Answer 1

Answer:

x (23+12)= 280

Step-by-step explanation:

X=8

add 23 plus 12 which equals 35

then multiply 35 by 8

Hope it helps

Answer 2

Answer:

-x + 39 = 31

y is directly proportional to x.
When y = 30, x = 6
a) Work out an equation connecting y and x.
b) Work out the value of y when x=12

Answers

If y is directly proportional to x then y:x.
When y = 30, x = 6 then 30/6 = 5:1. Therefor for every 1x there is 5y vice versa. When x = 12, then y = 5 * 12 = 60.
Therefore y = 60 hence 60:12

What is m
A: 19°
B: 68°
C: 112°

Answers

Answer:

m<N=68

Step-by-step explanation:

opposite angles of the parallelogram are equal(or congruent):

4x+36=6x-2

6x-4x=36+2

2x=38

x=38/2=19

the sum of the angles of the parallelogram =360

4x+36=4(19)+36=112 angle P

6x-2=6(19)-2=112 angle M

let Q= N=x

2x+112+112=360

2x=360-224

2x=136

x=136/2=68

Suppose that a new employee starts working at ​$7.72 per hour and receives a 5​% raise each year. After time​ t, in​ years, his hourly wage is given by the equation y=$7.72(1.05)t. Find the amount of time after which he will be earning​ $10.00 per hour.

After what amount of time will the employee be earning​ $10.00 per​ hour?

Answers

Answer:

substitute 10 for y (y=10) and solve for t

2.17

Step-by-step explanation:

I think the equation is written wrong because assuming that his wage increases at the end of each year, the beginning of the first year wages should be 7.72, not 0.

Divide 750 into the ratio 2:3​

Answers

Answer:

300 : 450

Step-by-step explanation:

sum the parts of the ratio, 2 + 3 = 5 parts

Divide 750 by 5 to find the value of one part of the ratio

750 ÷ 5 = 150 ← value of 1 part of the ratio , then

2 parts = 2 × 150 = 300

3 parts = 3 × 150 = 450

Then 750 in the ratio 2 : 3 = 300 : 450

The required answer is 750 in the ratio 2 : 3 = 300 : 450.

What is Ratio?

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

We have to divide 750 into the ratio 2:3​

The ratio is given in the question

⇒ 2:3​

We can see that the sum of the parts of the given ratio as

⇒ 2 + 3 = 5 parts

Divide 750 by 5 to determine the value of one part of the ratio

So the value of 1st part of the ratio

⇒ 750 ÷ 5 = 150

Now, 2nd parts = 2 × 150 = 300

And, 3rd parts = 3 × 150 = 450

So, 750 in the ratio 2 : 3 = 300 : 450

Therefore, the required answer is 750 in the ratio 2 : 3 = 300 : 450.

Step-by-step explanation:

A right triangle is formed between the wall, the ground and the ladder.

The ladder is the hypotenuse , the wall and ground are the legs.

let h be the height of the wall, then using Pythagoras' identity

h² + 33² = 39²

h² + 1089 = 1521 ( subtract 1089 from both sides )

h² = 432 ( take the square root of both sides )

h = [tex]\sqrt{432}[/tex] ≈ 20.8 ft ( to the nearest tenth )

What is the perimeter of a quadrilateral with vertices at (5,2),
(10,2), (5,5), and (10,5)? PLZZ SHOW WORK AND RIGHT!

Answers

Answer:

16

Step-by-step explanation:

Draw a picture!

Length1 goes from (5, 2) to (10, 2)

since the y coordinate is the same

L1 = (10 - 5) = 5

Length2 goes from (5, 5) to (10, 5)

since the y coordinate is the same

L2 = (10 - 5) = 5

Width1 goes from (5, 2) to (5, 5)

since the x coordinate is the same

W1 = (5 - 2) = 3

Width2 goes from (10, 2) to (10, 5)

since the x coordinate is the same

W2 = (5 - 2) = 3

-----------------------

Perimeter

p = 5 + 5 + 3 + 3

p = 16

The perimeter of quadrilateral is 16 units.

What is quadrilateral?

