A gift basket has 2 soaps and 5 lotions and costs $20. A second basket has 6 spas and 15 lotions and cost $60. Is it possible to
kifflom [539]

A second basket has 6 spas--- I think you mean 6 soaps , so i will work with that

Answer:it is not possible to determine the price of the soap with the information given.

Step-by-step explanation:

Let s0ap be represented as x

and lotion be represented as y

2 soaps and 5 lotions costing  $20 gives us equation 1 as

2 x+ 5y= 20-------- equation 1

second basket with 6 soaps and 15 lotions and costing $60 gives us equation 2 as

6x + 15y= 60------equation 2

Step 2 -- Solving

2 x+ 5y= 20-------- equation 1

6x + 15y= 60--------equation 2

BY elimination method, we  multiply equation 1 by (3)

2x + 5y= 20  x (3)

6x + 15y=60-------equation 3

Subtraction of equation 3 from equation 2 gives us

6x + 15y=60-------equation 3

-6x + 15y= 60--------equation 2

0x +0y=0  which is no solution

Therefore it is not possible to determine the price of the soap

A restaurant wants to study how well its salads sell. The circle graph shows the sales over the past few days. If 35 of the sala
balu736 [363]
The restaurants sold 50 salads.

-The given is that they sold 35 garden salads which is 70% of their sales.
-Now, to get how many salads 1% is equal to, you divide 35 by 70
-35/70 = 0.5
-So now, multiply 16 by 0.5 and 14 by 0.5
-16(0.5)=8 and 14(0.5)=7
-Add the three together to get 50
-Now, check to see if it works
70% of 50 is 35
16% of 50 is 8
14% of 50 is 7

Hope this helps and is right, have a good day!

Two aquariums are shaped like a rectangular prism the ratio of the dimensions of the larger aquarium to the dimensions of the sm
Daniel [21]

Answer:

Cathy was right ( kinda)

Step-by-step explanation:

let the dimension of the small one be 2a : 2b : 2c

then the dimension of the big one be 3a : 3b : 3c

volume of small: 2a*2b*2c = 8 abc

volume of big: 3a*3b*3c = 27 abc

volume ratio: big/ small = 27/8 = 3.375

-> big one hold 237.5% more than small

-> Cathy was right ( kinda)

CALCULUS EXPERT WANTED. Can someone solve this or at least try to explain to me the fundamental theorem of calculus (FTC).
Amanda [17]

a. By the FTC,

\displaystyle\frac{\mathrm d}{\mathrm dx}\int_1^{\cos x}(t+\sqrt t)\,\mathrm dt=(\cos x+\sqrt{\cos x})\dfrac{\mathrm d}{\mathrm dx}\cos x=-\sin x(\cos x+\sqrt{\cos x})

b. We can either evaluate the integral directly, or take the integral of the previous result. With the first method, we get

\displaystyle\int_1^{\cos x}(t+\sqrt t)\,\mathrm dt=\dfrac{t^2}2+\dfrac{2t^{3/2}}3\bigg|_{t=1}^{t=\cos x}=\left(\dfrac{\cos^2x}2+\dfrac{2(\cos x)^{3/2}}3\right)-\left(\dfrac12+\dfrac23\right)

=\dfrac{\cos^2x}2+\dfrac{2\sqrt{\cos^3x}}3-\dfrac76

c. The derivative of the previous result is

\dfrac{2\cos x(-\sin x)}2+\dfrac{2\cdot\frac32(\cos x)^{1/2}(-\sin x)}3=-\sin x\cos x-\sin x\sqrt{\cos x}

which is the same as the answer given in part (a), so ...

d. ... yes
