Step-by-step explanation:
A gorilla needs to eat at least 40 pounds of food each day. The zoo feeds the gorilla using canisters that contain 4 pounds of food. The gorilla
has already consumed 28 pounds of food. How many more canisters z of food does the gorilla need to ear? Write your answer as an inequality.
Answers
At least would be present as using ≥ or greater than or equal to symbol.
So far the gorilla has consumed 28 pounds of food and each can contains 4 pounds of food.
So: 28 pounds of food/ 4 pounds of food per can= 7 cans consumed
40 pounds needed - 28 pounds consumed= 12 pounds left
12 lbs/ 4 lbs per can= 3 cans left for the gorilla to exceed its goal

which ideas about functions are the most helpful
Answers
It helps in calculating the price of groceries such as fruits.
Step-by-step explanation:
Remember, functions are mathematical expressions that represent or shows the relationship between one or more variables.
For example, let's say a young girl wants to shop for 20 oranges in a mall. If we express the price using the function where;
y represents the total cost of the oranges,
20 represents the number of oranges,
x represents the cost per orange (assumed to $0.99)
Then, by means of the knowledge of function, the girl determines the total cost she to be $19.8 (20*0.99).

write a general formula to describe the variation: S varies jointly with the inverse of the square of P and the inverse of the cube of L; S=4 when P=2 and L=5
Answers
Answer:
S=2000/P^2L^3
Step-by-step explanation:Step 1:Write the correct equation. Combined variation problems are solved using a combination of direct variation (y = kx), inverse variation , and joint variation (y = kxz) equations. When dealing with word problems, you should consider using variables other than x, y, and z, you should use variables that are relevant to the problem being solved. Also read the problem carefully to determine if there are any other changes in the combined variation equation, such as squares, cubes, or square roots.Step 2:Use the information given in the problem to find the value of k, called the constant of variation or the constant of proportionality.Step 3:Rewrite the equation from step 1 substituting in the value of k found in step 2.Step 4:Use the equation found in step 3 and the remaining information given in the problem to answer the question asked. When solving word problems, remember to include units in your final answer.

Step-by-step explanation:
Which linear function represents the line given by the point-slope equation y + 1 = –3(x – 5)?
f(x) = –3x – 6
f(x) = –3x – 4
f(x) = –3x + 16
f(x) = –3x + 14
Answers
Answer:
f(x) = -3x + 14
Step-by-step explanation:
y + 1 = -3(x - 5)
solving,
y + 1 = -3x + 15
y = - 3x + 14
we know that f(x) = y so,
f(x) = -3x + 14
Based on the cards shown, what is P(pink or even)?
1/5
7/10
9/10
Answers
Answer:
7/10
Step-by-step explanation:
To solve this, first find how many of the cards or even. There are 5 even cards out of these 10 cards, so we have the fraction 5/10. Next, we can see that there are 4 pink cards. So, we also have the fraction of 4/10. Then, add these two fractions.
5/10 + 4/10 = 9/10.
But, since the pink 8 card and the pink 10 card are both pink and even, they were counted twice. So, we need to subtract 2/10 from 9/10. This is 7/10.

Ok thank you
Answer:
its 7hrs
Step-by-step explanation:
Another way to think about it
Every hour, they get 7 miles apart from each other
Since one is 7 miles per hour faster than the other
7*h is their separation for h hours.
Solving 7*h = 49 gets you the hours for which the separation is 49 miles
