Which name applies to the apple pair at the right?
When two angles sum up to 90° they are called complementary angles.
Since the sum of angle 1 and angle 2 = 90°, they will be called each other's complements.
Thus, the angle pair is called complementary angles.
▪︎Therefore, the correct option is (C) complementary
(-3x2 + 6x - 12) + (5x + 9) is equivalent to expression __
Answer:
[tex]-3x^{2}+11x-3[/tex]
Step-by-step explanation:
[tex](-3x^{2}+6x-12)+(5x+9) = -3x^{2} + 6x - 12 + 5x + 9 = -3x^{2} + 11x - 3[/tex]
Answer:
see below
Step-by-step explanation:
Here are the simplified results of each polynomial combination.
(5x2 + 2x + 1) + (6x2 − 3x + 9)
= 5x2 + 2x + 1 + 6x2 − 3x + 9
= 5x2 + 6x2 + 2x − 3x + 1 + 9
= 11x2 − x + 10 (B)
(-3x2 + 6x − 12) + (5x + 9)
= -3x2 + 6x − 12 + 5x + 9
= -3x2 + 6x + 5x − 12 + 9
= -3x2 + 11x − 3 (A)
(8x + 16) − (3x2 − 3x − 15)
= 8x + 16 − 3x2 + 3x + 15
= -3x2 + 8x + 3x + 16 + 15
= -3x2 + 11x + 31 (D)
(5x2 + 23x − 7) − (x2 − 4x + 21)
= 5x2 + 23x − 7 − x2 + 4x − 21
= 5x2 − x2 + 23x + 4x − 7 − 21
= 4x2 + 27x − 28 (C)

An artist is creating a structure for the bull by store in the shape of sphere the sculpture will be filled with it seem it and has a diameter of 24 inches use to approximate the volume of sculpture in cubic inches to the nearest hundredth
Answer:
[tex]V=7238.22\ \text{inches}^3[/tex]
Step-by-step explanation:
The diameter of a sphere, d = 24 inches
Radius, r = 12 inches
We need to find the volume of sculpture which is in the shape of sphere. The formula for the volume of a sphere is given by :
[tex]V=\dfrac{4}{3}\pi r^3\\\\V=\dfrac{4}{3}\pi \times (12)^3\\\\V=7238.22\ \text{inches}^3[/tex]
So, the volume of the sculpture is [tex]7238.22\ \text{inches}^3[/tex].
The budget for a school dance is $390.00. Decorations and refreshments cost $150.00. The band charges a fee of $100.00 plus an additional $35.00 per hours. What is the maximum number of hours the school can have the band play at the dance?
Answer:
The maximum number of hours the school can have the band play at the dance is 4.
Step-by-step explanation:
150 + 100 + 35x ≤ 390
250 + 35x ≤ 390
subtract 250 from both sides
35x ≤ 140
divide by 35 on both sides
x ≤ 4

"A store has a sale where every item has a sale price that is 25% less than the regular price. Write an expression that represents
the sale price of an item if the regular price is p dollars."
Levi said, "To find 25% of a number, I should multiply by 0.25. So the sale price of an item will be 0.25p."

Mia invested $52,000 in an account paying an interest rate of 3.1% compounded continuously. Assuming no deposits or withdrawals are made, how long would it take, to the nearest tenth of a year, for the value of the account to reach $62,100?
Answer:
about 6 years 3 months
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 3.1%/100 = 0.031 per year,
then, solving our equation
t = 10100 / ( 52000 × 0.031 ) = 6.2655
t = 6.2655 years
The time required to
accumulate simple interest of $ 10,100.00
from a principal of $ 52,000.00
at an interest rate of 3.1% per year
is 6.2655 years (about 6 years 3 months).

Ludwig the cow has decided to build a rectangular fence around his part of a pasture because Gustav the goat thinks he is cool and can eat all the grass he wants, including the grass on Ludwig’s side of the pasture. Ludwig determines that the perimeter of the fence has to be greater than 132 yards. If Ludwig needs the width of the fence to be eight less than the length, determine, to the nearest whole yard, the smallest the length of the fence can be and still have a perimeter greater than 132 yards.
9514 1404 393
Answer:
38 yards
Step-by-step explanation:
Let x represent the length and y the width, both in yards. Then the required relations are ...
2(x+y) > 132 . . . . . . the perimeter is greater than 132 yards
y = x - 8 . . . . . . . . . . width is 8 less than length
Substituting for y in the first equation gives ...
2(x +(x -8)) > 132
4x -16 > 132
x -4 > 33
x > 37
The smallest length the fence can be is 38 yards.
__
Check
At that length, the width is 30 yards, and the perimeter is 2(38+30) = 136 yards. If the length were 37 yards, the perimeter would be 132 yards, which is not greater than 132 yards.

A circle has a radius of 5 ft. What is the area
Answer:
78.5 ft²
Step-by-step explanation:
The area of a circle is given by
Area = πr²
where r is the radius = given as 5 ft
π = 3.14
substituting the values into the equation, we get
Area
= πr²
= (3.14) (5²)
= 78.5 ft²
Answer:
Solution :Here, we have given that the radius of circle is 5 ft.
So, finding the area of circle by substituting the values in the formula :
[tex]\longrightarrow{\pmb{\frak{Area_{(Circle)} = \pi{r}^{2} }}}[/tex]
[tex]\longrightarrow{\frak{Area_{(Circle)} = 3.14 \times {(5)}^{2}}}[/tex]
[tex]\longrightarrow{\frak{Area_{(Circle)} = \dfrac{314}{100} \times {(5 \times 5)}}}[/tex]
[tex]\longrightarrow{\frak{Area_{(Circle)} = \dfrac{314}{100} \times {(25)}}}[/tex]
[tex]\longrightarrow{\frak{Area_{(Circle)} = \dfrac{314}{100} \times 25}}[/tex]
[tex]\longrightarrow{\frak{Area_{(Circle)} = \dfrac{314 \times 25}{100}}}[/tex]
[tex]\longrightarrow{\frak{Area_{(Circle)} = \dfrac{7850}{100}}}[/tex]
[tex]\longrightarrow{\frak{Area_{(Circle)} = 78.50 \: {ft}^{2} }}[/tex]
[tex]\star \: {\underline{\boxed{\sf{\purple{Area_{(Circle)} = 78.50 \: {ft}^{2}}}}}}[/tex]
Hence, the area of circle is 70.50 ft².

A diver in the Olympics dives off a platform 15 m above the water’s surface and descends to a depth of 5 m below the surface. How many meters are traveled by the diver during the dive ?
Let the water surface be 0.
He starts at 15 and gets to the water surface of 0 so he travels 15 meters.
He then goes 5 meters below the surface.
15 + 5 = 20 total meters.
Answer:
20m
Step-by-step explanation:
the diver starts on a platform 15m above the water surface, which we will call 0. if he goes from the platform to -5m under the water, then he would have traveled 20m.
Calculate the volume of the prism by first finding the total number of half-unit cubes that will fill it. There are 8 half-unit cubes in every unit cube.
Answer:
10 half unit cubes
Volume = 1 1/4 unit³
Step-by-step explanation:
Volume of rectangular prism = Length * width * height
From the dimensions given in the picture :
Volume = 1 * 1/2 * 2 1/2
Volume = 1 * 1/2 * 5/2
Volume = 5/4 unit³
Volume = 1 1/4 unit³
Number of half unit cube per unit³ = 8
Total number of half unit cubes that will fill it:
Number of half unit cube per unit³ * volume
8 * 5/4
= 40 /4
