Answer:

38 : 133 and 16 : 56 are equivalent

Step-by-step explanation:

Given

1) [tex]38 : 133[/tex] and [tex]16 : 56[/tex]

2) [tex]15 : 20[/tex] and [tex]28 : 56[/tex]

Required

Determine which is equivalent

1) [tex]38 : 133[/tex] and [tex]16 : 56[/tex]

[tex]Ratio = 38 : 133[/tex]

Divide by 19

[tex]Ratio = 2:7[/tex] --- can't be further simplified

[tex]Ratio = 16 : 56[/tex]

Divide by 8

[tex]Ratio = 2:7[/tex]

Hence:

[tex]38 : 133[/tex] and [tex]16 : 56[/tex] are equivalent

2) [tex]15 : 20[/tex] and [tex]28 : 56[/tex]

[tex]Ratio = 15 : 20[/tex]

Divide by 5

[tex]Ratio = 3 : 4[/tex]

[tex]Ratio = 28 : 56[/tex]

Divide by 28

[tex]Ratio = 1:2[/tex]

Hence, both are not equivalent.

B. 12.25

Step-by-step explanation:

A=bxh=3.5·3.5=12.25

Answer:

17.15

Step-by-step explanation:

There are 2 ways to solve this.

One way is this:

Add 1.4 and 3.5 together to get the total length of the parallelogram. The sum would be 4.9. Then multiply this number by the height of the figure(3.5cm). So that the product of 4.9 and 3.5 is 17.15.

The second way is this:

Find the area of the two triangles and the square and then add those products together. So add:

So solve this equation and you will get:

The figure of y = x will be a straight line with slope 1 and they ;lie in the first quadrant and the third quadrant.

A linear function can be defined as the function whose graph is a straight line. It can also be defined as the function with one or more variables but does not have exponents to the variables or the exponent of the variable is 1.

We have to choose 5 ordered pairs first whose first and second coordinate are equal.

Let the coordinates be (-4, -4), (-2, -2), (0, 0), (2, 2) and (4, 4).

The ordered pairs are of the form (x, x), that both the coordinates have same value.

So we get a linear function y = x

The graph of a linear function will be a straight line.

Since y = x, the graph will be a straight line which tends to the positive direction and the slope of the line = 1.

That is , the angle that the line making with the X axis is 45°.

And the figure lies on first and third quadrant.

Hence the figure of y = x would be a straight line with slope 1.

Answer:

D

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

1) know your grams and centigrams!

     1 Grams = 100 Centigrams

2)  If you want to find the centigrams, all you gotta do is; multiply the gram to 100.

For example: This bar of chocolate has 100 grams of sugar. I wonder what is the mass in centigrams?

100 grams * 100 centigrams = 1,000 Centigrams.

3) To answer your question; multiply 347 by 100!

   347 * 100 = 34,700 centigrams.

16. 9 - (-5) = 21.9

17. -12 - ( + 8) = -4

18. 15 - 9 = 6

19. -5 - (-8)= 3

20. -11 - ( + 14 ) =​ -25

Step-by-step explanation:

Subtracting a negative from another number is the same as adding the number.  Thus, 16.9 - (-5) = 16.9 + 5.

Hope it helps <3 :)

Answer:

16.9-(-5)=21.9

17.-12-(+8)= -3

18.15-9=9.15

19.-5-(-8)=22

Answer:

40 and 10

Step-by-step explanation:

1. if the length is 'l' and height is 'h', then according to the condition 1/4*l=h.

2. if the given area is 400, it means, h*l=400;

3. if to substitute h=1/4*l into the formula of the area, then

l*l*1/4=400; ⇔ 1/4*l²=400;

4. if to calculate the value of the 'l', then l=40 (the required length).

5. if to substitute l=40 into 1/4*l=h, then h=10 (the required height).

Answer:

$12,000.

Step-by-step explanation:

Given that in the year 2001, a person bought a new car for $ 15500, and for each consecutive year after that, the value of the car depreciated by 5%, to determine how much would the car be worth in the year 2005, to the nearest hundred dollars, the following calculation must be performed:

100-5 = 95

15,500 x 0.95 x 0.95 x 0.95 x 0.95 x 0.95 = X

14.725 x 0.95 x 0.95 x 0.95 x 0.95 = X

13,988.75 x 0.95 x 0.95 x 0.95 = X

13,289.3125 x 0.95 x 0.95 = X

12,624.846875 x 0.95 = X

11.993.60453125 = X

Thus, to the nearest hundred dollars, the cost of the car after 5 years will be $ 12,000.
