A rectangle has a width of x and a length of
x + 2. The perimeter is 20 inches. Find the value of the width and the length of the rectangle.
A. Width=9, Length=11
B. Width=6, Length=8
C. Width=4,Length=6
D. Width=3, Length=5
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

this situation and then solve.
Answer:
i don't know what the equation would be but hope this helped! 1.72 for each pencil
Step-by-step explanation:
9 - 3.85 = 5.15
5.15/3 = 1.72 for each pencil
Answer:
About $1.72 per pencil
Step-by-step explanation:
1. 9-3.85 = 5.15
2. 5.15/3 = 1.71 2/3 (1.7166666667)

t/3-1/2=t+3/9
Answer:
-1.25
Step-by-step explanation:
t÷3-1÷2 = t÷1+3÷9
2t-3÷6 = 9t+3=9
18t - 27 = 54 + 18
18t -54t = 18 + 27
-36t = 45
Divide through by -36
t = -1.25

State what additional information is required in order to know that the triangles are congruent
for the reason given.
Only for 5 and 6
Answer:
Step-by-step explanation:
5). Reason for the congruence is given as SSS.
"Property SSS for the congruence of two triangles states that all three sides of the triangles must be congruent."
In the given triangles ΔMLN and ΔULN,
ML ≅ LU [given]
NL ≅ NL [Reflexive property]
To fulfill SSS property third sides of the given triangles should be given as congruent.
Therefore, additional information required will be MN ≅ NU
6). SAS property of congruence states that "two sides and included angle between these sides of two triangles must be congruent"
From the given triangles ΔPWS and ΔVXW,
PW ≅ VW [Given]
∠PWS ≅ ∠XWV [Vertically opposite angles]
Therefore, to fulfill the property of SAS additional information required will be,
SW ≅ WV

13 cm
13.188 cm
13.19 cm
13.20 cm
Answer:
13.19
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
Using significant digits, the number becomes 13.19 cm

ZWXY is a right angle, find each measure.

mZWXZ =
mZZXY =
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°
The race course is 3/4 of a mile long. How many feet long is the race course?
Answer:
3960 feet
Step-by-step explanation:
Answer:
3,960 feet long
Step-by-step explanation:
1 mile = 5,280 feet
5,280 feet ÷ 4 (because the denominator is 4) = 1,320 feet
1,320 x 3 (the numerator is 3) = 3,960 feet
3/4 of a mile = 3,960 feet

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
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°.

Given that,
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]
