How many cookies are lemon cookies?

Answer:

$ 2330

Step-by-step explanation:

a = $240

Earning at the end of fifth week = $ 680

increase in earnings per weak = ( 680 -240)/2     = 440/2 =110

d =110

l = a + (n-1)d

a20 = 240 + (19 * 110 ) = 240 + 2090 =   2330

10+x=14; x=4

10+x=14

-10     -10

The 10's cancel out

x=4

Answer:  10+x=14

Step-by-step explanation:

The word "sum" implies addition, so we know we are going to be adding some values. The next part of the sentence just give you your two values, 10 and a number (x). We know to add these two together because of the word sum. The final part of the sentence is "is equal to 14" this simply mean =14. Put all the pieces together and you get : 10+x=14

Answer:

4.2×10to the 6th or 4,200,000

Step-by-step explanation:

First you have to know that you are multiplying these two numbers. When you multiply exponents like there you add the matissa's (6&7) and add the exponents.

6×10to the 2 * 7×10to the 3rd

42 × 10to the 2+3

42×10to the 5th

Something else you need to know is your matissa cant be higher than 10

So:

4.2 × 10to the 6th is your answer

The sample contains 42 × 10⁵ red blood cells.

When same base is multiplied their powers gets added.

For example - a×a×a×a×a×a = a⁶.Here a has nothing in it's power means it has 1 to it's power.

According to the given question

For every 1 while blood cells an average person has 6x10² times as many red blood cells.

A small sample of blood contains 7 × 10³ white blood cells.

∴ The amount of red blood cells in the sample is

= (7 × 10³)(6× 10²) red blood cells.

= (7×6)(10³×10²)

= 42 × 10⁵ red blood cells.

Answer:

Equation of the line is y=-x+3

Rewritten as an inequality is y ≤ -x+3

Step-by-step explanation:

You find the slope by doing rise over run which ends up being -1/1, so just -1.

The y-intercept is 3.

Slope intercept form is y=mx+b, so y=-x+3 is the answer in slope intercept.

Then ≤ is used because the line is going down and it's shaded to the left, also the line isn't broken, it's solid which means it's equal to, so it would be less than or equal to.

Explanation in the picture.

Answer:

Step-by-step explanation:

The answer is 1-4/5

Estimate the product of 3,182 multiplied by 5 by rounding to the nearest hundred, resulting in an estimation of 16,000.

To estimate the product of 3,182 multiplied by 5, we can round 3,182 to the nearest hundred to make the multiplication simpler.

Rounding 3,182 to the nearest hundred gives us 3,200.

We then multiply 3,200 by 5:

3,200 x 5 = 16,000

This estimated product is not an exact answer but gives us a reasonable approximation that is easy to calculate mentally or on paper.

Answer:

2. [tex]f(x)=\frac{x^2}{x+5}[/tex]

Step-by-step explanation:

When you replace x=5 into those functions you obtain:

[tex]1. f(x)=\sqrt{x^2-36} = \sqrt{5^2-36} = \sqrt{-11} \\2. f(x)=\frac{x^2}{x+5}=\frac{5^2}{5+5}=\frac{25}{10}[/tex]

We can see that the function number 1, when the x=5 is replaced, falls into the imaginary numbers or complex domain, so the function is not continuous in the real domain.

On the other hand, the second function falls into the real domain whe x=5 is replaced, so the function is continuous in the real domain!

After solving the given mathematical expression which is $5.40 + $8.70 + $6.30 , we get value equal to $20.40

What is addition ?

The process of adding two or more numbers together or combining things into one group is known as addition.

The given arithmetic expression is $5.40+$8.70+$6.30.

Let's solve the given mathematical expression.

To add decimal numbers , place the decimal point in line with the specified decimal points, align the decimal numbers in accordance with their place values. If we look at the given decimals, we can see that they are like decimals because they have two digits after the decimal point. Therefore, we will arrange them in the proper sequence and perform standard addition rule.

i.e.,

5.40 + 8.70 + 6.30

We can write this as sum of :

= (5+8+6) + (0.40 + 0.70 + 0.30)

Now , solving to get the value :

= (19) + (1.40)

= $20.40

Therefore, after solving the given mathematical expression which is $5.40 + $8.70 + $6.30 , we get value equal to $20.40

To get -18, we can use the factors

To find two numbers that multiply to give -18, we need to consider pairs of factors of -18. The factors of -18 are:

1 and -18

2 and -9

3 and -6

So, the pairs of numbers that multiply to give -18 are:

1 * -18 = -18

2 * -9 = -18

3 * -6 = -18

Therefore, -18 can be expressed as the product of various combinations of these pairs, such as (-2) * 9, (-3) * 6, and so on.

