Marissa jumped 42 times in 7 hours. At that rate, how many times would she jump in 30 minutes?

Answers

Answer 1

Answer:

3

Step-by-step explanation:

Well first let's calculate how many times she jumped per hour. For that we need to divide 42 by 7 which is 6. Now we need to divide that by two because they are asking for every half hour, not every hour. So 6 divided by 2 is 3. So our answer is 3.

what is the value of y?
A. 40°
B. 30°
C. 120°
D. 60°

Answers

Answer

60

Step-by-step explanation:

A triangle is 180 degrees. So first since you have one of the degrees you will do 180-60=120. Since the 2 ys are the same you can just divide 120 by 2. Which is 60. So y=60

Answer:

D - 60° because all the angles in a triangle add up to 180°

Step-by-step explanation:

help plz help plz help plz help plz​

Answers

Answer:

Step-by-step explanation:

21. 136° and b are supplementary, meaning they have a sum of 180°. This means that 136° + b = 180° → b = 44°.

22. Again, the angles are supplementary which means that 61° + b = 180° → b =   119°.

23. Again, they are supplementary which means that x - 22° + 135° = 180° → x + 113° = 180° → x = 67°.

24. I'm pretty sure you get the gist of this. 6x + 3° + 87° = 180° → 6x + 90° = 180° → 6x = 90° → x = 15°

Answers

Options

[tex]A)\sqrt[6]{k^{-1}}\\(B)\dfrac{1}{k^6}\\(C)\left(k^{-1}\right)^{^{\scriptsize\dfrac{1}{6}}}\\[/tex]

Answer:

[tex](A)\sqrt[6]{k^{-1}}\\(C)\left(k^{-1}\right)^{{1/6}}[/tex]

Step-by-step explanation:

Given the expression [tex]k^{^{-\dfrac{1}{6}}}[/tex] , we apply the following rule of indices to obtain equivalent forms.

Negative Exponent Rule: [tex]a^{-m}=\dfrac{1}{a^m}[/tex]Fractional Exponent Rule:  [tex]a^{1/m}=\sqrt[m]{a}[/tex]

Therefore:

[tex]k^{-1/6}=(k^{-1})^{1/6}[/tex]

This is Option C,

If we simplify further, we obtain:

[tex]k^{-1/6}=(k^{-1})^{1/6}\\=\sqrt[6]{k^{-1}}[/tex]

This is option A.

Therefore, Options A and C are equivalent to the given expression.

B. Perimeter of the base
C. Length of the base
O D. Volume of the base

Answers

Answer:

A.Area of the base

Step-by-step explanation:

these is obtained by multiplying the length and width of the base to get the area of the base

The variable B in the Formula is area of Base.

What is Volume?

Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.

Pyramid volumes are measured by how much space they take up or by how many unit cubes can fit inside of them. A pyramid is a polyhedron because it has polygonal faces.

As, Volume of pyramid = (1/3) (Bh), where

B = Area of the base of the pyramid

h = Height of the pyramid.

So, B in the Formula is area of Base.

If Sue worked 7 1/4 hours on Monday, 3 hours on Tuesday, 6 3/4 hours on Wednesday, 8 hours on Thursday, and 5 hours on Friday, calculate her weekly wage at $4.10 per hour

Answers

Answer:

$123

Step-by-step explanation:

Let's find the total amount of hours Sue worked. To do so, we'll do 7.25 + 3 + 6.75 + 8 + 5 = 30 total hours. Now, we'll multiply 4.1 by 30 because she receives $4.10 for every hour. 4.1 * 30 = $123. Hope this helps!
