Answer:

Step-by-step explanation:

7x + 6 + 15x - 2 = 180 {Linear Pair}

7x + 15x + 6 - 2 = 180 {Combine like terms}

22x + 4 = 180

22x = 180 - 4

22x = 176

x = 176/22

x = 8

7x + 6 = 7*8 + 6 = 56 + 6 = 62

5y - 3 = 62 {Vertically opposite angles are equal}

5y = 62+ 3

5y = 65

y = 65/5

y = 13

4) 4x - 30 + x + 90 = 180 {supplementary angles}

5x + 60 = 180

5x = 180 - 60

5x = 120

x = 24

x = 24

Smallest angle = 4x - 30 = 4*24 - 30 = 96 -30 =66

The accountant charged $35 for the first hour of work and $23 for each hour after that.He earned a total of$127 how many hours d

dexar [7]

Answer:

He worked a total of 5 hours.

Step-by-step explanation:

The first hour the man makes $35 dollars for the first hour then for the other hours he earns $23 dollars, right? So we start off with 35.

35 = one hour.

35 + 23 = 2 hours . = 58.

35 + 23 + 23 = 3 hours. = 81.

35 + 23 + 23 + 23 = 4 hours. = 104.

35 + 23 + 23 + 23 + 23 = 5 hours. = 127.

We were looking for if the man earned $127 dollars how many hours would be be working.

He'd be working 5 hours.

Hope this helps (:

Does anybody know the answer to these questions?

san4es73 [151]

Answer:

1. 625,000 J

2. 100 J

4. 5 kg

5. √5 ≈ 2.236 m/s

Step-by-step explanation:

You should be aware that the SI derived units of Joules are equivalent to kg·m²/s².

To reduce confusion between m for mass and m for meters, we'll use an italic m for mass.

In each case, the "find" variable is what's left after we put the numbers into the formula. It is what the question is asking for. The "given" values are the ones in the problem statement and are the values we put into the formula. The formula is the same in every case.

1. KE = (1/2)mv² = (1/2)(2000 kg)(25 m/s)² = 625,000 kg·m²/s² = 625,000 J

2. KE = (1/2)mv² = (1/2)(0.5 kg)(20 m/s)² = 100 kg·m²/s² = 100 J

4. KE = (1/2)mv²

250 J = (1/2)m(10 m/s)² = 50 m²/s²

(250 kg·m²/s²)/(50 m²/s²) = m = 5 kg

5. KE = (1/2)mv²

2000 kg·m²/s² = (1/2)(800 kg)v²

(2000 kg·m²/s²)/(400 kg) = v² = 5 m²/s²

v = √5 m/s ≈ 2.236 m/s

What would be the function for this?

coldgirl [10]

Answer:

f(x) = 2x + 4

Step-by-step explanation:

This is an arithmetic sequence

y = a1 + (x - 1)d where a1 = first term and d = common difference so it is

y = 6 + (x - 1)*2

y = 2x + 4 answer

Sphere and a cylinder have the same radius and height. The volume of the cylinder is 64 meters cubed.

Mrrafil [7]

Answer:

C. 128/3 meters cubed

Step-by-step explanation:

The volume of a cylinder is denoted by: $V=\pi r^2h$ , where r is the radius and h is the height. We know it's equal to 64, so we can set that equal to V:

$V=\pi r^2h$

$64=\pi r^2h$

We know that the sphere and cylinder have the same height and radius. However, the "height" of a sphere is actually the same as its diameter, which is twice its radius. Then, we can replace h in the above equation with 2r:

$64=\pi r^2h$

$64=\pi r^2*2r=2\pi r^3$

$\pi r^3=64/2=32$

Now, the volume of a sphere is denoted by: $V=\frac{4}{3} \pi r^3$ , where r is the radius. From above, we know that $\pi r^3=32$ , so we can plug this into the equation:

$V=\frac{4}{3} \pi r^3$

$V=\frac{4}{3} *32=128/3$

Thus, the answer is C.

Solve each two-step inequality and graph the solution set on a number line -17 < 3-5x

lawyer [7]

Answer:

$x < 4$

Step-by-step explanation:

Given the following question:

$-17 < 3-5x$

In order to find the answer, we will solve the inequality as if it is a regular two-step equation and then we will plot the answer on the number line.

$-17 < 3-5x$
$-17 < 3-5x=3-5x > -17$
$3-5x > -17$
$3-3=0$
$-17--3=-20$
$5x=-20$
$\frac{5x}{5}=x$
$20\div5=-4$
$x < 4$

When plotting inequalities on the number line keep a few things in mind:

. 4 is greater than x, so the line will go towards the opposite direction of four
. < is a greater sign, it's not a greater or equal to sign (≤) which means it will be an open dot.

Hope this helps.
