Answer:

Gary can go 4.9 miles in 84 minutes.

Step-by-step explanation:

First, you need to determine the amount of hours 84 minutes represent considering that 60 minutes are equal to an hour:

60 minutes → 1 hour

84 minutes →      x

x=(84*1)/60=1.4 hours

Now, 1.4 hours would be the time which is x and you can replace the value on the formula to find y:

y=3.5x

y=3.5(1.4)

y=4.9

According to this, the answer is that Gary can go 4.9 miles in 84 minutes.

Answer:

24 candy bars

Step-by-step explanation:

3 = $2.17

x = $17.36

cross-multiplying, we have;

x = (17.36 × 3)/2.17

x = 24

Therefore, you can buy 24 candy bars

Answer:

The entire shape is called a pentagon since it has 5 sides. However, it is not a perfect pentagon since the side and angle values are not congruent. So it would be an irregular pentagon to be more specific.

Step-by-step explanation:

Answer:

irregular pentagon

Answer:

x > 25

Step-by-step explanation:

This question relates to algebra. We can solve this problem by creating a variable for the solution (which we will find). We will link the variable in an equation l with the information given.

So let's translate each piece of information mathematically. First, the question tells us "Three times a number." The first part uses multiplication (times) linked to our number (we will use x for our variable). So we write:

3x

The second part is "increased by twice the number" Increasing is adding (+) so we add two times the number. So:

3x + 2x

The final part says "is greater than 125"  so we need to use the > sign

3x + 2x > 125

Now we can solve by collecting like terms and moving them to a different side.

5x > 125

x > 25

Answer: Jenns account has the greater simple interest rate

Step-by-step explanation: The formula for simple interest is:

Where A is the final amount after investment, P is the initial amount, r is the rate of interest and t is the time periods.

For Lindsey:

Solve for r

Lindsey simple interest was 1.2% annually

For Jenn:

Jenn simple interest was 1.5% annually

Therefore Jenns account has the highest simple interest rate.

Answer:

y =  [tex]\frac{1}{3}[/tex] x - 3 ⇒ 3rd answer

y =  [tex]\frac{1}{3}[/tex] x + 7 ⇒ 4th answer

y =  [tex]\frac{1}{3}[/tex] x + 3.63917 ⇒ 6th answer

y =  [tex]\frac{1}{3}[/tex] x ⇒ 8th answer

Step-by-step explanation:

The product of the slopes of the perpendicular lines is -1

The form of the linear equation is y = m x + b, where

∵ The equation of the given line is y = -3x + 2

→ Compare it with the form of the equation above

∴ m = -3

→ To find the slope of the perpendicular line to it reciprocal it and

    change its sign

∴ The slope of the perpendicular line to it is = [tex]\frac{1}{3}[/tex]

→ Choose all the equations that have m = [tex]\frac{1}{3}[/tex]

∴ y =  [tex]\frac{1}{3}[/tex] x - 3 ⇒ 3rd answer

∴ y =  [tex]\frac{1}{3}[/tex] x + 7 ⇒ 4th answer

∴ y =  [tex]\frac{1}{3}[/tex] x + 3.63917 ⇒ 6th answer

∴ y =  [tex]\frac{1}{3}[/tex] x ⇒ 8th answer

From the looks of the graph, it seems that the teacher earned either $40 a hour or $20 a hour.

Step-by-step explanation:

Answer:

The number is 2

Step-by-step explanation:

0.63

× 0.24

= 252

+1260

=0.1512

step 1

The place value of 4 in one 0.24 is hundredth. Using 4-hundredth to multiply 063 gives 252

The place value of 2 in 0.24 is tenth

Using 2-tenth to multiply 063 gives 1260

Hence, 0.63 times 0.24 equals 252 plus 1260 equals 1.512

Answer:

[tex]x=2, y=3[/tex]

Step-by-step explanation:

Given equations:

[tex]10x-7y=-1[/tex]

[tex]-2x-7y=-25[/tex]

We can subtract the two equations from each other to eliminate [tex]y[/tex] to solve for [tex]x[/tex]:

[tex]10x-7y-(-2x-7y)=-1-(-25)[/tex]

[tex]10x-7y+2x+7y=-1+25[/tex]

[tex]12x=24[/tex]

[tex]x=2[/tex]

Now, we can use substitution to solve for [tex]y[/tex]:

[tex]10x-7y=-1[/tex]

[tex]10(2)-7y=-1[/tex]

[tex]20-7y=-1[/tex]

[tex]7y=21[/tex]

[tex]y=3[/tex]

∴ [tex]x=2, y=3[/tex]

Hope this helps :)

Step-by-step explanation:

Answer:

The temperature of both appliances is 70° after 6 hours.

At 6 hours, both temperatures will be equal

Step-by-step explanation:

Equations

Let's call

T1 = Temperature inside of the refrigerator

T2 = Temperature inside of the oven.

x  =  Time in hours elapsed since the power goes out.

We know the temperature of the refrigerator rises at 5° per hour. Thus the function that models its temperature is:

T1 = 40 + 5x

We are also given the oven temperature drops by 45° per hour, thus:

T2 = 340 - 45x

a) Find the value of x for both temperatures to be the same.

We equal T1 and T2:

40 + 5x = 340 - 45x

Adding 45x

40 + 5x + 45x = 340

Subtracting 40:

5x + 45x = 340 - 40

Operating:

50x = 300

x = 300/50

x = 6

At 6 hours, both temperatures will be equal

b)

The common temperature can be found by substituting x in any function:

T1 = 40 + 5x = 40 + 5(6) = 40 + 30 = 70

T2 = 340 - 45x = 340 - 45(6) = 70

The temperature of both appliances is 70° after 6 hours.

$305 hope this helps!!! :)

Step-by-step explanation:

(A)

Let [tex]x[/tex] be the number of T-Shirts and [tex]y[/tex] be the total costs so that the total cost is:

                       Total Cost= $25+ $8 times the number of T-Shirts

      (B)                                               [tex]y=25+8x[/tex]

     For 35 members we need 35 T-Shirts so using the Linear model from part (A) substitute [tex]x[/tex] to 35 and solve for [tex]y[/tex]:

                                              [tex]y=25+8(35)[/tex]

                                               [tex]y=25+280[/tex]

                                                  [tex]y=305[/tex]

Step-by-step explanation:

Answer:

16.5 pages

Step-by-step explanation:

Number of pages Ingrid types = 3

Number of pages Tanya types = 4.5

The proportion to find how many pages Tanya would have typed (x), if Ingrid typed 11 pages would be as follows:

3 : 4.5 = 11 : x

Thus:

[tex] \frac{3}{4.5} = \frac{11}{x} [/tex]

Cross multiply

[tex] 3*x = 11*4.5 [/tex]

[tex] 3x = 49.5 [/tex]

Divide both sides by 3

x = 16.5 pages

Answer:

Option D: 6:12 is correct answer.

Step-by-step explanation:

We can find the simplest form of ratio to compare it with the given ratios.

According to given statement,

The ratio is:

[tex]No.\ of\ Blue\ Paint\ Gallons: No.\ of\ red\ paint\ gallons\\2:4\\Simplifying\\1:2[/tex]

Now we will check if the given options can be simplified to 1:2

So,

Option A:

[tex]8:12\\2:3[/tex]

Option B:

[tex]8:24\\1:3[/tex]

Option C:

[tex]3:5[/tex]

Option D:
