If side x has a length of 15 cm and side y has a length of 4 cm, then which value below could be the length of side z?
A.
20 cm
B.
21 cm
C.
17 cm
D.
10 cm
Given:
In a triangle, side x has a length of 15 cm and side y has a length of 4 cm.
To find:
The possible value of side z.
Solution:
In a triangle, the sum of two smaller sides must be greater than the largest side otherwise the triangle is not possible.
Case I: Let x be the largest side, then
[tex]y+z>x[/tex]
[tex]4+z>15[/tex]
[tex]z>15-4[/tex]
[tex]z>11[/tex] ...(i)
It is clear that [tex]y<x[/tex]. So, y cannot be a largest side.
Case II: Let z be the largest side, then
[tex]x+y>z[/tex]
[tex]15+4>z[/tex]
[tex]19>z[/tex] ...(ii)
From (i) and (ii), we get
[tex]11<z<19[/tex]
It means the value of z lies between 11 and 19.
From the given options, only 17 is the value which lies between 11 and 19. So, the possible length of side z is 17 cm.
Therefore, the correct option is C.
After 4 days, a bookstore has 140 copies of a new title still on hand. After 9 days, the bookstore has 50 copies still on hand. Model this situation by writing an equation of the form c(t)=mt+b where c is the number of copies still on hand after t days of being available
Answer:
[tex]c(t) =-18t +212[/tex]
Step-by-step explanation:
Given
[tex](t_1,c_1) = (4,140)[/tex]
[tex](t_2,c_2) = (9,50)[/tex]
Required
Determine the equation
First, we calculate the slope (m)
[tex]m = \frac{c_2 - c_1}{t_2 - t_1}[/tex]
[tex]m = \frac{50 - 140}{9-4}[/tex]
[tex]m = \frac{-90}{5}[/tex]
[tex]m = -18[/tex]
The equation is then calculated as:
[tex]c =m(t - t_1) + c_1[/tex]
[tex]c =-18*(t - 4) + 140[/tex]
[tex]c =-18t +72 + 140[/tex]
[tex]c =-18t +212[/tex]
Hence, the function is:
[tex]c(t) =-18t +212[/tex]
Pete and Marsha are going to buy a swimming pool. Mike wants a rectangular one that is 18 feet wide, 20 feet long, and 6 feet deep, and Marsha wants a circle shaped pool that is 20 feet across and 6 feet deep. They decide to buy the pool that cost less to fill. If the price of water is 25 cents per cubic foot, which pool do they buy and how much does it cost?
Answer:
The pool that they buy is the circular pool which Marsha wants
The cost of the circular pool is $471.25
Step-by-step explanation:
The parameters of the swimming pools which each of Pete and Marsha wants to buy is given as follows;
The dimensions of the pool Pete wants = 18 feet wide, 20 feet long and 6 feet deep
The dimensions of the circle shaped pool Marsha wants = 20 feet across and 6 feet deep
The price of water, P = 25 cents per cubic foot
The pool they decide to buy = The pool that costs less to fill
The volume of water to fill the pool Pete wants, V₁ = 18 ft. × 20 ft. × 6 ft. = 2,160 ft.³
The cost of filling the pool Pete wants, C₁ = V₁ × P
∴ C₁ = 2,160 ft.³ × 25cents/ft.³ = 54,000 cents = 540 Dollars
The volume of water to fill the pool Marsha wants, V₂ = π·(20 ft.)²/4 × 6 ft. ≈ 1,884.96 ft.³
The cost of filling the pool Marsha wants, C₁ = V₁ × P
∴ C₁ ≈ 1,884.96 ft.³ × 25 cents/ft.³ ≈ 47,124 cents = 471.24 Dollars
The pool that they buy is the circular pool that Marsha wants and it costs $471.24 to fill

Answer:
for the first answer your answer was correct, it was the second answer that was wrong. So the first answer is 2 3/4. The second answer would be 81 centimeters because it grew that much.
Step-by-step explanation:
To find the first answer add the starting height and ending height. To find how much it grew convert the total ending height of the tree to cm by multiply by 100, so 275. Then subtract 356 by 275 because you are finding out how much it grew. Take away 275 from 356 and you get 81
A ball is thrown straight up with initial velocity of 64 ft./s. The height of the ball t seconds after it is thrown is given by the formula s(t)=64t-16t^2
Answer:
64 feet
Step-by-step explanation:
Complete question
A ball is thrown straight up with initial velocity of 64 ft./s. The height of the ball t seconds after it is thrown is given by the formula s(t)=64t-16t^2. Find the maximum height reached by the ball.
At maximum height, the velocity of the ball is zero, i.e ds/dt =0
ds/dt = 64 - 32t
64 - 32t = 0
32t = 64
t = 64/32
t = 2secs
Substitute t = 2secs into the given equation;
Recall that s(t)=64t-16t^2
s(2) = 64(2) - 16(2)^2
s(2) = 128 - 16(4)
s(2) = 128 - 64
s(2) = 64 ft
Hence the maximum height reached by the ball is 64 feet
5 Mario has $660 in his savings account earning 2.5% interest yearly. How much interest will he earn in 2 years?
Im terrible at word problems smh
Answer:
$33
Step-by-step explanation:
You do $660 • 0.025
You have to bring the decimal two places to the left for finding the decimal point.
So you'd get 16.5.
But there's two years. So times it by two.
So it's 33.

