<h3>35 hot dogs and 52 sodas were sold</h3>
<em><u>Solution:</u></em>
Let "x" be the number of hot dogs sold
Let "y" be the number of sodas sold
Each hot dog costs $1.50 and each soda costs $0.50
<em><u>You sold a total of 87 hot dogs and sodas combined</u></em>
Therefore,
x + y = 87
y = 87 - x -------- eqn 1
<em><u>At the end of the night you made a total of $78.50</u></em>
Therefore,
1.50x + 0.50y = 78.50 ------ eqn 2
Substitute eqn 1 in eqn 2
1.5x + 0.5(87 - x) = 78.5
1.5x + 43.5 - 0.5x = 78.5
x = 78.5 - 43.5
x = 35
Substitute x = 35 in eqn 1
y = 87 - 35
y = 52
Thus 35 hot dogs and 52 sodas were sold
Answer:

Multiply 2.5 and 10
Answer:
slope = 3
Step-by-step explanation:
Use the coordinates of the points to determine the slope.
Answer: 88 degrees; acute triangle
Step-by-step explanation:
All angles of a triangle must add up to 180 degrees. Therefore, to find the value of "x", the work must look like this: 43+49=92 --> 180-92=88. This triangle can be classified as an acute triangle since all of its angles are acute (less than 90 degrees).

Given that P(z > z*) = 16%, mean (μ) = 71, standard deviation (σ) = 15
P(z > z*) = 1 - P(z < z*) = 16%
1 - P(z < z*) = 0.16
P(z < z*) = 0.84
From the normal distribution table, this corresponds with a z score of 1. Hence:
![z*=\frac{x-\mu}{\sigma} \\\\1=\frac{x-71}{15} \\\\x-71=15\\\\x=86](https://tex.z-dn.net/?f=z%2A%3D%5Cfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D%20%5C%5C%5C%5C1%3D%5Cfrac%7Bx-71%7D%7B15%7D%20%5C%5C%5C%5Cx-71%3D15%5C%5C%5C%5Cx%3D86)
