The sum of 3 consecutive even numbers is 60. What are they?

ASHA 777 [7]

Answer:

18, 20 and 22.

Step-by-step explanation:

Let the lowest number be n, then:

n + n + 2 + n + 4 = 60

3n + 6 = 60

3n = 54

n = 18.

So the other 2 are 20 and 22.

The angle of elevation to the top of a 15-story skyscraper is measured to be 4 degrees from a point on the ground 2,500 feet fro

madreJ [45]

Set up a right triangle
The base will be 2,500 feet and the angle where the hypotenuse meets the base will be 4 degrees
The height is your x value,
tan4=x/2,500
Multiply both sides by 2500
2500tan4=x
x=174.817
The answer is B

Calvin deposits $400 in a savings account that accrues 5% interest compounded monthly. after c years, calvin has $658.80. makayl

pochemuha

Answer:

The approximate difference in time is 2 years.

Step-by-step explanation:

The equation for Calvin's account is

$658.80=400(1+\frac{0.05}{12})^{12c}$

To solve for c, we first divide both sides by 400. This gives us:

$1.647=(1+\frac{0.05}{12})^{12c}$

Using logarithms to solve this, we have

$\log_{1+\frac{0.05}{12}}1.647=12c\\\\119.9986131=12c$

Dividing both sides by 12, we get c = 9.9998 or around 10 years.

The equation for Makayla's account is

$613.04=300(1+\frac{0.06}{4})^{4m}$

Dividing both sides by 300, we get

$2.043466667=(1+\frac{0.06}{4})^{4m}$

Using logarithms to solve this, we have

$\log_{1+\frac{0.06}{4}}2.043466667=4m\\\\4m=47.9961799$

Dividing both sides by 4, we get

m = 11.9999 or about 12.

This means Makayla had her money in the account 12-10 = 2 years longer than Calvin.

What are the steps for using a compass and straightedge to construct the bisector of ∠G? Two rays share a common endpoint labele

Dahasolnce [82]

Answer:

Ordered steps to bisect angle G is given below.

Step-by-step explanation:

1. Place the point of the compass on point G and draw an arc that intersects the sides of ∠G.

2.Label the points of intersection as points H and J.

3. Place the point of the compass on point H and draw an arc in the interior of the angle.

4. Without changing the opening of the compass, place the point of the compass on point J and draw another arc in the interior of the angle.

5.Label the intersection of the arcs in the interior of the angle as point K.

6. Use the straightedge to draw GK.
