What is the meaning of the point with an x-coordinate of 2?
Answer:
A
Step-by-step explanation:
Because the x-coordinate is in seconds. Which eliminates answer B
Also, the Y-coordinate is measured in 40 meters per unit, this eliminates C and D.
Please help Lia brought 21 shirts and plants. Her total was $357. Pants cost $25 each, and shirts cost $14.50 each. How many of each item did she buy? Show your work

pants
52.5÷ 25 = 2.1
Which quadratic function in vertex form has a vertex at (−5 , −4) and passes through the point (−2 , −1)?
y=−13(x+5)^2−4
y=−13(x−5)^2+4
y=13(x−5)^2−4
y=13(x+5)^2−4
Answer:
y = 1/3(x + 5)^2 - 4
Step-by-step explanation:
The general vertex form is;
y = a(x-h)^2 + k
From the question, (h,k) are the coordinates of the vertex which is (-5,-4)
So we have
y = a(x + 5)^2 -4
So we need to get the leading coefficient
Simply substitute the point it passes through
x = -2 and y = -1
-1 = a(-2 + 5)^2 - 4
-1 = a(3)^2 -4
-1 = 9a -4
9a = 4-1
9a = 3
a = 3/9
a = 1/3
So the equation is;
y = 1/3(x + 5)^2 - 4

The total surface area of a cube is 294cm^2.
Work out the volume of the cube.
Answer:
343 cm ^3
Step-by-step explanation:
A cube has 6 squares of equal sizes. 294/6 = 49
The area of one square is 49
Since the area is the length squared, the square root of 49 is 7.
Volume of a cube is area times height. 49 x 7 = 343 cm^3

Allen wants to have a mean of 90 on his math quizzes. So far, he has scored 86, 94, 88, 95, and 89. What is the least score that Allen needs on his next quiz to have a mean of 90?
Answer:
88
Step-by-step explanation:
[tex] \frac{86 + 94 + 88 + 95 + 89 + x}{6} = 90[/tex]
The mean would be the sum of all the math quiz grades divided by the number of quizzes taken.
Solve for x:
[tex]86 + 94 + 88 + 95 + 89 + x = 540[/tex]
[tex]452 + x = 540[/tex]
[tex]x = 88[/tex]
Thus, Allen needs at least an 88 to obtain a mean of at least 90.

how do I get the answer to 2/5 times 3
Answer:
6/5
Step-by-step explanation:
2/5*3=2/5*3/1=6/5
Answer:
[tex]\frac{6}{5}[/tex] or [tex]1\frac{1}{5}[/tex]
Step-by-step explanation:
[tex]\frac{2}{5} *3[/tex]
3 can be rewritten as 3/1
[tex]=\frac{2}{5}*\frac{3}{1}[/tex]
Multiply the numerators and denominators
[tex]2*3=6\\5*1=5[/tex]
[tex]= \frac{6}{5}[/tex]
You can also change this into a mixed number by dividing the numerator by the denominator and writing the remainder as the numerator:
[tex]= 1\frac{1}{5}[/tex]

Answer:
[tex]\frac{x-1}{x+2}[/tex]
Step-by-step explanation:
simplifying the equation: [tex]x^2-3x+2/x^2-1[/tex]
1) Rewrite the equation so it's easier to understand:
[tex]\frac{x^2-3x+2}{x^2-4}[/tex]
2) factor [tex]x^2-3x+2[/tex]:
[tex]x^2-3x+2[/tex] [tex]=> (x-1)(x-2)[/tex]
3) factor [tex]x^2-4[/tex]:
[tex]x^2-4 => (x+2)(x-2)[/tex]
Meaning: [tex]\frac{(x-1)(x-2)}{(x+2)(x-2)}[/tex]
4) Cancel the common factor: [tex](x-2)[/tex] from the numerator and the denominator:
[tex]=\frac{x-1}{x+2}[/tex]

Norma had 3/8 birthday cake left over from her party . She ate 3/4 of the leftover cake at lunch. How much of the whole cake did Norma have at lunch?
Answer:
1/ 2
Step-by-step explanation:
Given that :
Fraction left over = 3/8
Fraction of leftover ate = 3/4
Amount of the whole cake Norma have at lunch :
Fraction left over ÷ fraction of left over ate
3/8 ÷ 3/4
3/8 * 4/3
(3*4) / (8*3)
12 / 24
1/2
1/2 of the whole cake
Answer:
1/2!!

Answer:
a = [tex]\frac{12}{\sqrt{3} }[/tex]
Step-by-step explanation:
Using the tangent ratio in the right triangle and the exact value
tan30° = [tex]\frac{1}{\sqrt{3} }[/tex] , then
tan30° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{a}{12}[/tex] = [tex]\frac{1}{\sqrt{3} }[/tex] ( cross- multiply )
a × [tex]\sqrt{3}[/tex] = 12 ( divide both sides by [tex]\sqrt{3}[/tex] )
a = [tex]\frac{12}{\sqrt{3} }[/tex]
