Michelle has a round lamp to which she wants to add beads. The diameter is 12.2. How many inches of the beads will she need to go around the lamp
Answers
Answer: 38.31 inches
Step-by-step explanation:
We can think on the round lamp as a circle, then the inches of beads that she will need to go around the lamp is equal to the perimeter of the lamp.
The perimeter of a circle of diameter D, is:
Perimeter = pi*D
where pi = 3.14
In this case, we know that the diameter is 12.2 inches.
Replacing that in the above equation we get that the diameter of the lamp is:
Perimeter = 3.14*12.2 in = 38.31 in
Then Michelle needs 38.31 inches of the beads to go around the lamp.
Delia went to the market to buy 4 pounds of sliced fruit in a container. She paid with a $20 bill and a $5 bill and received $3.67 as change. She paid $1.29 in taxes for the fruit. What was the cost for one pound of sliced fruit before taxes?
Answers
Answer:
$4.57. Hope this helps :)
Step-by-step explanation:
20+5=25
then you do
25-3.67= $21.33
you then divide that by the number of pounds she bought.
21.33/4= 5.3325
round that to the hundreths place and you get $5.33
so she paid $5.33 for a pound
Answer:
$4.74 per pound
Step-by-step explanation:
((20 + 5) – 3.67) / 4.5 = (25 – 3.67) / 4.5 =
(21.33) / 4.5 = 4.74

The diameter of the wheel of a unicycle is 0.7m. Elaine tries to ride the unicycle and manages to go in a straight line for 32 full revolutions before falling off. How far did Elaine manage to cycle in metres? Give your answer rounded to 1 DP.
Answers
Answer:
70.4metres
Step-by-step explanation:
Wheel Diameter = 0.7m
Wheel Radius; 0.7m / 2 = 0.35m
For one rotation of the wheel, the distance travelled = circumference of the wheel.
Circumference = 2 x pi x radius
= 2 × π × r
= 2 × π × 0.35
= 2.1991148575 m
Elaine tries to ride the unicycle and manages to go in a straight line for 32 full revolutions
Distance travelled with 32 full revolutions of the wheel = 32 x 2.1991148575 m =
Distance in meters = 70.37167544m
Approximately = 70.4m
Therefore, Elaine managed to cycle 70.4metres

Solve algebraically the simultaneous equations
y = 2x2 – 3x - 10
2x - y = -2
Answers
Answer:
(-3/2, -1) and (4, 10)
Step-by-step explanation:
Given the simultaneous equations
y = 2x^2 – 3x - 10 ... 1
2x - y = -2 .... 2
From equation2;
-y = -2-2x
y = 2x+2 ..... 3
Substitute 3 into 1
Recall y = 2x^2 – 3x - 10
2x+2 = 2x^2 – 3x - 10
Collect like terms
2x^2 – 3x - 10 - 2x -2 = 0
2x^2 – 5x - 12 = 0
2x^2 – 8x+3x - 12 = 0
2x(x-4)+3(x-4) = 0
(2x+3)(x-4) = 0
2x+3 = 0 and x-4 = 0
2x = -3 and x = 4
x = -3/2 and x = 4
Recall that
y = 2x+2
when x = -3/2
y = 2(-3/2) + 2
y = -3+2
y = -1
when x = 4
y = 2(4)+2
y = 8+2
y = 10
Hence the solutions are (-3/2, -1) and (4, 10)

Simplifying
x + 7x = 56 + 8
Combine like terms: x + 7x = 8x
8x = 56 + 8
Combine like terms: 56 + 8 = 64
8x = 64
Solving
8x = 64
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '8'.
x = 8
