Answer:

3

Step-by-step explanation:

The two quads are of similar, and we know that they are of ratio 1:2, thus

3y+5/7 = 2

y = 3

Answer:

y = 3

Step-by-step explanation:

The figures are similar so the ratios of corresponding sides are equal, that is

[tex]\frac{UR}{DA}[/tex] = [tex]\frac{TS}{CB}[/tex] , substitute values

[tex]\frac{4}{2}[/tex] = [tex]\frac{3y+5}{7}[/tex] ( cross- multiply )

2(3y + 5) = 28 ( divide both sides by 2 )

3y + 5 = 14 ( subtract 5 from both sides )

3y = 9 ( divide both sides by 3 )

y = 3

Answer:

x=105

Step-by-step explanation:

75+75+x+x=360

150+2x=360

2x=210

x=105

I hope this is correct and helps you!

Answer:

x = 105°

Step-by-step explanation:

Because x° and 75° are supplementary angles (sum equals 180°), we cand do 180° - 75° to find x.

180° - 75° = x

x = 105°

Answer:

B. 3.5 feet

Step-by-step explanation:

The part leaning against the wall is the hypotenuse while the height of the ladder off the ground is the opposite and the distance of the ladder from the house is the adjacent side.

Given the following data;

Hypotenuse = 12.5 ft

Opposite = 12 ft

To find the adjacent side, we would use the Pythagorean theorem;

Hypotenuse² = opposite² + adjacent²

Substituting into the formula, we have;

12.5² = 12² + adjacent²

156.25 = 144 + adjacent²

Adjacent² = 156.25 - 144

Adjacent² = 12.25

Taking the square root of both sides, we have;

Adjacent = 3.5 feet.

Therefore, the distance of the ladder from the house is 3.5 feet.

Missing part of question

(a) (-3, 4) and (5, 4)

(b) (4, 5) and (4, -3).

Answer:

(a) (-3, 4) and (5, 4)

Zero slope

Horizontal line

(b) (4, 5) and (4, -3).

Undefined slope

Vertical line

Step-by-step explanation:

Solving (a): (-3, 4) and (5, 4)

Slope (m) is calculated as:

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

This gives

[tex]m = \frac{4-4}{5 - -3}[/tex]

[tex]m = \frac{0}{8}[/tex]

[tex]m = 0[/tex]

This line has a slope of zero.

When slope equals 0, then the line is horizontal

Solving (b): (4, 5) and (4, -3)

Slope (m) is calculated as:

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

This gives

[tex]m = \frac{5--3}{4-4}[/tex]

[tex]m = \frac{8}{0}[/tex]

m = undefined

This line has an undefined slope.

When the slope of a line is undefined, then the line is vertical

Answer:

A

Step-by-step explanation:

We have to determine the future value of the annuity to determine which account has a greater value

Future value = Amount x annuity factor

annuity factor = Annuity factor = {[(1+r)^n] - 1} / r

Account A = 300 x[ (1.042)^15 - 1 ] / 0.042 = $6097.14

Account B = 250  x[ (1.051)^15 - 1 ] / 0.051 = $5435,42

Account A will be greater

Answer:this one is hard

Step-by-step explanation:

Answer:

x = 8

Step-by-step explanation:

f(x) = [tex]\sqrt{3x}[/tex]

g(x) = [tex]\frac{1}{x+3}[/tex]

(f o g)(x) = f[g(x)]

             = [tex]\sqrt{\frac{3}{x+3} }[/tex]

This function is defined for (x + 3) > 0

(x + 3) - 3 > 0 - 3

x > -3

From the given options x = 8 is the only solution which is greater than -3.

Therefore, x - 8 is in the domain of the given function.

Answer:

2x is less than 8 or B

Step-by-step explanation:

When looking at the number line you got to look to see if the circle is closed or not. In this case it is a closed circle meaning to include the number. Then look at what direction it is going toward. Is it increasing? Is it decreasing? In this case it is decreasing. Meaning that 2x is less than 8

NOT A - Reason why it is not a is because 8 is not included in the range of numbers

NOT C

Answer:

x=-8

Step-by-step explanation:

3x + y =19

-6x - 5 = y

3x + y =19

-6x -y=5

-3x=24

x=-8

y= -6x -5

y=48-5=43

Answer:

350

Step-by-step explanation:

2(lw + wh + lh)

(7*7) = 49

(7*9) = 63

(9*7) = 63

so now its

2(49 + 63 + 63)

= 2(175)

= 350

have agreat day and easter :)

Answer:

The side lengths are 10 by 7

Step-by-step explanation:

The area of a rectangle is

A = l*w

70 = (x - 11)(x - 8)

FOIL

70 = x^2 -8x-11x+88

Combine like terms

70 = x^2 -19x +88

Subtract 70 from each side

0 = x^2 -19x +88-70

0 = x^2 -19x+18

Factor

What number multiplies to 18 and adds to -19

-18*-1 =18

-18-1 = -19

0=(x-18)(x-1)

Using the zero product property

x-18=0   x-1=0

x=18   x=1

But x cannot x=1 because then the side lengths would be negative

x-18 = 10

x-11 = 7

The side lengths are 10 by 7

Answer:

Simplify each term.

Px+px+3p=10x−7

Move all terms not containing P to the right side of the equation.

Px=10x−7−px−3p

Divide each term by x and simplify.

P=10−7/x−p−3p/x

Step-by-step explanation:

Hello There!

The area of a rectangle is equal to length times width

2*9=18 so the area of the rectangle is 18 square feet

If a triangle is formed in a rectangle then that triangle is 1 half of the area of the rectangle

18/2=9 so the area of the triangle is 9 square feet
