Answer:

A) Bobby's overall grade is 70.4%

Step-by-step explanation:

To solve this problem we must calculate the percentages each grade represents from the overall grade. Therefore:

assignment = 85*30% = 85*30/100 = 25.5%

tests = 72*20% = 72*20/100 = 14.4%

exam = 61*50% = 61*50/100 = 30.5%

total = assignment + tests  + exam

total = 25.5 + 14.4 + 30.5 = 70.4

Bobby's overall grade is 70.4%. Therefore the correct answer is A).

Answer:

23.5

Step-by-step explanation:

First the shaded area is 28 but there is a triangle so we have to solve the area of the triangle. (formula for triangle: B x H x 1/2) 3 times 3=9 divided by 2=4.5

28-4.5=23.5

What is an equation of the line that passes through the point (−2,−3) and is parallel to the line 4x-y=14
liraira [26]

Answer:

4x - y = -5

Step-by-step explanation:

The equation of a new line which is parallel to old line 4x - y = 14 looks exactly the same as that of the old line EXCEPT that we replace the constant, 14, with C and find C for the line that passes through (-2, -3).

4x - y = 14     becomes     4x - y =  C

Now substitutte -2 for x, -3 for y and calculate C:

4(-2) - (-3) = C, or

-8 + 3 = C = - 5

Thus, the new equation is 4x - y = -5

Which equation is equivalent to log^x36=2?
Dennis_Churaev [7]

The equation which is equivalent to \log _{x} 36=2 is x^{2}=36 or x = 6 (\log _{6} 36=2).

<u>Step-by-step explanation:</u>

Given Equation:

           \log _{x} 36=2

As we know, in terms of logarithmic rules, when b is raised to the power of y is equal x:

           b^{y}=a

Then, the base b logarithm of x is equal to y

           \log _{b}(x)=y

Now, use the logarithmic rule for the given equation by comparing with above equation. We get b = x, y = 2, and x = 36. Apply this in equation,

            b^{y}=a

            x^{2}=36

When taking out the squares on both sides, we get x = 6. Hence, the given equation can be written as \log _{6} 36=2
