1. The cost of 4 hates is $29.68. What is the unit price?


2. Jess types 625 words in 6 minutes. How many words can Jess type per minute?

Answer:

60 degrees

Step-by-step explanation:

I see 3 lines in the graphic.

1 horizontal line that gets crossed by 2 other lines - one at a 25 degree angle (and that line ends at the crossing point), and one at 60 degrees.

so, above and below the horizontal line, the line with 60 degrees and x degrees is the same line.

and therefore, as per the laws of crossing lines, the angles above and below the crossed line must be the same. they are just left-right mirrored.

therefore, x must be the same as the diametrically opposing angle above the horizontal line. and that is 60 degrees.

Answer:

68.50 in

Step-by-step explanation:

first we are given the width and the length for the rectangle and so we know that 4 × 5x + 7 = 128

so we would now solve for x:

4 × 5x + 7 = 128

= 4 × 5x = 121

= 20x = 121

= x = 6.05

now we can plug in 6.05 for x and find the perimeter:

5(6.05) + 4 = 34.25

5(6.05) + 4 = 34.25

34.25 + 34.25 = 68.50

Answer: 3(r-2)

Step-by-step explanation: found it online

Solution :

Tan 25° =  C4/BC

=> 0.466 = CF/60

=> C4 = 27.96

A4² = AC²  + C4²

AC² = 60² + 40² = 5200

CF² = 781.76

4F² =  5200 +  781.76

=> AF² =5981.76

=> A4 = 77.3

length A4  = 77.3  cm

Answer

If Christina's age is = x

Aaron's age is = x + 6

Jeo's age = 3(x + 6 )

So, the sum of their ages can be write as,

[tex]x + x + 6 + 3(x + 6) \\ x + x + 6 + 3x + 18 \\ 5x + 24[/tex]

Also, they have given that the sum of their ages is 149

Therefore we can write a equation as,

[tex]5x + 24 = 149[/tex]

Now let's solve this and find the age of Christina

[tex]5x + 24 = 149 \\ 5x = 149 - 24 \\ 5x =12 5 \\ \frac{5x}{5} = \frac{125}{5} \\ x = 25[/tex]

Aaron's age is

[tex] x+ 6 \\ 25 + 6 \\ = 31[/tex]

Joe's age is

[tex]3(x + 6) \\ 3(25 + 6) \\ 3 \times 31 \\ = 93[/tex]

Hope this helps you.

Step-by-step explanation:

If he digs at a rate of [tex]1~2/3[/tex] feet every hour, and he needs [tex]2~1/2[/tex] hours, we want to find [tex](2~1/2)/(1~2/3)=(5/2)/(5/3)=(5*3)/(5*2)=3/2=\boxed{1~1/2}[/tex] feet.

Answer:

∠p, ∠q, and ∠r are all 40°

Step-by-step explanation:

ARQ is a triangle so the sum of the interior angles must equal 180°

48 + 52 = 100

180 - 100 = 80°

This means that the last angle, 2p = 80°

If 2p = 80, then ∠p = 40° (divide by 2)

PQR is also a triangle which means PR is a straight line

The angle next to 2p is going to be 100, because 2p was 80 and angles on a straight line add to 180° (180 - 80 = 100)

∠r = ∠p because they are alternate angles (in the sideways Z shape), 40°

∠q can be found by doing:

180 - (∠PAQ + ∠r)

= 180 - (100 + 40)

= 180 - 140

= 40

Answer:

A = S square (s^2)

we know that A = 1296 square inches, then,

[tex]\sqrt{1296} = \sqrt{s^{2}} \\[/tex]      we square both sides and cancel out the square on the right                side. We get:

36 = s

The length of the sign is 36 inches.

Answer: 3.1

Step-by-step explanation:

Firstly, let's put 2/8 as a decimal. If we simplify 2/8, it would be 1/4. And what is the decimal of 1/4? 0.25

Now that we've got our decimals it would be easier to calculate.

12.4 * 0.25 = 3.1

Answer:

f(x) = 7/6

Step-by-step explanation:

First off, hello! This is my explanation to the provided answer,

You can use the slope formula, (or simply graph the points), y2 - y2 / x2 - x1.

This would give you: 1 - 8 / -2 - 4, meaning that you would get the answer: 7/6 as the slope.

Hope this helps, if you have any more questions please ask.

Answer by greenestamps(9721) About Me  (Show Source):

You can put this solution on YOUR website!

These are three very different problems. The rules of the forum are one problem per post. Please follow those rules in the future.

(1) Certainly guess and check is the easiest way to solve this problem, since you know the three ages are whole numbers. But you should be able to get to the solution with very few if any wrong "guesses" by making your guesses logically.

The product of the three ages is a multiple of 10, and therefore a multiple of 5; since all three ages are in the teens, one of them has to be 15. Then 4590/15 = 306.

You could do guess and check again from there. However, if you note that both the other ages have to be greater than 15, and you know the last digit of the product has to be "6", then the only possible pair of ages is 17 and 18. And indeed 17*18 is 306.

ANSWER: The ages are 15, 17, and 18.

(2) Here is an informal solution method using logical reasoning.

Take away the "extra" $90 that the jacket costs; you are left with a jacket and a hat that each cost the same, and the total is now $100-$90 = $10. That means each of them costs $5. Now add those extra $90 back on to the price of the jacket.

ANSWER: The jacket costs $95; the hat costs $5.

(3) Melody picks a number: Call it x.

She doubles the number: It is now 2x.

She squares are result: It is now (2x)^2 = 4x^2.

She divides the square by 3: It is now 4x^2/3.

She subtracts 30 from the quotient: It is now 4x^2/3-30.

The number she ends up with is 18.

Solve the equation that says 4x^2/3-30 = 18:

4x%5E2%2F3-30+=+18

4x%5E2%2F3+=+48

4x%5E2+=+144

x%5E2+=+36

x+=+6 or x+=+-6

ANSWER: The two possible starting numbers are 6 and -6. We get two possible answers because of the step where she squares the number.

Answer:

68

Step-by-step explanation:

x + x = 136

2x = 136

x = 136 / 2

x = 68

Answer:

• This triangle is isosceles hence two angles are equal.

• But, the sum of two interior angles are equal to the exterior angle.

[tex]{ \rm{x + x = 136 \degree}} \\ \\ { \rm{2x = 136 \degree}} \\ \\ { \boxed{ \rm{ \: \: x = 68 \degree \: \: }}}[/tex]

Answer:

The equation of a line passing through the points (2, 3) and (4, 6) is 3x - 2y = 0.

Step-by-step explanation:

Answer:

y = 5x + 8

m = 5

Step-by-step explanation:

ok so perpendicular means negative reciprocal of the slope so the original slope of the line is -1/5x so the negative reciprocal is 5 (5/1 and the negative undos the negative so it's positive) so now we will use the point (-2, -2) and plug that into the slope intercept form (y = mx+b)

so -2 = 5(-2) + b

5 • -2 = -10 and u add that to the other side so b = 8 so the answer is y = 5x + 8! hope this helps!

Answer:

y = -5/7(x) - 3/7

Step-by-step explanation:

1. We're already given the value of m in y = mx + b: -5/7. So, our equation looks like this so far: y = -5/7(x) + b.

2. To solve for b, the y-intercept, we use this formula: [tex]b = y_1 - m * x_1[/tex]

3. Now that we know the values of m and b, the equation looks like this: [tex]y = -\frac{5}{7}x -\frac{3}{7}[/tex].

Therefore, the answer is [tex]y = -\frac{5}{7}x -\frac{3}{7}[/tex].
