How many terms are in the binomial (a+b)^8 ? __

What is the value of h in the diagram below? If necessary, round your answer

Nookie1986 [14]

Answer:

I believe the answer would be B. 9.1

Step-by-step explanation:

I am not 100% sure this is correct since I haven't done a problem like this in years but i'm like 90% sure.

The CBGC pays college and high school students $5.75 per hour to tutor the younger boys and girls. If one of those tutors works

Levart [38]

Answer:

1. $35.075

2. 43.5 hours

3. 70%

4. Danny is correct

5. Abe's score out of the 30 points of the last quiz to get an overall checkup quiz grade of 80% should be 28.5

Step-by-step explanation:

The pay per hour for student tutors = $5.75

1. A tutor who worked 3.4 hours on Monday and 2.7 hours on Thursday has worked, 3.4 + 2.7 = 6.1 hours for the week, therefore

The week earning for the tutor = 6.1 × 5.75 = $35.075

2. The Club's tutoring budget per week = $250

The number of tutoring hours that can be provided per week is given by the relation;

$\frac{The \, Club's \ tutoring\ budget \ per \, week}{The \, pay \ per \, hour\, for\, student\, tutors} = \frac{\$250}{\$5.75/hour} = 43.47826 \approx 43.5 \, hours$

3. The score of 21 out of 30 as a percentage is given as follows;

$\frac{21}{30} \times 100 = 70\%$

4. Where the second score is 45 out of a total of 60 points, we have;

$\frac{45}{60} \times 100 = 75\%$

Therefore, the increase in Abe's score is 5%, therefore, Danny is correct

5. To raise his checkup quiz grade to 80% overall, then we should have;

$\frac{70 + 75 + Q}{300} =\frac{80}{100}$

Where:

Q = The percentage grade of the last quiz

(145 + Q)×100 = 80×300 = 24000

145 + Q = 240

Q = 240 - 145 = 95%

Therefore, he has to score, 95% of 30 on the last quiz, which is thus;

$\frac{95}{100} \times 30 = 28.5$

Abe's score out of the 30 points of the last quiz to get an overall checkup quiz grade of 80% = 28.5 points.

A painter is using a 8-foot ladder to paint a house. The painter places the ladder 6 feet from the house. How high up the wall d

9966 [12]

Step-by-step explanation:

step 1. This is a right triangle where a^2 + b^2 = c^2 (c is the hypotenuse).

step 2. a^2 + 6^2 = 8^2.

step 3. a^2 = 64 - 36.

step 4. a^2 = 28.

step 5. a (the ladder height along the wall) = sqrt (28) where sqrt is the square root.

step 6. sqrt(28) = 2(sqrt(7)).

You move down 1 units and up 2 units. You end at (-3,1). Where did you start? On a number graph 1 through 5 axis graph

Roman55 [17]

Let's do it step by step:

First we need to understand that moving upwards would be addition to y-coordinates, while moving downwards would be deduction to the y-coordinates.

Moving to rightwards would be addition to x-coordinates and leftwards would be deduction to x-coordinates.

As we moved down by 1 unit and up for 2 units, it means that we are originally upward for one unit and downward by 2 units, which makes downwards for 1 units and would be -1 to the y-coordinates:

(-3,1 -1)

=(-3,0)

Therefore the start would be (-3,0).

Hope it helps!
