Lucia rode her bike for 1 3/8 miles on Wednesday. On Thursday she biked 7 3/8 times as far as on Wednesday. How many miles did Lucia bike on Thursday
Answer:
10 9/64
Step-by-step explanation:
To answer this, multiply '1 3/8 miles' by '7 3/8.'
The improper fraction form of '1 3/8' is 11/8, and that of 7 3/8 is 59/8.
Multiplying 11/8 by 59/8, we get 649/64, or (as a mixed number) 10 9/64
A teacher instructed her students to draw an isosceles triangle that has at least one angle that
measures 75° and exactly one side that measures 12 centimeters.
Using the teacher's instructions, how many different triangles can be drawn that have the same
angle and side measures? Enter your answer in the box.
The number of different triangles that can be drawn that have the same angle and side measures will be 2.
What is an isosceles triangle?It should be noted that an isosceles triangle simply means a triangle that has two sides that are of equal length.
In this case, the number of different triangles that can be drawn that have the same angle and side measures will be 2. The angle is 75° and side length is 12cm.

The volume of the cube below is 250.047 cm^3. The side lengths could be between which sets of numbers below
A. 4cm and 5cm
B. 5cm and 6 cm
C. 6cm and 7 cm
D. 7cm and 8cm
Answer:
C. 6cm and 7 cm
Step-by-step explanation:
The volume of a cube is calculated by finding the third power of a side length which is basically multiplying the value by itself three times (a^3 = a*a*a)
Let a represent the side length
a^3 = 250.047 cm^3 (approximately 250) we can try each option one by one to find the nearest result:
A)
the third power of 4 is 64 and the third power of 5 is 125 so this is not the answer we are looking for
B)
The third power of 5 is 125 and the third power of 6 is 216 so this is also not the answer we are looking for
C)
the third power of 6 is = 216 and the third power of 7 is 343
now 250 is between these values so this is the answer we are lookign for
Determine if √2 is rational or irrational and give a reason for your answer.
Answer:
√2 is irrational
Step-by-step explanation:
√2 is irrational because you cannot write it as a fraction of rational numbers. Some good approximations of √2, however, are 99/70, 577/408, and 665857/470832.

Use the image above to identify and explain the relationship between the segments and circles A and B. In your
explanation, be sure to include specific vocabulary and definitions for the relationships.
PS
Answer:
Step-by-step explanation:
From the given figure, it can be seen that there are two circles with centers A and B respectively. The circle with the center A is larger in size than the circle with center B. Points P, Q and E lie on the surface of the circle having center A and R, S, C and T points lie on the circle having center B.
One tangent passes from the point Q of the one circle to the point T of the another circle and the other tangent passes from point R of the smaller circle to the point E of the larger circle. These two tangents intersects each other outside both the circle. There is another tangent which passes from the point C of the smaller circle to a point D lying outside the circle.

Find the equation of the line shown
Answer:
y = 2x
Step-by-step explanation:
Use y = mx + b to write an equation. The y-intercept is zero. This is where the line crosses the y -axis, kind of the "starting point" So in the equation the b is a zero.
You can grab a couple points from the line to do a calculation for slope. BUT, you can actually SEE the slope on this line and save yourself the calculation. Starting from zero, see that you go UP 2 and OVER 1 to get to the next point. UP2OVER1 gets you to the next point and the next point. UP2OVER1 is the slope 2/1, which is 2, which is the m in the equation.
y = 2/1 x + 0
y = 2x + 0
y = 2x
**in case you have to show a calc for slope. Grab two points and do y-y, put that on top and then x-x and put that on the bottom.**

