In ΔOPQ, q = 83 inches, p = 80 inches and ∠P=70°. Find all possible values of ∠Q, to the nearest degree

Answers

Answer 1

Answer:

77.12°

Step-by-step explanation:

Given that:

In triangle OPQ

∠P=70°

line q = 83 inches

line p = 80 inches

To find ∠Q; we use the since rule:

[tex]\dfrac{Sin \ Q}{q} = \dfrac{Sin \ P}{p}[/tex]

[tex]\dfrac{Sin \ Q}{83} = \dfrac{Sin \ 70}{80}[/tex]

[tex]Sin \ Q= \dfrac{Sin \ 70 \times 83}{80}[/tex]

[tex]\text{Sin \ Q= 0.9749}[/tex]

[tex]Q=Sin ^{-1}( 0.9749)[/tex]

[tex]\mathbf{Q = 77.12^0}[/tex]

Problem 1

ax^2+bx+c is standard form(x+p)(x+q) is factored form

There's not much to say about these. You'll just have to memorize the terms. Note with standard form that the exponents decrease as you move from left to right (2,1,0).

===============================================

Problem 2

Other names for zeros are:

A) x interceptsD) solutions

The term "root" is also applicable here.

===============================================

Problem 3

We set each piece equal to 0 and solve for x. This is the zero product property

f(x) = (x-2)(x+4)

0 = (x-2)(x+4)

(x-2)(x+4) = 0

x-2 = 0 or x+4 = 0

x = 2 or x = -4

The two x intercepts are located at (2,0) and (-4,0)

Answer: Choice C

===============================================

Problem 4

In the last problem, we found the two roots were x = 2 and x = -4

I'll let p = 2 and q = -4.

Average the roots to get (p+q)/2 = (2+(-4))/2 = -2/2 = -1

This is the x coordinate of the vertex. So h = -1

Plug this into the function to find k, which is the y coordinate of the vertex.

k = f(h)

k = f(-1)

k = (-1-2)(-1+4)

k = (-3)(3)

k = -9

The vertex is located at (h,k) = (-1, -9)

This is another way of saying the vertex is when x = -1 and y = -9

If you are looking for the value of x, use the Pythagorean Theorem.

x² = 58² - 40² = 1764

x = √1764 = 42

Answer: 42cm

Step-by-step explanation:

Using the formula

(Hypotenuse^2)= (Opposite^2) + (Adjacent^2)

Hypotenuse= 58cm

Opposite= 40cm

Adjacent= x

Therefore

(58^2)= (40^2) + (x^2)

3364= 1600 + x^2

3364-1600= x^2

1764= x^2

x= 1764^1/2

x= 42

Adjacent= 42cm

An arithmetic sequence has a 2nd term equal to 3 and 10th term equal to -13.
Find the term of the sequence that has value -93?​

Answers

Answer:

n = 50

Step-by-step explanation:

Let a be the first term and d be the common difference.

An arithmetic sequence has a 2nd term equal to 3 and 10th term equal to -13.

[tex]a_n=a+(n-1)d[/tex]

According to the given condition,

[tex]a_2=3\\\\a_{10}=-13[/tex]

or

[tex]a+(2-1)d=3\\\\a+d=3\ ...(1)\\\\a+(10-1)d=-13\\\\a+9d=-13\ ...(2)[/tex]

Subtract equation (1) from (2).

a+9d-(a+d) = -13-3

8d = -16

d = -2

Put the value of d in equation (1).

a+(-2) = 3

a = 3+2

a = 5

Now,

[tex]a+(n-1)d = -93\\\\5+(n-1)(-2)=-93\\\\5-2n+2=-93\\\\7+93=2n\\\\2n=100\\\\n=50[/tex]

So, 50th term has the value of -93.

Why might algebra tiles not be a good tool to use to factor x2 + 18x + 80? Explain.

Answers

Step-by-step explanation:

Algebra tiles would not be a good tool to use to factor the trinomial because you would need to drag an x-squared tile, 18 x-tiles, and 80 plus tiles. That is a total of 99 tiles. It would take a lot of time to drag that many tiles on the board and there might not be enough space to hold all of them. You would also need to determine how to arrange all those tiles to make a rectangle. Since 80 is a multiple of 10, you might recognize that 10 and 8 are the factors that add to 18, which would give you the values to use in the X method.

There are a lot of tiles to drag onto the board.

You would need to create a rectangle from 99 tiles.

80 is a multiple of 10, so it has factors of 10 and 8, which add to 18.

Ai Mi went to the store to buy some chicken. The price per pound of the chicken is $3.50 per pound and she has a coupon for $2.50 off the final amount. With the coupon, how much would Ai Mi have to pay to buy 3 pounds of chicken? Also, write an expression for the cost to buy pp pounds of chicken, assuming at least one pound is purchased.

Answers

Answer:

$8 for 3 pounds

cost for p pounds: 3.50p - 2.50

Step-by-step explanation:

Cost of 3 pounds:

Original cost = Cost per pound x 3

= 3.50 x 3

= 10.50

Coupon = 2.50

Final cost = Original cost - Coupon

= 10.50 - 2.50

= $8

Cost of p pounds:

Original cost = Cost per pound x p

= 3.50 x p

= 3.50p

Coupon = 2.50

Final Cost = Original Cost - Coupon

= 3.50p - 2.50

A drink is made by mixing 650 ml of water with 150 ml of fruit juice.

What percentage of the drink is fruit juice?

can you please reply quickly?

Answers

○=> Correct answer :

[tex]\boxed{\color{hotpink}\tt18.75\%} [/tex] of the drink is fruit juice

○=> Steps to derive correct answer :

Quantity of water in a drink = 650 ml

Quantity of fruit juice in a drink = 150 ml

Total quantity of both items in the drink :

[tex] =\tt 650 + 150[/tex]

[tex] \color{plum}=\tt 800 \: ml[/tex]

Thus, the total quantity of both items in the drink = 800 ml

Let the percentage of of fruit juice in the drink be x%.

Which means :

[tex] = \tt\frac{x}{100} \times 800 = 150[/tex]

[tex] = \tt \frac{x \times 800}{100} = 150[/tex]

[tex] =\tt \frac{800x}{100} = 150[/tex]

[tex] =\tt 8x = 150[/tex]

[tex] =\tt x = \frac{150}{8} [/tex]

[tex]\hookrightarrow\color{plum} \bold{x = 18.75\%}[/tex]

Then, the percentage of water in the drink :

[tex] = \tt100 - 18.75[/tex]

[tex] \color{plum}= \tt81.25\%[/tex]

Thus, the percentage of water in the drink = 81.25%

○=> Therefore :

▪︎Percentage of fruit juice in the drink = 18.75%

▪︎Percentage of water in the drink = 81.75%

18.75% is fruit juice

Examples:

1 hour = 60 minutes

1 minute = 60 seconds

1 km = 1000 m

We have,

To find out when the boy left school, we need to add 4 hours and 20 minutes to the time he arrived at school.

To add minutes, we need to make sure both times are in the same format. Let's convert the arrival time of 8:15 am to minutes:

So,

8:15am = 8 x 60 + 15 = 495 minutes

Now we can add 4 hours and 20 minutes:

495 + 4 x 60 + 20 = 735 minutes

So the boy left school at 735 minutes after midnight.

To convert this back to a time, we can divide by 60 to get the number of hours and minutes:

735 minutes / 60

= 12 hours (with 15 minutes remaining)

Therefore,

The boy left school at time 12:15 pm.
