Answers
Answer:
the first one is 57
the second one is 60
3rd one is 13
4th one is 9
Step-by-step explanation:
hope this helps :) have a nice day !!
**please let me know if this was wrong**
Answer:
1) In the second step, it was supposed to multiply 9 and 2 and 36 by 3 instead of adding 9 and 3 to each other because multiplication and division comes before adding, according to pemdas.
2) In the second step, they were supposed to multiply 6 and 4 instead of subtracting 27 and 6 because multiplication comes before subtraction, according to pemdas.
3)
(43 - 20) - 2 · 5
43 - 20 = 23
23 - 2 · 5
2 · 5 = 10
23 - 10 =
13
4) 81 ÷ (13 - 4)
13 - 4 = 9
81 ÷ 9
81 ÷ 9 =
9
5) 7 · 8 - 3 · 6 + 1
7 · 8 = 56
3 · 6 = 18
56 - 18 + 1
56 - 18 = 38
38 + 1 =
39
6)
7)
8)
Step-by-step explanation:
Section 1: Explain the error in each problem below.1) Pemdas says multiplication and division comes before adding, so you must solve the multiplication in the problem first before the addition.
2) Again, as pemdas says, multiplication comes first before subtraction, so you must solve the multiplication in the problem first before the sutraction.
Section 2: Simplify the following expressions.3) (43 - 20) - 2 · 5
Pemdas says to solve the parenthesis first.
43 - 20 = 2323 - 2 · 5Now multiplication comes next (because there's no exponents).
2 · 5 = 1023 - 10Now subtraction.
23 - 10 = 134) 81 ÷ (13 - 4)
Pemdas says to solve the parenthesis first.
13 - 4 = 981 ÷ 9Now division comes next.
81 ÷ 9 = 95) 7 · 8 - 3 · 6 + 1
Pemdas says to solve the multiplication first.
7 · 8 = 56 3 · 6 = 1856 - 18 + 1Now subtraction and addition.
56 - 18 = 3838 + 1 = 396)
Section 3: Insert grouping symbols to make the statements true.7)

1. The height of a missile t seconds after it has been fired is given by h=4.9t^2+44.1t. How many seconds will it take for the rocket to reach its greatest height?
Answers
Answer:
The rocket will take 4.5 seconds to reach its maximum height.
Step-by-step explanation:
The height of a missile t seconds after it has been fired is given by h=-4.9*t²+44.1*t
This function is a quadratic function of the form f (x) = a*x² + b*x + c. In this case a=-4.9, b=44.1 and c=0
To calculate how many seconds it will take for the rocket to reach its maximum height, I must calculate the maximum of the function. The maximum of a quadratic function is the vertex of the parabola. The x coordinate of the vertex will be simply: [tex]x=\frac{-b}{2*a}[/tex]. The y coordinate of the vertex corresponds to the function evaluated at that point.
In this case the x coordinate of the vertex corresponds to the t coordinate. In other words, by calculating the x coordinate of the vertex, you are calculating the maximum time t it will take for the rocket to reach its maximum height. So:
[tex]t=\frac{44.1}{2*(-4.9)}[/tex]
t=4.5
The rocket will take 4.5 seconds to reach its maximum height.
Please help me solve this.

Answers
Answer:
Right isosceles triangle
Step-by-step explanation:
I took the quiz and got it wrong, but it told me the correct answer
A right isosceles triangle has exactly 2 equal sides and one right angle.
Given that, a triangle has exactly 2 equal sides and one right angle.
Isosceles triangle: An isosceles triangle is a triangle that has two sides of equal length.
Right isosceles triangle: An isosceles right triangle is defined as a right-angled triangle with an equal base and height which are also known as the legs of the triangle.
Obtuse isosceles: An isosceles obtuse triangle is a triangle in which one of the three angles is obtuse (lies between 90° and 180°), and the other two acute angles are equal in measurement.
Right triangle: A right triangle is a triangle in which one angle is 90°.
Hence, right isosceles triangle has exactly 2 equal sides and one right angle.

Jason has 1/3 of a liter of milk. Jason divides the milk equally into 4 mugs of tea.
How much milk will Jason have in each mug?
Answers
Answer:
1/12 l
Step-by-step explanation:
Amount of milk = 1/ 3 l
No: of mugs = 4
Amount in each mug = 1/3 ÷ 4 = 1/3 x 1/4 = 1/12 l
(Hope its right!)
Answer:
They will have 1/12 of a liter of milk on each mug because you are dividing 1/3 into 4 so the denominator is multiplied by 4

Write the equation of the line that goes through (9,-4) and is perpendicular to the line
y = -3x – 8
Answers
Answer: y = (1/3)*x - 7
Step-by-step explanation:
When we have a line:
y = a*x + b
A perpendicular line to this one needs to have a slope s equal to:
s = -(1/a)
Then any line written as:
y = -(1/a)*x + c
is perpendicular to the lines of the form "y = a*x + b"
Then if we have the line:
y = -3*x - 8
The family of perpendicular lines to this one is:
y = -(1/-3)*x + c
y = (1/3)*x + c
where c can be any real number.
Now we also want that this line passes through the point (9, -4)
Then we need to replace x by 9, and y by -4
-4 = (1/3)*9 + c
Now we can solve this for c.
-4 = 9/3 + c
-4 = 3 + c
-4 - 3 = c
-7 = c
Then the line that is perpendicular to the line y = -3x – 8 and that goes through (9, -4) is:
y = (1/3)*x - 7

The perimeter of this shape is 40cm
Calculate the value of x
Answers
Answer:
x = 8
Step-by-step explanation:
The perimeter (P) is calculated as
P = 2(l + b) ← l is length and b is breadth
Here l = 12 and b = x , P = 40, then
2(12 + x) = 40 ( divide both sides by 2 )
12 + x = 20 ( subtract 12 from both sides )
x = 8
