Answers
Answer:
The area of trapezium is (x+11) cm².
Step-by-step explanation:
Given that the formula of area of trapezium is :
[tex]area = \frac{1}{2} \times (a + b) \times h[/tex]
In the formula, a and b represents the length of trapezium and h is the height. So you have to substitute the following expressions into the formula :
[tex]let \: a = 5 \\ let \: b = x + 6 \\ let \: h = 2[/tex]
[tex]area = \frac{1}{2} \times (5 + x + 6) \times 2[/tex]
[tex]area = \frac{1}{2} \times 2 \times (x + 11)[/tex]
[tex]area = 1 \times (x + 11)[/tex]
[tex]area = (x + 11) \: {cm}^{2} [/tex]
Answer:
Area = x+11
Step-by-step explanation:
[tex]A = \frac{1}{2} (a+b)h\\Base =5\\Height =2\\Base =x+6\\A = \frac{5+(x+6)}{2} \times 2\\A = \frac{5+x+6}{2} \times 2\\ A =\frac{x+11}{2} \times 2\\Area= x+11[/tex]

Answer:
D) A statement not formed by exchanging the hypothesis and conclusion of the conditional is not a converse statement. True
Step-by-step explanation:
Information is missing in the question, which would be the following:
A converse statement is formed by exchanging the hypothesis and conclusion of the conditional.
The options for answering the question are also missing, which by investigating I could know that they are as follows:
A) a non-converse statement is not formed by exchanging the hypothesis and conclusion of the conditional. True
B) A statement not formed by exchanging the hypothesis and conclusion of the conditional is a converse statement. False; an inverse statement is not formed by exchanging the hypothesis and conclusion of the conditional.
C) A non-converse statement is formed by exchanging the hypothesis and conclusion of the conditional. False; an inverse statement is formed by negating both the hypothesis and conclusion of the conditional.
D) A statement not formed by exchanging the hypothesis and conclusion of the conditional is not a converse statement. True
Now we have that a conditional statement has the form of whether A then B.
Also, A contradictory statement is when we exchange the hypothesis and the conclusion of the sentence and deny them both. It has the following form if not A, then not B.
Therefore the answer is D)

If point C divides AB in the ratio 2 : 3, the coordinates of point C are (_,_). If point D divides AC in the ratio 3 : 2, the coordinates of point D are (_,_). help plz!
Answers
Answer:
- The coordinates of C is (3,2)
- The coordinates of D is (11/5,14/5)
Step-by-step explanation:
Given
A(1,4) and B(6,-1)
Required
a. Point C divide AB in ratio 2:3
b. Point D divide AC in ratio 3:2
When endpoints are divided into ratios, the formula to calculate the coordinates is;
[tex](x,y) = (\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n})[/tex]
Solving for (a): Point C divide AB in ratio 2:3
The ratio;
[tex]m : n = 2 : 3[/tex]
For Point A;
[tex]A(x_1,y_1) = (1,4)[/tex]
For Point B;
[tex]B(x_2,y_2) = (6,-1)[/tex]
Substitute m,n,x1,x2,y1,y2 in the ratio formula given above;
[tex]C(x,y) = (\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n})[/tex]
[tex]C(x,y) = (\frac{2 * 6 + 3 * 1}{3+2},\frac{2 *-1 + 3 * 4}{3+2})[/tex]
[tex]C(x,y) = (\frac{12 + 3 }{5},\frac{-2 + 12}5})[/tex]
[tex]C(x,y) = (\frac{15 }{5},\frac{10}5})[/tex]
[tex]C(x,y) = (3,2)[/tex]
The coordinates of C is (3,2)
Solving for (b): Point D divide AC in ratio 3:2
Using the same steps as (a) above;
The ratio;
[tex]m : n = 3:2[/tex]
For Point A;
[tex]A(x_1,y_1) = (1,4)[/tex]
For Point C;
[tex]C(x_2,y_2) = (3,2)[/tex]
Substitute m,n,x1,x2,y1,y2 in the folowing ratio formula;
[tex]D(x,y) = (\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n})[/tex]
[tex]C(x,y) = (\frac{3 * 3 + 2 * 1}{2+3},\frac{3 *2 + 2 * 4}{2+3})[/tex]
[tex]D(x,y) = (\frac{9 + 2}{5},\frac{6 + 8}{5})[/tex]
[tex]D(x,y) = (\frac{11}{5},\frac{14}{5})[/tex]
The coordinates of D is (11/5,14/5)

