According to the question, Adelaide is the employee and she has to select a reward from four gifts. And those are 6 coffee mugs, 7 DVDs, 10 CDs and 3 gift baskets.
Now, calculate the probability that the gift is either a coffee mug or CD.
Let us assume, ‘G’ represents the gift card, ‘C’ represents the coffee mug and ‘D’ represents the CD.
The total number of items are [tex]4+6+7+10+3 = 30[/tex] items
P(G or C or D) = P(G) + P(C) + P(D)
[tex]= \frac{4}{30} + \frac{6}{30} + \frac{10}{30} = \frac{20}{30} = \frac{2}{3} = 67%[/tex]
Therefore , the probability to receive either a gift card or coffee mug or CD is [tex]67[/tex] percent.

Caylie's coin bank contains only dimes and nickels. The bank contains 46 coins. If 5 dimes and 2
nickels were removed, the total value of the coins would be $3.40. Find the number of nickels and the
number of dimes in the bank.
There were 29 nickels and 10 dimes in the bank.
We know that:
1 dime = 5 cents
1 nickel = 10 cents.
Also, $ 3.40 = 340 cents
Let the number of nickels be n and the number of dimes be d.
Now, we are given that:
5 dimes and 2 nickels were taken away.
So, total coins = 46 - 2 - 5 = 46 - 7
Total coins = 39
We get the equation:
n + d = 39
d = 39 - n
Now, we also know that:
5 d + 10 n = 340
d + 2 n = 68
Put the value of d, we get that:
39 - n + 2 n = 68
n = 68 - 39
n = 29
d = 39 - n
d = 39 - 29
d = 10
Therefore, we get that, there were 29 nickels and 10 dimes in the bank.

on the straight line choose a point preferably near centre and. place compass on the point and open to any distance, on the pencil side, draw a semi circle cutting the horizontal line at two points.
label the two points a and b
place compass on point and draw a smaller curve from that point above the center then do the same on other side
remember do not change the Size the compass was opened at for drawing the curves
the two new curves you drew should intersect, using ruler, draw a straight line vertically through intersection and center point

The distance traveled in each section will be 150 meters and 350 meters.
What is speed?The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
Speed = Distance/Time
From a simultaneous equation for: A cyclist completes a journey of 500 m in 22 seconds, part of the way at 10m/s and the remainder at 50m/s.
Let x distance be covered with velocity 10 m/s in time t₁ and the remaining distance (500 - x) covered with velocity 50 m/s in time t₂. Then the equation will be
t₁ + t₂ = 22 ....1
Then the time t₁ will be
10 = x / t₁
t₁ = x / 10
Then the time t₂ will be
t₂ = (500 - x) / 50
Put the time in equation 1, then we have
x / 10 + (500 - x) / 50 = 22
5x + 500 - x = 1100
4x = 600
x = 150 meters
And the remaining distance will be
500 - x = 500 - 150
500 - x = 350 meters
The distance traveled in each section will be 150 meters and 350 meters.

The formal for the valume v of a cylinder v=nr^(2)h,where is r is the radius of the base and h is height of the cylinder. solve the formal for h. then find the height of a cylinder with a valume of 36n cm^(2) and base with radius of 3 cm
The formula for the height of a cylinder is h = V / (π.r²) and the height of a cylinder with a volume of 36 cm³ and a radius of 3 cm is 4/π cm
Given a cylinder with a radius r and height h, then its volume is given by the formula:
V = π.r².h
Where:
V = volume
r = radius
h = height
To find the formula for the height, divide both sides by π.r²
V : π.r² = π.r².h : π.r²
or,
h = V / (π.r²)
The given parameters are:
V = 36 cm³
r = 3 cm
Substitute those parameters into the formula:
h = 36 / (π.3²)
h = 36 / (9π)

A solid cylinder has a diameter of 8.4 cm and a height of 12.0 CM. Calculate the volume of a cylinder.
Answer:
Volume = 665 cm³
Step-by-step explanation:
We can calculate the volume of a cylinder using the following formula:
[tex]\boxed{\mathrm{Volume = \pi r^2 h}}[/tex],
where:
• r = radius of cylinder
• h = height of the cylinder
In the question, we are told that the diameter of the cylinder is 8.4 cm. Since the diameter is twice of radius:
[tex]\mathrm{radius = 8.4 \div 2}[/tex]
[tex]= \bf 4.2 \: cm}[/tex]
We are also told that the height of the cylinder is 12.0 cm. Therefore, using this information, as well as the formula above, we can find the volume of the cylinder:
[tex]{\mathrm{Volume = \pi \times (4.2 \mathrm{\: cm})^2 \times 12.0 \mathrm{\: cm}}}[/tex]
[tex]= \pi \times 17.64 \mathrm{\: cm^} \times 12.0 \mathrm{\: cm}[/tex]
[tex]\approx \bf 665 \: cm^3[/tex]
Therefore the volume of the cube is 665 cm³.

What is an isosceles triangle ?In mathematics, an isosceles triangle is a triangle in which any of the two sides are equal. Or we can say that if a triangle has at least two sides of equal length then it is known as isosceles triangle. In geometry, isosceles triangle follow the property of congruency of triangles.

In the given question,
Let m∠B = m∠C = x , where m denotes measure of angle
therefore, m∠A = 3x
According to Triangle Angle-Sum Theorem,
m∠A + m∠B + m∠C = 180
