billy scores 129 points in 6 games. how many points does he score per games

Answers

Answer: 21.5

Step-by-step explanation:

Answer:

x = 21 ½

or

x = 21.5

Step-by-step explanation:

x = number of games.

6x = 6 games.

Since billy scores 129 points in these 6 games, that would mean we can set up this equation:

6x = 129.

Now divide both sides by 6 to get x alone.

x = 21 ½

or

x = 21.5

Carla is 5 years old and Jim is 13 years younger than Peter. One year ago, Peter's age was twice the sum of Carla's & Jim's age. Find the present age of each one of them.

Carla: ________ Jim: ________ Peter: _______

Answers

Answer: Carla: 5, Jim: 6, Peter: 9

Step-by-step explanation:

Let c be Carla's age, j be Jim's age, and p be Peter's age.

We can set up equations.

We already know that c = 5

j + 13 = p

p-1 = 2(c - 1 + j - 1)

Combine like terms:

p - 1 = 2(c + j - 2)

Distribute:

p - 1 = 2c + 2j - 4

p + 3 = 2c + 2j

We can plug in the value of 5 for c.

p + 3 = 10 + 2j

2j + 7 = p

We can plug in j + 13 for p.

2j + 7 = j + 13

Combine like terms:

j = 6

Therefore, p = 6 + 13 = 9

Work out the value of the missing angle x.

Answers

Answer:

x = 5°

Step-by-step explanation:

Linear pair: a pair of adjacent angles formed when two lines intersect. The two angles are always supplementary and so their measures sum to 180°.

If the side of a polygon is extended, the angle formed outside the polygon is the exterior angle.  The sum of the exterior angles of a polygon is 360°.

Sum of exterior angles:

⇒ 45° + 90° + 25° + 90° + x° + (180° - 140°) + (180° - 115°) = 360°

⇒ 355° + x° = 360°

⇒ x = 5°

Lea drives for 4 hours at 65 km/h. Hanna drives 252 kilometers in 3 hours.
How far would Lea drive if she drove for 4 hours at the same speed as
Hanna?

Answers

Based on the calculations, the distance covered by Lea is equal to 336 kilometers.

Given the following data:

Lea's time = 4 hours.Lea's speed = 65 km/h.Hanna's distance = 252 kilometers.Hanna's time = 3 hours.

How to calculate speed.

Mathematically, speed is given by this formula;

[tex]Speed = \frac{distance}{time}[/tex]

Next, we would calculate Hanna's speed by using the above formula:

[tex]Hanna's\; speed = \frac{252}{3}[/tex]

Hanna's speed = 84 km/h.

For Lea's distance:

[tex]Distance = speed \times time\\\\Distance = 84 \times 4[/tex]

Distance = 336 kilometers.

Answer:

y' = 1 / sinxcosx

Step-by-step explanation:

Given :

y = sinx + cosx / sinx - cosx

Applying quotient rule :

y' = [(sinx - cosx)(cosx - sinx) - (sinx + cosx)(cosx + sinx)] / (sinx -

cosx)²

y' = [sinxcosx - cos²x - sin²x + sinxcosx - (sinxcosx + cos²x + sin²x + sinxcosx)] / (sinx - cosx)²

y' = 2sinxcosx - 2sinxcosx - 2cos²x - 2sin²x / (sinx -cosx)²

y' = -2(sin²x + cos²x) / (sinx - cosx)²

y' = -2 / (sinx - cosx)²

y' = -2 / sin²x - 2sinxcosx + cos²x

y' = -2 / -2sinxcosx

A photographer needs a frame for an 5 x 7 inch picture, such that the total area is 80 in2. Calculate the width of the frame.
(Note: The frame is the same width all the way around)

Which of the following quadratic equations would be used when solving this?

4x^2 + 12x = 45
4x^2 + 24x = 45
2x^2 + 24 = 45
2x^2 + 12x = 45

Answers

Answer:

4x^2 + 24x = 45

Step-by-step explanation:

Answer:

4x² + 24x = 45

Step-by-step explanation: mark me brainliest!

”The total area of the frame and picture needed by the photographer = 80 in²The size of the picture that will be in the frame = 5 × 7 inchThe length of the picture = 7 inchesThe width of the picture = 5 inchesLet x represent the width of the frame, we get;

The width of the total area = The width of the picture + 2 ×

The width of the frameTherefore, the width of the total area = 5 + 2·x

The length of the total area =

The length of the picture + 2 ×

The width of the frame

Therefore, the length of the total area = 7 + 2·xWe get;

The total area = Total length × Total width 

The total area = (5 + 2·x) × (7 + 2·x) 

We are given that the total area = 80, therefore, by transitive property of equality,

we have;(5 + 2·x) × (7 + 2·x) = 8035 + 10·x + 14·x + 4·x² = 804·x² + 24·x = 80 - 35 = 45∴ 4·x² + 24·x = 45

Therefore, the quadratic equation that can be used in solving for the width is 4·x² + 24·x = 45.”

