Answer 1

Answer: 6.4cm

Step-by-step explanation:

The area of a trapezoid is given as:

= 1/2(a + b)h

We then slot the given values into the formula. This will be:

1/2(15.8 + b) × 7.3 = 81.03.

7.3(15.8 + b)= 81.03 × 2

7.3(15.8 + b) = 162.06

115.34 + 7.3b = 162.06

7.3b = 162.06 - 115.34

7.3b = 46.72

b = 46.72/7.3

b = 6.4

Therefore, the answer is 6.4cm.

Which of the following options have the same value as 40% of 84?

Answers

Answer:

33.6

Step-by-step explanation:

84(0.4) = 33.6

.....

Answer:

40% of 84 is 33.6

Step-by-step explanation:

No following options are listed, but I will solve for 40% of 84

First set these up into an equation

40/100 = x/84

Cross multiply

40 × 84 = 100 × x

3360 = 100x

Divide both sides by 100 to isolate the variable

33.6 = x

What is the inverse of the function f(x)=19/x^3?

Answers

Answer:              -1

                         f    (x) =  ∛[19/x]

Step-by-step explanation:

1) Replace f(x) with y: y = 19/x^3
2) Interchange x and y: x = 19/y^3
3) Solve this result for y: xy^3 = 19, or y^3 = 19/x, or

The inverse is y = ∛[19/x]

Step-by-step explanation:

108% of what number is 34

that is equal to

108% of x = 34

108% * x  = 34

108/100 * x = 34

you can change the fraction into a reciprocal so that the variable can stand alone.

x  = 34 * 100 / 108

x = 3400/108

An artist mixes paint to make new colors.
She uses 13 cup of red paint and 13 cup of yellow paint to make a batch of orange paint.
If the artist has 2 cups of red paint available and 3 cups of yellow paint available,
how many batches of orange paint can she make?
Enter your answer in the box.

Answers

Answer:

The artist can make six batches of orange paint and it remains one cup of yellow paint

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Amount of red paint for one batch of orange paint = 1/3 of a cup

Amount of yellow paint for one batch of orange paint= 1/3 of a cup

Amount of red paint available = 2 cups

Amount of yellow paint available = 3 cups

2. How many batches of orange paint can she make?

2 cups of red paint = 6/3 = 6 batches of orange paint

3 cups of yellow paint = 9/3 = 6 batches and it remains one cup of yellow paint

The artist can make six batches of orange paint and it remains one cup of yellow paint

To find the area of a regular hexagon we use the formula

[tex]A = \frac{1}{2} ap[/tex]

a = apothem

p = perimeter

to find the peremeter we multiply the side length by the number of sides

which is 6

6x6=36 so the perimeter is 36

now we just plug it into the area of a hexagon formula

36x5.2=187.2

[tex]\frac{187}{2} =93.6[/tex]

so the area is 93.6 cm ³

The degree of the function is the highest exponent, which is 5.

The y-intercept is the value when x=0, which is 0.

The function will have 5 zeros since there are 5 distinct factors.

The end behavior will approach negative infinity as x approaches negative infinity and positive infinity as x approaches positive infinity [since the degree is odd and the leading coefficient is positive].

The roots/zeros will be at 0, 5, 3, -2, -4 [setting each factor equal to 0]
