∠RQS and ∠TQS are complementary with ∠TQS, so are 48°

a)

b)

Find QS first

Find QT next

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!  :)

z=80

step by step explanation:

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.

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

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

The area of the circle formula is useful for measuring the space occupied by a circular field or a plot. A circle is a closed plane geometric shape. The area of the circle with diameter 20 in is 100 π inches².

The area of the circle is defined as the region occupied by the circle in a two dimensional plane. The diameter of the circle is the line which divides the circle into two equal parts and radius is half of the diameter.

The unit of area of a circle is m², cm², etc. The equation used to calculate the area of the circle is:

Area of a circle = π × r²

Here radius = 10 inches

Then the area of circle is given as:

Area = π × 10 × 10 = 100 π inches²

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:

 =  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

Answer:

it will take around 4.5 weeks

Step-by-step explanation:

614 divided by 134 will give you 4.582

Answer:

4.6 weeks

Step-by-step explanation:

In the question, it stated that the plant grows at the rate of 134 inches per week. And we can get the proportion:

[tex]\frac{1 week}{134 inches}[/tex]

Now, if you want to get the number of weeks it takes to grow 614 inches, set up the proportion

[tex]\frac{x }{614 inches}[/tex]

with x representing the number of weeks we are trying to find.

Since the two fractions are proprtional - we assume that the plant will always grow at the same rate, then we can state:

[tex]\frac{x }{614 inches}[/tex] = [tex]\frac{1 week}{134 inches}[/tex]

Now, cross multiply and simplify:

134x = 614

x = 614/134

x = 4.6 (Weeks)
