Please help me with this!!!

Mathematics
1 answer:
Nostrana [21]2 years ago
5 0

Answer:

Below in bold

Step-by-step explanation:

I AM ASSUMING that CDEF is a Rhombus.

If it is than triangle DEG is right-angled.

so 2x + 18 + 5x + 2 = 90.

7x = 90 - 20 = 70

x = 7.

So m < CDF  = 5x + 2

= 5(10) + 2

= 52 degrees.

m < DCE = 2(10) + 18 = 38 degrees.

The diagonal bisects < DCF so m < ECF = 38 degrees.

So m < DCF = 2 * 38 = 76 degrees.

Opposite angles of a rhombus are equal so m < DEF = 76 degrees.

23/147 yd × 3/14 after reducing them by a factor of 2/147 what are the original dimensions of the playground in yards? Write you
DENIUS [597]

Answer:

So the dimensions are 11 1/2 yds × 15 3/4 { 11 whole number 1 by 2 yards multiplied by 15 whole number 3 by 4}

Step-by-step explanation:

Here multiplicative property will be used .

a*<u>1/a</u>= 1

1* <u>a/1</u>= a   ( reciprocal)

23/147 yd × 3/14 will be multiplied with the reciprocal of the factor 2/147 to

get the original number.

23/147 yd*147/2 × 3/14*147/2

23/2 yds  × 441/28

11 1/2 yds × 15 3/4

So the dimensions are 11 1/2 yds × 15 3/4  11 whole number 1 by 2  multiplied by 15 whole number 3 by 4.

A cyclist accelerates at a rate of 7.0 m/s2. how long will it take the cyclist to reach a speed of 18 m/s?
mart [117]
At constant acceleration  the equation  is

v = u + at     where u = initial speed,  a = acceleration. t = time and v = final speed

So here we have  18 = 0 + 7t

t = 18/7  = 2.6 seconds ( to nearest tenth)
