Compare 1 out of 3 and 3 out of 10. Are these values equal? Explain your reasoning.
1. Beginning with the equation x= -18, write the new equation produced by dividing both sides by $3.

Order this starting from the smallest:15.249 15.3 15.05 15.009 15.25

Answers

i think it might be easier to understand if i change decimals to fractions, so lets start ;)
$15.249=15(249)/(1000)$
$15.3=15.300=15(300)/(1000)$
$15.05=15.050=15(50)/(1000)$
$15.009=15(9)/(1000)$
$15.25=15.250=15(250)/(1000)$

denominators are the same so now you only have to compare numerators (biger numerator = greater fraction)

so:

$15(9)/(1000)<15(50)/(1000)<15(249)/(1000)<15(250)/(1000)<15(300)/(1000)$

it means that:

$15.009<15.05<15.249<15.25<5.3$

15.009
15.05
15.249
15.25
15.3

The circumference of a circle is C centimeters. The diameter of the circle is 13 centimeters.Which expression best represents the value of π?
A) C/6.5
B) 6.5/C
C) C/13
D) 13/C

Answers

Answer:

C) C/13

Step-by-step explanation:

The circumference of a circle is given by the formula

C = pi * d where c = circumference and d is the diameter

The diameter is 13

C = pi *13

Divide each side by 13

C/13 = d

The diameter is C/13

Circumference of the circle is the length of the boundary of the circle. The expression best represents the value of pi is C/13.

Given-

The circumference of the given circle is C centimetres.

Diameter of the given circle is 13 centimetres.

Circumference of the circle

Circumference of the circle is the length of the boundary of the circle.

We know that the circumference of the circle is given by,

$P=2\pi r$

Here r is the radius of the circle. Radius is the twice the diameter of the circle of the circle. That is,

$d=2r$

$r=(d)/(2)$

put the value in the parameter of the circle we get.

$P=2\pi *(d)/(2)$

$p=\pi d$

The value of circumference is C cm and diameter is 13 cm. Put these values to solve it further,

$C=\pi * 13$

Rewrite the equation for the pi, we get,

$\pi =(C)/(13)$

Hence, the expression best represents the value of pi is C/13.

The rectangles are similar.What scale factor was applied to the first rectangle to get the resulting image?

Enter your answer as a decimal in the box.

The image is a rectangle that says 6 then a smaller rectangle that says 1.5

Answers

the answer is .25 hope that helps

Answer:

The answer is 0.25! :)

Step-by-step explanation:

To find the scale factor, you have to do division of the shorter sides of the first and second rectangle. 1.5/6 which equals 0.25.

Hope this helps! <3

Perry surveyed 60 students at her school and found that 0.45 of the students she surveyed said their favorite class is math. Another 35% of the students she surveyed reported that their favorite class is science. How many more students in the survey prefer math over science?

Answers

1. Perry surveyed 60 students at her school.
=> 0.45 of the students said that their favorite subject is math
=> 0.45 x 100 = 45%
Thus, 45 % of 60:
=> 60 * .45 = 27
35% of the student said their favorite is science:
=> 35% / 100 = 0.35
=> 35% 0f 60 equals:
=> 60 * .35 = 21
Thus, 27 – 21 = 6 of the student said that they love math over science.

Its d 6

10-12(1-x)=8(-12+6x)-14Please I need this ASAP and I need to know how to do the steps so I get it better.Please and thanks!

Answers

Answer:

1. Simply the left hand side by first multiplying the -12 with the (1-x) to get -12+12x since negative×negative will give you positive. So after the simplification on the left hand side you will get the expression 10-12+12x. Which will give you -2+12x on the left hand side.

2. You do same on the right hand side of the expression 8(-12+6x) -14. So you multiply the 8 with the expression in the bracket ONLY (-12+6x) then afterwards,you add the -14 it to get -96+48x-14 =-110+48x .NOTE. ADDING TO NEGATIVE NUMBERS GIVES YOU A NEGATIVE ANSWER. so -96+(-14)=-110. So after simplification. You will also get the expression-110+48x on the right hand side .

3. Then combining the two sides of the equation, the whole expression becomes

-2+12x = -110+48x. Then you group like terms by sending all number attached with a variable to the right hand side and non attached variable numbers to the left , given you

-2+110 = 48x-12x . NB .WHEN A POSITIVE NUMBER CROSSES THE EQUAL SIGN IT CHANGES TO NEGATIVE AND VICE VERSA.

4. -2+110 = 108 and 48x -12x =36x

So the final expression becomes 108= 36x

Then you divide both side by 36 ,thus 108÷36=36x÷36

Given you x= 3 as your final answer of the expression, since 108÷ 36= 3. And 36x÷36= x
