Taxi company A charges $4 plus $2 per mile. Taxi company B charges $5 plus $3 per mile. Which system best represents this problem?
y = 4 x + 0 . 5 , y = 5x + 0.25
y = 4 + 2x , y = 5+3x
y = 4 x + 1 5 , y = 15x + 2
y = - 0 . 5 x + 4 , y = -0.25x + 5
Answer:
The second option
Step-by-step explanation:
To solve this, you should convert both rates to equations, with y being the total fare, and x being the number of miles. The rates of both use the format y=mx+b (where m is the amount per mile and b is the flat rate, or original rate).
By subbing in the values for m and b, you get y=2x+4 for A and y=3x+5 for B. This is the second option.

Answer:
Your answer would be the third one
Step-by-step explanation:
Triangle 1 - 73, 45
Triangle 2 - 47, 30
Triangle 1: 105°, 23° and Triangle 2: 52°, 105 are similar.
Option (4) is correct.
What is a Triangle?A triangle in geometry is a three-sided polygon with three edges and three vertices.
As per the given data:
We are given two angles for each pair of triangles, and we have to find out which of the pair of triangles are similar.
For any two triangles to be similar, it must have 2 angles which are having the same measure.
For, Triangle 1: 55°, 45° and Triangle 2: 55°, 80°
Only one angle is same, hence not similar.
Triangle 1: 103°, 32° and Triangle 2: 103°, 25°
Only one angle is same, hence not similar.
Triangle 1: 73°, 47° and Triangle 2: 47°, 30°
Only one angle is same, hence not similar.
Triangle 1: 105°, 23° and Triangle 2: 52°, 105
By using angle sum property in Triangle 1 the remaining angles is:
= 180 - (105 + 23) = 52°
By using angle sum property in Triangle 2 the remaining angles is:
= 180 - (52 + 105) = 23°
2 angles are same, hence similar.
Triangle 1: 99, 41° and Triangle 2: 40°, 99°
Only one angle is same, hence not similar.
Hence, Triangle 1: 105°, 23° and Triangle 2: 52°, 105 are similar.

Step 1: Add 4 to both sides.
3x−4+4=11+4
3x=15
Step 2: Divide both sides by 3.
3x/3=15/3
x=5

Dan rolls a fair dice and flips a fair coin what is the probability of obtaining an even number and a head
Half the numbers on the die are even so you have a 1/2 probability of getting an even number. There is also. 1/2 probability of getting heads on a coin flip.
To find the probability of both happening, multiply the probability of each together:
1/2 x 1/2 = 1/4
The probability of getting an even number and heads is 1/4
Bart is collecting data on sunflower growth. He records the height, in inches, of his sunflower each day. Which best describes the type of data Bart is collecting
Answer:
Numerical data
Step-by-step explanation:
Given
Height recorded on a bar chart
Required
The type of data
From the question, we understand that the height is being recorded.
Height of flowers are numbers (e.g. 6in, 5in. 3in etc.).
When data are presented in numbers (i.e. digits), such data are referred to as numerical data.
Match each power of a power expression with its simplified expression
= 4⁰×-⁹
= 4⁰
(-4⁹)²= -4⁹ײ
= -4¹⁸
=( -4)¹⁸
(4-³)-³= 4-³ × -³
= 4⁹
(4⁶)-³= 4⁶ × -³
= 4-¹⁸
= 1/4¹⁸

Answer:
A. 25/33
B. 1/3
C. 1/33
D. 25/9
Answer:
[tex]\text{A. }25/33,\\\text{B. }1/3, \\\text{C. }1/33, \\\text{D. }25/9[/tex]
Step-by-step explanation:
Recall that [tex]\frac{x}{9}=0.\overline{x}[/tex] for [tex]x\in (1, 8)[/tex]. If multiple digits are repeating, increase the number of nines in the denominator as applicable.
Therefore, we have:
Part A:
"75" is repeating:
[tex]\rightarrow \frac{75}{99}=\boxed{\frac{25}{33}}[/tex]
Part B:
"3" is repeating:
[tex]\rightarrow \frac{3}{9}=\boxed{\frac{1}{3}}[/tex]
Part C:
"03" is repeating:
[tex]\rightarrow \frac{03}{99}=\frac{3}{99}=\boxed{\frac{1}{33}}[/tex]
Part D:
"7" is repeating, but there is a terminating decimal 2.0 with it ([tex]2.\overline{7}=2.0+0.\overline{7}[/tex]):
[tex]2+\frac{7}{9}=\frac{18}{9}+\frac{7}{9}=\boxed{\frac{25}{9}}[/tex]

