<span>To solve these GCF and LCM problems, factor the numbers you're working with into primes: 
3780 = 2*2*3*3*3*5*7
180 = 2*2*3*3*5 
</span><span>We know that the LCM of the two numbers, call them A and B, = 3780 and that A = 180. The greatest common factor of 180 and B = 18 so B has factors 2*3*3 in common with 180 but no other factors in common with 180. So, B has no more 2's and no 5's
</span><span>Now, LCM(180,B) = 3780. So, A or B must have each of the factors of 3780. B needs another factor of 3 and a factor of 7 since LCM(A,B) needs for either A or B to have a factor of 2*2, which A has, and a factor of 3*3*3, which B will have with another factor of 3, and a factor of 7, which B will have. 
So, B = 2*3*3*3*7 = 378.</span>

Judith has \$70 in a savings account that earns 5% interest , compounded annually .
Firlakuza [10]

Answer:

$81.03

Step-by-step explanation:

Given

n = 1 --- annually

t =3 --- time

r = 5\% --- rate

PV = \$70 ---- Present value

Required

The future value

This is calculated as:

FV = PV * (1 + \frac{r}{n})^{nt}

This gives:

FV = 70 * (1 + \frac{5\%}{1})^{1*3}

FV = 70 * (1 + 5\%)^3

FV = 70 * (1.05)^3

FV = 70 * 1.157625

FV = 81.03375

<em>The future value to the nearest cent is: $81.03</em>

A hiker is climbing down a valley. He stops for a water break 4 times. Between each break, he descends 15 meters. How many meter
Murljashka [212]

The word in the problem that indicates that a negative sign should be used is "descend"

<h3></h3><h3>How many meters did he descend?</h3>

We know that he stops for water breaks four times, and between each water break, he descends 15 meters.

The written equation is:

4*(-15)m = -60m

Why the negative sign is used?

The negative sign is used because the hiker is descending, so its height is decreasing. The word in the problem that indicates that a negative sign should be used is "descend"

Michelle drew a scale drawing of a swimming pool she used the scale 14 millimeters 5 meters in the drawing the pool is 42 millim
Lera25 [3.4K]

EXPLANATION

Let's see the facts:

The scale is---> 14 milimeters ----> 5 meters

Width = 42 milimeters

Applying the unitary method, the actual width of the pool is:

Actual_{}width=42\text{ mm}\cdot\frac{5m}{14\text{ mm}}=15m

The width of the pool is 15m
