At a carnival, food tickets cost $2 each and ride tickets cost $3 each. A total of $1,240 was collected at the carnival. The num

ber of food tickets sold was 10 less than twice the number of ride tickets sold.
The system of equations represents x, the number of food tickets sold, and y, the number of ride tickets sold.

2x + 3y = 1240

x = 2y – 10

How many of each type of ticket were sold?

The given equations satisfy the given conditions. There are 2 equations and 2 unknowns, so a certain solution can be found.

This can be solved using substitution,

Substituting eqn 2 to eqn 1:

2(2y – 10) + 3y =1240

Simplifying,

y = 180

x = 350

assuming that tide duration from low tide to high tide is 6 hours and 25 minutes, going from a high of 3.21ft and down to a low
mixer [17]
To answer this you will need to write the ratio of difference in the tides over the amount of time that goes by.

1. 3.21 ft - 0.20 ft= 3.01 ft change.
2. 3.01 change over 6 5/12 hr.
3. Divide these to find the lapse rate per hour. This is about 0.47 ft per hour.

At a certain time of the day, a tree 15 m tall casts a shadow of 12 m, while a second tree casts a shadow of 20 m. How tall is t
Anna35 [415]
We can write a proportion: 15 m is to 12 m as some other height h is to 20 m

So we get
\frac{15}{12}=\frac{h}{20}
\rightarrow 15*20=12h
\rightarrow 12h=300
\rightarrow h=25

So the second tree is 25 m tall.

Your family is going on a road trip to Disney World! On Day 1, you traveled x miles. On Day 2, you drove 58 miles more than 3 ti
ladessa [460]
First we write the expressions of each day separately:
 Day 1:
 you traveled x miles:
 x
 Day 2:
 you drove 58 miles more than 3 times the thousands on Day 1:
 3x + 58
 Day 3: 
 your family went 25 fewer thousands than Day 1
 x-25
 Then, we have:
 Day 1 + Day 2 + Day 3:
 x + (3x + 58) + (x-25)
 Rewriting:
 x + 3x + x + 58 - 25
 5x + 33
 Then, for x = 100
 5 * (100) + 33 = 533 miles.
 answer:
 5x + 33
 Total miles that family traveled from home to Disney World is
 533 miles

About % of the area under the curve of the standard normal distribution is between z = − 0.9 z = - 0.9 and z = 0.9 z = 0.9 (or w
prisoha [69]

Using the normal distribution, it is found that 63.18% of the area under the curve of the standard normal distribution is between z = − 0.9 z = - 0.9.

<h3>Normal Probability Distribution</h3>

The z-score of a measure X of a normally distributed variable with mean \mu and standard deviation \sigma is given by:

Z = \frac{X - \mu}{\sigma}

  • The z-score measures how many standard deviations the measure is above or below the mean.
  • Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

The area within 0.9 standard deviations of the mean is the <u>p-value of Z = 0.9(0.8159) subtracted by the p-value of Z = -0.9(0.1841)</u>, hence:

0.8159 - 0.1841 = 0.6318 = 63.18%.
