Answer:
t12= -8
Step-by-step explanation:
t3
a+2d=10 (1)
t10
a+9d=-4. (2)
From (1)
a=10-2d. (3)
Sub into (3) into equ (2)
a+9d=-4
10-2d+9d=-4
10+7d=-4
7d=-4-10
7d=-14
Divide both sides by 7
d=-14/7
d= -2
10=a+2d
10=a+2(-2)
10=a-4
10+4=a
14=a
a=14
t12=a+11d
= 14+11(-2)
=14-22
= -8
t12= -8

A jar contains 4 red marbles, 6 blue marbles, 3 yellow marbles, and 5 green marbles. If one marble is randomly selected, what is the probability that it is red or green?
Answer:
1/2
Step-by-step explanation:
4 red marbles, 6 blue marbles, 3 yellow marbles, and 5 green = 18 marbles
P( red or green) = red or green / total
= (4+5) / 18
= 9/18
=1/2
Answer:
50%
Step-by-step explanation:
4 red + 5 green = 9 marbles
total marbles = 18 marbles
9 is 50% of 18

Find Sn for the given arithmetic series.
Q1 = -40, d =-7, n=22
Answer:
[tex]S_n =[/tex] -2497
Step-by-step explanation:
We are given an arithmetic series with the following terms:
First term, [tex]Q_1[/tex] = -40
Common difference, d = -7
Number of terms, n = 22
To find out: Sum of n terms, where n is 22
We know that Sum of n terms in an arithmetic series is given as:
[tex]S_n =\dfrac{n}{2} (2Q_1+(n-1)d)[/tex]
Putting the values in the formula:
[tex]S_{22} = \dfrac{22}{2} (2 \times -40+(22-1)\times (-7))\\\Rightarrow S_{22} = 11 \times (-80-147)\\\Rightarrow S_{22} = 11 \times (-227)\\\Rightarrow S_{22} = -2497[/tex]
So, the sum of 22 terms is -2497.

Step-by-step explanation:
To solve via calculator, go to the MATH menu, then the 0th option should say "summation" and insert it from there.
To solve algebraically, break the summation into 2 parts. Excuse the strange formatting, I can't find a way to do it normally.

How many cubes eith side lengths of 1/4 cm does it take to fill the prism? Please help
Step-by-step explanation:
In order to find Volume for a rectangle use the formula: L * W * H
2 1/4 * 3/4 * 1 1/4 = 2 7/64
A cube with the side lengths of 1/4: 1/4 * 1/4 * 1/4 = 1/64
Divide 1/64, by the prisms volume, 2 7/64 to get 135.

Pamela and her friend Nicole are each baking apple pies and tarts for a bake sale, using the same recipes. Pamela baked 5 apple pies and 7 apple tarts, using a total of 68 apples. Nicole made 5 apple pies and 9 apple tarts, which used 76 apples. How many apples does each dessert require?
Answer:
Each apple pie requires 8 apples, and each apple tart requires 4 apples.
Step-by-step explanation:
We see that both Pamela and Nicole bake the same amount of apple pies, but different amounts of apple tarts. Because of this, we can subtract the two to try to figure out the amount of apples for each apple tart. We subtract 68 from 76, giving us 8. Nicole baked 9 apple tarts, while Pamela baked 7, and 9-7=2. So we can bake two apple tarts with 8 apples, so one apple tart requires 4 apples (we divide by 2). Now that we know the amount of apples per each apple tart, we multiply 7 apple tarts that Pamela made by 4 apples, giving us 28. We subtract that from the total amount of apples Pamela used, which was 68, giving us 40. From this we can deduct that 5 apple pies need 40 apples, and we divide by 5, giving us 1 apple pie requires 8 apples.

A healthy human body is approximately 18% carbon by weight. Determine how many pounds of carbon a body weighing 200 lbs contains. How many kilograms would that be? Use 0.454 kg equals 1 lb in your conversion. A. 440 lb. Of carbon; 16 kg of carbon b. 36 lb. Of carbon; 79 kg of carbon c. 36 lb. Of carbon; 16 kg of carbon d. 440 lb. Of carbon; 79 kg of carbon
Answer:
c. 36 lb. Of carbon; 16 kg of carbon
Step-by-step explanation:
An healthy body is approximately 18% carbon by weight. To determine how many pounds of carbon a body weighing 200Ibs contain can be gotten below.
A healthy person has approximately 18% carbon by weight. Therefore, the number of pounds of carbon for a person weighing 200 Ibs is
pounds of carbon = 18/100 × 200
pounds of carbon = 36 Ibs
According to the question the weight should be in kg.Therefore, we have to convert using the conversion rate you highlighted.
1 Ib = 0.454 kg
36 Ibs = ? kg
cross multiply
weight of carbon in kg = 0.454 × 36
weight of carbon in kg = 16.344 kg
weight of carbon in kg ≈ 16 kg
find the coordinates of the vertices of the triangle after a reflection across the line y= 3 and then across the line x = -1
Answer: A
Step-by-step explanation:
Reflection across y = 3
The simplest way to calculate the new coordinates is to draw y = 3, count how many units away the point is from y = 3, then count the same number of units from y = 3 in the OPPOSITE direction to find the reflection. (see attachment - blue color)
U = (-5, 4) is 1 unit above y = 3
U' = (-5, 2) is 1 unit below y = 3
T = (0, 5) is is 2 units above y = 3
T' = (0, 1) is 2 units below y = 3
S = (-4, 2) is 1 unit below y = 3
S' = (-4, 4) is 1 unit above y = 3
Reflection across x = -1
The simplest way to calculate the new coordinates is to draw x = -1, count how many units away the point is from x = -1, then count the same number of units from x = -1 in the OPPOSITE direction to find the reflection. (see attachment - red color)
U' = (-5, 2) is 4 units to the left of x = -1
U'' = (3, 2) is 4 units to the right of x = -1
T' = (0, 1) is 1 unit to the right of x = -1
T'' = (-2, 1) is 1 unit to the left of x = -1
S' = (-4, 4) is 3 units to the left of x = -1
S'' = (2, 4) is 3 units to the right of x = -1

