Alyssa used a can of paint that was 5/6 full to touch paint her house. When she was done, the bucket was 11/30 full. What fraction of the can did she use?
Answer:
7 / 15
Step-by-step explanation:
Fraction before painting = 5/6
Fraction left after painting = 11/30
Fracrion used = difference of the fraction before painting and fraction left after painting
Fraction used = 5/6 - 11/30
Lowest common factor of 6 and 30 = 30
5/6 - 11/30 = (25 - 11) / 30 = 14/ 30
Fraction used = 14/30 = 7/15
In ΔWXY, the measure of ∠Y=90°, XW = 89, WY = 80, and YX = 39. What ratio represents the cosine of ∠X?
Answer:
It's 39/89
Step-by-step explanation:
cos X = adjacent/ hypotenuse = 39/89
[tex]\frac{39}{89}[/tex] represents cosine of ∠X.
What is cosine?
'In a right-triangle, cos is defined as the ratio of the length of the adjacent side to that of the longest side which is the hypotenuse.'
According to the given problem,
In the right angle triangle ΔWXY,
Hypotenuse = XW = 89
Perpendicular = WY = 80
Base = YX = 39
We know,
cos∅ = [tex]\frac{Base}{Hypotenuse}[/tex]
⇒ cosX = [tex]\frac{39}{89}[/tex]
Hence, we can conclude that the ratio [tex]\frac{39}{89}[/tex] represents the cosine of ∠X

Which equation matches the graph?
In the xy graph, the range of the x axis is zero to four by increment of one. The range of y axis is zero to eight by increment of one. On both axes every alternate tick mark is labeled. On the graph, there is a line passing through the points (2, 2) and (0, 8).
Answer:
[tex]y = -3x +8[/tex]
Step-by-step explanation:
The graph diagram is not given; however, the equation can be solved from the given points
(2,2) and (0,8)
This is represented as:
[tex](x_1,y_1) = (2,2)[/tex]
[tex](x_2,y_2) = (0,8)[/tex]
Calculate slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{8 - 2}{0 - 2}[/tex]
[tex]m = \frac{6}{- 2}[/tex]
[tex]m =-3[/tex]
The equation is calculated using:
[tex]y - y_1 = m(x - x_1)[/tex]
[tex]y - 2 = -3(x - 2)[/tex]
[tex]y - 2 = -3x + 6[/tex]
Add 2 to both sides
[tex]y - 2 +2= -3x + 6+2[/tex]
[tex]y = -3x + 6+2[/tex]
[tex]y = -3x +8[/tex]

more. How much does Ray's puppy weigh now? Explain using pictures,
numbers, or words.
Answer:
Puppy's current weight = 33 pounds.
Step-by-step explanation:
The weight of Ray's puppy 1 year ago = 8 pounds
Now, his puppy weighs 25 pounds more.All we need is to add the 8 pounds to 25 to determine the current weight.
i.e.
current weight = 8 + 25
= 33 pounds

What is 116.52 plus 8% as tax
Answer:
125.84
Step-by-step explanation:
116.52(0.08)=9.32
116.52+9.32=125.84
Answer:
The total is $125.84.
Step-by-step explanation:
The total is equal to the original value (100%) + the tax amount (8%) which equals 108%. To multiply it, we move the decimal two to the left to get our figure (1.08) then multiply that times 116.52. So, 116.52x1.08=125.8416; for dollars I rounded to the nearest cent: $125.84.

A piece of paper has a rectangle ABCD in which AB= 10 cm and BC = 22 cm , it was folded to form a right circular cylinder such that AB is cincident to DC . Find the volume of the resulted cylinder
Answer: [tex]385cm^{2}[/tex]
Step-by-step explanation:
given data:
AB= 10 cm.
BC = 22 cm.
volume of a cylinder V = [tex]\pi r^{2} h[/tex]
h = 10.
solution
base of the circumference = 22cm
circumference of a circle = [tex]2\pi r[/tex]
r = radius is unknown.
[tex]2\pi r = 22[/tex] .........................eq1
where [tex]\pi = \frac{22}{7}[/tex] insert this into eq1.
[tex]2* \frac{22}{7}* r = 22[/tex]
[tex]\frac{44}{7} r = 22[/tex]
[tex]r = \frac{22}{\frac{44}{7} }[/tex]
[tex]r= 3.5cm[/tex]
next we solve for the volume of the cylinder.
recall [tex]V = \pi r^{2} h[/tex]
h = 10cm
r = 3.5cm
[tex]V = \frac{22}{7} * (3.5)^{2} *10[/tex]
[tex]V = 385cm^{2}[/tex]
Pleaseeee helpppp !!!!!!!! Will mark Brianliest !!!!!!!!!!!!!
Answer:
These are similar triangles.
By changing the length of the base of the corresponding triangle, the 3 interior angles of this triangle remain equal to the original
Therefore, if these triangles are similar, their corresponding sides must give equal ratios to each other:
This means that BF/FE = BC/CD=FC/ED
The total length of line segment BD=BC+CD; BC=6, CD=42; BD=6+42, BD=48
BE=BF+FE; BE=9+?
if BF/FE=BC/CD then 9/BE=6/42; 6/42=3/21 or 1/7. 9/BE=1/7; 1/7=9/BE
1x9=9, 7x9=63
63=BE
Step-by-step explanation:
Answer:BE is equal to 72.
Step-by-step explanation: They are similar triangles. We know CD and BC. So we can find the comparison between the two. And we see that BC x 7 = CD. So the same will be said for BF and FE. We have BF is equal to 9. So 9 x 7 = 63. However, now we need to add the two together in order to get BE. Because BF + FE = BE. So 9 + 63 = 72

