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:

They should leave Carlo's house by 4:20 PM

Step-by-step explanation:

The movie starts at 8:10 pm, they want to arrive 20 minutes before the movie starts

20 minutes before 8:10 pm = 7:50 pm.

Hence, they should arrive by 7:50 pm

Duration of their activities before the movie is calculated as:

They will bowl for one hour and dinner will take 1 hour and 15 minutes. Travel time is 20 minutes to the bowling alley, 45 minutes ta the restaurant, and ten minutes to the theater.

: 1 hour + 1 hour 15 minutes + 20 minutes + 45 minutes + 10 minutes

= 2 hour 15 minutes + 75 minutes

= 2 hour 15 minutes +1 hour 15 minutes

= 3 hours 30 minutes in total.

The time they are meant to leave is calculated as:

7:50 pm - 3 hours 30 minutes

= 4:20pm

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)

Answer:  A)  f(x) = (x − 2)^2(x + 1)(x − 3)      

Step-by-step explanation: The graph shows the zeros to be -1, +2 (multiplicity 2), and +3.

When b is a zero, (x-b) is a factor. Then the factors of the function shown are ...

 f(x) = (x -(-1))·(x -2)·(x -2)·(x -3)

 f(x) = (x -2)^2(x +1)(x -3)

Answer:

p = 1

Step-by-step explanation:

2/5 + p = 4/5 + 3/5p

2/5 + p = 3p/5

2/5 + p = (4 +3p)/5

2 + 5p = 4 + 3p

5p = 4 + 3p - 2

5p = 3p + 2

5p - 3p = 2

2p = 2

p = 1

Answer:

Step-by-step explanation:

option B

Complementary angles add up to 90°

m∠A + m∠B = 90

30 + 2x + 10 = 90

       2x + 40 = 90

To find the value of x, we have to isolate x. To isolate x, first we have subtract 40 from both sides.

2x = 90 -40

2x = 50

Now, divide both sides by 2

x = 50/2

x = 25°

∠B = 2x + 10

      = 2*25 + 10

    = 50 + 10

∠B = 60°

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.

Answer:

a store is charged $5.50 each for calculators and a delivery of $25 for the order. If stores sells the calculators for $8 each, how many calculators must be sold to produce a profit of at least $80?

Step-by-step explanation:

Cost minus the charge which is 8 dollars minus 5.50 is the difference in which you divide 80 by it. 8-5.50= 2.5.     80 divided by 25 = 32. Hope this is the answer you're looking for.

Answer:

t₁ = 14

d = -2

Step-by-step explanation:

Given :-

t₆ = 4

t₁₀ = -4

To Find :-

t₁ and d

Solving :-

t₆ = t₁ + 5d = 4   -(1)

t₁₀ = t₁ + 9d = -4 -(2)

(2) - (1)

4d = -8

d = -2

t₁ + 5(-2) = 4

t₁ = 14

Solution :-

t₁ = 14

d = -2

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:

Step-by-step explanation:

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"
