Answer:

15.52 is the perimeter

Step-by-step explanation:

Length(l)=5.06in

Breadth(b)=2.7in

Now,

Perimeter=2(l+b)

[tex]Perimeter=2(5.06in+2.7in)\\\\Perimeter=2(7.76in)\\\\Perimeter=15.52in[/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:

No

Step-by-step explanation:

They are 7 years apart. Therefore, the only age where Pedro will be twice as old is his brother is the age 14 because 7 is half of 14.

Hi!

Your answer is No.

This is because they are seven years apart in age. The only way for Pedro to be twice as old as his brother would be for

a + 7 = 2a

('a' is Pedro's brother's age)

Now, if we subtract a from both sides in the top equation, we get:

7 = a

Let's make a system of equations:

144/x=y

168/(x+5)=y

So,

144/x=168/(x+5)

Solving using cross multiplication,

x=30

So, her average speed for driving 144 miles was 30 miles per hour.

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

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]

10 is average of this

The smallest possible average of five distinct positive even integers is 6.

To find the smallest possible average of five distinct positive even integers, to minimize the values of those integers.

The smallest distinct positive even integers start from 2, 4, 6, 8, 10, and so on.

To minimize the average, to choose the five smallest even integers. So, the five distinct positive even integers are:

2, 4, 6, 8, 10

To calculate the average, sum up these five integers and divide by 5:

Average = (2 + 4 + 6 + 8 + 10) / 5

Average = 30 / 5

Average = 6

So, the smallest possible average of five distinct positive even integers is 6.

Answer:

x = 124.5

Step-by-step explanation:

adjacent given 88 and asked us to find x, which is a hypotenuse.

using the cosine formula:

[tex]\frac{adjacent}{hypotenuse} = cos(y)[/tex]

[tex]\frac{88}{hypotenuse} = cos(45)[/tex]

[tex]hypotenuse = \frac{88}{cos(45)}[/tex]

[tex]hypotenuse = 124.5[/tex]

Given :-

To Find :-

Solution :-

The given expression is ,

→ 5³ .

As we know that if there is aⁿ , where n is the power then we have to multiply the number at the base n times . Hence here ,

→ 5³ can be rewritten as

→ 5 * 5 *5

Simplify ,

→ 125

Hence the required answer is 125 .

I hope this helps.

Let us evaluate 5³

Explanation:

[tex]5³ = 5 × 5 × 5 = 125[/tex]

5³ can also be understood as 5 cubed.

Whenever a number (x) is multiplied by itself three times, then the resultant answer is known as the cube of that number.

Thus, 5 to the 3rd power is equal to 125

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
