Answer:

B. The rent and savings account for more than 50% of the budget.

Step-by-step explanation:

The rent and savings account for a total of $1,500 which is exactly 50% of the budget. You can tell this is 50% of the budget because if you multiply it by 2, you get the entire budget. This question said it accounts for <u>more</u> than 50% which is false.

n200080 [17]

Answer:

For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters. Notice that gravitational potential energy has the same units as kinetic energy, kg m2 / s2.

The school that Stefan goes to is selling tickets to a choral performance. On the first day of ticket sales the school sold 3 se

Afina-wow [57]

Start by writing out the information you know mathematically (I used S for cost of senior ticket, and C for cost of child ticket. You could use X and Y, or any other combination of letters as variables)

3s + 1c=38
3s + 2c=52

Now, you'll want to eliminate one of the variables by subtracting it out. Remember - Same sign, subtract (and therefore different sign, add).

In this case, 3s exists in the first and second equation, so it's very easy to get rid of. They're both positive, so they have the same sign (+). Same sign, subtract.
3s + 1c=38
-(3s + 2c=52)
__________
0 -1c= -14
-c=-14
C=14

Now, plug c=14 into either of the original equations.

3s + C= 38
3s + 14=38
3s=24
S=8.

So, a child ticket costs $14 and a senior ticket costs $8.

By what percent will the product of two numbers change, if the first number increases by 70%, while the second number decreases

erica [24]

Answer:

The product of two numbers changes by 2% when the first number increases by 70%, while the second number decreases by 40%.

Step-by-step explanation:

Let first number be x and second number be y .

Then product of x and y = xy ......(1)

Given the first number increases by 70%, while the second number decreases by 40% this means,

x is increased by 70% that is

increased value of x = x + 0.7(x) = 1.7 x
