Lets use the other 5 since it is already given to us.
so 8x5=40
no we must get 200 with the 40
so 200/40=5

Step-by-step explanation:
Diego is buying shrimp and rice to make dinner. Shrimp
costs $6.20 per pound and rice costs $1.25 per pound.
Diego spent $10.55 buying shrimp and rice.
The relationship between pounds of shrimp s, pounds
of rice r, and the total cost is represented by the
equation 6.20s + 1.25r= 10.55.
Write an equation that makes it easy to find the number
of pounds of rice if we know the number of pounds of
shrimp purchased.
Answer:
r= (10.55−6.20s)
--------------------------
1.25
Step-by-step explanation:
Using the principle of subject of formula, we make number of pounds of rice, r the subject of the given equation. Hence, the equation would be r = (10.55 - 6.20s)/1.25
Given the expression :
6.20s + 1.25r = 10.55
Isolate 1.25r
1.25r = 10.55 - 6.20s
Divide both sides by 1.25 to isolate r
r = (10.55 - 6.20s)/1.25
Therefore, the required expression would be
r = (10.55 - 6.20s)/1.25

what is the equivalent of 3-(-6)
Answer:
3-(-6) = 9

Which statement about the circled digit is true?
F
Its value is 10 times greater than the value of the underlined digit.
G
Its value is the underlined digit - 10.
H
Its value is 70 times the value of the underlined digit.
J
Its value is the underlined digit = 70.
Answer:
Therefore, the correct option is: Its value is 1/10 the value of the underlined digit.
Note: The question is incomplete. The complete question is given below:
2. In the number shown, one digit is underlined and one digit is circled. Which statement about the circled digit is true?
Its value is 10 times greater than the value of the underlined digit.
Its value is 1/10 the value of the underlined digit.
Its value is 70 times the value of the underlined digit.
Its value is 1/70 the value of the underlined digit.
See attachment below for the number
Step-by-step explanation:
This problem is about the place value of whole numbers.
Step 1: Determining the place value of the numbers
The place value is the value of each digit in a number, be it a whole number or a decimal number.
The number shown is seventy seven thousand (77,000)
The place value of the underlined 7 is 7 ten thousands = 7 * 10000 = 70000
The place value of the circled 7 is 7 thousands = 7 * 1000 = 7000
Step 2: Comparing the numbers
Comparing the circled number and the underlined number:
7000/70000 = 1/10
Therefore, the correct option is: Its value is 1/10 the value of the underlined digit.

Answer:
85 messages
Step-by-step explanation:
The system of equations for this is
35 + .10x
18 + .3x
where x = the number of text messages
Usually, you would use substitution or elimination to solve this problem. However, because the answer choices were given, you can just plug in the values.
When you plug in 85, or x = 85, you get 43.5 for both equations because
35 + .10(85) = 43.5 18 + .3(85) = 43.5
Therefore, the answer would be 85 messages becuase both plans will cost the same when you send 85 text messages!

if a sample of 25 students is taken from a population of 179 students the population variance o^2, is the variance of how many students' heights
Answer: 179
Step-by-step explanation:
The population variance cannot be determined solely from a sample, but the sample variance can provide an estimate of it based on the data collected from the sample.
The population variance ) represents the variance of the entire population. In this case, the population consists of 179 students. However, if we take a sample of 25 students from this population, the variance of this sample is called the sample variance
The sample variance ) is used to estimate the population variance ). It is calculated using the following formula:

Find the area under the standard normal curve that lies outside the interval between following two values. Round the answers to at least four decimal places. (a)Find the area under the standard normal curve that lies outside the interval between -1.43 and 1.34.
Answer:
A = 0,16644
Step-by-step explanation:
The area (A₁) under the bell shape curve, from the left tail up to the point ( z score) 1,34 is:
For z (score ) = 1,34 A₁ = 0,9099
The area A₂ from the left tail up to z = -1,43 is
A₂ = 0,07634
Area A₂ is inside area A₁, the area A₃ inside the points - 1,43 and 1,34 is
A₃ = A₁ - A₂
A₃ = 0,9099 - 0,07634
A₃ = 0,83356
Finally area outside the interval - 1, 43 and 1,34 is A ( the area we were looking for) is
A = 1 - A₃
A = 1 - 0,83356
A = 0,16644
