Answer:

60

Step-by-step explanation:

Chyna is taking a test, for now, she has completed 15 questions. The amount of questions she completed in percentage is 25%. The question is asking how many questions are on the test, so first we need to find how we can get 25% to 100%, then what we did for that to happen we would also apply it to the 15 questions Chyna has already taken.

So 25% multiplied by 4 equals 100%.

Therefore meaning that we need to multiply 4 by 15 to get our answer.

15 * 4

60

This means that the test has 60 questions in total.

The third term of an arithmetic sequence is-8, and the sum of the first 10 terms of the sequence is -230. Find:
mixas84 [53]

Answer:

The first term of the sequence is a = 4

The sum of the first 13 terms is -480

Step-by-step explanation:

Given that:

The third term is: a + 2d = - 8 --- (1)

The \  sum  \ of  \ the \  first \ 10  \ terms  \ is:

-230 = \dfrac{10}{2}[2a+ (10-1)d]

-230 =5[2a+ (9)d]

-230 = 10a + 45d

10a + 45d = -230     ----(2)

From (1) and (2)

a + 2d = - 8

10a + 45d = -230

From (1), let a = -8 - 2d

Replace, the value of a in (1) to equation (2)

10(-8 -2d) + 45d = -230

-80 -20d +45d =-230

25d = -230 + 80

25d = -150

d = -150/25

d = -6

From equation (1);

a + 2(-6) = -8

a -12 = -8

a = -8 + 12

a = 4

Thus,the first term of the sequence a = 4

The \  sum  \ of  \ the \  first \ 13  \ terms  \ is:

S_n = \dfrac{n}{2}[2a+(n-1)d]

S_n = \dfrac{13}{2}[2(4)+(13-1)*-6]

S_n =7.5 [8+(12)\times -6]

S_n =7.5 [8-72]

= -480

What is the equation for the line with slope m=−4 and y-intercept b=3
andreev551 [17]

Answer:

ok so i am going to give you a litle saying to help you remember the way it goes ok. this problem is in slope-intercept form

"y=mx+b,,b is my y-intercept you'll see,m is my slope which is rise over run"

so if -4 is your slope it will go where the m is in the formula y=mx+b so it would now be y=-4x+b and then the b is your y-intercept so 3 would go where the b is in the formula now now since we plugged in all the parts.

<u>the answer is y=-4x+3 </u>
