Tell which set or sets the number below belongs to: natural numbers, whole numbers, integers, rational numbers, irrational numbers, or real numbers. 0
Answer:
if what you're asking if 0 belongs to anyone of the sets then zero belongs to whole numbers.
whole numbers is 0,1,2,3,4 etc
Natural numbers are 1,2,3,4 etc
integers are -3,-2,-1,0,1,2,3 etc
rational numbers are like fractions etc
irrational numbers are when you don't necessarily get a exact or whole numbers for example like π/pie
3 Ramón makes nectar for a hummingbird feeder by mixing 8 cups of water with 2 cups of sugar. Tiffany makes nectar by mixing 9 cups of water with 3 cups of sugar. Whose nectar is more sugary? Explain.
Answer:
Tiffany's nectar is more sugary
Step-by-step explanation:
Given
Ramon:
[tex]Water = 8\ cups[/tex]
[tex]Sugar = 2\ cups[/tex]
Tiffany
[tex]Water = 9\ cups[/tex]
[tex]Sugar = 3\ cups[/tex]
Required
The nectar with more sugar
To do this, we simply calculate the fraction of sugar in both nectar.
This is calculated as:
[tex]Fraction = \frac{Sugar}{Sugar + Water}[/tex]
For Ramon:
[tex]Fraction = \frac{2}{8 + 2}[/tex]
[tex]Fraction = \frac{2}{10} = 0.20[/tex]
For Tiffany
[tex]Fraction = \frac{3}{3 + 9}[/tex]
[tex]Fraction = \frac{3}{12} = 0.25[/tex]
From the calculations above:
[tex]0.25 > 0.20[/tex]
Hence: Tiffany's nectar is more sugary
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

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].

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
Marco’s bank statement says that he has an ending balance of $81. What is Marco’s starting balance?
Answer:
$255
Step-by-step explanation:
Using the information provided, in order to find Marco's starting balance we simply need to add all of his transaction costs together. Once we have this value we simply add it to his ending balance amount which will give us the total dollar value of his starting balance.
20 + 22 + 13 + 39 + 34 + 15 + 31 = 174
174 + 81 = $255
Finally, we can see that Marco's starting balance was a total of $255
Answer:
A

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.
There are values of tso that sin t= .6 and cost=.8
A. True
B. False
The correct answer to the given postulate as required in the task content is; Choice A; True.
Which is correct about the given postulate?It follows from the task content that it is required to verify if there are values of t such that; sin t= .6 and cost=.8.
Recall from square trigonometric identities that;
sin² x + cos² x = 1.
To verify if sin t= .6 and cost=.8 satisfy the given condition;
sin² t + cos² t = 1;
i.e (.6)² + (.8)² = 1
.36 + .64 = 1.
1 = 1; True.
Ultimately, the statement that t can take values such that sin t= .6 and cost=.8 is True.

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
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}
Solve using law of sines, find the area of wxy.
Answer:
area = 828.27 cm²
Step-by-step explanation:
add a line from X, perpendicular to WY, call this point A.
angle Y = 180 - 33 - 121 = 26 degrees
sin 26 = XA/49
0.4384 = XA/49
XA = 21.48 which is the height of the triangle
cos 26 = YA/49
0.8988 = YA/49
YA = 44.04
tan 33 = 21.48/WA
0.6494 = 21.48/WA
WA = 33.08
YW = 77.12
(YW)(XA)(0.5) = area
(77.12)(21.48)(0.5) = area = 828.27 cm²

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
