Can someone help me with the questions in the picture?

Answer:

4 hours

Step-by-step explanation:

We can calculate this using the y=mx+c formula

y=total charge

m=per hour

x = (a) no. of hours

c= flat fee

y=20x+40

120=20x+40

We then solve like a normal equation

120-40=20x+40-40

80/20=20x/20

x=a

a=4

∴ Dalyn rents the boat for 4 hours

Answer:

D

Step-by-step explanation:

The value of the expression (-5)⁶ is,  15,625. So option D is correct

An expression is a sentence with at least two numbers or variables having mathematical operation. Maths operations can be addition, subtraction, multiplication, division.

For example, 2x+3

Given that,

The expression (-5)⁶

In mathematical terms, this means that the expression

⇒ (-5) x (-5) x (-5) x (-5) x (-5) x (-5)

⇒ 15625

So, the value of the expression (-5)⁶ is 15625.

Answer:

Step-by-step explanation:

you do base times height

Answer:

110.5 cm²

Step-by-step explanation:

The figure is composed of a rectangle with a triangle on top.

Area of rectangle = 13 × 6 = 78 cm²

Area of triangle = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )

Here b = 13 and h = 11 - 6 = 5 cm , then

A = [tex]\frac{1}{2}[/tex] × 13 × 5 = 32.5 cm°

Thus

total area = 78 + 32.5 = 110.5 cm²

Answer:

1) A honeydew has 20 more calories than a cantaloupe

Answer:

1. [tex]Perimeter = 10x^2+ 22x - 16[/tex]

2. [tex]Area = 6x^4 +28x^3 + 14x^2 - 48x[/tex]

3. [tex]x = 1[/tex] or [tex]x = -3.2[/tex]

4. [tex]Length = 0[/tex] and [tex]Width = 8[/tex]

5. [tex]Length = 6.72[/tex] and [tex]Width = 1.28[/tex]

6. Second Solution

7. [tex]Area = 8.6016[/tex]

Step-by-step explanation:

Given

[tex]Length = 3x^2 + 5x - 8[/tex]

[tex]Width = 2x^2 + 6x[/tex]

Solving (1): The perimeter

Perimeter is calculated as thus:

[tex]Perimeter = 2 * (Length + Width)[/tex]

Substitute values for Length and Width

[tex]Perimeter = 2 * (3x^2 + 5x - 8 + 2x^2 + 6x)[/tex]

Collect Like Terms

[tex]Perimeter = 2 * (3x^2+ 2x^2 + 6x + 5x - 8 )[/tex]

[tex]Perimeter = 2 * (5x^2+ 11x - 8 )[/tex]

Open Bracket

[tex]Perimeter = 10x^2+ 22x - 16[/tex]

Solving (2): The Area:

Area is calculated as thus:

[tex]Area = Length * Width[/tex]

Substitute values for Length and Width

[tex]Area = (3x^2 + 5x - 8) * (2x^2 + 6x)[/tex]

Expand Bracket

[tex]Area = 2x^2(3x^2 + 5x - 8) + 6x(3x^2 + 5x - 8)[/tex]

Open Bracket

[tex]Area = 6x^4 + 10x^3 - 16x^2 + 18x^3 + 30x^2 - 48x[/tex]

Collect Like Terms

[tex]Area = 6x^4 + 10x^3 + 18x^3 - 16x^2 + 30x^2 - 48x[/tex]

[tex]Area = 6x^4 +28x^3 + 14x^2 - 48x[/tex]

Solving (3): If perimeter is 16, show that x = 1 and x = -3.2

In (a) [tex]Perimeter = 10x^2+ 22x - 16[/tex]

Substitute 16 for Perimeter

[tex]16 = 10x^2+ 22x - 16[/tex]

Equate to 0

[tex]10x^2+ 22x - 16 -16=0[/tex]

[tex]10x^2+ 22x - 32=0[/tex]

Expand

[tex]10x^2+ 32x -10x- 32=0[/tex]

Factorize

[tex]x(10x + 32) - 1(10x + 32) = 0[/tex]

[tex](x - 1)(10x + 32) = 0[/tex]

Split

[tex]x - 1 =0[/tex] or [tex]10x + 32 = 0[/tex]

[tex]x = 1[/tex] or [tex]10x = -32[/tex]

[tex]x = 1[/tex] or [tex]x = -32/10[/tex]

[tex]x = 1[/tex] or [tex]x = -3.2[/tex]

Solving (4): Using x = 1; Solve the dimension of the rectangle

We have that:

[tex]Length = 3x^2 + 5x - 8[/tex]

[tex]Width = 2x^2 + 6x[/tex]

Substitute 1 for x in the given parameters

[tex]Length = 3(1)^2 + 5(1) - 8[/tex]

[tex]Length = 3*1 + 5*1 - 8[/tex]

[tex]Length = 3 + 5 - 8[/tex]

[tex]Length = 0[/tex]

[tex]Width = 2(1)^2 + 6(1)[/tex]

[tex]Width = 2*1 + 6*1[/tex]

[tex]Width = 2 + 6[/tex]

[tex]Width = 8[/tex]

Solving (5): Using x = -3.2; Solve the dimension of the rectangle

We have that:

[tex]Length = 3x^2 + 5x - 8[/tex]

[tex]Width = 2x^2 + 6x[/tex]

Substitute -3.2 for x in the given parameters

[tex]Length = 3(-3.2)^2 + 5(-3.2) - 8[/tex]

