1. four -ninths over four-fifths = four over nine mile per hour

2. four-fifths over four-ninths = one and four-fifths miles per hour

3. four-ninths over four-fifths = one and four-fifths miles per hour

4. four-fifths over four-ninths = four over nine mile per hour

Answer:

A unit rate is a special kind of ratio, where the second number, or the denominator, is equal to one. With a unit rate, you are comparing a quantity to one. Some common unit rates are miles per gallon, price per pound, and pay rate per hour. ... Next, divide the price by the pounds so you can find the unit rate.

Answer:

The coupon raised the cost per issue by $0.67.​

Step-by-step explanation:

Answer:

D. 3h + 2 ≥ 14

Step-by-step explanation:

Cost of Bottle water = $2

Cost of Hot dogs = $3

Number of hot dogs bought = h

Total cost of hot dogs = price × quantity

= 3 * h

= 3h

Jeff did not spend more than $14

Total cost of bottle water and hot dogs

3h + 2 ≥14

The correct answer is D

D. 3h + 2 ≥ 14

Answer:

2/3 ÷ 4

¨We use copy dot flip

The flip means make a reciprocal of the second number

2/3 * 1/4

Multiply the numerators

2*1 = 2

Multiply the denominators

3*4 =12

Put the numerator over the denominator

2/12

Simplify

1/6¨

Answer:

1/6

Step-by-step explanation:

You find a fraction that is equal 2/3 and has a multiple of 4 for the numerator. Then you have to multiply the numerator and the denominator by 2 then you get 4/6 divided by 4, since 2/3 is equal to 4/6. So the answer is 1/6.

4. 1 1/18

5. 1/4

6. 3 1/6

7. 1

Step-by-step explanation:

i will use the last one as an example, first reduce, so you would find the common denominator, in this case its 6, so you simplify 6/30 to 1/5. then you have 4/5+1/5, so since u have the same denominator, you can add the two numerators above the common denominator, so it would look like 4+1/5. then add the numbers. so you are left with 5/5 which in other words is 1. i hope this helps!

Answer:

1680 pounds

Step-by-step explanation:

Given that :

Weight of yellow fin tuna = 380 pounds

Weight of bluefin tuna = 620 pounds

If one fish of each species were caught per day

about how many more pounds of bluefin tuna than yellowfin tuna would be caught in a​ week?

Total pound of bluefin tuna caught in a week:

7 * 620 = 4340

Total pound of yellow tuna caught in a week:

7 * 380 = 2660

(4340 - 2660) = 1680 pounds

Answer:

function is a parabola, with a lowest point of -4

Step-by-step explanation:

g(x)=x^-4

g(-3)= -3^2-4 = 9-4 = 5

g(-2)= -2^2-4 = 4-4 = 0

g(-1)= -1^2-4 = 1-4 = -3

g(0)= 0^2-4 = 0-4 = -4

g(1)= 1^2-4 = 1-4 = -3

g(2)= 2^2-4 = 4-4 = 0

g(3)= 3^2-4 = 9-4 = 5

Answer:

2(3(8))+2(8)=64

Step-by-step explanation:

Here, w represents the width of the rectangle,

∵ length of the rectangle is 3 times the width of the rectangle,

So, length = 3w,

Since, the perimeter of a rectangle, P = 2(length + width)

= 2(w + 3w)

= 2w + 2(3w)

If P = 64 feet,

⇒ 2w +2(3w) = 64

⇒ 2w + 6w = 64

⇒ 8w = 64

⇒ w = 8

Verification :

P = 2(8) + 2((3(8)) = 16 + 48 = 64 feet

Hence, the first step that should be taken to verify that the width of the rectangle is 8 is 2(3(8))+2(8)=64

Note : a solution obtain from an equation is verified by substituting the value in the equation.

Answer:

x = 2

Step-by-step explanation:

First isolate the variable:

10x - 4 = 16

      +4   +4

10x = 20

Then get x by itself:

10x = 20

x = 20/10

x = 10

Answer:

x = 2

Step-by-step explanation:

First distribute:

-3 (x+4) = 6(-x-1)

-3x -12 = -6x -6

Isolate the variable:

-6 = -3x

Simplify:

-6/3 = x

x = 2

Step-by-step explanation:

A = 42°

B= 23°

F = 115°

Step-by-step explanation:

The required measures of the three angles in triangle ABF are A = 23°, B = 42°, and F = 115°.

Alternate Interior Angles are defined as the pair of angles created on the inner side of the parallel lines

Given that Lines AB and CD are parallel.

To determine the measures of the three angles in triangle ABF.

For finding ∠F,

∠CDF = 180° - 157° = 23°

∠F = 180° - ∠C - ∠CDF

∠F = 180° - 42° - 23°

∠F = 115°

However, if a transversal intersects two parallel lines, then each pair of alternate interior angles is equal.

So ∠A = ∠CDF = 23°

And ∠B = ∠C = 42°

Thus, the required measures of the three angles in triangle ABF are A = 23°, B = 42°, and F = 115°.

Answer:

(0,8)

Step-by-step explanation:

The parabola intercepts at 8 on the y axis, and since the interception has zero x value, x=0.

The graph the coordinate of the y-intercept of the parabola is (0, 8).

The points where a line crosses an axis are known as the x-intercept and the y-intercept, respectively.

When you know the slope of the line to be investigated and the given point is also the y intercept, you can utilise the slope intercept formula, y = mx + b. (0, b). The y value of the y intercept point is denoted by the symbol b in the formula.

Given:

From the parabolic graph we can see that the intersecting point (0, 8)

Now, the y- intercept is the point in the vertical axis.

As, from the graph the coordinate of the y-intercept of the parabola is (0, 8)

Answer: y=15

Step-by-step explanation:

Solution for (5y+3)+(4y+8)=146 equation:

Simplifying

(5y + 3) + (4y + 8) = 146

Reorder the terms:

(3 + 5y) + (4y + 8) = 146

Remove parenthesis around (3 + 5y)

3 + 5y + (4y + 8) = 146

Reorder the terms:

3 + 5y + (8 + 4y) = 146

Remove parenthesis around (8 + 4y)

3 + 5y + 8 + 4y = 146

Reorder the terms:

3 + 8 + 5y + 4y = 146

Combine like terms: 3 + 8 = 11

11 + 5y + 4y = 146

Combine like terms: 5y + 4y = 9y

11 + 9y = 146

Solving

11 + 9y = 146

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-11' to each side of the equation.

11 + -11 + 9y = 146 + -11

Combine like terms: 11 + -11 = 0

0 + 9y = 146 + -11

9y = 146 + -11

Combine like terms: 146 + -11 = 135

9y = 135

Divide each side by '9'.

y = 15
