Estimate the percent using decimals.
48% of 400
Step-by-step explanation:
getcalc.com's fraction to decimal calculator to find what's an equivalent decimal for the fractional number 48/400.
50/400 0.125 12.5%
49/400 0.1225 12.25%
48/400 0.12 12%
47/400 0.1175 11.75%
Answer:
fraction to decimal calculator to find what's an equivalent decimal for the fractional number 48/400.
0.12 is a decimal and 12/100 or 12% is the percentage for 48/400.
Step-by-step explanation:
A fraction consists of two numbers and a fraction bar:
48/400
The number above the bar is the numerator: 48
The number below the bar is the denominator: 400
Divide the numerator by the denominator to get fraction's value:
Val = 48 ÷ 400
Introduction. Percent, p%
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% = p/100 = p ÷ 100.
Calculate fraction's value.
Divide the numerator by the denominator to get fraction's value:
48/400 =
48 ÷ 400 =
0.12
Note:
100/100 = 100 ÷ 100 = 100% = 1
Multiply a number by the fraction 100/100,
... and its value doesn't change.
Calculate the percent value:
0.12 =
0.12 × 100/100 =
(0.12 × 100)/100 =
12/100 =
12%;

Find the measure of the given angles. Show work!!
Answer:
m∠A = 45⁰
m∠B = 75⁰
Step-by-step explanation:
Given question 4;
m∠A = x + 51
m∠B = 81 + x
m∠C = 60⁰
The value of the missing angles can be determined by the finding the value of x first;
m∠A + m∠B + m∠C = 180⁰ (sum of angles in a triangle)
(x + 51) + (81 + x) + 60⁰ = 180
(x + x) + (51 + 81 + 60) = 180
2x + 192 = 180
2x = 180 - 192
2x = -12
x = -12/2
x = -6
Thus, the values of the angles are calculated as follows;
m∠A = x + 51
= -6 + 51
= 45⁰
m∠B = 81 + x
= 81 - 6
= 75⁰

What is the area of this compound shape?
Answer:
139.36
Step-by-step explanation:
first you do 8*8 because that would be the area of the square part
8*8=64
then find the area of the semicircle
first the Radis of it is 4 because 8/2=4
A=3.14R^2/2
3.14*4^2/2
3.14*16/2
50.24/2
25.12
now because there are 3 of the semicircles you do
25.12*3
75.36
then you add the 64 from the square to get your answer
75.36+64
139.36

Suppose that baby grand piano cost $8000 and looses 15%
in value each year. What would be the value of the piano in
12 years? Round your answer to the nearest hundred.
A.) $1137.93
B.) $1274.88
C.) $1078.44
D.) $5780.00
Answer:
A
Step-by-step explanation:
If it loses 15% of its value every year, then each subsequent year will be worth 85% of the previous year. If we think of this as a geometric series, then the worth would be 8000(.85^t) where t is years after the first year. If you plug in 12, then it's 1137.93.
Answer:
1137.93 is the answer

Chris and Eric are competing on a game show. Together they answer 22 questions correctly. Chris’ score was 8 less than twice Eric’s score. How many did each of the guys answer correctly?
Answer:
eric = 15
chris 7
Step-by-step explanation:
Let the questions Chris answered correctly be represented by c
Let the questions Eric answered correctly be represented by e
They both got 22 questions right. This can be represented by this equation :
c + e = 22 --- eqn 1
Chris scored 8 less than Eric. This can be represented by this equation :
c = e - 8 --- eqn 2
Substitute for c in eqn 1
e - 8 + e = 22 .
collect like terms
2e = 30
solve for e
e = 15
Substitute for e in eqn 2
c = 15 - 8 = 7

A fountain holds 12500 7/8 gallons of water. Joe wants to calculate how many liters that is. Which proportion could he use to solve for the number of liters? (1 gal = 3.79 L)
Answer:
47378.31625 Liters
Step-by-step explanation:
A fountain holds 12500 7/8 gallons of water. Joe wants to calculate how many liters that is. Which proportion could he use to solve for the number of liters? (1 gal = 3.79 L)
From the above question,
1 gallon = 3.79 Liters
12500 7/8 gallons = x Liters
Cross Multiply
x Liters = 12500 7/8 × 3.79 Liters
x = 47378.31625 Liters
Therefore, the number of liters of water in the fountain is 47378.31625 Liters

Find the value of x.
A 2
B 4.8
C 6
D 6.4
Answer:
D
Step-by-step explanation:
Δ DCA and Δ ABE are similar, thus the ratios of corresponding sides are equal, that is
[tex]\frac{CA}{BE}[/tex] = [tex]\frac{DA}{AE}[/tex] , substitute values
[tex]\frac{18}{10}[/tex] = [tex]\frac{x+8}{8}[/tex] ( cross- multiply )
10(x + 8) = 144 ( divide both sides by 10 )
x + 8 = 14.4 ( subtract 8 from both sides )
x = 6.4 → D
The value of x is the length of BD, so x = 6.So, The correct answer is C. 6.
The value of x is the length of the altitude from vertex B to side AC. We can find this length by using the Pythagorean Theorem on right triangle ABD.
[tex]AB^2 + BD^2 = AD^2\\8^2 + BD^2 = 10^2\\BD^2 = 36\\BD = 6[/tex]
The altitude from vertex B to side AC is equal to the length of BD, so x = 6.
Here is a breakdown of the steps involved in solving for x:
We are given the lengths of sides AB and AC of triangle ABC.
We know that the altitude from vertex B to side AC will be perpendicular to side AC. We can use the Pythagorean Theorem on right triangle ABD to find the length of BD, which is the altitude from vertex B to side AC.

is -6/3 and integer? dont guess ;( helppp
Answer:
no because
Fractions and decimals are not integers. All whole numbers are integers (and all natural numbers are integers), but not all integers are whole numbers or natural numbers. For example, -5 is an integer but not a whole number or a natural number.
-6/3 is not an integer.
What is Number system?A number system is defined as a system of writing to express numbers.
We need to check whether -6/3 is a integer or not .
An integer is a whole number (not a fractional number) that can be positive, negative, or zero.
The given number is a fraction which is not comes under the integers.
All whole numbers are integers but but not all integers are whole numbers or natural numbers.
If the fraction is simplified we get -2 which will be an integer but the fraction form is not considered as integer.

A container contains 3 yellow, 2 orange, and 4 pink roses. Without looking, if James chooses a rose from the container, what is the probability that James will select an orange rose?
Answer:
Orange rose = 2/9
Step-by-step explanation:
In order to find probability of picking one item, you add all the possible things you could choose. So, 3+2+4 equals a total of 9 outcomes, and that would be your denominator for your fraction of probability. From there it's really easy. Just put the amount of things your trying to find the probability for in the numerator spot.
Ex.
There are 9 total roses so that would be the denominator (?/9)
To find out the probability for picking an orange rose, you'd put the 2 in as the numerator because that is the total number of orange roses you have (2/?)
Then just put the two together (2/9).
