110º
Step-by-step explanatio:
6x+20 + 4x+10 = 180
180 - 30= 150
150=10x
10x/150
x = 15
6(15) + 20 = 110
A meat-seller sells x kg of ducks at $8.50 per kg and (2x + 5 ) kg of chicken at $3.60 per kg. If he collects a total of $206.40, find the value of x.
Answer:
[tex]x = 12[/tex]
Step-by-step explanation:
1) Set up an equation that involves all of the values; the price and kg of each duck and chicken equating to 206.40.
[tex]8.50(x) + 3.60(2x + 5) = 206.40[/tex]
[tex]8.50x + 7.2x + 18 = 206.40[/tex]
2) Solve it.
[tex]15.7x + 18 = 206.40[/tex]
[tex]15.7x = 206.40 - 18[/tex]
[tex]15.7x = 188.4[/tex]
[tex]x = \frac{188.4}{15.7}[/tex]
[tex]x = 12[/tex]
The time t required to empty a water tank varies inversely as the rate of pumping p. A pump can empty a water tank in 40 min at the rate of 120 gal/min. Write the equation of the inverse variation. How long it will take the pump to empty the water tank at the rate of 200 gal/min?
the question requires:
the time t required.
the equation of the inverse variation.
how do find t:
first we determine how much the tank holds by multiplying 120 by 40.
the tank holds 4800 gallons.
so now to find t we can use the formula v = d/t where d is the 4800 gallons.
so: t = d/v
t = 24 minutes
now for the equation of the inverse variation.
we can say that the equation is t = d/v since t and v are inversely proportional.
note that v and t stand for velocity and time respectively.
make sure to ask if you need any further guidance!!

Answer:
32
Step-by-step explanation:
Triangle angle = 180
First we add!
58 + 90 + c = 180
148 + c = 180
Now we subtract!
180 - 148 = c
32 = c

There are 3 children of a lady. In how many ways is it possible to dress them for a party if the first child likes 3 dresses, second likes 4 and the third likes 5 but the third child has out grown one of them? Each child has a different set of clothes.
A. 11
B. 10
C. 60
D. 48
E. 15
ty!
If all of their dresses are fit for the kids, the possible way to dress them is 3*4*5=60
But one dress is out grown for the third child. Hence, the combination that are not possible.
3*4*1=12
So total number of possible ways are :
3*4*5 - 3*4*1=48
Hence the answer is option D.

Step-by-step explanation:
Secant and tangent line from a point outside the cirlcle,
(length of th tangent)² = length of the secant * external segment
26² = (13 + x) * 13
[tex]\sf (13 +x)*13 = 26 *26\\[/tex]
[tex]\sf 13 + x =\dfrac{26*26}{13}[/tex]

x = 52 - 13
x = 39

Find the area
Answer:
18.8
Step-by-step explanation:
First find the area of the rectangle, which is 4x3 (base x height) the area of the rectangle is 12.
We are given the radius as 2 for the quarter circles, and 2 quarter circles form 1 semicircle, so really we can solve for the area of one semi circle using the formula ( (pi*radius²)/2 ). Plug in the values and you should get 6.28.
Next, you add the area of the figures so 12+6.8 which is equal to 18.8.

Answer:
45.2pi inches
Step-by-step explanation:
C=2×pi×r
since the answers already have pi we don't need to multiply it
C=2×22.6 = 45.2pi inches
Answer:
A. 22.6π
Step-by-step explanation:
Given:
22.6 inches across = diameter
What we need to find is how much ribbon do we need, so we use the formula:
C = 2πr
C = Circumference
r = radius = half diameter
Since we know the diameter, we do half of it to get the radius
22.6 ÷ 2 = 11.3
radius = 11
Now we substitute this into the formula:
C = 2πr
Substitute radius into formula
C = 2π(11.3)
Multiply 2 and 11.3
C = 22.6π

Answer:
we can't really answer the question without the pictue, but if the time count stays the say and the distance doen't, it would be (t=time/d=distance) (lets say time was an hour and you traveled 11 miles each hour,) then it would be 11t = d

Latonya was just hired as an engineer for an electric company. she will make a salary of $50,000 a year. how much of latonya's salary will be taxed at the 10 percent rate? how much of latonya's salary will be taxed at the 28 percent rate?
The $5000 will be taxable amount at 10% of Latonya's salary, and $14000 will be taxable amount at 28% of Latonya's salary.
What is the income tax rate?It is defined as the tax rate applied on the solely earned money by a single entity.
Latonya salary per year = $50,000
If Latonya's salary will be taxed at the 10% rate, then she needs to pay tax:
[tex]= $50,000\times10\%[/tex]
[tex]=50000\times \frac{10}{100}[/tex]
[tex]= \$ 5000[/tex]
If Latonya's salary will be taxed at the 28% rate, then she needs to pay tax:
[tex]= \$50,000\times28\%[/tex]
[tex]=50000\times \frac{28}{100}[/tex]
[tex]= \$14000[/tex]
Thus, the $5000 will be taxable amount at 10% of Latonya's salary, and $14000 will be taxable amount at 28% of Latonya's salary.

Answer:
C $56,508
Step-by-step explanation:
You take the property taxes of $3164.45 & divide by the tax rate of .056 & you get $56,508
To double check, $56,508 property value X the tax rate of .056 (5.6%) = $3,164.45
A right pyramid with a square base is shown. the length of the base is 8 inches and the slant height is 5 inches. kabir wants to know the volume of a solid right pyramid with a square base. he uses a ruler to measure the length of the base as 8 inches. he then measures the slant height to be 5 inches. the hypotenuse of the right triangle used to determine the height is inches. the leg of the right triangle that lies on the same plane as the base is inches. the height of the pyramid is inches. the volume of the solid pyramid is cubic inches.
The volume of the given pyramid comes to be 64 cubic inches.
Length of the square base a= 8 inches
Slant height l =5 inches
What is the volume of a pyramid?The volume of a pyramid is with base area A and height h is 1/3Ah.
So, base area A= 8*8 =64 square inches.
From Pythagoras theorem
[tex]l^{2} =(\frac{a}{2})^2 +h^{2}[/tex]
[tex]5^{2} =(\frac{8}{2})^2+h^{2}[/tex]
[tex]h=3[/tex] inches
So, volume of the pyramid = 1/3*A*h
=1/3*64*3
=64 cubic inches.
Hence, the volume of the given pyramid comes to be 64 cubic inches.

If 1/3 gallon of paint covers 1/6 of a wall, then how many quarts of paint are needed for the entire wall?
Answer:
8 quarts
Step-by-step explanation:
1/3 of a gallon ---1/6 of a wall
x - 1 (all the wall)
x = (1 x 1/3) / 1/6
x = 1/3 / 1/6
x = 6/3
x = 2 gallons
1 gallons - 4 quarts
2 gallons - x
x = (2 x 4) / 1
x = 8 / 1
x = 8 quarts
