Peter wants to make for necklaces that are the same way. He asked his friends to cut the string for the necklace is 15 paper clips long. With all the links me the same explain your think
Correct question is;
Peter wants to make four necklaces that are the same way. He asked his friends to cut the string for the necklace 15 paper clips long. Would all the lengths be the same? Explain your think
Answer:
No, the lengths would not be the same. This is due to the fact the the paper clips could be in different sizes.
Step-by-step explanation:
We are told that he wants to make four necklaces that are the same way and that he told his friends to cut the string for the necklace 15 paper clips long.
Now, we are not told the sizes of the paper clips and we know that paper clips come in different sizes. Thus the paper clips in which the strings are cut could be in different sizes. Therefore, the lengths wouldn't be the same due to that.
Three more than seven times a number d is equal to fifty nine. What is the value of d?
Answer:
d = 8
Step-by-step explanation
Work Backwards:
59 - 3 = 56
56/7 = 8
Therefore d = 8
Answer:
Three more than seven times a number d is equal to fifty nine
According to the problem
[tex]7d + 3 = 59 \\ 7d = 59 - 3 \\ 7d = 56 \\ d = \frac{56}{7} \\ \boxed{d = 8}[/tex]
Value of d is 8.What do you add to
5 3/7 to make 8?
Answer:
2 4/7
Step-by-step explanation:
3/7+4/7= 7/7 or 1 whole
So you add that to the 5 and get 6, then you need 2 to get to 8 because 6+2=8
Hope this helped!!!
Answer:
2 4/7
Step-by-step explanation:
let n = number to add to 5 3/7
change 5 3/7 to improper fraction: 38
7
change 8 to become 56
7
create equation:
38 + n = 56
7 7
n = 56 - 38
7 7
n = 18 or 2 4/7
7
check: 5 3 + 2 4 = 8
7 7
5 + 2 = 7 and 3/7 + 4/7 = 1
7 + 1 = 8

B.{-6,16,29}
C.{-6,19,29}
D.{14,16,24}
The range of the function will be;
⇒ { - 6, 19, 29 }
What is Domain?The set of all inputs of the function is called Domain of set.
Given that;
The function is,
⇒ f (x) = 5x + 4
And, The domain = {-2, 3, 5}
Now,
Since, The function is,
⇒ f (x) = 5x + 4
We know that;
The range of the function gives the value of f (x).
So, We get;
The function is,
⇒ f (x) = 5x + 4
Put x = - 2;
⇒ f (-2) = 5 × - 2 + 4
= -10 + 4
= - 6
Put x = 3;
⇒ f (3) = 5 × 3 + 4
= 15 + 4
= 19
Put x = 5;
⇒ f (5) = 5 × 5 + 4
= 25 + 4
= 29
Thus, The value of range = { - 6, 19, 29 }

Which polynomial is factored completely?
Completely factored:
(4x+4)(x+1) and 2x(x²-4)
Step-by-step explanation:
We have to check each option one by one, It is sum of two perfect square, As we know sum of two perfect square can't be factored. It is prime equation.
Here we have two factor (4x+4) and (x+1). In both factor degree of x is 1. It is complete factor form. Here we have two factor 4x and x²-4. For second factor it is further factor. Because it is difference of square. Factor of x²-4 = (x+2)(x-2)
Complete Factor: 2x(x+2)(x-2)[/tex],
Here variable are not same. So, it can't be factor (false)

Your weekly base salary is $150. You earn $20 for each phone you taht you sell. The company policy is that as a part-time employee , the maximum you can earn each week is $950
Write and solve an inequality that represents the number of cell phones you can sell each week.
Answer:
You can sell at least 40 phones each week.
Step-by-step explanation:
Given that:
Weekly base salary = $150
Earning on each phone = $20
Maximum amount that can be earned each week = $950
Let,
m be the number of phones.
20m + 150 ≤ 950
20m ≤ 950 - 150
20m ≤ 800
Dividing both sides by 20
[tex]\frac{20m}{20}\leq \frac{800}{20}[/tex]
m ≤ 40
Hence,
You can sell at least 40 phones each week.
Harley had $500 is his account at the beginning of the year. He spends $20 each week on food, clothing, and movie tickets. He wants to have more than $100 at the end of the summer to make sure he has enough money to purchase some new shoes before school starts. How many weeks, w, can Harley withdraw money from his savings account and still have more than $100 to buy the new shoes at the end of the summer?
Answer:
19 weeks
Step-by-step explanation:
Harley has an initial amount in his account = $500
He spends the amount each week = $20
He wants to have more than $100 in his account at the end of summer to purchase some new shoes.
We assume that he can withdraw the money from his account for 'w' weeks,
Inequality representing this situation will be,
(500 - 20w) > 100
Further solving this inequality,
-20w > 100 - 500
-20w > -400
w < 20
Therefore, Harley can withdraw the money for less than 20 weeks or 19 weeks.

using the elimination method how do I find x and y for the following problem:
3x+5y=-1
x + 5y = 4
Answer:
x is equal to -3, and y is equal to eight fifths, or 1.6
Step-by-step explanation:
Solving by elimination means to add or subtract one of the equations from the other, eliminating one of their common terms.
Because both of the provided ones have the term 5y (and no other y terms), let's use subtraction:
3x + 5y = -1
- ( x + 5y = 5 )
2x + 0 = -6
Which we can solve pretty quick:
2x = -6
x = -3
We can now solve either of the original equations for y:
x + 5y = 5
-3 + 5y = 5
5y = 8
y = 8/5, or 1.6
To make sure we're correct, let's test our results in the other equation:
3x + 5y = -1
3 × -3 + 5 × 8/5 = -1
-9 + 8 = -1
-1 = -1
So we're good!

Select the correct answer !!!!!!!!!!HELP OVER HERE!!!!!!!!!!!!
Answer:
-48
Step-by-step explanation:
-56 - -8
Subtracting a negative is like adding a positive
-56 +8
The signs are different so we subtract the two numbers and take the sign of the larger
56 -8 = 48
The larger number has a negative sign so the answer is negative

What is the length of the hypotenuse?
C=
meters
Pythagorean Theorem: a^2 + b^2 = c^2
A and B are the sides given to us, because they're not the hypotenuse. Square each at add them.
That leaves you with 289. Square root it, because we want to find C without being squared.
The square root of 289 is 17, so the hypotenuse is 17 m in length
