I will use ratios for this equation:
[tex]\frac{1}{45} =\frac{x}{180} \\\\45x=180\\x=4[/tex]
It will take Zahra 4 minutes to read 180 words because she reads 45 words PER minute.
If you know that the hypotenuse of a 30-60-90 triangle is 124 cm, explain how you find the lengths of the other two sides.
Answer:
Length of short side is 62 cm and length of long side is [tex]62\sqrt{3}[/tex] cm
Step-by-step explanation:
There's specific "rule" for 30-60-90 triangle
short leg will be x
long leg will be [tex]x\sqrt{3}[/tex]
hypotenuse will be 2x
So, when you know hypotenuse is 124 (2x)
To find short leg, you divide 124 by 2
short leg will be 62 (x)
To find long leg, you plug in the x (in this case it's 62)
long leg will be [tex]62\sqrt{3}[/tex]

A car travels at a constant speed of 40 mph on the highway. Write an expression to find the distance the car travels for any number of hours. Let the variable h represent the number of hours.
Answer: [tex]40h[/tex]
Step-by-step explanation:
Given
Speed of car is [tex]40\ mph[/tex]
We know, distance is given by
[tex]\text{Distance=}\text{speed}\times \text{time}[/tex]
Let h represents the number of hours
So, the distance traveled with speed [tex]40\ mph[/tex] in 'h' hours
[tex]\Rightarrow d=40\times h\\\Rightarrow d=40h[/tex]
So, the expression is given by [tex]40h[/tex]
Which equation is the universe of y=9x^2-4
Step-by-step explanation:
keep in mind that, to get the inverse expression of any relation, we start off by doing a quick switcheroo on the variables, and then solve for "y", so let's do so,
Answer:
[tex]y = \frac{\sqrt{x+4} }{3}, \ y = -\frac{\sqrt{x+4} }{3}[/tex]
Step-by-step explanation:
To find inverse we replace and y first.
[tex]y = 9x^2 - 4 \ becomes \ x = 9y^2 -4[/tex]
[tex]Then \ solve \ for \ y\\\\9y^2 = x+ 4\\\\y^2 = \frac{x+4}{9}\\\\y = \pm \sqrt{\frac{x+4}{9}} \\\\y = \pm {\frac{\sqrt{x+4}}{3}[/tex]
Determine whether the given sequence could be geometric, arithmetic, or neither. If possible identify the common ratio or common difference 1/2,5/4, 2, 11/4..
Answer:
It is an Arithmetic sequence
Common difference = 3/4
Step-by-step explanation:
Determine whether the given sequence could be geometric, arithmetic, or neither. If possible identify the common ratio or common difference 1/2,5/4, 2, 11/4..
We are given the sequence:
1/2, 5/4, 2, 11/4.
We are to determine if this is an Arithmetic or Geometric sequence
Hence:
To determine if this is an Arithmetic sequence, we find the Common difference
Common difference = Second term - First term
= 5/4 - 1/2
Lowest Common Denominator = 4
= 5 - 2/4 = 3/4
or Third term - Second term
2 - 5/4
Lowest Common Denominator = 4
2/1 - 5/4
8 - 5/4
= 3/4
We have the same common difference.
To determine if this is an Geometric sequence, we find the Common ratio
Common ratio = Second term / First term
= 5/4 ÷ 1/2
5/4 × 2/1
= 5/2 = 2 1/2
or Third term /Second term
2 ÷ 5/4
2 × 4/5
= 6/5
= 1 1/5
It is not a geometric sequence
Therefore , the above sequence in the Question is an Arithmetic sequence.

Janna has driven 200 miles. If she averages 50 miles per hour, how many more hours must she drive before she has driven a total of 500 miles?
A diver is currently at an elevation of -380 feet. Write an absolute value statement to express the diver's distance, in feet, from sea level. Then, interpret the result in this situation by explaining what this means for the diver.
Answer:
The absolute value function:
f(x) = |x|
is defined as:
f(x) = x if x ≥ 0
f(x) = -x if x < 0.
Then, knowing that the elevation of the diver is -380 ft
We can write the absolute value of the distance as:
|-380ft| = -(-380ft) = 380ft
This means that the diver is at a distance of 380 ft from sea level. (And because we know that the sign is negative, we can conclude that he is 380ft below sea level).

Answer:
Y remains unchanged because y is still 7.
Which fraction is the closest estimate to √10
1. 2 1/2
2. 3 1/5
3. 3
4. ⅒
Answer:
Step-by-step explanation:
(√10)²=10
1. (2 1/2)²=(5/2)²=25/4=6.25
2. (3 1/5)²=(16/5)²=256/25=10.24
3. 3²=9
4. (1/10)²=1/100=0.01
we see 10.24 is near to 10
so 3 1/5 is closest.

100 x 50 =5,000
10 x 500 = 5,000
What is the equation of the line that passes through the point (-7, -7) and
has a slope of 1?
Answer:
[tex]y=x[/tex]
Step-by-step explanation:
Hi there!
What we need to know:
Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axisy and x stay as they are while m and b are replaced with numerical values1) Determine the slope (m)
[tex]y=mx+b[/tex]
We're given that the slope of the line is 1. Plug this into the above equation
[tex]y=1x+b\\y=x+b[/tex]
2) Determine the y-intercept (b)
[tex]y=x+b[/tex]
Plug in the given point (-7,-7)
[tex]-7=-7+b[/tex]
Add 7 to both sides to isolate b
[tex]-7+7=-7+b+7\\0=b[/tex]
Therefore, the y-intercept is 0. Plug this back into [tex]y=x+b[/tex]
[tex]y=x+0\\y=x[/tex]
I hope this helps!

If the board length of an average log is 8.25 and the price per board foot is 7.95. What is the value of the timber if there are 100 logs?
Answer:
6558.75
Step-by-step explanation:
total value of 100 logs = total value of an average log x 100 total value of an average log = length of an average log x price per board foot
8.25 x 7.95 = 65.5875
65.5875 x 100 = 6558.75

The number line is labeled, age, in years, and ranges from 15 to 65. Based on the data shown in the box-and-whisker plot above, what is the interquartile range of the ages, in years, of the trees? Respond in the space provided. If your test is on paper, write your answer on the answer she
Answer:
[tex]IQR = 15[/tex]
Step-by-step explanation:
Given
I will answer this question with the attached plot
Required
The interquartile range (IQR)
This is calculated using:
[tex]IQR = Q_3 - Q_1[/tex]
On the second attachment, I identified Q1 and Q3 on the plot.
So, we have:
[tex]Q_3 = 40[/tex]
[tex]Q_1 = 25[/tex]
[tex]IQR = Q_3 - Q_1[/tex]
[tex]IQR = 40 - 25[/tex]
[tex]IQR = 15[/tex]

Answer:
Option B
Step-by-step explanation:
Equation of the graph,
f(x) = x²
If the graph is translated 5 units to the right,
g(x) = f(x - 5)
Therefore, g(x) = (x - 5)²
If the function 'g' is translated 3 units up,
h(x) = g(x) + 3
Therefore, h(x) = (x - 5)² + 3
If the function 'h' is vertically compressed by a factor of [tex]\frac{2}{3}[/tex],
Then the new function will be,
k(x) = [tex]\frac{2}{3}(x-5)^2+3[/tex]
Option B will the correct option.