what is the solution to this system of equations?
Answer:
(0, -5)
Step-by-step explanation:
Multiply both sides of the second equation by 6 to get 6y=3x+30. Then, subtract the second equation from the first to cancel out the x's. y-6y=-5y, 3x-5-3x-30=-25. -5y=-25, so y=-5. Substitute -5 into the first equation to get 3x-5=-5, add five to both sides: 3x=0, divide by 3: x=0. The ordered pair is (0, -5). Hope this is correct and helps! :)

what is an expression showing the sum of 5 less than the number k
Answer:
5<k
Step-by-step explanation:
Answer:
k-5
Step-by-step explanation:
So, lets go over each part of the sentence, and turn it into a expression.
So it first says sum. This means addition, so we can start our expression with:
+
Next is says of 5. So we know its the addition of 5:
+5
Next it says less than. So now we know less than, which is subtraction. So we can swap the addition sign for a - sign:
-5
Finally it says the number k. So we know that the subtracted value is k:
k-5
So this is your expression!
Hope this helps!

Based on histogram above what is the average number of hours worked by 20 salesperson in company G
Answer:
[tex]Average = 38[/tex]
Step-by-step explanation:
Given
The attached histogram
Required
The average work hours by 20 salespeople
First, we get the total hours worked as follows:
[tex]Hours = 3 * 30 + 5 * 34 + 9 * 40 + 2 * 45 + 1 * 50[/tex]
[tex]Hours = 760[/tex]
Divide by number of salespeople
[tex]Average = Hours/n[/tex]
[tex]Average = 760/20[/tex]
[tex]Average = 38[/tex]

Taking L.C.M. of the denominators 7, 11, 21 and 22 and then solving it.
L.C.M. of 7, 11, 21 and 22 = 2 x 3 x 7 x 11 = 462

Answer:
length =105 width =10
Step-by-step explanation:
L=10*W+5
P=230
P=2(L+W)
230=2(10W+5+W)
SOLVE FOR W
W=10
L=10*W+5
=10*10+5
L=105
A person's Body Mass Index (BMI) is a measure of the mount of fat in their body. The relationship between antioxidant food consumption per day in cups and the BMI of an individual is modeled by the following line of best fit: y = -0.1x + 22. Interpret the slope and intercept of the trend line within the context of the data.
Answer:
Check explanation
Step-by-step explanation:
Given:
y = -0.1x + 22
Where,
y = BMI of an individual
x = antioxidant food consumption per day in cups
Equation of a slope
y = mx + c
Where,
m = slope
c = y - intercept
Therefore,
From the equation
y = -0.1x + 22
slope, m = -0.1
y - intercept, c = 22
Answer:
The y-intercept tells us that a person who doesn’t have any antioxidant foods can expect to have a BMI of 26. For every cup of antioxidant food that is consumed one can expect to lower their BMI by 1.2.

[tex]F = \frac{9}{5}C+32[/tex]
Subtract 32 from both sides
[tex]F-32= \frac{9}{5}C\\[/tex]
Multiply both side by 5/9
[tex]\frac{5}{9}(F-32)=( \frac{5}{9})* \frac{9}{5}C\\\\ \frac{5}{9}(F-32)=C\\[/tex]
F= 41
[tex]\frac{5(41-32)}{9}=C\\\\ \frac{5*9}{9}=C\\\\ \frac{45}{9}=C\\\\C = 5\\\\[/tex]
