(2 to the power -1 ÷ 5 to the power- 1)2 × -5/8 to the power -1
Answers
Answer:
-8
Step-by-step explanation
2 to the power of -1 = 0.5
5 to the power of -1 = 0.2
0.5/0.2 = 2.5
So,
(2.5)2 x -5/8 to the power of -1
-5/8 = -0.625
-0.625 to the power of -1 = -1.6
So,
(2.5)2 x -0.625
5 x -0.625
= -8
Answer:
-8
Step-by-step explanation:
(2^-1 ÷ 5^-1) = 5/2
(5/2) x 2 = 10/2 or 5
-5/8 ^-1 = - 8/5
5 x - 8/5 = -40/5 or -8

A large pizza at a restaurant has the dimensions shown. Find the area of the pizza. Use4 for T. 14 in. 22 Why does it make sense to use as the estimate for T? Explain your reasoning. PLEASE HELP
Answers
You need to figure out the total area of the pizza (a circle) and then divide it by the area of each slice to get the number of slices of pizza. By the way, area should be in square units, so I assume you mean 14.125 in2.
So, Area of a circle = πr2
Diameter = 2 x the radius (r). So, if the diameter = 14 in, 14 in = 2 r, and dividing both side by 2, r = 7 in.
Area of a circle = Π (7 in)2 = 153.938 in2
Now, divide this total area of the pizza, 153.938 in2, by the area of one slice, 14.125 in2.
153.938 in2/14.125 in2 = 10.898 slices or about 11 slices of pizza
Becca made 960 cookies to sell. She wants to package the cookies in the the boxes of 16 . Her goal is to make $630 from selling her cookies . If each box of cookies is priced the same , how much should Becca charge for each box ?
Answers
Step-by-step explanation:
Total cookies = 960
Each box has 16 cookies
Her goal is $630
First, you want to find out how many boxes she made
960÷ 16 = 60
She made 60 boxes
Now you want to find the price for each box
630 ÷ 60 = 10.5
She should charge $10.50 for each box

Choice c. [tex]\sqrt{12}[/tex]
Step-by-step explanation:
Vectors
Suppose we have a vector v defined as
[tex]\vec v=a\mathvf{i}+b\mathvf{j}[/tex]
The magnitude of the vector is:
[tex]\mid\mid\vec v\mid\mid=\sqrt{a^2+b^2}[/tex]
On the other hand, the dot product of the vector by itself is:
[tex]\vec v\cdot\vec v=a*a+b*b=a^2+b^2[/tex]
Note the relation between these two operations is:
[tex]\mid\mid\vec v\mid\mid=\sqrt{\vec v\cdot\vec v}[/tex]
Since we are given:

you roll a single die numbered from 1 to 6 twice. what is the probability of rolling a 6 the first time and an odd number second
Answers
Answer:
1/12
Step-by-step explanation:
Since the two rolls are independent, then the chance of getting a 6 in the first and an odd number in the second is obtained by multiplying the two probabilities.
1/6 is the probability of rolling 6, 1/2 is the probability of rolling an odd number
1/6 times 1/2 is 1/12

Answers
Answer:
-7
Step-by-step explanation:
well, y-intercept is value of y when x = 0.
from the problem, we already have the answer, it is -7
but more detailed way is
m = -3
[tex] \frac{y - ( - 7)}{x - 0} = - 3 \\ y - ( - 7) = - 3x \\ y = - 3x - 7 \\ [/tex]
y-intercept is value of y when x = 0
[tex]y = - 3(0) - 7 \\ y = - 7[/tex]