If m = 5 and n = 3, evaluate 2m + 6n

Answers

The answer would be 28.

Because m=5 and n=3 we would substitute those values in the corresponding equation. So our new equation would be 2(5) + 6(3). From here we follow the rules of PEMDS (Parentheses, Exponents, Multiplication, Division, Subtraction [or addition if present]). Now we multiply our values and then add. 2×5 is 10 and 6×3 is 18. 10+18=28, thus giving us the answer of 28.

Answers

Answer:

You have to divide the diagram into 3 rectangles and add the cm

Step-by-step explanation:

suppose you have a table-like - diagram and you have to find the perimeter

first, you divide it into 3 rectangles like so.

second, you right 1st rectangle= 1cm,2cm

then continue with this method until done.

third, you add all the measurements and you get the answer

Answer:

The perimeter is 22cm

Step-by-step explanation:

So first we know that the top is 5cm, the two bottom parts are each 1cm, one of the insides is 2cm, and the right side is 4cm. So far that gives us a perimeter of 13cm. Now we need to find the unlabeled sides, so first (and it doesn't matter what side you start with) let's find the left side. Because the shape is symmetrical we can look across at the right side's measurement, and it will be the same measurement for the left side, 4cm. Next the right inside. Again, we can look to the left and we see that the left inside has a measurement of 2 cm, so the right inside will be the same, 2cm. Now for the bottom. We see that the top is 5cm, and if we were to fill in that empty space at the bottom, it would also be 5cm. We know that the two bottom pegs are each 1cm, so they're 2cm combined. If we were to fill in the rectangle, the bottom would equal 5cm. So 5-2 (for the 2cm of the bottom pegs), we get 3cm for that bottom unlabeled part. So if we add 13 to our new numbers 4, 3, and 2, we get a perimeter of 22cm.

The circumference of a circle is 19π m. What is the area, in square meters? Express your answer in terms of
π.

Answers

Answer:

A = 90.25pi sq m

OR = 361pi/4 sq m

Step-by-step explanation:

If the circumference is 19pi, then the diameter is 19.

C = pi•d

19pi = pi•d

19 = d

If the diameter is 19, then the radius is 9.5.

The radius is always half of the diameter.

Then we can find the area.

A = pi•r^2

=pi•9.5^2

=90.25pi

We don't often see a decimal number coefficient for pi. So as an improper fraction, 90.25 which is 90 1/4 is

(90×4)+1 over 4

= 361/4

Area = (361/4)pi

=361pi/4 sq meters

Answer:

AC = 14.0

Step-by-step explanation:

We know that this is a non-right triangle, so we must use either the law of sines or law of cosines to find AC.

We can find the measure of <C using 180 - (118 + 22) = 40

Since we only know one side and all the angles, we can use the law of sines:  [tex]\frac{a}{sin A}=\frac{b}{sin B}=\frac{c}{sin C}[/tex]

[tex]\frac{24}{sin 40}=\frac{AC}{sin 22}[/tex]

What is 9 times 5 /8? as a mixed number? somebody please help me find the answer!

Step-by-step explanation:

9 = 9/1

so 9 x 5/8 = 9/1 x 5/8

you could quickly make it 45/8 or make it 9x5/1x8

45/8 is improper so you have to see which multiple of 8 is the highest without exceeding the numerator

40 is the closest and it is 8x5 so 5 will be the integer.

there are 5 leftover so 5 is also the numerator

and the denominator stays 8 as there is no further simplifying

Which equation form is the best to find the y-intercept?

Answers

Hi! I hope you're enjoying your day!

The best equation form is Slope-Intercept form (y=mx+b), where the letter m stands for the slope of the line and the letter b stands for the y-intercept of the line (where the graph touches the y-axis).

Why is Slope-Intercept the best form?

Because if you know y=mx+b, and you know what every variable means (m & b), then all you have to do is look at the equation and determine the y-intercept.

Example:

Suppose we have the following equation:

           [tex]\bold{y=0.7x-6}[/tex]

What is the y-intercept of this line?

Hint: Look at the equation.

That's right. The y-intercept is -6.

Hence, the best equation form is

[tex]\boxed{\boxed{\bold{Slope-Intercept\:Form}}}[/tex]

Hope everything is clear.
