Answer:

Scale Factor = 2

Reason:

Since, B is a scaled copy of A it's corresponding sides must be in proportion with that of A, and that proportion would be its scale factor.

I held their horizontal sides and compared them.

in case of A, the side is 2.5 and in case of B it's 5.

so, 5 divided by 2.5 gets you 2, that is the scale factor.

3, 5 (from left to right)

Solution:

[tex] \boxed{ \mathsf{ \frac{crsp. \: side \: of \: b}{crsp. \: side \: of \: a} = scale \: factor }}[/tex]

this also means

[tex] \boxed{ \mathfrak{crsp. \: side \: of \: b =( scale \: factor) \times \: crsp. \: side \: of \: a }}[/tex]

Scale factor = 2

Using this we'll get the answer to the question marks

The corresponding side to 1.5 is the vertical one in B.

=> corresponding side in B = 2 × 1.5

= 3

(this is the first question mark in order from left to right)

The corresponding side to 2.5 is:

= 2 × 2.5

= 5

53° and 37° (from top to bottom)

Solution:

Scaled shapes have the same angle measures.

Reason:

When we scale two line segments meeting at a point, the lengths of the segments change but they still are part of the same pair of rays making the same angle.

an online article suggested for each additional person who took up regular running for exercise the number of cigarette smoke daily woo decrease by 0.178 if we assume that 45 minute cigarettes will be smoked per day if nobody ran what is the equation of regression line for predicting number cigarette smoke per day in the number of people who regularly run for exercise

Answers

The linear function that models the situation is given by:

[tex]y = 45 - 0.178x[/tex]

The format of a linear function is:

[tex]y = mx + b[/tex]

In which:

m is the slope, which is the rate of change.b is the y-intercept, which is the initial value.

If nobody ran, 45 cigarettes would be smoked, thus the initial value is of [tex]b = 45[/tex].For each additional person that exercises, the amount decays by 0.178, thus the slope is [tex]m = 0.178[/tex].

The equation that models this situation is:

[tex]y = 45 - 0.178x[/tex]

A similar problem is given at https://brainly.com/question/16302622

Who can answer this?

Answers

Answer:

because of parallel lines it's 63

Given that < h (interior) and < k (exterior) are on the same side of the transversal, they are corresponding angles with the same measure.

Given that m < k = 63°, then m < h must also be 63°.

Therefore, the correct answer is 63°.

At a bargain store beast boy bought 5 items that each cost the same amount. Cyborg bought 8 items that each cost the same amount, but each was $1.50 less than the items beast boy bought. Both beast boy and Cyborg paid the same amount of money. What was the individual cost of each person's items?

C: Check your solution. Show your work
D: What was the individual cost of each person's items? State the solution in complete sentences.

Answers

Answer:Bb 12. Cyborg 12

Step-by-step explanation:

Right for my test

The required number of items purchased by the beast boy is 4 and by Cyborg is 2.5.

Given that,
At a bargain store beast boy bought 5 items that each cost the same amount. Cyborg bought 8 items that each cost the same amount, but each was $1.50 less than the items beast boy bought. Both beast boy and Cyborg paid the same amount of money.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Let the cost of the item bought by the beast boy is x, and the item bought by the Cyborg be y,
According to the question,
5x = 8y
x = 8/5y - - - - - - -(1)
y = x - 1.50 - - - - - -(2)
Substitute the value of equation 1 to equation 2
y = 8/5y - 1.50
5y = 8y - 7.50
7.50 = 3y
y = 2.5
Now, put y in equation 1
x = 8 / 5 × 2.5
x = 8 × 0.5
x = 4
Now, the costs,
5x = 4 × 5 = $20
8y = 8 × 2.5 = $20

Thus, the required number of items purchased by the beast boy is 4 and by Cyborg is 2.5.

Write the equation of the line in fully simplified slope Intercept form.

Answers

Answer:

y = -0.83x - 2

Step-by-step explanation:

Slope intercept form is y = mx+b.

M is the slope: In this case the slope (rise/run) is 10/12. However, the slope is decreasing is that would make it negative.

Now we have: y = -0.83x + b

B represents the y-intercept. The y-intercept here is -2. So our final equation is:

y = -0.83x - 2

What is a two-way frequency table?

A two-way frequency table is a way of organizing and displaying data that shows the frequency of occurrences of two categorical variables.

In such a table, the rows represent one variable, the columns represent the other variable, and the cells show the number (or frequency) of times that each combination of categories occurs.

We have,

A two-way frequency table shows how many times each combination of two categorical variables occurs.

In the table, the rows represent the "play an instrument" variable, the columns represent the "are in band" variable, and the totals are shown at the end of each row and column.

The entries in the table represent the frequency, or the number of students who belong to each combination of categories.

In this case, the two variables are "play an instrument" and "are in band". Based on the given information, we can create the following table:

Thus,

If sin x=0.96, find tan x

Answers

Step-by-step explanation:

sin x= P/H

sin x = 0.96 = 96/100 = 24/25.

Let the ratio of the sides be x.

B²=H²-P²

B²=(25x)²-(24x)²

B²=625x²-576x²

B²=49x²

B=√49x²

B= 7x.

cos x = 7x/25x = 7/25.

therefore, tan x = sin x / cos x = (24/25)/(7/25) = 24/25×25/7 = 24/7 .
