The volume of the model building is cubic foot?

Step-by-step explanation:

[tex]56 + 51 + y = 180 \\ y = 180 - 107 \\ y = 73[/tex]

[tex]y + x + 72 = 180 \\ 73 + 72 + x = 180 \\ x = 180 - 145 \\ x = 35[/tex]

Hope it helps

A straight angle is an angle equal to 180 degrees

Solve for y

y + 51° + 56° = 180°

y = 180° - 56° - 51°

y = 73°

Total interior angle of a triangle sum ups to 180°

Solve for x

y + x + 72° = 180°

73° + x+ 72° = 180°

x = 180° - 72° - 73°

x = 35°

Answer:

I only know number 2 sorry

Answer:

Yes

Step-by-step explanation:

A right triangle has to have one 90 degree angle and all triangle angles must add up to 180 degrees.

27+63= 90

180-90= 90

So to answer your question, the triangle is a right triangle.

If the campaign of Snyder’s Moving company costs $500 to execute, it has been computed that the profit will be C. $50,480.

Firstly, the customer base will be:

= 50% × [2200 - (10% × 2200)]

= 50% × (2200 - 220)

= 990

The increase in customers will be:

= 10% × 990

= 99

The additional profit will be:

= [(99 × $260) - $500] × 2

= ($25740 - $500) × 2

= $50480

Answer:

10% SB clients will move due to the promotion. The Profit will be $25,240

Step-by-step explanation:

Find the number of clients in both SB and personal:

10% x 2200 = 220

Find the number of SB clients:

(2200 - 220)/2 = 990 ( the rest of clients will be evenly splitted)

Find the number of SB clients who will move:

10% x 990 = 99

Find the profit due to the move:  (Number of ppl moved  x Average Profit - Initial Investment)

99 x $260 - $500 = $25,240

Answer:

y=5x+3

Step-by-step explanation:

Hi there!

We are given that a line has a slope of 5, and a y intercept of (0,3)

We want to write the equation of this line in slope-intercept form

Slope-intercept form is written as y=mx+b, where m is the slope and b is the value of y at the y intercept

Since we were given the slope and the y intercept, we can simply substitute these values into the formula to find the equation.

Starting with the slope:

Substitute 5 as m into the equation

y=5x+b

Now for the y intercept:
As stated before, b is the value of y at the y intercept; in this case, b is equal to 3

Substitute 3 as b into the equation.

y=5x+3

Answer:

There are two ways to do this depending on the information you know.

Step-by-step explanation:

In order for a quadrilateral to be a rhombus, the sides have to be of equal length, so proving that all four sides are the same length would be one way. A second way is to prove that diagonals connecting opposite corners are perpendicular bisectors (connect in such a way that they cut each other into equal pieces at right angles).

Answer:

7/5

Step-by-step explanation:

12x - 15 =6 - 3x

Add 3x to each side

12x+3x - 15 =6 - 3x+3x

15x -15 = 6

Add 15 to each side

15x -15+15 = 6+15

Divide by 15

15x/15 =21/15

x = 7/5

Answer:

[tex]\boxed{x = \dfrac{7}{5}}[/tex]

Step-by-step explanation:

Given equation:

[tex]12x - 15 = 6 - 3x[/tex]

To solve for x, we need to isolate the "x" variable on one side of the equation. The constant obtained on the other side of the equation will be the solution (x).

Add 15 both sides of the equation:

[tex]\implies 12x - 15 + 15 = 6 - 3x + 15[/tex]

[tex]\implies 12x = 21 - 3x[/tex]

Add 3x both sides of the equation:

[tex]\implies 12x + 3x= 21 - 3x + 3x[/tex]

[tex]\implies 15x= 21[/tex]

Divide both sides by 15 to isolate the cooeficient from "x".

[tex]\implies \dfrac{ 15x}{15} = \dfrac{21}{15}[/tex]

[tex]\implies x = \dfrac{21}{15}[/tex]

Simplify the value of "x" as required:

[tex]\implies x = \dfrac{7 \times 3}{5 \times 3}[/tex]

[tex]\implies \boxed{x = \dfrac{7}{5}}[/tex]

Answer:

     x(x +3) = 108

Step-by-step explanation:

The longer string is 3 inches longer than the shorter string, whose length is x. Then the longer string is (x+3), and the product of their lengths is ...

  x(x +3) = 108 . . . . . equation for finding the shorter length

__

In standard form, the equation is ...

  x² +3x -108 = 0

  (x -9)(x +12) = 0 . . . . . factored form

The values of x that make these factors zero are 9 and -12. The shorter string length is 9 inches.

_____

Additional comments

John's guitar is unusually small if its strings are 12 inches or less.

Note that factoring is accomplished by finding factors of 108 that differ by 3. This requires the same thinking process as solving the problem directly without the use of an equation. We know the product of two numbers is 108 and one is 3 larger than the other.

The difference (3) is sufficiently smaller than the product that the square root of the product (10.4) will be about halfway between the numbers. We can reasonably guess their values to be 10.5±3/2 = {9, 12}. (There is a more formal way to make this calculation by defining a variable (a) to be the average of the two lengths: Then you have (a-3/2)(a+3/2)=108, or a² = 110.25 and a=10.5. This matches our approximation.)

Using the t-distribution, as we have the standard deviation for the sample, it is found that the 95% confidence interval is (29.6, 44.4).

The confidence interval is:

In which:

The critical value, using a t-distribution calculator, for a two-tailed 95% confidence interval, with 25 - 1 = 24 df, is t = 2.0639.

The other parameters are given by:

[tex]\overline{x} = 37, s = 18, n = 25[/tex].

Hence, the bounds of the interval are given as follows:

[tex]\overline{x} + t\frac{s}{\sqrt{n}} = 37 + 2.0639\frac{18}{5} = 44.4[/tex]

= 981.496  ft^3

Answer:

Area of a triangle is 1/2 x base x height.

area of triangle = 1/2 x 20 x 17 = 170 square feet.
