Answer:
2.65 gallons
Step-by-step explanation:
He originally had 4 gallons and he used 1.05 gallons.
4 - 1.05 = 2.95
He then used another three-tenths to take another friend home.
Three-tenths is equal to 3/10 or 30/100 or 0.30
2.95 - 0.30 = 2.65 gallons

Answer:
4x^3 (3)_/x + 10x^3 (3)_/x
Step-by-step explanation:
First lets solve the first term
When you multiply exponents you add them, so x^10 can be split into:
x^3 * x^3 * x^3 * x^1
We can then take it out.
4x^3 (3)_/x
Then for the other part we can also factor it.
2*2*2 is 8 so we can take that out and multiply it by 5 =10
You can keep x in there since you can factor it into smaller pieces.
The final answer you get when you add all of it together is :
4x^3 (3)_/x + 10x^3 (3)_/x

Arika and Savroop have 19 ½ cups of flour. They want to make loaves of banana

cups of flour. Savroop has a recipe that calls for 1 ½ cups of flour. Select all the
statements that are true about the recipes.
O Arika's recipe will make 10 whole loaves of banana bread.
O Savroop's recipe will make 14 whole loaves of banana bread.
O There will be less flour leftover if Savroop's recipe is used.
( There will be less flour leftover if Arika's recipe is used.
D More loaves of bread can be made using Arika's recipe than using Savroop's recipe.
Statements A and C are correct.
Here, we are given that Arika and Savroop have 19 ½ cups of flour. Arika had a recipe for banana bread that calls for 1 ⅞ cups of flour. Savroop has a recipe that calls for 1 ½ cups of flour.
Let us evaluate each option one by one-
A. Arika's recipe will make 10 whole loaves of banana bread.
Arika's recipe requires 1 ⅞ cups of flour = (8 + 7)/8
= 15/8
Total flour they have = 19 ½ = (19 × 2 + 1)/2
= 39/2
Thus, Arika's recipe will make = 39/2 ÷ 15/8
= 39/2 × 8/15
= 13 × 4/ 5
= 52/5
= 10.4
Thus, the given statement is correct.
B. Savroop's recipe requires 1 ½ cups of flour = (2+ 1)/2
= 3/2
Thus, Savroop's recipe will make = 39/2 ÷ 3/2
= 39/2 × 2/3
= 13
Thus, the given statement is incorrect. Savroop's recipe will make only 13 whole loaves.
C. As we can see above, Arika's recipe will make 10.4 loaves and thus 0.4 cups of flour will be left over. Whereas, in case of Savroop, no flour will be left over. Thus, the given statement is true.
D. By the same reasoning given above, the given statement is false as there will be less flour leftover if Savroop's recipe is used.
E. The given statement is again false as Arika's recipe will make only 10 loaves whereas Savroop's recipe will make 13.

How to determine the volume of the Washington Monument
In this problem we must determine the volume of a obelisc, which is equal to the sum of the volumes of a square frustrum and a pyramid with a square base. First, sum the volumes of the frustrum and the pyramid:
V' = (1 / 3) · 500 · (55² + 55 · 34.5 + 34.5²)
V' = 1018791.667 ft³
V'' = (1 / 3) · (34.5)² · 55.5
V'' = 22019.625 ft³
Second, calculate the volume of the obelisc:
V = V' + V''

Is Figure B a scale copy of figure A?
Yes, figure B is a scale copy of figure A.
As per the question statement and its reference diagram attached thereby, we are provided with two geometrical figures of same shape but different sizes.
We are required to determine if figure B is a scale copy of figure A or not.
To solve this question, we need to carefully compare the lengths of the corresponding sides from both the figures.
We can clearly see that, the dimension of every side of figure B is twice that of the corresponding side of Figure A, i.e.,
[tex](1*2)=2\\(2*2)=4\\(3*2)=6\\(4*2)=8[/tex]
Hence, it is proved that figure B is a scale copy of figure A.
Scale copy: In geometry, a scale copy of a figure is another figure having same shape, but the dimensions of all the sides of the scale copy are equal multiples of the dimensions of the corresponding sides of the original figure.To learn more about Scale Copy, click on the link below.

The area of the parallelogram is 4 times the area of the triangle.
The perpendicular height of the parallelogram is h cm.
Find the value of h.
*HOMEWORK QUESTION*
Answer:
13
Step-by-step explanation:
Area of triangle = 0.5 × base × height
= 0.5 × 6 × 13
= 39
Area of parallelogram = 4 × Area of triangle
Note - Area of parallelogram = base × perpendicular height
Hence,
Base × perpendicular height = 4 × 39
12 × H = 156
H = 156 ÷ 12
= 13
Answer = 13
Answer:
h = 13 cm
Step-by-step explanation:
the area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
here b = 6 and h = 13 , then
A = [tex]\frac{1}{2}[/tex] × 6 × 13 = 3 × 13 = 39 cm²
Then the area (A) of the parallelogram = 4 × 39 = 156 cm²
the area (A) of the parallelogram is calculated as
A = bh ( b is the base and h the height )
here b = 12 , then
12h = 156 ( divide both sides by 12 )
h = 13
