Answer:

L = 260 cm^2

Step-by-step explanation:

height h = 12 cm

slant height s = 13 cm

side length a = 10 cm

lateral edge length e = 13.928388277184 cm

1/2 side length r = 5 cm

volume V = 400 cm^3

lateral surface area L = 260 cm^2

base surface area B = 100 cm^2

total surface area A = 360 cm^2

Genda: h = height

s = slant height

a = side length

e = lateral edge length

r = a/2

V = volume

L = lateral surface area

B = base surface area

A = total surface area

By rounding each number to 1sf estimate the answers to 8.2*6.7/ 0.46
LiRa [457]

Answer:

Please check the explanation.

Step-by-step explanation:

Given the function

8.2\times \frac{6.7}{0.46}

\mathrm{Multiply\:fractions}:\quad \:a\times \frac{b}{c}=\frac{a\:\times \:b}{c}

=\frac{6.7\times \:8.2}{0.46}

\mathrm{Multiply\:the\:numbers:}\:6.7\times \:8.2=54.94

=\frac{54.94}{0.46}

=100        (Round to 1 significant number)

If the purchase price for a house is $309,900, what is the monthly payment if you put 20% down for a 30 year loan with a fixed r
lorasvet [3.4K]

Answer:

The correct answer is A. $729.98.

Step-by-step explanation:

Given that the purchase price for a house is $ 309,900, to determine what is the monthly payment if you put 20% down for a 30 year loan with a fixed rate of 6%, the following calculation must be performed:

100 - 20 = 80

(309,900 x 0.80) x 1.06 / (30x12) = X

247,920 x 1.06 / 360 = X

262,795.2 / 360 = X

729.98 = X

Therefore, the monthly payments will be $ 729.98.

A card is drawn from a​ well-shuffled deck of 52 cards. Find the probability of drawing a diamond or a spade.
AveGali [126]

Answer:

2/13

Step-by-step explanation:

For a deck of card

Total cards = 52

Total spade = 4

Total diamond = 4

pr(drawing a spade) = number of spade/total cards

pr(drawing a spade) = 4/52 = 1/13

pr(drawing a diamond)  = 4/52 = 1/13

Pr(diamond or a spade) = 1/13 + 1/13 = 2/13

An apple sells for 25 cents and a peach sells for 15 cents. A total of 10 fruits were sold for a total of $2.10. How many apples
hammer [34]

Answer:

6 apples

Step-by-step explanation:

A = 0.25

P = 0.15

----------------

A + P = 10

0.25A+0.15P=2.10

----------------

I did this: 0.25*10 = 2.50

2.50-2.10=.40

0.25-0.15=0.10

0.40/0.10 = 4 so 4 peaches

10 fruits - 4 peaches = 6 apples
