A farmer has harvested 60% of his crops.
If he has harvested 72 acres, how many
acres does the farmer have in all?
can anybody solve this for me
Step-by-step explanation:
Square root of 25 can be +5 or -5
Square root of 16 can be +4 or -4.
As -5 can be square root of 25 and +4 can be a root of 16 , -5 < +4 . That's why square root of 25 could be less than square root of 16.

Merlin wants to make more money selling fake beards this month than
he did last month. All black beards in his shop cost the same amount of
money, and all red beards in his shop cost $25.
Let B represent the number of black beards and R represent the
number of red beards that Merlin can sell to make more money than he
made last month.
20B+25R>350
According to the inequality, how much money did Merlin make last
month, and how much does each black beard cost?
Can Merlin achieve his goal by selling 6 black beards and 8 red
beards? explain why.
Answer:
According to the inequality, how much money did Merlin make last month more than? -> 350 dollars
Can Merlin achieve his goal by selling 6 black beards and 8 red
beards? explain why.
Yes, black beard sum will total up to $120 and red beard sum will total up to $200, $120+$200 = $320
$320 < $350

8
How do you rename this as a mixed number
Answer:
2 3/8
Step-by-step explanation:
Answer:
Assuming you meant 19/8, the answer would be 2 and 3/8
Step-by-step explanation:
How many times does 8 go into 19? Twice, plus you will have 3 leftover since 8 x 2 is only 16 and not 19. That 2 stays a 2 and the left over 3 is 3/8, so your answer is 2 + 3/8

7v=4v-32 how do i solve this
Answer:
v = [tex]-\frac{32}{3}[/tex]
Step-by-step explanation:
7v = 4v - 32
7v - 4v = -32
3v = -32
v = [tex]-\frac{32}{3}[/tex]
Answer:
10.68
Step-by-step explanation:
7v=4v-32
-4v -4v
----------------
3v=-32
v=10.67
So then you'd plug that into the thing:
7(10.67)=4(10.67)-32
74.69=42.68-32

If a(x)=3x+1 and b(x)= x-4, what is the domain of ..
Step-by-step explanation:
For sqrt(x - 4) to be defined, x >= 4.
For a(x) >= 4, 3x + 1 >= 4, x >= 1.
Hence the domain of the composite function is the 3rd from the top.

1. If -17(x - 2) = 16 + x, what is the value of x?
(A). -2
(B). -1
(C). O
(D). 1
(E). 2
Answer:
(D). 1
Step-by-step explanation:
-17(x - 2) = 16 + x
-17 × x - (-17) × (2) = 16 + x
-17x + 34 = 16 + x
-17x - x = 16 - 34
-18x = - 18
18x = 18
x = 18/18
x = 1
Thus, The value of x is 1

Alice went straight from the library to school, so we need to find the hypotenuse of the triangle. Use the Pythagorean theorem (a^2 + b^2 = c^2) and substitute 10 for a and 24 for b to get 100 + 576 = c^2 or 676 = c^2
Take the square root of 676 to get 26 for Alice's distance.

Answer:
Option D
Step-by-step explanation:
We have to find the value of the composite function (h o k)(2).
Since, (h o k)(x) = h[k(x)]
(h o k)(2) = h[k(2)]
From the picture attached,
At x = 2
k(2) = (-2)
Therefore, h[k(2)] = h(-2)
Since, h(x) = [tex]\frac{3}{x+1}[/tex]
Therefore, h(-2) = [tex]\frac{3}{-2+1}[/tex]
= -3
(h o k)(2) = -3 is the answer.
Option (D) is the correct option.
please show the working and answer. you can take a picture for the working.
Answer:
(a) The area of the triangle is approximately 39.0223 cm²
(b) ∠SQR is approximately 55.582°
Step-by-step explanation:
(a) By sin rule, we have;
SQ/(sin(∠SPQ)) = PQ/(sin(∠PSQ)), which gives;
5.4/(sin(52°)) = 6.8/(sin(∠PSQ))
∴ (sin(∠PSQ)) = (6.8/5.4) × (sin(52°)) ≈ 0.9923
∠PSQ = sin⁻¹(0.9923) ≈ 82.88976°
Similarly, we have;
5.4/(sin(52°)) = SP/(sin(180 - 52 - 82.88976))
Where, 180 - 52 - 82.88976 = ∠PQS = 45.11024
SP = 5.4/(sin(52°))×(sin(180 - 52 - 82.88976)) ≈ 4.8549
Given that RS : SP = 2 : 1, we have;
RS = 2 × SP = 2 × 4.8549 ≈ 9.7098
We have by cosine rule, [tex]\overline {RQ}[/tex]² = [tex]\overline {SQ}[/tex]² + [tex]\overline {SR}[/tex]² - 2 × [tex]\overline {SQ}[/tex] × [tex]\overline {SR}[/tex] × cos(∠QSR)
∠QSR and ∠PSQ are supplementary angles, therefore;
∠QSR = 180° - ∠PSQ = 180° - 82.88976° = 97.11024°
∠QSR = 97.11024°
Therefore;
[tex]\overline {RQ}[/tex]² = 5.4² + 9.7098² - 2 × 5.4×9.7098× cos(97.11024)
[tex]\overline {RQ}[/tex]² ≈ 136.42
[tex]\overline {RQ}[/tex] = √(136.42) ≈ 11.6799
The area of the triangle = 1/2 ×[tex]\overline {PQ}[/tex] × [tex]\overline {PR}[/tex] × sin(∠SPQ)
By substituting the values, we have;
1/2 ×[tex]\overline {PQ}[/tex] × [tex]\overline {PR}[/tex] × sin(∠SPQ)
1/2 × 6.8 × (4.8549 + 9.7098) × sin(52°) ≈ 39.0223 cm²
The area of the triangle ≈ 39.0223 cm²
(b) By sin rule, we have;
[tex]\overline {RS}[/tex]/(sin(∠SQR)) = [tex]\overline {RQ}[/tex]/(sin(∠QSR))
By substituting, we have;
9.7098/(sin(∠SQR)) = 11.6799/(sin(97.11024))
sin(∠SQR) = 9.7098/(11.6799/(sin(97.11024))) ≈ 0.82493
∠SQR = sin⁻¹(0.82493) ≈ 55.582°.
