I had $13 my mom gave $10 my dad gave $30 my aunt and uncle gave me $100 I had another $7 how much did I have
Answer:
you would have $160
Step-by-step explanation:
13+10+30+100+7= 160
The total amount $160 he have.
Given that,
He had amount already = $13
His mom gave him = $10
His dad give him = $30
His aunt and uncle give him = $100
He had another amount = $7
We have to determine,
How much amount he have..
According to the question,
To obtain the amount he had add all the amounts.
Therefore,
Total amount he had = He had amount already + Her mom gave him + His dad gave him + His aunt and uncle give him + He had another amount.
Total amount he had = $13+ $10+ $30+ $100 + $7
Total amount he had = $160
Hence, The required amount he had is $160.

plz answer only if correct.. i tried this problem many times and i keep getting the same answer..
Answer:
39
____________________________________________
Step-by-step explanation:
Since you want to find the variable x all you have to do is simple subtraction.
The two numbers (61 and 22). Subtract those numbers and you get 39. Now it wants you to round to the jearest hundredth but there is no hundreds place so we can round to the nearest tenth. Which would be 30! Hope it helped... :)!

A. A cylinder just fits into a cube of side length 36 m Calculate the percentage
of empty space in the box.
Answer:
21.5%
Step-by-step explanation:
volume of cube: 36x36x36
volume of cylinder: πx18²x36
Cylinder percentage: (πx18²x36) / 36x36x36 = π / 4 = 0.785
percentage of empty space: 1 - 0.785 = 0.215 (21.5%)
how do i get full marks? Have to write is sept by step that's what I did but only got 2 marks.
Answer:
x = 5 cm
Area = 56 cm²
Step-by-step explanation:
The perimeter of the triangle is given as : 21 cm
The two sides given are : 6 cm and 10 cm. The other side has a length of ;
21 - {6+10} = 21 - 16 = 5 cm
This means the value of x is 5 cm
The rectangle will now have its measurements as ;
Length = 7 cm
Width = x + 3 = 5+3 = 8 cm
The area of the rectangle will be :
A = l * w = 7 * 8 = 56 cm
What is the volume?

Find the gradient of the line segment between the points (-4,2) and (4,5).
Give your answer in its simplest form.
Answer:
slope= (5-2)/ 4--4

y=3/8x+c
5=3/8(4)+c
5=3/2+c
5-3/2=c
3.5=c
y= 3/8x +3.5
Step-by-step explanation:
The gradient of the line segment between the points (-4, 2) and (4, 5) is 3/8.
What is Gradient of a Line?Gradient of a line is actually the slope of the line.
Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.
Slope can also be defined as the tangent of the angle that the line is making with the positive X axis.
Gradient of a line when two points (x, y) and (x', y') are given is,
Gradient, m = (y' - y) / (x' - x)
Here, given are two points (-4, 2) and (4, 5).
x = -4, y = 2, x' = 4 and y' = 5
Gradient = (5 - 2) / (4 - -4) = 3/8
Hence the gradient of the line segment between the given points is 3/8.

A train traveled for 1.5 hours to the first station, stopped for 30 minutes, then traveled for 4 hours to the final station where it stopped for 1 hour. The total distance traveled is a function of time.
Which graph most accurately represents this scenario? (4 points)
A graph is shown with the x-axis labeled Time (in hours) and the y-axis labeled Total distance (in miles). The line begins at the origin and moves upward for 1.5 hours. The line then continues upward at a slow rate until 2 hours. From 2 to 6 hours, the line continues quickly upward. From 6 to 7 hours, it moves downward until it touches the x-axis
A graph is shown with the axis labeled Time (in hours) and the y axis labeled Total distance (in miles). A line is shown beginning at the origin. The line moves upward until 1.5 hours, then is a horizontal line until 2 hours. The line moves quickly upward again until 6 hours, and then is horizontal until 7 hours

What is the measurement of angle A?
Answer:
∠A = tan⁻¹ (35/12) ≅ 71.075 ° or 1.24 radians
Step-by-step explanation:
Since this is a right angled triangle, then we can use basic trigonometry to solve for ∠A.
We have the measure of the side opposite (35) and adjacent (12) to ∠A.
Since tan(x) = opp/adj
then tan (∠A) = 35/12
∴ ∠A = tan⁻¹ (35/12) [by taking the tan⁻¹ of both sides of the eq]
∠A ≅ 71.075 ° or 1.24 radians

Answer:
y= -x/2-1
Step-by-step explanation:
The equation of the line in the slope-intercept form is y=2x−5
The slope of the perpendicular line is negative inverse: m=−1/2
So, the equation of the perpendicular line is y=−x/2+a
To find a, we use the fact that the line should pass through the given point: −4=(−1/2)⋅(6)+a
Thus, a=−1
Therefore, the equation of the line is y=−x/2−1
Answer: y=−x/2−1
