Answer:
n = 2.6
Step-by-step explanation:
Hello!
We can create an equation with equivalent fractions. Remember that a ratio can also be represented as a fraction.
[tex]a:b = \frac ab[/tex]We can create two fractions that are equivalent to each other given the ratios.
[tex]\frac{15}{39} = \frac 1n[/tex]Solve for n[tex]\frac{15}{39} = \frac 1n[/tex][tex]\frac{5}{13} = \frac 1n[/tex][tex]5n = 13[/tex][tex]n = \frac{13}{5}[/tex][tex]n = 2.6[/tex]The value of n is 2.6.

Answer:
32 m^2
Step-by-step explanation:
First find the volume of the bottom section
V = l * w*h
V = 6 * 2 * 2 = 24 m^2
Then find the volume of the top section in green
The length is 6-4 =2, the height is 4-2, width is 2
V = = l*w*h = 2*2*2 = 8
Ad the volumes together
V = 24+8 = 32 m^2

Two triangles can be formed with the given information. Use the Law of Sines to solve the triangles
A = 59°, a = 13, b = 14
Answer:
67.4°, C = 53.6°, c = 12.2; B = 112.6°, C = 8.4°, c = 2.2
a/sinA=b/sinB=c/sinC
a/sinA=13/0.8572=15.1662
sinB=b/a *sinA
sinB=14/13 *sin59=0.9231
B=67.4
B1=90+22.6=112.6
because sin67.4=sin112.6=0.9231
C=180-59-67.4=53.6
C1=180-59-112.6=8.4
c=a* sinC/sinA=13* sin53.6/sin59=12.2
c1=a* sinC1/sin59=13*sin8.4/sin59=2.2
what is the diagonal of a solid square. the sides are 7. please help
Answer:
9.89949 units
Step-by-step explanation:
the diagonal of a 7 by 7 square is the same as the hypotenuse of a 7 by 7 triangle. using the pythagorean theorem, you can conclude that
7²+7²=c²
49+49=c²
98=c²
√98=c
c≈9.89949 units
Given the slope and one point on the line:
m = -2
(7,-3)
Write the linear equation in standard form:
Answer:
y= -2x + 11
Step-by-step explanation:
standard form for lines is y=mx+b
m is the slope and b is the y intercept
we already know that m is -2, so we just need to figure out the intercept.
the point given is (7,-3)
points are written as (x,y) so we can plug it into the equation with 7 for the x and -3 for y
-3 = -2 (7) + b
-3 = -14 + b
11 = b
so the equation is y=-2x+11

Can anyone help me with this please .
Answer:
Left: yes it is linear
Right: No it is not.
Step-by-step explanation:
Left Problem
The table on the left is linear. It's general form is
y = 6x + 7
x = 5
y = 5*6 + 7
y = 37
-------------------
x = 8
y = 6*8 + 7
y = 48 + 7
y = 55
------------------
y = 6*12 + 7
y = 72 + 7
y = 79
=============
Right Problem
The right problem looks like it is linear. It is not, I don't think. Do the same thing you did above.
y = 62x
x = 2
y = 2*62
y = 124
-----------------------
y = 62x
x = 6
y = 62 * 6
y = 372
---------------------
y = 62*x
x = 9
y = 62 * 9
y = 558
It should be 558 not 552
For a company picnic, Vijay ordered a box of fresh-baked gingerbread cookies and sugar cookies. He got 70 cookies in all. 28 of the cookies were gingerbread. What percentage of the cookies were gingerbread?
Answer: 40%
Step-by-step explanation:
There are 70 cookies in total.
The gingerbread cookies number 28.
The percentage that are gingerbread will therefore be:
= Number of gingerbread/ Total number of cookies * 100%
= 28 / 70 * 100%
= 40%

A sweatshirt manufacturer includes a shipping charge of $5.99 on all online orders. Customers also pay 2.5% tax on all their purchases. There is a linear equation between c, the cost of of the items purchased, and t, the total cost of including shipping and tax. Which statement is true about the function that represents the relationship between c and t. Brainly
Answer:
t = 1.025c + 5.99
Step-by-step explanation:
The shipping charge, = $5.99
Tax paid on purchases = 2.5%
Cost of item, c
Total cost, t, including shipping and tax
Total cost = Cost of item + tax on purchase +. Shipping fee
Tax on purchase : 2.5% * cost of item
Tax on purchase : 0.025c
Shipping = $5.99
General formula for a linear equation :
y = mx + c
Hence, for the cost model:
Total cost = Cost of item + tax on purchase +. Shipping fee
t = c + 0.025c + 5.99
t = 1.025c + 5.99