The area of triangle is 1/5 feet².
Step-by-step explanation:
You have to use area of triangle formula, A = 1/2×height×base. Then substitute the following values into the formula :
[tex]area = \frac{1}{2} \times height \times base[/tex]
Let height = 3/5,
Let base = 2/3,
[tex]area = \frac{1}{2} \times \frac{3}{5} \times \frac{2}{3} [/tex]
[tex]area = \frac{1}{2} \times \frac{1}{5} \times \frac{2}{1} [/tex]
[tex]area = \frac{1}{2} \times \frac{2}{5} [/tex]
[tex]area = \frac{1}{5} {feet}^{2} [/tex]

Factor
What two numbers multiply to -3 and add to -4
-3*-1 = 3
-1+-1 = -4
(x-3)(x-1) =0
Using the zero product property
x-3 =0 x-1 =0
x=3 x=1
Answer:
lesser x = 1
greater x = 3
Step-by-step explanation:
x^2 - 3x - x + 3 = 0
x(x - 3) - 1(x - 3) = 0
= (x - 3)(x - 1) =0
= x = 3, 1

Which statements are true? Check all that apply. Magnitude is never a negative value. The magnitude of –1.9 is |–1.9| which is 1.9. The absolute value of a number is greater than its magnitude. The numbers –4 and 4 have the same magnitude. The magnitude of Negative two-thirds is less than the magnitude of Two-thirds.
Answer:
A, B, D
Step-by-step explanation:
The options are:
A. Magnitude is never a negative value
This is true because the magnitude is only a representation of the numerical value of a number. It is the distance of the number from the 0 point on the number line. It is the absolute value of a number.
Hence, the polarity of the number is not necessary.
B. The magnitude of –1.9 is |–1.9| which is 1.9
This is true because they have the same numerical value.
C. The absolute value of a number is greater than its magnitude
This is false because absolute value and magnitude of a number are the same.
D. The numbers –4 and 4 have the same magnitude
This is true. They have the same absolute value, hence, they have the same magnitude.
E. The magnitude of -2/3 is less than the magnitude of 2/3
This is false as already explained in C above.

On a particular day in July, there is a 20% probability of rain in Vancouver, a 65% probability of rain in Calgary, and a 75% probability of rain in Saskatoon. What is the probability that it will rain in all 3 cities on that day?
Answer:
The probability that it will rain in all 3 cities on that day
P(V∪ C∪S) = 0.93 = 93%
Step-by-step explanation:
Let 'V' be the event of rain in Vancouver
Given that the probability of rain in Vancouver
P( V) = 20% = 0.20
P( V⁻) = 1- P( V) = 1 - 0.20 =0.80
Let 'C' be the event of rain in Calgary
Given that the probability of rain in Calgary
P( C) = 65% = 0.65
P( C⁻) = 1- P( C) = 1 - 0.65 =0.35
Let 'S' be the event of rain in Saskatoon
Given that the probability of rain in Saskatoon
P( S) = 75% = 0.75
P( S⁻) = 1- P( S) = 1 - 0.75 =0.25
First we will prove that the probability that it will not rain in all 3 cities on that day
P( V⁻ ∩ C⁻ ∩ S⁻ ) = P( V⁻) P( C⁻) P(S⁻)
= 0.80 × 0.35 × 0.25
= 0.07
The probability that it will rain in all 3 cities on that day
P(V∪ C∪S) = 1-(P( V⁻ ∩ C⁻ ∩ S⁻ )
= 1 - 0.07
= 0.93

Answer: 176m^2
Step-by-step explanation:
The smaller rectangle is taking up space among the larger one. So in order to find the area of this shaded region, you need to subtract that smaller one from the larger one.
12 x 15 = 180
1 x 4 = 4
180 - 4 = 176m^2
Answer:
44
Step-by-step explanation:
To start you have to calculate the perimeter of the white box. 1 times 2 is 2. 4 times two is 8. 8 plus 2 is 10. Then you have to find the perimeter of the purple box. 12 times 2 is 24. 15 times 2 is 30. 24 plus 30 is 54. After that you have to subtract to get the final answer. 54 minus 10 in 44. 44 is the final answer.
