The owner of two hotels is ordering towels. He bought 20 hand towels and 76 bath towels for his hotel in Hillsdale, spending a total of $764. He also ordered 75 hand towels and 35 bath towels for his hotel in Lanberry, spending $615. How much does each towel cost? A hand towel costs $ , and a bath towel costs $
Answer:
hand towel = $4
bath towel = $9
Step-by-step explanation:
hotel 1: 20h +76b = $764
hotel 2: 75h + 35b = $615 ----> b = (615 - 75h)/35
plug equation of hotel 2 into equation of hotel 1
20h + 76[ (615 - 75h)/35]
solve to get h =$4
then plug that number into b = (615 - 75h)/35
b = (615 - 75x4)/35
b = 9
As a part of their weather unit, Anoki’s science class took a hot air balloon ride. As they passed over a fenced field, the angle of depression of the closer side of the fence was 32°, and the angle of depression of the farther side of the fence was 27°. If the height of the balloon was 800 feet, estimate the width of the field. Round your answer to the nearest foot.
Hello there!
I hope you and your family are staying safe and healthy!
P.S. I did my best drawing the problem :)
[tex]Tan 32 = \frac{800}{x}[/tex]
[tex]x = \frac{800}{tan32}[/tex]
[tex]Tan 27 = \frac{800}{y}[/tex]
[tex]y=\frac{800}{tan27}[/tex]

Answer:
f(0)=9
Step-by-step explanation:
All you do is plug in x=0 into the function.
In this case:
f(x)=10^x+8
f(0)=10^0+8
f(0)=1+8
f(0)=9
Therefore, f(0)=9
Answer:
9
Step-by-step explanation:
You put 0 for x
10^0=1, so 1 +8 is 9

Carmen needs to order raffle tickets for a company party. Usually, 1 out of 2 employees will
buy a raffle ticket. If there are 500 employees expected at the company party and raffle tickets
come in packages of 15, how many packages of raffle tickets should Carmen order?
Answer:
17
Step-by-step explanation:
500/2 = 250
250/15 = 16.6 repeated
If you round 16.6, you get 17, and it better to have too many, than not enough.

find the coordinates of the midpoint of AB given A (2,3) and B (4, -2)
Answer:
(3, 1/2)
Step-by-step explanation:
The x-coordinate of the midpoint of AB is the arithmetic mean of 2 and 4, which comes out to 3. The y-coordinate of the midpoint of AB is the arithmetic mean of 3 and -2, which comes out to 1/2.
Thus the midpoint of AB is (3, 1/2).

Which of the following sentences is true?
Can you please help me?
Answer:
∠ BAC ≈ 67.4°
Step-by-step explanation:
Using the sine ratio in the right triangle.
sinA = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{BC}{AB}[/tex] = [tex]\frac{12}{13}[/tex] , then
∠ A = [tex]sin^{-1}[/tex] ([tex]\frac{12}{13}[/tex] ) ≈ 67.4° ( to 1 dec. place )

Josh and Lucy share some money.
Josh receives 4/5 of the money.
In what ratio did they share the money? *
(1 Point)
4:9
4:1
1:4
4:5
Answer:
4:1
Step-by-step explanation:
When converting between ratios and fractions, the denominator of the fraction is always the sum of all the numbers in a ratio. So you can eliminate the first (4:9) and last (4:5) answers because 4+9 and 4+5 do not add up to 5.
That leaves you with the middle two answers. Honestly, it could also be 1:4 but since the question talks about Josh receiving the money, the ratio would be 4 parts for him and 1 for Lucy, so 4:1 is probably the correct option

In a right triangle, one of the angles measures 29º. What is the measure of the
other angles in the triangle?
45° and 61°
90° and 42°
90° and 61°
90° and 51°
Answer:
90° and 61°
Step-by-step explanation:
Since it's a right angled triangle, I thought it was wrong since you said right angle.
180 - 29 = 151
There is always one right angle in a right angled triangle, which is 90°, so you just have to deduct 90° and 29° from 180° and you will find out the answer.
180 - 29 - 90 = 61°

The graph below shows a transformation of the shaded rectangle onto the unshaded rectangle. On a coordinate plane, a shaded rectangle is larger than the unshaded rectangle. Keesha says the transformation is a translation, but Teagan says that the transformation is a dilation. Which statement about the transformation is true? Keesha is correct because the shaded rectangle is moved vertically to make the unshaded rectangle. Keesha is correct because the shaded rectangle is flipped across a horizontal line. Teagan is correct because the unshaded rectangle is smaller than the shaded rectangle. Teagan is correct because the unshaded rectangle is turned in a clockwise direction.
Answer:
C.) Teagan is correct because the unshaded rectangle is smaller than the shaded rectangle.
Step-by-step explanation:
Teagan is correct because the unshaded rectangle is smaller than the shaded rectangle.
What is a Shaded area in a graph?In a graph showing an inequality system, shading above and below denote larger than and less than, respectively. The region's boundary should also be taken into consideration; a solid line denotes equality, while a dashed line denotes non-equality.
In geometry, a function known as translation is one that simply moves an object a predetermined distance without changing it in any way. The object must be moved with each point traveling the same distance and in the same direction. While dilation is a transformation that results in a smaller version of the original thing. A scale factor and a set location in the plane known as the center of the dilatation are needed.
So, when comparing the two shapes, dilation is the transformation. Because the unshaded rectangle is smaller than the shaded area, Teagan is correct.
