3(4)+3(2+7)= ×(4+9) what number is missing to make this equation true​

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:

5+4x=25

Step-by-step explanation:

You already know you bought 1 $5 magazine so that is the constant. And the question asks how many erasers you bought to equal $25. So to write the equation you know it equals 25 and the 5 is constant, if each eraser is $4 then the x goes with the 4 making it, 5+4x=25

Answer:

The answer to the far left/the Blue Answer.

Step-by-step explanation:

The reason why is because if 1 magazine was the price of $5, that would mean that the total of the erasers AND the magazine equals 25 dollars, as said in the statement. This means that when subtracting 5 dollars from 25 dollars, there are 20 dollars left. This means that if there were 4 erasers, that means that 20 dollars divided 4 erasers equals 5 dollars. This means that each eraser costs 5 dollars, making the Blue Answer/Statement true.

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:

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:

115.7 km/h

Step-by-step explanation:

velocity = distance/time

velocity = (0.9 km)/(28 s) = 0.032143 km/s

The velocity is 0.032143 k/s. The question is answered, but since km/s is not a common unit of speed, we can convert to a more common unit of speed such as km/h.

velocity = (0.9 km)/(28 s)[(3600 s)/(1 h)] = 115.7 km/h

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)

R=interest rate=4%=0.04

T=time=6 months=0.5 year

Simple interest=P×R×T

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

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:

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:

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€

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:

It will take 4 years

Step-by-step explanation:

Here, given the exponential equation that approximates the cost of a car after a certain amount of time, we are tasked with calculating the amount of time it will take to be worth a certain amount.

The exponential equation that approximates the cost of the car is given as;

V = 2,000(0.8)^x

Now, our V = 820 but we want to calculate x which gives the number of years. Substituting this value of V, we get;

820 = 2000(0.8)^x

divide through by 2000

0.41 = 0.8^x

Take the log of both sides

log 0.41 = log 0.8^x

log 0.41 = xlog 0.8

x = log 0.41/log 0.8

x = 3.99 which is approximately 4 years
