Answer:

The angle A for the first question is equal to 43.6 degrees

Step-by-step explanation:

1st step:

[tex]\frac{sin\theta}{20} \times \frac{sin 90}{29}[/tex]

2nd step:

Take 20 to the other side.

[tex]sin \theta = \frac{20(sin90)}{29}[/tex]

3rd step:

Solve the right side and then take the inverse sin of the right side to get the value of theta and you get 43.6 degrees

[tex]\theta = 43.6[/tex]

Answer:f(x)=-3+4

g(x)=2

that means:f(x) is -3                                 AND

g(x) is 2.

Step-by-step explanation:

Answer:

solve for y   y= -2+x/2

solve for x   x=4+2y

Step-by-step explanation:

x-2y=4

+x    =4+x

  -2y = 4 + x  divide both sides by -2

   2         -2

      y=-2 + x/2

x-2y=4

 +2y=4+2y

 x  = 4+2y

Answer:

Formula for area of a circle;

A = πr^2

where pi is 3.14 in this case, and r is the radius squared

Plug in the actual values;

A = 3.14 x 11^2

A = 3.14 x 121

A = 379.94 square feet

Answer:

               [tex]\bold{\underline{a_n=18n-15}}[/tex]

Step-by-step explanation:

[tex]a_n=a_1+d(n-1)\\\\a_5=a_1+d\cdot4\\\\a_7=a_1+d\cdot6\\\\a_7-a_5=a_1+6d-(a_1+4d)=2d\\\\111-75=2d\\\\2d=36\\\\d=18\\\\\\a_1+18\cdot4=75\\\\a_1=75-72=3\\\\\\a_n=3+18(n-1)=3+18n-18\\\\\underline{a_n=18n-15}[/tex]

The solution of the [tex]\rm log(2t+4)=log(14-3t)[/tex] is 2.

It is given that the  [tex]\rm log(2t+4)=log(14-3t)[/tex].

It is required to find the value of  't'.

It is another way to represent the power of numbers and we say that 'b' is the logarithm of 'c' with base 'a' if and only if 'a' to the power 'b' equals 'c'.

[tex]\rm a^b=c\\\rm log_ac=b[/tex]

We have:

[tex]\rm log(2t+4)=log(14-3t)[/tex]

Taking  [tex]\rm log_1_0[/tex]  base and removing the log from both sides.

[tex]\rm 2t+4=14-3t\\\rm 5t=10\\\rm t=2[/tex]

Thus, the solution of the [tex]\rm log(2t+4)=log(14-3t)[/tex]  is 2.

Answer:

a+3p

Step-by-step explanation:

l=a+4p-1p

l=a+3p

Hope this helps :)

Answer:

l = a + 3(p)

explanation:

upper length:  a+ 4(p)

bottom length:  p + l

Therefore,

p + l = a+ 4(p)

l = a + 4(p) - p

l = a + 3(p)

Easy way to spot is to take the 4x term to the LHS.

[tex]y-4x = 8\\y-4x = 2[/tex]

You're required to find a quantity that is at the same time equal to both 8 and 2, which is obviously impossible.

There are two ways to figure this equation out.

Answer: O No solution

Way One - Graphing

     We can graph the two equations. Points of intersection represent a solution to the set.

-> See attached.

     Since there are no points of intersection, the answer is "O No solution"

Way Two - Analyzing the Equations

     We can see that both of these equations have a slope of 4. We then can set them both equal to the y-intercept to see if they will have solutions.

y = 4x + 8

 -> y - 4x = 8

y = 4x + 2

 -> y - 4x = 2

     Because 8 ≠ 2, but y - 4x = y - 4x, the answer is "O No solution"

Answer:

3/2

Step-by-step explanation:

Answer: 3/2

Step-by-step explanation: 12 and 8 can be reduced by dividing them by 4, so 12/8 can be simplified to 3/2.

Answer:

a) you need to plot a cross on the graph (with the pencil) in the right place:

(x-axis: 4, y-axis: 2600)

b) the older the car is, the lower its value. there is a negative correlation between the cars age and its value.

c) you need to draw a line of best fit on the graph. where the line is at 3 1/2 years, that is its estimated value. (my guess is around £3000)

Using compound interest, it is found that Gabriel was left with $6,255.

The balance, in compound interest, after t years, is given by:

[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]

In which the parameters are given as follows:

In the context of this problem, the values of these parameters are as follows:

P = 6000, t = 2, r = 0.04, n = 12.

The balance after two years is:

[tex]A(2) = 6000\left(1 + \frac{0.04}{12}\right)^{24}[/tex]

A(2) = 6499.

The balance after one year is:

[tex]A(1) = 6000\left(1 + \frac{0.04}{12}\right)^{12}[/tex]

A(2) = 6244.

The interest paid on the first year was:

A(1) - P = 6244 - 6000 = 244.

Hence the amount that he was left with is:

6499 - 244 = $6,255.

Answer:

2/14, 4/28, 5/35, 7/70 or just 2/14

Step-by-step explanation:

Multiply both the numerator and denominator of 1/7 by 2, to get 2/14, or 2:14

And multiply the numerator and denominator of 1/7 by 3, to get 3/21, or 3:21. So 2:14 and 3:21 are two ratios that are equal to 1:7.
