It is hard to explain but for step one you need to take the dotted line and the shape above hat and move it underneath the other shape to make a perfect rectangle.Step two since the dotted line is our new bottom. It has a length of 7. In this step we multiply 3 times 7 Step 3 this is the final step in which 3 times 7 equals 21.Hope this helped :)Use the divisibility tests to determine whether 900 is divisible by 2, 3, 5, 6, and 10

3 ratios that are equivalent to 3/8
Answer:
30/80 9/24 6/16
Step-by-step explanation:
Answer:
just multiply a fraction equal to 1 for example 2/2
3/8 x 2/2 = 6/16
3/8 x 3/3 = 9/24
3/8 x 4/4 = 12/32
it is equivalent because 2/2 is equal to 1 so it is being multiplied by 1

79.99 - 12% + 8%
please dhow your work
thank you
And be safe
Answer:
79.95
Step-by-step explanation:
The first step is to rewrite the percentages into decimals so they can be added or subtracted easier. To turn a percentage into a decimal, remove the percent sign and move the decimal two spaces to the left (in other words, divide the number by 100).
12% becomes -0.12
8% becomes 0.08
Now, let's solve.
79.99 - 0.12 + 0.08
Evaluating 79.99 - 0.12, the equation becomes 79.87 + 0.08.
Evaluating 79.87 + 0.08, we get the final answer, 79.95.

Sylvie is planning to visit her mother who lives 387 miles away. If
the price of gas ranges from $1.95 to $2.13 per gallon and Sylvie's
car gets 25 miles per gallon, about how much should she plan to
spend on gas for the trip there?
more than $50
$30 to $40
less than $30
$40 to $50
Answer:
$30 to $40
Step-by-step explanation:
387/25= 15.48 (this is how big the tank is)
15.48*2.13= 32.97 (about 33 paying for the highest price)
Sylvie will need approximately 15.48 gallons of gas for her 387-mile trip. With gas prices ranging from $1.95 to $2.13 per gallon, she should plan to spend between $30.20 and $32.96. Therefore, the anticipated cost falls between $30 and $40 that is option B is correct.
To calculate the cost of gas for the trip, we need to follow these steps:
Determine the number of gallons of gas needed for the trip:
Number of Gallons = Total Miles / Miles per Gallon
Number of Gallons = 387 miles / 25 miles per gallon = 15.48 gallons
Calculate the minimum and maximum cost of gas:
Minimum Cost = Number of Gallons * Minimum Price per Gallon
Minimum Cost = 15.48 gallons * $1.95 per gallon ≈ $30.20
Maximum Cost = Number of Gallons * Maximum Price per Gallon
Maximum Cost = 15.48 gallons * $2.13 per gallon ≈ $32.96
Both calculations indicate the cost will fall between $30 and $40. Therefore, the correct answer is: $30 to $40.

An actor invests some money at 5% simple interest, and $23,000 more than 3 times the amount at 6% simple interest. The total annual interest earned from the investment is $28,290. How much did he invest at each amount? Use the 6 step method.
Answer:
He invested $117,000 at 5% interests and 3*117,000 + 23000 = $374,000 at 6% interests
Step-by-step explanation:
Let's call x to the some money at 5% simple interest the actor invest. Then, he invested 3x + 23000 dollars at 6% simple interest.
At 5% simple interest, after one year he earned the following interests:
I = P*r*t
I = x*0.05
At 6% simple interest, after one year he earned the following interests:
I = (3x + 23000)*0.06 = 0.18x + 1380
The total annual interest earned from the investment is $28,290, then:
0.05x + 0.18x + 1380 = 28290
x = (28290 - 1380)/0.23
x = $117,000

Group of answer choices
(0, 6)
(0, 4)
(-4, 4)
(4, 4)
Answer:
(4,4)
Step-by-step explanation:
Answer:
(4,4). You already know the y value is 4, so you just plug that into the second equation. You'd get 3x-8=4, then 3x=12, then x=4. (x,y)=(4,4)
Express 8^1/2 in simplest radical form.
Final answer:
To express [tex]8^{1/2[/tex]in simplest radical form, recognize that it's equivalent to the square root of 8, then simplify to 2√2 by breaking down 8 into prime factors and finding pairs of factors.
Explanation:
To express [tex]8^{1/2[/tex] in simplest radical form, we follow these steps:
Recognize that an exponent of 1/2 is equivalent to the square root.
Find the square root of 8, which can also be written as √8.
Since 8 is not a perfect square, we can simplify it by breaking it down into its prime factors: 8 = 2 x 2 x 2.
Group the factors into pairs to determine the square root: 8 has one pair of 2s.
This pair comes out of the radical as a single 2, leaving one 2 inside the radical: 2√2.
Therefore, 8^1/2 simplifies to 2√2, which is the simplest radical form.

