Diego scored 9 points less then Andre in the basketball game.Noah scored twice as many points as Diego.if Noah scored 10 points , how many points did Andre score

Answers

Answer:

14 points.

Step-by-step explanation:

To solve this problem, let's make an equation.

Let x represent the unknown number, or the amount of points Andre scored.

We know that Noah scored 10 points.

Noah scored twice as many points as Diego, therefore Diego must've scored 5 points, because 5 * 2 = 10.

So, if Diego scored 9 points less than Andre, and we know that Diego scored 5 points, then the equation we are left with is

x - 9 = 5

To solve, just add 9 to both sides.

x - 9 + 9 = 5 + 9

We are left with:

x = 14

So, Andre scored 14 points.

The circumference of a circle is approximately 3.14 times the length of its diameter. Which inequality can be used to find all possible diameter lengths, d, if the circumference of a circle is more than 50 cm?

Answers

Answer:

3.14d > 50 cm

Step-by-step explanation:

Given that the circumference of a circle is approximately 3.14 times the length of its diameter

If the circumference is C and the length of the diameter is d then

C = 3.14d

If the circumference of a circle is more than 50 cm then

3.14d > 50

The  inequality can be used to find all possible diameter lengths, d,

d > 50/3.14

d > 15.92cm

Lin runs 8 laps around a track in 26 minutes.

How many minutes and seconds?

Answers

Answer:

3 minutes and 15 seconds per lap.

Step-by-step explanation:

26 ÷ 8 = 3.25

Multiply 3.25 times 60 to get the amount in seconds.

3.25 x 60 = 195

Then, subtract 60 from 195 until you can't subtract 60 anymore.

195 - 60 = 135

135 - 60 = 75

75 - 60 = 15

Add the number of times 60 was subtracted.

60 = 1 minute

So 1 + 1 + 1= 3 minutes.

Then, the 15 left over from 195 after 60 was subtracted from it three times is the amount of seconds.

3 minutes and 15 seconds per lap.

Dakota makes salad dressing by combining 4 1/3 fluid ounces of oil and 3 3/8 fluid ounces of vinegar in a jar. She then pours 3 1/4 fluid ounces of the dressing onto her salad. How much dressing remains in the jar?

Answers

9514 1404 393

Answer:

  4 11/24 fl oz

Step-by-step explanation:

The volume of dressing Dakota made is ...

  4 1/3 + 3 3/8 = (4 +3) +(1/3 +3/8) = 7 + (8/24 +9/24) = 7 17/24 . . . ounces

After using 3 1/4 ounces, the remaining amount is ...

  7 17/24 - 3 1/4 = (7 -3) +(17/24 -6/24) = 4 11/24 . . . . ounces

4 11/24 fluid ounces of dressing remains in the jar.

Which of the following is an arithmetic sequence with common difference –5?


8, 3, –2, –7, . . .

B)

0, 5, 10, 15, . . .

C)

5, 25, 125, 625, . . .

D)

5, –25, 125, –625, . . .

Answers

Answer:

Option A i.e. 8, 3, -2, -7, ... is correct.

Step-by-step explanation:

Let us check the sequence given in option A

[tex]8, 3, -2, -7, . . .[/tex]

An arithmetic sequence has a constant difference '[tex]d[/tex]' and is defined by  

[tex]a_n=a_1+\left(n-1\right)d[/tex]

determine the differences of all the adjacent terms of Arithmetic sequence

[tex]3-8=-5,\:\quad \:-2-3=-5,\:\quad \:-7-\left(-2\right)=-5[/tex]

The difference between all the adjacent terms is the same and equal to

[tex]d=-5[/tex]

Therefore, we conclude that the arithmetic sequence 8, 3, -2, -7, ... has a common difference -5.

Hence, option A i.e. 8, 3, -2, -7, ... is correct.

Answer:

8, 3, –2, –7, . . .

Step-by-step explanation:

Determine if the sequence is arithmetic.If it is find the common difference, the 52nd term 38,47,56,65

Answers

Answer:

497

Step-by-step explanation:

Since if we take the difference between each number i.e.

47 - 38 = 9

56 - 47 = 9

65 - 56 = 9

As the difference is same that means it is a arithmetic sequence

Now

The 52nd term is

a(n) = a +(n-1)d

a(52) = 38 +  (52 - 1) (9)

a(52)= 38 + 51 (9)

= 38 + 459

= 497

Answer:

she bought 2 fancy shirts, and 5 plain shrits.

Step-by-step explanation:

$35×2=$70 (for the fancy shirts so she bought 2 fancy shirts)

Now, we have 5 shirts left that she bought so they must be plain shirts. to check, we would multiply $10×5=$50, then we would add $70(from the fancy shirts) and $50 (from the plain shirts) and get a total of $120.
