At the end of the summer, a store marks down all the outdoor furniture 20%. A family bought 4 chairs that originally cost $102. How much was the cost of the 4 chairs?
Answer:
$81.60
Step-by-step explanation:
A 20% markdown means that the chairs were sold at 80% of the original cost.
Original cost = $102
markdown = 20%
Cost after markdown = original cost* (1-markdown)
Cost after markdown = 102 *(1 - 0.20)
= 102*0.80
= 81.6
Therefore, the 4 chairs were sold at a total cost of $81.60
10. How can you use similar triangles to solve real-world problems?
Final answer:
Similar triangles can be used to solve real-world problems by applying the concept of proportionality. By comparing corresponding sides of similar triangles, you can find the unknown measurements.
Explanation:
Similar triangles can be used to solve real-world problems by applying the concept of proportionality. In a pair of similar triangles, corresponding sides are in proportion to each other. This means that if you know the measurements of one triangle, you can use the ratios of corresponding sides to find the measurements of the other triangle.
For example, if you have a 10-meter tall tree and its shadow is 5 meters long, and you want to determine the height of a nearby building using the shadow it casts, you can set up a proportion using the tree's height and shadow length as one ratio and the building's height and its shadow length as the other ratio. By solving this proportion, you can find the height of the building.
Similar triangles can be used to solve various real-world problems involving measurements such as distances, heights, widths, and more. By identifying corresponding sides and setting up ratios, you can find the unknown measurements.
Explain the effect of C on the graph of Y=f(x) for the function y=f(x+c)
f(x) + c -> up by c
f(x) - c -> down by c
f(x + c) -> left by c
f(x - c) -> right by c
For y = f(x + c), the y value of x now takes the y value of the function of x + c, or the one c to the right of x, shifting the entire graph left by c.
The function y=f(x+c) signifies a horizontal shift of the graph y=f(x). The graph shifts left if 'c' is positive and right if 'c' is negative.
Explanation:In mathematics, y=f(x+c) represents a transformation of the graph y=f(x). Specifically, the addition of the constant 'c' in the function results in a horizontal shift of the graph. If 'c' is positive, then the graph moves to the left by 'c' units. If 'c' is negative, then the graph moves to the right by 'c' units.
Let's look at an example to illustrate this. Consider the function y = f(x) where f(x) = x^2, the graph is a parabola centered on the origin (0,0). If we transform this function into y = f(x+c), where c = 2, the resulting graph y = (x+2)^2 would be a parabola shifted 2 units to the left of the origin.

Fred has $27 to buy sketch paper for his art class. Each sketch pad costs $2.
How many sketch pads can he buy? Do not include units in your answer.
Answer: 13
Step-by-step explanation:
13x2=26 and since you cant have a half sketch pad he can only have 13.
Fred can buy 13 sketch pads with his $27, as each pad costs $2 and after dividing $27 by $2, the result is 13.5, which rounds down to 13 because he cannot purchase half a sketch pad.
Explanation:Fred has $27 to buy sketch paper, and each sketch pad costs $2. To find out how many sketch pads he can buy, we divide the total amount of money Fred has by the cost of each sketch pad.
So, we calculate this by performing the division:
Number of sketch pads = Total money / Cost of each sketch pad
Number of sketch pads = $27 / $2 = 13.5
Since Fred cannot buy half a sketch pad, we'll round down to the nearest whole number, which means Fred can buy 13 sketch pads with the money he has.
An orchard has 651 orange trees. The number of rows exceeds the number of trees per row by 10. How many trees are there in a row
Answer:
The number of trees in each row is 21.
Step-by-step explanation:
Let us assume the number of trees in each row = m
So, the number of rows in the orchard = Number of trees in each row + 10
or, total number of trees in each row = (10 +m)
Now, Total number of Trees = Number of Rows x Number of trees in 1 row
⇒ 651 = m (m + 10)
[tex]651 = m^2 + 10m\\\implies m^2 + 10m - 651 =0\\or, m^2 + 31m 21m - 651 =0\\or, m(m +31) -21(m+31) =0\\\implies (m +31) (m-21) = 0[/tex]
⇒ (m +31) = 0, or (m-21) = 0
⇒ m= -31, or m = 21
Now, as m = The number of trees in each row, so m ≠ -31
So, m = 21
Hence, the number of trees in each row is m = 21.
From least to greates -4 3/7, -4 5/6, -5 3/7, 4 2/7, 5 1/7
Answer:
The least number is - 5 3/7.
Then in order we have - 4 5/6.
- 4 3/7
4 2/7
And the greatest is 5 1/7.
Step-by-step explanation:
1. Let's look for the least number of this set and then continue to order them until we find the greatest, this way:
The least number is - 5 3/7 because is the biggest negative number among the three given to us.
The second least number is - 4 5/6, that is < - 5 3/7 and > than - 4 3/7. Their whole number is the same but the fraction part is bigger: 5/6 > 3/7 or 0.83 > 0.42.
The third number is the only negative number remaining: - 4 3/7.
Now, the fourth term in order is 4 2/7, because it's < 5 1/7.
Finally, the greatest number of the set given to us is 5 1/7.

