Answer:

0.5 Inches

Step-by-step explanation:

1/16=.0625 which is about .1 for estimating purposes

.1 on Saturday + .4 on Sunday = .5 inches of rain over the two days

Answer: 1.5 inches

Step-by-step explanation:

"The amount of rain that fell over two days" means the sum of the two amounts of rain that fell on Saturday and Sunday.

[tex]1\frac{1}{16} +0.4=1\frac{10}{160} + \frac{4}{10} = 1\frac{10}{160} + \frac{64}{160} = 1\frac{74}{160}[/tex]

This number is close to [tex]1\frac{80}{160}[/tex], which is 1.5 inches.

Answer:

702 emails

Step-by-step explanation:

Given data

Average personal emails received monthly = [tex]780 emails[/tex]

Average work emails received monthly[tex]= 760 emails[/tex]

      We are required to solve for the new amount of emails Joe will be receiving after changing his address, to find this value we need to solve for the depreciation of his personal mails.

      After solving for the depreciation , we then need to subtract the depreciation from the initial number of mails to get the new number of mails.

let us solve for 10% depreciation.

[tex]depreciation= \frac{10}{100} *780\\depreciation=0.1*780= 78 emails[/tex]

The new number of mails

[tex]= initial number of mail- depreciation\\ =780-78= 702 emails[/tex]

Joe will be receiving an average of 702 emails in his personal account monthly

Answer:

28043.3 [tex]m^{3}[/tex]

Step-by-step explanation:

Formula for volume of a hemisphere can be termed as:

[tex]V = \dfrac{2}{3} \pi r^{3}[/tex]

where [tex]r[/tex] is the radius of hemisphere

Please refer to the figure attached for the sample figure of a hemisphere.

We are given here, diameter of hemisphere = 47.5 m

Relation between diameter and radius is given as :

[tex]r = \dfrac{d}{2}[/tex]

where, [tex]r[/tex] is the radius and

[tex]d[/tex] is the diameter.

So, [tex]r = \dfrac{47.5}{2}\ m[/tex]

Volume is:

[tex]V = \dfrac{2}{3} \pi (\dfrac{47.5}{2})^3\\\Rightarrow \dfrac{2}{3} \times 3.14 \times (\dfrac{47.5}{2})^3\\\Rightarrow 28043.3\ m^3[/tex]

Hence, volume of given hemisphere is 28043.3 [tex]m^{3}[/tex].

Answer:

  140

Step-by-step explanation:

When working HCF and LCM problems, I like to think in terms of this little diagram:

  (a [ b ) c]

It shows me one of the numbers is ab, the other is bc, the HCF is b and the LCM is abc. "a" and "c" must be relatively prime for "b" to be the HCF.

__

Here, we're given ...

  b = 20

  ab = 320

  abc = 2240

Then ...

  c = abc/(ab) = 2240/320 = 7

  x = bc = 20(7) . . . . . . equivalently, x = (abc·b)/(ab) = (2240·20)/320

  x = 140

Answer:

139

Step-by-step explanation:

First, find all the faces that you must find the areas of. In this case, you need to find the areas of two triangles and three rectangles.

In this triangular prism, the base is one triangle. If the area of the base is 7.75, we can assume that that holds true for both bases, and multiply 7.75 by 2 in order to find the area of both triangles.

Now find the area of each of the three rectangles by multiplying their individual heights and bases by each other. You should get 38, 47.5, and 38 as the areas of the rectangles.

Now add all the individual area's together. (They're bolded for clarity).

Answer:

There is a outlier and a negative relationship.

Step-by-step explanation:

negative shows that it goes from top to bottom and left to right (unless some numbers are switched around.) with this we also notice that there is a dot that is away from the group (the outlier)

Answer:

the price of the socks is 22€

Step-by-step explanation:

To find the value of a pair of socks you first write an algebraic expression for the situation of the problem.

Maria has 52€, she spent 23€ and also she spent in buying the three pairs of socks. You can chose x as the price of one pair of socks, then, Maria spent 3x. In the end Maria is owd 23€.

If you subtract 23€  and 3x to 52€  you obtain a negative value of -13€ . That is:

53 - 3x = -13    (1)

From the last equation you obtain x:

- 3x = - 13 - 53

-3x = - 66

x = (66/3) = 22

hence, the price of the socks is 22€

[tex]9x^2-5x-7[/tex]

Step-by-step explanation:

Step-by-step explanation:

Answer:

[tex]f(3) = f(3 - 2) \times f(3 - 1)[/tex]

[tex]f(3) = f(1) \times f(2)[/tex]

[tex]f(3) = 4 \times 25[/tex]

[tex]4 \times 25 = 100[/tex]

12 is the measure of the value of f(3).

Based on the given information, we have f(1) = 4 and f(2) = 25.

To determine the value of f(3), we will use the recursive formula

f(n) = f(n - 2) * S(n - 1), where:

S represents the successor function.

Determine f(3):

f(3) = f(3 - 2) * S(3 - 1)

f(3) = f(1) * S(2)

f(3) = 4 * 3

f(3) = 12

Therefore, the value of f(3) from the sequence is 12.

Answer:

yes, they're equivalent

Answer:

Yes ,they are equivalent.

Step-by-step explanation:

2(n + 5) + 4(n + 5) ; here since n+5 is a common factor so we can factor it out :

2(n + 5) + 4(n + 5) = (n + 5)×(2 + 4)

                             = (n + 5)×(6)

Answer:

BC ≈ 10.4 mm(1 decimal)

Step-by-step explanation:

The question forms a right angle triangle. The angle BAC = 90°. The side AB = 7.3 mm and the side CA = 7.4 mm. The length of BC can be solved below.

AC = opposite side = 7.4 mm

AB = adjacent side = 7.3 mm

BC = hypotenuse = ?

Using pythagoras theorem we can find the longest side which is the hypotenuse

c² = a² + b²(pythagoras formular)

where

c = hypotenuse side

BC² = 7.4² + 7.3²

BC² = 54.76 + 53.29

BC² = 108.05

square root both sides

BC = √108.05

BC = 10.3947101931

BC ≈ 10.4 mm(1 decimal place)

Answer:

30 inches/4=7.5 inches

Step-by-step explanation:

Answer:

7.5 inches

Step-by-step explanation:

Since we need 4 magnets and we use 5/6 yards, it is easier to convert 5/6 yards into inches first. One yard=36 inches, so we used overall of 30 inches for every magnet. Simply divide 30/4 to get 7.5 inches

Answer:

1. y = -3x + 5

2. y = 1/4x - 2

Step-by-step explanation:

y=mx+b

1. 5 = -3(0) + b, so b = 5

y = -3x + 5

2. (-2-(-1))/(0-4) = -1/-4 = 1/4

-2 = 1/4(0) + b, so b = -2

y = 1/4x - 2

Answer: -3x+5