10) Spike drives for 50 miles at 60mph. He slows down and travels
another 50 miles at 40mph. For the final part of the 120 mile journey,
he speeds up to 80mph. How long does he take altogether? What is
his average speed (to the nearest mph)?
Answers
Answer:
2 1/3 hours or 2 hours 20 minutes.
51.4 mph to 1 decimal place.
Step-by-step explanation:
Time = distance speed
First 50 miles time taken = 50 / 60 = 5/6 hours
Second 50 miles - time = 50/40 = 5/4 hours.
Final 20 miles - time taken = 20 / 80 = 1/4 hours.
Total time taken = 5/6 + 5/4 + 1/4
= 5/6 + 6/4
= 10/12 + 18/12
= 28/12
= 7/3 or 2 1/3 hours or 2 hours 20 minutes.
Average speed = total distance / total time
= 120 / 7/3
= 120 * 3/7
= 51.4 mph to 1 decimal place.
Which of the following is not a condition that must be met before you can use
the quadratic formula to find the solutions of an equation?
Answers
Answer:
D. The coefficient of the x^2-term must be positive.
Step-by-step explanation:
A. The coefficient of the x2-term can't be zero.
B. There can be no term whose degree is higher than 2.
C. One side of the equation must be zero.
D. The coefficient of the x2-term must be positive.
Quadratic equation is given as:
y=ax^2+bx+c
To use the quadratic formula,we have
ax^2+by+c=0
Coefficient of x^2 can not be equal to 0, that is a can not be equal to 0
There can be no term whose degree is higher than 2. The highest degree in a quadratic equation is 2
One side of the equation must be 0, that is ax^2+by+c=0
Coefficient of x^2 must be positive. The coefficient of x^2 can either be positive or negative. That is, it can either be a or -a

The volume of the triangular block is 4 cubic inches. What is the approximate length of y? Round to the nearest 10th of an inch.
Answers
Answer:
2.8 in
Step-by-step explanation:
The volume (V) of the prism is calculated as
V = Ah ( A is the area of the triangular end and h is the length )
A = [tex]\frac{1}{2}[/tex] × x × x = [tex]\frac{1}{2}[/tex] x² , thus
V = [tex]\frac{1}{2}[/tex] x² × x = 4 , that is
[tex]\frac{1}{2}[/tex] x³ = 4 ( multiply both sides by 2 )
x³ = 8 ( take the cube root of both sides )
x = [tex]\sqrt[3]{8}[/tex] = 2
Using Pythagoras' identity on the right triangle with hypotenuse y, then
y² = x² + x² = 2² + 2² = 4 + 4 = 8 ( take the square root of both sides )
y = [tex]\sqrt{8}[/tex] ≈ 2.8 in ( to the nearest tenth )

Answer: Bill has 12 cards
Alan and Calvin both have 19 cards each.'
Step-by-step explanation:
Let x= Number of cards Bill has.
Then Alan has cards = [tex]2\dfrac{1}{2}x-11=\dfrac{5}{2}x-11[/tex]
Calvin has cards = [tex]1\dfrac{1}{2}x+1=\dfrac{3}{2}x+1[/tex]
Since Alan and Calvin has equal number of cards.
Then, [tex]\dfrac{5}{2}x-11=\dfrac{3}{2}x+1[/tex]
[tex]\Rightarrow\ \dfrac{5}{2}x-\dfrac{3}{2}x=1+11\\\\\Rightarrow\ \dfrac{5-3}{2}x=12\\\\\Rightarrow\ \dfrac{2}{2}x=12\\\\\Rightarrow\ x=12[/tex]
So, Bill has 12 cards
Then, Alan has cards = [tex]\dfrac{5}{2}(12)-11=30-11=19[/tex]
Calvin has cards = [tex]\dfrac{3}{2}(12)+1=18+1=19[/tex]
So, Alan and Calvin both have 19 cards each.

