a new machine with better technology produces 210 gel pens every 15 minutes what is the concept of the proportionality in the relationship between the number of gel pens and number of minutes

Answers

Answer:

p = 14t

Step-by-step explanation:

y = kx

The rate k = 210 ÷ 15 = 14 gel pens per minute

"p" is number of pens, "t" is number of minutes

p = 14t

The sum of two numbers is 72. The greater number is 8 more than the smaller
number. Which equation can be used to solve for the smaller number? (1 point)
1) x - (x + 8) = 72
2) x + (x + 8) = 72
3) x(x + 8) = 72
04) x(x – 8) = 72

Answers

Answer:

2

Step-by-step explanation:

So first you would set your two numbers as variables. Let y be the greater number and x be the smaller number. This means that our equation for y will be x + 8. Now all we need to do is add x and y. INSTEAD of using y, we will SUBSTITUDE with the equation for y, x + 8. Now our equation looks like

x + (x + 8) = 72

When x = 1, y= 2, z = 3, then find the value of the sum of 5x square , -2x cube y and 3y to the power 4

5(1)^2 = 5 -2(1)^3(2)= -4 3(2)^4 = 48
5 - 4 + 48= 49

The answer is 49

Answer:

1305

Step-by-step explanation:

Equation = [tex]( 5x )^{2} + ( -2x ^{3} )y + ( 3y )^{4}[/tex]

               = (5×1)² + {(-2×1)³}×2 + (3×2)⁴

               = (5)² + {-2}³×2 + (6)⁴

               = 25 + (-8)×2 + 1296

               = 25 + (-16) + 1296

               = 25 - 16 + 1296

               = 9 + 1296

               = 1305

Find the m∠ULE in the triangle below.

please

Answers

Answer:

m∠ULE = 60°

Step-by-step explanation:

To find the measure of ∠ULE we will use the property of exterior angle of a triangle.

Since, measure of an exterior angle of a triangle is equal to the sum of two opposite interior angles.

m∠LUR = m∠LEU + m∠ULE

109° = 49° + m∠ULE

m∠ULE = 109 - 49

             = 60°

Therefore, measure of angle ULE is 60°.

What specific measure of a geometric figure is shown in the image? A. A 55mm side length B. A 180 mm side length C. A 55° angle D. A 125° angle (It may be A or C but idk)

Answers

Answer:

A 55° angle is a specific measure of a geometric figure is shown in the image. Therefore, option 'C' is correct.

Step-by-step explanation:

As protectors normally have two sets of numbers going in opposite directions.

As it is clear from the figure that the protector as the '0 mark' is the bottom edge of the protractor, while the 'center point' of the protector is being placed on the vertex of the angle.

From the figure, it is also clearly visible if we are able to read the degrees where the other ray of the angle is crossing the protractor, the protector is showing the 55° angle.

Therefore, a 55° angle is a specific measure of a geometric figure is shown in the image. Therefore, option 'C' is correct.

Answer:  GM = 18

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

Explanation:

Focus on triangle HKL. This is a right triangle with the horizontal leg KL = 2. The vertical leg is the unknown side HK. The hypotenuse is HL shown by the single tickmark.

Triangle HKJ is also a right triangle. It shares the leg HK and the hypotenuse JH is congruent to HL as indicated by the single tickmark.

By the hypotenuse leg theorem, we can show that triangle HKL is congruent to triangle HKJ

From there, the corresponding pieces JK and KL must be the same length. So we can say JK = 2 because KL = 2.

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

Now use the segment addition postulate

GK = GJ + JK

GK = 7 + 2

GK = 9

Focus now on triangle GKH and triangle MKH. We can prove these are congruent triangles using the hypotenuse leg theorem. Here HK = HK as mentioned before; also, GH = HM due to the double tickmarks.

As you can probably guess by now, the hypotenuse leg theorem only applies to right triangles.

Since  triangle GKH is congruent to triangle MKH, we know that

GK = KM

Since GK = 9, this makes KM = 9.

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

Therefore,

GM = GK + KM

GM = 9 + 9

GM = 18
