Answer:
166 square units
Step-by-step explanation:
Let’s find the area of the shapes that in the net.
First, we can see two of the triangles have a base of 2 and a height of 13. The formula for surface area of a triangle is bh÷2. (13x2)÷2=13. Since there are two triangles, we multiply 13 by 2 and get 26.
Second, we can see two of the triangles have a base of 10 and a height of 12. (10x12)÷2=60. Since there are two triangles, we multiply 60 by 2 and get 120.
Third, we can see a rectangle has a base of 10 and a height of 2. The formula for surface area of a rectangle is bh. 10x2=20.
Last, we add up all the areas:
20+120+26=166.

Step-by-step explanation:
Converting 0.632 to a fraction, Step-by-Step
Step 1:
The first step to converting 0.632 to a fraction is to re-write 0.632 in the form p/q where p and q are both positive integers. To start with, 0.632 can be written as simply 0.632/1 to technically be written as a fraction.
Step 2:
Next, we will count the number of fractional digits after the decimal point in 0.632, which in this case is 3. For however many digits after the decimal point there are, we will multiply the numerator and denominator of 0.632/1 each by 10 to the power of that many digits. For instance, for 0.45, there are 2 fractional digits so we would multiply by 100; or for 0.324, since there are 3 fractional digits, we would multiply by 1000. So, in this case, we will multiply the numerator and denominator of 0.632/1 each by 1000:
\frac{0.632 × 1000}{1 × 1000} = \frac{632}{1000}
1×1000
0.632×1000
=
1000
632
Step 3:
Now the last step is to simplify the fraction (if possible) by finding similar factors and cancelling them out, which leads to the following answer:
\frac{632}{1000} = \frac{79}{125}
1000

Gregory(g) is 20 years older than his cousin Mark(m). Mark is 6 years younger than his
sister Louanne(L). Write an expression to represent the sum of their ages.
Answers
An expression to represent the sum of their ages is as follows.
g = 14 + L
How do you figure up the total age?If the ratio of the ages of X and Y is p:q and their sum is X, then the following formula can be used to calculate Y's age: Age of Y = Y/Total Ages x Total Ratios. Age of Y = (p+q) q x A.
According to the given information:Assume that L is Louannel's sister's age, m is Mark's age, and g is Gregory's age.
Gregory's age difference with his cousin Mark, who is 20 years older (m).
∴ g = 20 + m .............(1)
Also given that Mark is 6 years younger than his sister Louanne(L)
∴ m = L - 6 ............(2)
Now, substituting m = L - 6 from (2) in (1),
∴ g = 20 + L - 6
∴ g = 14 + L

You are planning to sell ice cream cones for a school sporting event . You plan to sell 300 ice cream cones. Before selling the ice cream, you give a survey to determine what flavors to sell. The results are below.
• 10% - Mint
• 25% - Strawberry
• 15% - Chocolate chip
• 50% - Vanilla
Based on the survey results, how much of each flavor will you sell at the sporting event
Answers
Answer: Based on the survey results, we can calculate the number of ice cream cones to sell for each flavor by multiplying the percentage of the flavor by the total number of ice cream cones to be sold.
Mint: 10% of 300 ice cream cones = 0.1 * 300 = 30 ice cream cones
Strawberry: 25% of 300 ice cream cones = 0.25 * 300 = 75 ice cream cones
Chocolate chip: 15% of 300 ice cream cones = 0.15 * 300 = 45 ice cream cones
Vanilla: 50% of 300 ice cream cones = 0.5 * 300 = 150 ice cream cones
So, based on the survey results, you should sell 30 ice cream cones of Mint flavor, 75 ice cream cones of Strawberry flavor, 45 ice cream cones of Chocolate chip flavor, and 150 ice cream cones of Vanilla flavor.
It's worth mentioning that the sum of the percentages provided, 10+25+15+50 = 100%. Which means that it is a proper survey and the total number of ice cream cones you expect to sell is equal to the survey results.
Step-by-step explanation:
Based on the survey results flavors sold at the sporting event are, 30 mint ice creams, 75 Strawberry icecreams, 45 Chocolate chip icecreams, and 150 Vanilla icecreams.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
The number of different types of ice creams can be obtained as follows,
10% - Mint.
= (10/100)×300.
= 30.
25% - Strawberry.
= (25/100)×300.
= 75.
15% - Chocolate chip.
= (15/100)×300.
= 45.
50% - Vanilla.
= (50/100)×300.
= 150.