OC) 4.527 x 10^3

Step-by-step explanation:

To write a number in scientific notation, first move the decimal point to create a number between 1 and 10.

4527. becomes 4.527

To get your exponent, count how many places you moved the decimal. In this case, you moved the decimal three places.

4.527 * 10^3

Answer:

14 miles.

Step-by-step explanation:

Let the distance traveled from home to destination = x miles.

Speed while going to friend's house = 35 miles per hour.

Speed while coming back = 40 miles per hour.

Total Time taken for the journey = 45 minutes = 0.75 hours.

Let the time taken while going to friend's house = y hours.

Therefore, the time taken while going to friend's house = (0.75 - y) hours.

To find x and y, model the speeds of both the journeys.

Speed while going to friend's house = Distance/Time.

35 = x/y.

x = 35y (Equation 1).

Speed while coming back = Distance/Time.

40 = x/(0.75 - y).

x = 40(0.75 - y) (Equation 2).

Since x = x, therefore:

35y = 30 - 40y.

75y = 30.

y = 30/75.

y = 0.4 hours.

Put y = 0.4 hours in Equation 1:

x = 35y.

x = 35(0.4).

x = 14.

Therefore, the distance between my friend's house and my house is 14 miles!!!

Answer:

The distance from my house to friend's house is 14 miles

Step-by-step explanation:

* Lets explain how to solve the problem

- Driving to the friend's house rate is 35 miles per hour

- Driving to my home rate is 40 miles per hour

- The round trip took 45 minutes

- We need to find the distance from my house to my friend's house

* At first lets change 45 minutes to hour because the rate of driving

 unit is miles per hour

∵ 1 hour = 60 minutes

∴ 45 minutes = [tex]\frac{45}{60}=\frac{3}{4}[/tex] hour

- Assume that the distance from my house to friend's house is d,

 the time for the trip from my house to the friend's house is [tex]t_{1}[/tex]

 and the time from friend's house to my house is [tex]t_{2}[/tex]

∵ The distance between the two houses is d

∵ Distance = rate of driving × time of the trip

∴ d = 35 × [tex]t_{1}[/tex] = [tex]35t_{1}[/tex]

∴ d = 40 × [tex]t_{2}[/tex] = [tex]40t_{2}[/tex]

- Equate the two equations

∴ [tex]35t_{1}[/tex] = [tex]40t_{2}[/tex]

- Divide both sides by 35

∴ [tex]t_{1}=\frac{40}{35}t_{2}=\frac{8}{7}t_{2}[/tex]

∴ [tex]t_{1}=\frac{3}{4}t_{2}[/tex] ⇒ (1)

- The time of the round trip is [tex]\frac{3}{4}[/tex] hour

∴ [tex]t_{1}+t_{2}=\frac{3}{4}[/tex] ⇒ (2)

- Substitute equation (1) in equation (2)

∴ [tex]\frac{8}{7}t_{2}+t_{2}=\frac{3}{4}[/tex]

∴ [tex]\frac{15}{7}t_{2}=\frac{3}{4}[/tex]

- Divide Both sides by [tex]\frac{15}{7}[/tex]

∴ [tex]t_{2}=0.35[/tex] hour

∵ d =  [tex]40t_{2}[/tex]

- Substitute the value of [tex]t_{2}[/tex] in the equation above

∴ d = 40(0.35) = 14

∵ d represents the distance from my house to friend's house

∴ The distance from my house to friend's house is 14 miles

Answer:(-0.3,3.25)

Step-by-step explanation:

The midpoint of P(-2,2.5) and Q(1.4,4) is ( -0.3, 2.25)

A midpoint is defined as in the middle of the line connecting two points a position known as a midpoint. A location in the middle of a line connecting the two points that are equally far from both points is the midpoint.

Let two points A (x₁, y₁) and B (x₂, y₂), the midpoint between A and B is given by,

M(x, y) = (x₁ + x₂)/2, (y₁ + y₂)/2

Given P(-2,2.5)  and Q(1.4,4)

So the midpoint = [(-2 + 1.4)/2, (2.5 + 4)/2]

The midpoint =  [(-0.6)/2, (4.5)/2]

The midpoint = ( -0.3, 2.25)

Hence, the midpoint of P(-2,2.5) and Q(1.4,4) is ( -0.3, 2.25).
