Answer 1

Answer:

The first one is 280       The second is all of the above

Step-by-step explanation:

2.   You first divide the larger group by the smaller group  to find the ratio

      700 ÷ 40 = 17.5

     Now you multiply the ammount of patients who responded with 8  when there were 40 asked, by the ammount you multiply 40 by to get to 700

     16 × 17.5 = 280

The amount of people expected to respond with 8 hours when there is a sample size of 700 is 280 people.

3.  All of these examples represent two sets of related data whose change is being compared over a set amount of time.

Formula:

C = 2πr

Note: π = 3.14(About)

-------------------------------------------------------------------------------------------------------------

[3] It given that the diameter is 16 ft.

Diameter - a straight line passing from side to side through the center of a body or figure

Radius - Half of Diameter

C = 3.14(16)

= 50.24 ft

-------------------------------------------------------------------------------------------------------------

[4] It given that the radius  is 7.5 in

Radius - a line segment extending from the center of a circle or sphere to the circumference or bounding surface.

C = 3.14(15)

= 47.1 in

-------------------------------------------------------------------------------------------------------------

[5] It given that the radius is 42 m

C = 3.14(84)

= 263.76 m

-------------------------------------------------------------------------------------------------------------

As Noted : π is approximately 3.14. Thus the answers are approximately

Step-by-step explanation:

I don't know how to explain it, but I hope I got it right and that it helped you.

[tex]-\frac{10}{3}=[/tex]Both option A and option B are equivalent to the given fraction [tex]\frac{-10}{3}[/tex]. Option A displays [tex]-\frac{10}{3}[/tex] , and option B displays [tex]-\frac{-10}{-3}[/tex]. Thus, they both are equal.

Negative fractions:

A fraction can be represented with a numerator and a denominator where they are any integers either negative or positive.

The equivalent fractions that can be written for negative fractions are as follows:

[tex]\frac{-a}{b} =\frac{a}{-b}=-\frac{a}{b}=-\frac{-a}{-b}[/tex]

The explanation for the given options:

Given fraction is [tex]\frac{-10}{3}[/tex]

Option A:

Here the fraction is [tex]-\frac{10}{3}[/tex]

minus, start function, 10 divided by 3, end function

Option B:

Here the fraction is [tex]-\frac{-10}{-3}[/tex]

minus, start the fraction, minus 10 divided by minus 3, end fraction

This is on simplifying equals to [tex]-\frac{10}{3}[/tex]

Therefore, option A and option B are equivalent fractions for the given fraction.

Answer:

C

Step-by-step explanation:

Let's say y=5

(5*40)+(5*8)

200+40=240

48*5=240

Option C. (y*40)+(y*8)

Option C is true because y*40 in the first parenthesis is equal to 40y, and y*8 in the second set of parenthesis is equal to 8y. When combined, the sum is 48y; therefore equivalent to the provided expression of y*48.

write the expression for when you translate the graph of y=|x+7| on unit to the left

Answers

Answer: y = |x+8|

Step-by-step explanation:

To shift the graph to either the left or right, you must change the expression inside the absolute value sign. To move the graph to the left, you must add to the inside of the absolute value sign, and to move to the right subtract from the inside of the sign. In this case, you will add 1 to |x+7| to shift to the left, so the answer should be y = |x+8|.

Answer:

y = |x+8|
