Which one is correct? I'm getting told two different things. Find the value of x
Answer:
x ≈ 25.7
Step-by-step explanation:
using the tangent ratio in the right triangle
tan65° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{x}{12}[/tex] ( multiply both sides by 12 )
12 × tan65° = x , then
x ≈ 25.7 ( to the nearest tenth )
There are 32students in categories a and b combined.24are in a and 24 are in b. how many are in both a and b
Answer:
16.
Step-by-step explanation:
48 - 32 = 16
So there are 16 in both category a and category b.
8 will be in category a only, and 8 in category b only.
Total = 8 + 8 +16 = 32.

Find all three angles of the triangle x-5 x+10 x-35
Answer:
See below ~
Step-by-step explanation:
Given : 3 angles of a Δ
(x + 5)°(x + 10)°(x + 15)°Solving :
According to Angle Sum Property of a triangle, the angles of a triangle add up to 180°x + 5 + x + 10 + x + 15 = 1803x + 30 = 180x + 10 = 60x = 50Finding the angles
x + 5 = 50 + 5 = 55°x + 10 = 50 + 10 = 60°x + 15 = 50 + 15 = 65°What is the fully factored form of the expression 45x²y2 + 18x3
Answer:
9x^2(5y^2 + 2x).
Step-by-step explanation:
First find the Greatest Common Factor of the 2 terms.
GCF of 18 and 45 = 9
GCF of x^2 and x^3 = x^2.
The complete GCF is therefore 9x^2.
So, dividing each term by the GCF, we obtain:
9x^2(5y^2 + 2x).

(With explanation, I'm confused because I keep getting x≤−3 when the solution is x≥-3.)
Step-by-step explanation:
To solve the inequality:
4x + 8 ≥ -4
4x ≥ -12
x ≥ -3
If this is what you did then I'm not sure how you ended up getting x ≤ -3. You're not dividing by a negative number so the sign never switches.
Hope this helps
Step-by-step explanation:
−4≤4x+8
Subtraction property of inequality with the value 8.
-12≤4x
Division property of inequality with the value of 4.
The reason the sign stays as less than or greater to is because the sign only switches when the DIVISOR is negative, not the dividend.

15 men produce 500 watches in 15 working days. How long would it take 45 men to produce 500
watches?
Answer:
It would take 45 men 5 days to make 500 watches.
Explanation.
for 15 men it takes 15 days.
but if you have 45 men. that is 3x the amount of men.
they will be able to make watches 3 times faster.
just believe me its the right answer.
Please Vote Me Brainliest. Thank You.
(Assuming every single man has the same working rate.)
Solution 1 :
If there is 45 men working, there will be 45 : 15 = 3 times as much men.
So, the amount of time taken will be reduced by 3 times.
=> It will take 15 : 3 = 5 days for 45 men to produce 500 watches.
Solution 2 :
15 men produce 500 watches in 15 days -> If there is only 1 man, it will take 15 x 15 = 225 (days).
If there is 45 men, the amount of time will reduce by 45 times.
So, it will take 225 : 45 = 5 days for 45 men to produce 500 watches.
What is the area, in square units, of a trapezoid bounded by the lines $y = x$, $y = 10$, $y = 5$ and the $y$-axis? express your answer as a decimal to the nearest tenth
The area of a trapezoid is bounded by the lines y = x, y = 10, y = 5, and the y− axis is 37.5 square units.
What is the area of the trapezium?A trapezium is a quadrilateral having two opposite sides parallel.
The area of a trapezium is equal to;
[tex]\rm Area =\dfrac{1}{2} \times \text{Distance between the parallel sides} \times \text{Sum of the parallel sides}[/tex]
The trapezoid is bounded by the lines y = x, y = 10, y = 5, and the y− axis.
The vertices are at (0,10), (10,10),(5,5) and (0,5)
You need to find the area of the rectangle (0,10) (10,5) (0,5) and (5,5)
The lengths are 5, 5,5,5.
The area of the legs is = 5 × 5 =25
The area is;
[tex]\rm Area =\dfrac{1}{2} \times \text{Distance between the parallel sides} \times \text{Sum of the parallel sides}\\\\Area =\dfrac{1}{2} \times 5 \times 5\\\\Area =12.5[/tex]
And the right triangle (10,5),(5,5), and (10,10) the right angle is at (10,5)
the two legs are lengths 5 and 5
so together they are 25 +12.5=37.5 square units.
Hence, the area of a trapezoid is bounded by the lines y = x, y = 10, y = 5, and the y− axis is 37.5 square units.
