Answer:

[tex]-\frac{2197}{3375}\\\mathrm{Decimal:\quad }\:-0.65096[/tex]

Step-by-step explanation:

[tex]-\left(\frac{13}{15}\right)^3\\\mathrm{Apply\:exponent\:rule}:\quad \left(\frac{a}{b}\right)^c=\frac{a^c}{b^c}\\\left(\frac{13}{15}\right)^3=\frac{13^3}{15^3}\\=-\frac{13^3}{15^3}\\13^3=2197\\=-\frac{2197}{15^3}\\15^3=3375\\=-\frac{2197}{3375}[/tex]

Answer:

[tex] = \frac{ - 2197}{3375} [/tex]

Step-by-step explanation:

[tex]cube = {x}^{3} \\ (\frac{ - 13}{15}) ^{3} \\ \frac{ - 13}{15} \times \frac{ - 13}{15} \times \frac{ - 13}{15} \\ \\ = \frac{ - 2197}{3375} [/tex]

Answer:

4/8 +6/8 I just verfying the other person's. ok

Step-by-step explanation:

I did it on a calculator ;b

PLEASE MARK FallOutChild brainliest!!

Answer:

4/8 + 6/8 = 10/8 or 1 2/8, 1 1/4

Step-by-step explanation:

When it asks for like units, it's asking for the same denominator value. You can not add fractions together when they do not have a common denominator

if you multiply the denominator and numerator in 2/4 by 2, you get 4/8

Result of 4/8 + 6/8 gives you an improper fraction of 10/8

Answer:2.5 cups

Step-by-step explanation:

Given

Rosanne runs 6 miles in an hour

If she drinks 0.5 cups of water every  [tex]\frac{1}{3}[/tex]  of an hour

So in 1 hour Rosanne drinks 1.5 cups

So, for 6 miles Rosanne drinks 1.5 cups

i.e. For   [tex]1\ mile \quad \equiv \quad \frac{1}{4}\ \text{cup}[/tex]

for    [tex]10\ mile\quad \equiv \quad \frac{10}{4}\ \text{cup}[/tex]

[tex]=2.5\ \text{cup}[/tex]

Answer:

M = [tex]\frac{2}{3}[/tex]

Step-by-step explanation:

The two coordinate points given are (2,2) and (-1,0).

We can use the slope formula to find the slope.

[tex]Slope(m)=\frac{y2-y1}{x2-x1}[/tex]

[tex]m=\frac{0-2}{-1-2}[/tex]

[tex]m=\frac{-2}{-3} or \frac{2}3}[/tex]

Answer:

is the longest side in a triangle

Step-by-step explanation:

is the longest side in a triangle

Answer:

It is the longest side of a right triangle.

Step-by-step explanation:

A right triangle has two legs, then the (i call it a slope) hypotenuse connects the two from the top of one of leg to the end of the bottom leg.

you can calculate the hypotenuse via the Pythagorean theorem. which is A^2+B^2=C^2

Or: Leg 1^2+ Leg 2^2= Hypotenuse^2

Answer:

Applying Pythagorean theorem:

r = sqrt(3^2 + (14/2)^2) = sqrt(9 + 49) = sqrt(58) = ~7.6 cm

x intercepts are x=2 and x=6

greatest value of y is y=2 and it occurs when x=4

for x between... what are the options?

   if the options are greater than, equal to, or less than, the answer is greater than

Answer:

-15

Step-by-step explanation:

Answer:

$754.05

Step-by-step explanation:

We have to find the volume of one tank and multiply it by the cost of renting the tank per cubic foot.

The volume of a cylinder is:

[tex]V = \pi r^2h[/tex]

where r = radius

h = height

Each tank has a diameter of 8 feet (radius = 4 feet) and a height of 3 feet.

The volume of the tank is therefore:

[tex]V = \pi * 4^2 * 3 = 150.81 ft^3[/tex]

The cost of renting is $5 per cubic foot.

Therefore, the cost of renting a tank is:

150.81 * 5 = $754.05

It costs $754.05 to rent a tank.

Answer:

Given:

Sample size, n = 6965

Sample proportion p' = [tex] \frac{1330}{6965} = 0.19 [/tex]

Let's claim that the return rate is less than​ 20%, ie, P = 0.2

Significance level = 0.01

The null and alternative hypotheses:

H0 : P = 0.2

H1 : P < 0.2

Option A is correct

_____________________________

For the test statistic, Z, let's use the formula:

[tex] Z = \frac{p'- P}{\sqrt{\frac{P(1-P)}{n}}} [/tex]

[tex] = \frac{0.19 - 0.2}{\sqrt{\frac{0.2(1 - 0.2)}{6965}}} = -1.887 [/tex]

Z = -1.887 ≈ -1.89

___________________________

The p-value.

