Answer:

A) 24 women

B) 52 men and women are at the meeting

Step-by-step explanation:

A)

Let y = women at the meeting

7:6 = 28:y

7/6 = 28/y

6×38 = 7y

6×28⁴/7¹ = 7y¹/7¹

y= 6×24

y=24

B)

Number of women at the meeting = 24

Number of men at the meeting = 28

Total number of people at the meeting = 24+28

= 52

The circumference of a standard bowling ball is about 27 in. To the nearest unit, how many square inches is the surface area of
Sidana [21]
The surface area of a sphere is S=4 \pi  r^{2} where r is the radius;
The circumference is 2 \pi r=27 in so that r= \frac{27}{2 \pi }=4.5 in using this value we can evaluate the surface area of 1 ball as:
S=4 \pi r^{2} =4 \pi  (4.5)^{2} =254.3  in^{2}
For 100 ball you get: 100*254.3=25430  in^{2}

Which expressions are equivalent to − 56 z + 28 −56z+28minus, 56, z, plus, 28? Choose 2 answers: Choose 2 answers: (Choice A) A
Dmitrij [34]

Answer:

(D)-2(28z-14) \: and\:\\(E) -7(8z-4)

Step-by-step explanation:

We are to determine which of these expressions are equivalent to: -56 z + 28

(A)\frac{1}{2}\cdot(-28z+14) \\(B)(-1.4z+0.7)40\\(C)(14-7z)\cdot(-4)\\(D)(8z-4)(-7)\\(E)-2(-28z-14)

-56 z + 28

  • If we factor out -2

-56 z + 28=-2(\frac{ -56 z}{-2} + \frac{28}{-2})=-2(28z-14)

  • If we factor out -7

-56 z + 28=-7(\frac{ -56 z}{-7} + \frac{28}{-7})=-7(8z-4)

Therefore, the two equivalent expressions are:

-2(28z-14) \: and\: -7(8z-4)

Find the sum of the sequence. 45+46+47+48+...+108
Anna11 [10]
We know, S = n/2 [ a + l ]
Here, a = 45
l = 108

Calculation of n:
a(n) = a + (n - 1)d
108 = 45 + (n - 1)1
108 - 45 = n - 1
63 + 1 = n
n = 64

Now, substitute in the expression:
S = 64/2 [ 45 + 108 ]
S = 32 [ 153 ]
S = 4896

In short, Your Answer would be 4896

Hope this helps!

Without calculating the answer for 5 1/5 * 2/5 be larger or smaller than 5 1/5​
solniwko [45]

Answer:

Hope this helps!

Branliest would be appreciated :DD
