2 in 2:3 is the amount of blue paint

3 in 2:3 is the amount of yellow paint

Figure out how many times to multiply 2 to get 16:

16/2=8

Now, multiply 3 by 8, which would be equal to 24.

Ratio: 16:24

[tex] {x}^{2} = {24}^{2} - {23}^{2} \\ \\ {x}^{2} = 576 - 529 \\ \\ {x}^{2} = 47 \\ \\ x = \sqrt{47} [/tex]

Answer:

33.3

Step-by-step explanation:

Reference angle = 39°

Opposite = 27

Adjacent = x

Apply TOA. Thus:

Tan 39 = Opp/Adj

Tan 39 = 27/x

x * Tan 39 = 27

x = 27/Tan 39

x = 33.3422232 ≈ 33.3 (nearest tenth)

Answer:

12

Step-by-step explanation:

his he had lost 12 of his marbles then he would only have 12 left to begin with.

to do this we can do the equation:

24/0.5 (the 0.5 is the represent that the 24 marbles had been split into two, a half for each party)

this would then give use our quotient of 12 marble he had lost

Answer:

[tex]\Huge\boxed{240ft^2}[/tex]

Step-by-step explanation:

Hello There!

The figure shown is a trapezoid with the following dimensions

base 1 = 12ft

base 2 = 20 ft

height = 15 ft

Given these dimensions we need to find the area

We can do this by using the area of a trapezoid formula

[tex]A=\frac{a+b}{2} h[/tex]

where a and b = bases and h = height

Knowing the dimensions all we have to do is plug in the values

[tex]A=\frac{12+20}{2} 15\\12+20=32\\\frac{32}{2} =16\\16*15=240\\A=240ft^2[/tex]

So we can conclude that the area of the floor that needs to be replaced with tile is 240 ft²

Answer:

4 POUNDS OF FLOUR

Step-by-step explanation:

The number of cups of flour he added is 4.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Bowl weight = 1(1/2) pounds

Number of cups of flour weight = x pounds

Now,

Total weight = 2(3/4) pounds

1(1/2) + x = 2(3/4)

x = 11/4 - 3/2

x = (11 - 6)/4

x = 5/4

Now,

Weight of each cup of flour = 5/16 pounds

Now,

The number of cups of flour.

= 5/4 ÷ 5/16

= (5 x 16) / (4 x 5)

= 4

Thus,

The number of cups of flour is 4.

Answer 12.9

Answer:

The gain percent made by shopkeeper is 10.5%.

Step-by-step explanation:

Given:

Price at which goods are marked = 30%

Discount on the marked price = 15%

To Find:

Gain percentage of the shopkeeper

Solution:

Let the cost price of the product be = 100

Therefore,

MP = 30 + 100 = 130

Since discount is 15%. thus -

Discount = 15/100 x 130

= 19.5

Selling price = MP - Discount

SP = 130 - 19.5

= 110.5

Profit = SP - CP

= 110.5 - 100

= 10.5

Calculating the gain%

Gain% = 10.5/100 x 100

= 10.5

Answer: The gain percent made by shopkeeper is 10.5%.

Answer:

Step-by-step explanation:

n=3p, d=p-2

10d+5n+p=110 using n and d from above makes this become

10(p-2)+5(3p)+p=110

10p-20+15p+p=110

26p-20=110

26p=130

p=5

n=3p=3(5)=15

d=p-2=5-2=3

So she has 3 dimes, 15 nickels, and 5 pennies.

Answer: because they were right for each other.

Step-by-step explanation:

The cause due to which the triangles 30-60-90 married the triangle 45-45-90 would be:

They were right for each other.

The sum of property of triangle states that the three angles of triangle give the sum of 180°.

Given that,

Two sets of triangles having the measures:

First set = 30°-60°-90°

Second set = 45°-45°-90°

The first set marries the other as they both are right i.e. 90° to one another and give an equal sum of 180°.

Thus, the above answer is correct.

8 × 9 = 72

33 + 72 = 105

The answer is 105

31 - 20 = 11

11 × 3 = 33

The answer is 33

102 - 6 = 8 - 5

102 - 6 = 96

96 = 8 - 5

8 - 5 = 3

96 = 3

93 = 3 is false so therefor, this equation has no solution.

4th Equation:

102 = 12 + 4 × 7 - 2

4 × 7 = 28

102 = 12 + 28 - 2

12 + 28 = 40

102 = 40 - 2

40 - 2 = 38

102 = 38

102 = 38 is false so, it means that this equation has no solution.
