Amy ran 8 miles. She recorded how long it took her to run each mile, rounded to the nearest 1/4 of a minute. How long did it take Amy to run her slowest and fastest mile combined?

Answer:

-2

Step-by-step explanation:

5-(1-5÷(-5)(5+1))

Work the parentheses from the inside out

5-(1-5÷(-5)*6)

Them the Work inside the last parentheses and multiply and divide from left to right

5-(1-5÷(-5)*6)

5 divided by -5 = -1

5-(1-(-1))*6)

-1 * 6 = -6

5-(1- -6)

Then subtract

1 - -6 = 1+6 = 7

5 - (7)

Subtract

-2

Answer: To find the perimeter of a shape, we need to add the value of all of the sides. Here, we are given the values:

6cm

20cm

26cm

30cm

36cm

42 cm

All of these added together are equal to 160, so the perimeter of the shape is 160cm.

Answer:

perimeter = 160 cm

Step-by-step explanation:

perimeter = add all sides

perimeter = 6 + 20 + 26 + 30 + 36 + 42

perimeter = 160 cm

Answer:

f(x)=x^2+8x+24

Step-by-step explanation:

The reason that it is the 4th one is because there is an x^2 which indicates a quadratic and it is negative because the quadratic is going down

Answer:

5 months

Step-by-step explanation:

Jason's original weight = 120 pounds

Let the no. of months be m

If he gains 10 pounds in each moth , then his weight in m months will be = 10m

His total weight will be= 120+10m  -----(1)

Gerardo's original weight = 150 pounds

If he gains 4 pounds in each month , then his weight in m months will me =4m

His total weight will be = 150+4m-----(2)

Equating (1) ans(2)

120+10m=150+4m

=>10m-4m=150-120

=>6m=30

=>m=[tex]\frac{30}{6}[/tex]

=>m=5

It will take 5 months for Jason to weigh the same as Gerardo

Answer:

Either of the following square values:

[tex]8^{2} =64 \,\,in^2\\15^2= 225\,\,in^2\\17^2=280\,\,in^2[/tex]

Step-by-step explanation:

The three possible answers correspond to the square of the sides of the triangles via the Pythagorean theorem. And these are:

[tex]8^{2} =64 \,\,in^2\\15^2= 225\,\,in^2\\17^2=280\,\,in^2[/tex]

Answer:

3x^3+4x^2-6x

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Answer:

7 , 8 , 9

Step-by-step explanation:

Assume three consecutive number are,

x , (x+1) , (x+2)

Multiplied by 2 ,3 and 4 respectively

2x , 3(x + 1) , 4(x + 2)

Sum of all = 74

So,

2x + 3(x + 1) + 4(x + 2) = 74

2x + 3x + 3 + 4x + 8 = 74

9x + 11 = 74

9x = 63

x = 7

So,

x , (x+1) , (x+2)

7 , (7+1) , (7+2)

7 , 8 , 9

Answer:

Step-by-step explanation:

7.6 is greater

Problem 1

To convert from gallons to cups, we multiply by 16 since 1 gallon = 16 cups

Therefore, 4 gallons = 64 cups

==================================================

Problem 3

1 hour = 60 minutes

4 hours = 240 minutes (multiply both sides by 4)

==================================================

Problem 5

100 cm = 1 meter

1 cm = 0.01 meter (divide both sides by 100)

53 cm = 0.53 meter (multiply both sides by 53)

==================================================

Problem 6

1 foot = 12 inches

3 feet = 36 inches (multiply both sides by 3)

1 yard = 3 feet

1 yard = 36 inches

2 yards = 72 inches (multiply both sides by 2)

Answer: 120

Step-by-step explanation:

Given : Total toppings = 6

Number of toppings needs to be selected = 3

Also if repetition of toppings is not allowed , then the number of combinations are possible = 6 x 5 x 4   [First we choose 1 out of 6 , then 1 out of remaining 5 and then 1 out of 4,then multiplying the choices for 3 toppings]

=  120

Hence, the number of different pizza topping combinations are possible if the maximum number of allowed toppings is 3 is 120 .

Answer:

A. 0.25 B. 625/1000 C. 0.875

Answer: D: 3.

Step-by-step explanation:

Ok, vamos a contar los dígitos de derecha a izquierda.

El dígito que ocupa el lugar de la centena de millón va a ser el 9. (o el primero contando de izquierda a derecha).

en el numero 341,427,538 el noveno dígito es un 3.

Entonces el numero que esta en el lugar de la centena de millón es un 3

La opción correcta es D

Answer:

Option (C)

Step-by-step explanation:

x and y are two rational numbers.

Two inequalities which define these numbers are,

x + y < 5 ------(1)

3 < x < 5 -------(2)

In this question we will substitute the values of y given in the options in the inequality (1) to get the value of x. If the value of x satisfies the inequality (2), it will be the answer.

