Answer:
15 minutes
Step-by-step explanation:
We can let t represent the time in hours that Kara ran today. Then her distance today is ...
distance = speed · time
distance = 6t
Her total distance for both days is ...
5 + 6t = 6.5
6t = 1.5 . . . . . . . . . . subtract 5
t = 1.5/6 = 1/4 . . . . . divide by 6
Kara ran 1/4 hour today. That is 15 minutes.

5(y+2/5)=-13
what is y
Answer:
y=11/5
Step-by-step explanation:
first divide by 5 on both sides
y+2/5=-13/5
subtract 2/5 on both sides to isolate the y
y=11/5
:))
Answer:
y=-3
Step-by-step explanation:
5(y+2/5) = -13
5y+2 = -13
subtract 2 from each side
5y+2-2 = -13-2
5y = -15
divide each side by 5
5y/5 = -15/5
y=-3
check:
5(y+2/5) = -13
substitute -3 for y
5(-3)+2/5) = -13
-15+2= -13
-13 = -13

A shoe sales associate earned $300 in November. In December she earned 8% more than she did in November. How much she earn in December? *
Answer:
$324.00
Step-by-step explanation:
Increase the number by 8% of its value.
Percentage increase = 8% × 300
New value =
300 + Percentage increase =
300 + (8% × 300) =
300 + 8% × 300 =
(1 + 8%) × 300 =
(100% + 8%) × 300 =
108% × 300 =
108 ÷ 100 × 300 =
108 × 300 ÷ 100 =
32,400 ÷ 100 =
324
$24.. 8% of $300 equals 24 so the associate made $324 dollars in December. 24+300=324

Answer:
3
Step-by-step explanation:
Multiply the dividend fraction numerator with the divisor fraction denominator to get the numerator
Multiply the dividend fraction denominator with the divisor fraction numerator to get the denominator = 36/12
Reduce the fraction by finding the greatest common factor. The greatest common factor of 36 and 12 is 12
Divide the numerator and denominator by the greatest common factor (12)
= 3/1
Convert to a mixed fraction by finding the whole number and remainder
= 3
Answer:
3
Step-by-step explanation:
Factor the numerator and denominator and cancel the common factors.
It will give you 3.

Which of the following statements is TRUE regarding b(x)?
A. Over the interval [0, 1], b(x) is negative and is increasing.
B. Over the interval [0, 1], b(x) is positive and is decreasing.
c. Over the interval [0, 1], 5(x) is positive and is increasing.
D. Over the interval [0, 1], b(x) is negative and is decreasing.
The only statement that is true regarding the given graph of polynomial b(x) is; Option D; Over the interval [0, 1], b(x) is negative and is decreasing.
The given graph represents the polynomial b(x). Let us look at the options;
Option A; Over the interval (0, 1), we can see that the curve is decreasing from b(x) = 0 to b(x) = -2. Thus, the statement is wrong.
Option B; Over the interval of (0, 1), b(x) is not positive over the interval (0, 1) and so the statement is wrong.
Option C; Over the interval of (0, 1), b(x) is not positive and increasing and so the statement is wrong.
Option D; Over the interval of (0, 1), b(x) is negative and is also decreasing and so this option is correct.

Sum of Angles: 180(n - 2)°Step-by-step explanation:
Step 1: Define
We are given a 8 sided polygon (a octagon)
n = 8
Step 2: Find Sum
Substitute in n [Sum of Angles]: 180(8 - 2)°(Parenthesis) Subtract: 180(6)°Multiply: 1080°Work out 23% of 42.
Give your answer correct to 1 decimal place.
The value of 23 % of 42 is 9.7
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number be A = 42
Now , let the percentage of the number A = 23 %
And , the equation will be
The 23 % of the number be = y
So , y = 23 % of 42
And , the equation is
y = ( 23 / 100 ) x 42
y = 0.23 x 42
On simplifying the equation , we get
y = 9.66
y ≈ 9.7
Therefore, the value of y is 9.7
Hence , The value of 23 % of 42 is 9.7

Which graph shows a proportional relationship?
There is a linear relationship between the variables x and y. And the line that passes through the origin. Then the correct option is C.
What are ratios and proportions?A ratio is an ordered set of integers a and b expressed as a/b, with b never equaling 0. A proportional is a mathematical expression in which two things are equal.
Let the two variables x and y.
Where x is an independent variable and y is the dependent variable that depends on x directly. Then we have
The variable y is directly proportional to the variable x.
y ∝ x
When the proportionality sign is removed a constant k comes into the equation. That is given as
y = kx
There is a linear relationship between the variables x and y.
And the line that passes through the origin.