A scaled drawing uses a scale factor of 1:25. Is the drawing a reduction or an enlargement? Support your conclusion with an example.
Answer:
Reduction scale
Step-by-step explanation:
Enlarging scale means that the drawing is larger than the actual object. Hence the representative fraction will be greater than unity. For reducing scale the representative fraction is less than unity.
So now looking at 1:25, we see it's a reduction scaling because it's fraction is less than unity.
And what 1:25 means is that 1 on paper while the actual size of the object is 25

The correct sequence of transformations that maps rectangle ABCD onto rectangle A'B'C'D' is:
c. a dilation by a scale factor of 1/2
Here's why:
1. A dilation by a scale factor of 1/2 reduces the size of the original rectangle by half. This transformation scales down all the coordinates by a factor of 1/2. Given the coordinates of ABCD and A'B'C'D', this is the only transformation needed to achieve similarity.

The diameter of the circle is 18 m Eugene incorrectly says that the circumference of the circle is about 113.04 m what is the circumference of the circle? What mistake did Eugene make? Use 3.14 for pie
Hi
formula. for circumference of a circle is. : 2πR. if you have the radius.
As the diameter is twice the radius, then circumference is. diameter π
then : 18*π≈ 56.52
the mistake was to take the diameter as the radius.
Final answer:
The circumference of the circle is 56.52 m. Eugene made the mistake of using the radius instead of the diameter to calculate the circumference.
Explanation:
The circumference of a circle can be found using the formula C = πd, where C represents the circumference and d represents the diameter.
In this case, the diameter of the circle is given as 18 m. If we substitute this value into the formula, we get:
C = 3.14 * 18 = 56.52 m
Eugene's mistake was that he used the value of the radius instead of the diameter to calculate the circumference. The correct circumference is 56.52 m, not 113.04 m.

Joseph is ordering a taxi from an online taxi service. The taxi charges $4 just for the
pickup and then an additional $1 per mile driven. How much would a taxi ride code if
Joseph is riding for 9 miles? How much would a taxi ride cost that is m miles long?
Answer: $13 for the 9 mile ride.
The taxi ride that is m miles long would cost as follows: 4 + m
Step-by-step explanation:
The cost of Joseph's taxi ride is calculated by adding a flat fee of $4 to $1 for each mile driven. Thus, a 9-mile ride would cost $13. For a ride of m miles, the cost would be $4 plus $1 per mile.
Explanation:The cost of a taxi ride can be determined using a function that considers two components: a flat fee, and a rate per mile. In Joseph's case, the online tax service charges a $4 flat fee for pickup, and $1 per each mile driven. Hence, the equation for the cost of a taxi ride (C) for Joseph is as follows: C= 4+1*m.
For a ride of 9 miles, we would substitute m with 9: C = 4+ 1*9, which simplifies to C = $13. Therefore, a 9-mile ride would cost $13.
For a taxi ride that is m miles long, the cost would be C = 4 + 1*m. The 4 represents the flat fee, and the 1*m represents the cost per mile that is driven multiplied by the number of miles in the ride. Therefore, a taxi ride that is m miles long would cost $4 plus $1 per mile.

Find the unit rate.
150 mi on 10 gal of gas
A: 15 mi per gal
B: 10 mi per gal
C: 150 mi per gal
The unit rate of miles per gallon is found by dividing the total miles (150 mi) by the total gallons (10 gal), resulting in a unit rate of A) 15 miles per gallon.
To find the unit rate of miles per gallon when given 150 miles on 10 gallons of gas, we divide the total number of miles driven by the number of gallons of gas used. The calculation is as follows:
Write down the given values: 150 miles (mi) and 10 gallons (gal).
Divide the total miles by the total gallons to find the unit rate: 150 mi ÷ 10 gal = 15 mi/gal.
Therefore, the unit rate is 15 miles per gallon, which is option A: 15 mi per gal.
