Answer:
x = 26
Step-by-step explanation:
[tex] {(x - 21)}^{2} = 25 \\ x - 21 = \sqrt{25} \\ x - 21 = 5 \\ x = 5 + 21 \\ x = 26[/tex]
Answer:
x = 26, x = 16.
Step-by-step explanation:
(x - 21)² = 25
Expand the factor.
(x - 21)(x - 21) = 25
Multiply using FOIL.
x² - 42x + 441 = 25
Subtract 25 from both sides.
x² - 42x + 416 = 0
Factor.
(x - 26)(x - 16) = 0.
Set both expressions to 0 and solve.
x - 26 = 0
Add 26 to both sides.
x = 26
x - 16 = 0
Add 16 to both sides.
x = 16

Luke sold 4 times as many books as Maurice. If Maurice had sold 18 more books, he would have tied Luke for first place. How many books did Luke sell?
Answer:
24
Step-by-step explanation:
I guessed and checked but 24 -18 is 6 and 6 times 4 is 24
M + 18 = 4M
18 = 4M - M
18 = 3M
M = 18/3 = 6
4M = 4(6) = 24 sold by Luke

What is the measure of ∠A, the exterior angle of the triangle shown below? F. M∠A = 92°, because 180 – (50 + 38) = 92. G. M∠A = 272°, because 180 – (50 + 38) = 92 and 92 + 180 = 272. H.M∠A=78°,because 50–38=12and90–12=78. J. M∠A = 88°, because 50 + 38 = 88.
Answer: A is 88
Step-by-step explanation:
Sum of all angles is 180 degree.
Let the third interior angle be x.
38+50+x=180
88+x=180
x= 92
A and X are in linear pair.
A+X=180
A+92=180
A=88

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using the equation, what height was the rocket launched from? y=-16x^2+57x+32
9514 1404 393
Answer:
32 feet
Step-by-step explanation:
0 seconds after launch, the rocket is still sitting on the tower. Its height is...
y = -16(0^2) +57(0) +32
y = 0 + 0 + 32 = 32
The rocket was launched from a tower 32 feet high.

During the 1990s, the forested area of Guatemala decrelised at an average rate of 1.7%.
If the forested area in Guatemala in 1990 was about 34 400 square kilometers, write an equation for the forested area for t years
after 1990. If this trend continues, predict the forested area in 2015.
Answer:
A is correct answer
Step-by-step explanation:
Here, we want to write an equation for a depreciation
The general form is;
V = I( 1 - r)^t
V is the present value in 2015
I is the initial value in 1990 which is 34,400
r is the decrease rate which is 1.7/100 = 0.017
t is the difference in years which is 2015-1990 = 25
Substituting these values, we have
V = 34,400(1-0.017)^25
V = 22,407.65 km^2

A cylindrical soup can has a diameter of 3.8 in. and is 5.4 in. tall. Find the volume of the can.
Answer:
the volume of the can is 61.21 cubic inches
Step-by-step explanation:
Given that
The diameter is 3.8 inches so the radius would be = 3.8 ÷ 2 = 1.9 inches
And, the height of the cylindrical soup is 5.4 inches
We need to find out the volume of the can
As we know that
The volume of the can is
[tex]Volume = \pi r^2h\\\\Volume = 3.14 \times 1.9^2 \times 5.4[/tex]
Volume = 61.21 cubic inches
Hence, the volume of the can is 61.21 cubic inches

You choose two different movies on a list at random. Out of 10 movies on the list, 6 are action movies. The first movie you choose is an action movie. What is the probability that the second movie is also an action movie? Write your answer as a fraction in simplest form.
Answer:
5/9
Step-by-step explanation:
You have 10 movies in total. You take 1 out of 6 action movies. Now you have 5 action movies left, so that means the probability is 5/9. It's 5/9 because you chose 1 action movie out of 10 movies in total, so that means there are 9 movies in total left.

What is Pythagoras theorem?Pythagoras theorem says that in a right angle triangle, the square of the hypotenuse side is equal to the sum of the square of the other two legs of right angle triangle.
The image of the given problem is attached below. In this diagram, the radius of the circle is 1.5 meter long.
The triangle ABC shown in the graph is right angle triangle as, the tangent of the circle is perpendicular with the radius of it at the point of contact.
Thus, by the Pythagoras theorem,
[tex](AB)^2+(BC)^2=(AC)^2\\(1.5)^2+(x)^2=(1.5+1)^2\\(x)^2=(2.5)^2-(1.5)^2\\x=\sqrt{6.25-2.25}\\x=\sqrt{4}\\x=2\rm\; units[/tex]
