Answer:

To find the mpg all we have to do is divide the numbers in the ratio.

119 miles / 3.5 gallons = 34 mpg

77 mi / 2.2 gal = 35 mpg

153 mi / 4.25 gal = 36 mpg

Answer:

24

Step-by-step explanation:

Take the total amount of margarine used and divide it by the used per batch. 375/125 equals 3. This means James made 3 batches so we multiple the ammount of flapjacks per batch by the number of batches. 3*8 equals 24.    

Answer:

24 flapjacks

Step-by-step explanation:

One recipe of flapjacks takes 125g of margarine and James is using 375. To find out how many recipes James is making divide the amount of margarine he is using (375g) by the amount of margarine needed in 1 recipe (125g).

375÷125=3

One recipe makes 8 flapjacks and since James is making 3 recipes you multiply 3 by 8 to get the number of flapjacks that James is making.

8*3=24

Answer:

Step-by-step explanation:

Perimeter 165 cm

1st.   65 cm < 2s

3rd.  10 cm < s

The 2nd side is twice than the first side but 10cm longer than the

3rd side, so it'll be

2nd.   2s + 10

a triangle has a perimeter of 165 cm. the first side is 65cm less than twice the second side. the third side is 10cm less than the second side. write and solve an equation to find the length of each side of the triangle

FIRST, we need variables. Once we define variables, it's much easier to turn this word problem into a math problem.

Let a = first side

Let b = second side

Let c = third side

NOW, we can turn the words into equations:

"a triangle has a perimeter of 165 cm."

a + b + c = 165

"the first side is 65cm less than twice the second side."

a = 2b - 65

"the third side is 10cm less than the second side."

c = b - 10

Before we finish, I have to ask: Who writes problems like this??? Pointless problems like these are why kids don't like math! Ugh. Drives me crazy. It's a shame, because solving math problems really does have a certain satisfaction, once you learn how. [Okay. I'm done. Back to the problem.]

If we could get this to have only one variable, we could solve it. Substitution to the rescue!

a + b + c = 165 (rewrote equation from above)

(2b - 65) + b + (b - 10) = 165 (substituted "a" and "c" from equations above)

See how that works? Let's solve it.

2b - 65 + b + b - 10 = 165 (dropped the parentheses, because there was nothing to distribute, not even a minus sign)

4b - 75 = 165 (combined like terms)

4b = 240 (added 75 to both sides)

b = 60 (divided both sides by 4)

We found the second side! We can find the first and third sides using those equations from above:

a = 2b - 65

a = 2*60 - 65

a = 120 - 65

a = 55

c = b - 10

c = 60 - 10

c = 50

All done.

Answer:

5 units

Step-by-step explanation:

The points are:

[tex]A(-2, 5)[/tex]

[tex]B(-2, -7)[/tex]

[tex]C(-6, -4)[/tex]

Considering the sides as vectors, we have:

[tex]\overrightarrow{AB}, \overrightarrow{AC},\overrightarrow{CB}[/tex]

Once

[tex]\overrightarrow{AC} = C - A =(-6, -4) -(-2, 5) = (-6+2, -4-5) = (-4, -9)[/tex]

[tex]\overrightarrow{AB} = B - A =(-2, -7) -(-2, 5) = (-2+2, -7-5) = (0, -12)[/tex]

[tex]\overrightarrow{CB} = B - C =(-2, -7) -(-6, -4) = (-2+6, -7+4) = (4, -3)[/tex]

[tex]\Vert \overrightarrow{AC} \Vert = \sqrt{x^2 + y^2} = \sqrt{(-4)^2+(-9)^2} = \sqrt{16+81}= \sqrt{97}[/tex]

[tex]\Vert \overrightarrow{AB} \Vert = \sqrt{x^2 + y^2} = \sqrt{0^2+(-12)^2} = \sqrt{144}= 12[/tex]

[tex]\Vert \overrightarrow{CB} \Vert = \sqrt{x^2 + y^2} = \sqrt{4^2+(-3)^2} = \sqrt{16+9}= 5[/tex]

Answer:

Correct method will be: Multiply the fraction by StartFraction 5 over 5 EndFraction to get a denominator of 100 and then write the numerator as hundredths using a decimal point.

