Answer:

<u> The total amount = $175</u>

Step-by-step explanation:

Let the total amount in his bank account = x

Nick decided to take 2/5 of the money in his bank account and donate it to a local charity

So, he donates with \frac{2}{5} x

If nick donated $70 to a local charity

so, \frac{2}{5} x = 70

solve for x

∴ x = 5*70/2 = 350/2 = $175

<u>So, The total amount = $175</u>

f(x)=8−4x−x3 g(x)=x2+7x−9 Find f(x)+g(x). Select one: a. x3+x2+3x−1 b. −x3+x+3x−1 c. −x3+x2+11x−9 d. 8x2+3x−9x3
vovangra [49]

Answer:

B

Step-by-step explanation:

We are given the two functions:

f(x) = 8 - 4x - x^3\text{ and } g(x) = x^2 + 7x - 9

And we want to find:

f(x) + g(x)

Substitute:

= (8 - 4x - x^3) + (x^2 + 7x - 9)

Rewrite:

= (-x^3) + (x^2) + (7x - 4x) + (8 - 9)

Combine like terms:

= -x^3 + x^2 +3x -1

In conclusion:

f(x) + g(x) =  -x^3 + x^2 +3x -1

Hence, our answer is B.

Altitudes $\overline{ax}$ and $\overline{by}$ of acute triangle $abc$ intersect at $h$. if $\angle ahb = 132^\circ$, then what i
Sergio [31]
Answer: 48 degrees

-------------------------------------------------------

See the attached image for a visual of the problem and answer.

Based on the diagram, we have angle AHB = 132 degrees (given) equal in measure to angle XHY since these two angles are vertical angles. 

Angles HYC and HXC are right angles due to the nature of AX and BY being altitudes. Recall that altitudes are segments that go from one vertex to the opposite side and they are perpendicular to the opposite side.

Focus on quadrilateral HXCY. So far, we know that...
Angle XHY = 132 degrees
Angle HYC = 90 degrees
Angle HXC = 90 degrees

The angle we want to find is angle ACB, which is the same as angle YCX. This angle is the missing angle of the quadrilateral HXCY.

For any quadrilateral, the four angles must add to 360 degrees. 

(angle XHY) + (angle HYC) + (angle HXC) + (angle YCX) = 360
(132) + (90) + (90) + (angle YCX) = 360
312 + (angle YCX) = 360
312 + (angle YCX) - 312 = 360 - 312
angle YCX = 48 degrees

Since angle ACB is the same as angle YCX, we can say
angle ACB = angle YCX = 48 degrees

So in summary,
angle ACB = 48 degrees

A children's birthday party at an indoor play center costs $50 to rent the space and $6.25 per child. Gina wants to spend no mor
kobusy [5.1K]
A.) <span>50 + 6.25x ≤ 100; x ≤ 8

There is a flat rate of $50 and 6.25 per child. This would be written as 50 + 6.25x . It has to be less than or equal to $100, since the directions state that you cannot pay more than $100. 

Then you would solve the inequality. 

Subtract 50 from both sides so the inequality looks like this: 

6.25x </span>≤ 50

Then, divide 6.25 from 50. You should get x≤8.

sveticcg [70]
1 yard=36".
25 yeards = 25*36" = 900"
3 rolls = 3*900 =  2700"
Each piece must be 22" long, so the number of pieces
= 2700/22 = 122 pieces (2684") with 16" left over.

Help me ASAP... PLISSSSS​
Marina CMI [18]

Answer:

1010 base 9 Changing from base to decimal we start from left side digit and multiply by base

1000 * 9^3 = 729

1 * 9 = 9

We sum and get 738

85 base 9 =

8 * 9 = 72

5 = 5

We sum 72 + 5 = 77 decimal

738 - 77 = 661 decimal

and if the answer must be in base 9 then:

661 decimal = 814 base 9
