Answer:

x = 27

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the given angles and equate to 180

90 + x + 23 + x + 13 = 180, that is

126 + 2x = 180 ( subtract 126 from both sides )

2x = 54 ( divide both sides by 2 )

x = 27

The table represents an exponential function. A 2-column table has 4 rows. The first column is labeled x with entries 1, 2, 3, 4

Papessa [141]

Answer:

3/4

Step-by-step explanation:

x | y

1 | 3/2

2 | 9/8

3 | 27/32

4 | 81/128

$\frac{\frac{9}{8}}{\frac{3}{2}}=\frac{9}{8} \div \frac{3}{2}=\frac{9}{8} \cdot \frac{2}{3}=\frac{18}{24}=\frac{18 \div 3}{24 \div 3}=\frac{6}{8}=\frac{6 \div 2}{8 \div 2}=\frac{3}{4}$

So the multiplicative rate of change of this function is $\frac{3}{4}$ .

6. A Factory Has 1700 Workers. 640 Of The Workers Are Female.. 2/5 Of are under the age of 35.1/4 of the male workers are under

Lerok [7]

Answer:

521

Step-by-step explanation:

f = factory

fTotal = 1,700

female workers = 640

0.4 female workers are under 35

0.25 male workers are under 35

1,700 - 640 = 1,060

Male Workers = 1,060

0.4% of 640 = 256

0.2% of 1060 = 265

256 + 265 = 521

521 of workers are under the age of 35
