Please someone help me ASAP.

Mathematics
1 answer:
k0ka [10]3 years ago
4 0

Answer:

£13

Step-by-step explanation:

Set up a system of equations where s represents the cost of one shirt and j represents the cost of one jumper:

2s + j = 29

s + j = 21

Multiply the bottom equation by -2 to solve by elimination by cancelling out the s variables:

2s + j = 29

-2s - 2j = -42

-j = -13

j = 13

One jumper will cost £13

What is the volume of this right cone?
defon

Question:

What is the volume of this right cone?

40π cm³

300π cm³  

400π cm³  

480π cm³

The image of the cone is attached below:

Answer:

Option c: 400π cm³  

Explanation:

It is given that a right cone with radius = 10 cm , height = 12 cm and lateral height 15.6 cm

To determine the volume of the right cone, let us substitute these values in the formula,

V=\frac{1}{3} \pi r^{2}  h

Thus, we get,

V=\frac{1}{3} \pi (10)^{2}(12)

Multiplying the terms,

V=\frac{1}{3} \pi (1200)

Dividing by 3, we get,

V=400 \pi

Thus, the volume of the cone is 400π cm³  

Hence, Option c is the correct answer.

The cost of renting an apartment can be modeled by the function C(m)=900m+1400, where C(m) is the cost in dollars for m months o
Ahat [919]

Answer:

On the context of the problem, the slope means the total paid for every month that the apartment is rented, 900 per month in this case, while the y-intercept means the initial cost for renting the apartment, 1400 upfront in this case.

Step-by-step explanation:

This function is linear, which means that it increases at a steady rate and has the following form:

y(x) = a*x + b

Where "a" is the slope or the rate at which "y" changes for every change in "x". While "b" is the number at which the function crosses the "y" axis.

On the context of the problem, the slope means the total paid for every month that the apartment is rented, 900 per month in this case, while the y-intercept means the initial cost for renting the apartment, 1400 upfront in this case.

Am i doing this right? Confused
aliya0001 [1]
No you aren’t but your close. You are writing how much each pan makes instead of how many time you need it to make 30. A for example makes 15 muffins, so you take the 30 muffins you need and divide it by how many muffins you can make in one pan. So 30/15 would be 2 times she’d need the pan, that’s the answer for A. B makes 6 muffins, so 30/6=5 times she’d need the pan. Understand?
