Answer:

55

Step-by-step explanation:

here's the working out i did

The measure of arc AC from the given circle is 55 degree. Therefore, option C is the correct answer.

The angle subtended by an arc at the center is twice the angle subtended at the circumference. More simply, the angle at the center is double the angle at the circumference.

Given that, in the circle, diameter AB is parallel to chord CD.

Here, measure of arc CD is 70°.

Since, AB is diameter, than the measure of arc AB is 180°.

Now, 180°-70°=110°

So, measure of arc AC = measure of arc CD = 110°/2

= 55°

Therefore, option C is the correct answer.

Answer:

B. d(t) = 9t; 23.22 ft

Step-by-step explanation:

m= minutes  

2.58*m  

2.58*9=23.22

The snail will travel 23.32 feet in 9 minutes.

Answer

As given

A snail travels at a rate of 2.58 feet per minute.

First write a rule to describe the function.

Let a is denoted the distance.

t is the time

Thus the function becomes

a =  2.58 × t

a = 2.58t

This denoted the distance travelled in t time.

Second how far will the snail travel in 9 minutes .

Put t = 9 mintues in the above equation.

a =  2.58 × 9

a = 23.22 feet

Therefore the distance travelled in 9 mintues are  23.22 feet .

2.58m

So, in m you write the minutes.

2.58*9=23.22 feet per minute

Answer:

D. y = 6x – 5​

Step-by-step explanation:

Red: 6x – 2y = 10

Blue y = 6x – 5​

The line {y} = 6x - 5 will intersect the line 6x – 2y = 10 exactly at one point.

The general equation of a straight line is -

y = mx + c

where -

{m} is the slope of the line.

{c} is the {y} - intercept.

Given is to find the equations that will intersect the graph of (6x - 2y = 10) exactly once.

The equation of a straight line given is -

6x - 2y = 10

2y = 6x - 10

y = 3x - 5

The lines -

{y} = 3x- 10

{y} =3x - 5

{y} = 3x – 1

are parallel to the line {y} = 3x - 5 as their slopes are equal. So, these 3 equations will not intersect.

Therefore, the line {y} = 6x - 5 will intersect the line 6x – 2y = 10 exactly at one point.

Answer:

-30 5/6

Step-by-step explanation:

You are adding two negative numbers, so add their absolute values and make the answer negative.

-28 1/3 + (-2 1/2) =

= -(28 1/3 + 2 1/2)

We add the absolute values 28 1/3 and 2 1/2. We need a common denominator for the fractions. The LCD of 2 and 3 is 6.

= -(28 + 2 + 1/3 + 1/2)

= -(30 + 2/6 + 3/5)

= -(30 5/6)

= -30 5/6

Answer:

he drove 233 miles.......

Step-by-step explanation:

since theta is opposite divided by hypotenuse.

so sine 31=3÷AD

Therefore AD=3÷sine 31

thus AD=5.8248

in nearest hundredth, it will be 5.82 units

The length of AD to the nearest hundredth is 5.82 units.

Trigonometric ratios are particular measurements of a right triangle, which is a triangle having a 90° angle. The legs are the two sides that make up the right angle in a right triangle, while the hypotenuse is the third side that is across from the right angle.

Types of trigonometric ratios:

The six trigonometric ratios are

Calculation for the side AD:

In triangle ACD,

Angle CAB = 34 degrees

Angle ADC = 31 degrees

Side AB = 3 units

Now, consider triangle ABD.

Sin (31) = AB/AD

AD = AB/sin 31

AD  = 3/sin 31

AD = 5.82

Therefore, the length of the side AD is 5.82 units.

Answer:

the tree is 8.8 m tall

I can't draw it but it will be two similar acute triangles. The one that represents the man will have a 2m height and a 5m base. The one that represents the tree will have an 8.8m height and a 22 m base.

Step-by-step explanation:

it's a proportional relationship

5/22=2/height

5(height)=2(22)

5(height)=44

divide both sides by 5

5(height)/5=44/5

height=8.8 m

X=-4

Step-by-step explanation:

-2x + 4 = 12

so what you would do is subtract 4 from itself and 12

4 - 4 = 0

12 - 4 = 8

then we have-

-2x = 8

we then divide 2 from 2 and 8

2 divided by 2 = 0

2 divided by 8 = 4

so x = -4
