Answer:

Frida

Step-by-step explanation:

y = 1000(2)^x

Mrs. Smith is saying that the number of termites will double each week, and Mr. Smith is saying that the number of termites will increase by 100% each week.

Let's just look at (2)^x. If we substitute numbers for x, we get:

x = 1 ⇒ 2
x = 2 ⇒ 4
x = 3 ⇒ 8
x = 4 ⇒ 16
x = 5 ⇒ 32
x = 6 ⇒ 64
x = 7 ⇒ 128

We can see that the output number doubles by 2, or in other words, increases by 100% of its value.

Therefore, Frida is correct in thinking that both Mr. and Mrs. Smith's interpretations are correct.

The answer to this question is the letter "A" which is $20.70. The solution is shown below:

If the guy will solely use the car, his expenses for the gasoline per month is:
Guy alone = $ 2.76/gallon * 15 gallons = $ 41.4

If the guy will let his two officemates ride the car and contribute each quarter of the of a tank:
First officemate = 15/4 * $2.76 = $ 10.35
Second officemate = 15/4 * $2.76 = $10.35

The guy total savings is shown below:
Total savings = $41.4 - $10.35 -$10.35
Total savings = $20.70

The answer is the letter "A".

The base of a triangular prism is an isosceles right triangle with a hypotenuse of

Setler [38]

SA= Lateral Area + Area (of base)

Lateral area = perimeter of base x height

An isosceles triangle has two congruent base segments. The hypotenuse of an isosceles right triangle is (length of base segment) x (the square root of 2). I did the math for you (shown above) to get 5 as a base.

So 5 + 5 + square root of 50 is your perimeter

Multiply the perimeter times your height (8) and you get the lateral area.

Add your lateral area to the base area (triangle = 1/2 bh)

LA = 136.568...
Area of Triangle base = 12.5

Surface area = 149.068... square cm

When I double my number add 4 and then subtract my number and subtract three I get my number plus one what is my number?

Lady bird [3.3K]

2 because once you double it, it becomes 4. Once you add 4, you get 8. When you subtract your number, which is 2, you get 6. Then when you subtract 3, you get 3. 3 is your number (2) plus 1

Answer:

There are 104.5 centiliters of paint in the mixture.

Step-by-step explanation:

Since you have a total of .50 liters of paint you would just look at the measurement and split it in half which would give you 100 centiliters and then you would add the 4.5 centiliters to the 100 and you would get 104.5 centiliters of paint.
