The largest number that should be added to -11 to obtain a sum less than -5 is 5.
Explanation:To find the largest number that should be added to –11 to get a sum less than –5 you need to relate these two numbers. If you add a number to -11 that brings you exactly to -5, it means you're adding 6 (because -11 + 6 = -5). However, you need the sum to be less than -5. So the largest number you can add to -11 to get a number less than -5 would be 5 (because -11 + 5 = -6, and -6 is less than -5). So, the answer is 5.

In triangle ABC, angle C is a right angle. Find the value of the trig function indicated. Find sin A if b = 8, c = 17, a = 15
Answer:
15/17
Step-by-step explanation:
sin A = side opposite A/ hypotenuse
= a/ c
=15/17
We use the definition of sine, which leads to sin A = a/c = 15/17, giving sin A = 0.8824.
To find sin A, we can use the definition of sine in a right-angled triangle, which is the ratio of the length of the opposite side to the length of the hypotenuse.
In this case, sin A = opposite/hypotenuse = a/c = 15/17. Therefore, sin A = 0.8824, rounded to four decimal places.

8. Which is the probability that two 1-6 number cubes land on an even number?
A 0.75
B 0.50
C 0.25
D 0.10
The probability that two 1-6 number cubes both land on an even number is calculated by multiplying the individual probabilities for each cube (1/2 x 1/2), resulting in a final probability of 0.25, or answer 'C. 0.25.'
To determine the probability that two 1-6 number cubes land on an even number, we first recognize that there are three even numbers on each cube (2, 4, and 6), and thus three favorable outcomes out of six possible outcomes for each individual number cube roll. To calculate the probability of two independent events both occurring (in this case, both number cubes landing on an even number), we multiply the probabilities of each event.
The probability for one cube is 3/6, or 1/2. Therefore, for two cubes, the probability is (1/2) x (1/2) = 1/4. Expressed as a decimal, 1/4 is equivalent to 0.25.
The correct answer to the question is 'C. 0.25.'

Given a polynomial f(x), if (x - 1) is a factor, what else must be true?
A. f(0) = 1
b. f(1) = 0
c. f(-1) = 0
d. (0) = -1
Answer: Option b
[tex]f (1) = 0[/tex]
Step-by-step explanation:
For a function of the form
[tex]f (x) = ax ^ n + bx ^ {n-1} + ... + c[/tex]
Where n is the main exponent of the polynomial and a, b c are the coefficients of the variables then this polynomial can be written based on its factors as
[tex]f (x) = a (x-h) (x-k) (x-s)...[/tex]
Where [tex]x = h[/tex], [tex]x = k[/tex], [tex]x = s[/tex], ... are the points where [tex]f(x) = 0[/tex]
Therefore if for this case we know that
[tex](x-1)[/tex] is a factor of a polynomial function [tex]f (x)[/tex] then it is fulfilled that
[tex]f (1) = 0[/tex]

21x - 14 = 98; x = 5
Reset
Submit
Answer:
The correct answer is: 21x + 14 = 98; x = 4.
Step-by-step explanation:
She needs to type the notes she recorded in her 98-page workbook. If whe types x hours at a rate of 21 pages per hour, and 14 pages are already done. Then the equation is:
21x + 14 = 98;
Now, the number of hours she will take to complete the task can be found by solving for 'x':
21x = 98 - 14
21x = 84
x = 4.
Therefore, the correct option is: 21x + 14 = 98; x = 4.
Answer:
21x + 14 = 98; x = 4
Step-by-step explanation:
Camille has already typed notes from the first 14 pages of her workbook, and she types for x hours at a rate of 21 pages per hour. An expression for the one side of the equation needs to represent the total number of pages she has typed in terms of x. The number of pages Camille has typed after x hours is represented by the expression 21x + 14.
The workbook has a total of 98 pages. Thus, the other side of the equation which represents the number of pages Camille has typed after x hours is 98.
Hence, the equation that represents the number of pages she has typed after x hours is 21x + 14 = 98.
Solve the equation to determine how many hours it will take Camille to complete the task.
So, x = 4. Therefore, it takes Camille 4 hours to complete the task.

