Which expression is represented by the model?

Answer:

I got you bro so the sales tax is $0.80 and the total cost is $10.80

Answer:

Step-by-step explanation:

Now we have to,

→ find sales tax and total cost.

The sales tax will be,

→ 8% of $10.00

→ (10/100) × 8

→ 80/100

→ $0.8

Now the total cost will be,

→ $10 + sales tax

→ 10 + 0.8

→ $10.8

Hence, total cost is $10.8.

Answer:

$149

Step-by-step explanation:

The computation of the amount left for the shopping is shown below;

= Amount have - Electricity bill - Water bill - telephone bill

= $430 - $119  - $65 - $97

= $149

We simply deduct all expenses from the amount available so the remaining amount i.e. left would be considered for shopping

Answer:

4/8

Step-by-step explanation:

4/8 is equal to 1/2

-

4 is half of 8

Answer:

-The equation for this problem is:

y=50,000+20,000x

-The money in Sweet Sauce's account after July 31st is $190,000

-The money in the account after 2 years is $530,000.

Step-by-step explanation:

With the information provided, you can say that the money in the account would be equal to adding up the starting balance plus the profit per month for the number of months that have passed, which is:

y=50,000+20,000x, where:

y is the money in the account

x is the number of months that have passed

Now, to find the amount of money in the account after July 31st, you have to consider that this is the 7th month and you have to replace x with 7:

y=50,000+(20,000*7)

y=50,000+140,000

y=190,000

Also, to find the amount the amount of money in the account after 2 years, you have to consider that 2 years is equal to 24 months:

y=50,000+(20,000*24)

y=50,000+480,000

y=530,000

Answer:

x = 7[tex]\sqrt{2}[/tex] and y = 7

Step-by-step explanation:

Since this is 45 45 90 triangle, each leg is the same length so y = 7 too and x is always [tex]a\sqrt{2}[/tex]  so x = 7[tex]\sqrt{2}[/tex]

The values of [tex]x[/tex] and [tex]y[/tex] are required.

The required values are

[tex]x=9.9\ \text{units}[/tex]

[tex]y=7\ \text{units}[/tex]

The given triangle is a right angled triangle.

Two given angles are [tex]90^{\circ}[/tex] and [tex]45^{\circ}[/tex]

The sum of the angles is [tex]180^{\circ}[/tex]

The missing angle is

[tex]180-(90+45)=45^{\circ}[/tex]

Since, the two angles are equal the side opposite the angles will also be equal.

So,

[tex]y=7[/tex]

Applying the Pythagoras theorem.

[tex]7^2+7^2=x^2\\\Rightarrow x=\sqrt{7^2+7^2}\\\Rightarrow x\approx 9.9[/tex]

Answer:

Andrew's total income for this month is $4762.5.

Step-by-step explanation:

With the information provided, you can find the total income by calculating 5% of the sales this month and adding up this amount to his monthly salary:

sales=10,250

monthly salary=4,250

10,250*5%=512.5

4,250+512.5=4,762.5

According to this, the answer is that Andrew's total income for this month is $4,762.5.

Answer:

We will apply the formula of d=y- x/n+1

Let y be 2.2 and x be 2.1 and n= 16

Then 2.2-2.1/ 16+1

0.1/17

x+d= 2.1 + 0.1 = 2.2

x+2d= 2.1+2×0.1=2.3

x+3d= 2.1+3×0.1=2.4

x+4d= 2.1+4×0.1=2.5

x+5d=2.1+5×0.1=2.6

x+6d=2.1+6×0.1=2.7

x+7d=2.1+7×0.1=2.8

x+8d=2.1+8×0.1=2.9

x+9d=2.1+9×0.1=3

x+10d=2.1+10×0.1=3.1

x+11d=2.1+11×0.1=3.2

x+12d=2.1+12×0.1=3.3

×+13d=2.1+13×0.1=3.4

x+14d=2.1+14×0.1=3.5

x+15d=2.1+15×0.1=3.6

x+16d=2.1+16×0.1=3.7

Answer:

5 and 6

Step-by-step explanation:

Given the inequality 5x + 3 > 33?

Subtract 3 from both sides

5x + 3 - 3 > 33 - 3

5x > 30

Divide both sides by 5

5x/5 > 30/5

x > 6

Hence the value of x must be greater than 6. The values that are not greater than 6 are 5 and 6. Hence 5 and 6 are not solution for x in the inequality

Answer:

[tex]g(f(d)) = -dlog_{10}(0.5 * 10^{-4})[/tex]

Step-by-step explanation:

Given

[tex]f(d) = (0.5 * 10^{-4})^d[/tex]

[tex]g(H+) = -log_{10}(H+)[/tex]

Required

Find the composite function g(f(d))

We have:

[tex]g(H+) = -log_{10}(H+)[/tex]

Substitute f(d) for H+

[tex]g(f(d)) = -log_{10}(f(d))[/tex]

Substitute [tex]f(d) = (0.5 * 10^{-4})^d[/tex]

[tex]g(f(d)) = -log_{10}((0.5 * 10^{-4})^d)[/tex]

Apply law of logarithm

[tex]g(f(d)) = -dlog_{10}(0.5 * 10^{-4})[/tex]

Hence, the function is:

[tex]g(f(d)) = -dlog_{10}(0.5 * 10^{-4})[/tex]

Step-by-step explanation:

Answer: He pays x*0.642

Step-by-step explanation:

Suppose that we have an object with an initial price P.

If we have a discount of X%, then the new price will be:

NP = P*(1 - X%/100%)

And if we have an increase of X%, the new price is:

NP = P*(1 + X%/100%)

In this case, we have an initial item that costs x dollars, first we have a coupon for 40% off, then we have a discount of 40%.

Then the new price is:

NP = x*(1 - 40%/100%) = x*(1 - 0.4) = x*0.6

Now we add a tax of the 7%, then the final price will be:

FP = (x*0.6)*(1 + 7%/100%) = (x*0.6)*(1 + 0.07) = x*(0.6*1.07) = x*0.642

This is the total amount he pays at the register.
