Answers

Answer:

? = 109 degrees

Step-by-step explanation:

45 + 75 + _ = 180  ( look for vertical angles)

45 + 75 + 60 = 180

60 +79 + _ = 180 (look for a straight line that forms 180 degrees)

60 + 79 + 41 = 180

68 + 41 + _ = 180 (look for a triangle that adds up to 180)

68 + 41 + 71 =180

180 - 71 = 109 (look for a linear pair)

Answers

Answer:

[tex]k[/tex]+([tex]x[/tex]×[tex]x[/tex])

Step-by-step explanation:

k is the number of pencils jerry has, and x is the number of pencils darcy and leonard gave him EACH. So you need to multiply 'x' x2 to get the total ammount of pencils they gave him, then add 'k' to know how much in total he has now.

What is the best estimate of the area of the figure in square inches?

Answers

Answer = 86.135 squared.

To find the area of this figure the best action would to divide it into three different sections, finding the area of each and then adding them all together.

First, find the area of the square in the center, which would be 60in.

Second, find the area of the half circle. You would use the formula for area of a circle. You would divide this answer by 2 since this is only half of a circle. You would get 14.135in.

Last, you would find the area of the triangle. You would multiply both sides and then divide by 2, since it’s a triangle and not a square. Area for this is 12in.

And then you would add all these together.

Answer:

86.1372 -------> 86.1 (Nearest Tenths)

86.1372 -------> 86.14 (Nearest Hundreths)

86.1372 --------> 86.137 (Nearest Thousandths)

Step-by-step explanation:

Semicircle: 3.14*[tex]3^{2}[/tex]/2 = 14.1372

Triangle: 4*6 = 24/2 = 12

Rectangle: 10*6 = 60

14.1372 + 12 + 60 = 86.1372

86.1372 -------> 86.1 (Nearest Tenths)

86.1372 -------> 86.14 (Nearest Hundreths)

86.1372 --------> 86.137 (Nearest Thousandths)

Which angle is supplementary to angle # 3? (Brainliest + Bonus points for the best correct and explanatory answer)

Answers

Angle #2 is supplemental to angle #3. Supplemental angles add up to 180 degrees, so when you look at angle #3, the only other adjacent angle to #3 that yields a sum of 180 degrees is angle #2.

You can always tell angles are supplemental when they create a straight line, which is 180 degrees.

35 is 29% of what number

Answers

Answer:

10.15 is 29% of 35.

Step-by-step explanation:

The scale of a map is 1:4 000 000. Hint: 1:4 000 000 means that 1cm on the map = 4 000 000 on the ground. The distance between Leeds and London on this map is 8.125cm. Calculate the actual distance between Leeds and London. Give your answer in kilometres.

Answers

Answer:

325 km

Step-by-step explanation:

Given the scale :

1 : 4 ,000, 000

1cm measure in map = 4000000 on the ground

From the map :

Distance between Leeds and London = 8.125 cm

The actual distance on ground can be calculated thus :

1cm = 4,000,000

8.125cm = x

Cross multiply

x = 32500000 cm

Converting to kilometers :

1 km = 100,000 cm

x = 32500000

Cross multiply

100,000x = 32500000

x = 32500000 / 100000

x = 325

Hence, actual distance between Leeds and London is 325 km

A. -4

B. 1/4

C. -1/4

D. 4​

Answers

Answer:

-4 is the slope

Step-by-step explanation:

Because the line is going downwards that makes it a negative and if you count the boxes rise over run. You look for the point where the line meets a box perfectly and then you count the boxes down which is 4 and across which is one which makes it -4/1. So the slope is -4.

Answer: Lower-right corner  [tex]3^7 \times \frac{1}{3^4}[/tex]

Explanation:

We use the rule that

[tex]a^{-b} = \frac{1}{a^b}[/tex]

The negative exponent tells us to apply the reciprocal if we want the exponent to be positive.

In this case, a = 3 and b = 4

So,

[tex]a^{-b} = \frac{1}{a^b}\\\\3^{-4} = \frac{1}{3^4}[/tex]

which is why overall,

[tex]3^7\times 3^{-4} = 3^7 \times \frac{1}{3^4}[/tex]

Given that y varies directly with x, use the specified values to write a direct 1 point
variation equation that relates x and y. x = 24 y=-6*

Answers

Answer:

y = - [tex]\frac{1}{4}[/tex] x

Step-by-step explanation:

Given that y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition x = 24, y = - 6

- 6 = 24k ( divide both sides by 24 )

[tex]\frac{-6}{24}[/tex] = k , that is

k = - [tex]\frac{1}{4}[/tex]

y = - [tex]\frac{1}{4}[/tex] x ← equation of variation

What are the x and y intercepts for this equation? 2x - 3y = 6

Then, write each intercept in coordinate form. Show ALL your work

Slope intercept form is y=2/3x-2

Answers

Answer:

x = 20°

Step-by-step explanation:

An equilateral triangle has three equal angles of 60° each.

Since ∆BCD is an equilateral triangle, it follows that:

<CBD = <BCD = <CDB = 60°

m<ACD = 40° + <BCD

m<ACD = 40° + 60° (substitution)

m<ACD = 100°

x + m<ACD + CDB = 180° (sum of triangle)

x + 100° + 60° = 180° (substitution)

x + 160 = 180

Subtract 160 from each side

x = 180 - 160

x = 20°
