Fraction is written as:
1/2, 3/4, 5/6
Where 1, 3, and 5 are numerators and 2, 4, and 6 are denominators.
The ratio is written in the form a:b.
1:2 = 1/2
4:8 = 4/8 = 1/2
Fractions and ratios cannot have zero in the denominator.
This is true because if we have zero in the denominator the fraction becomes undefined.
Example:
1/0 = ∞
The ratio can not have zero in the denominator because we are comparing two units where neither one unit can be zero.
Fractions and ratios can be simplified in the same way.
This is true.
Example:
Fraction = 2/4 = 1/2
Ratio = 2:4 = 2/4 = 1/2
Fractions and ratios are different names for the same thing.
This is true.
Because ratio can be written as a fraction.
Example: 2:3 = 2/3
Some fractions and ratios can be written as mixed numbers.
This is not true
Fractions can be written as a mixed numbers.
Example:
5/2 = [tex]2\frac{1}{2}[/tex]
Ratios can never be written as a mixed number.

Given that f (x) = x help me plz
Answer:
Step-by-step explanation:
f(x) + g(x) = x^2 - 2x + x + 12
f(x) + g(x) = x^2 - x + 12
(f + g)( -1) = 1 + 1 + 12 = 14
f(x) - g(x) = x^2 - 2x - x - 12
f(x) - g(x) = x^2 - 3x - 12
(f + g)(-1) = (-1)^2 -(3)(-1) -12
(f + g)(-1) = 1 + 3 - 12

Laura received a $80 gift card for a coffee store. She used it in buying some coffee that cost $7.96 per pound. After buying the coffee, she had $56.13
left on her card. How many pounds of coffee did she buy?
Answer:
Step-by-step explanation:
Hi.
I can help.
First what we want to do is take what she had before spending any money and then take what she had after.
So :
$80.00
and
$56.13
Now to find how much she spent we can subtract these two numbers like so :
80.00 - 56.13
=
23.87
So now we know she spent a total of $23.87 on coffee in pounds.
Now if each pound of coffee costs $7.96 we can divide this into how much she spent $23.87 to find the total amount of pounds she bought for $7.96.
So:
23.87 / 7.96
=
About 3
She bought 3 pounds of coffee.
Hope this helps,

The price of an item yesterday was $120. Today, the price rose to $294. Find the percentage increase.
Answer:
145%.
Step-by-step explanation:
Given that the price of an item yesterday was $120, and today, the price rose to $294, in order to find the percentage increase, the following calculation has to be made:
120 = 100
294 = X
((294 x 100) / 120) = X
29,400 / 120 = X
245 = X
245 - 100 = 145
Therefore, the percentage increase of the product was of 145%.

Suppose that at Northside High, the number of hours per week that seniors spend on homework is approximately Normally distributed with a mean of 18.6 and a standard deviation of 6. We take a random sample of 36 seniors. What is the mean and standard deviation of the sampling distribution for the 36 students?
Answer:
The mean and standard deviation of the sampling distribution for the 36 students will be:
Mean = 18.6
Standard deviation = 6
Step-by-step explanation:
The mean and standard deviation of the sampling distribution is equal to the population mean and standard deviation respectively. The only difference is that the population mean and standard deviation are parameters or fixed values calculated from every individual in the population, while the sample mean and standard deviation are statistics. Statistics are calculated from only some of the individuals in a population. They are meant to represent or approximate the population parameters.

The sum of the measures of the angles of a triangle is 180. The sum of the measures of the second and third angles is five times the measure of the first angle. The third angle is 10 more than the second.
Answer:
first angle be 30°
second angle be 70°
third angle be 80°
Step-by-step explanation:
first angle be x
second angle be y
third angle be z
x+y+z=180
given, y+z = 5x; z=5x-y
also, z=y+10
5x-y = y+10
5x= 10+y+y = 10+2y
x= (10+2y)/5
x+y+z=180
(10+2y)/5 + y + y+10 = 180
(10+2y)/5 = 180 -2y -10
(10+2y)/5 = 170-2y
multiply both sides by 5
10+2y = 5(170-2y)
10+2y= 850-10y
2y+10y = 850-10
12y= 840
y= 840/12 = 70°
z=y+10 =70+10= 80°
5x= (10+2y) = 10+2(70) = 10+140= 150
x = 150/5 = 30°
can be used to compare changes from one period to another.
a) Decimals
b) Fractions
c) Percentages
d) Digits
Answer:
c) Percentages
Step-by-step explanation:
Percentages can be used to compare changes from one period to another.
In calculating a percentage change, either a percentage increase or percentage decrease, we must have both the new and old measurement of the specific quantity.
For example, let's find percentage increase of the number of students that joined a book club using the parameters below;
Original number of students = 32
New number of students = 36
We will calculate the increase using;
[tex] Increase = original \; number - new \; number [/tex]
Substituting the values, we have;
Increase = 36 - 32 = 4
[tex] Percentage \; increase = \frac{increase}{original \; number} * 100[/tex]
[tex] Percentage \; increase = \frac{4}{32} * 100[/tex]
[tex] Percentage \; increase = 0.125 * 100[/tex]
Percentage increase = 12.5%
Therefore, the number of students in the school club increased by 12.5%.

A truck is carrying passion fruit juice, cherry juice, and mango juice bottles in a ratio 1:2:7. If there are 34 cherry juice bottles, then how many nango juuce bottles are there?
Answer:
Step-by-step explanation:
We can solve this using a ratio. If there a 2 bottles of cherry in the ratio and there are 34 actual bottles of cherry, then the ratio is
[tex]\frac{ratio}{actual}:\frac{2}{34}[/tex]
In the ratio, we are told that the mix of bottles is 7 parts mango and we want to know how many actual bottles there are of mango. So filling in:
[tex]\frac{ratio}{actual} =\frac{2}{34} =\frac{7}{m}[/tex] and cross multiply to get
2m = 238 and
m = 119. There are 119 bottles of mango juice. And just for the record, there are 17 bottles of fruit juice.
Answer:
m = 119. There are 119 bottles of mango juice. there are 17 bottles of fruit juice.
Please only correct answer. don’t answer if you don’t know the answer, I don’t need to know that you don’t know
Answer:
f(x) = -0.5x - 2;
At x = 0, f(x) = -2
At x = 1, f(x) = -2.5
At x = 2, f(x) = -3
At x = 3, f(x) = -3.5
At x = 4, f(x) = -4
g(x) = (2^(x - 1)) - 5;
At x = 0, g(x) = -4.5
At x = 1, g(x) = -4
At x = 2, g(x) = -3
At x = 3, g(x) = -1
At x = 4, g(x) = 3
Step-by-step explanation:
First equation;
f(x) = -0.5x - 2
f(0) = -0.5(0) - 2 = -2
f(1) = -0.5(1) - 2 = -2.5
f(2) = -0.5(2) - 2 = -3
f(3) = -0.5(3) - 2 = -3.5
f(4) = -0.5(4) - 2 = -4
For the second equation;
g(x) = (2^(x - 1)) - 5
g(0) = (2^(0 - 1)) - 5 = 2^(-1) - 5 = -4.5
g(1) = (2^(1 - 1)) - 5 = 2^(0) - 5 = -4
g(2) = (2^(2 - 1)) - 5 = 2 - 5 = -3
g(3) = (2^(3 - 1)) - 5 = 4 - 5 = -1
g(4) = (2^(4 - 1)) - 5 = 3
