Answer:
Surface Area: 1320
Volume: 2160
Step-by-step explanation:
Before calculating Volume and Surface Area, we need to calculate the missing side of the right triangle using the Pythagoreon theorem: [tex]a^2+b^2=c^2[/tex]
where c is the hypotenuse, 26.
Substituting the values into the equation you get:
10^2 + b^2 = 26^2
100 +b^2 = 676
Subtract 100 from both sides.
b^2 = 576
b = 24
Now that we have the missing side, we can calculate the rest of the question.
Surface Area = 2([tex]\frac{1}2[/tex] × 24 × 10) + (18 × 26) + (18 × 24) +(18 × 10)
240 + 468 + 432 + 180 = 1320 unit^2
Volume = [tex]\frac{1}2[/tex] × base × height × length
[tex]\frac{1}2[/tex] × 24 × 10 × 18 = 2160 unit^2

The temperature in Calgary at 9 a.m. was – 23 C.
By 11 a.m., it had warmed up by 8 C.
By noon, it had warmed up by another 3 C.
But by 2:00 p.m. it had cooled by 6 C.
What was the temperature in Calgary at 2:00 p.m.?
Answer:
-18 C°
Step-by-step explanation:
Warmed means add cooled means subtract
starting at -23 it warmed by 8 add 8
-15
it warmed by 3 more add 3
-12
then it cooled by 6 subtract 6
-18

(-1, -5)?
Answer:
x = -1
Step-by-step explanation:
(-1 , 6) ; (-1 , -5)
There is no change in x-coordinate values.
So, the is parallel to y-axis

Answer: 34 in^3
Step-by-step explanation:
Surface area of triangle = 1/2 x 3.4 x 2.5 = 4.25
To find the volume of the prism, multiply the surface area of the triangle by length.
So 4.25 x 8 = 34 in^3

What’s the length of a segment whose endpoints are (8,-6) and (-4,2)?
Answer:
Step-by-step explanation:
Imagine or draw a triangle with horizontal leg length 8 - (-4), or 12, and vertical leg length |-6 - 2|, or 8. Use the Pythagorean Theorem to find the length of the hypotenuse:
length of hypotenuse = +√(8² + 12²) = √208 = 4√13 (Answer A)

Twenty years ago, Mr. Davis purchased his home for $160,000. Since then, the value of
the home has increased about 5% per year. How much is the home worth today?
Answer:
The home is worth $424,528 today
Step-by-step explanation:
To get the worth of the home today, we are going to use the exponential formula
We have this as follows;
A = P(1 + r)^t
where A is the value of the house after some time t
P is the initial value the home was worth which is $160,000
r is the rate of increase in the price of the home which is 5% = 5/100 = 0.05
t is the number of years which is 20
substituting these values;
A = 160,000(1 + 0.05)^20
A = $424,528
Chris types at an average speed of 50 words per minute. He has already typed 1,250 words of his final paper. The paper has to be
more than 3,750 words. Which of the following inequalities could be used to solve for x, the number of minutes it will take Chris to
type his paper?
OA. 50x > 3,750
ОВ.50x - 1,250 > 3,750
OC. 50x > 5,000
OD. 50x + 1,250 > 3,750
Answer:
D. 50x+1,250>3,750

6(x + 3) - (x + 4) = -11
Answer: x=-5
Step-by-step explanation:
Distribute
6(x+3)-1(x+4)=-11
6x+ 18-1(x+4)=-11
6x +18-x-4=-11
Subtract the numbers
6x +18-x-4=-11
6x +14-x=-11
Combine like terms
6x +14-x=-11
5x +14=-11
subtract 14 from both sides of the equation
5x +14=-11
5x +=14-14 = -11 -14
simplify
5x=-25
divide both sides
x=-5

Find the volume of the cylinder in terms of x and to the nearest tenth
Answer:
12.57 in^3
Step-by-step explanation:
The easiest way to do this is to find the area of the circle surface and multiply it by the height
to find area the formula is pi r^2 and we are given the radius
so we plug in pi(2^2)=pi(4)= roughly 12.57
then we multiply the area by the height which is 1 so it would be the same
12.57(1)=12.57

The area of the base of a box is 825 square centimeters. It has a height of 26 centimeters. What is the volume of the box in cubic centimeters?
Answer: 4950 cubic centimeters.
Step-by-step explanation:
We know that, the volume of box = Base area x height
Given: area of the base of a box = 825 sq. centimeters
height = 6 centimeters.
Then, Volume of the box in cubic centimeters = 825 x 6
= 4950 cubic centimeters.
hence, the volume of the box in cubic centimeters = 4950 cubic centimeters.
What is the measure of angle z in this picture?
Answer:
z = 137 degrees
Step-by-step explanation:
Angle 43 and angle z make a straight line, which is 180 degrees
43+z = 180
Subtract 43 from each side
43+z-43 = 180-43
z =137
