Answer:
3 days
Step-by-step explanation:
Some of Hannah‘s plants need water every 1 day.
Some need water every third(3) day.
If she waters them all today, we are to determine when next she will waters them all again.
To do this, we find the lowest common multiple of 1 and 3.
L.C.M of 1 and 3=3
Therefore, in 3 days time, she will water them all again.

Given that events A and B are independent with P(A) = 0.65 and
P(A n B) = 0.52, determine the value of P(B), rounding to the nearest
thousandth, if necessary.
Answer:
0.80
Step-by-step explanation:
For independent events:
P(A and B) = P(A) P(B)
0.52 = 0.65 P(B)
P(B) = 0.80

56.52 km is the circumference of the circle.
Determining the circumference of a circle.The given figure is a circle with diameter 18km. The formula for calculating the circumference is expressed as:
C = 2πr
radius = diameter/2
radius = 18km/2
radius = 9km
Substitute to have:
C = 2(3.14)(9)
C = 56.52 km

PLEASE HELP ME 40 POINTS
Answer:
see below
Step-by-step explanation:
A: radius of 12 ft
Changing to meter
12 ft * .305 m/ ft =3.66 meter
The radius is 3.66 meters
The diameter is twice the radius = 2*3.66 =7.32 meters
The circumference is
C = pi*d = 3.14 * 7.32 =22.9848 = 22.98 meters
B diameter is 7.5 meters
Pool B has a bigger diameter
C = pi * d = 3.14 * 7.5m = 23.55 meters
The difference is .57 meters
Answer:
7.32
B
Larger/greater
0.57
Step-by-step explanation:
Diameter = 2 × radius
= 2 × 12 = 24 feet
24 × 0.305 = 7.32 meters
7.5 > 7.32
So the diameter of pool B is greater
Difference in circumferences:
(3.14 × 7.5) - (3.14 × 7.32)
23.55 - 22.98
0.57 meters

Answer:
x = 65
Step-by-step explanation:
Complete question is:
Which is the correct solution?
x = 1.8
x = 2.6
x = 45
x = 65
SOLUTION:
The given equation is : [tex]\frac{x}{5}-2=11[/tex]
Substituting all the values of 'x' one by one
-> For x = 1.8 : [tex]\frac{1.8}{5}-2=11[/tex]
-1.64≠11
-> For x = 2.6 : [tex]\frac{2.6}{5}-2=11[/tex]
-1.48≠11
-> For x = 45 : [tex]\frac{45}{5}-2=11[/tex]

Substitute 7 for a.
Simplify the equation after substituting the value for a.
Verify that a = 7 is correct when the result is a true statement.
Step-by-step explanation:
Here, the given equation is,,
And, after solving it the result is,
a = 7
We can check whether a result is the solution of an equation by substituting the result in the given equation.
If we get a true statement, then the result is the solution of the equation.
Thus, for verifying the solution, steps are as follow,
Step 1 : Substitute 7 ,
-9(7-5) = -18
Step 2 : Simplify the equation after substituting the value of a
-9(2) = -18
Step 3 : Verify that a = 7 is correct when the result is a true statement.
-18 = -18

4(2x-1)= 3x-19
Answer:
x = -3
Step-by-step explanation:
In an equation our aim is to find the value of what we are looking for as well as keeping the equation balanced. For example if we took away 4 only from one side then the equation would change so it's an important rule to keep in mind when solving equations, that you need to keep both sides of the equation the same.
4 ( 2x - 1 ) = 3x - 19
→ Expand the brackets
8x - 4 = 3x - 19
→ Minus 3x from both sides to isolate -19 and bring all the x coefficients to one side
5x - 4 = -19
→ Add -4 to both sides to isolate 5x
5x = -15
→ Divide both sides by 5 to isolate x and therefore find the value of x
x = -3
→ We can substitute x = -3 back into 4 ( 2x - 1 ) = 3x - 19 to see if we have the correct solution, if we end with the same number on both sides then x = -3 is correct.
4 ( 2x - 1 ) = 3x - 19
8x - 4 = 3x - 19
( 8 × -3 ) - 4 = ( 3 × -3 ) - 19
-24 - 4 = - 9 - 19
-28 = -28
So x = -3 is correct
A cylinder has a radius of 3 inches and a height of 6imches .What is the volume?
Answer:
-The volume of a cylinder can be either:
In terms of pi: [tex]54\pi[/tex]
or
Using 3.14 for pi: [tex]169.646[/tex] [tex]in^3[/tex]
Step-by-step explanation:
Use the formula for the volume of a cylinder and use the given radius and height for the formula:
[tex]V = \pi r^2 h[/tex]
[tex]V = \pi 3^26[/tex]
Then, solve the formula:
[tex]V = \pi \times 3^2 \times 6[/tex]
[tex]V = \pi \times 9 \times 6[/tex]
[tex]V = \pi \times 54[/tex]
[tex]V = 54\pi \approx 169.646[/tex]
-So, the answers would be:
In terms of pi: [tex]54\pi[/tex]
or
Using 3.14 for pi: [tex]169.646[/tex] [tex]in^3[/tex]
Answer:

