Answer:

  21.4  

Step-by-step explanation:

For this problem, you only need to know that the hypotenuse (x) is the longest side of the triangle. The only answer choice longer than 20 is ...

  x = 21.4

__

If you want to actually go through the numbers, you know that ...

  Cos = Adjacent/Hypotenuse

  cos(21°) = 20/x

  x = 20/cos(21°)

  x ≈ 21.4

Answer:

X=2.1 cm

Step-by-step explanation:

24 divided by 6= 4

the bigger triangle is 4 times larger. so you would divide 8.5 by 4 which is 2.1.

Hope this helps!! Also I sorry if I got the answer wrong. I haven't done this type of math in years.

Answer:

interior angle of a heptagon = 900 degrees

900 = 4x + (3x + 60)

840 = 7x

840/7 = 120

X = 120

120 X 4 = 480

120 X 3 = 360

480 + 360 + 60 = 900

4 angles = 120 degrees each

3 angles = 140 degrees each

The number of red cells are 4 and the number of blue cells are 8. Then the correct option is C.

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

In the grids, there are 12 square box.

Let R be the red and B be the blue.

R + B = 12   ...1

R / B = 1/2  ...2

By solving equation 1 and 2, we have

R + 2R = 12

      3R = 12

        R = 4

Then  

4 + B = 12

     B = 8

Then the correct option is C.

Answer:

x = 168

Step-by-step explanation:

A hexagon's total interior angles sums up to be 720, so what you have to do is just subtract.

x = 720-(84+128+150+103+87)

x = 168

Answer:

The Miami Dolphins had 3 touchdowns and 3 field goals.

Step-by-step explanation:

It is given that During their last game, the Miami Dolphins scored 6 times, for a total score of 30 points. They scored 7 points for each touchdown and 3 points for each field goal.

We need to write and solve the system of equations to find the total touchdowns and field goals scored.

Let x represents the number of touchdowns.

Let y be the number of field goals.

It is given that the Miami Dolphins scored 6 times

[tex]x+y=6[/tex]

[tex]x=6-y[/tex]....(1)

They scored 7 points for each touchdown and 3 points for each field goal.

The total score is 30 points:

[tex]7x+3y=30[/tex] ...(2)

Put the value of x from equation (1) into equation (2).

[tex]7( 6-y)+3y=30[/tex]

[tex]42-7y+3y=30[/tex]

[tex]-4y=30-42[/tex]

[tex]-4y=-12[/tex]

[tex]y=3[/tex]

Put y = 3 in equation 1.

[tex]x=6-3[/tex]

[tex]x=3[/tex]

Hence, the Miami Dolphins had 3 touchdowns and 3 field goals.

Answer:

The 2 numbers = 81 and 83

Step-by-step explanation:

As, one number = x

The other, because it's an even number and consecutive = x + 2

So the larger numbef here is x + 2

And they are saying 3 times x + 2 plus x = 330

So let's solve!

3 times x + 2 = 3(x+2) = 3x + 6

So we will add it to x = (3x + 6) +(x) = 4x + 6

So they are saying the sum of them will be 330

So, 4x + 6 = 330

4x = 330 - 6

4x = 324

x = 324/4

x = 81

So x is the first number = 81

And the second is x + 2 = 81 + 2 = 83

So the 2 numbers are 81, 83

Lets check!

3 times the bigger number = 83 x 3 = 249

We will add it to 81 and we will get 330

So, 249 + 81 = 330

So the answer is right

Answer:

Weight in Kilograms = 0.8 Kilograms

Weight in grams = 800 grams

Step-by-step explanation:

Tyler has a baseball bat that weighs 28 ounces.

a) Weight in Kilograms

From the question:

1 kilogram = 35 ounces

Hence:

35 ounces = 1 kilogram

28 ounces = x kilogram

Cross Multiply

35 × x = 28 × 1

x = 28/35

x = 0.8 kilograms

b) Weight in grams

1 kilogram = 1000 grams

0.8 kilogram = x

Cross Multiply

x = 0.8 × 1000 grams

x = 800 grams

Answer:

Step-by-step explanation:

On this one you would eliminate the ones that are negative or that go into a negative. Which would be A,C, and E. The rest that are left are zero or positive. B for example is a zero because eventually there will be no candle. D would be the same in some way, the students will eventually leave the school. Finally F, the temperature would be increasing.

Answer - B,D,F

Answer:

a=5.1

Step-by-step explanation:

Isolate the variable by dividing each side by the factors that don't contain the variable. Hope this helps! :)

The value of a, if The expression 2.4x − 3.9y − 1.2x + ay is equivalent to 1.2x + 1.2 y is 5.1.

A finite combination of symbols that are well-formed in accordance with context-dependent principles is referred to as an expression or mathematical expression.

Given:

2.4x−3.9y−1.2x+ay is equivalent to 1.2x+1.2y,

2.4x − 3.9y − 1.2x + ay = 1.2x + 1.2y

Simplify the above expression as shown below,

2.4x − 1.2x + ay - 3.9y = 1.2x + 1.2y

1.2x + y(a - 3.9) = 1.2x + 1.2y

As the expression is equivalent, compare the expression as shown below,

a - 3.9 = 1.2

a = 1.2 + 3.9

a = 5.1

Thus, the value of a is 5.1.

Answer: [tex]2\dfrac14\text{ hours}[/tex]

Step-by-step explanation:

Given:  It takes a robin [tex]1\dfrac12[/tex] hours to fly 45 miles.

[tex]1\dfrac12=\dfrac32[/tex]

Speed of robin= [tex]\dfrac{distance}{time}=\dfrac{45}{\dfrac32}[/tex]

[tex]\dfrac{45}{3}\times2= 15\times2= 30\text{ miles per hour}[/tex]

A robin can fly 10 miles per hour faster than a blue jay. It

Speed of Blue jay = Speed of robin - 10 miles per hour

= 30 miles per hour - 10 miles per hour

= 20 miles per hour

Time taken to cover 45 miles = [tex]\dfrac{45}{20}=\dfrac{9}{4}=2\dfrac14\text{ hours}[/tex]

Hence, it will take [tex]2\dfrac14\text{ hours}[/tex]  by a blue jay to fly that same distance.

The temperature at 2 PM will be  x +16°F

Temperature is a phrase used to describe the degree of heat or cold on any scale, including Fahrenheit and Celsius. A thermometer is used to determine temperature. It is calibrated using different temperature scales that historically defined themselves using different reference points and thermometric substances.

The most popular scales are the Celsius scale, also known as "centigrade," with the unit °C, the Fahrenheit scale, with the unit °F, and the Kelvin scale, with the unit K. The latter is primarily used for scientific research and is the primary temperature scale specified by the International System of Units (SI).

Let temperature at 6 AM be x°F

Time difference between 2 PM and 6 AM:

Δt = 14 -6

 = 8 hour

increase in temperature after every 1 hour = 2°F

increase in temperature in 8 hour will be:

ΔT = 2 * Δt = 2*8 = 16°F

Temperature at 2 PM will be = x + ΔT

                                                = x +16°F
