Answer:

 =  1 0

Step-by-step explanation:

Solve

1. Combine like terms

2  +  2 0  + 2  =  6 0

4  +  2 0  =  6 0

2. Subtract  20  from both sides of the equation

4  +  2 0  =  6 0

4  +  2 0  −  2 0  =  6 0  −  2 0

3. Simplify

4  +  2 0  −  2 0 =  6 0  −  2 0

4  =  6 0  −  2 0

4 =  6 0  −  2 0

4  =  4 0

4. Divide both sides of the equation by the same term

4x = 40

4x/4 = 40/4

5. Simplify

4x/4 = 40/4

x = 40/4

x = 40/4

x = 10

Step-by-step explanation:

Given:

In circle O, m∠R = 30.8°.

To find:

The m∠NOQ

Solution:

Central angle theorem: According to this theorem, the central angle is always twice of subtended angle on the same arc.

Angle NOQ and angle NRQ are on the same arc but ∠NOQ is the central angle and ∠NRQ is the subtended angle on the arc NQ.

Using central angle theorem, we get

[tex]m\angle NOQ=2\times m\angle NRQ[/tex]

[tex]m\angle NOQ=2\times m\angle R[/tex]

[tex]m\angle NOQ=2\times 30.8^\circ[/tex]

[tex]m\angle NOQ=61.6^\circ[/tex]

Therefore, [tex]m\angle NOQ=61.6^\circ[/tex].

hello

so these angles you can apply the "vertically opposite angles are equal" rule

angle "A" is vertically opposite to 138º so therefore angle "A" is 138º

angle "B" is verticall opposite to 42º so therefore angle "B" is 42º

Answer:

x = -1

y = 1

Step-by-step explanation:

x + 2y = 1     (Multiply this by -2)

2x + 5y = 3

-2x - 4y = -2

2x + 5y = 3

y = 1

x + 2y = 1

x + 2(1) = 1

x + 2 = 1

x = 1 - 2

x = -1

Answer:

x = -1

y = 1

Step By Step Explanation:

x + 2y = 1

2x + 5y = 3

let x become the subject. use one of the equation.

x = 1 - 2y

substitute into another equation

2(1 - 2y) + 5y = 3

expend the bracket

2 - 4y + 5y = 3

collect like terms

- 4y + 5y = 3 - 2

y = 1

substitute into one of the equation to find x

x + 2y = 1

x + 2 (1) = 1

x + 2 = 1

collect like terms

x = 1 - 2

x = - 1

[tex]x=\frac{13}{2}, y=\frac{51}{4}[/tex]

Step-by-step explanation:

Answer:

B.) 4 * 3 * 3

Step-by-step explanation:

Unit volume of cube = 48 unit³

Using the volume relation :

Volume = Length * width * height

V = l * w * h

To obtain the odd representation, we calculate the volume of the dimensions given in the option and select the option which does not yield a volume of 48 unit³

A.) 8 * 2 * 3 = 48 unit³

B.) 4 * 3 * 3 = 36 unit³

C.) 6 * 2 * 4 = 48 unit³

D.) 3 * 2 * 8 = 48 unit³

Hence, prism with dimension 4 * 3 * 3 cannot be one of Kyle's prism

Answer:

she had a perfect score in 1/8 of all tests

she had a perfect score in 4 tests

Step-by-step explanation:

Tamara earned an A in 5/8 of all the tests she took.

In 1/5 of the those tests she got an A, she had a perfect score.

1/5 of 5/8 is 1/5 * 5/8 which equals 5/40 which can be reduced to 1/8.

That means that in 1/8 of all tests she took she got a perfect score.

She took a total of 32 spelling tests.

1/8 of 32 = 1/8 * 32 = 32/8 = 4

Answer:

she had a perfect score in 1/8 of all tests

she had a perfect score in 4 tests

Answer:

20 days

Step-by-step explanation:

Subtract 1.5 gallons from 14 gallons to obtain the number of days the car will run without the warning light going on:  12.5 gallons.

Dividing this result by 0.6 gallons/day, we get

 12.5 gal

------------------- = 20.82 days.  Round this down to 20 days.  (We're not

 0.6 gal/day                                dealing in partial days.)

Option A) 4a

Answer:

66 cm (Option B)

Step-by-step explanation:

The formula for the circumference of a circle is C = 2πr, so plug the values into the formula.  The radius, (r) of a circle is one half of the diameter, so split 21 is half to get a radius of 10.5.  Use 3.14 for π.  

C = 2πr

C = 2(3.14)(10.5)

C = 6.28 × 10.5

C = 65.94

Rounded to the nearest unit, you get a answer of 66 cm.  

Hope this helps!  :)

The statement which says that the measure of ∠ABD = ¹/₂ ∠ABC. So, the correct option is C.

An angle bisector is defined as a ray, segment, or line that bisects a given angle into two equal angles. The word bisection or half means dividing one object into two equal or identical parts. In geometry, we usually divide triangles and angles by lines or lines that are considered bisectors.

A geometric bisector is a ray, line, or segment that divides a given angle into two equal parts. For example, the bisector of a 60 degree angle divides it into two 30 degree angles. In other words, split the angle into two smaller congruent angles.

For the given case,

Ray BD bisects ∠ABC into two equal angles ∠ABD and ∠DBC; which can be written as ∠ABD = ¹/₂ ∠ABC.