You can use the sine rule
a / sinA = b / sinB
Substitute the values in:
15 / sin112 = b / sin33
Multiply both sides by sin(33) to get b by itself
b = (15 / sin112) x sin33
Calculate this to get your answer of:
BC = 8.8 cm
2.
You can also use the sine rule here
sinA / a = sinB / b
Sub your values in:
sin84 / 32.4 = sin(y) / 21
Multiply both sides by 21 to isolate sin(y)
(sin84 / 32.4) x 21 = sin(y)
Calculate sin(y)
sin(y) = 0.6445975248
You now need to sin-1 this value to get u:

find: (i) the value of k,
(ii) the y-intercept.
Vine
Answer:
(i) k =1
(ii) y-intercept is 7
Step-by-step explanation:
Given line:
ky = kx + x + 7Divide all terms by k to get slope-intercept form of the line
y = (1 + 1/k)x + 7/kSince the gradient (slope) of the line is 2:
1 + 1/k = 21/k = 1k = 1The equation is now:
y = 2x + 7y - intercept is found when x = 0
x = 0 ⇒ y = 2*0 + 7 y = 7bc i have to ask a productive question what is ROYGBIV?

Bailey jog 3 km to her friends house from her friends house she jog 250m in all going to and from the park, then she jogged back home . How many meters did Bailey jogged in all
Answer:
The total distance is [tex]d_T = 6250 \ m[/tex]
Step-by-step explanation:
From the question we are told that
The distance from bailey start point to her friends house is [tex]d = 3 \ km = 3*1000 = 3000 \ m[/tex]
The distance covered going to and from the park is [tex]d_2 = 250 m[/tex]
The total distance covered is mathematically evaluated as
[tex]d_T = (2 * d_1) + d_2[/tex]
Substituting values
[tex]d_T = (2 * 3000) + 250[/tex]
[tex]d_T = 6250 \ m[/tex]
Dylan is wrapping a birthday present for his sister. The box the gift is in has a length of 6 inches, a width of 5 inches,
and a height of 3 inches. What is the minimum amount of wrapping paper Dylan will need to completely cover the
box?
TI
Answer:
126 square inches of wrapping paper
Step-by-step explanation:
To compute for the minimum amount of wrapping paper Dylan will need to completely cover the box, you have to compute the surface area of the box. The formula in getting the surface area of a rectangle is:
A = 2WL + 2LH + 2HW
Substituting the given measurements to the formula:
A = 2(5)(6) + 2(6)(3) + 2(3)(5)
A = 60 + 36 + 30
A = 126 square inches
Therefore, Dylan needs to purchase at least 126 square inches of wrapping paper to completely cover the box.

The sum of the interior angles of a polygon is 8280°.
How many sides does the polygon have?
The equation to find the sum of interior angles of a n-sided polygon is:
(n - 2) * 180
So, we don't know what n is but we can make it look like this:
(n - 2) * 180 = 8,280
Solve for n.
(n - 2) * 180 = 8,280
~Divide 180 to both sides
(n - 2) * 180/180 = 8,280/180
~Simplify
n - 2 = 46
~Add 2 to both sides
n - 2 + 2 = 46 + 2
~Simplify
n = 48
Therefore, the polygon has 48 sides.
Best of Luck!
