Answer:
7/22
Step-by-step explanation:
Area = 400/200 × 400/200 ×1/4 × 7/22 = 7/22
Step-by-step explanation:
Total distance covered in 200 rotation = 440 m
Distance covered in 1 rotation
= 440 / 200
= 2.2 m
Distance covered in 1 rotation = Circumference of circle so
circumference = 2πr
2.2 = 2 * 22/7 * r
2.2 = 6.28 r
r = 2.2 / 6.28
r = 0.35 m
Now Area of the wheel
= πr²
= 22 /7 * 0.35 * 0.35
= 0.385 m²

how do you solve 2x+4y=7 and -2x +3y=14
Answer:
y=3 x= -5/2
Step-by-step explanation:
simultaneous equations
2x + 4y = 7 ------ eq 1
-2x + 3y = 14 --------eq2
(different signs add)
(eq 2 + eq 1)
-2x +(-2x) = 0
4y+3y = 7y
7+14 = 21
7y= 21
(divide both sides by 7)
y= 21/7= 3
2x + 4(3) = 7
2x+ 12=7
2x = 7-12
2x = -5
x= -5/2

In rectangle QRST, QS = 5x - 31 and RT = 2x + 11.
Find the lengths of the diagonals of QRST.
A.4
B.6
C.14
D.16
Answer:
C
Step-by-step explanation:
The diagonals of a rectangle are congruent, then
5x - 31 = 2x + 11 ( subtract 2x from both sides )
3x - 31 = 11 ( add 31 to both sides )
3x = 42 ( divide both sides by 3 )
x = 14
Then
RT = 2x + 11 = 2(14) + 11 = 28 + 11 = 39
The diagonals are each 39 units

Step-by-step explanation:
Which equation best represents c, the total amount Mr. Thomas should be charged
for driving m miles?
Answer:
c = 0.15m + 45
Step-by-step explanation:
Generally, we have the equation of a straight line as;
y = mx + b
where m is the slope and b is the y-intercept
To get the value of m, we can use the slope equation
m = (y2-y1)/(x2-x1)
Let us select two points to use from the table
we have;
(40,51) and (20,48)
So substituting these values;
m = (48-51)/(20-40) = 0.15
So we have the partially completed equation as;
y = 0.15x + b
To get the value of b, we use any of the points
Using the last, we have
51 = 0.15(40) + b
b = 45
So we have the complete equation as;
y = 0.15x + 45
using the terms in the question, we have;
c = 0.15m + 45

Answer:
g(h(x)) = 9x² + 12x - 3

g(h(x)) = (3x² + 2)² - 7
= 9x² + 6x + 6x + 4 - 7
= 9x² + 12x - 3
h(g(x)) = 3(x² - 7) + 2
= 3x² - 21 + 2

1. A construction worker was preparing wood for a project.
He had 1/4 of a meter of wood that he needed to cut
into equal size pieces. If he cut the wood into 6 pieces,
how long will each piece be?
Answer:
4.17 cm
Step-by-step explanation:
I took 1m=100cm
Then divided the cm by 4 to get the 1/4 of a meter which is 25
25/6 is 4.16repeating so I rounded it up to 4.17.
If your teacher wants it in a fraction I would state it as 25/6 cm
7(m+-13)=-42
(Solve for m)
Please help
Answer:
m=7
Step-by-step explanation:
Replace all occurrences of + − with a single -. A plus sign followed by a minus sign has the same mathematical meaning as a single minus sign because 1⋅ − 1 = − 1
7(m-13)=-42
Divide each term by 7 and simplify.
m-13=-6
Move all terms not containing m to the right side of the equation.
m=7
