Answer:
[tex]A = 52[/tex], [tex]B = 38[/tex]
Step-by-step explanation:
The sum of two complementary angles is always [tex]90[/tex]°
[tex]A + B = 90[/tex]
[tex]A = B + 14[/tex]
substitute [tex]A[/tex] for [tex]B = 14[/tex]
[tex](B + 14)+ B = 90[/tex]
[tex]2B + 14 = 90[/tex]
[tex]2B = 76[/tex]
[tex]B = 38[/tex]
input this into the original equation
[tex]A + 38 = 90[/tex]
[tex]A = 52[/tex]

= 378/2100*100
=0.18*100
= 18%
Hence the percentage commission is 18%
A. Tomás collects sports cards. The number of baseball
cards he buys each week is proportional to the number
of football cards he buys.
B. Suppose Tomas buys a total of 30 seconds baseball and football cards in Week 5. How many of each would he have to buy to keep the same proportional relationship?
Week = 1 | 2 | 3 | 4
NOBC = 9 | 15 | ? | 6
NOFC = 6 | ? | 8 |
NOBC ( number of baseball cards)
NOFC ( Number Of football cards )
what is the answer for this
Answer:
∠B = 141
Step-by-step explanation:
n - > number of sides
n = 7
Sum of all interior angles = (n -2 ) * 180
= 5 * 180 = 900
∠B + 148 + 90 + 142 + 130 + 129 + 120 = 900
∠B + 759 = 900
∠B = 900 - 759 = 141

Deborah spent $70 on food and clothes. She spent $26 more on clothes than on food. On your worksheet, solve the question and write your answer below. How much did she spend on food and how much did she spend on clothes?
Answer:
She spent $22 on food, and $48 on clothes.
Step-by-step explanation:
Let's define the variables:
C = amount of money that Deborah spent on clothes
F = amount of money that Deborah spent on food.
We know that she spent in total $70, then we have the equation:
F + C = $70
And we know that she spent $26 more on clothes than on food, then we have the equation:
C = F + $26
This means that we have a system of equations:
F + C = $70
C = F + $26
To solve these type of systems, we usually start by isolating one variable in one of the equations. Here we can see that C is already isolated in the second equation.
Now we can replace it in the first equation.
F + (F + $26) = $70
Now we can solve this for F.
2*F + $26 = $70
2*F = $70 - $26 = $44
F = $44/2 = $22
So she spent $22 on food.
Now we can use the equation:
C = F + $26
To find how much she spent on clothes, where we need to replace F by the value we found.
C = $22 + $26 = $48
She spent $48 on clothes.

One of the altitudes of the parallelogram shown is StartRoot 22.5 EndRoot units. What is the length of the other altitude?
5 units
6 units
30 units
StartRoot 40 EndRoot units
Answer:
the length of the other altitude of the given parallelogram will be 6 units and option B is the correct choice.
The length of the other altitude in the parallelogram will be B. 6 units.
How to calculate the altitude?The equation to find the altitude in the parallelogram will be:
Altitude 1 × Vertical base = Altitude 2 × Horizontal base
✓22.5 × ✓40 = Altitude 2 × 5
30 = Altitude 2 × 5
Altitude 2 = 30/5
Altitude = 6

Please help me what is a NOW a/4 − 5/6 = −1/2
Answer:
Step-by-step explanation:
Change the denominator of the 1/2 to sixths. Multiply the top and bottom by 3 to get 3/6
[tex]\frac{a}{4}-\frac{5}{6}=-\frac{3}{6} \\[/tex]
Add 5/6 to both sides and simplify
[tex]\frac{a}{4} =\frac{1}{3}[/tex]
Multiply both sides by 4 to get

what is the slope intercept equation for the following line? 
(see image)
Answer:
y = x + 1
Step-by-step explanation:
You can immediately read off the y-intercept from the graph: (0, 1). The slope of this line is negative. Choosing two different points on this line leads to finding the slope of the line: (0, 1) and (2, -1) Going from the first point to the other, we see that x (the run) increases by 2 and y(the rise) decreases by 2. Thus, the slope is m = rise/run = 2/2 = 1.
The slope-intercept equation of this line is therefore y = x + 1.
Answer:
y=-1x+1
Step-by-step explanation:
To find the slope, we can use rise (vertical) over run (horizontal).
m=rise/run
We can see that from the first point to the second point, x increased by 2 and y decreased by 2.
The rise is -2 and the run is 2.
m=2/-2=-1.
The slope is -1.
Now let's find the y-intercept (the point where x=0, or where the line crosses the y-axis.)
This point is at (0,1), so b=1.
The y-intercept is 1.
This is the format for slope-intercept form: y=mx+b.
The slope-intercept equation is y=-1x+1.

Answer:
x = 13
Step-by-step explanation:
1. We can tell if the radical is in its simplest form if the square root term is a number that cannot be broken down to give a perfect square factor
what we are saying in this case is that if the number that is under the square root sign is one in which cannot be broken down to give a perfect square or that a perfect square is not its factor. Then it is in the simplest form

Using the formula we get our answer.
A cable company uses the formula S = 20,000 (1 + 0.08)y to estimate the number
of subscribers, S, that use their service after y years. If there were 20,000 cable
television subscribers when the cable company began, what is the meaning of the
expression (1 + 0.08)Y?
A. Every year the number of subscribers is estimated to increase by 8 over the number
of subscribers the year before.
B. Every year the number of subscribers is estimated to increase by 8% of the original
20,000 subscribers
C. Every year the number of subscribers is estimated to increase by 8% over the
number of subscribers the year before.
D. Every year the number of subscribers is estimated to increase by 80% of the
original 20,000 subscribers.
I
Answer:
C. Every year the number of subscribers is estimated to increase by 8% over the
number of subscribers the year before.
Step-by-step explanation:
Using the formula :
S = 20,000 (1 + 0.08)^y to estimate ;
S = number of subscribers ; y = years
The expression : (1 + 0.08)^y
0.08 = 0.08 * 100% = 8%
(1 + 0.08)^y represents a continous growth or increase in the number of subcsribers by 8% over the number of subscribers the preceeding year
The width of a rectangle is 32 inches. The width of the rectangle decreased by 8 inches and its length also changed. The area of the rectangle remains the same, 1,440 square inches. What is the new length of the rectangle?
Answer:
60 in
Step-by-step explanation:
Area = length x width
Area is constant at 1440 in^2
For first rectangle: W1 and L1
For second rectangle: W2 and L2
W1 = 32 in
W2 = W1 - 8 in = 24 in
1440 in^2 = L1 x 32 in = L2 x 24 in
L1 = 45 in
L2 = 60 in
