Answer:

Step-by-step explanation:
3/4 divided by 3/16
3/4 times 16/3
reduce
4
Answer: 4
Step-by-step explanation: do the brackets first. which is (1/2 * 3/8) to multiply these two together multiply numerator by numerator and denominator by denominator. Or, top * top / bottom * bottom
so we'd do 1*2 / 3*8. so it would give you 3/16.
now all we have left to do is divide 3/4 by 3/16.
to do this you can multiply by the reciprocal of the second value(3/16 will become 16/3)
now we have [tex]\frac{3}{4}[/tex] * [tex]\frac{16}{3}[/tex] you can cancel out each 3 to give you 1/4 * 16/1
and you can also divide both 16 and 4 by 4 (16/4=4)
this gives you a final equation of 1 * 4 for a final answer of 4

How do you find percentages?
Answer:
obtained number divided by total number multiply by 100%.
· Definition of Percentages
Mathematically, percentages are either numbers or ratios that are expressed as fractions of 100. They are usually denoted as "%" or simply "percent." They may be further represented as simple fractions or as decimal fractions. An example of a percentage is 65% or 65 percent. The term percentage was formed from two words, “per” and “cent.” Cent is a word with Latin and French origin that means "hundred," and "percent" means "per hundred." For example, 90 percent (or 90%) means 90 out of 100 while 50 percent (or 50%) means 50 out of 100 or half of a whole.
1. Determine the initial format of the number to be converted to a percentage
The number to be converted to a percentage can either be in the decimal or fraction format. A good example of a decimal number is 0.57, which may be the calculated ratio of the values you are comparing, while an example of a fraction is 3/20. The initial format will determine the next mathematical process to be carried out on the number.
2. Carry out a mathematical process on the number to be converted to a percentage
If the number to be converted to a percentage is a decimal number like 0.57, you may not need to do anything to it before you go to the next step. However, if it is a fraction like 3/20, you should first divide the numerator (3 in this case) by the denominator (20 in this case) to get a decimal number.
3. Multiply the result of the mathematical process by 100
If you are required to convert a decimal number like 0.57 to a percentage, you are to simply multiply it by 100. That is, 0.57 x 100 = 57. Therefore, 0.57 as a percentage = 57% or 57 percent. Another example of converting a decimal to a percentage is 0.03 x 100 = 3% or 3 percent.
However, if you are required to convert 3/20 to a percentage, you should divide 3 by 20 = 0.15. Then multiply 0.15 by 100 = 15% or 15 percent.
Another example is if you are to convert 5/10 to a percentage, you should divide 5 by 10 = 0.5. Then, multiply 0.5 by 100. Therefore, 0.5 x 100 = 50% or 50 percent.
m^ 2 + m − 90 factorize
Answer:
(m+10)(m-9)
Step-by-step explanation:
To factor this equation we want to find two numbers that multiply to -90 but also add/subtract to 1.
Those two numbers are 10 and -9 (10×-9=-90, 10-9=1)
Answer:
[tex](m-9)(m+10)[/tex]
Step-by-step explanation:
When you are given an expression in this format
[tex]ax^2+bx+c[/tex]
You must find two numbers that add up to b while the product is c.
You do trial and error to figure it out for your equation.
[tex]m^2+m-90[/tex]
Hmm... what two numbers add up to 1 and multiplied together equal -90.
Start off with pairs that can equal 90.
45 2
18 5
9 10
Ok, well 45 * 2 does equal 90 but 45 + 2 = 47and 45 + -2 = 43 but there's no way I can make it equal to 1. Next!
18 * 5 equals 90 but 18 + -5 = 13 and 18 + 5 = 23, I can just tell that there's no way I can make this equal to 1.
9 * 10 equals 90, 9 + 10 = 19 but 9 + -10 = -1. Now, that's interesting, We have -1 but we need 1. All we have to do is flip the order. 10 + -9 = 1. And -9 * 10 = -90, PERFECT!
Now use the two numbers and put it in factored form.
[tex](m-9)(m+10)[/tex]

