Let #N mean the number of days in year N. What is the value of #1988 + #1989 + #1990 + #1991?

A) 1460
B) 1461
C) 1462
D) 1463

Answer:

the point on the plane (-15, 5)

Step-by-step explanation:

These lines are:

1)  a vertical line (x=-15) which implies that all x values of the points that it contains have coordinate x= -15

2) a horizontal line (y=5) which implies that all y values of the points that it contains have coordinate y = 5

Then the intersection must occur at x = -15 and y = 5, that is at the point (-15, 5)

Answer:

805

Step-by-step explanation:

Scaling up by a factor of ten means that you must multiply the original number by 10. Because 10 has one zero, the best way to figure this out is just moving the decimal to the right ONCE (just like there is ONE zero)! This gives us 805.

Answer:

Part 1: Already solved.

Part 2: 1 quesadilla.

Step-by-step explanation:

Part 1: The data points given are 0, 0, 1/4, 1/2, 1/2, 1, 1, 1, 5/4, 2, and 2.

The data are already sorted from least to greatest.

Part 2: To get the interquartile range, we must know the first and third quartiles. To find those, we need to know the median of the data.

There are 11 data points, so we can cross out 5 numbers on the left and cross out 5 numbers on the right. That leaves a median of 1.

Since we know the median is 1, we can find the first quartile by finding the median of the following numbers: 0, 0, 1/4, 1/2, 1/2 (any number less than 1). There are five numbers, so cross out two numbers from the left and cross out two numbers from the right. We are left with a first quartile of 1/4.

Now that we have the first quartile, we need to find the third quartile. Since the median was actually the first "1" in the data set, the third quartile will be the median of the numbers to the right of that "1": 1, 1, 5/4, 2, 2. Cross out the leftmost two numbers, and cross out the rightmost two numbers. We are left with a third quartile of 5/4.

Now that we have both the third and first quartiles, we can find the interquartile range! The IQR is calculated by finding the third quartile minus the first quartile. 5/4 - 1/4 = 4/4 = 1.

So, your interquartile range is 1 quesadilla.

Answer:

$118

Step-by-step explanation:

The amount Jordan will have on 1st of the February is $118

The slope or gradient of a line is a number that describes both the direction and the steepness of the line.

Given that, On February 2nd, Jordan is going on a class trip to Washington, D.C. He is saving his weekly allowance to use as spending money while on the trip. Each week, Jordan's parents give him the $8 he earned for the week,

The saving are

In 1st week = $86

In 2nd week = $94

Therefore, we can consider the coordinates as (1, 86) or (2, 94)

We know that, standard equation of a line = y = mx+c

Where, m is the slope,

We have here slope = 8

Finding for c, put x = 1 and y = 86

c = 78

Now finding the amount for 5 weeks, that means x = 5

y = 5x8+78

y = 118

Hence, The amount Jordan will have on 1st of the February is $118

Answer:

7i.

Step-by-step explanation:

Note : The given expression must be [tex]\sqrt{-49}[/tex].

We have to write this radical value in the imaginary value.

The given value can be rewritten as

Answer: 10.

Step-by-step explanation:

You are given the equation

(ax+b)(ax+c)=4x^2-25

Expand the Left hand side by opening the bracket.

a^2x^2 + axc + abx + bc

a^2x^2 + (axc + abx) + bc = 4x^2 + 0x - 25

From the equation above, we can see that;

a^2x^2 = 4x^2

a^2 = 4

a =  √4

a = 2

Also, axc + abx = 0x

axc = abx

ax will cancel out from both sides

c = b

From the equation, bc = 25

But c = b. Substitute c for b

b^2 = 25

b =  √25

b = 5 = c

b + c is therefore 5 + 5 = 10

Answer:

x= 3/2 = 1.5

Step-by-step explanation:

● 5(4x-10)+10x =4(2x-3)+2(x-4)

Simplify the products

● 5*4x-5*10+10x = 4*2x-4*3+2*x-2*4

● 20x-50+10x = 8x-12+2x-8

Add the terms that don't contain x with each other

●20x-50+10x = 8x-20+2x

Add 20 in both sides

●20x-50+20+10x = 8x-20+2x+20

●20x-30+10x = 8x+2x

Add together the terms that contain x

●30x -30 = 10x

Add -10x in both sides

●30x-30-10x = 10x-10x

● 20x -30 = 0

Add 30 in both sides

● 20x-30+30 = 30

● 20x = 30

Divide both sides by 20

●20x/20 = 30/20

● x= 30/20

● x= 3/2

● x= 1.5

Answer:

Option A. √(x + 1)

Step-by-step explanation:

Data obtained from the question include:

f(x) = √(x² – 1)

g(x) = √(x – 1)

(f/g) (x) =..?

(x² – 1) => difference of two square

(x² – 1) => (x – 1)(x + 1)

f(x) = √(x² – 1)

f(x) = √(x – 1)(x + 1)

(f/g) (x) = f(x) /g(x)

f(x) = √(x – 1)(x + 1)

g(x) = √(x – 1)

(f/g) (x) = √(x – 1)(x + 1) / √(x – 1)

(f/g) (x) = √[(x – 1)(x + 1) / (x – 1)]

(f/g) (x) = √(x + 1)

Answer:

13, 15, 17

Step-by-step explanation:

Each digit must be odd, and to get consecutive odd integers, you must add using the multiple of 2:

Let the least number be "x". Set the equation:

(x) + (x + 2) + (x + 4) = 45

Isolate the variable, x. First, combine like terms:

(x + x + x) + (2 + 4) = 45

(3x) + 6 = 45

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 6 from both sides:

3x + 6 (-6) = 45 (-6)

3x = 45 - 6

3x = 39

Divide 3 from both sides:

(3x)/3 = (39)/3

x = 39/3

x = 13

Your first number (x) is 13. Solve for the other 2 numbers:

(x) = 13

(x + 2) = 13 + 2 = 15

(x + 4) = 13 + 4 = 17

13, 15, 17 are your numbers:

Check:

13 + 15 + 17 = (13 + 15) + 17 = 28 + 17 = 45
