Answer:

3mi/hr , 3 miles per hour or 3mph

Step-by-step explanation:

so you want to find how manu milesin an hour.

first you need to gind how many miles in jsut 1/8 of the hour

so what we have is for 3/8 of an hour so divide what we have by 3

9/8 divided by 3 = 3/8 of a mile in 1/8 of an hour.

multiple this by 8 to get what equals in 1 hr

3/8*8 = 24/8 simplified to 3.

3 miles per hour

Answer:

5.)

15.36+x=32.11

15.36+x-15.36=32.11-15.36

x=32.11-15.36

x=16.75

6.)

-2(a-3b+c)

-2a+6b-2c

7.)

3a+15y-5a=-a+2(3-a)

-2a+15y= -a+6-2a

-2a+15y=-3a+6

-2a+15y+2a=-3a+6+2a

15y=-a+6

15y/15=-a+6/15

y=-a+6/15

Answer:

Domain: {x|-4<=x<=4}

Step-by-step explanation:

Domain reffers to the set of the 1st elements, so the x values. In the image we see the ellipse go through both x and y axis but since the question is asking for domain and NOT range (range meaning y values) we can conclude that we need the x values, those being -4 and 4.

where m = slope.

Plug in the data:

Answer:

Acute

Step-by-step explanation:

Answer:

acute

Step-by-step explanation:

if the angle is less than 90 degrees, it is acute. if the angle is larger than 90 degrees, it is obtuse. if an angle is exactly 90 degrees it is a right angle. angles 3 and 6 are smaller than 90 degrees so they are acute

Answer:

x-6/x²-x-30

Step-by-step explanation:

(x-6)(x+5)

x²-x-30

when you factor out  x-6 you have a removable discontinuity and you have x+5 as your denominator and that would be the vertical asymptote since you can have a 0 as your denominator the V.A. would be x = -5.

Answer: B 124

Step-by-step explanation:

When you have problems like this, you would add the two angles inside the triangle to get the measurement for the outer angle. so 37 + 87 equals 124.

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

Answer:

2 OR 20

Step-by-step explanation:

Answer:

1) -275C

2) Less than or equal to -11C/min.

Step-by-step explanation:

Currently, the sample is 3C.

So, in order for our sample to freeze, it must decrease to -272C.

Part A)

So, to find how much the temperature must change, we can subtract the current temperature from the desired temperature.

So:

[tex]-272-3=-275\textdegree C[/tex]

Therefore, the temperature must change by -275C.

The negative tells us that the temperature must decrease by at least 275C in order to ensure that the helium freezes.

Part B)

Let t represent the temperature change per minute.

We know that the change must be -275C or greater.

Therefore, we can write the following inequality:

[tex]25t\leq-275[/tex].

We can divide both sides by 25. So:

[tex]t\leq -11[/tex]

Therefore, it tells us that in order for the helium sample to freeze in 25 minutes, the change in temperature per minute must be less than or equal to -11C.

Im not 100% sure its correct, its hard without an image or a picture of the problem

Step-by-step explanation:

Answer:

77.

Step-by-step explanation:

an = a1 + (n-1)d    where d is the common difference.

a12 = a1 + 11d

22 = a1 +11(-5)

22 = a1 - 55

a1 = 22 + 55

a1 = 77.

The first term of the arithmetic series can be obtained using the relation, A12 = a1 + 11d ; Hence, the first term is 77

To obtain the nth term of an arithmetic series ; use the relation :

The 12th term can be defined as :

22 = a1 + 11(-5)

22 = a1 - 55

22 + 55 = a1

a1 = 77

Therefore, the first term of the arithmetic series is 77

Step-by-step explanation:

Answer:

Step-by-step explanation:

so first you have to subtract 64 dollars from your balance so $98-$64=$34.

Next you have to subtract $10.85 from your new balance so it would be $34-$10.85=$23.15

Last you have to divide 23.15 by 1.65 because you have to see how many cookies you can afford, so it would be 23.15 divided by 1.65 and the answer is 14. so you can afford 14 cookies

Answer:

The best value for money is the perfume that has a 100 ml bottle because the price per ml is lower.

Step-by-step explanation:

To find which one is the best value for money, you need to find the price per ml in each case by dividing the price by the amount of ml:

-80 ml: 55/80=0.687

-100 ml: 67.50/100=0.675

According to this, the answer is that the best value for money is the 100 ml bottle because the price per ml is lower with £0.675 per ml and the 80 ml bottle has a price of £0.687 per ml.

The solution to the quadratic equation is x = negative two-thirds, negative four-fifths. Option C

From the information given, we have that;

15 x squared + 22 x = negative 8

This is represented mathematically as;

15x² + 22x = -8

Equate the quadratic expression to zero, we get;

15x² + 22x + 8 = 0

Find the pair factors of the product of 15 and 8 that sum up to 22. The value is 120

Now, substitute the value into the formula

15x² + 12x + 10x + 8 = 0

Evaluate the equation in pairs, we have;

(15x² + 12x) + (10x + 8) = 0

Factor the common terms

3x(5x + 4) + 2( 5x + 4)= 0

Then, we have;

(3x + 2) (5x + 4) = 0

If 3x + 2 = 0

x = -2/3

If 5x + 4 = 0

x = -4/5

Hence, the values are -2/3 and -4/5
