Answer:

73

Step-by-step explanation:

2x+x+53+88=360

Add up the numbers together.

3x+141=360

Subtract 141 from 360

3x=219

Divide 219 by 3

x=73

Answer:

9.4 miles

Step-by-step explanation:

We can assume that if these joggers run 8 miles north, consecutively 5 miles west, these lengths form legs of a right angle triangle, from which we have to determine the hypotenuse of the triangle provided it would lead to the shortest route possible;

Knowing this is a right angle triangle, let us apply Pythagorean Theorem to solve for the length of this hypotenuse, which we can assign as x;

8^2 + 5^2 = x^2 ⇒ square 8 and 5,

64 + 25 = x^2 ⇒ Combine like terms,

x^2 = 89 ⇒ Take square root on either side

Solution; Shortest Distance ⇒ length of 9.4 miles

Answer:

{5,6,10,12,15,18}

Step-by-step explanation:

X={5,6,10,12,15,18}

Y={6,10,12,15}

XUY={5,6,10,12,15,18}

You don't need to put a number more than once.

I'm going to assume that you are trying to find the volume of a rectangular prism.

Volume formula: V = lhw

V = 10*9*7

V = 90*7

V = 630

Therefore, the volume is 630mi³

Best of Luck!

Answer:

See explanation below

Step-by-step explanation:

In picture attached I manage to find one graph. Just follow the explanation of this, if your graph data is different than this.

According to the attached graph we can see that the line of the graph is beggining at 12. So we this, we can assume and say that the initial height of the swimmer is 12 ft.

The max height would be the maximum point in the graph where it reach the maximum height. In other words, the highest point of the line. since the beggining of the jump. As you can see in the graph, this is reached between 22 and 24 ft. So we can assume is around 23 ft. So the maximum height would be 23 ft

Finally the x-intercept, would be the point of the line where it reach the x-axis. In this case, it would be a point really close to 8. You can say it's about 7.8, or even the number 8 if you wish. In this case, let's say it's 7.8 the x-intercept

-x=-15-2 (u put the like terms together)

-x=-17 (u divide both sides by -1)

x=17

Answer:

lateral surface area is 160.14 square cm.

Total surface area is 273.16  square cm  

Step-by-step explanation:

Lateral surface area of cone is given by [tex]\pi rl[/tex]

where r is radius of cone

and l is slant height of cone.

l = 85 millimetres

we know that 10 millimetres is equal to 1 cm

Thus 85 millimetres is equal to 8.5 cm

Thus slant height(l) in cm is 8.5[tex]\pi rl\\=>\pi 6*8.5\\=> 3.14*51\\=>160.14[/tex]

we will use value of [tex]\pi[/tex] as 3.14

Diameter of cone = 12 cm

we know that radius is equal to half of Diameter

radius of given cone = 1/2 *Diameter = 1/2 * 12 = 6 cm.

Thus lateral surface area of cone is given by

[tex]\pi rl\\=>3.14*6*8.5\\=>153[/tex]

Thus, lateral surface area is 160.14 square cm.

Area of base of cone will be area of circular base

area of circle is given by [tex]\pi r^2[/tex]

Thus area of base is given below

[tex]\pi r^2\\=>3.14*6^2\\=>113.04[/tex]

area of base is 113.04 square cm

Total surface area of cone is sum of area of base and lateral surface area

Total surface area = 160.14+113.04 = 273.16  square cm.

Answer:

A.

Step-by-step explanation:

Given that point P partitions a directed line segment from A to B into the ratio 3:4, we are to determine how close P is to either A or B.

To do this, we take an example.

Let the length of line segment AB be 14 Units.

Since P divides AB in the ratio 3:4

Therefore, from the above, we can conclude that P will be closer to A as its distance from A is shorter than its distance from B.

The correct option is A.

Answer:

Point P partitions the directed line segment from A to B into the ratio 3:4. Will P be closer to A or B? Why?

A number line goes from point A to point B. A line is drawn from point A to point B.

Right Answer  A.)   P will be closer to A because it will be Three-sevenths the distance from A to B.  

Wrong Answer  B.)   P will be closer to A because it will be Four-sevenths the distance from A to B.

