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

The equation below can be used to find the length of a foot or forearm when you know one or the other.
(length of the foot) = 0.860 • (length of the forearm) + 3.302
If you let y = length of the foot and x = length of the forearm, this equation can be simplified to
y = 0.860x + 3.302.
Using this equation, how long would the foot of a person be if his forearm was 17 inches long?

brian has $45.25 saved and earns $7.25/week. Dakota has $25.25 saved and earns $9.75/week. In how many weeks will they have the same amount?
Explanation pleaseeeeeeee
ASAPPPPPPPPPP!!!!!!!!!!!!!!
They will have same money after 10 weeks.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Brian has $45.25 saved and earns $7.25/week. Dakota has $25.25 saved and earns $9.75/week.
Let the number of weeks be x.
Now, money earned by Brain x weeks is 45.25+7.25x
Money earned by Dakota x weeks is
25.25+9.75x
Now, 45.25+7.25x=25.25+9.75x
2x=20
x=10
Therefore, they will have same money after 10 weeks.

18≥5K+4K
Answer:
k≤2
Step-by-step explanation:
18≥5k+4k
Step 1: Simplify both sides of the inequality.
18≥9k
Step 2: Flip the equation.
9k≤18
Step 3: Divide both sides by 9.
9k
/9≤18/9
k≤2
The solution to the inequality 18≥5K+4K is K ≤ 2.
To solve the inequality 18 ≥ 5K + 4K, we can combine the like terms on the right-hand side and simplify:
18 ≥ 5K + 4K
Combining the like terms:
18 ≥ 9K
We want to isolate the variable K on one side of the inequality.
Divide both sides of the inequality by 9:
(18/9) ≥ (9K/9)
2 ≥ K
Therefore, the solution to the inequality is K ≤ 2.

s=8
Step-by-step explanation:
Let's solve your equation step-by-step.
s(11−s)=24
Step 1: Simplify both sides of the equation.
−s2+11s=24
Step 2: Subtract 24 from both sides.
−s2+11s−24=24−24
−s2+11s−24=0
Step 3: Factor left side of equation.
(−s+3)(s−8)=0
Step 4: Set factors equal to 0.
−s+3=0 or s−8=0
s=8

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.

What enables afghanistan to grow the crops that it does
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.
