Answer:

y = 0.59x

Step-by-step explanation:

Cost per pound of banana = $0.59

If Number of banana's = x

Total Cost of an item = price per item * number of items

Therefore,

Total cost, y = price per pound of banana * number of bananas

y = 0.59 * x

y = 0.59x

Answer:

Point C

Step-by-step explanation:

X axis is bottom row and Point C is directly on it.

Answer:

r = 2.7%

Step-by-step explanation:

Interest rate compounded continuously

r = ln(A/P) / t

Where,

r = interest rate

A = future value

P = principal

t = time

r = ln(A/P) / t

r = ln(13,006.40/8,000) / 18

= ln(1.6258) / 18

= 0.4860000023303 / 18

= 0.0270000001294

Approximately

r = 0.027

Convert value of r to percentage

r = 0.27 × 100

r = 2.7%

Answer:

Each customer bought 45 boxes which is equivalent to mangoes 3240 in total.

Step-by-step explanation:

1. Subtract 3 boxes from the total of 138 imported boxes. ( 3 boxes are the 72 mangoes for his friends )

2. Divide 135 by 3 ( The amount of customers ) = 45 boxes per customer.

3. 45 x 24 ( The amount of mangoes in each box ) = 1080

4. 45 boxes/1080 mangoes per customer.

To recheck:

1080 x 3 ( The amount of customers again ) = 3240.

135 x 24 ( The amount of mangoes per box ) = 3240.

I Hope this helped! :)

Answer:

Answer:

-191.10

Step-by-step explanation:

When you divide 56/23 you get 2.4, 2.4 is negative.

Multiply 2.4 6 times

&

2.4^6.

You get -191.10.

I am probably wrong but I tried.

Answer:

When we know the initial population

, the next thing we need to solve the growth constant

to derive the exponential growth function.

If the problem gives the time it takes for the population to double or the doubling time

τ

. We can find the growth constant by substituting the doubling constant into the equation and solving for t.

This means that the statement is TRUE because the term for initial population cancels out when solving for k and the doubling time is given.

Answer and Step-by-step explanation:

To find the sequence, we must plug in values for n and solve, starting with 0.

f(0) = ⁻13 - 2(0) = ⁻13

f(1) = ⁻13 - 2(1) = ⁻13 - 2 = ⁻15

f(1) = ⁻13 - 2(2) = ⁻13 - 4 = ⁻17

f(1) = ⁻13 - 2(3) = ⁻13 - 6 = ⁻19

When seeing this, we can see that the answer to the questions is A.

Step-by-step explanation:

Answer: 0.70h

Step-by-step explanation:

The hat is being sold at a 30% discount. The expression that shows this will be:

Price = h - 0.3h

When the 0.3h is subtracted from h, we have:

= 0.7h

Another way to get to that expression:

Hat is being sold at 30% discount which means that 30% has been removed from the value leaving:

= 100% - 30%

= 70%

Price is now 70% * Normal price which is denoted as h.

= 70% * h = 0.7h

Answer:

-4a

Step-by-step explanation:

Answer:

Step-by-step explanation:

a(1) = -7 (given)

a(2) = a(1) + 4 = -7 + 4 = -3

a(3) = a(2) + 4 = -3 + 4 = 1

a(4) = a(3) + 4 = 1 + 4 = 5

and so on.

Answer:

Step-by-step explanation:

Answer:

x = 1

y = 2

Step-by-step explanation:

y =8x - 6  ---------------------------------(I)

y = 2x -------------------------------------(II)

substitute y = 2x in equation (I)

2x = 8x - 6

Add 6 to both sides

2x + 6 = 8x

Subtract 2x from both sides

6 = 8x - 2x

6 = 6x

Divide both sides by 6

6/6 = x

x = 1

Substitute x = 1 in equation (II)

y = 2*1

y = 2

Answer:

c = 0.15m + 45

Step-by-step explanation:

Generally, we have the equation of a straight line as;

y = mx + b

where m is the slope and b is the y-intercept

To get the value of m, we can use the slope equation

m = (y2-y1)/(x2-x1)

Let us select two points to use from the table

we have;

(40,51) and (20,48)

So substituting these values;

m = (48-51)/(20-40) = 0.15

So we have the partially completed equation as;

y = 0.15x + b

To get the value of b, we use any of the points

Using the last, we have

51 = 0.15(40) + b

b = 45

So we have the complete equation as;

y = 0.15x + 45

using the terms in the question, we have;

c = 0.15m + 45

Answer:

Surface area of net = 310 cm²

Step-by-step explanation:

Given:

Dimension of two same rectangle = 11 cm by 9 cm

Dimension of single rectangle = 11 cm by 7 cm

Height of two triangle = 5 Cm

Base of two triangle = 7 Cm

Find;

Surface area of net

Computation:

Surface area of net = Surface area of two same rectangle + Surface area of single rectangle + Surface area of two same triangle

Surface area of net = 2[l x b] + [l x b] + 2[(1/2)(b)(h)]

Surface area of net = 2[11 x 9] + [11 x 7] + 2[(1/2)(7)(5)]

Surface area of net = 198 + 77 + 35

Surface area of net = 310 cm²

Answer:

x = 6

Step-by-step explanation:

10x + 11 + 17x + 7 = 180°

combine like terms:

27x + 18 = 180

subtract 17 from both sides of the equation:

27x = 162

divide both sides by 27:

x = 6

Answer:

7) Right triangle

8) Acute

9) Right triangle

10) obtuse

Step-by-step explanation:

Answer:

50

Step-by-step explanation:

The triangle is an isosceles triangle as shown with the lines on the sides of the triangles. That means the unknown angle is 35 degrees since angle Q cannot be 35 degrees. Solve the equation:

2x + 80 = 180

2x = 100

x = 50

Step-by-step explanation:

Cos m = 35/37 = 0.94

Cos n = 12/37 = 0.32

Sin m = 12/37 = 0.32

Sin n = 35/37 = 0.94

tan m = 12/35 = 0.34

tan n = 35/12 = 2.91
