Lily likes to collect records last year she had
15 records in her collection this year she
has 24 records what is the increase of her
collection

Answers

Answer 1
the answer would be she had an increase of 9 records this year. so she had 15 last year and this year 24. to get the increase you should subtract the amount she had this year (24) by the amount she had last year (15). this equals 9.
Answer 2
The increase is 9. 24-15 or 15- 24 can be used to solve this. The absolute value of both of them is 9. So the answer is 9 hope this helped :p

Answer:

About 2.38 square feet of extra fabric: 1.25 of dark blue and 1.13 of light blue

Need $13.75 to complete template for white fabric

Step-by-step explanation:

Template requires 18 square feet of white, 20 square feet of light blue and 21 square feet of dark blue.

She has more than enough for both shades of blue fabric.

She needs 5.85 square feet more of white fabric

Since it is $2.35 per square feet of white fabric, 2.35 * 5.85 = $13.75.

It will cost her $13.75 for more white fabric

If one side of a right triangle is 12 feet long and the hypotenuse of the triangle is 7, find the length of the other side of the right triangle. Round to the nearest hundredth.
I might give you a brainliest if your answer is correct and you have a good explanation.

Answers

Answer:

9.74 feet

Step-by-step explanation:

the formula for finding a hypotenuse is [tex]a^{2} + b^{2} = c^{2}[/tex]. We can rearrange that to get: [tex]c^2 - b^2 = a^2[/tex]. So: 49 + b^2 = 144. We get the square root of 95, AKA around 9.74.

A beaker is completely filled with water
​A ball in the shape of a sphere ​with radius 4 centimeters is placed in the beaker and is completely ​submerged, causing the volume of water equal to the ball’s volume to ​overflow.
​​All of the water that overflows is collected in a funnel in the ​shape of a cone.
​​When the funnel is held vertically, the surface of the ​water collected forms a circle of radius 4 centimeters.
​What is the ​height of the cone formed by the water in the funnel?
​​Round your ​answer to the nearest inch.

Answers

Answer:6.3 in.

Step-by-step explanation:

Given

Radius of sphere [tex]r=4\ cm[/tex]

When ball is immersed in beaker, it causes the water to flowout of beaker which is collected in the conical vessel

Such that amount of water equivalent to sphere volume is collected in it.

volume of ball

[tex]V_s=\frac{4\pi }{3}r^3[/tex]

[tex]V_s=\frac{4\pi }{3}\times 4^3[/tex]

[tex]V_s=\frac{256\pi }{3}\ cm^3[/tex]

Now volume of water collected is in shape of cone then volume of cone

[tex]V_c=\frac{\pi }{3}r^2h[/tex]

and [tex]V_s=V_c[/tex]

[tex]\frac{256\pi }{3}=\frac{\pi }{3}(4)^2\times h\ quad [\text{h=height of cone formed}][/tex]

[tex]h=4^2=16\ cm\approx 6.29\approx 6.3\ in.[/tex]

What is the constant in 15-8y
A 15
B 8

D -15

Answers

Simplifying
15 + 8y = 15

Add '-15' to each side of the equation.
15 + -15 + 8y = 15 + -15

Combine like terms: 15 + -15 = 0
0 + 8y = 15 + -15
8y = 15 + -15

Combine like terms: 15 + -15 = 0
8y = 0

Solving
8y = 0

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Divide each side by '8'.
y = 0

Simplifying
y = 0

Helpppppppp. Jason inherited a piece of land from his great-uncle. Owners in the area claim that there is a 45% chance that the land has oil. Jason decides to test the land for oil. He buys a kit that claims to have an 80% accuracy rate of indicating oil in the soil. What is the probability that the land has no oil and the test shows that it has oil? A. 0.09 B. 0.11 C. 0.36 D. 0.44

Answers

Answer:

Jason Inherit a land with a 45% chance of having oil.

Step-by-step explanation:

 The probability of the land having oil is = P ( O) = 45 /100

The probability of the land having oil is= Q(O ) =55/100

The machine has an accuracy of 80%. This suggests that 8 out of 10 times the machine will give a wrong reading.

The probability of the correct reading is=  P(M)=80/100

The probability of the incorrect reading is=Q(M)=20/100

The case when the machine predicts there is no oil and there is indeed oil can be calculated:Probability=Probability of oil present  ×  probability of the incorrect reading

Probability=P(O) x Q(M)

Probability=45/100 x 20/100

Probability=9/100

The probability of the test predicting no oil in land and the land has oil is  0.09 or 9%

A right cylinder has a diameter of 40 mm in a high of 30 mm as soon what is the volume of the cylinders

Answers

________________________________

Hey!!

Solution,

Diameter=40 mm

Radius=40/2=20mm

Height=30mm

Volume of cylinder=?

Now,

Volume of cylinder=pi (r)^2 h

= 3.14*(20)^2*30

=3.14*400*30

=37,680 mm^3

So the right answer is of option A

hope it helps

Good luck on your assignment

__________________________________

Answer:

37,680 mm3

Steps:

Formula: Volume = Area * height

1:    = (pi/4)*D^2 * h

2:   = (pi/4)*(40)^2 * 30  

3:    = 37,680 mm3

Description:

We know that r is the radius and h is the height. So the

radius of the cylinder going to be r=40/2=20mm

Height of cylinder: 30mm

Meaning when you add up all the numbers answer will come as  37,680 mm3.  So a is the right answer for this question.
