length of each side of Cube is 8.9 cm.

What is Volume of Cube?

The length is to be multiplied by itself three times to get the volume. The volume is measured in cubic units.

For example, cubic units.

Given:

Volume of a cube is 710 cm.

So, Volume of Cube = l³

710 = l³

l = ∛710

l = ∛ (71 x 10
