Answer:
The grapefruit is 20% heavier than the apple
Step-by-step explanation:
Say the orange's weight is o.
Grapefruit = 1.08o
Apple = 0.9o
So to find the percentage the grapefruit is bigger, you have to first do 1.08 - 0.9 = 0.18
0.18 / 0.9 = 0.2
0.2 = 20%
Answer:
i'm pretty sure the grapefruit is 20% more
Sorry if i'm wrong
Have an amazing day :)
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?
(Hint: Halving an amount is the same as
dividing the amount by 2)
cups of flour
Answer:
3 cups
Step-by-step explanation:
the original recipe calls for 6 cups of flour (3 times as much as sugar. sugar is 2 cups, times 3 is 6)
half it: 6/2 = 3
Answer:
3 cups of flour.
Step-by-step explanation:
If sugar is 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.

3 1/2 - 4 2/5
how do i do this?
Answer:
Ok so first you would have to turn them into improper fractions which is
3 [tex]\frac{1}{2\\}[/tex] = [tex]\frac{7}{2}[/tex] and 4 [tex]\frac{2}{5}[/tex] = [tex]\frac{22}{5}[/tex]
So now that you have made them both improper fractions you have to find common denominators.
To find common denominators you must multiply both the numerator and the denominator by the same thing. Since your oposing fraction has a denominator of 5 you can know that a even number wont go in an odd number so take [tex]\frac{22}{5}[/tex] and mutiply both numbers by 2 and get [tex]\frac{44}{10}[/tex]. Then mutiply both numbers in [tex]\frac{7}{2}[/tex] by 5 to get a common denominator.
[tex]\frac{35}{10}[/tex]
[tex]\frac{35}{10} -[/tex] [tex]\frac{44}{10}[/tex] =35 - 44 = -9 so your answer is [tex]-\frac{9}{10}[/tex]

The point (-3,2) lies on a circle whose equation is (x + 3)^2 + (y + 1 )^2 =r^2. Which of the following must be the radius of the circle?
Answer:
1. 3
2. A
Step-by-step explanation:
1. (-3+3)^2 + (2 + 1)^2 - r^2 = 0
0 + 9 - r^2 = 0
r^2 = 9
r = 3
2. 2x^2 + 4x + 2y^2 + 12y = - 6
Divide by 2.
(x^2 + 2x) + (y + 6y) = -3
Remember how to complete the square..
(b/2)^2
So...
(2/2) ^ 2 = 1
(6/2) ^ 2 = 9
(x^2 + 2x + 1) + (y^2 + 6y + 9) = -3 + 1 + 9 <--- You must remember to add whatever you add on the left to the right!
Now.. rewrite in standard form..
(x+1)^2 + (y+3)^2 = 7
Careful!! the circle equation is written as
(x - h)^2 + (y - h)^2 = r^2
Meaning that the radius is square root of 7. At center (-1, -3)
fifteen darts have landed on the dart board shown. each dart scores 3,5, or 7 points. in how many different ways can the fifteen darts score a total of 75 points
Answer:
The answer is "8".
Step-by-step explanation:
Let the number are a, b, c then value is as follows:
a= 3
b= 5
c= 7
The addition of equation ⇒ a+b+c =15....................(i)
multiply by the value ⇒ 3a + 5b + 7c = 75 ...............(ii)
let b= 15-a-c which subtract from equation (ii)
equation:
⇒ 3a + 5b + 7c = 75
⇒ 3a + 5(15-a-c) + 7c = 75
⇒ 3a +75-5a-5c+7c = 75
⇒ 3a -5a-5c+7c = 75-75
⇒ -2a + 2c = 0
⇒ 2(c-a) = 0
⇒ (c-a) = 0
⇒ c=a
if we put value in between 0 to 7 from it satisfies the two equations, with c=a and b = 15 - a - c. So, the correct answer is 8.

