Answer 1

Answer:

He used 6 bananas at .50 which cost $3.00

12 oranges at .75 which cost $9.00 and

3 papayas at $1.25 which cost $3.75

Step-by-step explanation:

We can set up a system of equations using the information given.

b for banana, r for orange, p for papaya

b + r + p = 21. Also given r = 2b So substitute to simplify for calculating two unknowns:

b + 2b + p = 21 The number of items.

50b + 75(2b) +125p = 1575 The cost.

I multiplied everything by 100 to eliminate the decimals.

To solve by substituion, rewrite the first equation to get a value for p in terms of b

p = 21 - 3b

Substitute this value in the second equation and solve for b.

50b + 150b + 125(21–3b) = 1575

200b +2625 –375b = 1575 Subtract 2625 from both sides and combine the like terms:

–175b = 1575 –2625

–175b = –1050. Divide both sides by –175

b = 6

Substitute in the original equation to find the amount of each fruit:

b + r + p = 21

b = 6 bananas

r = 2b. 2(6) = 12 oranges. I used r so as not to mix up o with 0.

6 + 12 + p = 21

p = 21 –18

p = 3 papayas

(x% of 60 is 3.006, 10% of 111 is y)

Answers

Answer:

x = 5.01%

y = 11.1

Step-by-step explanation:

[tex]\frac{percent}{base} = \frac{rate}{100}[/tex]

Model:

50% of 120 is 60

Rate (%) = 50

Base (of) = 120

Percent (is, part) = 60

Thus, x in the first problem is the rate.

[tex]\frac{3.006}{60} =\frac{x}{100}[/tex]. Cross multiply, and we get:

x = 5.01

To check, multiply 5.01% × 60 = 3.006

For the second problem, multiply 10% with 111 to get the percent, which is 11.1

Answer:

We have to find the product of ,

(a+3)(a-2)

We will use the identity

(x+a)(x+b)=x² + (a+b)x+ab

So, (a+3)(a-2)=a²+(3-2)a+ (3)×(-2)

= a²+1 × a -6

= a²+a-6

Or , you can use the following method, to find the product.

a×(a-2)+3×(a-2)

=a² -2 a + 3 a-3×2

=a²+a-6

Find x and y
(45-45-90 formula)

Answers

i think itss this 45 45 90 triangle ratio

In a 45 45 90 triangle, the ratios are equal to: 1 : 1 : 2 for angles (45° : 45° : 90°) 1 : 1 : √2 for sides (a : a : a√2)Jun 26, 2020

Over here, we have a 45-45-90 special right triangle.

According to base angle theorem converse, this triangle is a congruent triangle so x = 14.

In a 45-45-90 triangle, the hypotenuse is the leg multiplied by [tex]\sqrt{2}[/tex]

So it would be:
