Solve For X Please :)

Answers

Answer 1

Answer:

x = 10

Step-by-step explanation:

Assuming the 2 figures are similar, then the ratios of corresponding sides are equal, that is

[tex]\frac{5}{x}[/tex] = [tex]\frac{4}{8}[/tex] ( cross- multiply )

4x = 40 ( divide both sides by 4 )

x = 10

Toby skated from his house to the beach at a constant speed of 888 kilometers per hour, and then skated from the beach to the park at a constant speed of 777 kilometers per hour. The total distance Toby skated was 202020 kilometers, and it took him twice as long to get to the park. Let bbb be the number of hours it took Toby to skate from his house to the beach, and ppp the number of hours it took him to skate from the beach to the park. Which system of equations represents this situation?

Answers

Answer:

8b+7p=20

p = 2b

Step-by-step explanation:

Given that there is a constant speed of 8 km per hour and the number of hours be b so here 8b signifies the distance

Now on the other hand there is a constant speed of 7 km per hour and the number of hours be p so here 7p signfies the distance

So the total distance would be

= 8b + 7p

And, the total km is 20

Now the whole equation would be

8b + 7p = 20

Also it is mentoined that for getting into the park it is twice for getting into the beach

So, it would be

p = 2b

Therefore the system of equations are as follows

8b+7p=20

p = 2b

What was Sharon's error in finding the missing height measurement for her reduced tower? Her proportion does not have corresponding parts in the same position. For cross products, she needed to multiply 1050(328) and 5(x). She needed to divide both sides by 1640, instead of 1050. She needed to round down to 1.5 fee

Answers

Answer:

Her proportion does not have corresponding parts in the same position.

Step-by-step explanation:

Sharon is drawing up a plan for building a reduced Eiffel Tower on her backyard patio. She has room to make a base of 5 feet. Her work is shown below.

What was Sharon’s error in finding the missing height measurement for her reduced tower?

Her proportion does not have corresponding parts in the same position.

For cross products, she needed to multiply 1050(328) and 5(x).

She needed to divide both sides by 1640, instead of 1050.

She needed to round down to 1.5 feet.

Height : base = 1,050 : 328

She has room to make a base of 5 feet.

Height : base = x : 5

1,050 : 328 = x : 5

1,050 / 328 = x / 5

Cross product

1,050 * 5 = 328 * x

5,250 = 328x

Divide both sides by 328

x = 5250 / 328

= 16.006

Approximately 16

Sharon's error:

Her proportion does not have corresponding parts in the same position.

Write the equation of the line that has y-intercept of 4 and goes through the points (0,4) & (2.0) (Hint: use those points
to calculate slope first and write answer using y = mx + b)

Answers

Answer:

y = -2x + 4

Step-by-step explanation:

Let the equation of the line is,

y = mx + b

Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

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

Slope of a line passing through (0, 4) and (2, 0) will be,

m = [tex]\frac{4-0}{0-2}[/tex]

   = -2

Y-intercept of the line 'b' = 4

Therefore, equation of the line will be,

y = -2x + 4

JKLM is a cyclic quadrilateral.

Opposite angles of a cyclic quadrilateral are supplementary.

Therefore,

x + 104° = 180°

x = 180° - 104°

[tex] \huge \red {\boxed {x = 76\degree}} [/tex]

y + 52° = 180°

y = 180° - 52°

[tex] \huge \purple {\boxed {y = 128\degree}} [/tex]

By inscribed angle theorem:

[tex] 88\degree + z = 2\times 52\degree \\\\

88\degree + z = 104\degree \\\\

z = 104\degree - 88\degree \\\\

the number of girls on the school's basketball team decreased by 20% this year. if there were 25 girls on the team last year. how many girls are on the team this year

Answers

Answer:

Step-by-step explanation:

okay so to get 10% of 20 you just move the decimal to the right one so 25.0 would become 2.5 then to find 20% of that you multiply by 2 so 2.5 x 2 = 5 so that means the team lost 5 girls. 25-5=20 therefor there are 20 players on the team this year

For the sequence of numbers

Work out the position to term rule

22, 23, 24, 25, .......

Answers

Answer:

The term rule will be:

[tex]a_n=n+21[/tex]

Step-by-step explanation:

Given the sequence

[tex]22, 23, 24, 25, ...[/tex]

Computing the common difference of all the adjacent terms

[tex]22,\:23,\:24,\:25[/tex]

[tex]23-22=1,\:\quad \:24-23=1,\:\quad \:25-24=1[/tex]

As the difference between all the adjacent terms is the same and equal to

[tex]d=1[/tex]

The first element of the sequence

[tex]a_1=22[/tex]

We know that  An Arithmetic sequence has a constant difference 'd' and is defined by

[tex]a_n=a_1+\left(n-1\right)d[/tex]

substituting [tex]a_1=22[/tex], and [tex]d=1[/tex] in the nth term to get the term rule

[tex]a_n=a_1+\left(n-1\right)d[/tex]

[tex]a_n=\left(n-1\right)+22[/tex]

[tex]a_n=n+21[/tex]

Therefore, the term rule will be:

[tex]a_n=n+21[/tex]
