Answer:

18

Step-by-step explanation:

90 degree angle so

90-54=36

36 / 2 = 18

scale factor = 1.25

30 : 24 = 1.25

or

35 : 28 = 1.25

The scale factor of this parallelogram is 5/4

In this question, we need to find the scale factor;

This is a factor to which a certain unit is multiplied or divided by. In this question, we have to find the scale factor first in order to know the missing side of the parallelogram.

[tex]\frac{30}{24} = \frac{5}{4}[/tex]

We have check for one side, let us find the other side and compare

[tex]\frac{35}{28}=\frac{5}{4}[/tex]

The scale factor of this parallelogram is 5/4

Answer:

x > -22/7

Step-by-step explanation:

Given inequality:

- 7x - 15 < 6

adding 15 to both sides:

==> -7x - 15 + 15 < 6 + 16

==> -7x < 22

dividing both sides by 7:

==> -x < 22/ 7

multiplying both sides by -1

(anytime you multiply the inequality by -1 you must flip the inequality sign– replace the "<" with ">")

==> x > -22/7

Answer:

The side lengths are 84, 63 and 28

Step-by-step explanation:

The shortest side of a triangle is 13 cm.

Let x be the longest side

y be the shortest side

z be the other side

x + y + z = 50 ...........(1)

x = y + 8 ...........(2)

z = y + 3 ............(3)

Replace x with y+8 in equation 1

Replace z with y + 3 in equation 1

To estimate the value for y,

(y+8) + y + (y+3) = 50

Simplifying the above equation, we get

3y + 11 = 50

3y = 50-11

3y = 39

y = 39/3

y = 13 cm

Therefore, the shortest side of a triangle is 13 cm.

Answer:

38.75

Step-by-step explanation:

62*5/8=38.75

Answer:

38 3/4

Step-by-step explanation:

5/8 of 62 = 5/8 x 62

               = (5 x 62) ÷ 8

               = 310 ÷ 8

               = 38 3/4

Answer:

Solution:

Here,the denominators are 3 and 8

We have,3×8=24 and 8×3=24.

Now,

[tex] \displaystyle{ \frac{2}{3} = \frac{2 \times 8}{3 \times 8} = \frac{16}{24} }[/tex]

[tex] \displaystyle \frac{4}{8} = \frac{4 \times 3}{8 \times 3} = \frac{12}{24} [/tex]

Since,16>12,

So,

[tex] \displaystyle \: \frac{16}{24} > \frac{12}{24} [/tex]

i.e.

[tex] \displaystyle \frac{2}{3} > \frac{4}{8} [/tex]

Method of cross product:

[tex] \displaystyle \: \frac{2}{3} \: or \: \frac{4}{8} [/tex]

[tex] \displaystyle2 \times 8 = 16 \: \: \: \: \: > \: \: \: \: \: 3 \times 4 = 12[/tex]

[tex]16 > 12[/tex]

[tex] \displaystyle \therefore \: \frac{2}{3} > \frac{4}{8} [/tex]

[tex] \displaystyle{Thus,the \: fraction \: \frac{2}{3} \: is \: greater \: than \: the \: fraction \: \frac{4}{8} . }[/tex]
