Answer:

[tex]\dfrac{-79}{126}[/tex]

Step-by-step explanation:

The given expression is :

[tex]\dfrac{-2}{3}+\dfrac{5}{7}+\dfrac{-8}{9}+\dfrac{3}{14}[/tex]

The LCM of 3,7,9 and 14 is 126

So,

[tex]\dfrac{-2}{3}+\dfrac{5}{7}+\dfrac{-8}{9}+\dfrac{3}{14}=\dfrac{42(-2)+18(5)+14(-8)+9(3)}{126}\\\\=\dfrac{-79}{126}[/tex]

So, the value of the given expression is equal to [tex]\dfrac{-79}{126}[/tex].

Answer:

D  36πa^6b^9

Step-by-step explanation:

Step 1. Write the formula for the volume of a sphere.

V = (4/3)πr³

Step 2. Replace r with the given radius. Since the given radius is an expression, remember to enclose it in parentheses and cube the entire expression.

V = (4/3)π(3a²b³)³

Step 3. Simplify the expression. Start by cubing each factor inside the parentheses.

V = (4/3)π ×(3)³(a²)³(b³)³

To raise an exponent to an exponent, multiply the exponents.

V = (4/3)π × 27a^6b^9

V = (4/3 × 27)πa^6b^9

V = 36πa^6b^9

Answer:

Step-by-step explanation:

Answer:

1. True

2. HGK

3. 17⁰

Step-by-step explanation:

1. All angles in a triangle need to add up to 180. The right angle is a given 90⁰ so the other two angles need to add up to 90⁰ to equal 180⁰. Angle C corresponds to Angle K so Angle H corresponds to Angle E. So add Angle C and H together and it sums up to 90⁰ so it is true.

2. HGK; you match it up with the markings inside the triangle

3. Same logic with number 1 but you subtract 90 from 73 to find Angle K.

Remark

The key to this question is to get the original price (36) down to 29.52. In other words, what % will when multiplied by 36 will result in 29.52?

Solution

36 * (x/100) = 29.52   Multiply both sides by 100

36 * x = 29.52 * 100  The 100 on the left disappears.

36 * x = 2952              The decimal disappears. Divide by 36

x = 2952/36

x = 82%

That is not your answer. That just tells you what % of 36 is that would give 29.52

Answer

The % discount is 100 - 82 = 18%. That is the % discount.

Answer: 693 students are female

Step-by-step explanation: Calculating fourty-nine point five of one thousand, four hundred. How to calculate 49.5% of 1400? Simply divide the percent by 100 and multiply by the number. For example, 49.5 /100 x 1400 = 693 or 0.495 x 1400 = 693.

Answer:

707 females

Step-by-step explanation:

1400 x 0.495 = 693

Then,

1400 - 693 = 707

707 are girls.

Step-by-step explanation:

The function crosses the y-axis at (0, -3)

A nearby maximum can be found at (1.57, -2) or (π/2, -2)

A nearby maximum can be found at (3.14, -2) or (π, -2)

Answer:

5^2 = 3^2 + x^2 = 4

Step-by-step explanation:

Answer:

1/32

Step-by-step explanation:

So we know that green shirts can be represented by 1/4 of 1/8. It's 1/4 of the 1/8 of shirts in the store. The key word here is "of," which means multiplication.

So you can replace 1/4 of 1/8 with:

[tex]\frac{1}{4} x \frac{1}{8}[/tex]

To multiply fractions, it's really simple: multiply the denominator with the denominator and the numerator with the numerator.

[tex]\frac{1}{4} x \frac{1}{8} = \frac{1}{32}[/tex]

So 1/32 of the entire store is green shirts.

Answer:

520 cubic centimeters (cm^3)

Step-by-step explanation:

volume = length * width * height

length = 13

width = 5

height = 4 + 4, so height = 8

volume = (13) * (5) * (8)

volume = 520 units

Since the given measurements are in centimeters and the answer is the volume of the prism, the answer must be in cubic centimeters

So, the final answer is 520 cubic centimeters (cm^3)

Answer:

528 miles

Step-by-step explanation:

The unit of miles per gallon is 33

Use the 396/12 to find that

To find how much for 16 gallons multiply 16 by 33

16*33 = 528

On 16 gallons she can drive 528 miles

Violet drove a distance of 396 miles on 12 gallons of gas. which is determined by the given proportion.

A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other.

Given that she drove 396 miles on 12 gallons of gas.

Let the number of miles would be x can she drive on 16 gallons of gas.

According to the given question, we can write a proportion as

396 miles : 12 gallons = x miles : 16 gallons

396 / 12 = x / 16

Apply the cross-multiplication operation,

396 × 16 = 12x

12x = 6,336

x = 6,336 / 12

Apply the division operation,

x = 528

Therefore, she drove a distance of 396 miles on 12 gallons of gas.

Answer:

Option A is correct:

x + 4 < 12

Step-by-step explanation:

The sum of x and 4 means addition:

x + 4

less than 12 means <:

x + 4 <12

Have a nice day!

Answer: A.) x + 4 < 12

Step-by-step explanation: With the process of elimination, there would only be two possible answers: (A. x + 4 < 12 and C. 4x < 12) because in the problem, it says less than. Since, x and 4 cannot mean 4x since that means multiplication, the only available answer would be A. x + 4 < 12).
