I would choose lelia because she might have taken longer but maria ran 1 lap lelia ran 3 so lelia can run 2 1/4 (or (1/3) times faster

Answer:

Lelia should be chosen.

Step-by-step explanation:

Leila: 3 laps is going to be 3/5 x 3, which is 9/5. So she can run 1 4/5 in 7 minutes.

Maria: 1 lap is going to be 3/5. So she can run 3/5 in 3 minutes.

If you multiply 3/5 by 2, you're going to get 6/5 in 6 minutes, and then divide it by 6, which is going to give you 1/5 of a lap in 1 minute, multiply that by 7, and get 7/35. This is for Maria. If you divide 9/5 by 7, you're going to get 9/35. This is for Lelia.

Maria: 7/35 of a lap in 1 minute.

Lelia: 9/35 of a lap in 1 minute.

Lelia should be chosen.

James bought Nicole a pair of shoes for $54.99 and a bracelet for $21.99. He used a 15% off coupon and then paid 7.5% sales tax. What was the total amount James spent?​

Answers

Answer:

$70.34

Step-by-step explanation:

The total before the coupon and tax is:

$54.99 + $21.99 = $76.98

Now apply the 15% coupon:

Since the total price is 100% of the price, when you apply a 15% coupon, you pay 100% - 15% = 85% of the price. We need to find 85% of $76.98

85% * $76.98 =

= 0.85 * $76.98

= $65.43

The price after the 15% coupon, but before the tax, is $65.43

Now the total $65.43 is considered 100% of the price. The tax is 7.5%.

100% + 7.5% = 107.5%

Now we find 107.5% of $65.43

107.5% of $65.43 =

= 1.075 * $65.43

= $70.34

Answer: $70.34

it would be 70.34 dollars

angle a= 7x + 40°
angle b= 3x + 112°
Solve for x then find the meansie if angle a.
Angle A =​

Answers

Answer:

[tex]x = 18[/tex]

[tex]\angle A = 166[/tex]

Step-by-step explanation:

The question is properly presented in the attachment.

Given

[tex]\angle A = 7x + 40[/tex]

[tex]\angle B = 3x + 112[/tex]

Required

Solve for x and  [tex]\angle A[/tex]

From the attachment [tex]\angle A[/tex] and [tex]\angle B[/tex] are vertically opposite.

This means that:

[tex]\angle A[/tex] = [tex]\angle B[/tex]

Substitute values for [tex]\angle A[/tex] and [tex]\angle B[/tex]

[tex]7x + 40 = 3x + 112[/tex]

Collect Like Terms

[tex]7x -3x = 112 - 40[/tex]

[tex]4x = 72[/tex]

Make x the subject

[tex]x = \frac{72}{4}[/tex]

[tex]x = 18[/tex]

Substitute 18 for x in [tex]\angle A = 7x + 40[/tex]

[tex]\angle A = 7 * 18 + 40[/tex]

[tex]\angle A = 166[/tex]

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

7*x+40-(3*x+112)=0

Step by step solution :

STEP
1
:
Pulling out like terms

1.1 Pull out like factors :

4x - 72 = 4 • (x - 18)

Equation at the end of step

:

STEP
2
:

Equations which are never true:

2.1 Solve : 4 = 0

This equation has no solution.
A a non-zero constant never equals zero.

Solving a Single Variable Equation:

2.2 Solve : x-18 = 0

Add 18 to both sides of the equation :
x = 18

One solution was found :
x = 18

What enables afghanistan to grow the crops that it does

Answers

Answer:

Step-by-step explanation:

About 12% of the land is arable and less than 6% currently is cultivated. Normally, Afghanistan grew about 95% of its needs in wheat and rye, and more than met its needs in rice, potatoes, pulses, nuts, and seeds; it depended on imports only for some wheat, sugar, and edible fats and oils. Fruit, both fresh and preserved (with bread), is a staple food for many Afghans. Agricultural production, however, is a fraction of its potential. Agricultural production is constrained by an almost total dependence on erratic winter snows and spring rains for water; irrigation is primitive. Relatively.

Answer:

About 12% of the land is arable and less than 6% currently is cultivated.

Step 2: Subtract 24 from both sides.

−s2+11s−24=24−24

−s2+11s−24=0

Step 3: Factor left side of equation.
