Answer:

∠ TWV = 106°

Step-by-step explanation:

∠ TWV and ∠ SVW are same- side interior angles and are supplementary, thus

∠ TWV + ∠ SVW = 180°, that is

3x - 5 + 2x = 180

5x - 5 = 180 ( add 5 to both sides )

5x = 185 ( divide both sides by 5 )

x = 37

Thus

∠ TWV = 3x - 5 = 3(37) - 5 = 111 - 5 = 106°

To estimate the total number of games during the baseball tournament, round the daily games (16) to the nearest ten (20) and multiply by the number of days (10), resulting in an estimated 200 games.

To estimate the number of baseball games during Lansing's annual baseball tournament, we can round the larger number to the nearest ten and then multiply it by the number of days in the tournament. The larger number, representing the number of games per day, is 16. Rounding 16 to the nearest ten gives us 20. As the tournament lasts 10 days, we calculate the total by multiplying these two numbers.

Estimated total number of games = Rounded number of games per day x Number of days in the tournament
Estimated total number of games = 20 x 10
Estimated total number of games = 200 games.

Answer:

B

Step-by-step explanation:

y = 6(x^2-6x+9)-2

y = 6x^2-36x+54-2

y = 6x^2-36x+52

The standard form of the given quadratic equation y=6(x-3)²-2 is y = 6x² - 36x + 52 after expanding the squared binomial and simplifying.

The student has asked for the standard form of the quadratic equation y=6(x-3)²-2. The standard form of a quadratic equation is ax² + bx + c = 0. To rewrite the given equation in standard form, expand the squared binomial and simplify:

So, the standard form of the given equation is y = 6x² - 36x + 52.

Answer:

3/4x-6=42

x=64

Step-by-step explanation:

Let the number of students be x hence 3/4 of this number will be 3/4x

Since the number was 42 if they were 3/4x less six, it means minus six hence

3/4x-6=42

Therefore, the equation will be

3/4x-6=42

Solving the equation

3/4 x=42+6=48

3/4x=48

X=62

Answer:

First Step: separate x^2 from -16

Second Step: add -16/25 to the other side.

Step-by-step explanation:

x^2 - 16/25 = 0

^^ this might be easier if you separate x^2 and -16

First Step-

so rewrite the problem as x^2/25  -16/25 = 0

then...

Second Step-

add -16/25 to the other side. This makes it: x^2/25 = 16/25

Continuation-

Now, you can multiply 25 on both sides to cancel it out.

so you have x^2 = -16

Answer:

18

Step-by-step explanation:

It is 18 because 14 x 2 equal 28 so that would mean you need one stick to make 2 pizzas. Then you divide 36 by 2 and get 18

Pat needs 18 sticks of pepperoni to make 36 pizzas

The unitary method is a method in which you find the value of a unit and then the value of a required number of units

According to the problem,

Using unitary method,

To make 28 pizzas Pat needs 14 sticks of pepperoni.

∴ To make 1 pizza, Pat need  [tex]\frac{14}{28}[/tex] sticks of pepperoni

∴ To make 36 pizzas, Pat needs [tex]\frac{(14)(36)}{28}[/tex]  sticks = 18 sticks of pepperoni

So, Pat needs 18 sticks of pepperoni to make 36 pizzas

Step-by-step explanation:

Well, let’s use a cancelling technique.

We know that 10, 24, 26 is just 5, 12, 13 multiplied by 2. So that works! And 50, 120, 130 is just 5, 12, 13 multiplied by 10. So that also works! And 15, 36, 39 is just 5, 12, 14 multiplied by 3. Therefore 2 is our answer...

60% of 94 is calculated by multiplying 94 by 0.60, which results in 56.4.

To find 60% of 94, you will multiply 94 by 0.60. Performing this calculation:

60% of 94 = 0.60 * 94

0.60 * 94 = 56.4

So, 60% of 94 equals 56.4.

Answer:

The first one is 15.75 lbs or 15 3/4. The second one is 28 years old. The third one is$9.90 each t-shirt

Step-by-step explanation:

For the first one you multiply 18 by 14 and you get 252. Then there is 16 ounces in a pound so you divide by 16. Then you get 15.75. So that is your answer. The 2nd one you take 84 and multiply it by 1/6 then since she is twice the age of her sister you multiply by 2. so it would look like: 84 times 1/6= 14

14 times 2 = 28. So she is 28 years old. The third one you take 32 and subtract it by 12.20. You will be left with 19.8. Then both t-shirts cost the same so you would divide 19.8 by 2. You are left with 9.9. So the answer is $9.90. Sorry this took 10 minutes.

