“Calculate the lengths of the 2 unlabeled sides”

Mathematics
1 answer:
Tpy6a [65]3 years ago
8 0

Answer:

NL = 4.33

NM = 5

Step-by-step explanation:

tan 60° = NL/2.5

tan 60° = 1.7321

so:

1.7321 = NL/2.5

NL = (2.5)(1.7321)

NL = 4.33

cos 60° = 2.5/NM

cos 60° = 0.5

so:

0.5 = 2.5.NM

NM = 2.5/0.5

NM = 5

A picnic table was originally priced at 40, but Megan waited to buy the picnic table on sale from 75% off. If she paid 10% sale
Mila [183]

<u>Answer:</u>

she spent total price of 13 on the picnic table

<u>Explanation: </u>

Original price of the table = 40

Since she paid 10% of the sale tax after the sale then the total amount she spend is  

Discount = (discount percentage – sale tax  ) × original price

=  (75% -10%) × 40

= 65 % ×40

=\frac{65}{100} \times 40

=26

Hence after the discount amount  

Original price – discount price

= 40-26 = 13

Hence she spent total price of 13 on the picnic table

A right triangle has a base of 11 yards and a height of 7 yards . If you were to construct a similar but not congruent right tri
Dimas [21]

Answer:

bae of 44 yds and a height of 28 yds

Step-by-step explanation:

11x7 = 88 yd^2 = area of small triangle

616/88 = 16 so the larger triangle area is 16 times larger than the smaller triangle.

The area of a triangle is not proportional to it's dimensions. An increase of 16 times the area only increases the dimensions by 4 times.

larger triangle dimensions are 11 x 4 = 44 and 7 x 4 = 28

Choose the equation that represents a line that passes through points (−1, 2) and (3, 1).
3241004551 [841]

You did not provide us with equations to select.

Find the slope m.

m = (1 - 2)/(3 - (-1))

m = -1/(3 + 1)

m = -1/4

Use the slope and one of the points and plug into the point-slope formula.

y - 1 = (-1/4)(x - 3)

Isolate y.

y - 1 = (-1/4)x + (3/4)

y = (-1/4)x + (3/4) + 1

y = (-1/4)x + (7/4)

Did you follow?
