Find the diameter of a circle whose circumference is 74cm

Answers

Answer 1
Answer:

≈ 24 cm

Step-by-step explanation:

Hi there !

c = 2πr  } => c = πd => d = c/π

2r = d

replace c ; π

π  =3.14

d = 74cm/3.14

= 23.5668

≈ 24 cm

Good luck !

Find two consecutive odd numbers such that seven times the smaller number is 17 more than six times the larger

Answers

Answer:

29 and 31

Step-by-step explanation:

Let

x = the first odd number

x + 2 = the second odd number

seven times the smaller number is 17 more than six times the larger

7*x = 17 + 6(x + 2)

7x = 17 + 6x + 12

Collect like terms

7x - 6x = 29

x = 29

x + 2 = 29 + 2

= 31

Check:

7*x = 17 + 6(x + 2)

7*29 = 17 + 6(29 + 2)

203 = 17 + 6(31)

203 = 17 + 186

203 = 203

Therefore, the two consecutive odd numbers are 29 and 31

78 Degrees

Step-by-step explanation:

Two supplementary angles:

4x + 2 + 3x + 3 = 180

Combine like terms:

7x + 5 = 180

Simplify

7x = 175

x = 25

(25)3 + 3 = 75 + 3 = 78

Angle DCB is 78 degrees

Answer:

78 Degrees

Step-by-step explanation:

Two supplementary angles:  (GIven)

4x + 2 + 3x + 3 = 180

Combine like terms:

7x + 5 = 180

Simplify

7x = 175

x = 25

(25)3 + 3 = 75 + 3 = 78

So,

Angle DCB is 78 degrees.

Answer:

Step-by-step explanation:

Water is poured into a container at a steady rate. After six minutes, 9.6 gallons of water are in the container. Let g represent the number of gallons of water in the
container after t minutes.
Select the equation that represents the relationship between g and t.
g= 0.6254
gt = 0.625
1.6g =1
g = 1.6t

Answers

Answer:

g = 1.6t

Step-by-step explanation:

Here, we want to select the equation that shows the correct relationship between g and t

We are told that after 6 seconds, we have 9.6 gallons of water

So the amount per second will be 9.6/6 = 1.6 gallons per second

So the relationship between the two will be

g = 1.6t

Where t is the time and g is the gallons

Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below.

Step 1: Expand.

−2[tex]x[/tex] − 18 = 5[tex]x[/tex] − 35

Step 2: Add 2[tex]x[/tex] to both sides.

−18 = 5x − 35 + 2[tex]x[/tex]

Step 3: Simplify 5[tex]x[/tex] − 35 + 2[tex]x[/tex] to 7[tex]x[/tex] − 35.

−18 = 7[tex]x[/tex] − 35

Step 4: Add 35 to both sides.

−18 + 35 = 7[tex]x[/tex]

Step 5: Simplify −18 + 35 to 17.

17 = 7[tex]x[/tex]

Step 6: Divide both sides by 7.

[tex]\frac{17}{7}[/tex] = [tex]x[/tex]

Step 7: Switch sides.

Which error did Mathieu make?

He factored incorrectly.
He did not use the constant as the x-intercept.
He set the factored expressions equal to each other.
He incorrectly solved the equation x + 3 = x + 1.

Answers

Answer:

C

Step-by-step explanation:

Plz mark brainliest

The error is he set the factored expressions equal to each other(option3).

What is X-intercepts?

In a graph, the point where the line or curve crosses the axis is called the intercept. If a point crosses the x-axis it is x-intercepts. If a point crosses y-axis it is y-intercepts.

For finding x-intercepts of the given function,

First we have to factorize the given equation and then find the x values .

In [tex]f(x)=x^{2} +4x+3[/tex]

When we factorize we get , (x+3) and (x+1)

i.e., x+3=0⇒x=-3, x+1=0⇒x=-1.

That is x- intercept is -1 and -3.

Instead of this step Mathieu equated x+3=x+1.

This makes an error.

Hence, the error is he set the factored expressions equal to each other.

If CE bisects ZBCD and if m ZBCE = 3x - 6
and mZECD = 2x + 11, find mZBCD. Is
ZBCD acute, right, or obtuse?

Answers

Answer:

m∠BCD = 90°

∠BCD is a right angle

Step-by-step explanation:

If a ray bisects an angle, that means it divides the angle into two equal parts in measure

Ray CE bisects ∠BCD

→ Means divide it into two angles BCE and ECD which equal in measures

m∠BCE = m∠ECD = [tex]\frac{1}{2}[/tex] m∠BCD

∵ m∠BCE = 3x - 6

∵ m∠ECD = 2x + 11

→ Equate them to find x

3x - 6 = 2x + 11

→ Add 6 to both sides

∵ 3x - 6 + 6 = 2x + 11 + 6

∴ 3x = 2x + 17

→ Subtract 2x from both sides

∵ 3x - 2x = 2x - 2x + 17

x = 17

∵ m∠BCE =  [tex]\frac{1}{2}[/tex] m∠BCD

→ Substitute x in the measure of ∠BCE to find it, then use it to

   find m∠BCD

∵ m∠BCE = 3(17) - 6 = 51 - 6

∴  m∠BCE = 45°

45 = [tex]\frac{1}{2}[/tex] m∠BCD

→ Multiply both sides by 2

∴ 90 = m∠BCD

m∠BCD = 90°

→ The measure of the acute angle is less than 90°, the measure of

   the obtuse angle is greater than 90°, and the measure of the

   right angle is 90°

∠BCD is a right angle

What are sides of a pentagon with different sides ?

If the sides of a pentagon are not equal in measure, it is termed as an irregular pentagon. In this case, the perimeter of the pentagon can be calculated by using the basic formula, Perimeter = sum of its sides.

Given,

side 1 = 2x

side 2 = 10

side 3 = x+2

side 4 = 11

side 5 = 3x-2

Sum of all the sides of the pentagon,

2x+10+(x+2)+11+(3x-2)=63

2x+10+x+2+11+3x-2=63

6x+21=63

6x=63-21

6x=42

x=42/6
