It will take 30 minutes to type the proposal when working together.

Step-by-step explanation:

Given that Gina types a proposal in 90 minutes.The other person types a proposal in 45 minutes. If working together then you can calculate as follows;

In 1 minute, Gina types 1/90 of the proposal

In 1 minute, the other person types 1/45 of the proposal

When working together, they write 1/90+1/45 =3/90 of the proposal in 1 minute

So it will take 90/3 minutes to write the proposal when working together.

90/3 minutes = 30 minutes

7. The points P(2, -3), Q(3, -2) and R(8, z) are

Hatshy [7]

Answer:

z = 3

Step-by-step explanation:

Since the points are collinear then the slopes between the points are equal.

Calculate the slope m using the slope formula

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

with (x₁, y₁ ) = P (2, - 3) and (x₂, y₂ ) = Q (3, - 2)

m = $\frac{-2+3}{3-2}$ = 1

Repeat with

(x₁, y₁ ) = Q (3, - 2) and (x₂, y₂ ) = R (8, z )

m = $\frac{z+2}{8-3}$ = $\frac{z+2}{5}$ , then

$\frac{z+2}{5}$ = 1 ( multiply both sides by 5 )

z + 2 = 5 ( subtract 2 from both sides )

z = 3

A pretzel maker was interested in knowing the number of pretzels in each bag is sold. The results of the research are shown in t

Vladimir [108]

Answer:

23 pretzels

Step-by-step explanation:

The range value is obtained by taken the difference between the maximum and minimum values ;

The range = maximum - minimum

From the box and whisker plot attached ; the maximum value = 68

Minimum value = 45

Hence, the range in the number of pretzels :

68 - 45 = 23

What is the measure of ∠x?

Dima020 [189]

The angle is a complementary angle so both angles add up to 90 degrees

Therefore set your equation equal to 90 to find angle of x

53+x=90

Subtract 53 from both sides

X= 37 degrees
