Answer:
Step-by-step explanation:
ntroduction. Percent, p%
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100
80% = 80/100 = 80 ÷ 100 = 0.8
100% = 100/100 = 100 ÷ 100 = 1
Percentage of 80% of what number = 40?
80% of what number = 40 is equivalent to:
80% × ? = 40
80% × ? = 40
? =
40 ÷ 80% =
40 ÷ (80 ÷ 100) =
(100 × 40) ÷ 80 =
4,000 ÷ 80 =

Solve for x
Answer:
x = 156
Step-by-step explanation:
These angles are supplementary so they add up to 180:
x - 5 + 29 = 180
x + 24 = 180
x = 156
Answer:
x = 156
Step-by-step explanation:
The line equals 180 degrees, and the angle 29 degrees is already given.
180-29 = 151
This means that the other angle must be 151 degrees.
(x - 5)°
If we replace 156 with x, we will get 151 degrees, so that means x = 156.
(156 - 5)° = 151°

True or false: The cross section of a 3D object may look different depending on the direction (horizontal or vertical) of the cut.
Options:
True
False
True, as there is no guarantee that it will be symmetrical.
What is Geometry?Geometry is defined as the study of two-dimensional or three-dimensional figures like quadrilaterals, Triangles, circles their sides, and angles.
Symmetry is defined as if the object is cut by its center line the two cut parts should be the mirror image of each other so that we can call them symmetric to each other.
Depending on the cut's direction (horizontal or vertical), a 3D object's cross-section may appear differently.
Therefore, the given statement is true that the cross-section of a 3D object may look different depending on the direction (horizontal or vertical) of the cut.

Step-by-step explanation:
Jade buys a blouse and a skirt for 34 of their original price. She pays a total of $31.50 for the two items. If the original price of the blouse is $18, what is the original price of the skirt?
Part A
Which equation represents the situation?
0.75s = 31.50
34(18s) = 31.50
0.75(s + 31.50) = 18
34(18 + s) = 31.50
Part B
Use the Distributive Property to solve the equation.
Enter your answer in the box.
$
Answer:
`Part A:
D. 3/4(18 + s) = 31.50
Part B:
$36
Step-by-step explanation:
I think 34 is 3/4, is that right?
here, s is the cost of the skirt
Part A: The answer would be:
3/4(18) + 3/4(s) = 31.5 =
3/4(18 + s) = 31.5
Part B: 3/4(18) + 3/4(s) = 31.5
4.5 + 3/4s = 31.5
Subtract 4.5 from both sides:
3/4s = 27, 27 is the cost of the skirt now, but we need the original price.
multiply both sides by 4/3:
s = 36

For a school fundraiser, Elena will make T-shirts. She will order T-shirts and print graphics on them. Elena must spend $350 on a printing machine and $5.50 per shirt for the blank shirts, ink, and other supplies. How many T-shirts can she make with $1175?
Answer:
Elena can make 150 t-shirts
Step-by-step explanation:
Find the amount after she buys the printing machine. $1,175-$350=$825Divide by the cost per t-shirt $825÷$5.50=150 t-shirtsFinal answer: 150 t-shirtsFind the x-intercept of the function y=−0.2x+0.55
Answer:
2.75
Step-by-step explanation:
y=0
−0.2x+0.55=0
0.2x=0.55
x=2.75
Answer:
x=-2.75
Step-by-step explanation:
Plug y=0 into the equation and solve for x:
y=-0.2x+0.55
0=-0.2x+0.55
-0.55=0.2x
-2.75=x
Therefore, x=-2.75

cos theta = ------------------- = 18/20. Find theta:
hypotenuse
theta = arccos 18/20 = 0.451 radian.
Now use the sine function to find x:
x x
sin 0.451 radian = ------------------- = ------------- = 0.651
hypotenuse 20
which results in x = 20(0.651) = 13.02
x = 13.02 units
I should have used the Pythagorean Theorem up front.
18² + x² = 20² becomes x² = 400 - 324 = 76, and so x = √76 ≠ 8.72

A. X/6=4/18
B. X/6=18/4
C. X/18=6/4
D. X/4=18/6
E. 4/6=18/X
Step-by-step explanation:
Let x be the number of logs=18 hours
6 logs=4 hours
X*4=18*6
4x=108
x=27 logs
so therefore 27 logs are needed to keep the fire burning for 18 hours
