Answer:
39 cm
Step-by-step explanation:
Given
ΔABC and ΔA'B'C'
B = 5 cm
B' = 15 cm
Perimeter ΔABC = 13 cm
Required
Determine the perimeter of ΔA'B'C
[Since ΔABC is dilated to give ΔA'B'C', the first step is to get the scale factor.]
Scale Factor = ΔA'B'C ÷ ΔABC
[Using side B and B' as points of reference]
Scale Factor = B' ÷ B
[Substitute values for B' and B]
Scale Factor = 15 ÷ 5
Scale Factor = 3
[The perimeter of ΔA'B'C' is then calculated as:]
Perimeter ΔA'B'C'= Scale Factor * Perimeter of ΔABC
ΔA'B'C = 3 * 13 cm
ΔA'B'C = 39 cm

write the tangent ratios for angle p and angle q, reduce if needed
Answer:
tanP = [tex]\frac{20}{21}[/tex] , tanQ = [tex]\frac{21}{20}[/tex]
Step-by-step explanation:
tanP = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{QR}{PR}[/tex] = [tex]\frac{20}{21}[/tex]
tanQ = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{PR}{QR}[/tex] = [tex]\frac{21}{20}[/tex]
Divide x3 + x2 - X+ 2 by r+ 4 using long division.
Answer:
6-x+2bry
Step-by-step explanation:
Answer:
Here are the steps required for Dividing by a Polynomial Containing More Than One Term (Long Division):
Step 1: Make sure the polynomial is written in descending order. If any terms are missing, use a zero to fill in the missing term (this will help with the spacing).
Step 2: Divide the term with the highest power inside the division symbol by the term with the highest power outside the division symbol.
Step 3: Multiply (or distribute) the answer obtained in the previous step by the polynomial in front of the division symbol.
Step 4: Subtract and bring down the next term.
Step 5: Repeat Steps 2, 3, and 4 until there are no more terms to bring down.
Step 6: Write the final answer. The term remaining after the last subtract step is the remainder and must be written as a fraction in the final answer.

What is the answer to 5 divided by 2/7
Answer:
17 1/2
Step-by-step explanation:
To divide a whole number and a fraction, write the whole number as a fraction (in this case, 5 becomes 5/1). Then, change the division symbol to a multiplication symbol. After that, you flip the second number and multiply. As you can see, you get 35/2 as the answer. To simplify that, divide 35 by 2. The answer becomes the whole number, the divisor becomes the denominator, and the remainder becomes the numerator. That means our simplified answer is 17 1/2.

Answer:70 minutes
Step-by-step explanation:this is because since 1 min =6 cartons .And u are figuring out for 420 cartons ,you think what is 420 divide 6 which is 70 .So it means 70.
1 min = 6 cartons
x min = 420 cartons
do 420 times 1 it gives u 420 then divide by 6.

round 5,816 to the nearest hundred
Answer:
5800
Step-by-step explanation:
that is to the nearest hundred
Answer:
5,800
Step-by-step explanation:
In 5,816. the number in the hundred place is the 8. The rule in rounding is 5 and above goes up, under 5 stay the same. The number after the 8 is the 1 and 1 is less than 5, so stays the same. So the 5,816 rounded to the hundred place is 5,800.

Step 1: Define
3x - y = 18
y = 27
Step 2: Solve for x
Substitute in y: 3x - 27 = 18Isolate x term: 3x = 45Isolate x: x = 15Answer:
15
Step-by-step explanation:
3x - y = 18
Insert the value of y in the equation.
3x - 27 = 18
Shift -27 to the other side of the equation.
3x = 18 + 27
3x = 45
x = 45 ÷ 3
x = 15

Write an equation of the line with the given slope that contains the given point.
a) Q(5,2), slope -2
Answer:
[tex]y=-2x+12[/tex]
Step-by-step explanation:
We can use the point-slope form given by:
[tex]y-y_1=m(x-x_1)[/tex]
Where m is the slope and (x₁, y₁) is a point.
So, we will substitute -2 for m and (5, 2) for (x₁, y₁). This gives us:
[tex]y-(2)=-2(x-(5))[/tex]
Simplify:
[tex]y-2=-2(x-5)[/tex]
Distribute:
[tex]y-2=-2x+10[/tex]
Add 2 to both sides. Hence, our equation is:
[tex]y=-2x+12[/tex]

If i roll 2 dice what is the probability that neither of them are prime nor even?
Answer:
There are 3 prime numbers shown on the die: 2, 3 and 5. The probability of showing a prime number on a single die is 1/2, hence the probability of not showing a prime number is also 1/2. Total possible outcomes when two dice are rolled = 6*6 = 36. Total possible outcomes when two dice are rolled = 6*6 = 36.
please help. Will give brainliest!!
Answer:
A.

Based on the information presented what do think Manny should decide? Option #1: Keep the old car Option #2: Buy the fuel-efficient used car Option # Number
Answer:
Manny should keep the old car since he gets to spend less on it in three years compared to getting the fuel-efficient car.
Step-by-step explanation:
Step 1:
Number of miles Manny commutes per week = 160
Cost per gallon of gasoline. = $2.9
Mileage of old car = 20 miles per gallon
Maintenance cost per year of old car = $760
Cost of new car = $7000
Maintenance cost per month of new car = $10
Mileage of new car = 31 miles per gallon
Step 2:
There are 52 weeks in a year. Total distance Manny will commute in 3 years = 160 * 52 * 3 = 24960 miles
Maintenance cost of old car in 3 years = $760 * 3 = $2280
Maintenance cost of new car in 3 years = $10/month * 12 months * 3 = $360
Gasoline usage of old car in 3 years = 24960 miles/20 miles per gallon = 1248 gallons
Cost of gasoline = 1248 * $2.9 = $3619.2
Gasoline usage of new car in 3 years = 24960 miles/31 miles per gallon
Cost of gasoline = $2.9 * 24960 miles/31 miles per gallon = $2334.97 or approximately $2335
Step 3:
Total expenditure on old car for 3 years = $2280 + $3619.2 = $5899.2
Total expenditure on new car for 3 years = $7000 + $360 + $2335 = $9695
From the calculations above, Manny will spend $5899.2 on the old car compared to $9695 on the new car in three years.
Therefore, Manny should keep the old car since he gets to spend less on it in three years compared to getting the fuel-efficient car.

simplify:-5 1/4-(-7 1/2)
Answer:
D. 2 1/4.
Step-by-step explanation:
First, convert both -5 1/4 and -7 1/2 into improper fraction. These would be -21/4 and -15/2.
-21/4 - (-15/2)
Two negatives in a row make a positive.
-21/4 + 15/2
Double both the numerator and denominator of 15/2 to make it have the same denominator as -21/4. This would 30/4.
-21/4 + 30/4
Put -21 + 30 over 4 to make it a single fraction.
(-21 + 30)/4
Add -21 and 30 to get 9.
9/4
Convert 9/4 into a mixed number: 2 1/4
The answer to -5 1/4 - (-7 1/2) is 2 1/4, which is D.