2. A solar lease customer built up an excess of 6,500 kilowatt hours (kwh) during the summer using his solar
panels. When he turned his electric heat on, the excess began to be used up at a rate of 50 kilowatt hours
per day.
(a) If E represents the excess left and d represents (b) How much of the excess will be left after one
the number of days since the heat has been month (use a month length of 30 days)?
turned on, write an equation for E in terms of d.
(c) If the heat will need to be turned on for 5 months, will the excess be enough to last through this time
period? Justify your answer.
9514 1404 393
Answer:
a) E = 6500 -50d
b) 5000 kWh
c) the excess will last only 130 days, not enough for 5 months
Step-by-step explanation:
Given:
starting excess (E): 6500 kWh
usage: 50 kWh/day (d)
Find:
a) E(d)
b) E(30)
c) E(150)
Solution:
a) The exces is linearly decreasing with the number of days, so we have ...
E(d) = 6500 -50d
__
b) After 30 days, the excess remaining is ...
E(30) = 6500 -50(30) = 5000 . . . . kWh after 30 days
__
c) After 150 days, the excess remaining would be ...
E(150) = 6500 -50(150) = 6500 -7500 = -1000 . . . . 150 days is beyond the capacity of the system
The supply is not enough to last for 5 months.

Simplify the expression. -2.5f + 0.4f - 14 - 3?
Answer:
-2.1f-17
Step-by-step explanation:
combine like terms
Answer:
-2.1f-17
Step-by-step explanation:
1. Combine like terms
Like terms are those that either have the same variable, degree, or no variable at all.
Here, -2.5f and 0.4f and -14 and -3 are like terms. -2.5f and 0.4f are like terms because they both have f beside them. The reason -14 and -3 are like terms is because they both stand alone with no variables.
Combining like terms means to either add or subtract them from each other depending on their signs.
Just think of them as two separate problems for now.
-2.5f + 0.4f = ?
add these two together to get -2.1f
-14-3
Subtract these to get -17.
2. Put the expression back together: -2.1f-17

Her house is at (−4, 10). Her school is at (−4, 3). The community center is at (2, 3). The grocery store is at (−4, −6). Part A: Use absolute values to calculate the distance in units from Nina's house to her school
Answer:
7 units
Step-by-step explanation:
Given that :
house is at (−4, 10). Her school is at (−4, 3)
House location = (-4, 10)
School location = (-4, 3)
Distance from house to school (d) :
Distance between two points :
x = sqrt[(x2 - x1)^2 + (y2 - y1)^2]
x1 = - 4 ; y1 = 10 ; x2 = - 4 ; y2 = 3
d = sqrt[(-4 - (-4))^2 + (3 - 10)^2]
d = sqrt[(-4 + 4)^2 + (-7)^2]
d = sqrt(0 + (-7)^2)
d = sqrt(49)
d = 7 units

Answer:
The composite area is a total of 62 square inches.
Step-by-step explanation:
You're given three rectangles of different width and height. To find the correct answer, you need to find the sum of each rectangles' area.
first though we need to find the height of the middle rectangle. We are told the total height and the other two rectangles' heights, so we just need to subtract the others' heights from the total:
10 - (4 + 1.5)
10 - 5.5
= 4.5
So the middle rectangle is 4x4.5 inches, giving it an area of 18 square inches
The top one is 8x4 inches for a total of 32 square inches.
And the bottom one is 1.5x8 inches, for a total 12 square inches.
If we add them all up, that's 18 + 32 + 12 square inches, or 62 square inches.
