Answer:
Since the two angles, A and C are given to be 48° ang 46.7°, respectively, the value of angle B may be calculated by difference. Note that for a triangle, the sum of the angles is 180°. This makes the angle B equal to 85.3°. By the Sine Law,
b / sin B = a / sin A
Substituting,
b / sin 85.3° = 44 / sin 48°
The value of b from the equation is approximately equal to 59.01.

You volunteer to help drive children at a charity event to the zoo, but you can fit only 6 of the 15 children present in your van How many different groups of 6 children can you drive?
However if you are asking how many different combinations, there can be 5005 different combinations.
Answer:
2 different groups of 6 children.
Step-by-step explanation:
There are 15 children you need to bring. You can fit 6 children in each van.
One van : 6 children
Two vans : 12 children
Three vans : 18 children
If you take two vans, that will take 12 children. But you need to fit 15.
If you take three vans, that will take 18 children. This is more than enough.
15 children - 6 = 9 children
Thats one group with 9 children left to take
9 children - 6 = 3 children
Thats two groups with 3 children left to take
3 children - 6 = -3.
This doesn't work. In this case, there will be 3 more empty seats in the last group.
Since the question asks how many groups of 6 children you can drive. It would be two. Becuase there are 2 groups of 6 and one of 3.

As a result of inflation, the purchasing power of a fixed quantity of money decreases by 5% every year. If a certain quantity of money can buy 940 frozen dinners this year, how many frozen dinners can it buy in 16 years?
There would be 413 frozen dinners in the next 16 years.
How to solve an exponential function?Let y represent the amount of frozen dinners after x years.
If a certain quantity of money can buy 940 frozen dinners this year, and it decreases by 5% every year, hence:
y = 940(0.95)ˣ
In 16 years:
y = 940(0.95)¹⁶
y = 413.71
There would be 413 frozen dinners in the next 16 years.

Step-by-step explanation:
Answer:
(2, -4)
Step-by-step explanation:
The solution to a system of equations is always going to be the point(s) where they intersect. To solve, use substitution and find each variable, x and y. Our final answer will be a set of coordinates (x, y). To plot this system, see the help image attached.
y = -x - 2
2x - y = 8
Substitute y to find x
2x - (-x - 2) = 8
2x + x + 2 = 8
3x = 6
x = 2
Substitute x to find y
y = -(2) - 2
y = -2 - 2
y = -4

Do comment if you have any query.
Answer:
y = m x + b is the standard form for a straight line
you have
y = 6 x + b if m = 6
Now when x = 2, y = -8 this is given
- 8 = 6 * 2 + b substituting given values
b = -8 - 12 = -20
y = 6 x -20 is the equation requested
Check;
-8 = 6 * 2 - 20
12 = 12 so this agrees
In a word processing document or on a separate piece of paper, use the guide to construct a two column proof proving AEC ≅ DEB, given that CA is parallel to DB and E is the midpoint of AD. Submit the entire proof to your instructor.
Given:
CA || DB
E is the midpoint of AD
Prove:
AEC ≅ DEB
A two column proof for ΔAEC ≅ ΔDEB is as shown below.
What are congruent triangles?"Two triangles are congruent if all three corresponding sides are equal and all the three corresponding angles are equal in measure."
What are interior angles?"These angles formed on the inside of two straight lines when crossed by a transversal."
What is midpoint?"It is point which divides a line segment into two equal parts."
What is AAS postulate of triangle congruence?"AAS (Angle Angle Side) theorem states that in the two triangles, if two angles and one side of a triangle are congruent to two angles and one side of a second triangle, then the two triangles are congruent."
For given question,
Given that CA is parallel to DB and E is the midpoint of AD.
CA is parallel to DB
CB is transversal.
∠ACB and ∠CBD are alternate interior angles.
We know that when a transversal intersects a parallel line then alternate interior angles formed are congruent.
So, ∠ACB ≅ ∠CBD ................(i)
Similarly for CA || DB and AD is transversal.
∠CAD ≅ ∠ADB ..................(ii)
Also, E is the midpoint of AD.
By definition of midpoint,
⇒ AE = ED ..................(iii)
From (i), (ii) and (iii),
By AAS postulate of triangle congruence,
ΔAEC ≅ ΔDEB
Therefore, a two column proof for ΔAEC ≅ ΔDEB is as shown below.

At the market, 2.4 pounds of peas cost
$1.68. How much does one pound of
peas cost?
$0.7
Step-by-step explanation:Given sentence:
2.4 pounds of peas cost $1.68.Writing as an equation:
[tex]\implies 2.4 \ \text{pounds} = \$1.68[/tex]
To obtain the cost per pound of peas, divide 2.4 both sides. This will convert the value on the L.H.S to 1 pound. The value obtained on the R.H.S will be the the cost (answer).
[tex]\implies \dfrac{2.4 \ \text{pounds}}{2.4} = \$\dfrac{1.68}{2.4}[/tex]
[tex]\implies 1 \ \text{pounds}}= \$\dfrac{1.68}{2.4}[/tex]

The probability that a meal at a restaurant is overcooked is 10%. Estimate the probability that exactly 1 of the next 2 meals is overcooked.
Answer:
The probability that exactly 1 of the next 2 meals is overcooked = 3.34%
Step-by-step explanation:
The probability that a meal at a restaurant is overcooked is 10%
The probability that exactly 1 of the next 2 meals is overcooked = out of 3 meals 1 meal is overcooked of 10%
= 1 × 3 × 10%
= 10 × 3 %
= 3.34 %
Answer: 18.1%
Step-by-step explanation:
[tex]P($ overcooked $)=1 / 10$ \\$P($ exactly one overcooked of next two)\\\begin{$aligned}&\Rightarrow O N+N O \quad\left[\begin{array}{l}O \rightarrow \text { Overcooked } \\N \rightarrow \text { Not Overcooked}\end{array}\right. \\&\Rightarrow P(O) \cdot P(N)+P(N) P(O)\end{aligned}$$[/tex]

The Ruiz family is exchanging euros for US dollars. The exchange rate is 1 euro equals 1.35261 USD. Since the Ruiz family knows that USD are stated to the nearest hundredth of a dollar, they used the conversion ratio. Will this give the Ruiz family the correct
The Ruiz family using a rounded figure for exchange rate will not give the correct exchange.
Exchange rate:
1 euro = 1.35261 USD
1.35261 rounded to the nearest hundredth = 1.35
If Ruiz family is exchanging 50 euros for instance
Original exchange rate
1 euro = 1.35261 USD
50 euro = 67.6305
Rounded exchange rate:
1 euro = 1.35 USD
50 euro = 67.5 USD
Therefore, the Ruiz family using a rounded figure for exchange rate will not give the correct exchange.

then factor the remaining
multiply number next to x^2 which is a with 196 which is c
