A $120 wagon is on sale for 15 percent off. What is the sale price of the wagon?
$18
$102
$105
$108
Answer:
The answer is $102.
Step-by-step explanation:
The main question here is, what is the sale price of the wagon?
1. Let's compute for 15% of 120.
15%×12015/100×1203/20×1203×6182. So now let us subtract 18 from 120.
You should get 102.Hope this helps and if you could mark this as brainliest. Thanks!
The required sale price of the wagon is $102. So the correct answer is an option (b).
What is the percentage?The percentage is the ratio of the composition of value to the overall composition of value multiplied by 100.
Here, to calculate the sale price of the wagon, we need to find out the discount amount first, and then subtract it from the original price.
Discount amount = 15% of $120
= 0.15 x $120
= $18
Sale price = Original price - Discount amount
= $120 - $18
= $102
Therefore, the sale price of the wagon is $102. So the correct answer is an option (b).

A card is drawn from a standard deck of 52 cards. What is the probability this card will be a king or an ace?
A. about 3.9%
B. about 7.7%
C. about 15.4%
D. about 50%
Answer:
C. about 15.4%
Step-by-step explanation:
There are 52 cards in a deck
There are 4 kings and 4 aces
so, 8/52 is the chance of getting either of those two.
8/52 is about 0.1538 or 15.38%
15.38% rounded would be 15.4%

what is the slope of each side of the triangle? the sides are A(-2,4) B(-1,1) C(2,3)
Answer:
The slopes of three sides of triangle are as follows:
AB = -3
BC = 2/3
AC = -1/4
Step-by-step explanation:
The slope is denoted by m and is calculated using the formula
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
The given vertices are:
A(-2,4) B(-1,1) C(2,3)
The sides will be:
AB, BC, AC
Let m1 be the slope of AB
Let m2 be the slope of BC
Let m3 be the slope of AC
Now
[tex]Slope\ of\ AB = m_1 = \frac{1-4}{-1+2} = \frac{-3}{1} = -3\\Slope\ of\ BC = m_2 = \frac{3-1}{2+1} = \frac{2}{3}\\Slope\ of\ AC = m_2 = \frac{3-4}{2+2} = \frac{-1}{4} = -\frac{1}{4}[/tex]
Hence,
The slopes of three sides of triangle are as follows:
AB = -3
BC = 2/3
AC = -1/4

If two angles are supplementary, the sum of the angles is 180°.
A complementary angle is one-half the measure of a supplementary angle.
A supplementary angle is twice the measure of a complementary angle.
Answer:
Which statements can be used to justify the fact that two right angles are supplementary? Select two options.
* A right angle measures 90°.
If two angles are complementary, the sum of the angles is 90°.
* If two angles are supplementary, the sum of the angles is 180°.
A complementary angle is one-half the measure of a supplementary angle.
A supplementary angle is twice the measure of a complementary angle.
Step-by-step explanation:
(A) and (C)
A right angle measures 90°, hence the sum of two right angles is 180° (supplementary)
AnglesAn angle is formed when two lines intersect each other. Two angles are said to be supplementary if their measures add up to 180 degrees while Two angles are called complementary if their measures add up to 90 degrees.
To justify the fact that two right angles are supplementary. Firstly a right angle measures 90°, hence the sum of two right angles is 180° (supplementary)

Answer:
Step-by-step explanation:
These types of problems can be solved with substitution.
We just have to translate the word problem into math.
#1:
F = family, I = individual
[tex]F + I = 188\\95F + 42I = 12,507[/tex]
[tex]F = 188-I\\95(188-I) + 42I = 12507\\17860 - 95I + 42I = 12507\\-53I = -5353\\I = 101\\\\F + I = 188\\F + 101 = 188\\F = 87[/tex]
87 Families, 101 individuals
#2:
The perimeter is 899 meters. The perimeter can be defined as:
[tex]2L + 2W = P\\2L + 2W = 899[/tex]
We are also given that
[tex]2L = W - 100\\so\\2L + 2W = 899\\W- 100 + 2W = 899\\3W = 999\\W = 333\\\\L = \frac{W-100}{2} = \frac{333-100}{2} = \frac{233}{2}[/tex]
W = 333 meters, L = 233/2 meters