This is a left tailed test.

Using z table,

P-value = P(Z ≤ -1.89) = 0.029

The pvalue is 0.029

Decision:

Because the pvalue, 0.029 is greater than level of significance, 0.01, we fail to reject null hypothesis, H0.

Conclusion:

There is not enough sufficient evidence to conclude that the return rate is less than 20%

Answer:

7t +5

Step-by-step explanation:

6t +7 -2 +t

Combine like terms

6t+t  +7-2

7t +5

Answer:

Relax. The answer is 7t +5

Step-by-step explanation:

Circle the 2 variables (T)

Next re-write the equation and put the varbiles equation 6t+t.

Then you have 7-2 left, you then put it next to the new equation but make sure when you do that it looks like this 6t+t+7-2.

Last you solve and your answer should be 7t+5.

Note: If a variable is alone like the t then make sure you put a one next to it

Answer:

-The volume of the cone is 100.5[tex]in^3[/tex] .

Step-by-step explanation:

To find the volume of cone, you need the formula:

[tex]V =\frac{1}{3} \pi r^2 h[/tex]

-Use the radius and the height for the formula:

[tex]V =\frac{1}{3} \pi 4^2 6[/tex]

-Then, you solve:

[tex]V =\frac{1}{3} \pi 4^2 6[/tex]

[tex]V = \frac{1}{3}\pi[/tex] × [tex]4^2[/tex] × [tex]6[/tex]

[tex]V = \frac{1}{3}\pi[/tex] × [tex]16[/tex] × [tex]6[/tex]

[tex]V = \frac{1}{3}\pi[/tex] × [tex]96[/tex]

[tex]V = \frac{96}{3} \pi[/tex]

[tex]V = 32\pi \approx 100.53[/tex]

-Round to the nearest tenth:

[tex]V \approx 100.5[/tex]

So, therefore, the volume of the cone is 100.5[tex]in^3[/tex] .

Answer:

Step-by-step explanation:

TRUE angles are linear pairs

Answer:

No

Step-by-step explanation:

Not all parallelograms are rhombuses, some parallelograms include rectangles, squares, hexagons, etc.

No. Jan is not correct. So, all parallelograms are not rhombuses.

A rhombus is a parallelogram because the opposite sides are parallel but every parallelogram is not a rhombus because all sides may not be equal. Every square is a rectangle because opposite sides are equal but not every rectangle is a square because all sides might not be equal. Every square is rhombus because all sides are equal but not every rhombus is a square because the angles might not be right angles.

here, we have,

We need to identify the properties of the given figure in order to answer why one figure can not be the other one:

A rhombus has all sides equal as well as parallel but all angles might not be right angles.

A square has all four sides equal and has 4 right angles.

A rectangle has equal opposite sides and 4 right angles.

A parallelogram has opposite parallel sides.

Hence, a rhombus can be a parallelogram because the opposite sides are parallel but every parallelogram can not be a rhombus because all sides may not be equal. Every square is a rectangle because opposite sides are equal but not every rectangle is a square because all sides might not be equal. Every square is rhombus because all sides are equal but not every rhombus is a square because the angles might not be right angles.

A parallelogram has opposite sides parallel and equal in length. Also, opposite angles are equal. Squares, rectangles, and rhombuses are all parallelograms. So all parallelograms are not rhombuses.

Not all parallelograms are rhombuses, some parallelograms include rectangles, squares, hexagons, etc.

Good luck on your assignment

We have been given that side length of pyramid the square base is 12 cm and its slant height is 10 cm. We are asked to find the height of the pyramid.

We will use slant height of a pyramid formula to solve our given problem.

[tex]s=\sqrt{h^2+\frac{1}{4}a^2}[/tex],where,

s = Slant height,

h = Height,

a = Each side of square base.

Upon substituting our given values in above formula, we will get:

[tex]10=\sqrt{h^2+\frac{1}{4}\cdot 12^2}[/tex]

[tex]10=\sqrt{h^2+\frac{1}{4}\cdot 144}[/tex]

[tex]10=\sqrt{h^2+36}[/tex]

Switch sides:

[tex]\sqrt{h^2+36}=10[/tex]

Let us square both sides:

[tex](\sqrt{h^2+36})^2=10^2[/tex]

[tex]h^2+36=100[/tex]

[tex]h^2+36-36=100-36[/tex]

[tex]h^2=64[/tex]

Now we will take positive square root of both sides.

[tex]\sqrt{h^2}=\sqrt{64}[/tex]

[tex]h=8[/tex]

Therefore, the height of the pyramid is 8 cm and option 'b' is the correct choice.
