b) 25 20 15 10 5​

Answer:

Scientific notation simply refers to the process of expressing long numbers in decimal.

Answer:

Step-by-step explanation  

Scientific notation is a way of writing numbers that is often used by scientists and mathematicians to make it easier to write large and small numbers. A number that is written in scientific notation has several properties that make it very useful to local scientists. It makes very large numbers into smaller numbers using decimals and exponents.

Answer:

The answer is, 8.5

Step-by-step explanation:

1.25×8=10

10-1.5=8.5

Answer:

230

Step-by-step explanation:

Okay, so if Lidia got 75% means that Henry got 25%, right?

Then Lidia got 50% more than Henry did. So that 460 = 50%

So Henry got 25% which is 460/2 = 230 snow globes

Answer:

The depth of oil in the tin is 9cm

Step-by-step explanation:

The first thing we need to do here is to calculate the volume of the cylindrical tin.

Mathematically, that would be;

V = pi * r^2 * h

now, r = d/2 = 12/2 = 6cm

h = 14 cm

Thus the volume would be;

V = 22/7 * 14 * 6^2 = 1,584 cm^3

Now, to find the the depth of the tin, we have to realize that the content of the cylinder should fill in the tin to a particular height.

Now let’s say the height of the tin is x, this means its volume which is l * b * h = 16 * 11 * x = 176x

So the depth x would be;

176x = 1584

x = 1584/176 = 9 cm

Answer:

Step-by-step explanation:

To find the value of x, solve the equation. Do this by rearranging the equation to make x the subject.

Answer:

x=32761 /4

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4x+7=32768

Step 2: Subtract 7 from both sides.

4x+7−7=32768−7

4x=32761

Step 3: Divide both sides by 4.

Answer:

52

Step-by-step explanation:

If ABCD ~ EFGH

AND AB = 15 and EF = 18 and ABCD = 40

then

each side of ABCD should be 3cm less then side of EFGH

AB + BC + CD + DA = 40

AB + 3 + BC + 3 + CD +3 + DA + 3= P(EFGH)

40+12 = 52 = P(EFGH)

Answer:

it would be 10

Answer:

g(x)=2(x-4)(x+3)​

Step-by-step explanation:

Answer:

Hello,

g(x) = 2 (x + 3) (x - 4)

Step-by-step explanation:

g(x) = 2x²- 2x - 24​

⇔ g(x) = 2 (x² - x - 12)

⇔ g(x) = 2 ((x - 1/2)² - (1/2)² - 12)

⇔ g(x) = 2 ((x - 1/2)² - 12.25)

⇔ g(x) = 2 ((x - 1/2)² - 3.5²)

⇔ g(x) = 2 ((x - 1/2)² - (7/2)²)

⇔ g(x) = 2 (x - 1/2 + 7/2) (x - 1/2 - 7/2)

⇔ g(x) = 2 (x + 3) (x - 4)

Answer:

[tex]3x-7y[/tex]

Step-by-step explanation:

[tex]9x-7y-6x[/tex]

[tex]9x+-7y+-6x[/tex]

[tex]9x+-6x+-7y[/tex]

[tex]3x+-7y[/tex]

Answer:

3x-7y

Step-by-step explanation:

9x and 6x are like terms

We subtract 6x from 9x because it is a negative

9x-6x= 3x

7y is also negative that's why the answer is 9x-7y

But you can also do -7y + 3x

It doesn't matter it's still the same

Hope this helps!

Answer: Isosceles Triangle

Step-by-step explanation:

Looking at this problem, we can easily say this this is a right triangle, by looking at the labeled angle. This questions asks for you to look at the angles and side lengths. Because the sides are both equal in length, this is an isosceles triangle.

Step-by-step explanation:

x³ - 4x = 0

x (x² - 4) = 0

x (x + 2) (x - 2) = 0

Thus the answer is (b) (-2 , 0) , (0 , 0) , (2 , 0)

Answer:

C

Step-by-step explanation:

We shall be using the formula for simple interest to calculate this

Mathematically;

I = PRT/100

where P is the amount deposited = $8,500

R is the rate = 4%

and T is the time which is 2 years

Plugging these values, we have

I = (8500*4*2)/100 = $680

Answer:

A1= 10×15=150

A2= 5²×3.14/2=39.3

so the A total is 150+39.3=189.3

answer 19-11+(-17)+(-19)+11= -17

Answer: 0.12

Step-by-step explanation:

An exponential decay can be written as:

C(t) = A*r^t

Where A is the initial amount of cookies, A = 100

r is the rate that we are searching.

t is time in minutes, we know that at t= 0m

C(0) = 100*r^0 = 100

so at t = 0m we have 100 cookies.

now, we know that at t = 15m we have.

C(15s) = 100*r^(15m) = 15

r^15 = 15/100 = 0.15

r = (0.15)^(1/15) = 0.88

So the rate at which the cookies decrease is 0.88, and 1 - r = 0.12 is the rate at which the kids eat the cookies (meaning that the students ate 12% of the cookies per minute), so the answer is 0.12

Answer:

C. 1 hundred 9 tens 15 ones

Step-by-step explanation:

Which shows how to regroup 205 to subtract 205-147?

A. 2 hundreds 9 tens 15 ones

B. 1 hundred 10 tens 15 ones

C. 1 hundred 9 tens 15 ones

D. 1 hundred 8 tens 15 ones

To regroup 205, you can write 1 hundred, 9 tens, and 15 ones or option C.

Since 100+90+15=205.

Answer:

y = 2x or x = 1/2y or if you would like numerical values then x = 3, y = 6 and z=4

Step-by-step explanation:

x : y = 1 : 2

y : z = 3 : 2

If x : y = 1 : 2 then we know that 1y = 2x ∴ y = 2x or x = 1/2y

If y : z = 3 : 2 then we know that 3z = 2y ∴ z = 2/3y

Answer:

I think y is 2 as well as 3

Answer:

Step-by-step explanation:

This models the standard form of an exponential equation:

[tex]y=a(b)^x[/tex], where a is the intial value and b is the growth rate. The number in our function that holds position a is 1200. So the initial population is 1200.
