What is 58 times 8 using cumulative property

1 answer:

7 0

58 x 8 would be equal to 464. If you do 8 x 8 it'd be 64. And 8 x 50'd be 400. If you add up 64 + 400, you will get 464.

Geometry proofs help me please :)

REY [17]

Answer:

2) Right angles always equal 90°

3) m∠F = 90° and m∠G = 90° which means they have the same angle measure.

4) Removing the m and replacing with the congruent symbol.

I'm not too sure how this goes but it should be something like that.

Find the value of x, y, and z in the figure below: ہ 2y IN 2x 90° t

natima [27]

Answer:

x=30°

y=15°

z=150°

Step-by-step explanation:

2x+90+x=180°

2x=180°-90°

x=90/3

x=30

2y=x

y= 30/2

y=15°

2y°+z°=180°

2(15°)+z°=180°

z=180°-30°

z=150°

Hope it helps! :)

An investor invests $2,500 into a mutual fund and earns 5.75% on the principle for each of three years. How much interest has ac

HACTEHA [7]

Answer:

Interest in 3 years = $456.52

Step-by-step explanation:

As we know the the formula of compound interest

Total amount = $A(1+\frac{r}{n})^{nt}$

Here n = number of times amount is compounded

r = rate of interest

t = period

Here A = $2500

r = 0.0575

n = 1 (compounded annually)

t = 3 years

Therefore amount after 3 years

$P=2500(1+\frac{.0575}{1})^{3}$

P =2500(1.0575)³

= 2500×1.18

= $2956.52

We have to calculate the interest then

Interest = $2956.52-$2500 = $456.52

So after 3 years interest gained = $456.52
