Step-by-step explanation:

Answer 2

Answer:

D

Step-by-step explanation:

The answer is D because you want to add the same variables together (6x+7x) to simplify. and you would leave the 5 alone because it does not have the same variable.

the ratio of the measures of the angles of a triangle is 1:2:3 find the measures of each angle​

Answers

Given:

The ratio of the measures of the angles of a triangle is 1:2:3.

To find:

The measures of each angle​.

Solution:

Let the measure of angles be x, 2x and 3x respectively.

We know that, sum of all the interior angles of a triangle is 180 degrees by the angle sum property.

Using angle sum property, we get

[tex]x+2x+3x=180^\circ[/tex]

[tex]6x=180^\circ[/tex]

Divide both sides by 6.

[tex]x=\dfrac{180^\circ}{6}[/tex]

[tex]x=30^\circ[/tex]

Now,

First angle: [tex]30^\circ[/tex]

Second angle: [tex]2(30^\circ)=60^\circ[/tex]

Third angle: [tex]3(30^\circ)=90^\circ[/tex]

Therefore, the measure of all the angles are 30°, 60° and 90° respectively.

Answers

Answer: 29

Step-by-step explanation: 180-146= 34-5 29.

Answer:

[A] 29

Explanation:

Equation: 180 = 146 + (x + 5)

The line adds up to 180, so we need to find what x is

180 = 146 + (x + 5)

Switch Sides

146 + (x + 5) = 180

Remove Parenthesis

146 + x + 5 = 180

Group Like Terms

x + 146 + 5 = 180

Add: 146 + 5 = 151

x + 151 = 180

Subtract 151 From Each Side Of Equation

x + 151 - 151 = 180 - 151

x = 29

What is the equation of the line –3x–2y=30 in slope-intercept form?



Enter your answer in the box.

Answers

Answer:

y = - 1.5x - 15

Step-by-step explanation:

Step 1:

- 3x - 2y = 30         Equation

Step 2:

- 2y = 3x + 30        Add 3x on both sides

Step 3:

y = - 1.5x - 15      Divide 2 on both sides

Answer:

y = - 1.5x - 15

Hope This Helps :)

Answer:   y = - 1.5x - 15

Step-by-step explanation:

First, we will add 3x to both sides of the equation.

-2y = 3x + 30

Next, we will divide 2 on both sides of the equation.

y = -1.5x - 15

Answer -  y = -1.5x - 15

The two triangles are similar.
Solve for h.
Give an exact answer.

Answers

Answer:

[tex]\frac{1}{1.6} = \frac{h}{7.2}[/tex]  ( since they're similar, they are proportional to each other)

1 (7.2) = h (1.6) (set the two up as a proportion and then cross multiply)

7.2 = 1.6h (divide both sides by 1.6)

h = 4.5 m (this is the answer)

An office supply store sells 12 rolls of tape for $29.88. At that rate, which proportion could be used to solve for c, the cost of 36 rolls of tape?

Answers

Answer:

$89.64

Step-by-step explanation:

First, you want to find your unit rate.

To do that, simply just divide what you know (cost/amount):

29.88/12

= 2.49

This means that one role of tape costs $2.49.

Now that we know that, you can simply just solve for value "c":

c = 2.49(36)

c = 89.64

What is parallelogram?

In two-dimensional geometry, it is a plane shape having four sides, in which two pairs of sides are parallel to each other and equal in length. The sum of all angles in a parallelogram is 360°.

The two opposing sides are equal and parallel. The opposing angles line up evenly. The following or neighboring angles are extra. Every angle will be at a right angle if one of the other angles is even.

A parallelogram has equal opposite angles (or congruent) Angles that are next to one another are said to be consecutive (that means they add up to 180 degrees)

The true identities are,

AB=CD

m∠ABC + m∠BCD = 180°

Thus, statements D and E are true about ABCD.m∠ABC + m∠BCD = 180° and AB=CD.

Answer:

D

Step-by-step explanation:

When it's talking about going to the infinity, negative or positive, it just means when the line is going down with no end on the graph (in regards to y because that would be a vertical amount aka up and down). When it's in regards to x, it's the same concept except if it's negative infinity for x, it's on the left side. And if it's positive infinity for x, it's on the right side.

Write an equation of the line that passes through (1, -8) and is parallel to the line y = -3x - 7

Answers

Answer:

the desired new equation is y = -3x - 5

Step-by-step explanation:

The desired equation of this new (parallel) line has exactly the same form as the given line y = -3x - 7.  Only the y-intercept will be different.  

Starting with y = -3x - 7, replace x with the x-coordinate of the given point (1, -8) and y with the y-coordinate.  We get:

-8 = -3(1) + C, where C is the new y-intercept and is to be determined.

Then C = -5, and the desired new equation is y = -3x - 5.

Answers

Answer:

0.2047

0.2377

Step-by-step explanation:

1.

What we have here is a binomial distribution

Probability p = 0.12

N = number of students in the class = 30

Probability of finding 4 left handers

P(x = 4) = 30C4 x (0.12)⁴ x (0.88)²⁶

= 27405 x 0.00020736 x 0.03602047835

= 0.2047

2.

This is also a binomial distribution

N = 10 p = 0.65

P(of 6 knowledgeable fans)

= 10C6 x (0.65)⁶ x (0.35)⁴

= 210 x 0.0754189 x 0.01500625

= 0.2377