A landscape architect is designing a rectangular flowerbed to be border with 28 Plants that are placed 1 m apart. He needs an inner rectangular space in the center for plants that must be 1 m From the border of the bed and that require 24 square meter for planting. What should the overall dimensions of the flowerbed be?
Answer:
length = 8m and width = 6m
Step-by-step explanation:
We are told that 28 Plants that are placed 1 m apart. This means that total perimeter of rectangular space = 28
Thus;
2L + 2W = 28
Divide both sides by 2 to get;
L + W = 14 - - - (eq 1)
Where;
L is length
W is width
Furthermore, we are told that he needs an inner rectangular space in the center for plants that must be 1 m From the border of the bed and that require 24 square meter for planting.
This means that;
(L - 2) × (W - 2) = 24
(L - 2)(W - 2) = 24
Divide both sides by (W - 2) to get;
L - 2 = 24/(W - 2)
From eq(1),we can say that;
L = 14 - W
Thus;
14 - W - 2 = 24/(W - 2)
(12 - W) = 24/(W - 2)
Multiply both sides by (W - 2) to get;
(12 - W)(W - 2) = 24
12W - W² + 2W - 24 = 24
W² - 14W + 48 = 0
From quadratic formula, we have;
[-(-14) ± √(-14)² - 4(1 × 48)]/(2 × 1)
This gives;
W = 8 or 6
From earlier, we saw that L = 14 - W
Thus, L = 14 - 6 = 8 or L = 14 - 8 = 6
Since values of W and L are similar, we will choose the higher value to be the length and the smaller value to be the width.
Thus, length = 8m and width = 6m

If f(x)= 5x-8 which of the following is the inverse of f(x)?
A. F^1(x) = x-5/8
B. F^1(x) =x-8/5
C. F^1(x) = x+8/5
D. F^1(x)= x+5/8
Answer:
c
Step-by-step explanation:
For an inverse function you take f(x) and turn that to y then you switch x and y. So you should start off with y= 5x -8. so then you switch x and y so x= 5y - 8. So then you solve. You subtract 8 from both sides and divide by 5 and you get F(x) inverse = x + 8/5

If sin t = -8/17 and t is a quadrant III angle, find cot t
Answer:cot t = 1.875
[tex]sin t=\frac{-8}{17}[/tex] but sin²t + cos²t = 1 ⇔ cos²t = 1 - sin²t
⇔cos t = [tex]\sqrt{1-sin^{2}t }=\sqrt{1-(\frac{-8}{17})^{2} }=|\frac{15}{17}|[/tex]
but t is a quadrant III angle => cos t = [tex]\frac{-15}{17}[/tex]
=> cot t = [tex]\frac{-15}{17}:\frac{-8}{17}=\frac{15}{8}=1.875[/tex]

A cow is eating green grass that grows in a field.
Which type of organism is the grass in this scenario
consumer
decomposer
prey
producer
A cow is eating green grass that grows in a field. The grass in this scenario is the producer.
'This is a basic food chain. The grass is a living organism that utilizes energy from the sun to make its own food through an interaction called photosynthesis. Then, different creatures eat the grass; it is their wellspring of energy.
Every living organism (plants and creatures) should eat food for the endurance of some sort or another. Plants make their own food through an interaction called photosynthesis. Using the energy from the sun, water, and carbon dioxide from the air and nutrients, they artificially make their own food. Since they make or produce their own food they are called makers.
Organisms that don't make their own food should eat either plants or creatures. They are called buyers. A few creatures get their energy from eating plants while different creatures get energy in a roundabout way from plants by eating different creatures that previously ate the plants.
Creatures that eat just plants are called herbivores. Creatures that eat the two plants and other creatures are called omnivores. Creatures that eat just different creatures are called carnivores.
A few creatures eat just dead or decaying materials and are called decomposers.

What is the formula for area of a parallelogram?
Use x for multiplication and / for division is necessary.
Answer:
The area of a polygon is the number of square units inside the polygon. Area is 2-dimensional like a carpet or an area rug.
Step-by-step explanation:
A parallelogram is a 4-sided shape formed by two pairs of parallel lines. Opposite sides are equal in length and opposite angles are equal in measure. To find the area of a parallelogram, multiply the base by the height. The formula is:
A = B * H where B is the base, H is the height, and * means multiply.
The base and height of a parallelogram must be perpendicular. However, the lateral sides of a parallelogram are not perpendicular to the base. Thus, a dotted line is drawn to represent the height. Let's look at some examples involving the area of a parallelogram.