9y - 0.2xy is the answer after applying Distributive property.
Step-by-step explanation:
Given:
[tex]y(9-0.2x)[/tex]
To Find:
Expression after applying Distributive property.
Solution:
Distributive property:
In Distributive property, it lets you multiply a sum by multiplying each addend separately and then add the products.
OK, that definition is not really helpful for most people. It is easier to understand the meaning if you look at the examples below.
i.e A (B + C) = A×B + A×C
On Applying Distributive property to the given expression we get,
[tex]y(9-0.2x)=y\times 9-y\times0.2\times x\\y(9-0.2x)=9y-0.2\times x\times y[/tex]
[tex]\therefore y(9-0.2x)=9y-0.2xy \ \ \ \textrm{we can write xy or yx it same as 2*3 = 3*2 = 6}[/tex]
9y - 0.2xy
is the answer after applying Distributive property.
The expression y(9-0.2x) expands to 9y - 0.2xy using the distributive property, where y is multiplied by each term inside the parentheses.
Explanation:To expand the expression y(9-0.2x) using the distributive property, you multiply y by each term inside the parentheses. Applying the distributive property, we get:
y × 9 - y × 0.2x
Which simplifies to:
9y - 0.2xy

the equatorial circumference of Earth is 4.01 * 10^4 kilometers. One kilometer is equivalent to 3.94 x 10^4 inches. What is the Equatorial circumference of Earth in inches?
Answer: [tex]1,579,940,000\ inches[/tex]
Step-by-step explanation:
Let be "x" the Equatorial circumference of Earth in inches.
Based on the data given in the exercise, you know that the equatorial circumference of Earth is [tex]4.01 * 10^4\ kilometers[/tex].
You also know that:
[tex]1\ kilometer=3.94* 10^4\ inches.[/tex]
Then, you can set up the following proportion:
[tex]\frac{3.94*10^4\ inches}{1\ kilometer}=\frac{x}{4.01 * 10^4\ kilometers}[/tex]
Finally, you must solve for "x" in order to find its value.
Applying this procedure you get the following result:
[tex](4.01 * 10^4\ kilometers)(\frac{3.94*10^4\ inches}{1\ kilometer})=x\\\\x=1,579,940,000\ inches[/tex]
The equatorial circumference of Earth in inches is found by multiplying the given circumference in kilometers by the conversion from kilometers to inches.
Explanation:The equatorial circumference of Earth is stated to be [tex]4.01 \times 10^4[/tex] kilometers. We also have the conversion factor that 1 kilometer is equivalent to [tex]3.94 \times 10^4[/tex]inches. We can find the equatorial circumference of Earth in inches by multiplying the circumference in kilometers by the conversion factor.
So, the calculation becomes: [tex]4.01 \times 10^4 km \times 3.94 \times 10^4 inches/km.[/tex] The kilometers cancel out and the result will be in inches. This type of conversion is a common task in mathematics and physics where we often have to switch between units of measurement.

A. 0.7369 cm3 C. 73.69 cm3
B. 13.57 cm3 D. 1,357 cm3
Answer:
C
Step-by-step explanation:
D=m/v
Rearranging the formula
v=m/D
V=1000/13.56
V=73.69 cm3
Answer:
v = 73.69 cm²
Step-by-step explanation:
V = m/p
Where,
v is volume
m is mass
p is density
So,
v = 1000 / 13.57
v = 73.69 cm²
I believe that this maybe a wrong answer because 1000 kg is suppose to be converted to g but since the answer (which is 73692 cm³) would not meet any of the options, I would have to go for that answer.

Brianna hoped to get 100 pumpkins from her garden this year. Since the weather was favorable, 20% more pumpkins grew than she expected. Unfortunately, animals ate 30% of all the pumpkins that grew. How many pumpkins were left? Is the final number of pumpkins more than or less than she hoped?
Answer:
84 pumpkins; less than she expected
Step-by-step explanation:
Find 20% of 100 and add the percent to 100. That is 120.Then find 30% of 120, which is 36. Then do 100-36 to get 84 pumpkins. That is less than 100 so she got less than she hoped.
The final number of pumpkins less than she hoped is 84 pumpkins.
What is the percentage?A percentage is a number or ratio expressed as a fraction of 100.
A percentage is a dimensionless number, it has no unit of measurement.
Brianna hoped to get = 100 pumpkins
percentage of increased yield = 20%
∴ number of pumpkins = 100*20/100
= 20 pumpkins more.
total pumpkins yield = 100 + 20 = 120.
percentage of pumpkins animals eat = 30%
∴ number of pumpkins = 120*30/100
= 36 pumpkins more.
total number of pumpkins she left = 120 - 36

Can someone please help me? Thanks
Answer:
693 sq. m.
Step-by-step explanation:
The figure consists of a triangular prism (Bottom Part) and a Triangular Pyramid (Top Part). We will find the volume of each and add it up to get volume of total figure.
1. Volume of Triangular Prism = Area of Triangular Base * Height
Area of Triangular Base = (1/2)*base*height
Given that the triangle is a right triangle, we find the unknown side by using Pythagorean Theorem, which tells us:
Leg^2 + Another Leg^2 = Hypotenuse^2
8.8^2 + Another Leg^2 = 13.7^2
77.44+ Another Leg^2 = 187.69
Another Leg (unknown side, or the base of the triangle) = Sqrt(187.69-77.44) = 10.5 (this is base of triangle)
So, we have:
Area of Triangular Base = [tex]\frac{1}{2}*10.5*8.8=46.2[/tex]
Thus,
Volume of Triangular Prism = 46.2 * 10(given) = 462 sq.m.
2. Volume of Triangular Pyramid = (1/3) * area of triangular base * height
Here, area of triangular pyramid is 46.2 (already found)
the height of the pyramid is 25 - 10 = 15
SO, we have:
Volume of Triangular Pyramid = [tex]\frac{1}{3}*46.2*15=231[/tex] sq. m.
Now we sum them up and get total volume of the figure:
Total Volume of Figure = 462+ 231 = 693 sq. m.
