Answer:
4
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
Write 5% as
5/100
Since, finding the fraction of a number is same as multiplying the fraction with the number, we have

Step-by-step explanation:
Answer:
Original options: -2 2/3 --> -2.43 --> 2.045 --> 2 5/9
Step-by-step explanation:
It will help to make all of the numbers the same, into all fractions or all decimals, so you can compare them easier. I will make them decimals.
-2 2/3 --> -2.6666... (the 6s don't end)
-2.43
2 5/9 --> 2.5555... (the 5s don't end)
2.045
You can easily split the options in half, as the top two are both negative and the bottom two are positive. So you have to figure it out amongst the two groups.
From least to greatest: -2.666 --> -2.43 --> 2.045 --> 2.555
Original options: -2 2/3 --> -2.43 --> 2.045 --> 2 5/9

Which property will we need to use to solve the equation?
x - 10 = 5
Answer:
Addition Property of Equality
Step-by-step explanation:
To solve this equation, we need to use the Addition Property of Equality because we need to add 10 to both sides to isolate x...
x-10=5
x-10+10=5+10
x=15
In a right triangle, sin (3x+5)^\circ(3x+5) = cos (8x+9)^\circ(8x+9) Solve for x. Round your answer to the nearest hundredth if necessary.
Right triangles are triangles with a measure of 90 degrees
The value of x is 76/11
How to calculate x in the triangleThe equation is given as:
sin (3x+5) = cos (8x+9)
To solve for x, we make use of the following theorem
If sin(A) = cos(B), then
A + b = 90
So, we have:
3x + 5 + 8x + 9 = 90
Collect like terms
3x + 8x = 90 - 5 - 9
Evaluate the like terms
11x = 76
Divide both sides by 11
x = 76/11
Hence, the value of x is 76/11

Please help me!!!!!!!!
Step-by-step explanation:
Let's turn each mixed fraction into an improper fraction.
[tex]1 \frac{1}{4} = \frac{4}{4} + \frac{1}{4} = \frac{5}{4} [/tex]
[tex]2 \frac{1}{5} = \frac{5}{5} + \frac{5}{5} + \frac{1}{5} = \frac{11}{5} [/tex]
We'll use 11/5 twice.
Multiply:
[tex] \frac{5}{4} \times \frac{11}{5} = \frac{55}{20} [/tex]
[tex] \frac{55}{20} = \frac{20}{20} + \frac{20}{20} + \frac{15}{20} = 2 \frac{15 \div 5}{20 \div 5} = 2 \frac{3}{4} [/tex]
Multiply the Second problem:
[tex]\frac{5}{6}\times\frac{11}{5}=\frac{55}{30}[/tex]
[tex]\frac{55}{30} =\frac{30}{30} +\frac{25}{30}= 1 \frac{25 \div 5}{30 \div 5} = 1 \frac{5}{6}[/tex]

100 Points!!!
The table shows the number of calories in different numbers of apples.
Number of apples 3 5 8
Number of calories 195 325 520
How many calories are in 9 apples?
Answer:
585 calories are in 9 apples
Step-by-step explanation:
Number of apples : 3 || 5 || 8
Number of calories: 195 || 325 || 520
Find the unit rate:
[tex]\frac{y2-y1}{x2-x1}[/tex]
[tex]\frac{325-195}{5-3}[/tex]
[tex]\frac{130}{2}[/tex]
[tex]65[/tex]
Find equation:
y - 325 = 65( x -5)
y = 65x - 325 +325
y = 65x .....this is the equation to find any number of calories.
put x as 9 here:
y = 65x
y = 65(9)
y = 585 calories
