Answer:
$15.90
Step-by-step explanation:
$1.20 x .25 is the cost of 1/4 pound = $ 0.30
13 lbs × 1.20 = $15.60
15.6 + .3=15.9
Answer:
The largest angle is 90 degrees
Step-by-step explanation:
The three angles of a triangle add to 180
The ratio is 10 : 3: 7
Multiply each by x
10x, 3x 7x
Add them together and set equal to 180
10x+3x+7x = 180
Combine like terms
20x = 180
Divide by 20
20x/20x =180/20
x = 9
The largest angle is 10x
10*9 = 90
The largest angle is 90 degrees
First set both equations equal to y
y = -1/2x + 3
y = 3x - 4
Then set these two equal because they both equal y
-1/2x + 3 = 3x + 4
Combine like terms and solve
7 = 3.5x
x = 2
y also = 2 when you plug it back in
Therefore, (2,2)
Answer:
4/5
Step-by-step explanation:
Answer:
(B)5200
Step-by-step explanation:
Since the value was increased by 30%, the new value in the options is 130% of the initial Value.
Let x be the number of hex nuts in the bin before that delivery.
130% of x = New Value
1.3 of x = New Value
x= New Value ÷ 1.3
Since the number of hex nuts in the bin is a whole number, we test the options to see which satisfies this condition.
- 5100 ÷ 1.3 =3923.08
- 5200 ÷ 1.3=4000
- 5400÷ 1.3=4153.85
- 5500÷ 1.3=4230.77
- 5600÷ 1.3=4307.69
5200 is the only option which satisfies our stated condition.