Step-by-step explanation:
.......................
Answer:
Where's the diagram?
Step-by-step explanation:
On average, a person’s heart beats about 4.2×107 times per year. There are about 7,600,000,000 people in the world. Use this data to approximate the number of heartbeats for all the people in the world per year. Expressing your answer in scientific notation in the form a×10 b , what are the values of a and b ?
A person heart beats is 4.2 x 10∧7
there are 7,600,000,000= 7.6 x 10∧9
the heartbeats for all the people here on earth= 4.2 x 10∧7 x 7.6 x 10∧9
choosing like terms
4.2 ×7.6×10∧7×10∧9
31.92x10∧(7+9)
31.92×10∧16
a=31.92
b=16
Answer:
[tex]3.192*10^1^7[/tex]
Step-by-step explanation:
To find this value, multiply the two values given:
4.2x10^7 = 4.2 x ( 10 x 10 x 10 x 10 x 10 x 10 x 10) = 42000000
42000000 x 7600000000 = 319200000000000000
Then convert 319200000000000000 into scientific notation:
319200000000000000 = 3.19200000000000000
Cut off all the zeroes and I moved the decimal 17 places to the left, so the exponent will be positive:
[tex]3.192*10^1^7[/tex]
find area and perimeter
Answer:
Area = 18×(6+9) + (11×9)
= (18×15) + 99
= 270 + 99
= 369m²
Perimeter = 2(18+11) + 2(15)
= 2(29) + 30
= 58 + 30
= 88m
Determine the value of y
Answer:
C
Step-by-step explanation:
Because [tex]y^{\circ}[/tex] and [tex]134^{\circ}[/tex] both lie on a straight line, they sum to [tex]180^{\circ}[/tex].
So, [tex]y+134=180[/tex].
We can subtract [tex]134[/tex] from both sides of the equation to get [tex]y=46[/tex].
So, the answer is [tex]\boxed{C}[/tex] and we're done!

The price of an item is $45.00. After a discount, the price is $38.25. What is the percent of the discount?
Answer correctly and I will give brainliest
Answer:
=15
Step-by-step explanation:
45-x% *45=38.25
(-45) x/100=38.5-45
(-45)x/100=(-6.75)
x=6.75 * 100/45
=15
The percent of the discount is 15.
It is required to find the percent of the discount.
What is percentage?A part of a whole expressed in hundredths a high percentage of students attended. Also the result obtained by multiplying a number by a percent the percentage equals the rate times the base.
Given:
Let the discount percent be x%
When the price of $45 is reduced by x%, we get $38.25.
So,
45 − x % ∗ 45 = 38.25
− 45 x /100 = 38.25 − 45
− 45 x /100 = − 6.75
x = 6.75 ∗ 100 /45
x= 15
Therefore, the percent of the discount is 15.

The Swiger family recycles about 15 pounds of waste a week. This is 2/5 of the total waste a week. How many pounds of waste does the family produce each week? (Step by step explanation)
Answer: 37.5 lb/wk
Step-by-step explanation:
Let X be the total amount of waste. We are told that (2/5) of X is 15 lb/wk.
(2/5)X = 15 lb/wk
X = (5/2)*(15lb/wk)
X = (75/2) il/wk
X = 37.5 lb/wk

Evaluate the function.
Find the equation of the line.
A line that is parallel to the graph of 2x+3y=5 and contains the point (3,1)
Answer:
2x + 3y = 6
Step-by-step explanation:
The equation of a line in slope- intercept fprm is
y = mx + c ( m is the slope and c the y- intercept )
Given
2x + 3y = 5 ( subtract 2x from both sides )
3y = - 2x + 5 ( divide terms by 3 )
y = - [tex]\frac{2}{3}[/tex] x + [tex]\frac{5}{3}[/tex] ← in slope- intercept form
with slope m = - [tex]\frac{2}{3}[/tex]
Parallel lines have equal slopes, then
y = - [tex]\frac{2}{3}[/tex] x + c ← is the partial equation
To find c substitute (3, 1 ) into the partial equation
1 = - 2 + c ⇒ c = 1 + 2 = 3
y = - [tex]\frac{2}{3}[/tex] x + 3 ( multiply through by 3 to clear the fraction )
3y = - 2x + 6 ( add 2x to both sides )
2x + 3y = 6 ← equation of parallel line
