A recipe for cookie dough calls for three and two third cups of flour. Jane only ha 1 and three fourth cups of flour. How many m

Blizzard [7]

Answer: Jane needs 1 11/ 12 cups of flour more to make the cookie dough

Step-by-step explanation:

Recipe for cookie dough= 3 2/3cups of flour

Amount of flour available for Jane = 1 3/4 cups of flour

Amount of flour Jane needs to add to make cookie dough

=3 2/3 - 1 3/4

changing to improper fraction to make it easier to subtract

11/3 -7/4 = (44- 21)/12 = 23/12 = 1 11/12 cups of flour

Classify the real number. (Choose all that apply). –9 A.) Rational B.) Whole C.) Irrational D.) Natural E.) Integer

IRISSAK [1]

Whole numbers are the numbers 0, 1, 2, 3, 4 and so on and negative numbers are not considered whole numbers.

natural numbers are called the counting numbers that are the numbers 1, 2, 3, 4, and so on. they are positive numbers and zero is not considered a natural number as you can see.

integers are all the whole numbers and their opposite (negative) but negative numbers are NOT whole or natural numbers. fractions and decimals are not integers.

rational numbers are numbers that include all the integers, plus all fractions, or terminating decimals and repeating decimals.

irrational numbers are an infinite number of digits to the right of the decimal point, without repeating.

so your answer is integer and rational, hope this helped! :)

The points (2, r) and (6, -4) lie on a line with slope 4. Find the missing coordinate r<br> R=

Rus_ich [418]

$\text{The slope-intercept form:}\ y=mx+b\\\\\text{We have:}\ m=4\\\\\text{then}\ y=4x+b\\\\\text{The line passes through point (6; -4). Substitute:}\\\\(6;-4)\to x=6;\ y=-4\\\\-4=4\cdot6+b\\-4=24+b\ \ \ |-24\\b=-28\\\\\text{therefore:}\ y=4x-28$
$\text{substitute}\ (2;\ r)\to x=2;\ y=r\\\\r=4\cdot2-28=8-28=-20$

Answer: r = -20