A closed quadrilateral has four sides, four vertices, and four angles. It is a form of polygon. In order to create it, four non-collinear points are joined. Quadrilateral interior angle sums are always equal to 360 degrees.

Given coordinates,

(5,2), (10,2), (5,5), and (10,5)

let A, B, C, and D be the points of coordinates (5,2), (10,2), (5,5), and (10,5) respectively.

Length1 goes from (5, 2) to (10, 2)

since the y coordinate is the same

AB = (10 - 5) = 5

Length2 goes from (5, 5) to (10, 5)

since the y coordinate is the same

BC = (10 - 5) = 5

Width1 goes from (5, 2) to (5, 5)

since the x coordinate is the same

CD = (5 - 2) = 3

Width2 goes from (10, 2) to (10, 5)

since the x coordinate is the same

DA = (5 - 2) = 3

perimeter = sum of all sides

p = 5 + 5 + 3 + 3 = 16 units

Hence the perimeter is 16 units.

Well, if you round the the answer is about 3.5 gummy worms.

This is because 45 divided by 13 equals 3.46153846. That is a VERY long number so you obviously round to the nearest tenth which gives you 3.5. So in the end you would need about 3 and a 1/2 gummy worms to lay them end to end and have a total length of 45 inches. I hope this helps!! (Also that is one really big gummy worm. 13 INCHES??

Answers:

x = angle MLN = 35 degrees

angle FLJ = 55 degrees

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

Explanation:

This problem is fairly tricky if you're not sure what to look for. A slight clue is that they've marked a red point that strangely doesn't have a label on it. It's a fairly small point but it's definitely there if you look closely. While this point's location isn't exactly what we want, we're fairly close. Start at point L and draw a ray through the center point P. Ray LP will intersect the circle at point A, as shown in the diagram below.

From here, draw segments FA and MA. Now notice that inscribed angle LMF = 55 and inscribed angle FAL both subtend the same arc. The term "subtend" basically means "cut off". This arc that the inscribed angles subtend is minor arc FL. A minor arc is where you travel the shorter path around the circle, which indicates its measure is less than 180 degrees.

Since inscribed angles LMF and FAL subtend the same minor arc, this makes the inscribed angles to be congruent.

In short: angle FAL is 55 degrees

----------------------

Segment LA goes through the center P. Through Thales theorem, we know that inscribed angle LFA is 90 degrees. Consequently, we can determine that inscribed angle FLA is 90-55 = 35 degrees.

Segment JL is tangent to the circle, meaning that angle ALJ is 90 degrees. So angle FLJ is 90-35 = 55 degrees.

It's not a coincidence that angle FLJ, angle FAL, and angle LMF are the same measure.

----------------------

We found that angle FAL was 55 degrees. Applying Thales theorem again shows that angle MAF is 90 degrees. Therefore, angle LAM is 90-55 = 35 degrees.

Focus now on triangle LMA. This is also a right triangle (Thales Theorem). The upper acute angle we found was angle LAM = 35, so the lower acute angle is ALM = 55.

Then we can find angle MLN = (angle ALN) - (angle ALM) = 90 - 55 = 35

In short, angle MLN = 35 degrees

Similar to the previous section, it is not a coincidence that angles LFM, LAM and MLN are the same measure.

------------------------

As an alternative, since we know angle FLJ = 55, and angle FLM is 90 degrees, this means...

(angle FLJ)+(angle FLM) + (angle MLN) = 180

55 + 90 + angle MLN = 180

145 + angle MLN = 180

angle MLN = 180 - 145

angle MLN = 35 degrees

QPK divides the polygon and point Q is not on the vertex of the polygon.

Answer:

C. Stem-and-leaf plots are easier to make and and can contain more information than histograms. However, they are not very useful for large data sets

Step-by-step explanation:

A stem and leaf plot is a graphical presentation of quantitative data similar to an histogram. However, a stem and leaf plot retains and present the values of the original in the data set such that individual data values can be seen and can then be used to make analysis

The stem and leaf plot consists of a stem and a leaf  arranged in the order of place value, such that the numbers having a common highest place value are arranged on a row in a stem and leaf plot and therefore a stem and leaf plot is easier to make or construct than an histogram

However, it is very rare to find stem and leaf plots having more than 50 datasets or observations.
