If we need to have 3/4 cup of milk for a whole recipe
For half of it, we will multiply 3/4 by 1/2 to get the result.

3/4 x 1/2 = 3/8

To make half the recipe, we need only 3/8 of a cup of milk.
The information 1 cup of pancake mix is irrelevant because the question asks only about how much milk is needed.

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

Answer:

2.25 cm³

Step-by-step explanation:

The volume of a pyramid can be found using the formula:

$\boxed{\text{volume of pyramid= ⅓×base ×height}}$

Base area

= area of square

= side ×side

= 1.5²

= 2.25 cm²

Volume of paperweight

= ⅓(2.25)(3)

= 2.25 cm³

The following data shows the number of music shows 20 students of a class watched in a month:

3241004551 [841]

Answer:

The 2nd one.

Step-by-step explanation:

First, put the numbers in order from least to greatest. This isn't required, but it makes it easier.

3 4 4 4 4 4 4 4 7 7 8 9 10 10 13 13 19 19 19 20

Then, for each range of shows watched (0-5, 6-11, etc.) from the graph, count how many numbers from the list fit into that range.

Use the process of elimination:

In 3 4 4 4 4 4 4 4 7 7 8 9 10 10 13 13 19 19 19 20, numbers from 0-5 show up 8 times, so you can rule out the last 2 graphs. Numbers 12-17 show up 2 times, so the first one is incorrect. That leaves you with the second histogram.

A garrison of 120 people had provisions for 30 days. If 20 people leave the garrison after 10 days, how long does the remaining

stiv31 [10]

Answer:

24 days

total units = 120* 30 = 3600

used after 10 days = 120*10 = 1200

remaining units after 10 days = 3600-1200 = 2400

2400/100 people = 24 days that the provisions will last
