Adrian and Violetta gat a soccer ball. The soccer ball is size 4.They want it to be size 5.They know the diameter is 9 inches. Find the volume of the soccer ball.
Answer:
382 inches
Step-by-step explanation:
Given that :
The size of the soccer ball that Adrian and Violetta got is = 4
The diameter of the soccer ball is = 9 inches
Therefore, the radius of the soccer ball is, r = [tex]$\frac{9}{2}$[/tex] inches
So the volume of the soccer ball is :
[tex]V = \frac{4}{3} \pi r^3[/tex]
[tex]V = \frac{4}{3} \times \frac{22}{7} \times \left(\frac{9}{2}\right)^3[/tex]
[tex]V = \frac{4}{3} \times \frac{22}{7} \times \frac{9}{2} \times \frac{9}{2} \times \frac{9}{2}[/tex]
V ≈ 382 inches

Reflect - 25 a positive number or a negative number? Explain how you know.
Find the opposite of -25 and explain how you found your answer.
HURRY ⚠️
Answer:
-25 is negative
25 is positive
Step-by-step explanation:
-25 is negative because it's 25 spaces to the left of 0
25 is positive because it's 25 spaces to the right of 0
|-25| = 25; The opposite of -25 is 25

Sam rented a truck for one day. There was a base fee of $14.95, and there was an additional charge of 97 cents for each mile driven. Sam had to pay $265.21 when he returned the truck. For how many miles did he drive the truck?
Answer:
258 miles
Step-by-step explanation:
y = # miles truck driven
m = each mile driven
y = 14.95 + 0.97m
265.21 = 14.95 + 0.97m
250.26 = 0.97m
m = 258

how to solve x=7y+3 and 9y-x=-1 using the subsituation method
Answer:
x=10 y=1
Step-by-step explanation:
Write an explicit formula for the geometric sequence below and use it to find the 9th term. 256, 64, 16, 4, . . .
im doing this problem right now---
ok so a1=256 a2=64 a3=15 a4=4... find a9
the sequence divides by 1/4 every term
an=a1*r^n-1
an=(256)*(1/4)^n-1
replace n with 9
A9=(256)*(1/4)^9-1
A9=(256)*(1/4)^8
=(256)*(1/4)
A9=64^8
1/256 or a9= 0.00390625

Step-by-step explanation:
The Oates family went out to
dinner. The price of the meal was
$33.95. They left a 15% tip.
What was the total cost?
Answer:
$39.04
Step-by-step explanation:
1.Approach
To solve this problem, one must first find the amount of tip that was left, then add the value to the cost of the meal. The amount of tip given can be found by dividing the percent value of the tip by (100) and then multiplying the result by the price of the meal.
2.Find the amount of tip
To find the amount of tip that was left, divide the percent value of the tip by (100). This technique converts the percent into a decimal. After doing so, multiply the result by the cost of the meal.
Tip as a percent: 15%
Tip as a decimal: 0.15
Amount of tip left:
33.95 * 0.15 = 5.0925
Round the result
~5.09
3.Find the total bill
Disincluding the tax, one now has to add the tip to the cost of the meal to find the total amount paid.
(tip) + (price)
= (5.09) + (33.95)
= (39.04)

Answer:
The equation is ;
4x - y = 13
Step-by-step explanation:
The general equation of a straight line is;
y = mx + b
where m is the slope and b is the y-intercept
from what we are given, let us write the second equation in the general form
x + 4y = 10
4y = -x + 20
y = -1/4x + 20/4
y = -1/4x + 5
mathematically, when two lines are perpendicular, the product of their slope is -1
So for the second line with slope m2
m2 * -1/4 = -1
m2 = 4
So, using the general form, we have the equation as;
y = 4x + b
To get the value of b, we substitute the coordinates of the given point (3,-1)
-1 = 4(3) + b
-1 = 12 + b
b = -1-12
b = -13
So the equation is;
y = 4x - 13 which can be rewritten as;
4x-y = 13
4x4+4x3-9x2-x+2 = x-1
Answer:
x= 13/2
Step-by-step explanation:
multiply 4x4+4x3-9x2-x+2=x-1
calculate 16+12-18-x+2=x-1
move the terms 12-x=x-1
collect like terms calculate -x-x=-1-12
divide both sides -2x=-13
solution x=13/2

