the sales of a particular brand of children’s athletic shoes rose from 6900000 to 7500000. find the percent of increase in sales. round to the nearest tenth of a percent if necessary
Answer:
6900000 + (6900000 * x) = 7400000
This equation is telling us 6900000 plus 6900000 times a specific percent will get you 7400000, which is what you want.
6900000 + (6900000 * x) = 7400000
6900000 + 6900000x = 7400000
Subtract 6900000 from both sides.
6900000x = 500000
Divide both sides by 6900000
x = 0.0724637681, or .07 when rounded to the nearest tenth.
convert .07 to a percentage by moving the decimal point two places to the right.
.07 = 7%
The sales of the children's athletic shoes rose about 7%

11693.4
417.6
2923.3
153.9
2.
Answer:
2923.34 in^3
Step-by-step explanation:
Volume = Pi x (r) ^2 x height
PI =3.14,
, R = 7inch (d =radius /2 >> 14/2)
H =19 inch
Volume = 3.14 x 49in^2 x 19 inch
= 2923.34 in^3
In terms of power is the volume of the sphere
Work Shown:
The diameter is 60 feet, so the radius is half that at 60/2 = 30 feet.
Plug r = 30 into the formula below and simplify
V = (4/3)*pi*r^3
V = (4/3)*pi*(30)^3
V = (4/3)*pi*27000
V = (4/3)*27000*pi
V = 36000pi
Answer:
[tex]36000\pi ft^3[/tex]
Step-by-step explanation:
[tex]V=\frac{4}{3} \pi r^3\\=\frac{4}{3} \pi 30^3\\=113097.336ft^3\\[/tex]
In terms of Pi this equals

Julie and Ryan want to refinish the gym floor at the community center. The rectangular floor is 15.2 meters wide and 25.6 meters long. If each gallon of polyurethane covers about 180 square meters, how many gallons should they buy?
Answer:
3 gallons
Step-by-step explanation:
We need to find the area of the floor first:
25.6*15.2=389.12
Now we divide the surface area by gallons of polyurethane.
389.12÷180=2.161777777777777777777777777777....≈2.16 gallons needed. But OH WAIT! You can't buy 0.16 of a gallon so you need 3 gallons.

Tony will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $38 and costs an additional $0.13 per mile driven
The second plan has an initial fee of $49 and costs an additional $0.09 per mile driven
for what amount of driving do the two plans cost the
What to the cout when the two plans cout the same?
Answer:
He need to cover 275 miles for same cost for both plans
Step-by-step explanation:
Let x be the no. of miles
Case 1 :
Initial fee = $38
Additional cost of 1 mile = 0.13
Additional cost of x miles = 0.13x
So, total cost = 38+0.13x
Case 2 :
Initial fee = $49
Additional cost of 1 mile = 0.09
Additional cost of x miles = 0.09x
So, total cost = 49+0.09x
Now we are supposed to find amount of driving do the two plans cost the same
So, 38+0.13x=49+0.09x
0.13x-0.09x=49-38
0.04x=11
[tex]x=\frac{11}{0.04}[/tex]
x=275
Hence he need to cover 275 miles for same cost for both plans

