Answer:
C. 5√2
Step-by-step explanation:
The hypotenuse of an isosceles right triangle is √2 times the length of either leg. The given leg (YZ) is 5 units, so the hypotenuse XY is 5√2 units.
Which one hurry
A.9
B.18
C.27
D.33
Answer:
It’s c I do believe
Answer:
seriously, talk to your teacher. its 21 units squared.
I guess the person who draw this had 18 units squared in mind, but failed to properly draw it.
so none of the options really fit. it's just a badly done problem. not your fault though. its just some of these little things to be just a little mad about.

A box is shaped like a square prism. The box is 10 centimetres high and it’s volume is 150 cubic centimetres.
Answer:
B I hope
Step-by-step explanation:
The length of the base of a square prism is 3.872 cm and the surface area of a square prism is 184.9 cm ²
Volume of a square prismLet h is the height length of the prism and a is the length of base edge.
then the volume is a²h and the surface area is 2a²+4ah
How to base length?(a) The volume of a square prism is 150 cm³ and 10 cm is height length
Let a is the length of base edge.
We know the volume is a²h.
Substitute the values
a²(10) = 150
a² = 15
a = √15
a = 3.872 cm
Since length of base is 3.872 cm.
How to find the surface area of a square prism?(b) The height length of the prism is 10 cm and the base edge length is √15 cm.
We know the surface area is 2a²+4ah
Substitute the values
S = 2(√15)² + 4 (3.87 )(10)
= 2(15) + 40(3.87)
= 30 + 154.91
= 184.9 cm ²
Since the surface area of a square prism is 184.9 cm ².

[tex](3a + 2b - c)(a - b + 2c) \\ = (3 {a}^{2} - 3ab + 6ac + 2ab - 2 {b}^{2} + 6bc - ac + bc - 2 {c}^{2} ) \\ = 3 {a}^{2} - ab + 5ac - 2 {b}^{2} + 5bc - {2c}^{2} \\ = 3 {a}^{2} - 2 {b}^{2} - {2c}^{2} - ab + 5ac + 5bc[/tex]
Answer:
option a is correct
Step-by-step explanation:
(3a + 2b - c)(a - b + 2c)
3a(a- b + 2c) +2b(a - b + 2c) - c(a - b + 2c)
multiply the brackets
3a^2 - 3ab + 6ac + 2ab - 2b^2 + 4bc - ac + bc - 2c^2
combine like terms

would it be the same
Answers:
a) No, the figure would not look the same. See the diagram belowb) Yes the figure would look the same after a half turnc) Yes the figure would look the same after a full turn==================================================
Explanations:
a) The figure doesn't have 90 degree symmetry, so that's why we have a different looking figure after a quarter turn.b) The figure does have 180 degree symmetry. That's why it looks the same after a half turn (aka 180 degree turn)c) Rotating any figure 360 degrees, aka a full turn, will get everything back where it started. It doesn't matter if the figure has any symmetry or not.A restaurant owner is interested in the proportion of his customers who order dessert. He looks at 65 randomly selected receipts.

2. Variable
3. Sample
4. Data
5. Population
6. Parameter
Options E and F are repeated but the correct thing should be;
e. The list of the 65 Yes or No answers for whether each customer ordered dessert.
f. The answer: Yes or No to whether a customer ordered dessert
Answer:
a. Parameter
b. Population
c. Sample
d. Statistic
e. Data
f. Variable
Step-by-step explanation:
a. The proportion of all customers who order dessert: This is the parameter because it is the proportion of the population.
b. All customers who come to the restaurant: This is the population because it is from here that the sample was taken.
c. The 65 restaurant patrons whose receipts were observed by the owner: This is the sample because it was taken from the population.
d. The proportion of the 65 randomly selected customers who ordered dessert: This is the statistic because it represents a proportion of the sample.
e. The list of the 65 Yes or No answers for whether each customer ordered dessert: This is the data because it gives us information about the answers given.
f. The answer: Yes or No to whether a customer ordered dessert: This is the variable because it varies with with each customer.
Answer to the question
Answer:
(Opt.D) x = 14
Step-by-step explanation:
<A + <B = 180 (Adjacent angles of a parallelogram are supplementary)
∴36 + 11x - 10 = 180
26 + 11x = 180
11x = 180 - 26
11x = 154
x = 154/11
x = 14

I have one qt of solution diluted out 1:4 How much do I need to add to end up with a final product that’s a 1:10 solution?
Answer:
1.1352 L
Step-by-step explanation:
L = qt 1.0567
qt = 0.946 L
1:4 = 5
0.946/5 = 0.1892 L one part
0.1892 x 11 = 2.0812 11 parts as 1+10 =11
Answer therefore is subtracting 5 from 11 parts to get the final 6 parts added = 2.0812 - 0.946
= 1.1352 L

What is the measure of angle R
Answer: 37 degrees
Explanation:
We have a right triangle because the tangent is always perpendicular to the radius, at the point of tangency.
That then leads to angles P and R being complementary, ie they add to 90
P+R = 90
R = 90-P
R = 90-53
R = 37
Choose the equation and the slope of the line that passes through (3,-2) and is parallel to the x-axis. CHECK ALL THAT APPLY
A. Equation: x= 3
B. Equation: x = -2
C. Slope: undefined
D. Equation: y= 3
E. Slope: 0
F Equation: y= -2
Answer:
E. Slope: 0
F. Equation: y = -2
Step-by-step explanation:
✔️The x-axis is a horizontal line. Horizontal line does not have any rise, therefore, slope (m) of horizontal line is zero.
The line that is parallel to the x-axis would have a slope of 0 as well.
Therefore, slope (m) = 0
✔️Since the line passes through (3, -2) let's find the y-intercept (b) to enable us write the equation of the line.
Substitute (x, y) = (3, -2) and m = 0 into y = mx + b
-2 = 0(3) + b
-2 = 0 + b
b = -2
✅To write the equation of the line that is parallel to the x-axis, substitute m = 0 and b = -2 into y = mx + b:
y = 0(x) + (-2)
y = 0 - 2
y = -2

OB) x= 28
OC) x = 14
OD X=3
Answer:
x = 11
Step-by-step explanation:
X-7 = 4
Add 7 to each side
x-7+7 = 4+7
x = 11
Answer:
x=11
Step-by-step explanation:
Move the constant to the right -hand side and change its sign
x= 4+7
then add the numbers
x= 4+7
which =11

The frequency distribution below represents frequencies of actual low temperatures recorded during the course of a 31-day month. Use the frequency distribution to construct a histogram. Do the data appear to have a distribution that is approximately normal?
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]\begin{array}{cc}{Class} & {Frequency} & A\ 39-44 & 1 & B\ 45-50 & 3 & C\ 51-56 & 8 & D\ 57-62 & 6 & E\ 63-68 & 8 & F\ 69-74 & 3 & G\ 75-80 &2 \ \end{array}[/tex]
Solving (a): The histogram
To do this, we simply plot each data on each class on the x-axis and the frequency on the y-axis.
(See attachment for histogram)
Solving (b): The type of distribution
The histogram appears to have a bell shape. This means that the distribution is approximately normal.
