Answer:

3 bananas and 12 apples.

Step-by-step explanation:

105b+ 75a = 1215     where b is number of bananas and a is number of apples.

Divide each number by 15:

7b + 5a =  81

5a must end in 5 or 10 so 7b must end in 1 or 6.

So we try:

21 and 60:

7 * 3 + 5 *1 2 = 81

So b = 3 and a = 12.

The solution is

The number of bananas is = 3 bananas

The number of apples is = 12 apples

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number of apples be = a

Let the number of bananas be = b

Now , the equation will be

The number of calories in bananas = 105 calories

The number of calories in apples = 75 calories

The total calories Mary takes = 1215 calories

So ,

Total calories Mary takes = number of apples x  number of calories in apples +  number of bananas x number of calories in bananas

Substituting the values in the equation , we get

75a + 105b = 1215

Divide by 15 on both sides of the equation , we get

5a + 7b = 81

So , substituting the values of a = 12 and b = 3 , we get

5 ( 12 ) + 7 ( 3 ) = 81

60 + 21 = 81

81 = 81

Therefore , the vale of a is 12 and value of b is 3

Hence ,

The number of bananas is 3 bananas

The number of apples is 12 apples

Answer:

Plot these points

(1,935)

(2,870)

(3,805)

(4,740)

(5,675)

Slope= -65

y intercept = 1000

and what it's saying is that we travel at a speed of 65 units an hour and we start 1000 miles away

Step-by-step explanation:

Just graph these points which you can get by plugging in the numbers

1000-65= 935

(1,935)

1000-65*2=870

(2,870)

1000-65*3= 805

(3,805)

1000-65*4=740

(4,740)

1000-65*5= 675

(5,675)

B:

y= mx+b where m is the slope and B is the y intercept

we can re write the equation as follows

-65x+1000

It's pretty clear that -65 is the slope and 1000 is the y intercept

Answer:

The diameter of horse hair is twice as thick as the diameter of the human hair.  

Step-by-step explanation:

The diameter of a human hair = [tex]6.5\times 10^{-4}\ \inches[/tex]

The diameter of a horse hair = [tex]1.3\times 10^{-3}\ \inches[/tex]

Dividing the diameter of a horse hair to the diameter of a human hair as follows :

[tex]\dfrac{\text{Diameter of human hair}}{\text{Diameter of horse hair}}=\dfrac{6.5\times 10^{-4}}{1.3\times 10^{-3}}\\\\\dfrac{\text{Diameter of human hair}}{\text{Diameter of horse hair}}=\dfrac{1}{2}\\\\\text{Diameter of horse hair}=2\times \text{Diameter of human hair}[/tex]

So, the diameter of horse hair is twice as thick as the diameter of the human hair.  

Answer:

The horse hair is 2 times as thick as the human hair.

Answer:

Amount of paint to be bought = 10 gallons

Step-by-step explanation:

Amount of paint needed by Mrs. Sullivan to paint her house = 12 gallons

She is already having paint = 8 quarts

Since, 1 quart = 0.25 gallons

Therefore, 8 quarts = 8 × 0.25

                                 = 2 gallons

So, amount of paint she is already having = 2 gallons

Amount of paint to be bought = 12 - 2

                                                    = 10 gallons

Answer:

2* 8n* 8n* 8n*8n

Step-by-step explanation:

Break it down 2(8n)^4 because 4 is the exponent you will multiply 8n four times so it will be 8n*8n*8n*8n so add the 2 to it and it will be 2*8n*8n*8n*8n. Hope this help :)  

The expression 2(8n)⁴ is equivalent to 2¹³n⁴ or 8192n⁴ after simplifying.

It is defined as the combination of constants and variables with mathematical operators.

We have:

[tex]\rm = 2(8n)^4[/tex]

[tex]\rm 2\times 8^4\times n^4\\\\\rm 2\times (2^3)^4\times n^4\\\\\rm 2\times 2^1^2\times n^4\\\\\rm 2^1^3\times n^4\\\\\\\rm 2^1^3 n^4\\\\or\\\\8192n^4[/tex]

Thus, the expression 2(8n)⁴ is equivalent to 2¹³n⁴ or 8192n⁴ after simplifying.

scale

1cm=14miles

hence if

        1cm represents 14miles

then  14.6 cm will be x

cross multiply

x= 14.6*14

x=204.4 miles

Hence the distance is 204.4 miles
