Answer:

So 60% of this unknown number is 28

Let this unknown number be n

60/100 × n = 28

0.60 × n = 28

n = 28/0.6

n = 46.7

To the nearest wholw number is 47

So there are 47 votes in total

The function h(t) = -4.9t² + 19.6t is used to model the height of an object projected in the air where h(t) is the height (in me

goblinko [34]

Answer:

Step-by-step explanation:

when h(t)=0

-4.9 t²+19.6t=0

4.9t(-t+4)=0

either t=0 or t=4

so domain is 0≤t≤4

for range

h(t)=-4.9t²+19.6t

=-4.9(t²-4t+4-4)

=-4.9(t-2)²+19.6

so range is 0≤h≤19.6

Which describes the cross section of a square prism that passes through vertices A, B, and C?

expeople1 [14]

Answer:

In triangle ABC one side equal $8\sqrt{2}$ and two sides equal $4\sqrt{13}$

Step-by-step explanation:

We are given a prism whose base is square with sides 8 in and height 12 in.

If we take cross section through vertices A, B and C

We will get a cross section as triangle.

In triangle ABC, sides are AB, BC and AC

AB is diagonal of top square whose side 8 in.

$AB=\sqrt{8^2+8^2}=8\sqrt{2}$

AC is face diagonal of front face.

$AC=\sqrt{8^2+12^2}=4\sqrt{13}$

BC is face diagonal of right face.

$BC=\sqrt{8^2+12^2}=4\sqrt{13}$

AC=BC≠AB

Hence, In triangle ABC one side equal $8\sqrt{2}$ and two side equal $4\sqrt{13}$

Step-by-step explanation:

a.8.50=2.50+1.20x

6.00=1.20x

5=x

5 loaves

b.20=2.50+1.20x

Write in slope-intercept form an equation of the line that passes through the given points. (-1, -1) (1, 5)

PSYCHO15rus [73]

<h2>Answer:</h2>

Step 1: We need to find the slope (or m) FIRST using slope formula*.

$m = \frac{5 - (-1)}{1 - (-1)}\\\\m = \frac{6}{2} = 3$

m = 3

Step 2: Now we find the y-intercept (or b) using the slope-intercept formula**, ONE of the 2 points given, and the slope we just found.

$5 = 3(1) + b\\\\5 = 3 + b\\\\2 = b$

b = 2

Step 3: Now we put it all together we get our equation in slope-intercept form**.

$y = 3x + 2$

**Slope-intercept form: $y = mx + b$

*Slope formula: $m = \frac{y_2 - y_1}{x_2 - x_1}$
