Answer:
Boys: 2/17
Girls: 4/17
Step-by-step explanation:
2 + 15 = 17 (to get the total number of boys in Sapphire's class)
4 + 13 = 17 (to get the total number of girls in the class)
The proportion is how many who are left handed over the total number of girls/boys. ^^
So, left-handed for boys = 2, which makes the proportion 2/17
And there are 4 left-handed girls, so the proportion is 4/17

3/5
7/10
13/20
Step-by-step explanation:
A rational number is a number that can be derived by dividing 2 whole numbers
1/2 = 0.5 0r 50%
3/4 = 0.75 75%
Between 50% and 75% are 51 - 74 which can be expressed as rational numbers
3/5 = 0.6
7/10 = 0.7
11/20 = 0.55
13/20 = 0.65

Prove: An even plus an odd
equals an odd.
(2m) + (2n + 1) = 2(m + [?] + [ ]
odd
Answers
Answer:
2(m + [n)] + [1]
Step-by-step explanation:
(2m) + (2n + 1) =
= 2m + 2n + 1
= 2(m + n) + 1
= 2(m + [n)] + [1]
The simplification of the expression would be equal to 2(m + [n)] + [1].
What is a simplification of an expression?Usually, simplification involves proceeding with the pending operations in the expression.
Like, 5 + 2 is an expression whose simplified form can be obtained by doing the pending addition, which results in 7 as its simplified form.
Simplification usually involves making the expression simple and easy to use later.
An even plus an odd equals an odd.
[tex](2m) + (2n + 1)\\= 2m + 2n + 1\\= 2(m + n) + 1\\= 2(m + [n)] + [1][/tex]

Could someone help me, please?
Answers
Answer:
33°
Step-by-step explanation:
<ACD =90-33 =57°
<DCB=<ACB - <ACD
=90° -57 =33°
In triangle ACD the only angle that has not been found is <ACD so you find it by adding 90+33 and subtracting from 180° to get 57°. <ACB =90° and <ACD = 57° ,the angle in question is<DCB which is part of< ACB. So to get <DCB you do 90°-57°=33°.
B = 180 - 90 - 33 = 57°
C in DCB tringle = 180 - 90 - 57 = 33°
So C in DCB triangle = 33°

Jenny runs a daycare center and charges $60 per day for each child. There are currently 50 children enrolled at the daycare. At a recent conference, Jenny was advised to lower her rates in order to stay competitive in her area. For each price decrease of $4 per day, the number of children enrolled at the center increases by two.
Write the equation that can be used to determine the number of price decreases, x, in dollars, for which the daycare center has a daily revenue of $2,800.
A.
(60 - 4x)(50 + 2x) = 2,800
B.
(60 + 4x)(50 - 2x) = 2,800
C.
(60 - 2x)(50 + 4x) = 2,800
D.
(60 + 2x)(50 - 4x) = 2,800

Camila is working two summer jobs, making $10 per hour lifeguarding and $6 per hour walking dogs. Last week Camila worked 5 more hours lifeguarding than hours walking dogs and earned a total of $114. Write a system of equations that could be used to determine the number of hours Camila worked lifeguarding last week and the number of hours she worked walking dogs last week. Define the variables that you use to write the system.
Answers
Let L = the numbers of hours lifeguarding
Let D = the number of hours walking dogs
Camila makes $10 per hour lifeguarding, so in L hours she will make 10L dollars. Camila makes $6 per hour walking dogs, so in D hours she will make 6D dollars. The total amount earned 10L+6D equals $114.
Since Camila worked 5 more hours lifeguarding than hours walking dogs, she worked more hours lifeguarding, so if we add 5 to the number of hours walking dogs, we will get the number of hours lifeguarding, meaning L equals D+5.
10L+6D=114
L=D+5

Step-by-step explanation:
Hi,
f(x) = (x - 1) - 3
The -1 is the 1 unit to the right (even though it's being subtracted, it's going to the right because it's embedded with the x)
And the -3 is not embedded with the x, meaning the function will move 3 units down.

the area is __ square units
Answers
Explanation:
So, what we need to do is to separate that triangle at the too from the rectangle.
Now we have two shapes.
Lets find the are of the triangle:
The height of the triangle is 7, which is perpendicular to the base.
The base is going to be also 20 because its the same length as the rectangle’s.
The formula for the are of a rectangle is
1/2 x Base x height (1/2 x 20 x 7) which is equal to 70 square units.
The area of the triangle is 100 square units (20 x 5)
We add the area of the shapes:
100 square units + 70 square units= 170 square units

Step-by-step explanation:
Given X= 58
N = 175.
P = 25% = 0.25.
[tex]P' = \frac{X}{N} = \frac{58}{175} = 0.3314\\Z = \frac{P'-P}{\sqrt{\frac{pq}{N} } }[/tex]

Sophie invested 5,000 into an account that will increase in value by 2.3% each year. Write a function to model this situation, then find the value of the investment after 15 years
Answers
Answer:
$6725
Step-by-step explanation:
Given data
Princiapal= $5000
Rate=2.3%
Time= 15years
The function that will model this situation is given as
A=P(1+rt)
The above function is a simple interest function
Substitute our data we can find the amount A
A=5000(1+0.023*15)
A= 5000(1+0.345)
A=5000(1.345)
A=5000*1.345
A=$6725
Hence the value of the investment after 15 years is $6725
