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.
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
Given the following 30-60-90 triangle , find the value of x and y Round to the nearest tenth x = 5.2 X = 6 Y = 6 Y = 5.2
Step-by-step explanation:
tan30° = Opposite/Adjacent = 3/x.
=> 3/x = √3/3, x = 3√3 = 5.2.
sin30° = Opposite/Hypotenuse = 3/y.
=> 3/y = 1/2, y = 6.
The correct answer is the 1st and 3rd options.
Answer:
[tex] \huge \boxed{ \boxed{ \sf \: x = 5.2 \atop\sf y = 6}}[/tex]

determinar la magnitud del peso de una persona cuya masa es de 90kg
Creo que la respuesta es 880.2N. Para calcular el peso se utiliza la siguiente fórmula (m×g) (masa multiplicada por la gravedad). El valor de aceleración de la gravedad en la tierra es de 9.78m/s². Por lo que la operación final sería 90×9.78= 880.2Newtons
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?
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
_______________________________
I've seen this same problem before, it should be 4.5 pounds.
Solve algebraically the simultaneous equations
y = 2x2 – 3x - 10
2x - y = -2
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)

Use both the addition and multiplication properties of inequality to solve the inequality. Graph the solutions on a number line. 2(5y-7) > -24 Solve the inequality for y. Select the correct choice below and fill in the answer box to complete your choice.
Please solve ASAP- Reward is 25 points
Answer:
y> -1
Step-by-step explanation:
2(5y-7) > -24
Then use the Distributive Property which then eqauls to this: 10y - 14 > -24
add 14 to both sides: 10y > -10
divide by 10: y> -1
Find the value of x.
56°
57°
85
2x
4x
Answer:
56
Step-by-step explanation:
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
Simplifying
x = 8

£6000 is divided between Adam, Ben and
Chris in the ratio 1:3:4. How much does Ben receive?
Answer:
Chris gets £3000
Step-by-step explanation:
A : B : C
1 : 3 : 4 = 8 (add all the parts together)
£6000 ÷ 8 = 750
so the multiplier is x 750
1 : 3 : 4
↩ x 750
750 : 2250 : 3000

Area as a Product:
I need the are as a sum Nd a product
Given:
The area model.
To find:
The area as a sum and area as a product.
Solution:
The four terms of the area model are [tex]2x^2,10x, 3x, 15[/tex].
The area as a sum is the sum of all the terms of given area model.
Area as a sum = [tex]2x^2+10x+3x+15[/tex]
= [tex]2x^2+13x+15[/tex]
The area as a product is the factor form of sum of all the terms of given area model.
Area as a product = [tex]2x^2+10x+3x+15[/tex]
= [tex]2x(x+5)+3(x+5)[/tex]
= [tex](x+5)(2x+3)[/tex]
Therefore, the area as a sum is [tex]2x^2+13x+15[/tex] and the area as a product is [tex](x+5)(2x+3)[/tex].
Explain, with details, why |−10|>|3|. Plz help tell why 10 is bigger than three 15 point
Answer:
|-10| is bigger than |3| because when taking the absolute value (the vertical line) of a number, you are counting how far away from 0 it is meaning that both 10 and -10 are 10 spaces away from 0. The negative doesn't matter.

Hey we go to the same schoola and have the same class so thats cool. Also i think it might be the reverse of what we did on question five where we divide the measure of the arc by two instead of multiplying the angle by two to get the arc. If this is true then our answer will be 49*