Zahn takes a summer job selling ice cream bars at the pool. He receives a fixed salary and then additionally a commission for each ice cream bar he sells. The table shows Max's total earnings, y, in dollars, from selling x ice cream bars:
Ice Cream Sales and Earnings
Number of Bars Sold (x)
Total Earnings (dollars) (y)
0
30
1
34
2
38
3
42
Select the equation that best represents the relationship between x and y. (5 points)
a
y = x + 34
b
y = 4x + 30
c
y = 4x + 42
d
y = x + 42
Answer: B
If you look at the table, you notice that he earns 30 without selling ice cream bars. This is his fixed salary.
When he sells one ice cream bar, he earns 34, which means he gets 4 dollars for each bar he sells.
The equation that best represents the relationship between x and y is b) y = 4x + 30, because 4 dollars × number of ice cream bars + fixed salary equals his total earnings.

The table below shows the monthly balances a person had on their credit card over a five-month period.
Month Balance
January -$50
February $25
March -$70
April -$45
May $25
What was the average monthly balance over the five-month period? Enter your answers and your explanations or work in the space provided.
Answer:
average monthly balance = $43
Step-by-step explanation:
If we have a set of N numbers:
{x₁, x₂, x₃, ..., xₙ}
The mean (or average) is calculated as:
Mean = (x₁ + x₂ + ... + xₙ)/N
In this case, the values on the set are the balances for every month.
Then our set is:
{$50, $25, $70, $45, $25}
This is a set of 5 elements.
Then the average monthly balance is:
average monthly balance = ($50 + $25 + $70 + $45 + $25)/5 = $43
average monthly balance = $43
what is the solution to the inequality -x/10>-11
Answer:
x<110
Step-by-step explanation:
-x/10>-11
-x>-11*10
-x>-110
x>110
x<110
Answer:
x > - 110
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the greater than a sign from both sides of the inequality :
x / 10 - ( -11 ) > 0
x
Simplify ——
10
x
—— - -11 > 0
10
Subtracting a whole from a fraction
Rewrite the whole as a fraction using 10 as the denominator :
-11 -11 • 10
-11 = ——— = ————————
1 10
Equivalent fraction: The fraction thus generated looks different but has the same value as the whole
Common denominator: The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
x - (-11 • 10) x + 110
——————— = ———————
10 10
x + 110
——————— > 0
10
Multiply both sides by 10
Subtract 110 from both sides
x > -110

Moira swims 3/6 hour before school 5 days a week and 5/6 hour after school 4 days a week. For how long does she swim each week?
9514 1404 393
Answer:
5 5/6 hours
Step-by-step explanation:
We can add the times, but it is more convenient to use multiplication.
5(3/6) + 4(5/6) = (15/6) +(20/6) = 35/6 = 5 5/6
Moira swims 5 5/6 hours each week.
Find the volume of a right circular cone that has a height of 18 m and a base with a
radius of 5.8 m. Round your answer to the nearest tenth of a cubic meter.
Answer:
V=634.0 cubic meter.
Step-by-step explanation:
By formula V=πr^2(h/3)
so V=π5.8^2(18/3)
then 5.8square2 =33.64 ,18/3=6 and pi
multiply everything you'll get V=634.0990612
finally it says round to the nearest tenth which mean , V=634.0 cubic meter.

To make some extra money over the summer, Kelsey and Olivia got jobs mowing the 5 acres of grass at the local park. Each week, the girls worked together to mow all the grass, splitting it equally. How many acres did each girl mow each week?
Answer:
Area covered by each girl = 2.5 acre
Step-by-step explanation:
Given:
Number of girls = 2
Total area = 5 acre
Find:
How much area covered by each girl
Computation:
Area covered by each girl = Total area / Number of girls
Area covered by each girl = 5 / 2
Area covered by each girl = 2.5 acre

Notice that the square root is accompanied with ^2 and can be simplified:
This works because 4x^4 = (2x^2)^2
[tex]\sqrt{(2x^{2})^{2} * (256y^{8})^{2} }[/tex]
Remove the square root:
[tex]2x^{2} (256y^{8} )[/tex]
