Answer:

x = 27

Step-by-step explanation:

∠AB is 180° as it is a straight line. Then, we have 3 angles here, 2 known and 1 unknown. These angles have to add up to 180° as they just divide ∠AB into 3 sections. Solve for x with the given information:

[tex]36+90+2x=180\\126+2x=180\\2x=54\\x=27[/tex]

Answer:

x = 27

Answer:

arc RS = 72°

Step-by-step explanation:

The measure of the inscribed angle SQR is half the measure of its intercepted arc RS , then

2x + 14 = [tex]\frac{1}{2}[/tex] (6x + 6) = 3x + 3 ( subtract 2x from both sides )

14 = x + 3 ( subtract 3 from both sides )

11 = x

Then

RS = 6x + 6 = 6(11) + 6 = 66 + 6 = 72°

Answer: its an enlargement and when it enlarges A goes up 6 and moves to the right 3 spaces P stays the same b also moves to the right 6 spaces

so in conclusion answers are

A'=(8,5)

B'=(-2,10)

Answer:

$374

Step-by-step explanation:

She makes $30 per hour, today she worked 5 hours =) 30.5=150 ($)

28% of $800 = 28/100 . 800 = 224 ($)

Total: 150+224 = 374 ($)

Answer:

15 stones

Step-by-step explanation:

1) It is easier to convert to one unit. So i chose to convert everything to inches.

1 foot = 12 inches

10 feet = 120 inches

2) we then simply divide the size of the stones to see how much we need to cover the path

120/8 = 15 stones  

Answer:

  a) 6

  b) 5

  c) 5

Step-by-step explanation:

In this context, "of" means "times."

a) 1/5 of 30 = 1/5×30 = 30/5 = 6

b) 1/4 of 20 = 1/4×20 = 20/4 = 5

c) 1/3 of 15 = 1/3×15 = 15/3 = 5

Answer:

RS = 6

Step-by-step explanation:

The line joining the midpoints of 2 sides of a triangle is half the length of the third side, that is

RS = [tex]\frac{1}{2}[/tex] AB = [tex]\frac{1}{2}[/tex] × 12 = 6

8 boys, x girls, 4 pencils each, total number of pencils 52.

The equation can be 4(8+x) = 52

So lets solve:

4(8+x)=52

Divide 4 on both sides:

8 + x=52 / 4

8 + x = 13

Subtract on both sides:

x = 13 - 8

x = 5

There are 5 girls in the class.

Now lets solve to double check:

4(8+5)=52

4(13)=52

52 = 52

Yes!

This means that there are 5 girls in the class.

I hope this helps! :)

Taking into account the definition of equation, there are 5 girls in the class.

An equation is defined as an equality established between two expressions, in which there may be one or more unknowns that must be solved.

In other words, an equation is the equality between two algebraic expressions connected through the equals sign in which one or more unknown values, called unknowns, appear in addition to certain known data.

Each equation has two members, and these are separated by using the equal sign (=), which in turn each of them are made up of terms.

The unknowns, that is, the values ​​to be found, are represented by letters.

The equality between the two algebraic expressions is only verified for certain values ​​of the unknown.

In this way, the solution of an equation means determining through certain procedures the value that satisfies it.

A class has 8 boys and x girls. Each student has 4 pencils. The total number of pencils the students is 52.

An equation that models this situation is:

4×(8+x)= 52

It is considered that:

Solving in this case:

8 +x= 52÷4

8 +x= 13

x= 13 -8

x= 5

Finally, there are 5 girls in the class.

Answer:

skew

skew

parallel

parallel

Step-by-step explanation:

First see the below figure to understand parallel and skew lines

As you can see parallel lines lie on the same plane

skew lines lie on different plane and do not intersect

1)AB and GF

AB lies on ABCD plane

GF lies on EFGH plane

and they will never meet / intersect

so skew

2)DH and BF

DH lies on ADHE plane

BF lies on BCGF plane

they seem parallel but they are on different plane, so skew

3)EF and HG

EF and HG both lie on the same plane EFGH

and they both are parallel

4)for this see the second picture

both these planes are parallel

Hope this helps!

Think of a vertical number line. The positive values count down as we move down this number line. The negative numbers count up, so to speak, as we move down the number line. So we have -1, -2, -3, ... as we move down. This indicates that -5 is not smaller than -7.

Answer:

3 1/8

Step-by-step explanation:

16 bags = 50 m

1 bag = 50/16

1 bag = 25/8

1 bag = 3 1/8 ( due to mixed fraction )

so the cloth needed to make one bag is 3 1/8 m

Step-by-step explanation:

Answer:

Below!

Step-by-step explanation:

The slope is 1. The unit rate is $4.75/min If the graph of a proportional relationship passes through the point (1 , R) then r equals the slope and the unit rate. $4.75 per min.

The slope of the graph resembles the unit rate.

The unit rate is the amount it cost per minute.

The graph passes through the point (1, 3.40), which means it is at x = 1, the rate is $4.75.
