In a parallelogram, adjacent angles sum to 180. Since the labeled angle is adjacent to the 124° angle, we have

$2z+16 +124 = 180 \iff 2z = 180-124-16 \iff 2z= 40 \iff z = 20$

Jill got an 85% on a math test if there were 40 questions in total,how many did she get wrong?

GrogVix [38]

You can solve this by setting up a proportion. You can put the number of items correct over the total number. and substitute the unknown number with x.

$\frac{85}{100}$ = $\frac{x}{40}$ Cross-multiply
3400 = 100x Divide both sides by 100
34 = x

40 - 34 = 6

So, Jill got 6 questions wrong.

Answer:

Hence first graph is the correct answer.

T I

1 28

2 56

3 84

4 112

Step-by-step explanation:

Given that initial amount P = $400

Simple rate of interest = R = 7% = 0.07

Time t= 1,2,3,4 years.

Then apply Simple interest formula to find the total interest earned in the given years.

I=PRT

for t=1 year

I=PRT=400(0.07)(1)=28

for t=2 year

I=PRT=400(0.07)(2)=56

for t=3 year

I=PRT=400(0.07)(31)=84

for t=4 year

I=PRT=400(0.07)(4)=112

Now we have table as shown below:

T I

1 28

2 56

3 84

4 112

Graphing these points we see that obtained graph best matches with First choice .

Hence first graph is the correct answer.

Draw the graph of f(x) = (x − 1)2 − 2. Start by creating a table of ordered pairs for the function. Then plot the points from th

pogonyaev

The attached graph represents the graph of f(x) = (x - 1)^2 - 2

<h3>How to plot the graph?</h3>

The equation is given as:

f(x) = (x - 1)^2 - 2

Next, we set x to -2, -1, 0, 1 and 2.

So, we have:

f(-2) = (-2 - 1)^2 - 2 = 7

f(-1) = (-1 - 1)^2 - 2 = 2

f(0) = (0 - 1)^2 - 2 = -1

f(1) = (1 - 1)^2 - 2 = -2

f(2) = (2 - 1)^2 - 2 = -1

This means that the table of values is

x f(x)

-2 7

-1 2

0 -1

1 -2

2 -1

Next, we plot the above points and connect them.

See attachment for the graph of f(x) = (x - 1)^2 - 2