[tex]Length = 3*10.24 + 5(-3.2) - 8[/tex]

[tex]Length = 30.72 -16 - 8[/tex]

[tex]Length = 6.72[/tex]

[tex]Width = 2(-3.2)^2 + 6(-3.2)[/tex]

[tex]Width = 2*10.24 + 6(-3.2)[/tex]

[tex]Width = 20.48 -19.2[/tex]

[tex]Width = 1.28[/tex]

[tex]Length = 6.72[/tex] and [tex]Width = 1.28[/tex]

Solving (6):

In the first solution of the dimensions in number 4, we have that

[tex]Length = 0[/tex] and [tex]Width = 8[/tex]

This dimension can not be considered because the length of a rectangle can not be 0

In the second solution of the dimensions in number 5, we have that

[tex]Length = 6.72[/tex] and [tex]Width = 1.28[/tex]

This dimension makes more sense because both dimensions are greater than 0

Solving (7): Using (6), determine the Area

In (6), we conclude that

[tex]Length = 6.72[/tex] and [tex]Width = 1.28[/tex]

So, Area is calculated as thus:

[tex]Area = Length * Width[/tex]

[tex]Area = 6.72 * 1.28[/tex]

[tex]Area = 8.6016[/tex]

Answer:

C

Step-by-step explanation:

We know that line CD passes through the two points (0, 2) and (4, 6).

First and foremost, let’s find the slope of the line. We can use the slope formula:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Where (x₁, y₁) and (x₂, y₂) are our two points.

So, let’s let (0, 2) be (x₁, y₁) and (4, 6) be (x₂, y₂). Substitute appropriately:

[tex]\displaystyle m=\frac{6-2}{4-0}[/tex]

Evaluate:

[tex]\displaystyle m=\frac{4}{4}=1[/tex]

Hence, our slope is 1.

Now, we can use the slope-intercept form:

[tex]\displaystyle y=mx+b[/tex]

Where m is our slope and b is our y-intercept.

Notice from our given points that we are given (0, 2).

So, our y-intercept is 2.

Therefore, we will substitute 1 for m and 2 for b. This yields:

[tex]\displaystyle y=(1)x+(2)[/tex]

Simplify:

[tex]\displaystyle y=x+2[/tex]

Hence, our answer is C.

y = [tex]\frac{1}{4}[/tex] x - 2

Step-by-step explanation:

y = [tex]\frac{1}{4}[/tex] x - 2

Answer:

(f - g)(x) = 3x² - 2x - 6

General Formulas and Concepts:

Pre-Algebra

Algebra

Step-by-step explanation:

Step 1: Define

f(x) = 3x² - 2

g(x) = 2x + 4

(f - g)(x) is f(x) - g(x)

Step 2: Find

Answer:

2x - 10 = 34 degrees

3x - 10 = 56 degrees

Step-by-step explanation:

Since they're complementary, they'd equal 90-degrees.

Solve for x:

2x - 10 + 3x - 10 = 90

5x -20 = 90

5x = 110

x = 22

2(22)-10 = 34

3(22)-10 = 56

Answer:

Johnny is wrong.

Step-by-step explanation:

To compare two quantities, they must both be written in the same units. In this case, both must be in centimeters or millimeters. So, we must convert 600cm to millimeters or vice versa.

If we choose to use milimeters, we have

600cm=600cm [tex]\frac{10mm}{1cm}[/tex]

600cm = (600)(10) mm

600cm = 6000 mm

Now, we must compare 6000 mm with 5642 mm. We can see that 6000mm is greater than 5642 mm. hence, it is enough moulding for the baseboards.

In fact, 6000-5642 mm =358 mm would remain.

Step-by-step explanation:

If A=650+135N; and B=585N,

then A+B= 650+135N+585N=650+620N

T=720N+650

A function assigns values to each element. An equation relating T to N can be represented by T=650+720N.

A function assigns the value of each element of one set to the other specific element of another set.

The function which tells the amount that is been saved by Jina is given by the function A=650+135N, while the function which tells the amount that will be saved by her husband is B=585N.

Since the total saving amount is represented by T which is the sum of the two functions A and B. Therefore, the function of T can be written as,

[tex]\rm T=A+B\\\\T = (650+135N)+585N\\\\T = 650+135N+585N\\\\T = 650+720N[/tex]

Thus, an equation relating T to N can be represented by T=650+720N.

Answer:

[(6 + x) / 13+x] = 0.65

7

Step-by-step explanation:

Given that:

Total number of games = 13

Number of correct prediction = 6

Number of correct predictions needed to raise prediction % to 65%

(Number of correct predictions) / (total number of games) = 0.65

Let x = number of additional consecutive correct predictions

[(6 + x) / 13+x] = 0.65

Where x = number of consecutive predictions required

6 + x = (13 + x) * 0.65

6 + x = 8.45 + 0.65x

x - 0.65x = 8.45 - 6

0.35x = 2.45

x = 2.45 / 0.35

x = 7

Tan J = 0.2917

Step-by-step explanation:

Here, we want to find the value of tan J

Firstly, we need to understand that the numbers 24, 25 and 7 are a Pythagorean triple and as such the three measures represent the values of length of the sides of a right angled triangle

The tangent of an angle= measure of the opposite/measure of the adjacent

In the question, the opposite to point J measures 7 while the adjacent measures 24

So ;

tan J = 7/24

= 0.2917
