Answer:
4.78 cm
Step-by-step explanation:
The formula for the volume of a cone of radius r and height h is
V = (1/3)πr²h. Here, V = 31.254 cm³ and r = 2.5 cm.
We begin by solving V = (1/3)πr²h for the unknown height, h:
31.254 cm³ 3(31.254 cm³) 93.762 cm³
h = ------------------------ = -------------------------- = -------------------- ≈ 4.78 cm
(1/3)πr² π(2.5 cm)² 19.635 cm²
16 + x = 22
Please help
Answer:
6
Step-by-step explanation:
All you have to do is subtract 16 from both sides!
16+x=22
-16 -16
x=6
I hope this helps, and have a great day! :)
Andrew says that 10x + 6 and 5x + 11 are equivalent because they both equal 16 when x= 1. Is Andre correct in saying they're equivalent?
Hey love! <3
Answer:
The right answer is that Andrew is correct in saying they are equivalent.
Step-by-step explanation:
In Andre's statement x is equal to 1 unless further added into the statement, both sides equal the same amount after simplification.
Hope this is helpful! (⊙‿⊙✿) Sincerely, Kelsey from Brainly.

The measure of Juan's angle is modeled by 2x2+6x−5. The measure of Sally's angle is modeled by 8x+31. Which polynomial expression represents how much greater the measure of Juan's angle is than Sally's?
a.) 2x2−2x−362 x squared minus 2 x minus 36
b.) 2x2−2x−262 x squared minus 2 x minus 26
c.) 2x2+2x+362 x squared plus 2 x plus 36
d.) 2x2+14x+26
Answer: 2x^2-2x-36 is the correct answer
Step-by-step explanation: Add 8x+31 and 2x^2-2x-36 and you will get 2x^2+6x-5. (i took the test and got it correct)

In a random sample of 200 customers at a restaurant, 140 customers ordered french fries. If the restaurant typically has 1,000 customers in a day, about how many will probably order french fries?
Answer: 700 customers
Step-by-step explanation:
In a random sample of 200, 140 people ordered French fries.
Find out the percentage of people who ordered French fries:
= 140 / 200
= 70%
If the restaurant usually has 1,000 customers a day, based on the rate of people who ordered French fries out of 200 people - 70% - the number of people who will probably order French fries are:
= 70% * 1,000
= 700 customers

In order to get the answer, first calculate the product for [tex]3*(3^4)=3x[/tex] which will get you [tex]3^5=3x[/tex].
Then you'll want to divide both sides of the equation by 3, taking you from [tex]3^5=3x[/tex] to [tex]3^4=x[/tex].
After that, you need to evaluate the power, so now you have went from [tex]3^4=x[/tex] to 81=x.
And the final step would be to switch the sides of the equation. So instead of ending with 81=x, you'll end with x=81.

Answer:
27
Step-by-step explanation:
6x3=18, which means the bottom half of the shape is 18. The top half is a triangle, and triangles are half a square or rectangle. So again, 6x3=18. 18/2=9. So 18+9=27. So the ANSWER IS 27

PLZZZ HELP MEEE YALL .!.!.!.!
Answer:
Step-by-step explanation:
Area of the rectangle = length * width
= 10 * 5
= 50 m²
Area of the smaller rectangle that is white color = 7 * 2
= 14 m²
Triangle:
base = b = 5 m
Height = h = 16 - 10 = 6 m
Area of triangle = [tex]\frac{1}{2}*b*h\\[/tex]
[tex]= \frac{1}{2}*5*6\\\\= 5*3\\\\= 15 m^{2}[/tex]
Area of shaded area = area of bigger rectangle - area of smaller rectangle + area of triangle
= 50 - 14 + 15
= 21 m²
triangle ABC has side lengths 8 inches, 17 inches, and 15 inches. Sofia uses the following steps to conclude that triangle ABC is not a right triangle.
[tex]a^{2} +b^{2} =c^{2} \\8^{2} +17^{2} =15^{2} \\64+289=225\\353\neq 225[/tex]
What mistake did Sofia make?
A Sofia made a calculation error.
B Sofia used the length of one of the legs as c when she should have used the length of the longest side as c.
C Sofia does not know if triangle ABC is a right triangle, so she cannot use the Pythagorean Theorem or its converse.
D Sofia’s conclusion is incorrect. When the sides of a triangle do not satisfy a2+b2=c2, you cannot conclude that the triangle is a right triangle.
Answer: Its b.
Step-by-step explanation: The hypothenuse is the biggest number and the leg is the two shortest numbers.
Find two consecutive integers whose product is 90.

We sell ice cream at a retail store, which we operate 50 weeks per year. Whenever we order from our supplier we incur a $250 ordering charge. Customer demand is 200 pounds per week and it costs us $35 per pound per year to hold the ice cream in proper storage. a) What is the EOQ?
Answer:
the EOQ is 378 units
Step-by-step explanation:
The computation of the economic order quantity(EOQ) is shown below:
EOQ is
[tex]= \sqrt{\frac{2\times A\times O}{C} } \\\\= \sqrt{\frac{2\times 200 \times 50\times \$250}{\$35} }[/tex]
= 378 units
Here A represent the annual demand
O represent the ordering cost
And, C represent the carrying cost
hence, the EOQ is 378 units

(1,-1)
Step-by-step explanation:
the length of a rectangle is 7 cm more than its width and the area is 30 cm find the length, width and the perimeter
Answer:
Step-by-step explanation:
let width=x
length=x+7
x(x+7)=30
x²+7x-30=0
x²+10x-3x-30=0
x(x+10)-3(x+10)=0
(x+10)(x-3)=0
either x=-10 (rejected being negative)
or x=3
width=3 cm
length=3+7=10 cm
Perimeter=2(10+3)=2×13=26 cm

Step-by-step explanation:
the sum of two numbers is 2 to the power of 6. the one number is equal to 6 to the power of 2. determine the value of the other number.
Answer:
28
Step-by-step explanation:
x+y=2^6
and we have x=6^2=36
36+y=64(since 2^6= 64)
then,y=64-36=28
so the value of the other number is 28

Find the measure of Angle C. thanks!!
Answer:
Use the formula for the trapeze
Step-by-step explanation:
Answer:
∠ C = 88°
Step-by-step explanation:
The opposite angles in a cyclic quadrilateral sum to 180°, then
8x - 4 + 7x + 4 = 180 , that is
15x = 180 ( divide both sides by 15 )
x = 12
Then
∠ C = 7x + 4 = 7(12) + 4 = 84 + 4 = 88°
What is the value of x?
Answer:
x = 39
Step-by-step explanation:
The angle between a tangent and the radius of a circle at the point of contact is 90° , then
x = 180 - (90 + 51) = 180 - 141 ← angle sum of triangle
x = 180 - 141 = 39
x + 51 = 90
x = 90 - 51
x = 39°

Find the length of a rectangular prism having a volume of 60 cubic meters, width of 2 1/2 meters, and height of 3 1/3
Answer:
7 1/5 m
Step-by-step explanation:
Find the length of a rectangular prism having a volume of 60 cubic meters, width of 2 1/2 meters, and height of 3 1/3
Volume of a rectangular prism = Length × Width × Height
Length = Volume/ Width × Height
Length = 60 m³/2 1/2 m × 3 1/3 m
Length = 60 m³/8 1/3 m²
Length = 60 m³÷ 8 1/3 m²
= 60 m³ ÷ 25/3 m²
=( 60 × 3/25 )m
= 180/25 m
Length = 7 1/5 m
