Answer:
6.5%
Step-by-step explanation:
Hope that helped! =)
Since the bottom number is in the thousands that is why the percent is smaller. and since 65/100 will represent that in the hundredths the bigger the bottom number, just know the top number of it no matter if it is a 75 or 86 it will always be smaller.
someone please help!! find the value of y in this triangle
Answer:
30
Step-by-step explanation:
Triangle containing 120° and y° is an isosceles triangle.
Therefore,
y° + 120° + y° = 180°
2y° = 180° - 120°
2y° = 60°
y° = 60°/2
y ° = 30°
y = 30

Sarah and 9 of her friends went to the movies. They each bought the popcorn, soda and Twizzlers. The popcorn was $6.25, the soda was $2.29 and the Twizzlers were $3.75. How much did they spend in all
Answer:
$122.9
Step-by-step explanation:
Given data
total number of people= sarah+ 9 of her friends= 10 people
Items bought
popcorn= $6.25*10= 62.5
soda= $2.29*10= 22.9
Twizzlers=$3.75*10=37.5
Total = 62.5+ 22.9+37.5= $122.9
Hence the total spent = $122.9

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 coordinate pairs is a point on the line y = -2/5x + 4?
A.) (2, 3)
B.) (-5, 6)
C.) (6, 2)
D.) (-2/5, 4)
Answer:
B.) (-5, 6)
Step-by-step explanation:
to solve algebraically, test the coordinate pairs in the equation [tex]y = -\frac{2}{5}x + 4[/tex]
to solve graphically, enter the equation [tex]y = -\frac{2}{5}x + 4[/tex] into a graphing calculator and graph the coordinate pairs as well to see which one is on the line.
(2, 3) is NOT a solution.
steps for solving algebraically:
first, identify the x and y values in your coordinate pair.
2 is the x-value and 3 is the y-value. coordinate pairs are always written as (x, y).plug in 2 for x in [tex]y = -\frac{2}{5}x + 4[/tex] (it doesn't matter if you plug in x or y first, i personally always start with the x-value but it really doesn't matter what order you do it in.)
y = -2/5x + 4 ⇒ y = -2/5(2) + 4now plug in 3 for y.
y = -2/5(2) + 4 ⇒ 3 = -2/5(2) + 4your equation is now 3 = -2/5(2) + 4. begin simplifying by multiplying -2/5 and 2.
3 = -2/5(2) + 4 ⇒ 3 = -0.8 + 4 (i converted my answer to a decimal because i'm better at dealing with decimals as opposed to fractions lol)now add -0.8 + 4 to simplify the rest of the right side of the equation.
3 = -0.8 + 4 ⇒ 3 = 3.23 and 3.2 are not equal, therefore (2, 3) is not a solution.
(-5, 6) IS a solution.
steps for solving algebraically:
first, identify the x and y values in your coordinate pair.
-5 is the x-value and 6 is the y-value. coordinate pairs are always written as (x, y).plug in -5 for x in [tex]y = -\frac{2}{5}x + 4[/tex] (it doesn't matter if you plug in x or y first, i personally always start with the x-value but it really doesn't matter what order you do it in.)
y = -2/5x + 4 ⇒ y = -2/5(-5) + 4now plug in 6 for y.
y = -2/5(-5) + 4 ⇒ 6 = -2/5(-5) + 4your equation is now 6 = -2/5(-5) + 4. begin simplifying by multiplying -2/5 and -5.
6 = -2/5(-5) + 4 ⇒ 6 = 2 + 4now add 2 + 4 to simplify the rest of the right side of the equation.
6 = 2 + 4 ⇒ 6 = 66 and 6 are equal, therefore (-5, 6) is a solution.
although we have identified (-5, 6) as a solution, i'm still going to check the rest of the points just to be sure! :)
(6, 2) is NOT a solution.
steps for solving algebraically:
first, identify the x and y values in your coordinate pair.
6 is the x-value and 2 is the y-value. coordinate pairs are always written as (x, y).plug in 6 for x in [tex]y = -\frac{2}{5}x + 4[/tex] (it doesn't matter if you plug in x or y first, i personally always start with the x-value but it really doesn't matter what order you do it in.)
y = -2/5x + 4 ⇒ y = -2/5(6) + 4now plug in 2 for y.
y = -2/5(2) + 4 ⇒ 2 = -2/5(2) + 4your equation is now 2 = -2/5(6) + 4. begin simplifying by multiplying -2/5 and 6.
2 = -2/5(6) + 4 ⇒ 2 = -2.4 + 4 (i converted my answer to a decimal because i'm better at dealing with decimals as opposed to fractions lol)now add -2.4 + 4 to simplify the rest of the right side of the equation.
2 = -2.4 + 4 ⇒ 2 = 1.62 and 1.6 are not equal, therefore (6, 2) is not a solution.
(-2/5, 4) is NOT a solution.
i see that they want to trick you with this one by using the values that are in other spots in the equation... that's crafty
steps for solving algebraically:
first, identify the x and y values in your coordinate pair.
-2/5 is the x-value and 4 is the y-value. coordinate pairs are always written as (x, y).plug in -2/5 for x in [tex]y = -\frac{2}{5}x + 4[/tex] (it doesn't matter if you plug in x or y first, i personally always start with the x-value but it really doesn't matter what order you do it in.)
y = -2/5x + 4 ⇒ y = -2/5(-2/5) + 4now plug in 4 for y.
y = -2/5(-2/5) + 4 ⇒ 4 = -2/5(-2/5) + 4your equation is now 4 = -2/5(-2/5) + 4. begin simplifying by multiplying -2/5 and -2/5.
4 = -2/5(-2/5) + 4 ⇒ 4 = 0.16 + 4 (i converted my answer to a decimal because i'm better at dealing with decimals as opposed to fractions lol)now add 0.16 + 4 to simplify the rest of the right side of the equation.
4 = 0.16 + 4 ⇒ 4 = 4.164 and 4.16 are not equal, therefore (-2/5, 4) is not a solution.
as for finding the solution on a graph, enter the equation for the line as well as the coordinate pairs into a graphing calculator. here i used a handy little site called desmos in order to graph all of this. the first photo i attached contains what i entered into the calculator, and the second photo i attached shows the graph. as you can see, the only point that is actually on the line is (-5, 6), which is why (-5, 6) is a solution to [tex]y = -\frac{2}{5}x + 4[/tex] , and the other coordinate pairs are not solutions to that equation because they are not on the line.
i hope this helps! have a lovely rest of your day <3

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
If Susie paid $614 in taxes on gross income of $3,038 what percent of her gross pay is being taken out in taxes
Answer:
the percentage of her gross pay taken out in taxes is 20.21%
Step-by-step explanation:
The computation of the percentage of her gross pay taken out in taxes is as follows:
Given that
Tax paid = $614
And, the gross income is $3,038
So, the percentage is
= $614 ÷ $3,038 × 100
= 20.21%
Hence, the percentage of her gross pay taken out in taxes is 20.21%

3.3+8.6>6.6 is true
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.

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