Wrong Answer C.)    P will be closer to B because it will be Three-sevenths the distance from B to A.

Wrong Answer D.)   P will be closer to B because it will be Four-sevenths the distance from B to A.

Answer: $5.5

Step-by-step explanation:

Here is the complete question:

L.B. Johnson Middle School held a track and field event during the school year. The chess club sold various drink and snack items for the participants and the audience. Altogether, they sold 486 items that totaled $2,673 a. If the chess club sold each item for the same price, calculate the price of each item. b. Explain the value of each digit in your answer to a using place value terms

Item sold = 486

Total amount = $2673

Price of each item = Total amount/items sold

= 2673/486

= $5.5

Each item costs $5.5.

5.5 = 5 units and 5 tenths.

The first number after the decimal point by the right is the tenths.

Answer:

answer is 60

Step-by-step explanation:

because if the angle is 60 degrees anywhere in the triangle means its an equilateral triangle making all the angles 60 degrees

Answer:

60 degrees

Step-by-step explanation:

Every Triangle has an angle of 180 degrees

so if we add all of the written angles which is 25 + 35 + 60 = 120

we take 180 degrees and subtract it with the previous answer (120)

180 - 120 = 60

Therefore it is 60 degrees

Answer:

7.5×1041.25×10−9 = 78,084.75 = 7.808475 x^10

Step-by-step explanation:

All four angles sum to 360 so the remaining two add to 360-180-20=160.  

7+9=16, 160/16=10, so we scale our ratio by 10, getting 70:90.

Answer: 70 degrees and 90 degrees

Answer:

7+9=16, 160/16=10, so we scale our ratio by 10, getting 70:90.

Answer: 70 degrees and 90 degrees

Step-by-step explanation:

Answer:

x intercept = -0.25

y intercept = 4

Step-by-step explanation:

  1.- remove parenthesis

y-3 = 1/2x +1

  2.- adjust to equal y

y = 1/2x +1 +3

y = 1/2x +4

  3.- guess values for x to try in the simplified equation.

x = -0.25 | y = 0

x = 0       | y = 4

x = 2       | y = 5

x = -2      | y = 3

x = 4       | y = 6

x = -4      | y = 2

  4.- graph all coordinates (x,y). Draw a line connecting each dotted coordinate.

Answer:

33.51

Step-by-step explanation:

The volume for finding a sphere is V= 4/3 x π x r ^3

(V=volume, r= radius)

V= 4/3 x π x r ^3

V= 4/3 x π x 2 ^3

2^3= 8

Calculator: 4 ÷ 3 x 3.14 (OR PI SYMBOL) x 8

ANSWER: 33.51

Answer:

3017.5 cm³

Step-by-step explanation:

The volume of a rectangular prism is V = l × w × h

Here the length is 14.2, the width is 12.5, and the height is 1

Plugging these into our formula we get V = (14.2)(12.5)(1) = 177.5 cm³

Since there are 17 CD cases stacked on top of each other, we will multiply our number by 17 which gives us (177.5)(17) = 3017.5 cm³

Answer:

Area of circle = πr²

New doubled area = πR² ( r ≠ R )

As it is double of older area :

πR² = 2πr²

R² = 2r²

R = √2r

Thus we have to multiply the radius to √2 to double its area

Answer:

137 toys

Step-by-step explanation:

You take the number of dogs = 15

and how many things each dog needs = a collar, bowl, and toy

and you multiply 15 by three to get the number of collars, bowls, and toys each dog needs. Then repeat this process and add all of your answers

Dog = 60

Cat = 88

Rabbit = 4

88 + 60 + 4 = 137

(If the collar, and bowls don't count as toys then just message me and I will redo the math for you.)

Answer:

5

Step-by-step explanation:

Raman have 72.75 M long string and he cut the string in pieces of equal length of 14.55 M long .

To find how many pieces he cut, we simply divide the length of the original piece of string by the length of the cut piece of string.

That is:

72.75 / 14.55 = 5

He can cut 5 pieces of string.

My reasoning is the mention of PHOTOPERIODISM. Photoperiodism means the reaction to length of a day or night cycle, since fall is the beginning of shorter days and longer nights, it is only reasonable that the answer is that THey bloom when the nights are longer.
