Answer 1
Answer:
[tex]\frac{11}{8}[/tex]
Stepbystep explanation:
1) To find tan m = 1/2 on a calculator, you need to take the inverse to find m.
[tex]tan^{1}[/tex](1/2) is about 26°.
So, m = 26°
2) To find tan n = 6 on a calculator, you also need to take the inverse.
[tex]tan^{1}[/tex](6) is 80, which is positive 280°. (360°  80° = 280°)
n = 280°
3) SO, the exact value of tan(m + n) would be tan(26° + 280°), which is tan(306°).
tan(306°) is about 1.376.
The closest answer to 1.376 is the third answer choice, which is 11/8.

Find the mass of a cube that has a density 2.7 g/ml and measures 3 cm on each side
Answers
Answer:
m = 72.9 grams
Stepbystep explanation:
Given that,
The density of a cube, d = 2.7 g/mL
Side of the cube, l = 3 cm
The volume of the cube is :
[tex]V=l^3\\\\V=(3)^3\ cm^3\\\\V=27\ cm^3[/tex]
Since, 1 mL = 1 cm³
Mass per unit volume is equal to the density of an object.
[tex]m=d\times V\\\\m=2.7\ g/mL\times 27\ mL\\\\m=72.9\ g[/tex]
So, the mass of the cube is 72.9 grams.
Answer:
m = 72.9 grams

Write the first four terms of the sequence whose general term is given.
an = 3n+2
Answers
Answer:
5,8,11,14.
Stepbystep explanation:
The general term of the sequence is given by :
[tex]a_n=3n+2[/tex]
We need to find the first four terms of the sequence.
Put n = 1
[tex]a_1=3(1)+2=5[/tex]
Put n = 2
[tex]a_2=3(2)+2=8[/tex]
Pu n = 3
[tex]a_3=3(3)+2=11[/tex]
Put n = 4
[tex]a_4=3(4)+2=14[/tex]
Hence, the first four terms of the sequence are 5,8,11,14.

10 years
Stepbystep explanation:
Let x be the number of years we need to add
We want same to be 5 times older than his niece
50 +x = 5(2+x)
Distribute
50+x = 10 +5x
Subtract x from each side
50+xx = 10+5xx
50 = 10+4x
Subtract 10
5010 = 4x
40 = 4x

Write an inequality to compare the numbers 12.7 and 12 3/4
Answers
Answer:
12.7 <12 3/4
Stepbystep explanation:
12 3/4=12.75
12.7=12.70
12.70<12.75
12.7< 12 3/4
The inequality that compares both 12.7 and [tex]12\frac{3}{4}[/tex] is
[tex]12.7 < 12\frac{3}{4}[/tex]
Given :
Two numbers that are decimal and fraction
12.7 and [tex]12\frac{3}{4}[/tex]
Convert mixed fraction in to improper fraction
[tex]12\frac{3}{4}=\frac{12 \cdot 4+3}{4} =\frac{51}{4}[/tex]
Now we write this fraction in decimal form so that we can compare easily
[tex]\frac{51}{4} =12.75[/tex]
Now we compare 12.7 and 12.75
12.7 is less than 12.75
[tex]12.7 < 12\frac{3}{4}[/tex]

Answers
Answer:
a. x
b. 35
c. 45
d. y
Explanation:
a. The independent variable is not dictated by any other variable. x is the only variable here that fits that description is x.
b. A coefficient is a constant that multiplies any variable. 35 multiplies x, so it is a coefficient.
c. A constant is a number that cannot change and isn't a coefficient. 45 cannot be changed.
d. The dependent variable is dictated by other variables. y is dictated by x, so it is the dependent variable.
45 is the starting charge, meaning that that is the default cost for any plumbing before they've started working. 35x means that it's 35 dollars per hour (x.) The 35 dollars per hour obviously depends on how many hours the person has worked. Y is the total cost of everything together.
The independent variable is x, since it depends on nothing.
The coefficient is 35, since it's the number before x.
The constant term is 45, since that number can't change.
The dependent variable is y, since it depends on x for the sum.
