PLease help how do i solve this?!

Answer:

option B

Step-by-step explanation:

let the height=x

base=x

Area=½bh

72=½x•x

72×2=x²

144=x²

x=√144=12

Answer:

12

Step-by-step explanation:

12 x 12= 144

144/2= 72

For x = 4

7 x 4 + 49 = 77

Answer Is 77

Answer:

26

Step-by-step explanation:

If m=6, -5 times 6 is -30. -2 times -2 is 4.

-30 plus 4 is 26.

Answer:

|x|=-4 is immposible, absolute value is the distance of any number away from zero hence is it imposible for it to be a negative number

Hope this helps! :)

Answer:

y=-3x

Step-by-step explanation:

The meaning of direct proportion is that the ratio remains the same, and the ratio will only remain the same if y= a constant number into x

Answer:

Answer:

7250

Step-by-step explanation:

145,000

x

0.05

145000 / 100 = 1450.

1450 x 5 = 7250

Answer:8

Step-by-step explanation: negative times negative =positive

and times 8/5 by 5/1  .

When multiplying fractions, simply multiply the numerators together and multiply the denominators together.

-8 * -5 = 40

5 * 1 = 5

-8/5 * -5/1 = 40/5

40/5 = 8

Answer:

Rotate the image by 90 degrees (left) Rotate the image by 180 degrees (upside down) Rotate the image by 270 degrees (right) Rotate the image by 360 degrees (original position) Rotate the image by 90 degrees. Rotating the image by 90 degrees would flip the image to the left side.

Step-by-step explanation:

Answer:

(a) 11.

(b) 5.

Step-by-step explanation:

(a)√124:

11*11 = 121 so an estimate is 11.

(b) ∛124

5*5*5 = 125

So an estimate is 5.

Answer:

A(9) is the very correct answer

Answer:

None of the Above

Step-by-step explanation:

Key Skills required are: One Variable Equations, Supplementary Angle Pairs, Substitution, and Triangles.

1) To find the measure of Angle C, we first need to find the measure of angle DBC and Angle D.

2) We are given that Angle EBA is x and Angle EBD is 4x+13 and Angle D is 3x + 9 (we will use Angle D later in the problem)

3) Now, we need to use the fact that Angle EBA and Angle EBD are supplementary (they form a linear pair, so they are supplementary).

A pair of supplementary angles add up to  180 degrees (as they form a straight angle).

4) x + 4x + 13 = 180

5) Combine like terms --> 5x + 13 = 180

6) Move 13 to the other side --> 5x = 167

7) Divide by 5 and solve for x: x= 33.4

8) Now we got that x is 33.4, we can get the measure of angle DBC and Angle D.

9) Angle DBC is congruent to Angle EBA. So to find the measure of DBC we need to find the measure of Angle EBA. EBA is just x, so it is 33.4 degrees

10) Therefore, Angle DBC also measures 33.4 degrees.

11) To find angle D, we substitute x into 3x + 9 (We are given angle D is 3x + 9 based on the problem)

12) 3(33.4) + 9 = 100.2 + 9 = 109.2

13) Now we use the interior angles sum of a triangle to find Angle C.

The interior angles of a triangle sum up to 180 degrees.

14) With the statement above we can make this equation: 109.2 + 33.4 + Angle C = 180

15) Simplify by combining like terms: 142.6 + Angle C = 180

16) 37.4 degrees would be the measure of C, so I feel it would be none of the above.

Hope you understood and have a nice day!! :D

Answer:

the answer would be 47.75981574 or 47.76

Answer:

3- 47.76

Step-by-step explanation:

hundredth is the 2 place after decimal, so we can also say 2 d.p for rounding to the nearest hundredth

Answer:

D.

Step-by-step explanation:

2 is it's length while in the perinthesis is x for its length plus the width which is doubled, explained by the x.

Answer:

Step-by-step explanation:

25 feet per minute

in 10 minutes

25ft*10=250ft

the diver is 250+200=450

the diver was at 450 below the sea level

Answer:

450 feet below sea level

Step-by-step explanation:

So:

We are looking at 10 minutes ago. If he is being pulled up, that means before he was even more down.

Therefore 25 feet is 1 minute so 10 minutes is 250 feet.

As he was more down below sea level you add 200 feet below sea level with 250 feet below sea level.

This will give you 450 feet below sea level.

I hope this helps!

Answer:

I believe the answer is C.

Answer:

what grade

Step-by-step explanation:

to know the rule

Answer:

$97.2

Step-by-step explanation:=Given

The expression p + 0.08p

where P= the initial price

let y be the total cost, so that

y=p + 0.08p

for p=$90

y=90+0.08*90

y=90+7.2

y=$97.2

Hence the total cost for a $90 price is $97.2

Answer: 18

Step-by-step explanation:

Answer:

18

Step-by-step explanation:

4 goes into 24 6 times so you would minus 6 from 24 so 24-6= 18

Answer:

c = x mi d= x mi

Step-by-step explanation:

Answer:

x>-3 (if the = is meant to be +)

Step-by-step explanation:

Distribute the 2: 2x+10>4

Subtract 10 from both sides: 2x>-6

Divide both side by 2: x>-3

Answer:

4.5

Step-by-step explanation:

when the height is 0 the ball will hit the ground

so the equation is

-12t²+54t=0

12t²-54t=0

2t²-9t=0

t(2t-9)=0

t=0

t=4.5

so the answer is

4.5
