The figure shows a block of stone measures 8 cm by 5 cm by 2 cm and has a density of 2.5 g/cm3
what is the volume of the stone?
what is the mass of the stone?
Step-by-step explanation:
The volume of the stone = 8 × 5 × 2 = 80
Using density = mass / volume
So 2.5 = mass / 80
2.5 × 80 = mass
200 = mass
please give me brainliest answer
volume:
(8cm×5cm×2cm)=80cm³
I don't know the mass , sorry

Answer:
1)
Ola taxi charges a $8 flat rate in addition to $2 per mile. Paul has no more than $10 to spend on a ride.
2)
Let x be the number of miles.
Then, we have inequality: 8x+2<=10
Solve the inequality: 8x+2<=10
Subtract 2 from both the sides:
8x+2-2<=10-2
Simplify
8x<=8
:
Divide by 8 both sides we get
x<=1;
as shown in figure 1.
4)
From the context of the problem :
we can say that Paul can travel 1 miles or less before reaching his limit of $10.

Answer:
-2/3x+4
Step-by-step explanation:
the reason is that if we take 2 point from the graph for example;
0,4 and 6,0
1) to get the gradient it is y2-y1/x2-x1
sub 0,4 and 6,0 into the equation from 1
4-0/0-6 which is 4/-6
4/-6 = 2/-3 and +4 because as seen in the graph it's hits the y-axis at +4
so it is 2/-3x + 4

Answer:
correct the answer is 7[tex]\frac{1}{2}[/tex]
Step-by-step explanation:
The required cups of floor needed to make his cookies is 7 1/2 cups. Option D is correct.
Given that,
Nate is baking cookies for a bake sale. He needs 2 1/4 cups of flour for each batch of cookies, and he needs to make 3 1/3 batches, how much flour does Nate need to make his cookies is to be determined.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Amount of floor for each batch of cookie = 2 1/4
Total floor required to bake 3 1/3 batches = 9 / 4 × 10 / 3 = 7 1 / 2
Thus, the required cups of floor needed to make his cookies is 7 1/2 cups. Option D is correct.

so if he started with 0 frames
time s = (1/24) (additional f)
but he already had at least 250 frames
so
time s = (1/24)( f-250) or maybe less time if he had more than 250
24 s </= f - 250
or

Amelie has three dogs, Max, Jasmine, And Springer. She buys a bag of dog food that contains a special mix.
Each dog gets a different amount of the food based off of there weight. Max gets 1/4 of the bag, Jasmine gets 1/3 of the bag, and Springer gets the rest. what fraction of the bag dose Springer get?
I will give BRAINLIEST to the person that solves this.
If Max gets 1/4 of the bag, Jasmine gets 1/3 of the bag then Springer gets 5/12 of the bag of dog food.
What is Fraction?A fraction represents a part of a whole.
Given that Amelie has three dogs, Max, Jasmine, And Springer.
Max gets 1/4 of the bag, Jasmine gets 1/3 of the bag, and Springer gets the rest.
We have to find the fraction of the bag dose Springer get
Let's first add up the portions of food that Max and Jasmine get.
Max's portion = 1/4
Jasmine's portion = 1/3
The total of their portions is:
1/4 + 1/3 = 3/12 + 4/12 = 7/12
This means that Springer gets the remaining portion of the bag:
1 - 7/12 = 5/12
Therefore, Springer gets 5/12 of the bag of dog food.

The graph shows the number of servings in different amounts of frozen yogurt listed on a carton. Enter an equation that gives the number of servings y in x pints. Use only decimal form, if necessary.
The equation is y =
Answer:
y=2.5x
Step-by-step explanation:
We have been given a graph that shows numbers of servings (y) in different amounts (x) of frozen yogurt listed on a carton.
To write an equation that gives the number of servings y in x pints, we will have to find the slope (rate of change) of our given linear function.
Since we know that rate of change of a function can be found by vertical change of the function divided by horizontal change of the function.
m= Slope (rate of change).
=Difference between two y-coordinates.
=Difference between corresponding x-coordinates of the y-coordinates.
Upon substituting coordinates of two points (0,0) and (4,10) in slope formula we will get,
The slope of our given line is 2.5.
Now we will write equation of our given line is slope-intercept form. The equation of a line in slope-intercept form is: , where m=slope and b = y-intercept (initial value).
Upon substituting m=2.5 and coordinates of point (4,10) in slope-intercept form of equation we will get,
Upon substituting m=2.5 and b=0 in slope-intercept form of equation we will get,
Therefore, the equation will give the number of servings y in x pints.
