a recipe for cookies requires two-thirds of a cup of butter. rama wants to make 3/4 of the recipe. how many cups of of butter should she use to make cookies.
Answer:
[tex] \frac{1}{2} \: cups[/tex]
Step-by-step explanation:
Butter required for one recipe of cookies
[tex]= \frac{2}{3} [/tex] cup
Therefore,
Butter required for [tex] \frac{3}{4} [/tex] recipe of cookies
[tex]= \frac{3}{4} \times \frac{2}{3}\\\\
= \frac{1}{2} \times \frac{1}{1}\\\\
= \frac{1}{2} \: cups[/tex]

#8. Solve: 4x - 5 + 2x = 7
x = 12
x= 1/3
x = 6
x=2
Answer:
x = 2
Step-by-step explanation:
4x - 5 + 2x = 7
6x - 5 = 7
6x -5 + 5 = 7 + 5
6x = 12
6x / 6 = 12 / 6
x = 2

The diameter, [tex]D[/tex], of a sphere is 9.2 mm. Calculate the sphere's volume, [tex]V[/tex]. Use the value 3.14 for [tex]\pi[/tex], and round your answer to the nearest tenth. (Do not round any intermediate computations.)
Answer:
88.6
Step-by-step explanation:
A=4(pi)r^2/3
D=9.2 : r=4.6
A=4(3.14)(4.6^2)/3=88.5898667
4(x + 3) = -8x solve this ?
Answer:
x = -1
Step-by-step explanation:
Step 1: Write equation
4(x + 3) = -8x
Step 2: Solve for x
Distribute 4: 4x + 12 = -8x
Add 8x on both sides: 12x + 12 = 0
Subtract 12 on both sides: 12x = -12
Divide both sides by 12: x = -1
Step 3: Check
Plug in x to verify if it's a solution.
4(-1 + 3) = -8(-1)
4(2) = 8
8 = 8

Find the distance between the points with coordinates (-9,8) and (3,6). Round your answer to the nearest tenth.
Answer:
The answer is
12.2 unitsStep-by-step explanation:
The distance between two points can be found by using the formula
[tex]d = \sqrt{ ({x_1 - x_2})^{2} + ({y_1 - y_2})^{2} } \\[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(-9,8) and (3,6)
The distance between them is
[tex]d = \sqrt{ ({ - 9 -3 })^{2} + ({8 - 6})^{2} } \\ = \sqrt{ ({ - 12})^{2} + {2}^{2} } \\ = \sqrt{144 + 4} \\ = \sqrt{148} \: \: \: \: \: \: \: \: \\ = 2 \sqrt{37} \: \: \: \: \: \: \: \: \\ = 12.1655...[/tex]
We have the final answer as

Write a two-column proof. Given: line BD bisects angle CBE. Prove: angle ABD approximately equal to angle FBD.
Answer:
The proof is derived from the summarily following equations;
∠FBE + ∠EBD = ∠CBA + ∠CBD
∠FBE + ∠EBD = ∠FBD
∠CBA + ∠CBD = ∠ABD
Therefore;
∠ABD ≅ ∠FBD
Step-by-step explanation:
The two column proof is given as follows;
Statement [tex]{}[/tex] Reason
[tex]\underset{BD}{\rightarrow}[/tex] bisects ∠CBE [tex]{}[/tex] Given
Therefore;
∠EBD ≅ ∠CBD [tex]{}[/tex] Definition of angle bisector
∠FBE ≅ ∠CBA [tex]{}[/tex] Vertically opposite angles are congruent
Therefore, we have;
∠FBE + ∠EBD = ∠CBA + ∠CBD [tex]{}[/tex] Transitive property
∠FBE + ∠EBD = ∠FBD [tex]{}[/tex] Angle addition postulate
∠CBA + ∠CBD = ∠ABD [tex]{}[/tex] Angle addition postulate
Therefore;
∠ABD ≅ ∠FBD [tex]{}[/tex] Transitive property.
the area of a rectangle 54 cm2. and its length =9cm. find :
A) tge widtg of the rectangle.
B) the ratio between the width of the rectangle and its length.
C) the ratio beetween the width of the rectangle and its perimeter.
Answer:
A) 6cm
B) 2:3
C) 1:5
Step-by-step explanation:
A) area of rectangle = width × length
54cm^2 = x × 9
x = 54 ÷ 9
width = 6cm
B) the width = 6cm
the length = 9cm
the ratio between the width and the length
=》6cm : 9cm
if you simplify, it becomes 2: 3
C) the perimeter of the rectangle
= (2 × width) + (2 × length)
= (2 × 6) + (2 × 9)
= 12 + 18
= 30 cm
the ratio between the width and the perimetet
=》 6cm : 30 cm
if you simplify, it becomes 1 : 5

Question 2
Austin needs a total of $350 to buy a new bicycle. He has $35 saved. He earns $15 each week delivering
newspapers. How many weeks will Austin have to deliver papers to have enough money to buy the bicycle?
Answer:
21 weeks
Step-by-step explanation:
Equation: y = 15x + 35
15 is the rate of change and 35 is the starting point
Lets replace y with 350 since that the goal
350 = 15x + 35
Subtract 35 from both sides;
315 = 15x
Divide both sides by 15;
x = 21
He will have to deliver papers for 21 weeks to have enough money to buy a new bicycle.

find f(11)
f(11) =
F(11) means to replace x in the equation with 11
12(11) + 5
12 x 11 = 132
