Answer:

27 1/8

Step-by-step explanation:

217/8= 27.125 = 27

217 - (8 x 27) = 1

We've now simplified 217/8 to a mixed number. To see it, we just need to put the whole number together with our new numerator and original denominator:

27 1/8

Simplifying our fraction

In this case, our fraction (1/8) can be simplified down further. In order to do that, we need to calculate the GCF (greatest common factor) of those two numbers. You can use our handy GCF calculator to work this out yourself if you want to. We already did that, and the GCF of 1 and 8 is 1.

1/1 = 1

8/1 = 8

When we put that together, we can see that our complete answer is:

27 1/8

My homework NEED HELP!

ziro4ka [17]

Answer:

the answer will be option A

Step-by-step explanation:

for the volume of a cube , we know,

(side)^3

so, here (2r)^3

= 8r^3

and the volume of a sphere is 4/3πr^3

so for a hemisphere it will be half., then 2/3πr^3

adding these two....we get

8r^3 + 2/3πr^3

= r^3(2/3π+8)

1.What is the slope of (0,2) and (-8,-8). What is the slope of (-8,-5) and (8,15)

ss7ja [257]

Answer:

Slope of (0,2) and (-8,-8): 5/4

Slope of (-8,-5) and (8,15): 5/4

Both slopes are 5/4

m = 5/4

Step-by-step explanation:

To find the slope:

1. Use the formula $m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$ .

2. Assign point 1 and point 2

3. State (x₁ , y₁) and (x₂, y₂)

4. Substitute x₁ , y₁, x₂, and y₂ into the formula

5. Solve

Slope of (0,2) and (-8,-8):

Point 1: (0,2) x₁ = 0 y₁ = 2

Point 2: (-8,-8) x₂ = -8 y₂ = -8

$m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$ Formula for slope

$m = \frac{-8-2}{-8-0}$ Substituted points

$m = \frac{-10}{-8}$ Simplified the subtraction then the negatives

$m = \frac{10}{8}$ Reduce fraction by dividing top and bottom by 2

$m = \frac{5}{4}$ First slope

Slope of (-8,-5) and (8,15):

Point 1: (-8,-5) x₁ = -8 y₁ = -5

Point 2: (8,15) x₂ = 8 y₂ = 15

$m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$ Formula for slope

$m = \frac{15-(-5)}{8-(-8)}$ Substituted points

$m = \frac{15+5}{8+8}$ Simplified the subtraction into addition

$m = \frac{20}{16}$ Reduce fraction (divide top and bottom by 4)

$m = \frac{5}{4}$ Second slope

Factor completely 10x^3+2x^2+5x+1

liubo4ka [24]

Answer:

$\boxed{\bold{\left(5x+1\right)\left(2x^2+1\right)}}$

Explanation:

Factor Out $\bold{2x^2}$ From $\bold{10x^3+2x^2: \ 2x^2\left(5x+1\right)}$

= $\bold{\left(5x+1\right)+2x^2\left(5x+1\right)}$

Factor Out Common Term 5x + 1

= $\bold{\left(5x+1\right)\left(2x^2+1\right)}$

$\bold{\italic{Mordancy}}$

Which pairs of polygons are congruent?

svetlana [45]

The <em><u>correct answer</u></em> is:

pairs 1 and 3

Explanation:

Congruent figures are the same size and the same shape.

Pair 1 has two polygons that are the same size and same shape; they are congruent.

Pair 2 has two polygons that are not the same size; the "stick" of the t shape of one figure is longer than the "stick" of the second figure.

Pair 3 has two polygons that are the same size and same shape; they are congruent.

Pair 4 has two polygons that are the same shape, but the first figure in green is larger than the second shape in red; this means they are not congruent.
