Answer:

Part-a: Holly will take 6 hours to complete 5 paintings
Part-b: Ella will take 2 hours longer to complete 5 paintings.

Step-by-step explanation:

We know that:

Ella = 1 3/5 = 1 painting
Holly = 1 3/5 x 3/4 = 1 painting

Work:

Holly = 8/5 x 3/4 = 1 painting
=> Holly = 2/5 x 3 = 1 painting
=> Holly = 6/5 hours = 1 painting
=> Holly = 6/5 x 5 hours = 5 paintings
=> Holly = 6 hours = 5 paintings
=> Ella = 8/5 hours = 1 painting
=> Ella = 8/5 x 5 hours = 5 paintings
=> Ella = 8 hours = 5 paintings

Final Answer(s):

Final Answer Part-a: Holly will take 6 hours to complete 5 paintings
Final Answer Part-b: Ella will take 2 hours longer to complete 5 paintings.

Hello.

Question 4:

-2.34n = -12.168
Divide both sides by -2.34;

n = 5.2 is your answer to #4 (Answer choice "C.)"

For Question 5:

-8c = 56
Divide both sides by -8 to solve for c;

c = -7 (remember your signs!) is your answer for #5 (Answer choice "C.)"

$\frac{n}{-12.168}$ = -2; To solve for this, we need to multiply both sides by -12.168 to isolate and solve for our variable.

$\frac{n}{-12.168}$ = -2; Multiply by -12.168

n = 24.336 (A negative multiplied by a negative results in a positive product.);

Your answer for #3 is n = 24.336 (Answer choice "B.)")

I hope this helps!

Write an equation for the line that passes through the given point 1. (4,-1), (0.5)

mixas84 [53]

Equation - F(x)= -x+5
Use the formula
y2-y1 5-1 4
--------- --------- ------ M = -1
X2-x1 0-4 -4

than Calculate the y-axis intercept(B) by using f(x)=mx+b
Insert -1 for m, 4 for x and 1 for f(x).

1=-1*4+1*b | Swap both sides of the equation.
1*b+-4=1 | +4
1*b=5

So, the y-axis intercept is at 5
Therefore, the equation of the function is f(x)=-x+5

Please Help Giving Brainliest!!!!! (05.06)Which net matches the solid figure shown below? A three-dimensional cube with a height

leva [86]

Answer:

A net is shown with 3 rectangles attached side by side all with width 8 centimeters and length of 7 centimeters. Attached to the middle rectangle above is a rectangle with same length and a width of 3 centimeters. Attached to the rectangle underneath are 2 more rectangles with the same length and widths of 8 centimeters and 3 centimeters.

Step-by-step explanation:

A net is a flat version of a three dimensional shape. Imagine that you have a tissue box. If you cut along the edges and laid out the pieces, you would have the net of the shape. The third choice gives the correct net that would fold back up to a rectangular solid with the given dimensions.

I hope u get what ur looking for and I wish u give me brainlist But I know u won't cuz everyone say that . But thank you so much if u put for me and It would be a very appreciated from you and again thank you so much

Sincerely Caitlin,

Thank you ☺️

Based on the figure, which of the following equations is also true?

Leno4ka [110]

Answer:

The correct answer is B.

Step-by-step explanation:

Because you know two of the angles in a triangle are 90° and 52°, you can infer that the third angle is 38°. There is a trigonometry rule that states the sine of an angle is equivalent to the cosine of 90° minus that angle, which you can apply to here. Since $Sin(52$ ° $)$ = $\frac{17}{c}$ , you know that $Cos(90$ ° $-52$ ° $)$ or $Cos(38$ ° $)$ also equals $\frac{17}{c}$ , so choice B is the correct answer.
