Answer:

The temperature on the first day was 10 °F.

Step-by-step explanation:

Let's find the temperature in every single step starting from the fourth day:

[tex]T_{4} = T_{3} - 6 F = 1 F[/tex]          

[tex] T_{3} = 1 F + 6 F = 7 F [/tex]

Then, the temperature of the third day was 7 °F

On the third day:

[tex] T_{3} = T_{2} - 10 F = 7 F [/tex]

[tex] T_{2} = 7 F + 10 F = 17 F [/tex]

Hence, the temperature on the second day was 17 °F.

Now, on the second day:

[tex]T_{2} = T_{1} + 7 F = 17 F[/tex]  

[tex] T_{1} = 17 F - 7 F = 10 F [/tex]

Therefore, the temperature on the first day was 10 °F.

I hope it helps you!                        

Answer: 12.9 square km

Step-by-step explanation: 4.3 x 3 =12.9

Answer:

He can buy 3 scoops of salts and 4 scoops of pepper or 4 scoops of salts and 3 scoops of pepper spent maximum.

Step-by-step explanation:

Given that:

The cost of salt = 50 cents / scoop =$ 0.5 / scoop

The cost of pepper =75 cents / scoop = $ 0.75 / scoop

Let he buys x scoops of salt and y scoops of pepper.

As he plans to bring home no more than 8 scoops of seasoning, so

[tex]x+y\leq8\cdots(i)[/tex]

The total cost of x scoops of salt and y scoops of pepper = 0.5x+0.75y

As he wants to spend less than $5, so

[tex]0.5x+0.75y<5 \\\\ \Rightarrow 50x+75y<500 \\\\\Rightarrow 2x+3y <20\cdots(ii)[/tex]

Here, [tex]x\geq 0, y \geq 0[/tex] and x,y are counting numbers.

On plotting the graph of equations (ii) and (ii), the possible solution is the integral values in the shaded as shown in the figure.

The maximum possible integral values, for expances less than $5, are (x,y)=(3,4), (4,3).

Hence, he can buy 3 scoops of salts and 4 scoops of pepper or 4 scoops of salts and 3 scoops of pepper to spent maximum.

Answer:

0.0025551

Step-by-step explanation:

Given that:

Mean (m) = 40000

Standard deviation (s) = 2500

P(x < 33,000) :

USing the relation to obtain the standardized score (Z) :

Z = (x - m) / s

Z = (33000 - 40000) / 2500 = - 2.8

p(Z < -2.8) = 0.0025551 ( Z probability calculator)

Probability of Tyre wagering out before mileage limit is reached = 0.0025551

Answer:

C) 140

Step-by-step explanation:

We can see from the diagram that mMEF + mDEM = mDEF because they share the same lines.

Therefore:

69x + 2 + 34 = 2 + 86x

Now we can solve this equation.

First we can eliminate the +2 from each side as they will cancel:

69x + 34 = 86X

And then rearrange to solve for x:

34 + 69x - 69x = 86x - 69x

34 = 17x

34/17 = 17x/17

x = 2

Now that we have the value for x, we can substitute it into the original equation:

mMEF = 69(2) +2

mMEF = 138 + 2

mMEF = 140

Therefore the correct answer is C) 140.

Hope this helped!

4 if rong so so sorry

Step-by-step explanation:

Answer:

0.1875, or 3/16

Step-by-step explanation:

The formula for density is mass/volume.

I hope this helps :)

Answer:

[tex]{\boxed {\sf \frac{3}{16} \ g/cm^3}}[/tex]

or

[tex]\boxed {\sf 0.1875 \ g/cm^3}}[/tex]

Step-by-step explanation:

Density can be found by dividing the mass by the volume.

[tex]\rho= \frac{m}{v}[/tex]

The mass of the cork is 3 grams and the volume is 16 cubic centimeters.

[tex]m= 3 \ g\\v= 16 \ cm^3[/tex]

Substitute the values into the formula.

[tex]\rho = \frac{3 \ g }{16 \ cm^3}[/tex]

Divide.

[tex]\rho=\frac {3}{16} \ g/cm^3[/tex]

[tex]\rho=0.1875 \ g/cm^3[/tex]

The density of the cork is 3/16 or 0.1875 grams per cubic centimeter.

Answer:

This year, Juanita will have to use $75.

Step-by-step explanation:

Because if 2 shirts is $15, 4 shirts will be $30. $45 is $15 more than $30, so the increase is $15. 2*4 is 8, so that will make it 15*4=60. 60+15=75.

Answer: {(0, 1), (1, 5), (2, 9)}

Step-by-step explanation:

Given linear equation: y-1=4x which can be rewritten as

y=4x+1

To find the set which represents possible inputs and outputs of the function. Let's check all the options

A. {(1, 4), (2, 8), (3, 12)}

at x=1

y=4(1)+1

⇒y=5≠4

Thus this set is not the required set.

B. {(4, 1), (8, 2), (12, 3)}

at x=4

y=4(4)+1

⇒y=16+1=17≠1

Thus this set is not the required set.

C.{(0, 1), (1, 5), (2, 9)}

at x=0

y=4(0)+1

⇒y=1

Thus this set is the required set represents possible inputs and outputs of the function.

D. {(1, 0), (5, 1), (9, 2)}

at x=1

y=5≠0

Thus this set is not the required set.

Step-by-step explanation:

88n+20n

=108n

Step-by-step explanation:

5t-3(7t+1) < 93

Remove the parentheses

5t-21t-3 < 93

-16t < 93+3

-16t < 96

Divide both sides by 16

-t<96/16

-t<6

t > -6

Answer: The inequality t < 6 is the correct answer.

Step-by-step explanation:

5t - 3 (7t + 1) < 93​ <--- This is the original equation.

5t + (7t + 1) - 3 < 93​ <---- Use commutative property.

16t - 3 < 93 <--- Simplify

16t - 3 + 3  < 93​ + 3 <---- Add 3 to both sides,

16t < 96 <--- Simplify and do addition.

[tex]\frac{16t}{16}[/tex] < [tex]\frac{96}{16}[/tex] <--- Divide both sides by 16.

t < 6 <--- is the answer to the inequality.

Hope this helps! :D

quotient im pretty sure i haven't been in 6th grade in 2 years so sorry if im wrong

Step-by-step explanation:

The answer is x = 6

Let us first define x to be the number of hours of riding lessons she can take.

X = Hours of lessons

Now, she has $200, she needs to pay $20 for grooming supplies, and the lessons cost $30 an hour. We to find the maximum amount of hours of lessons she can take, so in other words, we want to make her broke. To do this, we first convert the words into an equation:

200 - 20 - 30x = 0

Simplifying, we get

180 = 30x

x=6
