Answer:

I'm assuming you want me to do 18-23? Okay:

Step-by-step explanation:

18) 8.6(10^−4)+6.7(10^−5)

=0.000927 --> 9.27 × 10^-4

19) 3.5(10^3)−9(10^1)

=3410 --> 3.41 × 10^3

20) 5.6(10^4)(4.5(10^6))

=252000000000 --> 2.52 × 10^11

21) 7.6(10^−7)(8.9(10^−2))

=0 --> 0

22) 3.9(10^−12)/4(10^4)

=0 --> 0

23) 1.75(10^5)/5(10^−3)

=35000000 --> 3.5 × 10^7

Please comment below if you would like me to solve #24 :)

The bolded numbers are the answer, the underlined numbers are to show the question number. Hope this helped !!

Una araña comió 25%, percent más bichos este mes que el mes pasado. La araña comió 8 bichos el mes pasado

lesantik [10]

For this case we have that the complete question is:

A spider ate 25% more bugs this month than last month. The spider ate 8 bugs last month. How many bugs did the spider eat this month?

So, we propose a rule of three:

8 bugs -----------> 100%

x -----------------------> 25%

Where the variable "x" represents the number of bugs equivalent to 25%.

$x = \frac {25 * 8} {100}\\x = 2$

Thus, 2 bugs represent 25%

If this month the spider ate 25% more, then it ate:

$8 + 2 = 10$

Answer:

This month, the spider ate 10 bugs

find the number of terms in an AP given that its first and last terms are 13 and - 23 respectively and that its common differenc

Leokris [45]

Answer:

There are 17 terms in the sequence

Step-by-step explanation:

Arithmetic Sequence

An arithmetic sequence is a list of numbers with a definite pattern by which each term is calculated by adding or subtracting a constant number called common difference to the previous term. If n is the number of the term, then:

$a_n=a_1+(n-1)r$

Where an is the nth term, a1 is the first term, and r is the common difference.

In the problem at hand, we are given the first term a1=13, the last term an=-23, and the common difference r=-2 1/4. Let's solve the equation for n:

$\displaystyle n=1+\frac{a_n-a_1}{r}$

We need to express r as an improper or proper fraction:

$\displaystyle r=-2\frac{1}{4}=-2-\frac{1}{4}=-\frac{9}{4}$

Substituting:

$\displaystyle n=1+\frac{-23-13}{-\frac{9}{4}}$

$\displaystyle n=1+\frac{-36}{-\frac{9}{4}}$

$\displaystyle n=1+36*\frac{4}{9}=17$

n=17

There are 17 terms in the sequence
