Next time include the entire question please; we're guessing here.

XZA and ZXL are alternate interior angles assuming we're told XL and AZ are parallel. Alternate means on opposite sides of the transversal; interior means between the parallel lines.

If that 123 degrees is indicating angle ZXL it also is the value for angle XZA because alternate interior angles are congruent.

Answer: angle XZA = 123°

Answer:

Please check the explanation.

Step-by-step explanation:

We know the equation

y = kx

k = y/x

where k is the proportionality constant

so,

First ratio can be calculated as

Miles = 45

Hours = 3/4

The ratio = 45 / (3/4)

= (45 × 4) / 3

= 180/3

= 60

Thus, the proportionality constant = 60

Thus, the remaining ratios can be calculated as:

The Pair (135, Hours)

135/Hours = 60

Hours = 135 / 60

= 27/12

= 9/4

= 2.25

Thus, the pair is (135, 2.25)

The Pair (Miles, 3)

Miles/3 = 60

Miles = 60×3

= 180

The Pair (90, Hours)

90/Hours = 60

Hours = 90 / 60

= 3/2

= 1.5

Thus, the complete table:

Miles 45 135 180 90

Hours 3/4 9/4 3 3/2

Verification:

Miles / Hour = 45/(3/4) = 60

Miles / Hour = 135 / 2.25 = 60

Miles / Hour = 180 / 3 = 60

Miles / Hour = 90 / 1.5 = 60

The units for cubic centimeters can be written as _____. Check all that apply.

GarryVolchara [31]

The correct answers for this completion exercise are the option "B" and the option "C":

B. cm³
C. cc

This means that you can write the unit of volume (or capacity) cm³ as cc.

Therefore, cm³=cc

For example, you have:

a) 10 cm³=10 cc
b) 110 cc=110 cm³
c) 1 litre (l)=1000 cm³
d) 1 litre (l)=1000 cc

Evaluate 7j+5-8k when j=0.5 and k=0.25

notka56 [123]

Answer:

6.5

Step-by-step explanation:

$7j + 5 - 8k \\ = 7 \times 0.5 + 5 - 8 \times 0.25 \\ = 3.5 + 5 - 2.00 \\ = 8.5 - 2 \\ = 6.5 \\$