A grid shows the positions of a subway stop and your house. The subway stop is located at (-5,2) and your house is located at (-9,9). what is the distance, to the nearest unit, between your house and the subway stop?
Answer:
8
Step-by-step explanation:
Calculate the distance (d) using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 5, 2) and (x₂, y₂ ) = (- 9, 9)
d = [tex]\sqrt{(-9+5)^2+(9-2)^2}[/tex]
= [tex]\sqrt{(-4)^2+7^2}[/tex]
= [tex]\sqrt{16+49}[/tex] = [tex]\sqrt{65}[/tex] ≈ 8 ( nearest unit )
Answer: The required distance between my house and the subway stop is 8 units.
Step-by-step explanation: Given that a grid shows the positions of a subway stop and my house. The subway stop is located at (-5,2) and my house is located at (-9,9).
We are to find the distance, to the nearest unit, between my house and the subway stop.
We will be using the following formula :
Distance formula : The distance between the points (a, b) and (c, d) is given by
[tex]D=\sqrt{(c-a)^2+(d-b)^2}.[/tex]
Therefore, the distance between the points (-5, 2) and (-9, 9) is given by
[tex]D\\\\=\sqrt{(-9-(-5))^2+(9-2)^2}\\\\=\sqrt{(-9+5)^2+7^2}\\\\=\sqrt{4^2+49}\\\\=\sqrt{16+49}\\\\=\sqrt{65}\\\\=8.06.[/tex]
Rounding to the nearest units, we get
D = 8 units.
Thus, the required distance between my house and the subway stop is 8 units.
A family travels, by plane, five hundred miles from their city to a beach town. Then they take a taxi from the airport to the hotel at the beach. When they ask the driver how far the airport is from the hotel, he tells them twenty kilometers. What is the approximate total distance, in miles, the family traveled? Recall that 1 kilometer is about 0.62 miles.
Answer:
512.4 miles
Step-by-step explanation:
The distance from city to beach town = 500 miles
Distance from airport to hotel = 20 kilometers
In order to find the total distance we have to convert the kilometers in miles to bring both quantities in same unit
So,
1 kilometer = 0.62 miles
20 kilometers = 20*0.62 =12.4 miles
As both the quantities are in same unit,
The total distance = Distance from city to beach town + distance from airport to hotel
= 500 + 12.4
= 512.4 miles
Hence, total distance covered by them is 512.4 miles ..
What is the measure of <B 98 108 118 128
Answer:
Step-by-step explanation:
By observation, you can see that the irregular polygon can be split into 4 triangles (see attached image). We know that the sum of the internal angles of 1 triangle is always 180 degrees. Hence the sum of all the internal angles of the polygon is,
180 degrees x 4 triangles = 720 degrees.
Therefore Angle B,
= sum of internal angles - sum of all other known angles
= 720 - (133 +102+117+90+170)
= 108 degrees.
The measure of angle B is 108 degrees.
What is angle sum property?
Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.
We can divide the given polygon in split into 4 triangles.
Using, angle sum property,
The sum of the internal angles of triangle is always 180 degrees.
Hence the sum of all the internal angles of the polygon is,
=180 x 4 triangles
= 720 degrees.
Now, angle B
= 720 - (133 +102+117+90+170)
=720 -612
= 108 degrees.
Hence, angle B is 108 degrees.

Factor the trinomial below x^2+7x-30
Answer:
(x + 10)(x - 7)
Step-by-step explanation:
It is 3 and 10 in some order. The difference is 7 and it is plus, so the larger number is +10 and the smaller one - 3
(x + 10)(x - 3) should be the answer
10x - 3x = 7x
The trinomial [tex]x^2+7x-30[/tex] can be factored into (x+10)(x-3) by finding two numbers that multiply to -30 and add to 7.
To factor the trinomial [tex]x^2+7x-30[/tex] we are looking for two numbers that multiply to -30 (the constant term) and add up to +7 (the coefficient of the linear term).
These two numbers are +10 and -3, as -
10 * -3 = -30 and
10 + (-3) = 7.
So, we can rewrite the trinomial as (x+10)(x-3), which are the factors of the lowest possible order.
