Help!!!!! 50 points

Answer:

A) 20x=160

B) 8 lawns

Answer:

x=16

Step-by-step explanation:

because it's a equilateral triangle and its features are

it has three equal side and

every angle has 60°

So

x=16

The value of x is equal to 16

A triangle is a polygon that has three sides and three vertices. It is one of the basic figures in geometry.

The sum of the internal angles of a triangle is equal to 180

so, 60 + 60 + m = 180

m = 180 - 120

m = 60

Since it's a equilateral triangle and its features that it has three equal side and every angle has 60°

So the three side are also equal to each other

x=16

Answer:

Yes, an x-intercept is a point in the equation where the y-value is zero, and a y-intercept is a point in the equation where the x-value is zero.

Answer:

a. Required system of equations is:

c+p = 10

5c+4p = 46

b. 6 cakes were sold

Step-by-step explanation:

Let p be the number of pies and c be the number of cakes.

Then according to given statement " the store sold 10 baked goods"

[tex]c+p = 10\ \ \ Eqn\ 1[/tex]

And

"A cake costs $5 and a pie costs $4"

[tex]5c+4p = 46\ \ \ \ Eqn\ 2[/tex]

Using equation 1,

[tex]c=10-p[/tex]

Putting this value of c in equation 2:

[tex]5(10-p)+4p = 46\\50-5p+4p = 46\\-p = 46-50\\-p = -4\\p = 4[/tex]

Putting p = 4 in equation 1

[tex]c+4 = 10\\c = 10-4\\c =6[/tex]

Hence,

a. Required system of equations is:

c+p = 10

5c+4p = 46

Answer:

80 cookies per hour

Step-by-step explanation:

First, let's make 3 1/2 a decimal, so that would be 3.5. Now lets make this problem a proportion. 280/3.5 means that Stan makes 280 cookies every 3.5 hours.

Let's simply this proportion to find the unit rate. 3.5 divided by 3.5 is 1, so dividing by 3.5 will help find the unit rate. We already did the bottom, so let's do the top. 280 divided by 3.5 is 80.

Therefore the unit rate is 80.

Answer: slope is negative 1

Step-by-step explanation:

Step-by-step explanation:

[tex] \frac{2x + 5}{4} = 9x - 11[/tex]

2x + 5 = 4(9x - 11)

2x + 5 = 36x - 44

36x - 44 = 2x + 5

36x - 2x = 5 + 44

34x = 49

x = 49/34

Answer:

x=49/34

Step-by-step explanation:

1.) Multiply both sides by 4

(4) 2x+5/4 = 9x-11 (4)

2x+5 = 36x-44

2.) Subtract 2x from both sides

2x+5 = 36x-44

    -2           -2  

5 = 34x-44

3.) Add 44 to both sides

5 = 34x-44

+44      +44

49=34x

4.) Divide by 34

49/34 = 34x/34

x=49/34

Answer:

1423100000

Step-by-step explanation:

1.65% of 1.4 billion is 23,100,000. Knowing this you just add the two numbers together to find what an extra 1.65% of people being added to the population would result in.

The current population of China is 1,423,100,000 using the compound rate of increment method.

The compound rate of increment is a type of increment that is compounded after time period it is said to be compounded. After that particular period, the increment is calculated and then added with the primary number. For the next duration, the increment is calculated on the sum.

Given, the total of population of China in 2010 was (P) = 1,400,000,000.

The rate of increase of population is (r) = 1.65%

Duration (n) = (2022 - 2010) years = 12 years.

Therefore, the total of population of China in 2022 (S)

= P(1 + r)ⁿ

= 1,400,000,000(1 + 1.65/100)¹²

= 1,400,000,000(1 + 0.0165)¹²

= 1,400,000,000(1.0165)¹²

= 1,423,100,000

Therefore, the population of China in 2022 is 1,423,100,000.

2. D  [tex]\frac{1}{2}[/tex] inch per hour

3. C    [tex]\frac{4}{5}[/tex] km

Eli chose A because he multiply 5[tex]\frac{3}{5}[/tex] km and 7 days; instead of dividing.

[tex]\frac{28}{5}[/tex] * 7= [tex]\frac{196}{5}[/tex] which is 39[tex]\frac{1}{5}[/tex]

Step-by-step explanation:

2. Divide the inches of rain by hours

12[tex]\frac{1}{4}[/tex] inches of rain ÷ 25[tex]\frac{1}{2}[/tex] hours; convert to proper fraction

[tex]\frac{49}{4}[/tex] ÷ [tex]\frac{51}{2}[/tex]

[tex]\frac{49}{4}[/tex] * [tex]\frac{2}{51}[/tex] = [tex]\frac{98}{204}[/tex] = [tex]\frac{49}{102}[/tex] which is approximately [tex]\frac{1}{2}[/tex] inch per hour

3. Divide km by days

5[tex]\frac{3}{5}[/tex] km / 7 days = [tex]\frac{28}{5}[/tex] ÷ 7 =  [tex]\frac{28}{5}[/tex] * [tex]\frac{1}{7}[/tex] = [tex]\frac{4}{5}[/tex] km

Eli chose A because he multiply 5[tex]\frac{3}{5}[/tex] km and 7 days; instead of dividing.

Answer:

Step-by-step explanation:

Reflecting D over y=1 moves it to D'(-2, 4). An additional translation of (-2, 0) is required to move it to D'(-4, 4).

The translation only affects the x-coordinate, so can occur either before or after the reflection, which only affects the y-coordinate.

The order of transformations does not matter.
