find the area of the shaded region
(the number is 8 for anyone not able to read it)
Answers
Answer:
≈ 18.3 m²
Step-by-step explanation:
The shaded area (A) is calculated as
A = area of sector - area of right triangle
area of sector = area of circle × fraction of circle
A = πr² × [tex]\frac{90}{360}[/tex]
= π × 8² × [tex]\frac{1}{4}[/tex] = 64π × [tex]\frac{1}{4}[/tex] = 16π m²
area of triangle = [tex]\frac{1}{2}[/tex] × 8 × 8 = 4 × 8 = 32 m²
shaded area is then
A = 16π - 32 ≈ 18.3 m² ( to the nearest tenth )

Halen wrote the product 0.4 for the problem at the right. Don says that is not correct because when you multiply tenths by tenths, the product will be in the hundredths. Is Don right? Explain.
Answers
Answer:
Helen is correct and Don is wrong
Step-by-step explanation:
Halen wrote the prodect 0.4 for the problem .5×.8. Don says that is not correct since when you multiply tenths by tenths the product will be in the hundreths. Is Don right?
.5 × .8 = 0.4
Helen is correct
Don is wrong because the zero(0) at the end of decimals are usually ignored
Such as: 0.10 ; it is usually written as 0.1
Same thing goes for 0.40 which is written as 0.4
Therefore, Helen is correct and Don is wrong

Answer:

180=90+38+x
where x equals missing angle
x=52
Step-by-step explanation:
Hello There!
remember the sum of the interior angles of a triangle is 180
so to find the measure of the missing angle we subtract the given angles from 180
180-90-38=52
so the measure of the missing angle is 52
round off 45682 in two significant figure
Answers
Answer:
Rounded it's 46,000
Step-by-step explanation:
Explanation:
In “45682”
‘5’ is the second significant figure.
While rounding off, we have to check the number behind the one chosen, in this case 5 is chosen. So we will look at the one behind 5 which is 6.
As 6 is larger than 5, we will round up.
The answer is 46000
Brief notes:
If the number is smaller than 5, we round down,
If the number is larger than 5, we round up.
If the number is equal to 5, we still round up.

Henry and his children went into a grocery store and where they sell peaches for $2 each and mangos for $1.25 each. Henry has $20 to spend and must buy no less than 10 peaches and mangos altogether. If Henry decided to buy 4 peaches, determine all possible values for the number of mangos that he could buy. Your answer should be a comma separated list of values. If there are no possible solutions, submit an empty answer.
Answers
Since 4 peaches x 2 =8, you would would only be able to buy 6 mangos since $1.25 x 6 mangos =$7.5 so it would be $7.5+$8=$15.5 and 6 mangos+4 peaches=10 in total. And he would also save $5.00! :)

Answers
Answer: 10 km/ hr
Step-by-step explanation:
In the graph below, Diego's speed at various points during his 10 kilometer race is shown on the y axis while the distance is shown on the x axis.
Looking at the 1km mark on the x axis, Diego's speed on the y-axis is at 10km/ hr and this was the speed he started the race with. After the kilometer mark however, his speed changed and went on to increase to 11km/ hr by the second kilometer mark.

Step-by-step explanation:
We can rewrite the function using vertex form.
f(x) = (x^2 +4x) +10
f(x) = (x^2 +4x +4) +10 -4 . . . . . . . add and subtract (4/2)^2
f(x) = (x +2)^2 +6
Compare to vertex form:
f(x) = (x -h)^2 +k
we see that (h, k) = (-2, 6) . . . . the vertex

The value added and subtracted is the square of half the x-coefficient. Inside parentheses, that value "completes the square". Outside parentheses, that value ensures the overall function remains unchanged.

Answers
Answer:
No
Step-by-step explanation:
7 squared + 10 squared = 149
13 squared = 169
As you can see these two products are not equal. They have to be equal to be a right triangle.
So this triangle is not a right triangle.
Hope that helped you and have a great day!
Answer:
No it is not.
Step-by-step explanation:
Let h = 13, p = 10 and b =7
Using pythagoras theorem,
h² = p² + b²
13² = 10² + 7²
169 = 100 + 49
169 = 149
This is false so the triangle is not a right angled triangle.

Answer:
a) $15,779.70
b) $13,679.70
c) $210.92
Step-by-step explanation:
a) When tax is added, the total cost is ...
total = price × (1 +tax rate)
total = $14,775 × 1.068 = $15,779.70
__
b) The amount financed is the difference between the total cost and the down payment.
financed = total - down35
financed = $15,779.70 -2100 = $13,679.70
__
c) The monthly payment is found using the amortization formula. It can also be found using any of a number of financial calculators, spreadsheets, or apps.
A = P(r/12)/(1 -(1 +r/12)^-n) . . . . annual rate r, n monthly payments, principal P
A = $13,679.70(0.035/12)/(1 -(1 +0.035/12)^-72) ≈ $210.92

The number of action films will be:
= 8/(6+8+1) × 135
= 8/15 × 135
= 72 action films
The number of horror films will be:
= 1/(6+8+1) × 135

Answer:
Step-by-step explanation:
11). 6x + 3y = 9
3(2x + y) = 9
2x + y = 3
y = -2x + 3
Since variables are of single degree therefore, it's a linear function
12). 3y - 2x = -2x - 12
3y - 2x + 2x = -2x - 12 + 2x
3y = -12
y = -4
Since variable y is of single degree therefore its a linear function.
13). 11y + 4x = -8 + 11y
11y + 4x - 11y = -8 + 11y - 11y
4x = -8
x = -2
Linear function.
14). 4x - 3 + 2y = 8x - 9
4x + 2y - 3 - 4x = 8x - 4x - 9
2y - 3 = 4x - 9
2y = 4x - 9 + 3
2y = 4x - 6
y = 2x - 3
Linear function.