Answers
Answer:
First graph = 2/9
Second graph = 3/7
Third graph = 1/5
Step-by-step explanation:
Unit rate can be defined as number of y units changed with respect to the number of x units changed.
Consider the first graph, we can see that for x=9, the change that occurs in y is equals to 2 units. So its units can be given as 2/9
Consider the second graph, we can see that for x=7, the change that occurs in y is equals to 3 units. So its units can be given as 3/7
Consider the third graph, we can see that for x=5, the change that occurs in y is equals to 1 units. So its units can be given as 1/5.

Step-by-step explanation:
The inequality is 0.04m + 10 ≥ 69.48. We use ≥ and not > because it says "least", indicating that we need to use the ≥ sign. Solving for m we get:

The sequence 15, 21, 27, 33, 39, ...., 75 has 11 terms. Evaluate the related series.

b.) 495
c.) 0210
d.) 480
Answers
Answer:
b. 495
Step-by-step explanation:
Given
15, 21, 27, 33, 39, ...., 75
Number of terms = 11
Required
Evaluate
To evaluate means to add up all term of the series above;
The first step is to determine if the series is arithmetic or exponential;
If its arithmetic, then the difference between successive terms must be equal;
In other words;
21 - 15 = 27 - 21 = 33 - 27 = 39 - 33 = 6
Since the result of the above expression gives 6, then it is an arithmetic series;
The sum of n terms of an arithmetic series is calculated as this
[tex]S_n = \frac{n}{2}(a + T_n)[/tex]
Where n = 11
a = First term = 15
T_n = Last term = 75
The formula becomes
[tex]S_{11} = \frac{11}{2}(15 + 75)[/tex]
[tex]S_{11} = \frac{11}{2}(90)[/tex]
[tex]S_{11} = \frac{11 * 90}{2}[/tex]
[tex]S_{11} = \frac{990}{2}[/tex]
[tex]S_{11} = 495[/tex]
Hence, the series when evaluated is 495

Consider a game in which players roll a number cube to determine the number of points earned. If a player rolls a prime number, that many points will be added to the player’s total. Any other roll will be deducted from the player’s total. What is the expected value of the points earned on a single roll in this game?
Answers
Answer:
The expected value of the points earned on a single roll in this game is [tex]\dfrac{1}{6} = 0.1667[/tex] .
Step-by-step explanation:
We are given that consider a game in which players roll a number cube to determine the number of points earned. If a player rolls a prime number, that many points will be added to the player’s total. Any other roll will be deducted from the player’s total.
Assuming that the numbered cube is a dice with numbers (1, 2, 3, 4, 5, and 6).
Here, the prime numbers are = 1, 2, 3 and 5
Numbers which are not prime = 4 and 6
This means that if the dice got the number 1, 2, 3 or 5, then that many points will be added to the player’s total and if the dice got the number 4 or 6, then that many points will get deducted from the player’s total.
Here, we have to make a probability distribution to find the expected value of the points earned on a single roll in this game.
Note that the probability of getting any of the specific number on the dice is [tex]\dfrac{1}{6}[/tex] .
Numbers on the dice (X) P(X)
+1 [tex]\frac{1}{6}[/tex]
+2 [tex]\frac{1}{6}[/tex]
+3 [tex]\frac{1}{6}[/tex]
-4 [tex]\frac{1}{6}[/tex]
+5 [tex]\frac{1}{6}[/tex]
-6 [tex]\frac{1}{6}[/tex]
Here (+) sign represent the addition in the player's total and (-) sign represents the deduction in the player's total.
Now, the expected value of X, E(X) = [tex]\sum X \times P(X)[/tex]
= [tex](+1) \times \frac{1}{6} +(+2) \times \frac{1}{6} +(+3) \times \frac{1}{6} +(-4) \times \frac{1}{6} +(+5) \times \frac{1}{6} +(-6) \times \frac{1}{6}[/tex]
= [tex]\frac{1}{6} + \frac{2}{6} + \frac{3}{6} - \frac{4}{6} + \frac{5}{6} - \frac{6}{6}[/tex]
= [tex]\frac{1+2+3-4+5-6}{6}[/tex]
= [tex]\frac{11-10}{6}= \frac{1}{6}[/tex]
Hence, the expected value of the points earned on a single roll in this game is [tex]\frac{1}{6} = 0.1667[/tex] .
