Step-by-step explanation:
Let
Width of the painting = x inches, then
Length of the painting [tex]=1\dfrac{1}{4}x[/tex] inches
The area of the painting:
[tex]A=\\ \\=\text{Width}\times \text{Length}=\\ \\=x\times 1\dfrac{1}{4}x=\\ \\=\dfrac{5}{4}x^2\ in^2[/tex]
Hence,
[tex]\dfrac{5}{4}x^2=180\\ \\x^2=\dfrac{4}{5}\times 180=4\times 36=144\\ \\x=12\ inches\\ \\\text{Width}=12\ inches\\ \\\text{Length}=\dfrac{5}{4}\times 12=15\ inches[/tex]

y= 28√3
Step-by-step explanation:
Please see attached picture for full solution.
(tan30° and cos30° are special angles so there's an exact value to it in which we can memorise.)
In this case, by Pythagoras's Theorem, you should ensure that:
[tex] {y}^{2} = 42^{2} + {x}^{2} [/tex]
✓ Let's check:
[tex]{y}^{2} = (28 \sqrt{3} )^{2} \\ y^{2} = 2352 \\ {x}^{2} + {42}^{2} = ( 14\sqrt{3})^{2} + 1764 = 2352[/tex]
This satisfies Pythagoras' Theorem :)
For this kind of questions, first label the adjacent side, opposite side and the hypotenuse side of the triangle.
Cosine angle= adjacent/ hypotenuse
Sine angle= opposite/ hypotenuse
tangent angle= opposite/ adjacent
Then substitute the known side and angle to find the unknown side.

0.25 =
0.25 × 100/100 =
0.25 × 100% =
(0.25 × 100)% =

(25 ÷ 100) × 450 =
(25 × 450) ÷ 100 =
11,250 ÷ 100 =
112.5
Answer:
112.5
Step-by-step explanation:
First you would divide 450÷100=4.5. Then you would multiply 4.5×25=112.5.
this would give you 25% of 450
400÷100=4.5

6. Find the value of x.
19x - 36
6x + 31
Answers
Final answer:
To find the value of x, set the expressions equal to each other and solve for x.
Explanation:
To find the value of x in the given equation, we need to set the two expressions equal to each other and solve for x. So, we have:
19x - 36 = 6x + 31
Subtracting 6x from both sides, we get:
13x - 36 = 31
Adding 36 to both sides, we get:
13x = 67
Dividing both sides by 13, we get:
x = 67/13
So the value of x is approximately 5.15.

The ratio of men to women working for a company is 4 to 7. If there are 105 women working for the company, what is the total number of employees? (Help please)
Answers
Answer:
165 people
Step-by-step explanation:
If there are 105 woman then there are going to be 60 men because 105/7=14, so you multiply 4*15 and get 60. 60 + 105= 165. So the total employees will be 165.
The total number of employees is the sum of men and women, which is 105 (women) + 60 (men) = 165 employees.
To find the total number of employees, calculate the number of men from the given ratio 4:7 and the number of women (105), and then add the number of men to the number of women to get the total.
The question is about finding the total number of employees in a company given the ratio of men to women and the number of women.
Let's use the provided ratio of men to women, which is 4 to 7, to calculate the number of men.
Since there are 105 women, and the ratio dictates that for every 7 women there are 4 men, we divide 105 by 7 to find the number of units that represent women, which is 15.
We then multiply this by 4 (the number of men) to find the number of men, which is 60.
105 + 60 = 165

Answer:
6 cups
Step-by-step explanation:
did the math
For two cups of boiling water, 6 cups of sugar would be needed
The first step is to determine how many cups of sugar that would be needed for one cup of boiling water
The number of cups of sugar needed for a cup of boiling water = cups of sugar / cups of boiling water
2 ÷ [tex]\frac{2}{3}[/tex]
2 x [tex]\frac{3}{2}[/tex] = 3 cups
The second step is to determine the number of cups of sugar that would be needed with two cups of boiling water
Cups of sugar needed for 2 cups of water = cups of sugar needed for one cups of boiling water x 2
3 cups x 2 cups = 6 cups
In order to determine the cups of sugar needed for two cups of boiling water, first determine the number of cups of sugar needed for a cup of boiling water. Use the figure determined to find the cups of sugar needed for 2 cups of water

The equations used to find the length of leg of triangle are:

Solution:
From given,
Area of right triangle = 24 square feet
Also from given figure in question (attached below )
base = x and height = x + 2
The area of triangle is given by formula:
[tex]Area = \frac{1}{2} \times base \times height[/tex]
Substituting the values we get,
[tex]24 = \frac{1}{2} \times x \times (x+2)\\\\24 = 0.5x(x + 2)\\\\48 = x(x+2)\\\\x^2 + 2x - 48 = 0\\\\[/tex]
Also, the above equation can be written as,