Suppose that 29\%29%29, percent of undergraduates at a large university are involved in a campus organization. The administration plans to take an SRS of 100100100 undergraduates from the population of over 20{,}00020,00020, comma, 000 undergraduate students at the school to see what proportion of students sampled are involved in a campus organization.
Answer:
μ p ^ =0.29
σ p ^ = Square root[ ( (0.29)(0.71) )/100 ]
Step-by-step explanation:
The mean of the sampling distribution of a sample proportion is equal to the population proportion.
μ p ^ =p
The population proportion reported is 29%, so p=0.29p.
\mu_{\hat p}=p=0.29μ
μ p ^ = 0.29
Since σ p hat = sqare root [ ( p(1-p) )/ n]
After subsitution we get σ p ^ = Square root[ ( (0.29)(0.71) )/100 ]

a man makes a profit 15% by selling an article for rs.250. for what amount should he sell it to make profit of 38%
Answer:
$300
Step-by-step explanation:
original price = $250
the profit= 15%
ok now let the cost price of article be ₹ x
x + 15% of x = 250
1.15x = 250 => 115x ÷ 100 = 250
115x = 25000 => x = 25000 ÷ 115
x = 5000/ 23
cost price of article = ₹5000/ 23
required profit = 38%
= 38% of 5000/ 23 = 0.38 × 5000/ 23
= 1900/ 23
the required will be selling price to gain about 38%
= cost price + required profit which is
= (5000/ 23) + (1900/ 23)))
= 6900/ 23 = $300
Answer: now its required selling price = $300

What is a trigonometric function?The fundamental 6 functions of trigonometry have a range of numbers as their result and a domain input value that is the angle of a right triangle.
The trigonometric function is only valid for the right angle triangle and it is 6 functions which are given as sin cos tan cosec sec cot.
The trigonometric functions found in the four quadrants, as well as their graphs, domains, and differentiation and integration, will all be understood.
The trigonometric function is very good and useful in real-life problems related to the right-angle triangle.
Given that in triangle Y is 90° since in any triangle sum of all three angles will be 180° so remaining angle Z and Y will be total of 90° hence these will be complementary.
In right angle triangle sinX = cosZ because the perpendicular for X act like a base for Y.

Give step by step instructions and the final answer on how to find the volume of a right square pyramid who has a slant height of 5 inches and the length of the base is 4 inches.
To earn full points you must :
- Show each step of your work
- Keep it organized and easy to read
- Give a brief explanation of why you perform each step
- give the correct final answer
Answer:
Below.
Step-by-step explanation:
First find the perpendicular height of the pyramid.
The median of one of the faces, the height and and half the length of the square base make a right triangle with base 2 and hypotenuse 5, so using the Pythagoras theorem:
5^2 = 2^2 + h^2
h^2 = 5^2 - 2^2 = 21
h = √21 inches.
The volume of the pyramid V = 1/3 * h * area of the base, so
V = 1/3 * 4^2 * √21
= 24.44 in^3 to nearest hundredth.
The volume of a right square pyramid will be (16√21) / 3 cubic units.
What is the volume of the pyramid?Let h be the height of the pyramid, l be the slant height and A be the base area of the pyramid.
Then the volume of the pyramid will be
Volume = (1/3) × A × h
The slant height is given as.
l² = (half of side)² + h²
A right square pyramid has a slant height of 5 inches and the length of the base is 4 inches.
Then the height of the pyramid will be
5² = (4/2)² + h²
h² = 25 - 4
h = √21 inches
Then the volume of a right square pyramid will be
Volume = (1/3) × 4 × 4 × √21
Volume = (16√21) / 3
Thus, the volume of a right square pyramid will be (16√21) / 3 cubic units.
More about the volume of the pyramid link is given below.

Bilal and Charlie have some sweets. Bilal has 4 times as many sweets as Charlie. Bilal gives Charlie 15 of his sweets and now they have the same amount. How many sweets do they have altogether?
Answer:
50
Step-by-step explanation:
The computation of the number of sweets they do have altogether is as follows:
Let us assume Charlie sweets be x
So bilal sweets is 4x
Now Bilal gives Charlie 15 of his sweets due to which they must have the same amount
4x - 15 = x + 15
4x -x = 15 + 15
3x = 30
x = 10 = Charlie sweets
Bilal sweets = 4x = 4(10) = 40
So the total no of sweets held by them is 50
