Answer:

$y=25x$

Step-by-step explanation:

If Bella types 50 words in 2 minutes, we can divide 50 by 2 to see how many words she types in 1 minute.

$50/2=25$

So, Bella types 25 words per minute. When she first began writing her essay, she did not have words to start with, so there is no y-intercept ( $b$ ).

Therefore, the equation that represents this relation is $y=25x$ .

<u>Solving the equation</u>

We can divide 400 by 25 to determine how many minutes it would take her to finish her essay.

$\frac{400}{25} =16$

Therefore, it will take her 16 minutes to complete her essay.

Determine the number of possible triangles, ABC, that can be formed given angle A = 30°, a = 4, and b = 6.

Sophie [7]

Answer:

Step-by-step explanation:

Alright, lets get started.

using Sine Law,

$\frac{sinA}{a}=\frac{sinB}{b}$

$\frac{sin30}{4}=\frac{sinB}{6}$

$sinB=0.75$

$angle B = 48.6$

Another angle will be

$angle B' = 180-48.6 = 131.4$

considering angle B, angle C = $180 - (48.6+30)=101.4$

considering angle B', angle C' = $180-(131.4+30)=18.6$

$\frac{sinA}{a}=\frac{sinC}{c}$

$\frac{sin30}{4}=\frac{sin101.4}{c}$

$c = 7.84$

Similarly, finding c'

$\frac{sinA}{a}=\frac{sinC'}{c'}$

$\frac{sin30}{4}=\frac{sin18.6}{c'}$

$c'=2.55$

Hence two triangles are possible with below details: : Answer

A = 30, B = 48.6, C = 101.4, c = 7.84

A = 30, B' = 131.4, C' = 18.6, c' = 2.55

Hope it will help :)

Moving left subtracts from the x value the number you move.

In (2,9) the x value is the number 2

You move 1 unit to the left so subtract 1 from 2:

2-1 = 1

You will be at (1,9)

Find 3/7 of 21? Can you find this answer because my homework I do not know how to do so can you please find this question.

const2013 [10]

Answer:

Step-by-step explanation:

3/7 multiplied by 21 = 3/7 x 21 = 9 = 3/7 x 21/1 = 63/7 = 9

Or if you can't do the math - Think of a pizza with 21 slices . Now cut this pizza into 7 equal parts. You will find that each part contains exactly 3 slices. Now, eat 3 of these parts. With three slices in each part, you ate 9 slices - which is three sevenths of 21.

Answer:

4+2=6

15*6=90

9+9=18

18*3=54

90+54=144

Step-by-step explanation:

you have to add both the W and H together and then multiply them by the number of windows (4+2=6 , 16*6=90)

and the same with the garage doors (9+9=18, 18*3=54) then you take you two totals from multiplying and add them together (90+54=144)
