hey guys umm help me
yo i need help please ( if u can’t see the problem zoom in btw ) but fr i need to pass plz help
Answer:
Given no. of persons owned laptop = 76
Total of no. of students owned + Total of no. of students dont have owned laptop given = 155
No. of students dont have laptops = 155 - 76 = 79
So then the total no. of no laptops = 79 + 17 = 96(ans)

Answer:
96
Step-by-step explanation:
once you fill in the Blanks that are solvable, you will work your way into the answer. For example, the first column, the missing number has to be 155-76 or 79. Now you can find your answer. In the second row, “no Laptop”, you have 79 (solved above) plus 17. So your answer is 79+17 or 96.

Anthony's Nuffin Shop recently sold 4 blackberry muffins and 6 other muffins. Considering
this data, how many of the next 20 muffins sold would you expect to be blackberry muffins?
Answer:
8
Step-by-step explanation:
In total, Antony sold 10 muffins. We can do a ratio like this:
[tex]\frac{4}{10} = \frac{x}{20}[/tex]
Because there are 4 blackberry muffins. We solve.
Because 10 is directly half of 20, we can just multiply 4 by 2 because if you multiply 10 by 2, you'd get 20. 4 times 2 is 8. That's the answer.
The circumference of a circular painting is 43.96 feet. What is the diameter of the painting? Use 3.14 for π and do not round your answer.
Answer:
14 feet
Step-by-step explanation:
c = πd
Plug in the givens
43.96 = 3.14d
Divide both sides by 3.14
14 = d
Answer:
Diameter = circumference ÷π
43. 96÷3. 14 =14 feet

Samantha saw two bottles of ketchup at the store for the same price. One bottle contained 4 pints of ketchup, and the other contained 1.25 quarts of ketchup.
Which bottle was the better bargain?
Answer:
The 4 pint ketchup bottle was the better bargain.
Step-by-step explanation:
To find which bottle was the better bargain, find which one had the most amount of ketchup in it.
In one quart, there are 2 pints.
Convert the 1.25 quart bottle to pints by multiplying 1.25 by 2:
1.25(2)
= 2.5
Since 4 is larger than 2.5, the 4 pint bottle of ketchup has more.
So, the 4 pint ketchup bottle was the better bargain.

Pythagorean Theorem: a2 + b2 = c2
Answer:
b= the square root of 20
Step-by-step explanation:
if a^2+b^2=c^2, then c^2-a^2=b^2. 6^2-4^2=c^2. So 36-16=b^2. 36-16=20.20=b^2, then take the square root of both sides to get b= the square root of 20.

Find the area of the shaded region
Answer:
227 units²
Step-by-step explanation:
Area of rectangle
a = (2 * 11.5) * (4 * 11.5)
a = 1,058
Area of circles
a = 2(π * 11.5²)
a = 830.9512568745
Shaded area
a = 1,058 - 830.9512568745
a = 227.0487431255
a ≈ 227
What function returns a reference to a cell (or cell range) that is a specified number of row and columns from a base cell?
Answer:
The offset function
Step-by-step explanation:
In Microsoft Excel, the offset function or formula returns reference to a particular cell.
The syntax is:
= OFFSET(reference, rows, cols)
Where:
reference = the base cell
rows and cols are the direction to move
For instance:
OFFSET(A1, 3, 1) will return cell B4
Because:
3 will shift down the reference from A1 to A4
1 will shift right the reference from A4 to B4

If ABCD is dilated by a factor of 2, the
coordinate of B' would be:
B' ([?],[?])
PLEASE HELP I WILL MARK BRAINLIEST!!
Answer:
I believe its (- 2, 2 )
Step-by-step explanation:
Assuming the dilatation is centred at the origin, then multiply the coordinates of B by the scale factor 2, that is
B(- 1, 1 ) → B'(2(- 1), 2(1) ) → B'(- 2, 2 )
Find the slope of the line that passes through each pair of points.
Answer:
0.5
Step-by-step explanation:
Slope (m) =
ΔY
ΔX
=
1
2
= 0.5
θ =
arctan( ΔY ) + 180°
ΔX
= 206.56505117708°
ΔX = 0 – 2 = -2
ΔY = 0 – 1 = -1
Distance (d) = √ΔX2 + ΔY2 = √5 = 2.2360679774998
Equation of the line:
y = 0.5x
When x=0, y = 0
When y=0, x = -0

Quadrilateral WXYZ will be rotated 180° about the origin and then reflected across the Y axis. Choose all of the statements about the quadrilateral and/or the transformed quadrilateral that are correct.
Answer:
The quadrilaterals will be congruent
The quadrilateral will now appear in Quadrant 2
Step-by-step explanation:
Given
[tex]W = (-7,-2)[/tex]
[tex]X= (-4,-2)[/tex]
[tex]Z = (-6,-6)[/tex]
[tex]Y =(-3,-7)[/tex]
Rotation across 180 degrees
Reflection across y-axis
Required
The true statement
Using point W as a point of reference; We have:
[tex]W = (-7,-2)[/tex]
1. Rotation across 180 degrees
The rule is:
[tex](x,y) \to (-x,-y)[/tex]
So:
[tex]W(-7,-2) \to W'(7,2)[/tex]
2. Reflection across y-axis
The rule is:
[tex](x,y) \to (-x,y)[/tex]
So:
[tex]W'(7,2) \to (-7,2)[/tex]
Using the above transformation on the other points; We have:
[tex]W(-7,-2) \to W"(-7,2)[/tex]
[tex]X (-4,-2) \to X "(-4,2)[/tex]
[tex]Z (-6,-6) \to Z" (-6,6)[/tex]
[tex]Y(-3,-7) \to Y"(-3,7)[/tex]
Plot the above points on a grid (see attachment).
From the grid, we can conclude that: the quadrilaterals will be congruent , and it will appear in Quadrant 2.

Each envelope in the class contains the same number of triangles and quadrilaterals. Write an expression that
represents the total number of sides in the room.
Answer: 3t+4q.
Step-by-step explanation: Triangles have 3 sides, so there will be 3 sides for each triangle in the envelope. This is represented by 3t. Quadrilaterals have 4 sides, so there will be 4 sides for each quadrilateral in the envelope. This is represented by 4q. The total number of sides will be the number of triangle sides and the number of quadrilateral sides together.