Option (A). y = [tex]\frac{8}{3}[/tex]

From inequality (1),

[tex]x+\frac{8}{3}<5[/tex]

[tex]x<5-\frac{8}{3}[/tex]

x < [tex]\frac{7}{3}[/tex]

x < 2.33

But 3 < x < 5, therefore, y = [tex]\frac{8}{3}[/tex] is not the answer.

Option (B). y = 2

x + 2 < 5

x < 3

But x is greater than 3. Therefore, Option (B) will not be the answer.

Option (C). y = 0

x + 0 < 5

x < 5

Inequality (2) states the same thing.

Therefore, Option (C) will be the answer.

Option (D). y = 3

x + 3 < 5

x < 5 - 3

x < 2

But x > 3, therefore, Option (D) will not be the answer.

Answer:

C is correct because if x is less than 5 and greater than 3 than is would most likely be 4 and 4 plus 0 equals 4 the problem says x plus y should be less than 5 and 4 plus 0 is less than 5

Answer:

-6/7p + 1/7

Step-by-step explanation:

Like Terms: terms that have the same variables and powers

In this equation the like terms are -4/7p and -2/7p

First solve that, which will be -6/7p + 1/7

You have to leave the 1/7 alone because there aren't any more numbers with no variables.

Answer:

Step-by-step explanation:

You can only combine terms that are the same, which means you can only combine the fractions with p attached. A + and - make a -. The second fraction changes to negative or subtraction which ever way you want to say it.  -4 - 2 = -6 and the bottom number always stays the same  and you keep the letter attached. You can not combine 1/7 because it does not have a p attached. You would leave it the same. [tex]\frac{-6}{7}p +\frac{1}{7}[/tex]

Answer:

the answer is tan 20 =0.364

Step-by-step explanation:

we can write sin(3x+10)= cos{90-(3x+10)}

now

cosx= cos{90-(3x+10)}

eliminating cos from both sides we get

x=90-3x-10

4x=80

x=20

tan 20=0.364

it can be 40 also

if we take the sin part

Answer:

Hey there!

Your answer is close- but not quite! You chose y=10x, however, if you look closely, the cost is 10 at 2 sandwiches. Thus, the slope should be 5, and correct answer would be y=5x.

Answer:

Measure of the third outgoing current will be 0.34 ampere.

Step-by-step explanation:

Kirchhoff's Current Law states that total current entering a circuit's junction is exactly equal to the total current leaving the same junction.

By this rule,

Sum of input three currents = Sum of three outgoing currents

0.38 + 0.75 + 0.29 = 0.48 + 0.6 + i

1.42 = 1.08 + i

i = 0.34

Therefore, measure of the third outgoing current will be 0.34 ampere.

Answer:

2 2/3 or 24/9

Step-by-step explanation:

3 2/9 - 5/9 = 24/9 = 2 6/9

3*9+2 = 29/9

29/9 - 5/9 = 2 6/9

2 6/9 turns into 2 2/3

2 2/3 is equal to 24/9

Answer:

2 2/3

Step-by-step explanation:

What you do is make 3 2/9 into an improper fractions --> 9 * 3 + 2 = 29/9

29/9 - 5/9 = 24/9

So, now you're going to make 24/9 into a mixed number which is 2 6/9 --> 2 2/3

Answer:

The first term is a = 0.4.

Step-by-step explanation:

We are given the indicated terms of an arithmetic sequence; [tex]a_3[/tex] = 1, [tex]a_3_3[/tex] = 22.

As we know that the nth term of the A.P. is given by;

[tex]a_n=a+(n-1)d[/tex]

where, a = first term and d = common difference

Now, the third term of AP is given as 1, this means;

[tex]a_3=a+(3-1)d[/tex]

[tex]a+2d=1[/tex]

a = 1 - 2d  --------------- [equation 1}

Also, the 33rd term of AP is given as 22, this means;

[tex]a_3_3=a+(33-1)d[/tex]

[tex]a+32d=22[/tex]

[tex]1-2d+32d=22[/tex]     {using equation 1}

[tex]30d=21[/tex]

[tex]d=\frac{21}{30}[/tex]

d = 0.7

Putting the value of d in equation 1 we get;

[tex]a=1-(2 \times 0.7)[/tex]

a = 1 - 1.4 = -0.4

Hence, the first term of an AP is -0.4.

Answer:

Y°= 115

D = (3,1)

Step-by-step explanation:

For y, your just looking through the vertex. essentially if its 115 on one side it's going to be the same on the other because it all has to be equal, and that's how vertex's work.

for D. Read the instructions and make a square

x goes first then y

Answer:

-15 + 8i

Step-by-step explanation:

(1 + 4i)²

(1 + 4i) (1 + 4i)

FOIL - first -- outer -- inner -- last

F -- 1 x 1 = 1

O -- 1 x 4i = 4i

I -- 4i x 1 = 4i

L -- 4i x 4i = 16i²

combine terms

1 + 4i + 4i + 16i²

simplify

1 + 8i + 16i²

(i² = -1)

simplify further

1 + 8i + (16)(-1)

1 + 8i - 16

-15 + 8i
