Look at the two rectangles on the centimetre square grid.
B
A
a)
Which rectangle (A or B) has the larger area? a
b) Explain how you know.
Answer:
A has the larger area.
Step-by-step explanation:
You can find a rectangle's are by multiplying its width by its height.
For triangle A the width is 5, and the height is 3. 5 × 3 = 15
For triangle B the width is 6 and the height is 2. 6 × 2 = 12
15 is greater than 12, so rectangle A has a larger area than rectangle B.
The area of rectangle [1] is greater than rectangle [2].
What is a rectangle?A rectangle is a plane figure with four straight sides and four right angles, especially one with unequal adjacent sides, in contrast to a square.
Given are two rectangles.
Assume that the side of the square block is 1 unit.
Now, for rectangle [1], we can write -
A [1] = L x B = 5 x 3 = 15 units square
For rectangle [2], we can write -
A [2] = L x B = 6 x 2 = 12 units square
Now, A[1] > A[2]
Therefore, the area of rectangle [1] is greater than rectangle [2].

I REALIZED I DID IT WRONG SO UH IGNORE WHAT I SAID IM SORRY D:
Area of the triangle is 1/2 base x height
1/2(6)x(7)
21m^2
Area of the rectangle is l x b

Total area = area of triangle + area of reactangle
Total area = 21m^2 + 60m^2

Answer:
C
Step-by-step explanation:
The area of cylinder is the area of the base (pi r^2) and the height (5)
Answer:
C
Step-by-step explanation:
Well if you think about it the normal formula is V=πr^2h
A cylinders base is a circle and the area for a circle is πr^2
If you cancel πr^2 you are left with height
So therefore it would be V=area of the base*height
3. What three numbers are the Pythagorean triple generated by using 4 for x and 1 for y. Remember to use the formulas:
a = x2 - y2, 6 - 2xy, and C = x2 + y2
O 6, 8, and 10
O 5, 11, and 12
O 8, 15, and 17
O 3, 5, and 8
Given:
The three equations for the three numbers are
[tex]a=x^2-y^2[/tex]
[tex]b=2xy[/tex]
[tex]c=x^2+y^2[/tex]
To find:
The Pythagorean triple generated by using 4 for x and 1 for y.
Solution:
Substituting x=4 and and y=1 in the given equations, we get
[tex]a=4^2-1^2[/tex]
[tex]a=16-1[/tex]
[tex]a=15[/tex]
In the same way find b and c.
[tex]b=2(4)(1)[/tex]
[tex]b=8[/tex]
The third number is
[tex]c=4^2+1^2[/tex]
[tex]c=16+1[/tex]
[tex]c=17[/tex]
The required Pythagorean triple is 8, 15, and 17.
Therefore, the correct option is C.
What type of angles are ∠4 and∠6?
Question 2 options:
adjacent angles
alternate exterior angles
alternate interior angles
corresponding angles
none of these
Answer:
None of these
Step-by-step explanation:
For adjacent, they are not next to each other.
For alternate exterior, both are not exterior.
For alternate interior, both are not interior.
For corresponding, they are not along the same line.
That leaves us with the answer none of these.

Find the value of X. WILL GIVE BRAINLIEST
Answer:
X = 12
Step-by-step explanation:
the total degree of any triangle is 180.
therefore I took (7x + 4) + (5x + 3) + ( 2x + 5) = 180
I replace the Xs with 12 and then the answer is 180
(7(12) + 4) + (5(12) + 3) + ( 2(12) + 5) = 180
The figure below shows a shed in the shape of a rectangular prism.
Note that the shed has a floor.
Answer:
Step-by-step explanation:
a). Volume of a rectangular prism = Length × width × height
= 13 × 8 × 12
= 1248 cubic ft
Surface area of a rectangular prism = (lb + bh + hl)
Here, l = length, b = width and h = height of the rectangular prism
Surface area of the given prism = (13×8 + 8×12 + 12×13)
= 356 square ft
b). If the shed is made of metal,
Metal needed to make the shed = Volume
c). The shed is used for the storage.
Measure would be used → Surface area

How many distinct positive integer-valued solutions exist to the equation (x2 - 7x + 11)(x2 - 13x + 42) = 1
Answer:
The given equation has TWO positive integer valued solutions, {6, 7}
Step-by-step explanation:
Here we are given two trinomial factors, each of which needs to be set equal to zero and in each case the resulting quadratic equation solved.
(x^2 - 7x + 11) has the coefficients {1, -7, 11}, and so the discriminant of this quadratic is b^2 - 4(a)(c), or 49 - 4(11), or 5.
Because this discriminant is positive, we know immediately that this quadratic has two real, unequal roots involving √5 (NO integer roots).
Next we focus on (x^2 - 13x + 42). The discriminant is b^2 - 4(a)(c), or
169 - 168, or 1. Again we see that there are two real, unequal roots:
+13 ± √1 +13 ± 1
x = --------------- or x = -------------
2 2
OR x = 14/2 = 7 (integer) or x = 12/2 = 6 (integer).
The given equation has TWO positive integer valued solutions, {6, 7}

Bags of sugar come in 3 sizes:
Small bag: A 250 g bag costs 95p.
Medium bag: A 500 g bag costs £1.80.
Large bag: A 3 kg bag costs £3.70.
Calculate the cost of 3 kg for the small and medium bags.
Give your answer in pounds to 2 dp.
Write the bag that is the better value in the comments
Answer:
Medium
Step-by-step explanation:
The computation is shown below:
The cost for the small and medium bag is shown below:
As we know that
1kg = 1000g
So 3kg = 3000g
Now for small bags
= 0.95 ÷ 250 × 3000
= £11.40
For medium bags
= £1.80 ÷ 500 × 3000
= £10.80
So here the medium bag would represent the better value

A word problem that represents division equation '16 divided by 2 =8' is Dayana and his friend John bought a 12lb bag of candy at the grocery store. If they want to share it equally, how much candy will each person get?
What is division?The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.
We have expression:
16 divided by 2 =8
In numerator form,
16 ÷ 2 = 8
Dayana and his friend John bought a 12lb bag of candy at the grocery store.
If they want to share it equally, how much candy will each person get?
16 ÷ 2
16 / 2 = 8
16 divided by 2 =8
The quotient is 8.
It means that each person will get 8lb of candy.

determine the measure of angles A and B
Answer:
Angle A is 52 degrees Angle B is 78 degrees
Step-by-step explanation:
The angles all have to add up to 180.
2x + 3x + 50 = 180
5x + 50 = 180
Subtract 50 from both sides
5x = 130
Divide each side by 5
x = 26
Solve
A) 2 * 26 = 52
B) 3 * 26 = 78
--------Check--------
52 + 78 +50 = 180
180 = 180

A flower is constructed by 44 workers in 99 days.if 121 workers are employed to do the job.how many days will it take to complete the construction.
9514 1404 393
Answer:
36
Step-by-step explanation:
We assume that time is inversely proportional to the number of workers. So increasing the number of workers by a factor of 121/99 = 11/9 will decrease the number of days by a factor of 9/11.
(9/11)(44 days) = 36 days
It will take 36 days to complete the construction with 121 workers.
