Step-by-step explanation:
Answer:
8 $20 bills
13 $100 bills
Step-by-step explanation:
x=# of $20 bills
y=# of $100 bills
x+y=21 --> y=-x+21
20x+100y=1460
20x+100(-x+21)=1460
20x-100x+2100=1460
-80x=-640
x=8
-8+21=13

Write the equation of a line that is perpendicular to Y= 4 and that passes through (7,2)
Answer:
x = 7
Step-by-step explanation:
y = 4 is a horizontal line that passes through the point (0, 4).
A line perpendicular to y = 4 is a vertical line.
In a vertical line, all points have the same x-coordinate.
Since the point (7, 2) is on the vertical line we want, and its x-coordinate is 7, then x-coordinate of all the points on the line we want is 7.
Answer: x = 7

A. Yes; the triangles are congruent by AAS.
B. Yes; the triangles are congruent by ASA.
C. Yes; the triangles are congruent by SAS.
D. No; the triangles are not congruent.
Answer:B. Yes; the triangles are congruent by ASA.
Step-by-step explanation:
In triangle ACD and CAB, AB || CD and AC ≅ BD, B. Yes; the triangles are congruent by ASA.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
We know two similar planer figures are congruent when we have sides or angles or both that are the same as the corresponding sides or angles or both.
Given,
In triangle ACD and CAB, AB || CD and AC ≅ BD.
Therefore, The triangles ACD and CAB are congruent by ASA as ∠A is congruent to ∠C, Side AB is congruent to side CD and ∠B is congruent to ∠B.

What is the measure of the third angle of a triangle if one angle measures 35 degrees and the second angle measures 40 degrees?
Step-by-step explanation: It's important to understand that the sum of the measures of the interior angles of a triangle is always 180 degrees.
So let's first add up the measures of the two angles we know.
So we have 30 + 4 which is 75 degrees.
The missing angle will be equal to 180 minus 75.
So the missing angle measure is 105 degrees.

Consider a square whose sides are of length x. Draw the largest circle that is completely contained within the square. Find the area of the region that is inside the square and but not inside the circle. Express your answer in terms of x and any other mathematical constants that may be necessary.
Answer:
A₁ = x²* ( 1 - π /2) square units
Step-by-step explanation:
Let´s call the area of the region that is inside the square but not inside the circle A₁
And the area of the square A(s)
And the area of the circle A(c)
Then the area we are looking for is:
A₁ = A(s) - A(c)
If the circle has a radius r then
A(c) = π*r²
A(s) = x²
In the square diagonal of the square is d = √ x² + x² ; d = √2 * x
Half of this distance is d/2 = (√2 /2)*x
There is a right triangle with points:
o The center of the square (which is the center of the circle)
a Any of the corners of the square
b Middle point of a side of the square
According to that
r the radius of the circle is:
r² + (x/2)² = (d/2)²
r² + (x/2)² = [ (√2 /2)*x]²
r² = (2/4)*x² - x²/4
r² = (x²/2) - x² / 4
r² = (1/2)*x²
r = x/√2
Then the area of the circle is
A(c) = π * r²
A(c) = π * x²/2
And A₁ = x² - π * x²/2
A₁ = x²* ( 1 - π /2) square units or A₁ =[ ( 2 - π)/2 ]*x²

The table below shows the commission for selling cameras in a
shop for one month.
For the first 20 cameras
$150 total
For every additional camera
$15 per camera
John received a $1,110 commission by selling cameras last
month. How many cameras did he sell last month?
cameras
Answer:
84
Step-by-step explanation:
You first do 1,110-150= 960 dollars.
Then you divide 960 by 15 dollars = 64 cameras
So the first 20 cameras plus the 64 cameras equal 84 cameras.

Answer:
y= 125
Step-by-step explanation:
You can find all the other angles knowing a straight line is equal to 180 degrees. The middle pentagon all adds up to 540 degrees. Once you've found the other sides add them all up and subtract 540 from it and you get 55. Now you do 180-55 one last time to give you y and Y = 125
Answer: y = 125°
Step-by-step explanation:
1) As shown in the picture, I drew a circle for every intersecting point that indicated it would sum up to 360 degrees, so I could find the degrees inside the pentagon.
2) When I had all of the degrees inside the pentagon (except for the corner in the far right), I added all of them together to the sum of 485 degrees.
3) Since all of a pentagon's angles need to add up to 540°, I was left with this equation: 485° + __ = 540°
4) To find the last degree of the pentagon or fill in the blank, I subtracted 540° and 485° to get 55°. The degree in the far right of the pentagon was 55° degrees.
5) I had 55° and 180° to answer what y was. Then again, the circle of intersected lines should all add up to 360°. To get y, I added 55° and 180° to get 235° -- and subtracted 360° and 235° to get 125°.
6) Then, my final answer: y is 125°.

Jordon is mixing water and flour to make a tortilla. The number of cups of water, W needed F cups of flour is described by the equation w= 0.75f
Complete question :
Jordan is mixing water and flour to make tortillas. The number of cups of water, w, needed for f cups of flour is described by the equation w = 0.75f
How many cups of water are needed to mix with 4 cups of flour?
Answer:
3
Step-by-step explanation:
Given the relation :
w = 0.75f
Where w = number of cups of water ; f = cups of flour
Cups of water needed to mix 4 cups of flour :
f = 4
w = 0.75(4)
w = 3
Hence, 3 cups of water is required to mix 4 cups of flour.