Answer:

15.75lb of hotdogs

Amy is 28 years old

she paid $9.90 for each shirt.

Step-by-step explanation:

1) we multiply the number of packages by how much each package weighs. which gives us 252ounces we can then convert ounces to pounds by multiplying by 0.0625pounds/1ounce which gives us 15.75lb

2) amy's age is her fathers age devided by 6 which gives us fourteen. we know Hannah's age is twice Amy's age, so we multiply 14 by two, 14X2=28

3) we subtract the money Rose spent on the poster from the overall amount rose spent. $32.00-$12.20=$19.80. so we know Rose spent $19.80 on t-shirts, since we also know she bought two equaly priced t-shirts we can devide $19.80 by 2, $19.80/2=$9.90, therfore, she spent $9.90 on each shirt.

Answer:

The length of the hypotenuse of this triangle is 150√2 mm.

Step-by-step explanation:

Consider the square ABCD shown in the image below.

The sides are 150 mm each.

All the angles of a square are 90°.

Now The square is folded in half along the diagonal BD.

The angles A, B and D are:  45°, 45° and 90°.

The hypotenuse of the right angled triangle is BD.

Compute the length of BD using the pythagoras theorem as follows:

[tex]BD^{2}=AB^{2}+AD^{2}\\=150^{2}+150^{2}\\=2\times 150^{2}\\BD=\sqrt{2\times 150^{2}}\\=150\sqrt{2}[/tex]

Thus, the length of the hypotenuse of this triangle is 150√2 mm.

Answer:

8,760

Step-by-step explanation:

If Kaylah is reading 142 words in one minute, there is 60 minutes in an hour.

therefore,

142 x 60 = 8,760

Answer:

8520 minutes

Step-by-step explanation:

To solve, make a proportion

142 words in 1 minute, and x words in 60 minutes (1 hour).

142/1=x/60

Cross multiply

142*60=1*x

8520=x

Another way to solve is to know that each hour has 60 minutes, and she can read 142 words in 1 minute. So, we can just multiply 60 and 142.

60*142=8520

The value of [tex]'d'[/tex] is 7.83.

Step-by-step explanation:

Given:

[tex]d+(-5.004)=2.826[/tex]

We need to solve for [tex]'d'[/tex] .

Solution:

[tex]d+(-5.004)=2.826[/tex]

Now we know that;

By the rule  of Addition and subtraction for positive and negative numbers

when a positive and negative signs are met then the result is negative.

So we can say that;

[tex]d-5.004=2.826[/tex]

Now Adding both side by 5.004 using addition property of equality we get;

[tex]d-5.004+5.004=2.826+5.004\\\\d= 7.83[/tex]

Hence The value of [tex]'d'[/tex] is 7.83.

Answer:

13.5 mi/h

Step-by-step explanation:

The average speed of the car can be written as

[tex]v=\frac{d}{t}[/tex]

where

d = 4.8 miles is the total distance covered

[tex]t=6\cdot (8 min) = 48 min \cdot \frac{1}{60}=0.8 h[/tex] is the  time elapsed

So the average speed is

[tex]d=\frac{4.8}{0.8}=6 mi/h[/tex]

We also know that the total time consists of 6 8-minutes interval, and the speed of the car decreased by 3 mi/h each interval.

Calling [tex]v_1[/tex] the average speed in the 1st interval, we have:

[tex]v_2=v_1-3\\v_3=v_1-6\\v_4=v_1-9\\v_5=v_1-12\\v_6=v_1-15[/tex]

The average speed in each interval can be written as [tex]v_i=\frac{d_i}{t}[/tex], where [tex]d_i[/tex] is the distance covered in each interval and [tex]d_i = 8 min =0.133 h[/tex] is the duration of each interval, so we can write

[tex]\frac{d_2}{t}=\frac{d_1}{t} -3 \rightarrow d_2 = d_1 -3t[/tex]

And similarly,

[tex]d_3=d_1-6t\\d_4=d_1-9t\\d_5=d_1-12t\\d_6=d_1-15t[/tex]

Since the total distance is [tex]d=d_1+d_2+d_3+d_4+d_5+d_6[/tex], we have:

[tex]d=6d_1 - 3t-6t-9t-12t-15t=6d_1-45t[/tex]

And since we know that

d = 4.8 miles

and t = 0.133h, we can find d1:

[tex]d_1=\frac{d+45t}{6}=\frac{4.8+(45)(0.133)}{6}=1.8 mi[/tex]

So the average speed in the first 8-minute interval is:

[tex]v_1=\frac{d_1}{t_1}=\frac{1.8}{0.133}=13.5 mi/h[/tex]
