Step-by-step explanation:
Last month, he sold 50 chickens and 30 ducks for $550. This month, he sold 44 chickens and 36 ducks for $532
Answer:
★ Given :
Cost of 50 chickens and 30 ducks = $ 550
Cost of 44 chickens and 36 ducks = $ 532
★ To find :
Cost of chicken and duck
★ Solution :
Assume :
Cost of chicken = x
Cost of duck = y
According to question :
50x + 30y = 550 ......(1)
44x + 36y = 532......(2)
1) - (2)
(50x + 30y) - (44x + 36y) = 550 - 532
50x + 30y - 44x - 36y = 18
6x - 6y = 18
6(x - y) = 18
x - y = 18/6
→ x - y = 3 ....(3)
In equation 1 ,
50 x + 30y = 550
taking 10 common
10(5x + 3y) = 550
5x + 3y = 550/10
5x + 3y = 55
by taking 3 common
3(5/3 x + y) = 55
by dividing 3 on both sides
5/3x + y = 55/3 .....(4)
(3) + (4)
x - y + 5/3 x + y = 3 + 55/3
x + 5/3 x = 64/3
8/3 x = 64/3
by multiplying 3 on both sides
8x = 64
x = 64/8
→ x = 8
→ Cost of chicken = $ 8 ..
by putting value of x in equation 3
x - y = 3
8 - y = 3
y = 8 - 3
→ y = 5
→ Cost of ducks = $5..

a width of 15 inches, what is its length
Answer:
It should be 25.
Step-by-step explanation:
one Triangle is 5 times the size of the other triangle
length of 5 x 5 = 25
width of 3 x 5 = 15
What is the length of the dotted line in the diagram below? Round to the nearest tenth.
Answer:
length of dotted diagonal line = 11
Step-by-step explanation:
Using the Pythagorean theorem:
length of rectangle² = 9² + 6² = 81 + 36 = 117
length of rectangle = √117 = 10.82
length of diagonal² = 2² + 10.82² = 4 + 117 = 121
length of diagonal = 11

All dimensions of a cylinder are multiplied by 1.5. Which statement is true?
A. The total surface area is multiplied by 3.375.
The volume is multiplied by 2.25.
B. The total surface area is multiplied by 2.25.
The volume is multiplied by 3.375.
C. The total surface area is multiplied by 3.
The volume is multiplied by 4.5.
D. The total surface area is multiplied by 4.5.
The volume is multiplied by 3.
Answer:
The true statement is;
B. The total surface area is multiplied by 2.25
The volume is multiplied by 3.375
Step-by-step explanation:
By scale drawing proportionality, we have;
The amount by which all the dimensions of the cylinder are multiplied to create an image of the cylinder = 1.5
∴ The scale factor between the original cylinder and the image of the cylinder, S.F. = 1.5
By rule, we have;
The area factor of the surface area = S.F.² = 1.5² = 2.25
Therefore;
The total surface area of the original cylinder is multiplied by 2.25 to get the total surface area of the image of the cylinder
By rule, we have;
The volume factor = S.F.³ = 1.5³ = 3.375
Therefore;
The volume of the original cylinder is multiplied by 3.375 to find the volume of the image of the cylinder.

An arborist examined trees in an orchard to see if they were infected with a virus. The arborist counted 7 infected trees and 43 healthy trees. What percentage of the trees in the orchard were infected?
Answer: Percentage of infected trees =2%
Step-by-step explanation:
Number of Infected trees =7
Number of healthy trees=43
Total number of trees in the orchard=43+7=50
Percentage of infected trees =Number of Infected trees/Total number of tress in the orchard x 100
7/50 x 100 =2%

Answer:
each apple is £ 1.80
Step-by-step explanation:
i first multiplied the cost for one pear by 7, to get how much money was spent on pears out of the 12.70.
Then i took the remaining money and divided it by 2 to get how much each apple costs.
Answer:
1.80
Step-by-step explanation:
1) Price of Pears
[tex]1.30 * 7 = 9.10[/tex] formating: 1.30*7 = 9.10
2) Price of Apples
[tex]12.70 - 9.10 = 3.60[/tex] formating: 12.70-9.10 = 3.60
3) Price of Apples/Kg
[tex]\frac{3.60}{2} = 1.80[/tex] formating: 3.60/2 = 1.80
Write the equation in point-slope form of the line that passes through the given point and has the given slope: (-2, -1); m=-3
Answer:
y+1=-3(x+2)
Step-by-step explanation:
point-slope form is the formula y-y1=m(x-x1), where (x1, y1) is a point and m is the slope
we are given a point (-2, -1) and a slope of -3
all we really need to do is substitute the given into the formula
remember: since the formula gives subtraction, we're going to be subtracting, even though we have negative numbers
substitute -2 as x, -1 as y and -3 as m
y--1=-3(x--2)
we can simplify this equation:
y+1=-3(x+2)
Hope this helps!
What is the angel of c??
Explain which properties you would use to fully expand (the problem in the screenshot)
Answer:
Firs property used : Quotient Property
[tex]log_b(\frac{X}{Y} ) = log_bX -log_bY[/tex]
[tex]log_b(\frac{\sqrt[3]{x} }{36y^2} ) = log_b(\sqrt[3]{x}) - log_b(36y^2)[/tex]
Second property used : Product Property
[tex]log_b(XY) = log_bX + log_b Y[/tex]
[tex]log_b(\sqrt[3]{x}) - log_b(36y^2) = (log_b(\sqrt[3]{x}) - [log_b36 + log_by^2)[/tex]
Third property used : Power Property
[tex]log_b \sqrt[n]{X} = log_b(X)^{\frac{1}{n}} = \frac{1}{n} log_b X[/tex]
[tex](log_b(\sqrt[3]{x}) - [log_b6^2 + log_by^2) = \frac{1}{3} log_bx - 2log_b 6 - 2log_by[/tex]
Fully expanded form:
[tex]log_b(\frac{\sqrt[3]{x} }{36y^2} ) = \frac{1}{3} log_b x-2log_b6-2log_by[/tex]
