The sum of two numbers is 18. 5 times the first number subtracted from 4/7 of the second number is 14. Find the number.

Answers

Answer:

The sum of two numbers is 18.

5 times the first number subtracted from 4/7 of the second number is 14.

First number --> x

Second number --> y

so

x + y = 18 --> x = 18-y

5x - (4/7)y = 14

so

5 (18-y) - (4/7)y = 14

90 - 5y - 4/7 y = 14

-5.57 y = 14-90

y = 13.64

so

x = 18 - 13.64

x = 4.36

A streetlight that is 10 feet tall casts a 2.5-foot-long shadow. A nearby flagpole casts a 9-foot-long shadow. What is the height of the flagpole?

Answers

Answer:

The height of the flagpole is 36 feet

Step-by-step explanation:

The given parameters are;

The height of the street light = 10 feet

The shadow cast by the streetlight = 2.5 feet

The shadow cast by the flagpole = 9 foot

The height of the flagpole is given as follows;

The height of the street light/(The shadow cast by the streetlight) = (The height of the flagpole)/(The shadow cast by the flagpole)

∴ The height of the flagpole = (The shadow cast by the flagpole) × (The height of the street light)/(The shadow cast by the streetlight)

By substituting the values, we get;

The height of the flagpole = 9 ft. × 10 ft./2.5 ft. = 36 feet

The height of the flagpole = 36 feet.

The plans for a new street show lamp post that are 2.5 inches apart. If the plans use a scale of 0.5 inch = 9 yards, find the actual distance between the lamp posts.

Answers

Answer: 45 yards

Step-by-step explanation:

From the question, we are given the information that the plans for a new street show lamp post that are 2.5 inches apart and that the plans use a scale of 0.5 inch = 9 yards,

Since a scale of 0.5 inch = 9 yards is used, the actual distance between the lamp posts will be:

= (2.5inches / 0.5 inches) × 9 yards

= 5 × 9 yards

= 45 yards

1. Andrew went to FYE to buy music for the band. He spent a total of $112 on 14 music purchases. one Music CDs were on sale for $10 and cassettes were on sale for $3. How much did Andrew pay for each music CD and each cassette tape? Enter your one-sentence interpretation in the space below.​

Answers

Answer:

Total Money spent on Music CDs = 10 [tex]\times[/tex] 10 = $100

Total Money spent on Cassette tapes = 4 [tex]\times[/tex] 3 = $12

Step-by-step explanation:

Given that:

Total money spent = $112

Number of music purchases = 14

Cost of one Music CD = $10

Cost of one cassette = $3

To find:

How much money was paid for each music CD and each cassette.

Solution:

Let the number of Music CDs purchased = [tex]x[/tex]

Money spent on Music CDs = [tex]\$10\times x[/tex]

Then the number of cassette tapes purchased = [tex]14-x[/tex]

Money spent on cassette tapes = [tex]\$3\times (14-x)[/tex]

As per the question statement:

[tex]10x+3(14-x)=112\\\Rightarrow 10x+42-3x=112\\\Rightarrow 7x=112-42\\\Rightarrow 7x=70\\\Rightarrow x =10[/tex]

Therefore, number of Music CDs purchased = 10

Total Money spent on Music CDs = 10 [tex]\times[/tex] 10 = $100

And number of cassette tapes purchased = 14 - 10 = 4

Total Money spent on Cassette tapes = 4 [tex]\times[/tex] 3 = $12

Using the Pythagorean Theorem, it is found that the side length is of x = 6.93.

What is the Pythagorean Theorem?

The Pythagorean Theorem relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, according to the following equation:

[tex]h^2 = l_1^2 + l_2^2[/tex]

In this problem, we have that:

[tex]h = 13, l_1 = 11, l_2 = x[/tex]

Hence, applying the Theorem:

[tex]h^2 = l_1^2 + l_2^2[/tex]

[tex]13^2 = 11^2 + x^2[/tex]

[tex]x^2 = 169 - 121[/tex]

[tex]x = \sqrt{48}[/tex]

x = 6.93.

Answers

Answer:21.50 dollars

Step-by-step explanation:

The customer pays an amount of $26.74 for one pair of binoculars and one bird guide after the mark-up and 8.5% sales tax

What is the percentage?

The percentage is defined as a ratio expressed as a fraction of 100.

According to the given, the required solution would be as:

Mark up for binoculars = 10 x 1.45 = 14.50

14.5 x 1.085 = 15.7325 in sales tax

The total cost per binocular is $15.73 ($).

Bird Guide Commission = 7 x 1.45 = 10.15

10.15 x 1.085 = 11.01275 Sales Tax

The total cost per Bird Guide is $11.11 ($).

The addition provides one of each.

⇒ 15.73 + 11.01 = 26.74

Thus, the customer pays an amount of $26.74 for one pair of binoculars and one bird guide after the mark-up and 8.5% sales tax

A scale drawing of a rectangular flag is 12 inches long and 8 inches wide. If the scale is 1 inch: 2.4 feet, what is the length and width of the actual flag?

Answers

Answer: length = 28.80 feet

Width = 19.20 feet

Step-by-step explanation:

Scale used = 1 inch:2.4 feet

Length or scale drawing = 12 inches

Width of scale drawing = 8 inches

Length of actual flag = (12 × 2.4 feet) = 28.80 feet

Width of actual flag = (8 × 2.4 feet) = 19.20 feet.

Answer:Answer: length = 28.80 feet

Width = 19.20 feet

Step-by-step explanation

Scale used = 1 inch:2.4 feet

Length or scale drawing = 12 inches

Width of scale drawing = 8 inches

Length of actual flag = (12 × 2.4 feet) = 28.80 feet

Width of actual flag = (8 × 2.4 feet) = 19.20 feet.

Answers

Answer:

y= 3/5x + 3

Step-by-step explanation:

slope= 3/5

y intercept= 3

Answer: [tex]y=\frac{3}{5} x+3[/tex]

Step-by-step explanation:

To find the equation of the graph, we need to know the slope and y-intercept. We can find the slope by using the formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]. Then, we use a point to find the y-intercept. Let's use the points (0,3) and (-5,0).

[tex]m=\frac{0-3}{-5-0} =\frac{-3}{-5} =\frac{3}{5}[/tex]

Now that we know the slope, we can plug in any point to find the y-intercept.

[tex]3=\frac{3}{5} (0)+b[/tex]            [multiply]

[tex]b=3[/tex]

Now, we know the equation is [tex]y=\frac{3}{5} x+3[/tex].

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
