Answer: 5/4

Step-by-step explanation:

To get the number of groups of 4/5 are in 1, we divide 1 by 4/5. This will give:

= 1 ÷ 4/5

= 1 × 5/4

= 5/4

<h3>There are 5/4 groups of 4/5 in 1.</h3>

Write the equation -3x + 4y = 16 in slope-intercept form.

Vlad1618 [11]

Answer:

y = $\frac{3}{4}$ x + 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

- 3x + 4y = 16 ( add 3x to both sides )

4y = 3x + 16 ( divide all terms by 4 )

y = $\frac{3}{4}$ x + 4 ← in slope- intercept form

-5^2 + (-15) ÷ (-3) + 20 Solve using PEMDAS showing work

oee [108]

In PEMDAS, there is no parentheses in this equation, so we move on to exponents.

-5^2 is 25
Now, we divide -15/-3 then we get 5
Next, we do -3+20=17
25+5+17 would be 47

Your answer should be 47!
Hope this helps (:

Hasan is painting a spherical model of a human cell for his science class. He uses 100π square inches of paint (in one coat) to

babymother [125]

Answer:

10 in

Step-by-step explanation:

So we want to consider the surface area of this sphere.

The formula for surface area of a sphere is $A=4 \pi r^2$ .

So we have that the surface area is $100 \pi$ .

So I'm going to replace $A$ in $A=4 \pi r^2$ with $100 \pi$ .

$100\pi=4\pi r^2$

Now our main objective here is to solve for $r$ :

Divide both sides by $4 \pi$ :

$\frac{100\pi}{4 \pi}=\frac{4\pi r^2}{4 \pi}$

This gets us $r^2$ by itself:

$25=r^2$

What number squared gives you 25? If you don't know, just take the square root of both sides giving you:

$\sqrt{25}=r$

Now you can just put $\sqrt{25}$ in your calculator. You should get 5.

5 is the radius

The diameter is twice the radius.

So 2(5) is 10, so the diameter is 10 in.

Find the midpoint of BF B(0,-14) F(4,6)

saveliy_v [14]

Answer:

Step-by-step explanation:

B(0, -14) ⇒ x₁ = 0 & y₁ = -14

F(4,6) ⇒ x₂ = 4 & y₂ = 6

$Midpoint = \left(\dfrac{x_{1}+x_{2}}{2}, \dfrac{y_{1}+y_{2}}{2} \right)$

$=\left(\dfrac{0+4}{2},\dfrac{-14 + 6}{2}\right)\\\\\\= \left(\dfrac{4}{2}, \dfrac{-8}{2} \right)\\\\\\=\left(2, -4 \right)$
