Hi!

To find the area of a rectangle, multiply base times height.

5 x 10 = 50

Now we need to subtract the area of the non-shaded part.

2 x 2 = 4
50 - 4 = 46

The answer is 46

Hope this helps! :)

First, find the area of the shaded region plus the white region, which is 5*10, or 50. Now find the white region only, which is 2*2, or 4. Now subtract 4 from 50 to get the area of the shaded region only. You will get 46. So 46 is your answer.

Hope the explanation helped!

For the data that are shown on the graph below, which best describes within which range of x-values extrapolation occurs? On a g

aalyn [17]

Given:

On a graph, points are at (0, 15), (1, 17), (3, 18), (4, 20) and (6, 22).

To find:

The range of x-values extrapolation occurs.

Solution:

Consider the below figure attached with this question.

From the graph or given points it is clear that the x-values are 0, 1, 3, 4, 6.

It means the x-values are from 0 to 6.

So, the range of the x-values is $x\geq 0$ or $x\leq 6$ .

The required compound inequality for the range of x-values is $0\leq x\leq 6$ .

Therefore, the correct option is D.

Pam bought 50 kg of sugar. She used 10 kg of sugar. What percentage of sugar was left? (step by step answer would be appreciated

galben [10]

Answer:

80%

Step-by-step explanation:

50 x 50 would be 100 and 50kg=100% and 10 x 2 = 20 so you used 20% therefore you have 80% left.

The combined average weight of an okapi and a llama is 450450450 kilograms. The average weight of 333 llamas is 190190190 kilogr

Kisachek [45]

I'm going to assume that you meant 450kg for the combined weight, 190kg more and 3 Llamas. I'm pretty sure Llamas and Okapis don't weigh 450450450kg (that's 993,073,252 pounds). :)

x= Okapi weight
y= Llama weight

EQUATIONS:
There are 2 equations to be written:

1) 450kg is equal to the weight of one Okapi and one Llama

450kg= x + y

2) The weight of 3 llamas is equal to the weight of one Okapi plus 190kg.

3y=190kg + x

STEP 1:
Solve for one variable in one equation and substitute the answer in the other equation.

450kg= x + y
Subtract y from both sides
450-y =x

STEP 2:
Substitute (450-y) in second equation in place of x to solve for y.

3y=190kg + x
3y=190 + (450-y)
3y=640 -y
add y to both sides

4y=640
divide both sides by 4

y=160kg Llama weight

STEP 3:
Substitute 160kg in either equation to solve for x.

3y=190kg + x
3(160)=190 + x
480=190 + x
Subtract both sides by 190

290= x
x= 290kg Okapi weight

CHECK:
3y=190kg + x
3(160)=190 + 290
480=480

Hope this helps! :)
