Answer:

Step-by-step explanation:

cos(∠X) = adj./hyp.

arccos(adj./hyp.) = ∠X

arccos(13/18) = 43.761...≈ 43°

Answer:

x + 2y = -2

Step-by-step explanation:

Well let's examine the relation between x and y in a perpendicular line.

We can use the fact that for a line Ax + By = C, any line with equation Bx + (-A)y = D is perpendicular (swapping A and B gives a mirror image with respect to the line x=y and changing one of the signs gives a mirror image with respect to axis x or y. Those two together give a perpendicular line).

So we're looking for a line with equation x + 2y = D

We know what it passes through the point (6, -4), so let's input it into the equation x + 2y = D

6 + 2*(-4) = D

6 - 8 = D

D = -2

So the equation is x + 2y = -2

note that 2x + 4y = -4

or any other multiple also works.

Answer:

£ 4.20

Step-by-step explanation:

1 kg= £1.20

3.5 kg = £1.20*3.5

=£ 4.20

The cost of the apples being weighed on the scales would be £ 4.20

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Multiplication is the mathematical operation that is used to determine the product of two or more numbers.

We are given that Apples are sold in a supermarket at £1.20 per gram.

Therefore, we know that

1 kg= £1.20

For 3.5 kg

= £1.20 x 3.5

=£ 4.20

The cost of the apples is £ 4.20

Answer:

Simple interest after 2 year = $36

Step-by-step explanation:

Given:

Amount invested = $300

Number of year amount invested = 2 year

Rate of interest per year = 6% = 6/100 = 0.06

Find:

Simple interest after 2 year

Computation:

Simple interest formula;

Simple interest = [Amount invested][Rate of interest][Number of year]

Simple interest after 2 year = [300][0.06][2]

Simple interest after 2 year = [18][2]

Simple interest after 2 year = $36

Answer:

15

Step-by-step explanation:

x - y = 10, then x = 10 + y

x + y = 20

substitute for x:

10 + y + y = 20

2y = 10

y = 5

x = 10 + 5 = 15

Answer:

Amount of interest pay by Sam = $400

Step-by-step explanation:

Given:

Amount of loan taken by Sam = $5,000

Monthly payment made by Sam = $150

Number of year payment made by Sam = 3 Year

Find:

Amount of interest pay by Sam

Computation:

Total amount pay by Sam in 3 year = Monthly payment made by Sam x 12 x 3

Total amount pay by Sam in 3 year = 150 x 12 x 3

Total amount pay by Sam in 3 year = $5,400

Amount of interest pay by Sam = Total amount pay by Sam in 3 year - Amount of loan taken by Sam

Amount of interest pay by Sam = $5,400 - $5,000

Amount of interest pay by Sam = $400