Maria deposited 1200 in savings account for 5 years. The
interest rate is 4. 5%. What will be total balance in her account
after 5 years.
Answer:
compound interest would be,
1495.91
and simple interest would be,
1470
Step-by-step explanation:
compound interest would look like,
1200 x 1.045 x 1.045 x 1.045 x 1.045 x 1.045
and simple interest would look like,
1200 x 0.045 = 54 = 4.5%
54 x 5 = 270
1200 + 270 = 1470
Solve for x, please show work
Here is how you solve for x:
9x - 43/ 3x + 29
1: First, you add like terms. In this case, it is 9x and 3x. 9x + 3x= 12x
2: Then, you have -43 and 29 left. -43 + 29= -14 because you do 43 - 29 and keep the sign of the larger number.
3: Lastly, we have a one-step equation left to solve: 12x-14. So, now we do this:
- divide both sides by 12.
- -14/12= 1.67
x= -1.67

what's the constant rate on this?
Answer:
Constant Rate = -2
Step-by-step explanation:
To find the constant rate or slope, you can use Change in Y-Value/Change in X-Value using two points. (Rise/Run). You can use any two points.
From that you should be able to get -2.
52% of 1000 registered voters intend to vote for Steven Collins for mayor. Based on a 95% confidence interval, can we assume that Steven Collins will win the election if all votes are cast for either him or his opponent, Eric Camden?
A. Cannot be determined as samples cannot reliably be used to estimate population parameters
B. No, since the confidence interval includes values less than 50%, his opponent may get more votes
C. Yes, 52% is a majority of the votes
D. No, sampling variation causes all confidence interval conclusions to be questionable.
Using the z-distribution, it is found that the correct option regarding the question in the problem is given by:
B. No, since the confidence interval includes values less than 50%, his opponent may get more votes.
What is a confidence interval of proportions?A confidence interval of proportions is given by:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which:
[tex]\pi[/tex] is the sample proportion.z is the critical value.n is the sample size.In this problem, we have a 95% confidence level, hence[tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.
In this problem, the parameters are given as follows:
[tex]\pi = 0.52, n = 1000[/tex]
Hence, the bounds are given by:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.52 - 1.96\sqrt{\frac{0.52(0.48)}{1000}} = 0.489[/tex]
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.52 + 1.96\sqrt{\frac{0.52(0.48)}{1000}} = 0.551[/tex]
The lower bound is below 0.5, hence option B is correct.

find the measure of angle R
please help!
Answer:
68
Step-by-step explanation:
The shape is 5 sides polygon.
Sum of interior angles of a 5 sided polygon = 540,
7x + 4 + 8x + 3 + 4x + 8 + 10x - 4 + 6x + 4 = 540
7x + 8x + 4x + 10x + 6x + 4 + 3 + 8 + 4 - 4 = 540
35x + 4 + 3 + 8 = 540
35x + 15 = 540
35x = 540 - 15
35x = 525
Divide 35 on both sides,
x = 525 / 35
x = 15
Angle R = 4x + 18
Substitute the value of x,
Angle R = 4 ( 15 ) + 8
= 60 + 8
Angle R = 68

7. Find the perimeter of the rectangle with length 33 yards and width 59 yards.
A.92 yd
B.1,947 yd
C.125 yd
D.184 yd
Answer:184yards
Step-by-step explanation:
First of all, the formulae for finding the perimiter is 2xlength + 2xwidth
which can also be written as 2l + 2w
solution:
=2l + 2w
=2x33 + 2x59
=66 + 118
= 184
Therefore the perimeter of the rectangle is 184yards.

Match each inequality with the number line that represents it.
Answer:
1. x < 3
2. x ≥ 3
3. -3 > x
4. x ≤ -3
5. 3 < x
6. -3 ≤ x
Step-by-step explanation:
To find out whether the circle will be opened or closed, look at the sign. If the sign is "<" or ">", then the circle will be open. If the sign is either "≤" or "≥", then the sign will be closed.
To decide if the arrow goes right or left, again, look at the sign. If the arrow is going left, then that means x is less than whatever value the circle is at. If the arrow is going right, then x is greater than whatever value the circle is on.
Using this information, you can figure out which inequality matches each number line.
hope this helps!
