Mathematics

STatiana [176]3 years ago
3 0

Answer:

Spine length = 48 cm

Step-by-step explanation:

So the little marks at the top of the kite closely resemble the "right angle" symbol, but it's a trick

The top angle can be found using the law of cosines

78² = 62² + 62² - 2(62)(62)cosθ

78² = 2(62²) - 2(62²)cosθ

cosθ = (78² - 2(62²)) / -2(62²)

cosθ = 0.2086...

θ = 77.9575...°

Spine = 62cos(77.9575 / 2)

Spine =  48.1975...

Help me solve this problem please

Her mother did not gave her enough money.
each pound of bananas costs 80 cents. 5 pounds of that is $0.8 x 5 = $4.00
each pound of apples costs $1.40. 5 pounds of that is $1.40 x 5 = $7.00
$4.00 + $7.00 = $11.00
Therefore, she needs 11 dollars to buy 5 pounds of each bananas and apples. She needs to ask her mother for 1 more dollar.

Toni can carry up to 18 lb in her backpack. Her lunch weighs 1 lb, her gym clothes weigh 2 lb, and her books (b) weigh 3 lb each
Sergeu [11.5K]
Toni can carry up to 5 books

1+2+3b=18
combine 1 and 2
3+3b=18
subtract 3 from both sides
3b=15
divide 3 from both sides
b=5

REY [17]

9514 1404 393

Answer:

  (a)  an = -4·2^(n-1)

Step-by-step explanation:

The form for the general term is ...

  an = a1·r^(n-1) . . . . . a1 is the first term; r is the common ratio

For a1=-4 and r=-8/-4 = 2, the rule will be ...

  an = -4·2^(n-1)

What is the value of the expression below when y=6y=6? y^2 -5y-4 y 2 −5y−4
Elodia [21]

Answer:

2

Step-by-step explanation:

Given expression:

y^2 - 5y - 4

y = 6

Substitute y = 6 into the expression

y^2 - 5y - 4

6^2 - 5(6) - 4

(6*6) - (5*6) - 4

36 - 30 - 4

36 - 34

2

The value of the expression y^2 - 5y - 4 is 2 when y = 6
