Answer:
5 days 6hours
Step-by-step explanation:
Given data
total amount of flour=42kg
number of kg used per day=8kg
Since we are expected to know when she will need more, we need to divide the total flour by the daily usage, to know when the flour we be exhausted
divide 42 by 8 we have
42/8=5.25------0.25 days to hours is 6hours
So it will take 5 days 6hours
PLEASE ANSWER ASAP!!! Find the discriminant of the following function. Then identify how many solutions and the type of solutions there will be.
f(x)=3x^2-7x+5
Answer:
No solutionStep-by-step explanation:
Given function
f(x) = 3x^2 - 7x + 5Zeros of the function
3x^2 - 7x + 5 = 0D = √(b^2 - 4ac) = √(49 - 60) = √-11There is no solution as the discriminant is negative
It means the graph of this function doesn't intersect with x axis and is above it
Every rope has a safe working load. A rope should not be used to lift a weight greater than its safe working load. The table shows the safe working loads $S$ (in pounds) for ropes with circumference $C$ (in inches). Write an equation for the safe working load for a rope. Find the safe working load for a rope that has a circumference of 10 inches.
Answer:
the equation is:
f(x) = 180x²
the maximum working load for a 10 inch rope = 180 · 10² = 18,000 pounds

Step-by-step explanation:
The measure of the angle ∠A will be 50°. The correct option is A.
What are lines and angles?Straight lines with little depth or width are present. You will learn about a number of lines, including transversal, intersecting, and perpendicular lines. A figure called an angle is one in which two rays originate from the same point. In this area, you could also encounter contrasting and related viewpoints.
Given that the two angles are 85 and 145. The internal angles will be calculated as,
180 - 85 = 95
180 - 145 = 35
The angle A will be calculated as below,
∠A = 180 - 35 - 95
∠A = 50°

Step-by-step explanation:
The total length of three boards is 7/8 of a yard. The length of two of the boards are 1/4 of a yard and 3/16 of a yard. What is the length of the third board.
Answer:
7/16 of a yard
Step-by-step explanation:
Let's put the boards to the same denominator so it's easier.
Let's go with a denominator of 16
1/4= 4/16
7/8= 14/16
3/16 stays the same.
So, 4/16+3/16+x=14/16
7/16+x=14/16
x=7/16 of a yard, the length of the 3rd board.
How to find a rational function given 2 vertical asymptotes and an X intercept?
It’s question 20 by the way
Answer:
[tex]\frac{x-4}{(x+3)(x-5)}[/tex]
Step-by-step explanation:
Since the rational function has vertical asymptotes at -3, and 5, the denominator must equal 0 when x is -3 or 5. Therefore, the denominator must be:
(x+3)(x-5)
Now, to make the x-intercept at (4, 0), the numerator must be equal to 0 when x is 4. Therefore, the numerator must be:
x-4
Therefore, that rational function is:
[tex]\frac{x-4}{(x+3)(x-5_}[/tex]

Television sizes are determined by the length of their diagonal measure. Michael just bought a new television. The height of the television is 37 inches and the length is 71 inches.
Using the Pythagorean Theorem, what is the size of Michael’s new television? Round your answer to the nearest whole inch (whole number).
Part A: What parts of the right triangle have you been given? Are you looking for a leg or the hypotenuse?
Part B: Set-up your equation by substituting the correct numbers into the Pythagorean Theorem formula.
Part C: Solve for the missing length rounded to the nearest whole number. Remember to show ALL work for each step.
Part D: What is the size of the television rounded to the nearest whole inch (whole number)? REMEMBER: We’re looking for the length of the diagonal, as that is the measurement used to determine TV Sizes.
Answer:
see below
Step-by-step explanation:
given: size of television is height = 37 in, length = 71 in.
A. using Pythagorean theorem:
parts given are legs which is the sides
looking for the hypotenuse.
B. formula:
a² + b² = c² or H² + L² = D²
where H = height = 37
L = length = 71
D = diagonal (which is req'd)
C. D² = 37² + 71²
D = [tex]\sqrt{1369+ 5041}[/tex]
D = [tex]\sqrt{6410}[/tex]
D = 80 in (missing length)
D. size of television:
37 x 71 in
Diagonal is 80 in

What are some ways we can tell that 7x + 2 is not equivalent to 9x?
Answer:
To determine if two fractions are equivalent, cross multiply. To cross multiply, you multiple the numerator of the first fraction by the denominator of the second. Then you multiply the denominator of the first fraction by the numerator of the second. If the two numbers are equal, the fractions are equivalent

You are playing a video game. For each diamond you collect, you earn 100 points. You also earn 75 bonus points by completing the level in less than 2 minutes. You need to earn more than 1575 points to continue on to the next level. Write and solve an inequality that represents the numbers d of diamonds you must collect in less than 2 minutes to advance to the next level.
Answer:
The data that we have is:
For each diamond, you earn 100 points.
If you complete the level in less than 2 minutes, you earn a bonus of 75 points.
You want to earn more than 1575 points.
Now, assuming that you want to write and solve n inequality that represents the numbers d of diamonds you must collect in less than 2 minutes to advance to the next level.
Because you end in less than 2 minutes, then you have the bonus of 75 points.
Then the number of points as a function of d, the number of diamonds, is:
P(d) = 100*d + 75
And you want that:
P(d) > 1575
100*d + 75 > 1575
Now we can solve this for d.
100d > 1575 - 75
100d > 1500
d > 1500/100
d > 15
You must collect more than 15 diamonds.