F f(x) = -2(x - 3)2 + 8
G f(x) = -2x2 + 12x - 10
H f(x) = -0.5(x - 3)2 + 2
J f(x) = -0.5x² – 3x - 6
9514 1404 393
Answer:
H f(x) = -0.5(x -3)² +2
Step-by-step explanation:
The quadratic opens downward, so the leading coefficient is negative. All answer choices agree on this.
The vertex (maximum point) is (3, 2). Choices F and H are written in vertex form. Choice F has a vertex of (3, 8); choice H has a vertex of (3, 2), so is a likely candidate.
When we look at the graph 1 unit right or left of the vertex, we see that it is about 1.5, that is, 0.5 units below the vertex. This 0.5 is the magnitude of the leading coefficient, which we already know is negative. The leading coefficient of -0.5 eliminates choices F and G.
So, choice H has the correct leading coefficient and the correct vertex.
Choice J can be eliminated by looking at the value for x=0. For J, it is -6, but we see the y-intercept of the graph is -2.5. This eliminates choice J.
The only viable choice is H.

Mia found the volume of a rectangular prism to be 840 mm3. As she was telling her father about it. she remembered that the base had a length of 10 mm and a width of 12 mm, but she could not remember the height maybe there is a way you can find it by going backwards . her father suggested. Can you help Mia find the height of her prism. Explain your solution.
Answer:
H = 7mm
Step-by-step explanation:
Height of Prism
So to calculate the height, multiply L · H · W. But since there is no height we will multiply what is given and then divide the volume by the product. For this case, the volume of the prism is 840 and its length is 10 and its width is 12. Multiply 10 and 12 then dividing 840 by 120. The height of the prism is 7.
Solve
Volume if the rectangular prism is given by the formula
V = L · H · W
Length, Height, Width of the prism
L = 10mm H = 12mm Volume = 840mm³
10 · 12 · h = 840
∴ 840 ÷ 120 = 7
H = 7mm

Answer:
Median without outlier should be 40
For the bottom questions, it should go:
Decreases the mean, does not change the median, does not change the mode
It's decreasing the mean because it goes from 44.7 to 39
Median w/ and without outlier is both 40
Mode also stays the same w/ or without the outlier, which is 96
Which of the following is an equation of the circle with a center at (-1,4) and a radius of 2√5 units? plss pahelp naman
A. x²+ y²+2x-8y-3=0
B. x²+y²-2x-8y+3=0
C. x²+y²+2x+8y-3=0
D. x²+y²-2x+8y+3=0
Answer:
Option A
Step-by-step explanation:
The standard form of an equation of a circle is represented by the formula [tex](x-h)^2+(y-k)^2 = r^2[/tex]. Remember that [tex](h,k)[/tex] is the center and [tex]r^2[/tex] is the radius squared.
So, the equation of the circle must be [tex](x+1)^2 +(y-4)^2 = 20[/tex]. Complete the square to change the form of the equations listed in the options and find the one that is equal.
Let's try this with option A. Move the constants to the right side, then use the completing the square method to place the equation in standard form:
[tex]x^2 + y^2 +2x -8y -3 = 0\\x^2 + y^2 +2x-8y = 3\\x^2 + 2x +y^2-8y = 3\\(x^2 +2x+1)+(y^2-8y +16)=3+1+16\\(x+1)^2 + (y-4)^2=20[/tex]
The end result matches with the equation determined before, so option A is the answer.

A monthly salary is $1622.31. It is given an increase of 3.8%. After the first increase, it receives a second increase of 6.2%. What is the new monthly salary after both increases? Round your answer to two decimal places. Do not put the $ sign in your answer or any units. Only put the number value for your answer.
Answer:
the new monthly salary after both increase is 1,788.37
Step-by-step explanation:
The monthly salary is 1,622.31
There is an increase of 3.8%
So, the salary after first increase is
= 1,622.31 × (1 + 3.8%)
= 1,683.96
Now there is a second increase of 6.2%, so the salary after second increase is
= 1,683.96 × (1 + 6.2%)
= 1,788.37
Hence, the new monthly salary after both increase is 1,788.37
The goal of the students in the club was to raise $500. They sold 43 flowerpots. By what amount did the students exceed their goal of raising $500?
Answer:
Exceeded by 145 dollars.
Step-by-step explanation:
First you multiply 15 by 43 because each pot costs 15 dollars and they sold 45.
Then you get the answer of 645 and the goal was 500 so that means you need to subtract to see how much they exceeded by.
Subtract 500 from 645 and you get the answer of 145.
So they exceeded 145 dollars.
