When Sandy and Allen's mother decorates the house for a holiday by herself, it takes her 5 hours. When both Sandy and Allen help, the three can finish the job in 2.5 hours. When only Allen helps his mother decorate, it takes the two 3.5 hours. How long would it take Sandy to decorate the house by herself?
Answer:
8 3/4
Step-by-step explanation:
time for all work:
Mother - 5 hours
Mother + Sandy + Allen - 2.5 hours
Mother + Allen - 3.5 hours
Sandy - x
In 1 hour
Mother - 1/5
Mother + Sandy + Allen - 2/5
Mother + Allen - 2/7
Sandy - 1/x
(M+S+A) - S = (M+A)
2/5 - 1/x = 2/7
solve equation
x = 8 3/4 hours
Hope this helps :)
The number of hours that Sandy took to decorate the house by herself will be 8.75 hours.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
At the point when Sandy and Allen's mom designs the house for a vacation without help from anyone else, it requires her 5 hours. At the point when both Sandy and Allen help, the three can complete the task in 2.5 hours. At the point when just Allen assists his mom with finishing, it requires two 3.5 hours.
Let 'M', 'S', and 'A' be the number of hours of mother, Sandy, and Allen. Then the equations are given as,
M = 5 ...1
1/M + 1/S + 1/A = 1/2.5 ...2
1/M + 1/A = 1/3.5 ....3
From equations 2 and 3, then we have
1/3.5 + 1/S = 1/2.5
1/S = 1/2.5 - 1/3.5
1/S = 4 / 35
S = 35/ 4
S = 8.75 hours
The number of hours that Sandy took to decorate the house by herself will be 8.75 hours.

Given: ΔABC, AB=12, m∠A=60°,m∠C=45°, AB =8 Find the perimeter of ΔABC
Answer:
The perimeter of ΔABC is 43 units
Step-by-step explanation:
An illustrative diagram is shown in the attachment below.
To find the perimeter of the triangle, we will first determine the length of the unknown sides.
First, we can determine /BC/ using the Sine rule
From Sine rule
[tex]\frac{SinA}{a} = \frac{SinB}{b} = \frac{SinC}{c}[/tex]
∴ [tex]\frac{SinA}{a} = \frac{SinC}{c}[/tex]
In the diagram, [tex]a = /BC/[/tex] and [tex]c = /AB/ = 12[/tex]
m∠A=60° and m∠C=45°
∴ [tex]\frac{Sin60}{/BC/} = \frac{Sin45}{12}[/tex]
[tex]/BC/ = \frac{12 \times Sin60}{Sin45}[/tex]
[tex]/BC/ = 6\sqrt{6}[/tex]
To find /AC/, will first determine m∠B
m∠A + m∠B + m∠C = 180° (Sum of angles in a triangle)
60° +m∠B + 45° = 180°
m∠B + 105° = 180°
m∠B = 180° - 105°
m∠B = 75°
Also, using the sine rule
[tex]\frac{SinB}{b} = \frac{SinC}{c}[/tex]
From the diagram, [tex]b = /AC/[/tex]
[tex]\frac{Sin75}{/AC/} = \frac{Sin45}{12}[/tex]
[tex]/AC/ = \frac{12 \times Sin75}{Sin45}[/tex]
[tex]/AC/ = 6 + 6\sqrt{3}[/tex]
Now,
The perimeter of ΔABC = /AB/ + /BC/ + /AC/
= [tex]12 + 6\sqrt{6} + 6+6\sqrt{3}[/tex]
= 43.09 units
≅ 43 units
Hence, the perimeter of ΔABC is 43 units.
Answer:
Using the figure above, if AB = RT and ∠R = 70°, then ________.
ΔABC ~ ΔRTS
m ∠ S = 50°
ΔABC ≅ ΔRTS
m ∠ S = 60°

7-6=1 but instead of putting the one there it would just be x depending on your teacher they'd mark it wrong if you put the 1.
x+6=20 so what must X represent to get blank plus 6=20??
Answer:
14
Step-by-step explanation:
20-6=14
x=14
hi ! x must represent 14 in order for x+6 = 20
if we insert the x which would be 14 it would be 14+6=20 :))

a. 110 mi
2 h
b. 265 mi
6 h
c. 385 mi
7
h
d. 550mi
10 h
Answer:
265 miles per 6 hours
Step-by-step explanation:
Multiply 55 by 1, 2, 3, 4, 5 and so on, to get the speed per each of those hours.
55 x 2 = 110 miles per 2 hours
55 x 6 = 330 miles per 6 hours
55 x 7 = 385 miles per 7 hours
55 x 10 = 550 miles per 10 hours.
Answer choice b (265 miles per 6 hours) is not equivalent to 55mph.

A company makes plastic beach balls with a radius of 2 inches. How many square inches of plastic does the company
need to make 10 beach balls? Use 3.14 for x and round to the nearest tenth.
Recall the formula SA - 48/?.
50.24 in 2
100.5 in 2
2512 in 2
5024 in 2
Answer:
502.4 in²
Step-by-step explanation:
Area of a sphere = 4 πr²
Plastic beach balls are spherical in shape.
Hence, the Area of a sphere = 4πr²
Where r = radius = 2 inches
π = 3.14
Hence, the area of one spherical ball =
4 × 3.14 × 2²
= 50.24 square Inches
For 1 spherical ball, 50.24 square inches of plastic is needed to make it.
How many square inches of plastic does the company need to make 10 beach balls?
Therefore,
1 spherical ball = 50.24 in²
10 spherical balls = x
Cross Multiply
x = 10 × 50.24 in²
x = 502.4 in²
Therefore, 502.4 square inches of plastic is needed by the company to make 10 beach balls.

Answer:The answer is 14x-25=115 (B)
Step-by-step explanation:
he bought a certain amount of shirts, each being 14 dollars. So 14(how ever many shirts)- 25(the coupon) = Sales price
Answer:
b. 14x-25=115
Step-by-step explanation:
14 dollars each and 25 discount
the "each" here means the cost per cloth is 14, and total cost of the clothes Marco buy will increase depend on the amount of clothes.
Thus, it is 14x
The 25 discount represent that NO MATTER how many clothes Marco purchase, he only gets a discount of 25. It is a independent value.
Total clothes bought - discount = total amount of money spent.
Thus, it is 14x-25=115

your answer as a decimal number or an equation.
(1,6) (-5,-7)
Answer:C. 13/6
Step-by-step explanation:
The slope is always rise over run. So when going from the coordinate (-5,-7) to the coordinate (1,6) we go up 13 then go to the right 6. And since we went up and to the right it is a positive slope.
