Explanation:
Cosine of an angle is the ratio of the adjacent over the hypotenuse.
For reference angle A, the adjacent leg or closest leg is side AB = 30.
The hypotenuse is always the longest side. The longest side of a right triangle is always opposite the largest angle (the 90 degree angle). So the hypotenuse is AC = 34.
We then say:
cos(angle) = adjacent/hypotenuse
cos(A) = AB/AC
cos(A) = 30/34
cos(A) = (2*15)/(2*17)
cos(A) = 15/17

Answers
1. No. The number of hours are not proportional to her rate.
2. No, because area is squared it would not be proportional to the length of a side.
3. Yes, because he is adding the same anoint every week.
4. Yes, because he is adding the same amount of red for every increase in yellow.

The computer store sells both tablets and laptops. A tablet costs 1500 and a laptop costs 2500 . The store manager wants to sell enough devices to reach the sales goal of 52500 if the store sells 10 tablets, how many laptops the store needs to reach its goal?
Answers
Answer:
1500t and 2500l
52500= 10× 1500 + 2500 l 52500= 15,000 +2500 Hence 15 laptopsAnswer:
15 laptops.
Step-by-step explanation:
You need to find the money earned by selling 10 tablets which is:
1500 x 10 = 15 000
After that, minus the amount of money needed for the goal from the amount of money earned from selling 10 tablets.
52 500 - 15 000 = 37 500
The remaining amount of money is the amount of money you get after finding out how much you make from selling 10 tablets. Use the remaining and divide it with the amount of money needed for each laptop:
37 500 ÷ 2500 = 15

C. 3.2 x 101
O D. 3.1 x 10-2
Answers
Answer:
C. [tex]3.2\times 10^{1}[/tex]
Step-by-step explanation:
[tex]d_r[/tex] = Diameter of a red blood cell = [tex]0.0008\ \text{cm}[/tex]
[tex]d_w[/tex] = Diameter of a whooping cough virus = [tex]2.5\times 10^{-5}\ \text{cm}[/tex]
Ratio of the diameter of the red blood cell to the diameter of the whooping cough virus
[tex]\dfrac{d_r}{d_w}=\dfrac{0.0008}{2.5\times 10^{-5}}=\dfrac{0.0008}{25\times 10^{-6}}=\dfrac{0.0008\times 10^6}{25}\\\Rightarrow \dfrac{d_r}{d_w}=\dfrac{800}{25}\\\Rightarrow \dfrac{d_r}{d_w}=32=3.2\times 10^{1}[/tex]
The required ratio is [tex]3.2\times 10^{1}[/tex].

if triangle ABC is similar to triangle DEF, find the value of x. AB is x and BC is 28. DE is 25 and EF is 20.
Answers
Answer:
x (or AB)=35
Step-by-step explanation:
x/25=28/20
20x=28x25
20x=700
x=35
The length of AB is 35 units
What is Similarity in Triangles?If two triangles have an equal number of corresponding sides and an equal number of corresponding angles, then they are comparable. Similar figures are described as items with the same shape but varying sizes, such as two or more figures.
These three theorems, known as Angle - Angle (AA), Side - Angle - Side (SAS), and Side - Side - Side (SSS),
Given:
ΔABC ~ ΔDEF then the ratio of their corresponding sides are equal
AB/ DE = BC/ EF = AC / DF
So, AB/ DE= BC / EF
x/ 25 = 28 / 20
x/25 = 7/5
x= 5 x 7
x= 35
Hence, the length of AB is 35 units

Renee is creating a rectangular garden in her backyard. The length of the garden is 8 feet. The perimeter of the garden must be at least 30 feet and no more than 32 feet
Answers
Answer: One width of the garden can be 3.8 feet.
Step-by-step explanation: To find the perimeter of the garden, multiply the length by the width. Our width is 3.8 feet and our length is 8 feet.
3.8 x 8 = 30.4 feet.
The perimeter could be 30.4 feet because the garden is at least 30 feet and no more than 32 feet.
So, a width of 3.8 feet would work.

Step-by-step explanation:
20x20=400

400+144=544 sqaure root it and u get 23
The length of the diagonal of Dara’s monitor will be 23.32 inches.
What is the right triangle?A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.
Dara’s computer monitor is 20 inches wide and 12 inches high.
As we can see that the right triangle in the attached figure
Here the length of the diagonal of Dara’s monitor is equal to the hypotenuse.
According to Pythagoras's theorem,
A right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
So 20² + 12² = d²
400 + 144 = d²
d² = 544
d = 23.32
Thus, the length of the diagonal is 23.32 inches.
