Can someone help me with these two!!!

Answer:

Step-by-step explanation:

t + u = 11 ----------- (1 )

10t + u = 10u + t - 9

10t + u - 10u - t = -9

10t - t + u - 10u = - 9

Combine like terms

9t - 9u = -9

Divide the entire equation by 9

[tex]\dfrac{9}{9}t-\dfrac{9}{9}u=\dfrac{-9}{9}[/tex]

t - u = -1  --------------(2)

Add equation (1) & (2) and so, u will be eliminated and we can find the value of t

(1)       t + u = 11

(2)      t  - u = -1

         2t     = 10

               t = 10/2

t = 5

Plugin t = 5 in equation (1)

5 + u = 11

    u = 11 - 5

u = 6

The original number is 56

Answer:

the slope is 0.

Explanation:

[tex]\hookrightarrow \sf \frac{2}{3} - 4y = 8[/tex]

[tex]\hookrightarrow \sf - 4y = 8- \frac{2}{3}[/tex]

[tex]\hookrightarrow \sf - 4y = \frac{24}{3} - \frac{2}{3}[/tex]

[tex]\hookrightarrow \sf - 4y = \frac{24-2}{3}[/tex]

[tex]\hookrightarrow \sf - 4y = \frac{22}{3}[/tex]

[tex]\hookrightarrow \sf y = \frac{22}{-12}[/tex]

[tex]\hookrightarrow \sf y = -\frac{11}{6}[/tex]

[tex]\hookrightarrow \sf y = -1\frac{5}{6}[/tex]

comparing with the formula: y =  mx + b

                               where m is slope and b is y-intercept.

we found that there is no x. so the value of slope will be 0x. slope = 0

Answer:

7.2

Step-by-step explanation:

14 = c

12= b

√(c² - b²)

12 x 12 = 144

14 x 14 = 196

196-144 = 52

√(52) = 7.21110255093

Answer:

x ≈ 7.2

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 12² = 14²

x² + 144 = 196 ( subtract 144 from both sides )

x² = 52 ( take square root of both sides )

x = [tex]\sqrt{52}[/tex] ≈ 7.2 ( to the nearest tenth )

The true statements are:

The square roots of numbers less than 1 are less than 1.

The square roots of numbers greater than 1 are greater than 1.

The square root is defined as a factor of a number when multiplied by itself, gives the original number.

The given numbers are 0.6 and 1.6. The square roots of given numbers are:

[tex]\sqrt{0.6} = 0.7745[/tex]

[tex]\sqrt{1.6} = 1.2649[/tex]

The first given number 0.6 is less than 1 and its square root is also less than 1. The second given number 1.6 is greater than 1 and its square root is also greater than 1.

Hence we can conclude that the square roots of numbers less than 1 are less than 1 and the square roots of numbers greater than 1 are greater than 1.

Answer:

28 is 160% of 17.5

Step-by-step explanation:

The value of number is, 17.5

That is, 28 is 160% of 17.5.

We have to give that,

To find 28 is 160% of which number.

Let us assume that,

A number = x

Hence, We can write as,

28 = 160% of x

Solve for x,

28 = 160/100 × x

Multiply by 100,

28 × 100 = 160x

2800 = 160x

160x = 2800

Divide into both sides by 160,

x = 2800/160

x = 280/16

x = 140/8

x = 70/4

x = 35/2

x = 17.5

Hence, The solution of the number is, 17.5

Answer: 4.2 kilometers after 3 minutes bc its 1.0729 kilometers after 1 minute. then it doubles every minute .

Step-by-step explanation: speed= distance divided by time method

The speed is the distance covered by an object at a particular time.  Millie speed after three minutes will be equal to 16 miles per hour.

The speed is the distance covered by an object at a particular time. Therefore, it is the ratio of distance and time.

[tex]\rm{Speed = \dfrac{Distance}{Time}[/tex]

Given that Millie doubles her running speed every minute. Also, her starting speed is 2 miles per hour. Therefore, her speed in different time period can be written as,

Speed after 1 min = 2 × 2 miles per hour

                              = 4 miles per hour

Speed after 2 min = 2 × 4 miles per hour

                              = 8 miles per hour

Speed after 3 min = 2 × 8 miles per hour

                              = 16 miles per hour

Hence, Millie speed after three minutes will be equal to 16 miles per hour.

The expression representing the amount of money that was raised for each member of the club is [tex]\dfrac{627.50 - 95.0}{m}[/tex] (in dollars)

When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get.

Thus, if 10 mangoes are there, and 2 people, then 10 ÷ 2 is the number of mangoes each person would get, which is 5.

Division, thus, can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.

Thus, [tex]a \div b = a[/tex] divided in b equal parts.

Also, we can write: [tex]a \div b = a \times \dfrac{1}{b}[/tex]

(it is since [tex]a = a \times 1[/tex] so [tex]a/b = 1 \times (a/b) = (1/b) \times a[/tex] )

Profit earned is the extra money which we make after deducing the cost price of the process we're doing.

So, we get:

Profit earned = Total amount earned - Amount spent initially for preparation to earn

P = Selling price (S.P.) = Cost price (C.P.)

For the given case, we're given that:

The money raised = Amount made by selling popcorn - amount costed to the club for getting popcorn

Money raised = $627.50 - $95.0

If it is given that: m = number of members in the considered club, then:

Money each member of the considered club will get = Money raised divided in equal m parts = [tex]\dfrac{627.50 - 95.0}{m}[/tex] (in dollars)

(we don't write symbols like of currency generally, and understand it from context.)

Thus, the expression representing the amount of money that was raised for each member of the club is [tex]\dfrac{627.50 - 95.0}{m}[/tex] (in dollars)

Cup 1 acts as a control group.

Step-by-step explanation:

Control group: The group used in the experiment by the researchers in which no change in the variable is done. It is then set as a benchmark for the groups which are being tested.

We are given 4 groups which are being experimented for the flotation of an egg in water.

Since in Cup 1, there is no addition of salt

So, there is no change in the variables.

So, by definition of control group .

So, cup 1 acts as a control group since there is no change in the variable .

Hence, the correct answer is Option 1.

Cup 1 acts as a control group.

Chickens have 2 legs and cows have 4 legs.

you mean, solve the inequality ...

it works the same way as with equations.

6x >= 24

x >= 4 (after dividing both sides by 6)

the only thing different is when you multiply (or divide) both sides by a negative number. then you have to turn the inequality sign around (< becomes >, <= becomes >=).

but other than that it is all as with regular equations.
