Answer:
80 days
Step-by-step explanation:
8 divide by 0.1 = 80
Answer:
80 days
Step-by-step explanation:
We know that your cat eats 0.1 ounces of tuna per day, we need to find out how many days you can feed 8 ounces of tuna fish.
We need to keep in mind that 0.1 is a very tiny portion, and to get reach 1, your cat would have to eat 0.1 ounce everyday for 10 days, because 0.1 * 10 = 1
Now since we know it takes 10 days to reach 1 ounce, we need to see how many times it'll take for 10 days to reach 8 ounces.
10 * 8 = 80
Therefore it'll take 80 days to reach 8 ounces.
Work out the lengths of sides a and b.
Give your answers to 1 decimal place.
45 cm
20 cm
a
5 cm
b
3 cm
They are right triangles so you can use the Pythagorean theorem.
A = sqrt(5^2+3^2)
A = sqrt(25+9)
A = sqrt(34) (exact answer)
As a decimal it would be: 5.8
B = 45 = sqrt( 20^2 + b^2)
B^2 = 45^2-20^2
B^2 = 2025-400
B^2 = 1625
B = sqrt(1625)
B = 5sqrt(65) exact answer
As a decimal : 40.3
Answer:
Side length A is 5.8cm
Side length B is 40.3cm
Step-by-step explanation:
To find A:
5^2+3^2=34
square root of 34= 5.83...
round to 5.8
To find B:
45^2-20^2= 1625
square root of 1625= 40.3112...
round to 40.3

PLEASE HELP ASAP!!!! I CAN GIVE BRINLIEST!!!!A bicycle manufacturing company makes a particular type of bike. Each child bike requires 4 hours to build and 4 hours to test. Each adult bike requires 6 hours to build and 4 hours to test. With the number of workers, the company is able to have up to 120 hours of building time and 100 hours of testing time for a week. If c represents child bikes and a represents adult bikes, can the company build 20 child bikes and 6 adult bikes in a week. (2 points)
A) No, because the bike order does not meet the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100
B) No, because the bike order does not meet the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100
C) Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100
D) Yes, because the bike order meets the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100

Answer:
2.[tex]-2m^4-6m^2+4m+9[/tex]
3.[tex]-2m^4-6m^2-4m+9[/tex]
Step-by-step explanation:
In general we can write a polynomial in standard form as
[tex]ax^n+bx^n^-^1+cx^n^-^2+...+px+q[/tex]
Given [tex]4m-2m^4-6m^2-4m+9[/tex]
Combine the like terms: 4m and -4m
4m-4m=0
We have 4m-4m=0
So, write the remaining terms
[tex]-2m^4-6m^2+9+0[/tex]
= [tex]-2m^4-6m^2+9[/tex]
This is in decreasing order of powers.
Hence the answer is the standard form is
[tex]-2m^3-6m^2+9[/tex]
But in the given options, you can choose option 2 and option 3 are in standard form.
Because they are in decreasing order of powers.
In other two options, the constants term is first and the highest power term is at the last. So, they are not in standard form.
-2m^4-6m^2+4m+9
-2m^4-6m^2-4m+9
I hope this helps you.
And please comment if I need to do corrections.

Describe each statement as always, never, or sometimes true.
A weather station on the top of a mountain reports that the temperature is currently 14°C and has been falling at a constant rate of 9°C per hour. If it continues to fall at this rate, find each indicated temperature. What will the temperature be in 2 hours? What will the temperature be in 5 hours? What will the temperature be in half an hour?
Answer: 2 hours=6 degrees C
5 hours=-31 degrees C
Half an hour=9.5 degrees C
I hope this helps. Sorry if I made a mistake. Good luck!
Step-by-step explanation:
9 x 2 hours = 18 C 14-8= 6 degrees C
9 x 5 hours = 45 C 14-45= -31 degrees C
9 x 0.5 = 4.5 C 14-4.5= 9.5 degrees C

Identify the slope and y-intercept of the graph of the equation.
y = $x+3
O slope: 3; y-intercept: 3
1
slope: ; y-intercept: -3
3
O slope: 3; y-intercept: -3
1
slope: ; y-intercept: 3
3
Answer:
Slope = 1/3
Y= 3
Step-by-step explanation:
The equation is given in the form of y=mx+c
Where m=slope and c= y- intercept
Therefore, we can just derive the answer from the form. So y= 3 and the slope =1/3

