Answer:
87.5 percent
Step-by-step explanation:
80 passed the first, 70 passed the second. 7/8 passed both. 7/8 as a percentage is 87.5.
Answer:
C. 87.5%
Step-by-step explanation:
[tex]P(A|B)[/tex]
this is what you are trying to find.
P(A | B) can be found by dividing the percentage who passed both, by the percentage who passed the first.
70/80 = 0.875
multiply by 100 to get percentage instead of decimal

A county fair charges $9.00 for admission and $2.50 per ride. If Latisha spent $49 on admission and rides, how many rides did Latisha ride?
Answer:
Latisha rode 16 rides
Step-by-step explanation:
Look at picture attached. Have a blessed night!
Just slope intercept formula (y=mx+b). X represents the number of rides so you will need to myltiply that by $2.50. $9 is a one time fee so that would be of the b of the equation. That all equals the total Latisha piaid, $49. Then solve like so.

Find the volume of a right circular cone that has a height of 13.1 in and a base with a diameter of 5.7 in
Answer:
Step-by-step explanation:
1) Divide the diameter in half to make the radius, which equals 2.85 as r.
2) Plug in the radius(r) and height(h) with the correct numbers.
3) Simply solve
V = π(2.85)² × 13.1 ÷ 3
V= 25.52 × 13.1 ÷ 3
V= 334.312 ÷ 3
V= 111.4373+

Answer:
no
Step-by-step explanation:
We want to compare the pot holder hole dimension to the pot dimension. The hole diameter is the overall pot holder diameter less the wall thickness on either side:
hole diameter = (20 1/5) -2(1 2/7) = 20 -2(1) +1/5 -(2)(2/7)
= 18 +(1/5 -4/7) = 18 +(7 -20)/35 = 18 -13/35
= 17 22/35 . . . . cm
We want to compare this to 17 4/5. We can do that by using a common denominator for the fractions.
17 4/5 = 17 + (4/5)(7/7) = 17 28/35 . . . . cm
The pot has a diameter of 17 28/35 cm; the pot holder has a hole diameter of 17 22/35 cm, so the hole is smaller than the pot.
The pot will not fit into the plant pot holder.
_____
You can use your calculator to find the free space around the pot by computing ...
20 1/5 -2(1 2/7) -17 4/5 = free space = -6/35 . . . . cm
Negative space means the pot is larger than the hole.

Find the domain over which the function y = x + 6x is monotonic increasing.
Answer:
x > -3
[tex]\sf (-3, \infty)[/tex]
Step-by-step explanation:
Domain: input values (x-values)
Monotonic increasing: always increasing.
A function is increasing when its graph rises from left to right.
The graph of a quadratic function is a parabola. If the leading term is positive, the parabola opens upwards. The domain over which the function is increasing for a parabola that opens upwards is values greater than the x-value of the vertex.
Vertex
Standard form of quadratic equation: [tex]\sf y=ax^2+bx+c[/tex]
[tex]\textsf{x-value of vertex}=\sf -\dfrac{b}{2a}[/tex]
Given function:
[tex]\sf y=x^2+6x[/tex]
Therefore, x-value of function's vertex:
[tex]\sf \implies x= -\dfrac{6}{2}=-3[/tex]
Final Solution
The function is increasing when x > -3

How many liters of fruit punch did Wes make?
Answer:

10. Ryan inherited land from his grandfather. He decided to sell the land for $160,000, then place
the money in a new account that earns 1. 2% interest compounded bimonthly. How much
interest will he have earned after 30 years?
The amount of interest Ryan would earn at the end of 30 years given the interest rate is $69,250.27.
What is the interest rate on the new account?When an account earns an interest that is compounded bimonthly, it means that it earns an interest every 2 months.
The formula that can be used to determine the interest earned is:
Future value - amount deposited
FV = P (1 + r)^nm
FV = Future value P = Present value R = interest rate = 1.2/6m = number of compoundingN = number of yearsFV = 160,000(1.002^180) = $229,250.27
Interest = $229,250.27 - $160,000 = $69,250.27

Traveling at a speed of 12 mph, Jen biked home in 20 minutes. What was Jim's speed
if he biked the same distance in 15 minutes?
The speed of Jim if he biked the same distance in 15 minutes is 16 mph
What is speed ?Speed is the distance covered at a particular time. Therefore,
speed = distance / time
The distance in the first journey can be calculated as follows:
speed = 12 mph
time = 20 minutes = 0.3333 hours
12 = x / 0.333
distance = 0.333 × 12 = 3.9996 miles
Therefore, the speed of Jim if he biked the same distance in 15 minutes can be calculated as follows:
15 minutes = 0.25 hours
speed = 3.9996 / 0.25
speed = 15.9984
speed = 16 mph

What is the area of the figure?
Answer:
88
Step-by-step explanation:
We can divide this into 3 shapes, a square, rectangle, and triangle.
Let's solve the area of each of these shapes and add them all up.
First, let's solve the square.
We know that one side is 4 ft so that means that the other side is also 4ft.
4*4=16
Our area of the square is 16ft^2
Let's solve the rectangle next,
Its length is 12ft and its width is 4ft.
12*4=48
So the rectangle area is 48ft^2
Now for the triangle
Remember that area of a triangle is a=hb/2
Our height is 12 ft and our base is 4ft
12*4=48
48/2=24
Triangle is 24ft^2
That means that we can add them all up
24+48+16=88
88ft^2 or 88
Wilma loves to run she ran 1 hour and 15 minutes 3 days this week
If Wilma ran 1 hour 15 minutes and 3 days this week, the number of minutes she ran in total is 4395 minutes.
How to converts hours, days to minutes
She loves to run and she ran 1 hour and 15 minutes 3 days this week. Therefore, the total time in minutes she ran can be calculated as follows:
1 hour = 60 minutes
1 days = 24 hours
3 days = 72 hours
Therefore,
1 hours = 60 minutes
72 hours = 4320 minutes

Drag the measurements to the containers to show equal length.
The measurements that show equal length is 15 yd and 540 in, 195 ft and 2340 in, 5280 yd and 15840 ft
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
1 ft = 12 in; 1 yd = 3 ft and 1 yd = 36 in.
Hence:
15 yd = 15 yd * 36 in per yd = 540 in
195 ft = 195 ft * 12 in per ft = 2340 in
5280 yd = 5280 yd * 3 ft per yd = 15840 ft
