Answer:

t = 2

Step-by-step explanation:

using the rule of logarithms

[tex]log_{b}[/tex] x = n ⇒ x = [tex]b^{n}[/tex]

given

[tex]log_{4}[/tex] (7t + 2) = 2 , then

7t + 2 = 4² = 16 ( subtract 2 from both sides )

7t = 14 ( divide both sides by 7 )

t = 2

= 9.896907

31 ≈ 30

65 ≈ 70

9.7 ≈ 10
9.896907 ≈

Answer:

a=21° b=70°

Step-by-step explanation:

a=21°(Vertically Opposite Angles)

b+110°=180° (linear pair)

b=180-110

b=70°

[please mark me brainliest]

Answer:

a = 21°

b = 70°

c = 89°

Step-by-step explanation:

angle of measure b and the angle of measure 110 are two supplementary angles

Then b + 110 = 180

Therefore b = 180 - 110 = 70°

angle of measure b and the angle of measure 21 are two opposite angles

Then a = 21

We Know that the sum of the interior angles of a triangle equal to 180

Then a + b + c = 180

Therefore c = 180 - a - b = 180 - 21 - 70 = 159 - 70 = 89°

Step-by-step explanation:

Given

Find [tex]a_{43}[/tex]

We know that

Appy this to the two known terms and find the first term and the common difference

Find the coomon difference

Find the first term

Now find the 43th term

Answer:

-98

Step-by-step explanation:

General form of an arithmetic sequence:

  [tex]a_n=a+(n-1)d[/tex]

where:

Given:

To find the 43rd term we need to construct an equation for the nth term.  To do this, find the first term and the common difference by substituting the given information into the general formula to create a system of equations that can be solved.

[tex]\begin{aligned} \underline{\textsf{Equation 1}}} \\ a_{21} & =-32 \\ \implies a+(20-1)d & = -32 \\a+20d & =-32 \end{aligned}[/tex]

[tex]\begin{aligned} \underline{\textsf{Equation 2}}} \\ a_{50} & =-119 \\ \implies a+(50-1)d & = -119 \\a+49d & =-119 \end{aligned}[/tex]

Subtract Equation 1 from Equation 2 to eliminate a:

[tex]\begin{array}{r l}a+49d & = -119\\- \quad a+20d & = -32\\\cline{1-2}29d & = -87\end{aligned}[/tex]

Solve for d:

[tex]\implies d=\dfrac{-87}{29}=-3[/tex]

Substitute the found value of d into one of the equations and solve for a:

[tex]\implies a + 20(-3)=-32[/tex]

[tex]\implies a=28[/tex]

Substitute the found values of a and d into the general formula to create an equation for the nth term:

[tex]\implies a_n=28+(n-1)(-3)[/tex]

[tex]\implies a_n=31-3n[/tex]

Finally, substitute n = 43 into the found formula to find the 43rd term of the sequence:

[tex]\implies a_{43}=31-3(43)=-98[/tex]

Answer: 41.

Step-by-step explanation: To find the mean of a data set, you first need to add all the numbers together.  It should look like this:

28 + 40 + 53 + 39 + 45 = 205.

The next step is to divide 205 by how many numbers you have in the data set.  In this case, you have 5 numbers in the data set.  Your work should look like this:

205 / 5 = 41.

Therefore, the mean of the data set is 41.

Answer:

280 in ^2

Step-by-step explanation:

Hi ok heres how I did this:

SA of rectangular prism: S = 2(lw + lh + wh)

SA of triangle top thing(whats it called???): Surface area = (Perimeter of the base × Length of the prism) + (2 × Base Area) = (S1 + S2+ S3)L + bh

So basically for the square part, the surface area is

2(4*4+4*12+4*12), or 224

For the triangle part, the surface area is

4+4+4, or 12*4+2*4, or 48+8, or  56

224+56=280

The thing is I don't know why it says round though. Theres a chance its incorrect if they want something with a decimal. Let me know.
