There are 60 calico cats at the animal shelter if this represents 30% of the cats in the shelter how many total cats are there
Answer: 200 cats in total
Step-by-step explanation:
60 calico cats represents 30% of the total cat population in the shelter.
That means that if we find 30% of the total number of cats, the number we will get is 60.
Assuming the total is x, representing this in equation form makes it:
x * 30% = 60
x = 60 / 30%
x = 200 cats in total

calculate the height/base
So basically, You know you need a missing Base or height and you have the Area and The height or the base so in this case
A=Area
B=Base
H=Height
So, A divided by B-H gets B or H.
1= 12 height
2= 5 base
3= 8 height

1/3(6z+7.2)=0.5(8z+2)-0.4
A z=0.8
B z=0.9
C z=2.8
D z=3.6
please help
Answer:
B z = 0.9
Step-by-step explanation:
1/3(6z + 7.2) = 0.5(8z + 2) - 0.4
Multiply both sides by 6.
12z + 14.4 = 24z + 6 - 2.4
-12z = -10.8
z = 0.9

Which of these contexts describes a situation that is unlikely?
O Rolling a 1 on a standard six-sided die, numbered from 1 to 6.
O Spinning a spinner divided into four equal-sized sections colored red/green/yellow/blue and landing on red or yellow or green or blue.
O Winning a raffle that sold a total of 100 tickets if you bought 9o tickets.
OReaching into a bag full of 10 strawberry chews and 10 cherry chews without looking and pulling out a strawberry or a cherry chew.
Answer:
The first one
Step-by-step explanation:
This is because all the other ones there is a likely chance that you will get them. While the first one it is less of a chance that you will role a die and land on a one. It is a 1 out of 6 chance
The situation which is unlikely is rolling a 1 on a standard six-sided die, numbered from 1 to 6
What is Probability?The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
Probability = number of desirable outcomes / total number of possible outcomes
The value of probability lies between 0 and 1
Given data ,
a)
Rolling a 1 on a standard six-sided die, numbered from 1 to 6
Probability P ( A ) = 1/6
P ( A ) = 0.1667
b)
Spinning a spinner divided into four equal-sized sections colored red/green/yellow/blue and landing on red or yellow or green or blue
Probability P ( A ) = 1
P ( A ) = 1
c)
Winning a raffle that sold a total of 100 tickets if you bought 90 tickets.
Probability P ( A ) = 90/100
P ( A ) = 0.9
d)
Reaching into a bag full of 10 strawberry chews and 10 cherry chews without looking and pulling out a strawberry or a cherry chew.
Probability P ( A ) = 10/20
P ( A ) = 0.5
Hence , the unlikely event is Rolling a 1 on a standard six-sided die, numbered from 1 to 6

Solve for x (Geometry)
Answer:
x = 18[tex]\sqrt{2}[/tex]
Step-by-step explanation:
The middle line divides the 90° angle in half meaning your triangles are isosceles triangles. Recall that an isosceles triangle has sides that are the same length.
Using pythagorean theorem a² + b² = c², you can solve for x
18² + 18² = x²
x² = 648
x = 18[tex]\sqrt{2}[/tex]

How many flowers, spaced every 4 in., are needed to surround a circular garden with a 200-ft radius? Use 3.14 for π.
Find the circumference of the circle:
Circumference = 2 x r x pi
Circumference = 2 x 200 x 3.14
Circumference = 1,256 feet.
4 inches/ 12 inches per foot = 0.333 ft.
Divide the circumference by the spacing:
1255/0.333 = 3,768
You will need 3,768 flowers

Find M please in this Geometry question.
Answer:
m = 8
Step-by-step explanation:
As we can see we have two similar triangles
These are triangles FDH and GEF
mathematically, when two triangles are similar, the ratio of their corresponding sides are equal;
Thus;
DH/DF = EG/EF
12/15 = m/10
15 * m = 12 * 10
15 m = 120
m = 120/15
m = 8

Problem: Jessica ordered a pizza. One-half of the pizza had pepperoni only, one-sixth of the pizza had mushrooms, and the rest of the pizza was cheese only. What fraction of the pizza was cheese only?
Answer:
1/3 of the pizza
Step-by-step explanation:
Number of pizza ordered = 1
pepperoni only part = One-half of the pizza = 1/2 of the pizza
Mushrooms part = one-sixth of the pizza = 1/6 of the pizza
Cheese only part = x
Total pizza = pepperoni only part + Mushrooms part + Cheese only part
1 = 1/2 + 1/6 + x
1 = (3+1) /6 + x
1 = 4/6 + x
1 - 4/6 = x
x = 1 - 2/3
= (3-2) / 3
x = 1/3 of the pizza
Cheese only part = x = 1/3 of the pizza

Power usage is measured in kilowatt-hours, kWh. After 7 a.m., the power usage on a college campus increases at a rate of 21% per hour. Prior to 7 a.m., 15,040 kWh have been used. The university has a daily goal to keep their power usage less than or equal to 100,000 kWh.
Which of the following inequalities can be used to determine the number of hours, t, after 7 a.m. when the power usage on campus will be less than or equal to 100,000?A.
15,040(0.79)t ≤ 100,000
B.
15,040(1.79)t ≤ 100,000
C.
15,040(1.021)t ≤ 100,000
D.
15,040(1.21)t ≤ 100,000
Answer:
D. 15,040(1.21)t ≤ 100,000
Step-by-step explanation:
The 15,040 is the prior electricity, and it increases by .21 per hour, and you don't want 100,000
To make an equation, use the simple interest formula (same concept)
Total = Amount(1 + rate) time
fill it out
100,000 >= 15,040(1.21)t
This equation is the same as D so D is the answer
