Answers

Answer 1

Answer:

7.6

14.8

23.2

Step-by-step explanation:

a = 1.6, a = 4, a = 6.8

3a + 2.8 when a = 1.6

= 3(1.6) + 2.8

= 4.8 + 2.8

= 7.6

3a + 2.8 when a = 4

3(4) + 2.8

= 12 + 2.8

= 14.8

3a + 2.8 when a = 6.8

= 3(6.8) + 2.8

= 20.4 + 2.8

= 23.2

LMNP is inscribed in circle R. If the measure of angle P = 57°, and angle L = angle N, what are the measures of angle M, angle L, and angle N? Please help!!!!

Answers

Answer:

m∠M = 123° ; m∠L = m∠N = 90°

Step-by-step explanation:

A quadrangle LMNP is inscribed in circle which means:

m∠L + m∠N = m∠P + m∠M = 180°

m∠P + m∠M = 180°

57° + m∠M = 180°

m∠M = 123°

m∠L + m∠N = 180° and m∠L + m∠N

m∠L + m∠L = 180°

2×m∠L = 180°

m∠L = 90°

m∠N = m∠L = 90°

Step-by-step explanation:

dont trust me for edulastic questionsss but I think thats correct

Answer:

9424.78 in^3

Step-by-step explanation:

Use formula V= pi(r^2)(H). V is volume, r is radius, and h is height. You are given the radius(10) and the height(30). Plug it into the formula to get V=pi(10^2)(30), which will solve for 9424.78. (Use 3.14 instead of pi in the formula, because the question says to do so)

(08.01 LC)
Two lines, A and B, are represented by the equations given below:
Line A: x + y = 2
Line B: 2x + y = 4
Which statement is true about the solution to the set of equations? (5 points)
1) There are infinitely many solutions.
2) There are two solutions.
3) There is one solution.
4) There is no solution.

Answers

Answer:

(2, 0)

There is one solution

Step-by-step explanation:

Given the set of equations

x+y = 2

2x+y = 4

Substract both equations

x - 2x = 2 - 4

-x = -2

Multiply thrugh by -1

-1(-x) = -1(-2)

x = 2

Substitute x = 2 into equation1 ;

From 1, x+y = 2

2 + y = 2

y = 2-2

y = 0

hence the solution to the system of equation is (2, 0). Hence there is only one solution

Answer:

There is one solution.

The deli scale weighs meat and cheese in hundredths of a pound. Sam put 4 10 pound of pepperoni on the deli scale. What weight does the deli scale show? The scale shows pound.

Answers

Answer:

[tex]0.40\ \text{Pounds}[/tex]

Step-by-step explanation:

The mass of pepperoni placed on the scale is

[tex]\dfrac{4}{10}\ \text{pounds}[/tex]

[tex]=0.4\ \text{Pounds}[/tex]

The hundredths place means 2 digits after the decimal point.

Trailing zeros after the decimal point do not change the value of the number.

So, here the scales will show [tex]0.40\ \text{Pounds}[/tex].
