Find the volume of each sphere. Rand to the nearest tenth!
A) 49.2
B) 268.1
C) 102.05
D) 153.3
what is the function of f(0)
Answer:
Steps:
1. The zero of a function is the x-value that, when plugged into a function, makes the function equal to 0.
2. f(x) means that we have a function of x.
3. The zero of the function f(x)=2x-2 is the x-value that makes f(x) = 0.
4. So we can just set the function equal to 0, and then solve for x!
Hope this helps

Square OPQR is inscribed in triangle ABC. The areas of △AOR, △BOP, △CRQ are 1, 3, and 1, respectively. What is the area of square OPQR?
Answer:
9 units²
Step-by-step explanation:
We know that ΔCRQ and ΔBOP are right triangles because RQ and OP are perpendicular to CB.
ΔAOR must also be a right triangle because ∠AOR = ∠OBP and ∠ARO = ∠RCQ.
Because of the Angle-Angle-Angle theorem, we know that ΔAOR ≅ ΔBOP ≅ ΔCRQ.
AR/AO = OP/PB
3(1/2)(AR)(AO) = (1/2)(OP)(PB)
PB = 6, OP = 3
3 x 3 = 9 units²
The area of square OPQR is 9 units².
Calculation of the area of square:Since
ΔCRQ and ΔBOP are right triangles since RQ and OP are perpendicular to CB.
Also,
ΔAOR must also be a right triangle due to ∠AOR = ∠OBP and ∠ARO = ∠RCQ.
So it can be like
AR/AO = OP/PB
3(1/2)(AR)(AO) = (1/2)(OP)(PB)
PB = 6, OP = 3
= 3 x 3
= 9 units²
hence, The area of square OPQR is 9 units².

Trey pourd 5 1/2 cups of birdseed into an empty bird feeder. The bird feeder is now 3/4 full. How much more for it to be full.
Answer:
1 and 1/3 Cups
Step-by-step explanation:
3/4 of the birdfeed is filled by 5.5 cups
3/4 x= 5.5
solve for x my multiplying by 4/3 to see how much space is left in the feeder
=1 and 1/3 space left
The cup needs 1 5/6 cups more birdseed to fill the bird feeder completely.
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
If the bird feeder is 3/4 full after Trey poured 5 1/2 cups of birdseed, then we can find the total capacity of the bird feeder by dividing the 5 1/2 cups by 3/4:
5 1/2 / 3/4 = 22/4 / 3/4 = 22/4 x 4/3 = 88/12 = 22/3
So the bird feeder can hold 22/3 cups of birdseed when it's full.
Since the bird feeder is already 3/4 full, we need to fill the remaining 1/4 of the bird feeder
On simplifying the equation , we get
1/4 x 22/3 = 22/12 = 1 10/12 cups
Hence , we need 1 10/12 cups or 1 5/6 cups more birdseed to fill the bird feeder completely

Sebastian is making bags of trail mix for hiking club. He will use 21 ounces of walnuts, 10.2 ounces of almonds, and 15.6 ounces of cashews. This amount makes 24 bags of trail mix. How many ounces are in each bag?
Answer:
1.95 ounces
Step-by-step explanation:
ounces in each bag = total ounces in 24 bags / number of bags
total ounces in 24 bags = 21 ounces of walnuts + 10.2 ounces of almonds + 15.6 ounces of cashews = 46.8 ounces
46.8 / 24 = 1.95 ounces
convert y=x^2-4x+5 to vertex form by completing the square
Answer:
The vertex form will be:
[tex]y(x)=(x-2)^{2}+1[/tex]
Step-by-step explanation:
The equation of the vertex form of a quadratic equation is given by:
[tex]y(x)=a(x-h)^{2}+k[/tex]
Where:
a is a coefficient
h is the x value of the vertex
k is the y value of the vertex
To completing the square we just need to add and subtract the square of the term with x divided by 2.
[tex]y(x)=x^{2}-4x+(\frac{4}{2})^{2}-(\frac{4}{2})^{2}+5[/tex]
[tex]y(x)=x^{2}-4x+4-4+5[/tex]
[tex]y(x)=(x-2)^{2}-4+5[/tex]
Finally, the vertex form will be:
[tex]y(x)=(x-2)^{2}+1[/tex]

jose bought 9 movie tickets for a total of $54. Adult tickets cost $8 each and child tickets
cost $3.50 each. How many adult tickets did he buy?
well i cant tell because you did not tell me how many kid tickets he bought
mr and mrs Jones buy cinema tickets for themselves and their three children. the cost of an adult ticket is £6 more than a child ticket. the cost of the five tickets is £45
work out the cost of an adult ticket
Answer:
£12.60
Step-by-step explanation:
let the cost of a child ticket be x then the cost of an adult ticket is x + 6
Sum the costs and equate to 45
x + 6 + x + 6 + 3x = 45 , that is
5x + 12 = 45 ( subtract 12 from both sides )
5x = 33 ( divide both sides by 5 )
x = 6.6
Cost of and adult ticket = x + 6 = 6.60 + 6 = £12.60
The cost of an adult ticket is £12.60.
What is linear equation?Equations whose variables have a power of one are called linear equations. One example with one variable is where ax+b = 0, where a and b are real values and x is the variable.
Given:
Mr. and Mrs. Jones buy cinema tickets for themselves and their three children.
That means, there are two adults and three children.
The cost of an adult ticket is £6 more than a child ticket.
Let n be the cost of a child.
The cost of the five tickets is £45.
That means,
the equation,
2(n+6) + 3n = 45
n = 33/5
n = 6.6
The cost of an adult ticket is £12.60.
Therefore, the cost of an adult ticket is £12.60.
