Answer:
A2 = 120
A3 = 60
A5 = 60
A6 = 120
Step-by-step explanation:
Angle 1 and 2 are supplementary, so A2 = 180 - 60, which is 120.
Angle 1 and 3 are vertical angles, which are always the same measure.
Angle 5 is alternate interior angles with 3, which means it is also 60.
Angle 6 is alternate interior angles with 4, which means it is 120.

5. Which two values are NOT solutions for x in the inequality 5x + 3 > 33?
a. 5
b. 6
c. 7
d. 8
Answers
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 .
Answers
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

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.

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)
Answers
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]

Write 0.31% as a decimal.
Answers
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).
The light from the Cape Florida Lighthouse in Key Biscayne is visible for a distance of 15 mi. If the beam of light sweeps in an arc of 270°, what is the area covered by the beam?
Answers
Answer:
Area covered by beam = 530 mi² (Approx.)
Step-by-step explanation:
Given:
Radius = 15 mi
Arc angle = 270°
Find:
Area covered by beam
Computation:
Area of sector = [θ/360][π][r²]
Area covered by beam = [270/360][22/7][15²]
Area covered by beam = [0.75][3.1428][225]
Area covered by beam = 530 mi² (Approx.)
