Answer:
I got you bro so the sales tax is $0.80 and the total cost is $10.80
Answer:
Sales tax = $0.8Total cost = $10.8Step-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.

5. Which two values are NOT solutions for x in the inequality 5x + 3 > 33?
a. 5
b. 6
c. 7
d. 8
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
A kitchen was remodeled and granite counter tops were installed A rectangular island in the kitchen now has a granite top measuring 8 ft by 5.3 inches. The density of granite is 2.7 kg/cm3.
don't forget to change to inches to feet and feet to centimeters.
how much does the counter top weigh in pounds? 1 kg= 2.2 pounds .
Answer:
Problem: if I correctly recall from my days of carving tombstones, the density of granite is not 2.7 kg/cm³, but 2.7 g/cm³
At 2.7 kg/cm³, the weight is 3,664,392 pounds
at 2.7 g/cm³, the true weight is 3664.39 pounds
Step-by-step explanation:
8 ft = 243.84 cm
5.3 inches = 13.46 cm
6 ft 2 in = 187.96 cm
volume = 243.84 cm x 13.46 cm x 187.96 cm = 616,901.01 cm³
616,901.01 cm³ × 2.7 kg/cm³ x 2.2 lb/kg = 3,664,392 pounds
2.7 g/cm³ = 0.0027 kg/cm³
616,901.01 cm³ × 0.0027 kg/cm³ x 2.2 lb/kg = 3664.39 pounds

In circle H with m \angle GHJ= 34m∠GHJ=34 and GH=11GH=11 units, find the length of arc GJ. Round to the nearest hundredth
Answer:
2.75unitsStep-by-step explanation:
Find the diagram attached
The length of an arc is expressed as shown;
[tex]L = \frac{\theta}{360} * 2 \pi r[/tex]
r is the radius = length of GH
r = GH = 11units
m<GHJ = 34 degree
Substitute the given parameters into the equation given;
[tex]L = \frac{\theta}{360} * 2 \pi r[/tex]
[tex]L = \frac{34}{360} * 2(3.14)(11)\\ L = \frac{34}{360} * 29.08\\L = \frac{988.72}{360}\\L = 2.75 units\\[/tex]
Hence the length of the arc to the nearest hundredth is 2.75units

Write 0.31% as a decimal.
Answer:
0.31% = 0.0031 in decimal form.
Step-by-step explanation:
Percent means 'per 100'. So, 0.31% means 0.31 per 100 or simply 0.31/100. If you divide 0.31 by 100, you'll get 0.0031 (a decimal number).
EXERCÍCIOS 01) Resolva. A Lino tinha R$430,00 para pagar as seguintes contas R$ 119,00 de energia elétrica, R$65,00 de água e RS97,00 de telefone para fazer algumas compras. Quanto the restou para fazer as compras
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

Nathaniel goes to a store an buys an item that costs xx dollars. He has a coupon for 40% off, and then a 7% tax is added to the discounted price. Write an expression in terms of xx that represents the total amount that Nathaniel paid at the register.
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.

Juicy's business Sweet Sauce is profiting at a rate 20,000 dollars per month. The starting balance in Sweet Sauce's account for 2020 was $50,000. How much money will be in Sweet Sauce's account after July 31st? Write an equation for this problem and answer the question. How much money will be in the account after 2 years?
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

Chemists use pH as a measure of acidity or alkalinity of a solution. It uses the concentration of hydrogen ions H+ in a logarithmic function. A chemist is studying the alkalinity of a hot spring near a volcano. The hydrogen ion concentration is increasing according to the function f(d) = (0.5 × 10–4)d, where d is the number of days. The function for pH is g(H+) = –log10(H+), where H+ is the hydrogen ion concentration of the solution. Which function shows the pH of the hot spring as a function of d? g(f(d)) = –log10(d) g(f(d)) = –d(log10(0.5 × 10–4)) g(f(d)) = –log10((0.5 × 10–4)d) g(f(d)) = –log10(d × 10–4)
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]
