Step-by-step explanation:
Use the Law of Cosines to find the measure of segment c:
[tex]c=\sqrt{a^2+b^2-2ab*cos(C)}\\\\c=\sqrt{12^2+13^2-2(12)(13)*cos(134)}\\\\c=\sqrt{313-312cos(134)}\\\\c=\sqrt{313-312(-.6946583705)}\\\\c=\sqrt{313-(-216.7334116)}\\\\c=\sqrt{313+216.7334116}\\\\c=\sqrt{529.7334116}\\[/tex]
c ≈ 23.01593821 km ≈ 23 km
Since c = 23 km, our only options are choices B and D. Now, let's find the measure of angle A to confirm. To do this we will use the Law of Sines:
[tex]\frac{sin(A)}{a} =\frac{sin(C)}{c} \\\\\frac{sin(A)}{12}=\frac{sin(134)}{23.01593821}\\\\sin(A)=12(\frac{sin(134)}{23.01593821})\\\\A=sin^{-1}[12(\frac{sin(134)}{23.01593821})]\\\\[/tex]
A ≈ 22.02726885° ≈ 22°
Since the measure of c = 23 km and the measure of angle A = 22°, the answer must be choice B.

Find a formula for the n th term, T n , of the following arithmetic sequence: − 10 , − 22 , − 34 , − 46 ,. . . Hence, or otherwise, find the value of the 40th term, T 40
Answer:
T(40) = -478
Step-by-step explanation:
The first term is -10, that means a = -10
The difference between to first and second term is -12.
Therefore, d = -12.
We may set up the A.S. equation now:
T(n) = a + (n-1)d = -10 + (n-1)(-12)
Now plug in n = 40:
T(40) = -10 + (40-1)(-12) = -478

Answer:
a = 16
b = 10
c = 19
d = 3
Step-by-step explanation:
For a, we know that 60 is 12+a+a+a, and to find what a is, we subtract 12 from 60, so that 48=3a, so 48 is a times 3. dividing 48 by 3 gives a=16
For b, we know that 60 is 4(b+5), dividing both sides by 4, 15=b+5. Subtracting 5 from both sides, b=10
For c, we know that a+b+c=3(b+5), or 16+10+c=45, subtracting 26 from each side, c=19
For d, we know that 3c+d=60, or (19*3)+d=60. simplifying, 57+d=60. subtraction 57 from each side gives d=3

Determine between which two whole numbers lies square root of 20
The square root of 20 is between 4 and 5.
Whole NumbersThey are the numbers represented by positive real numbers where the fractions and decimal numbers are not included.
For solving this question, you should list the whole numbers whose your square is less than 30. Your list must present the following numbers:
0 ⇒ 0²=0
1 ⇒ 1²=1
2 ⇒ 2²=4
3 ⇒3²=9
4 ⇒ 4²=16
5 ⇒ 5²=25
Note that 6²=36, it is greater than 30,because of this it is not in the previous list.
The question asks to determine between which two whole numbers lies the square root of 20. Therefore, from the previous list, it is possible to see that the value 20 is between 16 and 25. The square root of 16 and 25 is equal to 4 and 5, respectively.
Thus, the square root of 20 is between 4 and 5. You can check this results in your calculator:[tex]\sqrt{20}=2\sqrt{5}=4.47[/tex]

(a) 6x2 + 2x - 3-x +4.7 - 1
(6) 6.x2 + 2x-3-(x2 + 4x - 1)
Answer:
a. 6x^2+x+0.7
b. 5x^2-2x-2
Step-by-step explanation:
a. 6x^2+2x-3-x+4.7-1
Simplest form is when all the terms are ordered by power and like terms are combined. I'm assuming the first term is 6x^2 because 6x2 seems a bit odd to me. When you combine like terms and reorder everything, you get
6x^2+x+0.7
b. 6x^2+2x-3-x^2-4x+1
The first thing I did was distribute the negative. Next, you just repeat the same steps. Combine like terms and reorder. The final result is:
5x^2-2x-2
Determine whether it is possible to form a triangle with the given side lengths.
AB= 4 cm, BC= 6 cm, AC= 12 cm
Answer:
No, not possibleStep-by-step explanation:
According to triangle inequality, any side is less than the sum of the other two:
AB + BC > ACWe see contradiction with above when values substituted:
4 + 6 = 10 < 12It means we can't form a triangle with given sides

