5. From 13 friends to 14 friends

Answer:

$1,100

Step-by-step explanation:

Since we that 75% less than the original price, or 15% of the original price*, is equal to $165, we can set up an equation like this, where [tex]x[/tex] represents the original price:

[tex].15x=165[/tex]

Now, just solve for [tex]x[/tex] by dividing both sides by .15, the equivalent of 15%:

[tex]x=\frac{165}{.15}\\x=1100[/tex]

Therefore, the original price of the suit was $1,100.

*The reason that we use .15 instead of .75 is that when something is on sale with 75% of the original price cut off, 15% of the original price remains. That's why [tex].15x=165[/tex].

Answer:

90.27mm

Step-by-step explanation:

radius=16mm

diameter=16mm x 2

=32mm

total length=1/2 x pi x 32mm +20mm+20mm

= 90.27mm (nearest hundredth)

Answer:

90.27 mm (nearest hundredth)

Step-by-step explanation:

Circumference of a circle = [tex]2\pi r[/tex] (where r is the radius)

Therefore, the arc length = 1/2 x 2 x [tex]\pi[/tex] x 16 = 16[tex]\pi[/tex]

So total perimeter = 2 x 20 + 16[tex]\pi[/tex] = 90.27 mm (nearest hundredth)

Answer:

20

Step-by-step explanation:

Based on the given conditions, formulate 7 divided by 0.35

Multiply both the numerator and denominator with the same integer: 700/35

Cross out the common factor:20

Find the largest integer less than or equal to 20:20

Answer: 20

Answer:

x = 55

Step-by-step explanation:

A triangle has angles that add up to 180, so lets make an equation

25 + 100 + x = 180

125 + x         = 180

-125                -125

         x         = 55

Answer:

[tex]\huge\boxed{x<2}[/tex]

Step-by-step explanation:

This inequality can be solved similarly to any equation.  Simply add 1 to both sides of the equation:

8x - 1 + 1 < 15 + 1

8x < 16

Then divide both sides by 2:

8x / 8 < 16 / 8

x < 2

Answer:

-8

2

12

52

Step-by-step explanation:

y = 10x + 2

x = -1, y = 10(-1) + 2 = -8

x - 0, y = 0 + 2 = 2

x = 1, y = 10 + 2 = 12

x = 5, y = 10*5 + 2 = 52

Answer: 32 sweets

[] The ratio 5:2 goes in the word "toys and sweets" as it is said in the sentence.

-> 5 toys for every 2 sweets

[] We know we will have 16 bags in total. She has exactly enough toys

-> 16 bags in total * 5 toys per bag = 80 toys

[] Because of this, we can multiply 2 by 16 to see how many sweets will be needed.

-> 16 bags in total * 2 sweets per bag = 32 sweets

Answer : 9/8 Or 1 1/8

◊ YusuCr ◊

Hello!

Here we have fractions with unlike denominators.

So, we need to find the common denominator (the LCM of both denominators).

LCM stands for Least Common Multiple.

So, what is the L.C.M. of 4 and 8?

It is 8.

So, 8 is the lowest common denominator.

Now, we multiplied the denominator of the first fraction by 2, so we multiply the numerator by 2:

[tex]\bf{\displaystyle\frac{3}{4} = \frac{6}{8}[/tex]

Now, add:

[tex]\bf{\displaystyle\frac{6}{8} +\frac{3}{8}[/tex]

[tex]\bf{\displaystyle\frac{9}{8}[/tex]

Final Answer:

[tex]\bf{\displaystyle\frac{9}{8}[/tex] (Improper fraction)

[tex]\bf{\displaystyle1\frac{1}{8}[/tex] (Mixed number)

I hope it helps you.

Good luck and enjoy your day!

Answer:  

Use the given functions to set up and simplify 12 % . 8500 = 12 % = 0.12 84 a mo = 0.12 18 mo = 0.12

Step-by-step explanation:

Answer:

2

Step-by-step explanation:

Let us find 1/4 of 8.

We can write 1/4 of 8 as 1/4 × 8

To multiply fractions through the following steps:

Multiply the numerators.

Multiply the denominators.

Reduce the resultant fraction to its lowest terms.

Now,

1/4 × 8 = (1 × 8) / 4 = 8/4 = 2

Thus, our answer is 2

Number of slices Dominick ate = 2

Fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing. All fractions consist of a numerator and a denominator and they are separated by a horizontal bar known as the fractional bar.

Given,

Dominick ate 1/4 of an 8 slice of pizza

No. of slices Dominick ate

= 1/4 × 8

= 2

Hence, 2 slices of pizza were eaten by Dominick.

Answer:

x=-1,2,3

Step-by-step explanation:

f(x) = 0 means we want to find where the graph has a y value of 0

In this example, the graph has a y value of 0 when x =-1 and when x = 2 and when x=3

There are 3 solutions to the equation f(x) = 0

Answer:

Apply the product rule to −10x.

Raise −10 to the power of 2.

100x²

In this exercise we have to use the derivative knowledge to calculate the value, we have that:

[tex]10x^2/2+2x[/tex]

A derivative of a sum of two functions f(x) and g(x) is a sum of the derivatives of f(x) and g(x). For example, let h(x) = 3x + 5x². A derivative of h(x) is h'(x) = 3 + 10x.

Given that

[tex](10x+2)[/tex]^

We have:

[tex]\int\limits {10x+2} \, dx = 10x^2/2+2x[/tex]
