First of all, as the line (y<3x) is dotted, so the sign of its inequality is just <, not <=

Options b ad c are out

To check which region is the right one for the second inequality (y>=-0.5x-4), plug in the origin point (0,0) into the inequality, if it satisfies then the region included the origin is the shaded region (the solution you want), if not, the other region is the solution..

0>+0-4 0>=-4

Yes, it satisfies,,

SO it is A

ariel is saving money for a new computer that costs $650. she has $150, which she puts into an account. then she adds $25 each w

20 weeks

The initial equation is 25x+150=650. Since she already has 150, we can subtract that from the total to get 500. We now have that 25x=500. Divide by 25 on both sides to get 20 weeks

A jug of syrup holds 12 cups convert 12 cups to pints

Fittoniya [83]

1 pint = 2 cups or 1 cup = 1/2 pint
x pints = 12 cups
(12 cups) / 2 = 6 pints
12 cups is equivalent to 6 pints

Question 1:

Look at the first attached image.

We want to solve for the height of the smaller building. Let's start by making a right triangle with angle of 15 degrees and adjacent side of 51 m.

Let's solve for the other leg. Multiply the tangent with 51 m to get the length of the other leg.

$51*tan(15)$
$\approx 14$

Now, subtract that from 207 to get the height of the smaller building.

$207-14=193$

That's your answer.

Question 2:

The angle of elevation is congruent to the angle of depression because they are alternate interior angles.

Thus, you can choose the 1st and 4th choices as your answer.

Question 3:

Look at the second attached image.

Angle E is congruent to angle D for the same reasons mentioned in the last question.
We can create an equation.

$3x+1=2(x+8)$

Distributive property

$3x+1=2x+16$

Subtract both sides by 1 and 2x

$x=15$

Since E and D are congruent, just plug this value into one of the equations for E or D. You get 46.

The third choice is your answer. Hope this helps! :)

The sum of two numbers is 40 and their difference is 6.5, what is their product? show work please

Finger [1]

Let b>a,

a+b=40 so we can say a=40-b

We are told that b-a=6.5, using a found above in the equation gives us:

b-(40-b)=6.5

b-40+b=6.5

2b-40=6.5

2b=46.5

b=23.25, and since a=40-b

a=40-23.25

a=16.75

So a=16.75 and b=23.25

check...

16.75+23.25=40, 40=40

23.25-16.75=6.5, 6.5=6.5
