Answer:

When Amina is 18. Saad would be;

k. 14

Step-by-step explanation:

Let "x" represent Anita's current age and let "y" represent Saad's current age, we have;

Anita's age = 2 × Saad's age

Therefore;

x = 2 × y...(1)

In 4 years, we will get;

x + 4  = 1.5 × (y + 4)...(2)

Substituting the value of x in equation (1) into equation (2), we get;

2·y + 4 = 1.5·y + 1.5 × 4 = 1.5·y + 6

2·y + 4 = 1.5·y + 6

2·y - 1.5·y   = 6 - 4 = 2

0.5·y = 2

y = 2/0.5 = 4

Saad's current age = y = 4 years

From equation (1), we have;

x = 2 × y = 2 × 4 = 8

Amina's current age = x = 8 years

When Amina is 18, we have;

18 = 10 + 8 = 10 + x

Therefore, Amina would be 18 in 10 years time from now, from which we have;

Saad would be 10 years + y = 10 years + 4 years = 14 years in 10 years from now

Therefore, when Amina would be 18 years in 10 years from now Saad would be 14 years.

The age of Saad is required when Amina will be 18.

Saad will be K. 14 years old.

Let [tex]a[/tex] be the age of Amina

[tex]s[/tex] be the age of Saad

The age of Amina is twice as old as Saad

[tex]a=2s[/tex]

After 4 years Amina will be 50% older than Saad

[tex]a+4=(1+0.5)(s+4)\\\Rightarrow 2s+4=1.5(s+4)\\\Rightarrow 2s+4=1.5s+6\\\Rightarrow s=\dfrac{6-4}{2-1.5}\\\Rightarrow s=4[/tex]

So, Saad is 4 years old currently and Amina is [tex]2\times 4=8[/tex] years old.

They have a gap of 4 years between them.

When Amina will be 18 since Saad is younger his age will be [tex]18-4=14[/tex] years.

Answer:

Starbucks by 1 cent difference.

Step-by-step explanation:

Divide: 3.36 divided by 24 to find Starbucks. You get 14 cents per ounce

Answer: B. $870

Step-by-step explanation:

Correct on Edge2021

Korey’s operating expenses for last month would be $870

The gross profit margin is a profitability raio. Profitability ratios measures the efficiency with which a company generates profit from its asset. Gross profit margin measures the return on sales.

Gross profit margin can be calculated by dividing the gross profit (difference between revenue and cost of goods sold) by revenue (Net sales). It could be expressed as a percentage by multiplying by 100.

Therefore, Gross profit margin = (gross profit ÷ net sales) x 100

Gross profit = $3,320

Net sales = $4,350

Gross profit margin = ($3,320÷$4,350) * 100

0.763 * 100 = 76.3%

4,350 - 3,320 = 1030

That would be 870 dollar.

Answer:

10 degrees

Step-by-step explanation:

For an equilateral triangle, all three angles add up to 180, meaning that each angle is 60 degrees. Knowing that, we can substitute that number in to solve for x.

5x + 10 = 60

5x = 50

x = 10

Answer:

60 because equilateral triangle have 60-60-60 angles

Step-by-step explanation:

but for step by step:

3 (5x+10)=180

15x+30=180

15x= 150

x=10

5x+10= 5(10)+10= 60

Answer:

Number of senior citizen tickets sold= 110

Number of adults tickets sold= 290

Step-by-step explanation:

First, we need to establish a system of equations:

x= number of adults tickets

y= number of senior citizen tickets

x + y= 400

6x + 3y= 2,070

Now, we isolate x in one equation and substitute the value in the other:

x= 400 - y

6*(400 - y) + 3y = 2,070

2,400 - 6y + 3y = 2,070

330 = 3y

110 = y

Number of senior citizen tickets sold= 110

Number of adults tickets sold= 290

Prove:

290 + 110= 400

6*290 + 3*110= 2,070

Answer:

Henry still has to mow 75% of the laws.

Step-by-step explanation:

It is given that Henry has 15 lawns mowed out of a total of 60 lawns.

We need to find: What percent of the lawns do Henry still have to mow?

Henry has 60 lawns in total.

He mowed 15 out of them.

The percentage of lawns mow = [tex]\frac{15}{60} \times 100=25 \%[/tex]

Henry mowed 25% of total lawns.

The percent of laws still have to mow = 100%-25%

The percent of laws still have to mow = 75%

Hence, Henry still has to mow 75% of the laws.
