Solve 3* = 42. Round to the nearest hundredth.
Answer:
[tex]x = 3.40[/tex]
Step-by-step explanation:
Given
[tex]3^x = 42[/tex]
Required
Find x
[tex]3^x = 42[/tex]
Take Log of both sides
[tex]Log\ 3^x = Log\ 42[/tex]
Apply log rule
[tex]xLog\ 3 = Log\ 42[/tex]
Make x the subject
[tex]x = \frac{Log\ 42}{Log\ 3}[/tex]
[tex]x = \frac{1.6232}{0.4771}[/tex]
[tex]x = 3.4022[/tex]
[tex]x = 3.40[/tex] --- approximated

Answer:
24°
Step-by-step explanation:
[tex]r \degree = 180 \degree - (34 + 122) \degree \\(vertical \: \angle s) \\ \\ r \degree = 180 \degree - 156 \degree \\ \\ r \degree = 24 \degree \\ \\ r = 24[/tex]
Answer and Step-by-step explanation:
The answer is 24 degrees.
We see the angle 34 and 122. To find that angle in between, we subtract those numbers from 180.
180 - 34 - 122 = 24 = r
By the vertical angles theorem, r is equal to 24.

What is the area of this composite figure? A figure is comprised of 2 rectangles. The first rectangle has a length of 10.5 centimeters and width of 15.5 centimeters. The second rectangle has a length of 18 centimeters and width of 11.5 centimeters. 135 centimeters squared 207 centimeters squared 249 centimeters squared 279 centimeters squared
A is the correct answer i didnt the test
The area of the composite figure is A = 369.75 cm²
What is the Area of a Rectangle?The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle
Area of Rectangle = Length x Width
Given data ,
Let the area of the rectangle be A
where A = A₁ + A₂
Now , area of first rectangle A₁ = 10.5 x 15.5
A₁ = 162.75 cm²
And , area of second rectangle A₂ = 18 x 11.5
A₂ = 207 cm²
So , A = 162.75 cm² + 207 cm²
A = 369.75 cm²
Hence , the area of figure is A = 369.75 cm²

Find the missing parts of the triangle. Round to the nearest tenth when necessary or to the nearest minute as appropriate.
a = 8.1 in.
b = 13.3 in.
c = 16.2 in.
A = 31.9°, B = 52.8°, C = 95.3°
No triangle satisfies the given conditions.
A = 29.9°, B = 54.8°, C = 95.3°
A = 27.9°, B = 54.8°, C = 97.3°
I think it might be B
Answer:
Step-by-step explanation:
Use the Law of Cosines to find the measure of angle A from the lengths of the sides.
A = arccos[(b²+c²-a²)/(2bc)] ≅ 29.9°
B = arccos[(a²+c²-b²)/(2ac)] ≅ 54.8°
C = 180 - A - B = 95.3°

find the factors of each number. Write the common factor ( CF ) and then state the greatest common factor ( GCF) .
Given:
Two numbers are 12 and 21
To find:
The factors of 12 and 21, then find the common factor and the greatest common factor.
Solution:
Two numbers are 12 and 21. The prime factors of these two numbers are
[tex]12=2\times 2\times 3[/tex]
[tex]21=3\times 7[/tex]
From the above factorization, it is clear that the factor 3 is common in both. So,
Common factor (CF) = 3
Only 3 is common in factorization of both. So,
Greatest common factor (GCF) = 3
Therefore, the common factor is 3 and the greatest common factor is also 3.

A vessel without a lid has the shape of a cylinder. The height of the vessel is 1.5 m, and the diameter of the base represents 40% of the height. Determine if 1 kg of paint is enough to completely paint the vessel inside and out, if it is known that for 1 square meter of surface 150g of paint is consumed.
Answer:
Yes, 1 kg of paint is enough to completely paint the inside and outside surfaces of the vessel.
Step-by-step explanation:
For the given vessel without a lid,
diameter = 0.4 x 1.5
= 0.6 m
radius = [tex]\frac{diameter}{2}[/tex] = [tex]\frac{0.6}{2}[/tex]
= 0.3 m
Total external surface area of the vessel = 2[tex]\pi[/tex]rh + [tex]\pi[/tex][tex]r^{2}[/tex]
= [2 x [tex]\frac{22}{7}[/tex] x 0.3 x 1.5] + [[tex]\frac{22}{7}[/tex] x [tex](0.3)^{2}[/tex]]
= 2.8286 + 0.2829
= 3.1112
Total external surface area of the vessel is 3.1112 square meter.
Total internal and external surface area = 2 x 3.1112
= 6.2224 [tex]m^{2}[/tex]
But for 1 square meter, 150 g of paint is consumed. Thus;
for 6.2224 [tex]m^{2}[/tex] = 6.2224 x 150 g
= 933.36 g
Thus, 6.2224 [tex]m^{2}[/tex] of area would require 933.36 g of paint.
So that,
[tex]\frac{933.36}{1000}[/tex] = 0.93336 kg
Therefore, 1 kg of paint is enough to completely paint the inside and outside surfaces of the vessel.
