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

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]

Answers

Answer:

Use the slope-intercept form to find the slope. The slope-intercept form is y=mx+b y = m x + b , where m m is the slope and b b is the y-intercept. Using the slope-intercept form, the slope is 3 3 . All lines that are parallel to y=3x+4 y = 3 x + 4 have the same slope of 3 .

6/a - 4/b = 1 and 9/a - 8/b = 1

Answers

Answer:

a = 3 ; b = 4

Step-by-step explanation:

Eqn.1 = [tex] \frac{6}{a} - \frac{4}{b} = 1[/tex]

Eqn.2 = [tex] \frac{9}{a} - \frac{8}{b} = 1[/tex]

Both the eqns have RHS (Right Hand Side) equal. So,

[tex] \frac{6}{a} - \frac{4}{b} = \frac{9}{a} - \frac{8}{b} [/tex]

[tex] = > \frac{6b - 4a}{ab} = \frac{9b - 8a}{ab} [/tex]

Cancelling ab from both the denominators of both the sides,

[tex] = > 6b - 4a = 9b - 8a[/tex]

[tex] = > 8a - 4a = 9b - 6b[/tex]

[tex] = > 4a = 3b[/tex]

[tex] = > a = \frac{3b}{4} [/tex]

Putting the value of a in Eqn.1,

[tex] \frac{6}{ \frac{3b}{4} } - \frac{4}{b} = 1[/tex]

[tex] = > \frac{24}{3b} - \frac{4}{b} = 1[/tex]

[tex] = > \frac{8}{b} - \frac{4}{b} = 1[/tex]

[tex] = > \frac{8 - 4}{b} = 1[/tex]

[tex] = > b = 4[/tex]

Putting the value of b in the value of a

[tex]a = \frac{3 \times 4}{4} = 3[/tex]

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.

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)

Tammy figured her math exam would be difficult unless she put in at
least 15 hours of study time to prepare. She studied 2½ hours on
Monday, 3 hours on Tuesday, 4¾ hours on Wednesday, and 4 ½
hours on Thursday. Did she study for at least 15 hours? Explain.

Answers

Answer: No, she did not study for at least 15 hours.

=======================================================

Explanation:

Fractions are often a pain, so I find it easier to convert to decimal form whenever possible.

1/2 = 0.5

3/4 = 0.75

which lead to,

2 & 1/2 = 2 + 1/2 = 2 + 0.5 = 2.5

4 & 3/4 = 4 + 3/4 = 4 + 0.75 = 4.75

4 & 1/2 = 4 + 1/2 = 4 + 0.5 = 4.5

-----------------------------

We can then rephrase the problem like so:

"She studied 2.5 hours on Monday, 3 hours on Tuesday, 4.75 hours on Wednesday, and 4.5 hours on Thursday"

Add up those decimal values to get:

2.5 + 3 + 4.75 + 4.5 = 14.75

In total, Tammy studied for 14.75 hours, which is equivalent to 14 & 3/4 hours.

This result is smaller than 15, so she did not study for at least 15 hours.

Note: "at least 15" is the same as saying "15 or more".

Eric's father Works two part-time jobs one in the morning and one in the afternoon and works a total of 40 hours each five day workweek if your schedule is the same each day and he works 3 hours each morning how many hours does Eric's father work each afternoon

Answers

Answer:

Step-by-step explanation:

because 40 devided by 5 equals 8 so thats how many hours in the afternoon

3 * 5 = 15 that is how many hours he works in the mornings

40 - 15 = 25

He works 25 hours in the afternoon every week.
25 / 5 = 5

So his father works 5 hours every after noon 5 days out of the week

A chemist is using 353 milliliters of a solution of acid and water. If 14.7 of the solution is acid, how many milliliters of acid are there? Round your answer to the nearest tenth

Answers

Answer:

The amount of Acid in a solution = 51.9 millimeters

Step-by-step explanation:

Given that the total amount of solution of acid and water = 353 milliliters

Acid percentage = 14.7%

Thus, in order to determine the amount of acid, all we need is to multiply 353 with 14.7% or 0.147.

i.e

Amount of Acid = 14.7% of 353

= 0.147 × 353

= 51.9 millimeters

Therefore, the amount of Acid in a solution = 51.9 millimeters

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