Option A is correct.

Step-by-step explanation:

Renaldo will write [tex]\frac{3}{20}[/tex] as a decimal.

We need to choose methods he should use.

To convert fraction into decimal we need to make denominator the multiple of 10

If we multiply 20 by 5 we get 100, so multiplying the given fraction [tex]\frac{3}{20}[/tex] by [tex]\frac{5}{5}[/tex] because we need to multiply both by numerator and denominator

So, [tex]\frac{3}{20}\\=\frac{3}{20}\times \frac{5}{5}\\=\frac{15}{100}\\=0.15[/tex]

So, Correct method will be: Multiply the fraction by StartFraction 5 over 5 EndFraction to get a denominator of 100 and then write the numerator as hundredths using a decimal point.

Option A is correct.

Answer:

it A. Multiply the fraction by StartFraction 5 over 5 EndFraction to get a denominator of 100 and then write the numerator as hundredths using a decimal point.

Answer:

7(2 +5)

Step-by-step explanation:

Both the numbers (14 and 35) have a GCF (greatest common factor) of 7. If you divide both numbers by 7, you get 2 and 5. Therefore, your answer would be 7(2 +5)

Answer:

I guess it is A because it is the closest to the answer for the expression 14 + 35.

Answer:

x=15

Step-by-step explanation:

(x-6)+8=17 then remove unnecessary parentheses x-6+8=17 then calculate the sum x + 2 = 17 the move constant to the right hand side and change its sign x = 17 - 2 then subtract the numbers x=15 btw you should use photo math that's what I used

|x - 6| + 8 = 17

Subtract 8 from both sides.

|x - 6| + 8 - 8 = 17 - 8

|x - 6| = 9

Set x - 6 to 9 and -9, which leads to two cases.

x - 6 = 9

x = 9 + 6

x = 15

x - 6 = -9

x = -9 + 3

x = -6

Which is the answer?

Plug both values into the original absolute value equation to see which yields a true statement.

Let x = 15

|15 - 6| + 8 = 17

|9| + 8 = 17

9 + 8 = 17

17 = 17

Let x = -6

|-6 - 6| + 8 = 17

|-12| + 8 = 17

12 + 8 = 17

20 DOES NOT EQUAL 17.

Answer: x = 15

Answer:

Sarah is incorrect.

Step-by-step explanation:

By plugging 10 in as 'x' to the equation, we get y=21+(2*10). 2 x 10 is 20, and 20 + 21 is not 42 - it's 41. So, Sarah is incorrect.

Answer:

Sarah is not correct because if David already knows 21 recipes and learns 2 recipes per week, then he will know only 41 recipes after 10 weeks, not 42.

Step-by-step explanation:

To see if Sarah is correct, let's replace the y in the equation with 42 and the x with 10:

y = 2x + 21

42 = 2(10) + 21

42 = 20 + 21

42 [tex]\neq[/tex] 41

Sarah is wrong.

(solve for x)

The domain of the function f(y) = (5y - 8)/11 is the set of all real numbers.

Dom(f(y)) = R.

Suppose we have an ordered pair (x, y) then the domain of the function is the set of values of x and the range is the set of values of y for which x  is defined.

Given a function f(y) = (5y - 8)/11.

It is a real function and the domain of the function is the set of all real numbers.

There are no restrictions as the denominator is constant and no such values of 'y' make the denominator zero.

Answer:

Angle LMO = 50°

Step-by-step explanation:

1) We need to solve for x.

We know angle LMN = 90°, and that angles LMO and NMO add up to angle LMN. That gives us this equation:

3x + 38 + 10x = 90

Now, we solve for x!

Combine like terms

13x + 38 = 90

Subtract 38 from both sides

13x = 52

Divide both sides by 13

x = 4

Now we know what x is.

2) Plug in x to angle LMO's given value (3x + 38)

3(4) + 38 = angle LMO

12 + 38 = angle LMO

50° = angle LMO

Answer:

b=121, a and c=59

Step-by-step explanation:

b and 121 are congruent angles, so they are equal to each other.

each side of a line equals 180 degrees, so subtracting 180-121=c gives you 59 degrees.

a and c are congruent angles so they are also equal to each other