Gabriel used the expression 2. 5x 2y – 2 to represent his total cost, and 28 – 2. 5x – 2y to represent the amount of change he should receive from $30. What was Gabriel’s error?
The error made by the Gabriel in calculating the change amount, is that he subtract the $2 instead of adding $2.
What is algebraic expression?
Algebraic expression are the expression which consist the variables, coefficients of variables and constants.
The algebraic expression are used represent the general problem in the mathematical way to solve them.
The expression used by the Gabriel to represent his total cost is,
[tex]2.5x+2y - 2[/tex]
As, Gabriel has to receive the change amount of $30. Thus, he has to subtract this amount from the total cost. This statement can be present as,
[tex]\rm Change=30-(2.5x+2y - 2)\\\rm Change=30-2.5x-2y + 2\\\rm Change=32-2.5x-2y[/tex]
Now, the expression used by him to represent the amount of change he should receive from $30 is,
[tex]28 -2.5x - 2y[/tex]
Hence, the error made by the Gabriel in calculating the change amount, is that he subtract the $2 instead of adding $2.

Answer:
1134.08 m²
Step-by-step explanation:
To calculate the area of grass, subtract the area of the polygon from the area of the large green rectangle.
area of a triangle = 1/2 x base x height
area of a rectangle = width x length
area of large (green) rectangle = 40 x 36 = 1440 m²
area of regular 8-sided polygon = 4 triangles + 2 small rectangles + large rectangle
= 4(1/2 x 5.6 x 5.6) + 2(8 x 5.6) + (8 x 19.2) = 305.92 m²

(3, 5) and (–4, 12)
(–3, 11) and (4, 4)
(4, 4) and (5, 3)
(12, –4) and (7, 1)
Answer:
(3, 5) and (-4, 12)
Step-by-step explanation:
To solve this system of equations, we'll use the substitution method.
Plug in the given y = x² - 4 into the other equation
x + x² - 4 = 8
Subtract 8 from both sides
x² + x - 4 = 8
- 8 - 8
x² + x - 12 = 0
Factor out the equation
x² + x - 12 = (x + 4)(x - 3) = 0
For the equation to be 0, x will have to equal -4 and 3
Now plug in the new x's into one of the original equations
We'll use y = x² - 4
y = (-4)² - 4 = 16 - 4 = 12
y = 3² - 4 = 9 - 4 = 5
When x = -4, y = 12, so one of the answers is (-4, 12)
When x = 3, y - 5, so one of the answers is (3, 5)

Priya spends $42 a week on coffee and donuts across 5 days. She
spends the same amount on doughnuts each day. If she spends 30 dollars on coffee, how much does
she spend on doughnuts each day?
Pls help
If she spends $42 a week on coffee and every day she spends the same amount (I don't see this in the question, only doughnuts.), then $30 can get her 30 : 42 = 5/7 of a week of coffee -> 5 days.
So, she spends 5 days on coffee -> she must also spend 5 days on doughnuts
And since she spends 30 dollars equally everyday, she spends 30 : 5 = $6 everyday on doughnuts
Hamad sells fruits in his shop. One morning, he got 2 boxes of apples from 2 different
suppliers.
The label on the first box says that it contains 50 apples with a total weight of 6300 g.
The label on the second box says that it contains 40 apples, and has a mean weight
of an apple of 144 g.
Hamad put all the apples from both boxes in one big container.
Find the mean weight of an apple in the big container.
The weight of all 40 apples in the second box is : 144 x 40 = 5760 (g)
The total weight of all 90 apples in both boxes : 5760 + 6300 = 12060 (g)
To find the mean weight of an apple in the big container, we take the total weight of both boxes (12060) divided by the total amount of quantities (apples in both boxes)
So, the mean weight of an apple in the big container is 12060 : 90 = 134(g)
the top box has a length of 6 yards
Answer:
42 yd²
Step-by-step explanation:
Area of a rectangle = width x length
lateral surface area is the area of the sides only
So the difference between the total surface area and the lateral surface area would be the surface area of the ceiling and floor (top and bottom).
area of floor and ceiling = 2(3.5 x 6) = 42 yd²
Or, we can calculate the total surface area and lateral surface area, then find the difference:
total surface area = 2(3.5 x 4.2) + 2(4.2 x 6) + 2(3.5 x 6) = 121.8 yd²
lateral surface area = 2(3.5 x 4.2) + 2(4.2 x 6) = 79.8 yd²
difference = 121.8 - 79.8 = 42 yd²
