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

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%

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)

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.

Step-by-step explanation:
2 x [(27–3) - (3+4)] = n
what’s (n)
Answer:
n = 34
Step-by-step explanation:
2{(24- ( 3 + 4)) =n
2{(24 - 7) =n
2 x 17 = n
34 = n
swap the sides
n = 34

Answer:
<1 = 112degrees
<2 = 33degrees
Step-by-step explanation:
From the figure, the sum of interior angles of the larger triangle is equal to the exterior, hence;
<1 + 15 = 127
<1 = 127 - 15
<1 = 112degrees
For the smaller triangle;
<1 = <2 + 79
112 = <2 + 79
<2 = 112-79
<2 = 33
Hence the measure of <2 is 33degrees
What’s the point of intersection line 1 is 3x-2y=5 and Line 2 is x+2y=7
Answer:
(3,2)
Step-by-step explanation:
3x-2y=5
x+2y=7 Add them up
4x=12 Solve for x
x=3
3+2y=7 Plug it back into either one of the parent functions and solve for y
2y=4
y=2
(3,2) That's the point where the two lines intersect each other.

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]
