Answer:
Step-by-step explanation:
The thing you have to realize is that the diagonals of a parallelogram bisect each other. So DF = BF. With that fact, you get
4y + 19 = 10y - 11 Add 11 to both sides
4y+19+11 = 10y-11+11 Combine
4y + 30 = 10y Subtract 4y
4y-4y +30 = 10y - 4y Combine
30 = 6y Divide by 6
y = 30/6
y = 5

Two planes travel at a constant speed which plane a travels 2000 and 800 miles in five hours Plan B travels 3885 miles in seven hours which plane is faster
Answers
Answer:
Since its speed is higher, plane 1 is faster than plane 2.
Step-by-step explanation:
Comparing Speeds
The formula for the speed of an object who travels a distance d in a time t is:
[tex]\displaystyle v=\frac{d}{t}[/tex]
We have to compare the speeds of the two planes:
The first plane travels d1=2800 miles in t1=5 hours
The second plane travels d2=3885 miles in t2= 7 hours
Calculate both speeds as follows:
[tex]\displaystyle v_1=\frac{d_1}{t_1}[/tex]
[tex]\displaystyle v_1=\frac{2800}{5}[/tex]
[tex]v_1=560\ mi/h[/tex]
[tex]\displaystyle v_2=\frac{d_2}{t_2}[/tex]
[tex]\displaystyle v_2=\frac{3885}{7}[/tex]
[tex]v_2=555\ mi/h[/tex]
Since its speed is higher, plane 1 is faster than plane 2.
Susan makes a purchase of $175 and is charged 7.75% for sales tax. What is the total cost of the purchase if Susan charges it on a credit card with a daily interest rate of 0.039% and pays the balance off at the end of 30 days? a. $176.17 b. $186.70 c. $190.77 d. $200.26
Answers
Answer:
C. 190.77
Step-by-step explanation: edge 2022
The required, total cost of the purchase is $190.77. Option C is correct.
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 total cost of the purchase, we first need to calculate the amount of sales tax and add it to the original price.
Sales tax = 7.75% of $175 = 0.0775 x $175 = $13.56
Total cost of purchase = $175 + $13.56 = $188.56
If Susan charges the purchase to her credit card and pays it off after 30 days, she will be charged interest on the outstanding balance for those 30 days. The interest rate is 0.039% per day, which is equivalent to 1.17% per month (0.039% x 30).
The interest charged on the outstanding balance after 30 days will be:
Interest = $188.56 x 1.17% = $2.20
Therefore, the total cost of the purchase, including sales tax and credit card interest, will be,
Total cost = $188.56 + $2.20 = $190.76
Therefore, the total cost of the purchase is $190.77.

Explanation:
Jack has $65 to spend on art supplies. He needs to buy an easel that costs $18. He also wants to buy some canvases that cost $11 each
Which of the following inequalities represents the amount of money Jack can spend if he buys n canvases?
A:65 >(line underneath sign)18 + 11n
B:65 > 18 + 11n
С:65 < (line underneath sign) 18 + 11n
D:65 < 18 + 11n
Answers
Answer:
C
Step-by-step explanation:
Jack can spend less than or equal to. So C is correct.
The inequality represents the given situation is 65 ≥ 18 + 11n will be correct thus, option (A) is correct.
What is inequality?A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.
In essence, a comparison of any two values reveals whether one is less than, larger than, or equal to the value on the opposite side of the equation.
As per the given,
Total budget = 65
Total spent = 18 + 11n where n is the number of canvases.
Total spent ≤ total budget
18 + 11n ≤ 65
Hence "The inequality represents the given situation is 65 ≥ 18 + 11n will be correct".

What is the length and width of the rectangle? \text{Width} =Width=start text, W, i, d, t, h, end text, equals
Answers
Answer:
This means that the width = 3y²
The length = 4y+7y³
Step-by-step explanation:
Given
Area of the rectangle = 12y^2+21y^5
Width of the rectangle is the greatest common monomial of 12y^2 and 21y^5
First let us get the greatest common monomial of 12y^2 and 1^5
12y^2 = (3 * y * y) * 4
21y^5 = (3 * y*y)*y*y*y* 7
Hence the greatest common monomial is 3 * y * y = 3y²
Factor out 3y² from the area function;
12y^2+21y^5
3y² (4y+7y³) = Area of the rectangle
Length * Width = 3y² (4y+7y³)
On comparing both sides of the equation
This means that the width = 3y²
The length = 4y+7y³

Answer:
36,42,102
Step-by-step explanation:
A triangle is 180° total so your equation to find x is:
3x+6+4x+2+10x+2=180°
17x+10=180
17x=170
x=10
to find the individual sides:
3(10)+6=36
4(10)+2=42
10(10)+2=102
to make sure this is right, add 36+42+102. It should equal 180 and it does
