MATHEMATICS MIDDLE SCHOOL

Patricia scored 80% on a math test. She missed 4 problems. How many problems were on the test?

Answers

Answer 1
Answer:

Answer: There are 20 problems on the test.

Step-by-step explanation:

Since we have given that

Patricia scored 80% on a math test.

She missed 4 problems.

So, 20% of the math test is equal to 4 problems.

Let the total number of problems on the test be x

According to question,

(20)/(100)* x=4\n\nx=(100)/(20)* 4\n\nx=20

Hence, there are 20 problems on the test.
Answer 2
Answer: There would be exactly twenty problems on the test for her to be able to get 80%.
You know it can't be ten because then that would make it 60% not 80% but if you add the first number of the percentage (8) and multiply it by two it will get you 16 then if you add 4 to that that would make it 20 and 16/20 equals 80%

PLEASE HELP GIVING BRAINLIEST I NEED TO PASS THIS CLASS!!!The graph of an exponential function of the form y = f(x) = a^x passes through the points_____       and ____ . The graph lies ____ the x-axis.

Answers

y = f(x) = a^x is an expo function with constant base a and exponent x.  First, let's assume that a is positive and lying either in (0,1) or (1, infinity).

If a satisfies  0<a<1, then the expo fn is decreasing with x.  Its y-intercept is (0,1) because a^0 = 1 for all a that satisfy (0,1).  Same is true for (a>1). 

In both cases the horiz. asymptote is the line y=0.

y = f(x) = a^x has only one intercept, the y-intercept, (0,1).  

However, z = f(x) = a^x + C could have an x-intercept for certain C.  

Which is true about the degree of the sum and difference of the polynomials 3xy - 2xy4 - 7xy and -8xy + 2x°y4 + xy?O Both the sum and difference have a degree of 6.
O Both the sum and difference have a degree of 7.
The sum has a degree of 6, but the difference has a degree of 7.
The sum has a degree of 7, but the difference has a degree of 6.

Answers

The degree of the sum and difference of the polynomials are 6 and 7 respectively.

The degree of the sum and difference of the polynomials.

3x⁵y - 2x³y⁴ - 7xy³ and -8x⁵y + 2x³y⁴ + xy³

The degree of sum = monomial with the highest power = 5 + 1 = 6

The degree of difference = monomial with the highest power = 3 + 4 = 7

Therefore, the degree of the sum and difference of the polynomials are 6 and 7 respectively.

olivia is making scarves. each scarf will have 5 rectangles, and 2/5 of the rectangles will be purple. how many purple rectangles does she need for 3 scarves?

Answers

We have to find how many purple rectangles does Olivia need for 3 scarves. We know that each scarf will have 5 rectangles and 2/5 of the rectangles will be purple: 2/5 * 5 = 2. It means that each scarf will have 2 purple rectangles. And for 3 scarves : 3 * 2 = 6. Answer: She needs 6 purple rectangles.