Plez halp with question bc im smol brain
Answer:
B. y= 2x–15
Step-by-step explanation:
The equation that represents the line that passes through the points (8, 1) and (10,5) is y= 2x–15
"x" is found on the left hand side of the bracket and "y" is found on the right hand side of the bracket :)
(8, 1) and (10, 5)
x in the first bracket is 8 and x in the second bracket is 10.
y in the first bracket is 1 and y in the second bracket is 5.
When this equation is applied to find the value for y we get:
y= 2x-15
y= 2(8)-15
y= 16-15
y= 1
y= 2x-15
y= 2(10)-15
y= 20-15
y= 5
We got back the values of y and this means that the equation was correctly chosen and the answer is correct :)
PLEASE HELP IM TRYING TO PASS MY FINIALS!
Answer:
There is no real solution
Step-by-step explanation:
If you are finding the square root of a number, it cannot be negative. No number can be multiplied by itself to get a negative number. Negative numbers multiplied with themselves make a positive number. Positive numbers are obviously going to stay positive. Therefore there is no square root of -9
write an equation in standard form for the line that passes through (3,-1) and (-5,-3)
Answer:
y = 1/4x - 1.75
Step-by-step explanation:
standard form is y = mx + b
to get m you need to calculate the slope between the given points
m= (y1-y2)/(x1-x2)
m = (-1 - (-3))/(3 - (-5)) = 2/8 = 1/4
now you need to find the constant b by plugging in one of your points
y = 1/4x + b
-1 = 1/4(3) + b
b = -1 - (3/4)
b = -7/4 or -1.75
Answer:
0 = x - 4y - 7
Step-by-step explanation:
Moving from (-5, -3) to (3, -1), we see that x (the run) increases by 8 and y (the rise) incrases by 2. Thus, the slope of the line connecting these two points is m = rise / run = 2/8, or 1/4.
Use the slope-intercept form of the equation of a straight line first:
y = mx + b becomes -1 = (1/4)(3) + b, or (after multiplying all three terms
by 4) -4 = 3 + 4b. Then 4b = -7, and b = -7/4.
Then the desired equation is y = (1/4)x - 7/4, or
4y = x - 7, or
0 = x - 4y - 7. This is the desired equation in standard form.
Two classmates, Aisha and Brandon, want to attend two school activities
over the coming weekend. They have one parking pass between them. The
probabilities that the classmates will attend each event are shown in the
table.

0.71
Probability of attending
the Saturday activity
Probability of attending
the Sunday activity
0.68
0.89
They decide to let the person more likely to attend both events have the
parking pass. Assuming that attendance at one activity is independent of
attendance at the other, who is more likely to attend both activities?
A. Aisha. She has a 0.61 probability of attending both activities.
B. Brandon. He has a 0.71 probability of attending both activities.
C. Brandon. He has a 0.63 probability of attending both activities.
Answer:
C. Brandon. He has a 0.63 probability of attending both activities.
Step-by-step explanation:
Probability of attending Probability of attending
the Saturday activity the Sunday activity
Aisha 0.90 0.68
Brandon 0.71 0.89
Given that attendance at one activity is independent of attendance at the other, the probability that Aisha attends both activities is: 0.9*0.68 = 0.61, and the probability that Brandon attends both activities is: 0.71*0.89 = 0.63
Brandon has a 0.63 probability of attending both activities.
The correct option is (C).
What is probability?Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event.
Probability of attending Probability of attending
( Saturday) ( Sunday )
Aisha 0.90 0.68
Brandon 0.71 0.89
As, attendance at one activity is independent of attendance at the other activity.
P( Aisha attends both activities)
=0.9*0.68
= 0.61,
P(Brandon attends both activities)
= 0.71*0.89
= 0.63
Hence, Brandon. He has a 0.63 probability of attending both activities.

A cylinder has a base diameter of 8 centimeters and a height of 7 centimeters.what is its volume in cubic centimeters,to the nearest tenths place
The volume of the cylinder is approximately 351.9 cubic centimeters.
What is a cylinder?A cylinder is a 3-D figure that has a radius and a height.
The volume of a cylinder is given as πr²h.
Example:
The volume of a cup with a height of 5 cm and a radius of 2 cm is
Volume.
= 3.14 x 2 x 2 x 5
= 62.8 cm³
We have,
The volume of a cylinder can be calculated using the formula:
V = πr²h,
where r is the radius of the base and h is the height.
Since the base diameter is given as 8 centimeters, the radius is half of that or 4 centimeters.
Substituting these values into the formula, we get:
V = π (4 cm)² (7 cm)
V ≈ 351.86 cm³
Rounding this answer to the nearest tenth gives a final answer of V ≈ 351.9 cm^3.
Therefore,
The volume of the cylinder is approximately 351.9 cubic centimeters.

Pack 2: 12 X 300 g cans for $24.99
Pack 3: 9 X 400 g cans for $25.99
Pack 4:6 X 1 kg can for $38.50
Which of the following shows the packs ordered from best to worst buy? Select the correct
answer A, B, C or D.
A 4213
B 3214
C 4123
D 2134
Answer:
C. 4123.
Step-by-step explanation:
We calculate the cost of a gram of cat food for each package.
Pack 1: Cost of 1 gram = total cost / number of grams
= 39.99 / (24 * 250)
= $0.00665 '
Pack 2: The cost is 24.99 / (12 * 300)
= $0.00694.
In a similar way
Pack 3: The cost is $ 0.0722
Pack 4: The cost is $0.00642 .
So the answer is
