Two supplementary angles. One angle is 25 more than the second angle, find the measure of the second angle. The measure of the second angle is

Answers

Answer:

  77.5°

Step-by-step explanation:

Let s represent the measure of the second angle. Then the first angle is s+25. These two angles are supplementary, so their sum is 180:

  (s+25) +s = 180

  2s = 155

  s = 77.5

The measure of the second angle is 77.5°.

2.Brian is heading out for a steady early morning jog as one of his training runs for a marathon. He plans to jog
18 miles. He covered the first 4 miles in 39 minutes. Keeping the same steady pace, which of the following
is closest to the time that it will take Brian to finish his jog from the 4-mile point?
(1) 2.3 hours
(3) 2.9 hours
(2) 2.5 hours
(4) 3.3 hours

Answers

It would be 2.9 hours because you would add 4 of the 39 minute intervals together and for the last interval if Brian ran extra 2 miles which would be 20 miles. You would have to divide the 39 minute interval by 2 since he ran an extra 2 miles to get 19.5 minutes for him to get his last 2 miles for his 18 mile jog. Then add the 4 intervals of 39 minutes along with the 19.5 minutes to get you a total of 175.5 minutes and if you were to convert that to hours and minutes it would be 2 hours and 55 1/2 minutes so technically it would be 2.9 hours. To find the 2.9 you would divided 175.5 by 60 since there is 60 minutes an hour to get the answer 2.925 unrounded, but rounded it would get you the final answer 2.9 hours.

Final answer: 2.9 hours.

Step-by-step explanation:

The sum total of 2.36 cm, 5.298 cm, and 5.53 cm, using significant digits is 13.19cm

The numbers in the question are decimals. Decimals are made up of writing integers and non integers. They are made up of tens, hundreds, tenths and hundredths.

For example, the decimal 2.36, is made up of unit (2), tenths (2) and hundredths (6).

In order to determine the sum of the decimals given, add 2.36, 5.298 and 5.53 together.

2.36 + 5.298  + 5.53 = 13.188 cm

Lisa Company uses the periodic inventory system to account for inventories.

Information related to Lisa Company's inventory at October 31 is given,

Suppose, find the value of ending inventory using the FIFO cost assumption if 500 units remains on hand at october 31

We need to calculate the value of ending inventory

Using FIFO method

[tex]value\ of\ ending\ inventory =305\ units\times\$10.6+195\ units\times\$11.60[/tex]

[tex]value\ of\ ending\ inventory = 3233+2262[/tex]

ZWXY is a right angle, find each measure.
W
Х
z
Y
mZWXZ =
mZZXY =

Answers

Answer:

m∠WXZ = 38°

m∠ZXY = 52°

Step-by-step explanation:

In the question

∠WXZ and ∠ZXY are two adjacent angles and formed together ∠WXYThat means the measure of ∠WXY equal the sum of measures of ∠WXZ and ∠ZXY

∵ ∠WXY is a right angle

→ That means its measure is 90°

m∠WXY = 90°

m∠WXZ + m∠ZXY = m∠WXY

∵ m∠WXZ = (5x + 3)°

∵ m∠ZXY = (8x - 4)°

∵ m∠WXY = 90°

→ Substitute their values in the equation above

(5x + 3) + (8x - 4) = 90

→ Add the like terms in the left side

∵ (5x + 8x) + (3 - 4) = 90

∴ 13x + (-1) = 90

∴ 13x - 1 = 90

→ Add 1 to both sides

∴ 13x - 1 + 1 = 90 + 1

∴ 13x = 91

→ Divide both sides by 13

∴ [tex]\frac{13x}{13}=\frac{91}{13}[/tex]

x = 7

→ To find the measure of each angle substitute x by 7 in their measures

∵ m∠WXZ = 5x + 3

∴ m∠WXZ = 5(7) + 3

∴ m∠WXZ = 35 + 3

m∠WXZ = 38°

∵ m∠ZXY = 8x - 4

∴ m∠ZXY = 8(7) - 4

∴ m∠ZXY = 56 - 4

m∠ZXY = 52°

A. Width=9, Length=11
B. Width=6, Length=8
C. Width=4,Length=6
D. Width=3, Length=5

Answers

Answer:

width= 4, length= 6

Step-by-step explanation:

use perimeter formula and substitute values

so formula becomes:

20= 2(x+2) + 2(x)

expand the brackets and that gives us

20= 2x+4 +2x

so

16=4x

x= 4

so width is x which is 4

and length is x+2 which is 6