Match the tangent and sine angles to their expressions.
Answer:
1) [tex]sin \left(\dfrac{- \pi}{12} \right) = \dfrac{(\sqrt{2} - \sqrt{6} }{4}[/tex]
2) [tex]tan\left(\dfrac{ \pi}{12} \right) = 2 - \sqrt{3}[/tex]
3) [tex]tan\left(\dfrac{ 5\cdot \pi}{12} \right) = 2 + \sqrt{3}[/tex]
Step-by-step explanation:
1) [tex]sin \left(\dfrac{- \pi}{12} \right) = sin(-15^{\circ})[/tex]
sin(-15°) = sin(30° + (- 45°)) = sin(30°)cos(-45°) + cos(30°)sin(-45°)
sin(30°)cos(-45°) + cos(30°)sin(-45°) = 1/2 × (√2)/2 + (√3)/2 × (-√2)/2
1/2 × √2/2 + √3/2 × -√2/2 = (√2)/4 - (√6)/4 = ((√2) - (√6))/4
sin(-15°) = ((√2) - (√6))/4
[tex]sin \left(\dfrac{- \pi}{12} \right) = sin(-15^{\circ}) = \dfrac{(\sqrt{2} - \sqrt{6} }{4}[/tex]
2) [tex]tan\left(\dfrac{ \pi}{12} \right) = tan(15^{\circ})[/tex]
tan(15°) = tan(45° + (-30°)) = (tan(-30°) + tan(45°))/(1 - tan(-30°)×tan(45°))
(tan(-30°) + tan(45°))/(1 - tan(-30°)×tan(45°)) = ((-1/√3) + 1)/(1 - (-1/√3))
((-1/√3) + 1)/(1 - (-1/√3)) = (3 - √3)/(3 + √3) = (3 - √3)·(3 -√3)/((3 - √3)·(3 + √3))
(3 - √3)·(3 -√3/((3 - √3)·(3 + √3)) = (9 - 6·√3 + 3)/(9 - 3) = (12 - 6·√3)/6
(2 - √3)
[tex]tan\left(\dfrac{ \pi}{12} \right) = tan(15^{\circ}) = 2 - \sqrt{3}[/tex]
3) [tex]tan\left(\dfrac{ 5\cdot \pi}{12} \right) = tan(75^{\circ})[/tex]
tan(75°) = tan(30° + 45°) = (tan(30°) + tan(45°))/(1 - tan(30°)×tan(45°))
(tan(30°) + tan(45°))/(1 - tan(30°)×tan(45°)) = ((1/√3) + 1)/(1 - 1/√3)
((1/√3) + 1)/(1 - 1/√3) = (3 + √3)/(3 - √3) = (3 + √3)·(3 +√3/((3 - √3)·(3 + √3))
(3 + √3)·(3 +√3/((3 - √3)·(3 + √3)) = (9 + 6·√3 + 3)/(9 - 3) = (12 + 6·√3)/6
(12 + 6·√3)/6 = 2 + √3
[tex]tan\left(\dfrac{ 5\cdot \pi}{12} \right) = tan(75^{\circ}) = 2 + \sqrt{3}[/tex]
Determine which lines, if any, are parallel or perpendicular. Explain
Line a: 2x-7y=14
Line b: y=7/2x-8
Line c: 2x+7y=21
Answer:
line b and c are perpendicular because the product of their slope is -1
Step-by-step explanation:
For two lines to be parallel they must have the same slope
For two line to be perpendicular, the product of their slope must be -1
Line a: 2x-7y=14
Rewrite in the form y = mx+c
-7y = -2x + 14
y = -2/-7 x + 14/-2
y = 2/7x - 7
The slope of line a is 2/7
Line b: y=7/2x-8
This is already in standard format
mx = 7/2 x
m = 7/2
The slope of line b is 7/2
Line c: 2x+7y=21
Rewrite in standard form
7y = -2x + 21
y = -2/7 x + 21/7
y = -2/7 x + 3
The slope of line c is -2/7
Take the product of line b and c
mb * mc = 7/2 * -2/7
mb * mc = -1
Hence line b and c are perpendicular because the product of their slope is -1

What value of x makes this equation true? 25 = -7 + x
Answer:
x=32 makes this equation true
Step-by-step explanation:
Well first we have to solve this to see-
25=-7+x Add 7 to both sides to get x by itself
+7 +7 Adding 7 to -7 makes it 0 so it goes away
32=x This is our final answer
