You can solve this problem with the following 

\frac{1}{10} =  \frac{a}{190}
10a = 190
a = 19

There should be 19 adults on the trip.

When baking a cake you can choose between a round pan with a 9 in. diameter and a 8 in. times 11 in. rectangular pan?
ivanzaharov [21]

Question says that there are two type of pans.

First pan has diameter of 9 inches.

Second pan has dimension 8 inches by 11 inches. Which means second pan is rectangular.

It seems you missed few parts of the question like what we have to do with it. I searched for similar question on internet and found that they are finding surface area of the both pans so i will tell you how to find that.


Radius of the circular pan = diameter/2 = 9/2 = 4.5 inches

Then surface area of the first (circular) pan = \pi r^2 = 3.14 *4.5^2 = 63.585 square inches.


Now surface area of second (rectangular) pan is given by formula of area of rectangle

Area = Length * width = 8*11= 88 square inches.

Find an equation of a sphere if one of its diameters has endpoints (3, 2, 5) and (5, 6, 7). Incorrect: your answer is incorrect.
prohojiy [21]

use midpoint equation

radius = distance between midpoint and one of the endpoints.

midpoint: (3+5)/2, (2+6)/2, (5+7)/2 = (4,4,6)

equation of sphere: (x-4)^2 + (y-4)^2 + (z-6)^2 = r^2

square distance between midpoint and one of the endpoints.

r^2 = 6

Equation: (x-4)^2 + (y-4)^2 + (z-6)^2 = 6

Laura invests $2500 in one account and $1500 in an account paying 2 % higher interest. At the end of one year she had earned $11
Crank

Answer:

$2500 - 2%

$1500 - 4%

Step-by-step explanation:

Say the interest for the $2500 is x, so the interest for the $1500 is x+0.02.

As an equation, they would look like this:

2500x+1500(x+0.02)=110

Now solve

2500+1500x+30=110

4000x=80

x=0.02

That means the interest for the $2500 is 0.02, or 2%, and the interest for the $1500 is 0.04, or 4%.

Use the number line below, where RS = 7y +3, ST = 5y +8, and RT = 83.
Llana [10]

Answer:

Step-by-step explanation:

Given the vectors based on the number line as RS = 7y +3, ST = 5y +8, and RT = 83, the equation RS+ST = RT will be used to get the unknown.

Substituting the given equation into the expression we will have;

7y +3+5y +8 = 83

collect like terms'

7y+5y+3+8 = 83

12y + 11 = 83

12y = 83-11

12y = 72

y = 72/12

y = 6

b) Substitute y = 6 into RS and ST

Given RS = 7y+3

RS = 7(6)+3

RS = 42+3

RS = 45

For ST;

ST = 5y+8

ST = 5(6)+8

ST = 30+8

ST = 38
