Answer:

1) 7/8

2) 17/12 = 1 5/12

3) 53/12 = 4 5/12

Step-by-step explanation:

1) 3/8 + 1/2 = 3/8 + 4/8 = 7/8

2) 2/3 + 3/4 = 8/12 + 9/12 = 17/12 = 1 5/12

3) 4 2/3 - 3/12 = 14/3 - 3/12 = 56/12 - 3/12 = 53/12 = 4 5/12

This would be the average value of R(x) between 10 m and 50 m :

[tex]\displaystyle \frac1{50\,\mathrm m - 10\,\mathrm m} \int_{10\,\rm m}^{50\,\rm m} kx^2 \, dx[/tex]

The average intensity of radiation between 10 meters and 50 meters from the source is 1033.33 k.

It is the reverse of differentiation.

The intensity of radiation at a distance x meters from a source is modeled by the function given by

R(x)=kx²

where k is a positive constant.

The average intensity of radiation between 10 meters and 50 meters from the source will be

[tex]\rm Average \ intensity = \dfrac{1}{50 - 10} \int_{10}^{50} \ kx^2 \ dx\\\\\\Average \ intensity = \dfrac{k}{50 - 10} [ \dfrac{x^3}{3} ]_{10}^{50}\\\\\\Average \ intensity = \dfrac{k}{40} [ \dfrac{50^3}{3} - \dfrac{10^3}{3} ]\\\\\\Average \ intensity =1033.33k[/tex]

Answer:

37.2 cm

Step-by-step explanation:

Perimeter of a rectangle = 2*(length + breadth)

==> perimeter = 2*(12 + 6.6)

= 2*(18.6)

= 37.2 cm

Answer:

[tex] \red{37.2 \: cm}[/tex]

Step-by-step explanation:

The formula to find the perimeter of a rectangle is:

[tex] \text{perimeter} = 2(l + w)[/tex]

Given that,

length = 12cm

width = 6.6cm

Let us find the perimeter of the rectangle now.

[tex] \text{perimeter} = 2(l + w) \\ \text{perimeter} = 2(12 + 6.6) \\ \text{perimeter} = 2 \times 18.6 \\ \text{perimeter} = 37.2 \: cm[/tex]

Answer:

3 units to the right and 1 unit up

Step-by-step explanation:

Pick one of the points on the original figure ABCD.

For example, let's pick point C.

The coordinates for point C are (2, 1)

The coordinates for the translated point C, i.e. point C' are (5, 2)

x-coordinate change = 5 - 2 = 3 ⇒ 3 units to the right

y-coordinate change = 2 - 1 = 1  ⇒ 1 unit up

Alternatively, just count the squares as 1 square = 1 unit

Answer:

you answer is correct

Step-by-step explanation:

they is no problem with your answer.

Answer:

No.

Step-by-step explanation:

For there to be a equal sign, it will mean that both sides will have to have the same exact amount. If it is expressions on both sides, then the expressions must, when combined, equal to each other.

In this case, there is not given operation that will allow for both numbers to equal each other, and 17.8 is 10 less than 18.8, therefore it is not reasonable.

17.8 ≠ 18.8

The number of people in the room is 91.

The first step is to determine the total number of chairs in the room. In order to determine this value, divide the fraction of the unoccupied chairs by the number of empty chairs.

8 ÷ 1/8

8 x 8 = 64

Number of people sitting on the chairs = 64 - 8 = 52

Number of people in the room = 52 ÷ 4/7

Answer:

15/40 which simplified is 3/8

Step-by-step explanation:

To solve this equation, we first have to turn all mixed numbers into improper fractions so we can add and subtract them

When we do this we get, 35/5 - (11/4 + 31/8)

Since there is a negative (-) sign before the parentheses, we automatically sub in a -1 in there and we distribute

Now we have 35/5 - 11/4 - 31/8

We can’t subtract this directly since they all have different denominators, so we have to change them to a common denominator

The common denominator of 5 4 and 8 is 40 so we multiply both the numerators and denominators by whatever number it is so the denominators are 40

This gets us to 280/40 - 110/40 - 155/40

When we subtract all of this, we get…

15/40 which can be simplified to 3/8

5z^4

Step-by-step explanation:

1. 2w+ 16w= 18w

2. when multiplying exponents just add the exponents giving you p^8

3. 7k - 3k= 4k

4. 5z also equals 5z^1 and just like problem two you will just add the exponents but you will leave the coefficient( 5 alone) giving you 5^4
