Answer:

x = 28

m∠ACD = 68°

Step-by-step explanation:

∠BAE ≅∠DAC because they are vertical angles

∠ACD = 180 - 124 = 56°

to find 'x':   56 + 2x + (180 - 4x) = 180

236 - 2x = 180

-2x = -56

x = 28

m∠ACD = 180 - 4(28)  =  180 - 112  =  68°

Answer: (x-6)(x+1)

Step-by-step explanation:

Sum :  x2 − 5  x- 6

x2 + x-=6 x − 6

factor pair: x  2 + x − 6 x − 6

x( x+ 1 ) − 6 ( x + 1 )

rewrite from: x (x  + 1 ) − 6 ( x + 1 )

(x-6)(x+1)

Answer:

A: (x-6)(x+1)

Step-by-step explanation:

We need to find 2 numbers that add to make -5 and multiply to make -6.

We already have the numbers infront of us, so by process of elimination we can remove B and D.

For the numbers, we need a positive number and a negative number (two negatives make a positive). We can eliminate C because at first -3 multiplied by 2 is -6. However, when -3 is added to 2 we get -1.

If we expand A, it makes the expression that needs to be factorised because...

-6 × 1 = -6

-6 + 1 = -5

So expanding it properly we get.

x² - 6x + x - 6

Simplify.

x² - 5x -6

Answer:

infinitely many solutions

Step-by-step explanation:

Given the simultaneous equation

4x=10+4y... 1

2x-2y=15 .... 2

_____________

4x-4y = 10 * 1

2x-2y = 15 * 2

__________--

4x-4y = 10

4x-4y = 30

Add both equation

8x - 8y = 10+30

8x-8y = 40

Divide though by 8

x-y = 5

x = 5 +  y

Since the result gave 1 equation and 2 unknowns, then we will let x =k

k = 5 + y

y = k -5

k can be any integer

(x,y) = (k, k-5)

This show that the equation has infinitely many solutions

Answer:

Yes by SAS

Step-by-step explanation:

if you do 42 / 18 you see that the relationship between the sides is 2.3333... so that is one proportional side

Then, you see that there is one angle in both triangles that is 76 degrees, so that is one equal angle

then, you can do 21 / 9 = 2.33333... which is the same as the first proportion which means that is another proportional side.

then you have a side, angle, and a side, so it's SAS

Answer:

d. V = 668.2 ft³

Step-by-step explanation:

[tex]V = \frac{1}{2}bhl\\V = \frac{1}{2}(8.6)(8.4)(18.5)\\V = 668.2ft^{3}[/tex]

Answer:

[tex]\boxed {\boxed {\sf D. \ V \approx 668.2 \ ft^3}}[/tex]

Step-by-step explanation:

The volume of a triangular prism is found using this formula:

[tex]V=\frac{1}{2} bhl[/tex]

For this prism, the base is 8.6 feet, the height is 8.4 feet, and the length is 18.5 feet.

[tex]b= 8.6 \ ft \\h= 8.4 \ ft \\l= 18.5 \ ft[/tex]

Substitute the values into the formula.

[tex]V= \frac{1}{2} (8.6 \ ft) (8.4 \ ft) ( 18.5 \ ft)[/tex]

Multiply the first two numbers in parentheses.

[tex]V= \frac{1}{2} (72.24 \ ft^2) ( 18.5 \ ft)[/tex]

Multiply again.

[tex]V= \frac{ 1}{2} (1336.44 \ ft^3)[/tex]

Multiply by 1/2 or divide by 2.

[tex]V= 668.22 \ ft^3[/tex]

Round to the nearest tenth. The 2 in the hundredth place tells us to leave the 2 in the tenth place.

[tex]V \approx 668.2 \ ft^3[/tex]

The volume is about 668.2 cubic feet.

Hope that helps!

If x is an odd integer and 2y is an even integer then K. 2y  x is odd.

Odd + Odd = Even.

Odd + Even = Even + Odd = )dd.

Even + Even = Even.

Odd × Odd = Even.

Even × Even = Even.

Odd × Even = Even × Odd = Odd.

Odd ÷ Odd = Even.

Even ÷ Odd = Even Or Odd.

Odd ÷ Even = Fraction/Decimal.

Given, x is an odd integer and 2y is an even integer.

So, y can be even or odd we are not sure.

Therefore, the only option that must be true is 2y + x is odd.

Answer:

d= 1/ 4

Step-by-step explanation:

Answer: 1/4

Step-by-step explanation:

-16(d + 1) = -20

-16d - 16 = -20

-16d - 16 + 16 = -20 + 16

-16d = -4

-16d/-16 = -4/-16

Answer:

B. 2 years

Step-by-step explanation:

use y = mx + b

y = total number of sell outs = 168

m = sell outs per month = 7

x = months

b is not needed for this

168 = 7x

divide both sides by 7

x = 24

divide 24 by 12 to get the number of years

years = 2

the answer to this question is B. 2 years

Answer:

increase by the percent

The fraction will decrease by 20%.

A fraction represents a part of a whole.

Let's assume the original fraction to be x/y.

If we increase the numerator by 20%, it becomes 1.2x.

If we increase the denominator by 50%, it becomes 1.5y.

So, the new fraction will be:

(1.2x) / (1.5y)

Simplifying this expression, we get:

(4x/5y)

The new fraction is (4/5) times the original fraction.

Therefore, the fraction will decrease by 20%.

Answer: 5

Step-by-step explanation:

each banana split is equal to 2 lbs. therefore, to gain 10 lbs. you need to eat 5 banana splits.

500cal = 1 lb.

1000cal = 1 banana split

1 banana split = 2lbs.

to gain 10lbs, divide 10lbs by 2lbs = 5 banana splits

Answer:the nth term of the sequence, Tn= -3n +12

Step-by-step explanation:

The nth term of an arithmetic progression is given as

Tn=  a+ (n-1) d

where a= first term

and d = common difference

In this sequence, 9, 6 ,3 ,0, -3, -6 we can see that  the number is decreasing by 3

The first term, a= 9

and common difference, d = -3

using our formulae

Tn=  a+ (n-1) d

Tn= 9 + ( n-1) -3

Tn=9- 3n+ 3

Tn= -3n +12

Answer:

y int= 12.50

slope= 2.00

equation= y=2x+12.5

Step-by-step explanation:

the y intercept in this case is the cost when you've watched 0 movies- its the initial price you pay, or the y value when the x value is equal to 0

the slope is the cost of each movie, or the increment by which the y values goes up when the x value goes up by 1 in this case. (for example the slope would be 5 if the movie price were 5 for each one movie)

y=mx+b is the equation for a linear equation, where m is the slope and b is the y intercept.

Answer:

Larger building is 4 meters taller than smaller building.

Step-by-step explanation:

Formula to get the height 'x' of a building having volume = x³ is,

x = [tex]\sqrt[3]{\text{Volume of the building}}[/tex]

Height of the smaller building,

[tex]x_1=\sqrt[3]{1}[/tex]

[tex]x_1=1[/tex]

Similarly, height of the larger building = [tex]\sqrt[3]{125}[/tex]

                                                               = [tex]\sqrt[3]{5^3}[/tex]

                                                               = 5 meters

Difference in the heights of the buildings = 5 - 1

                                                                     = 4 meters

Therefore, difference is the height of larger and smaller building is 4 meters.
