30 IS 15% of WHAT number?

A. 333.3
B. 266.6
C. 600
D. 200

Answers

Answer 1

Answer:

The correct answer is D) 200

Step by step explanation:

Let x be the number:

Then,

→15/100(x)=30

→3/20(x)=30

→3x/20=30

→3x=20⋅30

→3x=600

→x=600/3=200

Hope it helps!

Answer 2

Answer:

D 200

Step-by-step explanation:

Let the number we are find be x. We can write this as an equation:

30 = 15%*x = (15/100)x

Multiplying by 100/15 on both sides to isolate x:

x = 30(100/15) = 2(100) = 200

Therefore, 200 is our answer. I hope this helps! :)

This sin graph doesn't have a phase shift and its vertical displacement (d) is zero, so you don't need to include it in the equation of y = asin[b(x-c)]+d.

Solve in order of operation
Thanks

Answers

Answer:

b) 31 and c) 11

Step-by-step explanation:

IMPORTANT: Order of operations is PEMDAS (Parentheses, Exponents, Multiplication/Division, Addition/SUbtraction).

B) Solve inside the parentheses first.

1. 2^3 - 6 = (2*2*2) - 6 = 2.

2. Now the equation looks like 3 + 7 (2)^2, Next we need to do exponents.

3. 2 to the power of 2 is 4, leaving you with 3+7(4)

4. Now multiply 7*4, which is 28 then add 3 to it.

So B) would ultimately be 31.

C) As we did in equation B, we start with parentheses.

1. (6/3) we can just simplify this to 2, so those parentheses are out of the way.

2. Now we need to do exponents, (-3)^2. This is the same as -3 * -3. This would equal 9.

3. So far the equation looks like 4 + 9 - 2 / 2.

4. Next would be to solve any multiplication/division problems we have. We can see from step 3 that we have a -2 divided by a positive 2. This would give us -1.

5. Now the equation looks like 4 + 9 - 2. Now you can just working from left to right.

So C) would solve to 11

Clare is 5 years older than her cousin. cousin How old would Clare be if her cousin is: A. 10 years old? B. 2 years old? C. X years old? Clare is 12 years old. How old is Clare's cousin?

Answers

Answer:

if her cousin is 10 clare will be 15, cousin=2 clare=7, cousin=x clare= x+5. if clare= 12 then 12-5=7

The age of cousin when Clare is 12 years old is computed as 7 years.

What is meant by mathematical operations ?

Mathematical operations are defined as the operations used for calculating or computing various solutions of two or more values.

Here,

Given that, Clare is 5 years older than her cousin.

Age of Clare at different ages of her cousin is calculated.

A) 10 years old

Age of Clare = 10 + 5 = 15 years old

B) 2 years old

Age of Clare = 2 + 5 = 7 years old

C) X years old

Age of Clare = X + 5 years old

Cousin's age when Clare is 12 years old can be calculated as,

Age of cousin = 12 - 5 = 7 years old

Hence,

The age of cousin when Clare is 12 years old is computed as 7 years.

Solve the equation below for x.
cx- 4 = 7

A. x=11/c
B. x=c/3
C. x=3/c
D. x= c/11

Answers

Answer:

a. x = 11/c

Step-by-step explanation:

cx - 4 = 7 [add 4 to both sides of the equation]

cx = 11 [divide by c to isolate x]

x = 11/c

Calculate the distance between the points N=(-9,9) and H=(-3,2) in the coordinate plane.

Answers

Answer:

[tex]\sqrt{85}[/tex] units

Step-by-step explanation:

Calculate the distance d using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = N(- 9, 9) and (x₂, y₂ ) = H(- 3, 2)

d = [tex]\sqrt{-3+9)^2+(2-9)^2}[/tex]

= [tex]\sqrt{6^2+(-7)^2}[/tex]

= [tex]\sqrt{36+49}[/tex]

= [tex]\sqrt{85}[/tex]

If one diagonal is 12 inches long and the other is 32 inches long, how many inches long, to the nearest hundredth of an inch, is a side of the rhombus

Answers

Answer:

17.09 inch

Step-by-step explanation:

Given that:

A rhombus with diagonals of length 12 inches and 32 inches.

To find:

The length of rhombus to the nearest hundredth of an inch.

Solution:

First of all, we need to learn about the property of a rhombus, its sides and its diagonals.

The diagonals of a rhombus intersect each other by bisecting each other and are perpendicular to each other.

And all the sides

Kindly refer to the attached image for the given dimensions.

Now, there are four right angled triangles in which we can use Pythagorean theorem to find hypotenuse which is nothing but the side of rhombus.

According to Pythagorean theorem:

[tex]\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Perpendicular}^{2}\\\Rightarrow Side^{2} = 6^{2} + 16^{2}\\\Rightarrow Side^{2} = 292\\\Rightarrow Side \approx \bold{17.09\ inch}[/tex]
