The variable is the number of hours Adi studied, the operation is addition, and the constant is 3. You can write the expression as h + 3 or 3 + h. To evaluate, substitute 8 in for the variable, h, and simplify. 8 plus 3 is 11. So Adi studied for 11 hours.

Consider 7×10^3. Write a pattern to find the value of the expression

kkurt [141]

Answer:

7*10*10*10 = 7000

7*10 = 70

70*10 = 700

700*10 = 7000

Step-by-step explanation:

The given expression is:

7*10^3

Here 10^3 means that 10 will be multiplied 3 times:

7*10*10*10 = 7000

How did we get 7000?

7*10*10*10 = 7000

7*10 = 70

70*10 = 700

700*10 = 7000

We can also say that there are 7 1000s in 7000....

The original price of a toaster is $18.00. If the toaster is marked down 25%, what is the new price?

Alla [95]

Answer:

$13.50

Step-by-step explanation:

First, we got to multiply $18 by 25% or .25

$18 x .25 = $4.50

Lastly, we just subtract $4.50 from $18.

$18 - $4.50 = $13.50

1 second = 2 megabytes

$1\frac{1}{2}\ seconds=3\ megabytes$

2 seconds = 4 megabytes

Step-by-step explanation:

Given,

Time taken to download 5 megabytes = $2\frac{1}{2}=\frac{5}{2}$ seconds

$\frac{5}{2}\ seconds = 5\ megabytes$

Multiplying both sides by $\frac{2}{5}$ to find unit rate

$\frac{2}{5}*\frac{5}{2}\ second = \frac{2}{5}*5\\1\ second = 2\ megabytes$

1 second = 2 megabytes

$1\frac{1}{2}\seconds = \frac{3}{2}\ seconds$

$\frac{3}{2}\ seconds = \frac{3}{2}*2$

$\frac{3}{2}\ seconds = 3\ megabytes$

$1\frac{1}{2}\ seconds=3\ megabytes$

2 seconds = 2*2 megabytes

2 seconds = 4 megabytes

If the measurment of the angles of a triangle are 3b,2b,and 4b then what is the smallest angle

d1i1m1o1n [39]

Given:

The measurement of the angles of a triangle are 3b,2b,and 4b.

To find:

The smallest angle.

Solution:

According to the angle sum property, the sum of all angles of a triangle is 180 degrees.

$3b+2b+4b=180^{\circ}$ [Angle sum property]

$9b=180^{\circ}$

Divide both sides by 9.

$b=20^{\circ}$

Now,

$3b=3(20^{\circ})=60^{\circ}$

$2b=2(20^{\circ})=40^{\circ}$

$3b=4(20^{\circ})=80^{\circ}$

Therefore, the smallest angle is 40 degrees.
