Kelly is creating lemonade by mixing 3 parts lemon juice with 2 parts sugar. If she uses 3
cups of sugar, how many cups of lemon juice does she use?
Answer:
lemon juice : parts sugar
3 :2
? :3
3/2 × 3 = 4,5 cups of lemon
Answer:
4.5
Step-by-step explanation:
the ratio of lemon juice to parts sugar is 3:2. to convert into cups, it turns into ?:3. to turn 2 into 3, you multiply by 1.5, so you have to do the same to 3, to get 4.5, 3:2 is equal to 4.5:3 so kelly would have to use 4.5 cups of lemon juice.
A line with a slope of 3 passes through the point (2, 6). What is its equation
in slope-intercept form?
please help i need my ixl done and i don’t understand this lesson
Answer:
I found: y=−3x+12
Explanation:
You can use the relationship:
y−y0=m(x−x0)
Where m is the slope and x0,y0 the coordinates of your point.
So with your data:
y−6=−3(x−2)
y=−3x+6+6
y=−3x+12
or:
3x+y=12
Translate this phrase into an algebraic expression.
8 more than twice Matt's savings
Use the variable m to represent Matt's savings.
Answer:
2m + 8
Step-by-step explanation:
It's rather simple to break it down, take "8 more" as (+ 8) and twice Matt's savings into (2 * m) which then becomes simply (2m). Because of pemdas, your final answer should be 2m first then + 8, so 2m+8

Submit Answer
Answer:
attempt 1 out of
O
Answer:
The value of [tex]f\,\circ\,g(-8)[/tex] is 16.
Step-by-step explanation:
The composition consist: in replacing the independent variable ([tex]x[/tex]) of [tex]f(x)[/tex] by [tex]g(x)[/tex]:
[tex]f(x) = x^{2}-3\cdot x -12[/tex] (1)
[tex]g(x) = -x-12[/tex] (2)
[tex]f\,\circ\,g (x) = (-x-12)^{2} - 3\cdot (-x-12) -12[/tex] (3)
[tex]f\,\circ\,g(x) = (x^{2}+24\cdot x + 144) +(3\cdot x +36) - 12[/tex]
[tex]f\,\circ\,g(x) = x^{2} +27\cdot x +168[/tex]
[tex]f\,\circ g(-8) = (-8)^{2}+27\cdot (-8) +168[/tex]
[tex]f\,\circ\,g(-8) = 16[/tex]
The value of [tex]f\,\circ\,g(-8)[/tex] is 16.

Q. Mohammed calculated the volume of the prism as 240 cm3. Is he correct? *
a- yes
b- no
Answer:
I gues s it s yes. if correct brainlest answer pla..
Answer:
No
Step-by-step explanation:
The formula for a triangular prism is
[tex] \frac{1}{2} a \times h[/tex]
where a is the area of the triangle.
The area of a triangle is
[tex] \frac{4 \times 5}{2} = 10[/tex]
so the volume is
[tex]10 \times 12 = 120[/tex]
what are the x intercepts if y is 16x takeaway 8x squared?
Answer:
The x-intercepts are (0, 0) and (2, 0)
Step-by-step explanation:
The function is y = 16x - 8x^2.
To find the x-intercepts, we set this function equal to zero (0) and solve the resulting equation for x:
16x - 8x^2 = 8x(2 - x) = 0.
Then 8x = 0 yields x = 0 and 2 - x = 0 yields x = 2
The x-intercepts are (0, 0) and (2, 0)

Determine whether the triangles are congruent. Explain your reasoning .
SAS (Side, Angle, Side) or ASA (Angle, Side, Angle)
Answer:
The triangles are congruent by congruency theorem SAS.
Step-by-step explanation:
Side-Angle-Side, as it suggests, is when a triangle is congruent by the order of congruent side, congruent angle, and another congruent side. If named certain ways, they can be congruent. Since the question does not provide a specific way of naming the triangles, we can assume that any way is allowed. 2.5 and 2.5 are congruent, followed by angles D and G which have the congruent angle markers. The congruent angles are followed by 1.7 and 1.7, making the triangles congruent by Side-Angle-Side.

A rectangular tank measures 30 cm by 20 cm by 40 cm. How many milliliters of water are in the tank when it is full? How many liters is that? Solve this problem in the math section
Answer:
24000 cm³ or 24 L
Step-by-step explanation:
The measure of a tank is 30 cm by 20 cm by 40 cm.
We need to find the volume of water in the tank when it is full.
Volum = 30 cm × 20 cm × 40 cm
= 24000 cm³
1 cm³ = 1 ml
24000 cm³ = 24000 mL
Also, 1 cm³ = 0.001 ml
24000 cm³ = 24 L
Hence, this is the required solution.
what is the answer to
3 + 2x = -6x + 4
Answer:
if you are looking to solve for x the answer is
[tex] \frac{1}{8}[/tex]
Step-by-step explanation:
first you need to gather all the variables (x) to one side of the equation so take right hand side:
2x + 6x = 4 - 3
remember to watch out for the sign changes. then:
[tex]8x = 1[/tex]
therefore
[tex]x = \frac{1}{8}[/tex]
someone help me out please:(
Answer:
[tex]m(x) = - 3x - 3[/tex]
Step-by-step explanation:
[tex]m(x) = f(x) - g(x)[/tex]
[tex]m(x) = (2x+1)−(5x+4)[/tex]
[tex]m(x) = 2x+1−(5x)−1 \times 4[/tex]
[tex]m(x) = 2x+1−5x−1 \times 4[/tex]
[tex]m(x) = 2x+1−5x−4[/tex]
[tex]m(x) = −3x+1−4[/tex]
[tex]m(x) = −3x−3[/tex]

Answer:
Top box: Endpoint
Bottom box: Ray
Step-by-step explanation:
Assuming that the top box is supposed to be for the point shared by both rays, then it is a endpoint of the rays, as the lines do not continue past the point on the opposite side.
The bottom box will then be a ray, as no point is shown, and a arrow is used at the "end" of the line to signify that it will continue on forever.
