Answer:
2/3 of the jar was filled with flour
Step-by-step explanation:
The question is incomplete. Here is the complete question.
A jar can hold 3/4 of a pound of flour. Austin empties 1/2 of a pound of flour into the jar. What fraction of the jar is filled? Enter your answer in numerical form.
Given
Amount a jar can hold a = 3/4 of a pound of flour
If Austin empties 1/2 of a pound of flour into the jar, then the amount emptied into the jar b = 1/2 pounds
Fraction of jar filled will be expressed as b/a as shown;
b/a = (1/2)/(3/4)
b/a = 1/2 ÷ 3/4
b/a = 1/2 * 4/3
b/a = 4/6
Simplify to the lowest term
a/b = 2*2/2*3
a/b = 2/3
Hence 2/3 of the jar was filled with flour
PLEASE HELP, #30 and #40 !! DUE SOON
Answer:
38. x = 60
40. x = 10
Step-by-step explanation:
38.
The segment labeled 30 connects the midpoints of two sides of a triangle, so it is parallel and half the length of the third side.
x = 2 * 30 = 60
40.
Look at the big outer triangle.
Its left side has length x. It is made up of two segments that are congruent.
The right side of the big triangle is made up of two segments that are congruent and are also congruent to the segments of the left side. That makes the left and right sides of the big triangle congruent. This is an isosceles triangle, so its base angles are congruent. The left base angle measures 60, so the right base angle also measures 60. That means the top angle also measures 60. This triangle is isosceles and equilateral.
Since the segment measuring 5 has endpoints that are midpoints of two sides of a triangle, it is parallel to the third side and half its length.
The bottom side of the triangle measures 2 * 5 = 10. Since the triangle is equilateral, then x = 10.
A recipe for cookies calls for 1 cup of butter, twice as much sugar as butter, and three times as much flour as sugar. How many cups of flour will you need if you halve the recipe?
Answer : 3 cups
Explanation: if the sugar is as twice as much as butter we need 2 cups of sugar if flour is 3 times as much as sugar we’ll need 6 cups half of 6 is 3
if 2x + 5y = -5 what is x if y = -5
HELP ASAP
Answer:
x=10
Step-by-step explanation:
first substitute y with the value (-5)
2x+5(-5)=-5 which is simplified to 2x+-25=-5
add 25 to -5 which gives you 2x=20
then divide 20 by 2 which makes x=10
The land John owns covers an area of 2.17 x 104 square miles. The land Sam owns covers an area of 5.34 x 103 square miles. About how many times greater is the area owned by John than the area owned by Sam?
Answer:4.064 times
Step-by-step explanation:
Step 1
Area of Land owned by John =2.17 x 104 square miles
Area of Land owned by Sam= 5.34 x 103 square miles.
When we say about how many times is a quantity greeter than the other we mean that how much is the smaller quantity contained in the larger quantity. and in such cases, we divide.
Area of Land owned by John/Area of Land owned by Sam
=2.17 x 104 square miles/ 5.34 x 103 square miles
=21,700 square miles /5,340 square miles
=4.064 times
Therefore we say that John's owns an area of land by 4.064 times Sam's land.
Tommy bought stamps at the post office. Some of the stamps had a snowflake design, some had a truck design, and some had a rose design. Tommy bought 14 snowflake stamps. He bought 5 more truck stamps than snowflake stamps, and 5 fewer rose stamps than truck stamps. How many stamps did Tommy buy in all? Show your work, how you came up with the answer.
Answer:
47
Step-by-step explanation:
s = Number of stamps with snowflake design = 14
Number of stamps with truck design is 5 more than snowflake design
[tex]t=s+5\\\Rightarrow t=14+5\\\Rightarrow t=19\ \text{stamps}[/tex]
Number of stamps with rose design is 5 fewer than truck stamps
[tex]r=t-5\\\Rightarrow r=19-5\\\Rightarrow t=14\ \text{stamps}[/tex]
Total number of stamps
[tex]s+t+r=14+19+14\\ =47[/tex]
So total number of stamps Tommy bought is 47.
Let a(x) be the amount of money remaining on Hillary's gift card after purchasing x apps on her phone.
Since a(12) = (38, 15,35, 65) Hillary will have
(35,15,38,12) dollars remaining on her card after purchasing
(12,15,35,38) apps.
Answer:
she purchased 12 apps costs 12 *1.25 = 15 . So , she spent 15 ... Since a(12) = 35, Hillary will have 35 dollars remaining on her card after purchasing 12 apps.

Which function has a graph with a y-intercept of -4?
A. 2x – 4y = 8
B. 2x – 8y = -4
C. 4x – 2y = -8
D. 4x - 2y = 8
Answer:
D
slope is 2 and y-intercept is (0, -4)
Step-by-step explanation:
4x-2y= 8 move variable x to the right (change signs)
- 2y= -8 + 4x Divide both sides by 2
y= -4 + 2x reorder terms using communitive property
y = 2x -4
y= mx + b

-11
Answer:
x = -11
Step-by-step explanation:
Well the two equations add up to 180 because they are a linear pair.
x + 56 + x + 146 = 180 (collect like terms)
2x + 202 = 180 (subtract 202 on both sides)
2x = -22 (divide by 2 on both sides)
x = -11