A tree was 63 inches tall. Several years later it was 107 inches tall.
What was the percent increase, to the nearest hundredth, of the height of the tree? Enter the answer in the box.
percent
Answer:
69.84%
Step-by-step explanation:
percentage increase
[tex]\frac{107-63}{63} \times 100\\=\frac{44}{63} \times 100\\=\frac{4400}{63} \\=69.84/%[/tex]
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Required percentage value = a
total value = b
Percentage = a/b x 100
The percentage increase in the height of the tree is 69.84%.
What is a percentage?
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Height of the tree = 63 inches.
Height after several years = 107 inches.
Now,
The percentage increase in the height of the tree.
= (107 - 63)/63 x 100
= 44/63 x 100
= 69.84%
Thus,
The percentage increase in the height of the tree is 69.84%.

Drag the tiles to the boxes to form correct pairs. Not all tiles will be used.
Match each pair of points A and B to point such that _ABC = 90°.
A(3, 3) and B(12, 6)
C(6,52)
A(-10, 5) and B(12, 16)
C(16, -6)
A(-8, 3) and B(12, 8)
C(18,4)
A(12, -14) and B(-16, 21)
C(-11, 25)
A(-12, -19) and B(20, 45)
A(30, 20) and B(-20, -15)
When two lines intersect at 90° degrees angle, the lines are perpendicular to each other. Two perpendicular lines, their slope will give a product of -1
i.e. if the first's line slope is 5, then the second line's will be -1 ÷ 5 = -¹/₅
To find the slope of a line, we divide the vertical distance by the horizontal distance.
We'll use the trial and error method to find the right pairing
Let's start with A(3, 3) and B(12, 6)
Vertical distance =
Horizontal distance =
The slope AB = ³/₉ = ¹/₃
We want BC to have a slope -1 ÷ ¹/₃ = -3
Try C(16, -6); check the slope with B(12, 6)
Vertical distance =
Horizontal distance =
Slope of BC = -12 ÷ 4 = -3
The slope BC = -3 is the value we want so, tile 1 pair with tile 4
-------------------------------------------------------------------------------------------------------------
Let's do A(-10, 5) and B(12, 16)
Vertical distance = 16 - 5 = 11
Horizontal distance = 12 - -10 = 22
Slope AB = ¹¹/₂₂ = ¹/₂
The perpendicular slope would be -1 ÷ ¹/₂ = -2
Try C(18, 4) with B(12, 16)
Vertical distance = 16 - 4 = 12
Horizontal distance = 12 - 18 = -6
Slope BC = ¹²/₋₆ = -2
Slope BC and slope AB perpendicular, so tile 3 matches with tile 6
--------------------------------------------------------------------------------------------------------------
Let's try A(12, -14) and B(-16, 21)
Vertical distance = 21 - -14 = 35
Horizontal distance = -16 - 12 = -28
The slope AB = ³⁵/-₂₈ = ⁵/₋₄
We need the perpendicular slope to be -1 ÷ -⁵/₄ = ⁴/₅
Try C(-11, 25)
Vertical distance with B = 25 - 21 = 4
Horizontal distance with B = -11 - -16 = 5
The slope = ⁴/₅
Tile 7 matches tile 8
--------------------------------------------------------------------------------------------------------------
Take A(-12, -19) and B(20, 45)
Vertical distance = 45 - -19 = 64
Horizontal distance = 20 - -12 = 32
Slope AB = ⁶⁴/₃₂ = 2
We need the perpendicular slope to be -1 ÷ 2 = -¹/₂
We have C(6, 52) and checking the slope with B(20, 45)
Vertical distance = 45 - 52 = -7
Horizontal distance = 20 - 6 = 14
The slope is ⁻⁷/₁₄ = -¹/₂
Tile 9 pairs with tile 2
-----------------------------------------------------------------------------------------------------------

Tile 1 ⇒ Tile 4
Tile 3 ⇒ Tile 6
Tile 7 ⇒ Tile 8

Answer:
It will take 7 hours for car B to catch up to Car A.
Step-by-step explanation:
So if you write the the two equations out:
[tex]Car A=70x\\Car B= 90x-140[/tex]
You'll want to assume that x is how many hours and y is how many km.
The reason car B has, -140, is because car A is in front of it by two hours and in those two hours it reached 140km. Meaning that Car B is starting at 140 km behind Car A.
If you graph these two equations out you'll realize that they intersect at the point (7, 490). Meaning that Car B caught up with Car A after 7 hours and both cars had traveled 490km.
