Answer:
60 km/h
Step-by-step explanation:
Average speed is total distance over total time.
Total distance: 30 + 0 + 150 = 180 km.
Total time: 0.75 + 0.25 + 2 = 3 hrs.
180/3 = 60/1

Step-by-step explanation:
Hey there!
According to the figure;
9v = 31° + 4v + 44° { The exterior angle is equal to the sum of opposite adjacent interior angles}
9v-4v = 44°+31°
5v = 75°
v = 75°/5
Therefore, v= 15°.

Shel bought a $6,000 desk based on her income she can only afford to pay 600 per month The charge on the unpaid balance is 2% each month Calculate the balance outstanding at the end of month 2
Answer:
$5,030.40
Step-by-step explanation:
The balance outstanding at the end of any month is the due amount after adjusting for interest and loan repayment amount. The amount outstanding can be calculated as:
First month
Due amount = $6,000
Interest at 2% = $6,000*2% = $120
Loan repayment = $600
Reduction in balance = $600 - $120 = $480
Balance remaining = $6,000 - $480 = $5,520
Second month
Due amount = $5,520
Interest at 2% = $5,520*2% = $110.4
Loan repayment = $600
Reduction in balance = $600 - $110.4 = $489.60
Balance remaining = $5,520 - $489.60 = $5030.40
Hence, the balance outstanding at the end of month 2 is $5,030.40
Hannah works at an electronics store as a salesperson. Hannah earns a 7% commission on the total dollar amount of all phone sales she makes, and earns a 7% commission on all computer sales.
How much money would Hannah earn in
commission on a day that she sold $1000 worth of phones and $1700 worth of computers?
How much money would Hannah earn in commission on a day that she
sold $p worth of phones and $c worth of computers?
Answer:
Step-by-step explanation:1000x.07 70
1700x.07. 119
119+70. 189
The amount of commission earned on a day that she sold $1000 worth of phones and $1700 worth of computers is $189.
The amount Hannah earns in commission on a day that she
sold $p worth of phones and $c worth of computers is 0.07 ( p + c).
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Commission on phones = 7%
Commission on computers = 7%
Now,
Sold phones worth = $1000
Computer sold worth = $1700
Now,
The total commission earned.
= 7/100 x 1000 + 7/100 x 1700
= 70 + 119
= $189
Now,
The total commission earned.
= 7/100 x p + 7/100 x c
= 7/100(p + c)
= 0.07 (p + c)
Thus,
$189 commission was earned.
0.07 ( p + c) commission was earned.

Solve for x
Is it A,B,C or D?
Answer:
A makes the most sense, you would get rid of Y by multiplying it,it is the opposite of divison, this is because x is already almost by itself. the last step would be to get rid of Y. you would multiply Y to cancel it out on the right side and do the same to the left. this automatically gets rid of B and C,leaving A and D, but D doesnt have the R,so that gets rid of D, leaving A.
the sum of two numbers is 72 the greater number is 8 more than the smaller number which equation can be used to solve for the smaller number?
a x - (x + 8) = 72
b x + (x + 8) =72
c x(x + 8) = 72
d x(x - 8) = 72
Answer:
let x is the smaller number
bigger number is x + 8
The sum of two numbers is 72
so
x + (x+8) = 72
answer
x + (x + 8) = 72
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Two numbers add up to 72
let's assume they r x and y
ome number is 8 more than the other
so it will be x and x+8
Therefore x+x+8=72

Write as a monomial in standard form:
(–x^2y^3m)^5
Answer: -x^10y^15m^5
Explanation:
The term -x^2 is the same as -1*x^2
Raising -1 to an odd number power leads to -1. So this is why the answer has the negative out front.
For each of the variable terms, multiply the inner and outer exponents. For example, (x^2)^5 = x^(2*5) = x^10.
The general rule is (a^b)^c = a^(b*c).
For the term 'm', think of it as m^1
The sum of two number is 18. 5 times the first number subtracted from 4/7bof the second number is 14. Find the number
Answer:
The numbers are [tex]-\frac{2}{3}[/tex] and [tex]18\frac{2}{3}[/tex]
Step-by-step explanation:
Let x and y be the numbers
According to the statement, "The sum of two number is 18.", first equation will be:
[tex]x+y = 18\ \ \ \ Eqn\ 1[/tex]
And according to "The sum of two number is 18. 5 times the first number subtracted from 4/7bof the second number is 14." Second equation will be:
[tex]\frac{4}{7}y-5x = 14[/tex]
Multiplying whole equation by 7
[tex]7*\frac{4}{7}y-7*5x = 7*14\\4y-35x=98\\-35x+4y = 98\ \ \ \ Eqn\ 2[/tex]
From equation 1
[tex]x+y = 18\\y = 18-x[/tex]
Putting this in second equation
[tex]-35x+4(18-x) = 98\\-35x+72-4x= 98\\-39x = 98-72\\-39x = 26\\\frac{-39x}{-39} = \frac{26}{-39}\\x = -\frac{2}{3}[/tex]
Putting x = -2/3 in equation 1
[tex]-\frac{2}{3}+y = 18\\y = 18+\frac{2}{3}\\y = 18\frac{2}{3}[/tex]
Hence, the numbers are [tex]-\frac{2}{3}[/tex] and [tex]18\frac{2}{3}[/tex]

The missing points are (7, 11), and (9, 9.8) and the type of correlation is negative.
What is the line of best fit?A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
[tex]\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2}\\\\\\\rm c = \dfrac{\sum y -m \sum x}{n}[/tex]
Let the line of best fit is:
y = mx + c
The missing points are:
(7, 11), and (9, 9.8)
The correlation will be negative.
The line of best fit is shown in the picture.
Thus, the missing points are (7, 11), and (9, 9.8) and the type of correlation is negative.