Miss Wade's science class of 20 students is going on a field trip to the zoo. Each student will also take a train ride around the zoo. Mr. Sexton's class of 25 students is going on a field trip to the state park and will take a canoe trip. Admission to the zoo is twice that of the state park's entry fee as shown in the table. Each group will spend the same total amount of money.
Answers
The admission fee for the zoo and for the state park is given as follows:
Zoo: $13.State park: $6.5.How to model the situation?For the zoo, the costs are divided as follows:
Admission: 2x per student.Train ride: $3.25 per student.20 students are going to the zoo, hence the total cost spent at the zoo is given as follows:
20(2x + 3.25) = 40x + 65.
For the state park, the costs are divided as follows:
Admission: x per student.Train ride: $6.50 per student.25 students are going to the state park, hence the total cost spent at the state park is given as follows:
25(x + 6.50) = 25x + 162.50.
The costs spent at both parks are the same, hence the value of x can be obtained as follows:
40x + 65 = 25x + 162.5
15x = 97.5
x = 97.5/15
x = 6.5.
Hence the admission fees are given as follows:

0.143
B.
0.286
C.
0.429
D.

Answers
Therefore , the solution of the given problem of probability comes out to be P =0.286(approx).
Define probability.Probability is the likelihood or potential for something to event. For instance, there is only one way to get a head and a total of two possible outcomes, hence the probability of flipping a coin and getting heads is 1 in 2. (a head or tail). P(heads) must equal 12. Classical: (equally likely results) (equally probable outcomes) S, the sample location (the collection of all distinct outcomes that could occur), Definition of Relative Frequency and Subjective Probability.
Here,
Given : S = {9,10,11,12,13,14,15}
If A is a subset of S, A could be {14,15}.
If a subset A represents the complement of spinning a number greater than 13, its sample space is A = {14,15}.
Thus,
To find the probability that it will land on number greater than 13
P = likelihood of event / total no of events
=> P = 2/7
=> P = 0.2857
=> P =0.286(approx)
Therefore , the solution of the given problem of probability comes out to be P =0.286(approx).

Answers
Answer:
∠x = 60°
Step-by-step explanation:
first:
∠a = 60° was given
the sides on each side of ∠a are equal so their opposite angles are equal also.
The sum of the interior angles of any triangle is 180°
The angles opposite ∠a are (180° - 60°)/2 = 60° each
Second:
∠b = 60° was given
so the angles opposite ∠b are also 60° each
Third:
the 2 angles opposite x are both 60° each because they are both vertical angles to 60°
That leaves ∠x to be 180° - 60° - 60° = 60°

During the summer holidays sarah earns pocket money by mowing lawn. She can mow 6 lawns in 1 1/2 and clean the pool in one-sixth of an hour
Answers
Answer:
It will take Sarah 2 1/2 hours to mow 10 lawns
It will take Sarah 1 2/3 hours to clean 10 pools
Step-by-step explanation:
During the summer holidays, Sarah earns pocket money by mowing the lawn. She can mow 6 lawns in 1 1/2 hour and clean a pool in one-sixth of an hour. How long does Sarah take to clean 10 pools and 10 lawns?
Number of lawns : Time to mow lawns = 6 : 1 1/2
= 6 : 3/2
Number of lawns : Time to mow lawns = 10 : x
6 : 3/2 = 10 : x
6 ÷ 3/2 = 10/x
6 * 2/3 = 10/x
12/3 = 10/x
Cross product
12 * x = 3 * 10
12x = 30
x = 30/12
x = 2 6/12
x = 2 1/2 hours
It will take Sarah 2 1/2 hours to mow 10 lawns
Number of pools cleaned : time taken = 1 : 1/6
Number of pools cleaned : time taken = 10 : x
1 : 1/6 = 10 : x
1 ÷ 1/6 = 10/x
1 * 6/1 = 10/x
6 = 10/x
Cross product
6 * x = 10
6x = 10
x = 10/6
x = 1 4/6
x = 1 2/3 hours
It will take Sarah 1 2/3 hours to clean 10 pools
