Annita is sewing a lace edge around a rectangular quilt. She will need 146 inches of lace to do the entire quilt. If the quilt is 38 inches wide, how long is the quilt?
Answer:
35 inches long
Step-by-step explanation:
the answer is 35 inches long because if you do 38x2 because of the two sides you will get 76 then subtract 76 from 146 then you will get 70. Then do 70÷2 to find out the other side and i got 35

Drag each tile to the correct box. Johnny has a bag full of letter tiles. He picks one tile and then replaces it. He’s checking to see how many times he picks the letter A. Arrange the following situations, starting with the situation that gives the largest difference between relative frequency and actual probability and ending with the situation that gives the smallest difference. Johnny performs the experiment 75 times. Johnny performs the experiment 50 times. Johnny performs the experiment 20 times. Johnny performs the experiment 32 times. , , ,
Based on the number of times Johnny performs the experiment, the order from the largest difference in relative frequency and actual prob. to the smallest is:
The difference between absolute probability and relative frequency will be larger if the number of experiments performed is smaller.
This is why the largest difference was seen when Johnny performed the experiment 20 times and the smallest difference was seen when the experiment was done 75 times.

of cardboard. It is 13 m
long, 7 m wide and 3 m high. How much cardboard
le needed to build the box?
Step-by-step explanation:
Length of a shipping box (L) = 13m
breadth of a shipping box (b) = 7m
height of a shipping box (h) = 3m
Now,
Volume of a shipping box (v) = L*b*h
= 13*7*3

Jeremy drew a quadrilateral. Each angle in his quadrilateral was congruent to its opposite angle. Which of these could not be the name of Jeremy's quadrilateral?
a. parallelogram
b. rectangle
c. rhombus
d. trapezoid
Answer:
I think it is the rectangle
Step-by-step explanation:
I wish it is really helpful for u
Answer: D. Trapezoid
Step-by-step explanation:
From the question, it tells us that each angle was congruent to its opposite angle, since in a rectangle all angles are 90 degrees, rectangles won’t be correct. Parallelograms is self explanatory. Rhombuses have 2 pairs of same angles, which only leads to a trapezoid with 2 different bases, leading to different angles in it’s opposite corner.

Answer:
22.21
Step-by-step explanation:
The slope of a linear function is calculated by rearranging the equation to its general form, f(x) = mx + c; where m is the slope. The vertex of a quadratic function is calculated by rearranging the equation to its general form, f(x) = a(x – h)2 + k; where (h, k) is the vertex.

Median
The measure of central tendency of a distribution of data that can take multiple value is the mode
How to determine the measure of central tendency?In a given dataset;
The range is the difference between the least and the highest data elementThe mean is the average valueThe median is the middle valueAll the above measures can take only one value in a dataset
However, the mode can take multiple values, because it represents the data element with the highest frequency (and multiple data elements can have the same frequency)

Evan drops a ball vertically from a height of 150 ft. The peak height after each bounce is half the previous height. How many feet does the ball travel from the time he drops the ball until it reaches the peak height after the 6th bounce? Show all steps used to find the solution.
Answer:
442.96875 ft.
Step-by-step explanation:
Original Height (h) : 150 ft
Bounce 1 (h₁) : h/2 = 150/2 = 75 ft
Bounce 2 (h₂) : h₁/2 = 75/2 = 37.5 ft
Bounce 3 (h₃) : h₂/2 = 37.5/2 = 18.75 ft
Bounce 4 (h₄) : h₃/2 = 18.75/2 = 9.375 ft
Bounce 5 (h₅) : h₄/2 = 9.375/2 = 4.6875 ft
Bounce 6 (h₆) : h₅/2 = 4.6875/2 = 2.34375 ft
Finding the sum of bounces 1 - 5 :
75 + 37.5 + 18.75 + 9.375 + 4.6875 112.5 + 18.75 + 9.375 + 4.6875131.25 + 9.375 + 4.6875140.625 + 4.6875145.3125 ftDistance traveled :
Original Height + 2 x Sum of Bounces (1 - 5) + Height of 6th bounce150 + 2 x 145.3125 + 2.34375150 + 290.625 + 2.34375440.625 + 2.34375442.96875 ft.
Answer:
442.96875 ft
Step-by-step explanation:
We can model the height of each bounce as a geometric series.
General form of a geometric sequence: [tex]a_n=ar^{n-1}[/tex]
(where [tex]a[/tex] is the initial term and [tex]r[/tex] is the common ratio)
If we let n be the number of bounces, then the initial term has to be:
[tex]a_1=\dfrac12(150)=75[/tex]
since this is the height of the ball after the first bounce.
The common ratio r has already been given to us, as we have been told that the height of the bounce halves after each bounce.
[tex]\implies r=\dfrac12=0.5[/tex]
Therefore, the geometric series to model the peak height of each bounce is:
[tex]a_n=75(0.5)^{n-1}[/tex]
(where [tex]a_n[/tex] is the height and n is the number of bounces)
Therefore, to calculate the total number of feet the ball travels until it reaches the peak height of the 6th bounce:
Total = 150 + (2 × sum of 1, 2, 3, 4 & 5th bounces) + 6th bounce
To find the sum, use the geometric sum formula:
[tex]S_n=\dfrac{a(1-r^n)}{1-r}[/tex]
Therefore, the sum of the bounces 1 through 5 is:
[tex]\implies S_5=\dfrac{75(1-0.5^5)}{1-0.5}=145.3125[/tex]
Height of the 6th bounce:
[tex]\implies a_6=75(0.5)^{6-1}=2.34375[/tex]
[tex]\begin{aligned}\textsf{Total distance} & =150+2\left(\dfrac{75(1-0.5^5)}{1-0.5}\right)+75(0.5)^{6-1}\\ & = 150 + 2(145.3125)+2.34375\\ & = 150 + 290.625+2.34375\\ & =442.96875\: \sf ft \end{aligned}[/tex]

A flour moth trap has the shape of a triangular prism that is open on both ends. An environmentally safe chemical draws the moth inside the prism, which is lined with an adhesive. What is the surface area of the prism-shaped trap?
Answer:
72 in²
Step-by-step explanation:
since the trap is open left and right, we don't include these side areas.
so, all we have for the surface area are
the top rectangle (2.5 in × 12 in),
the bottom rectangle (2 in × 12 in)
the back rectangle (1.5 in × 12 in)
for the total surface area we need to to add all 3 areas up.
in our case we get
2.5 × 12 = 30 in²
2 × 12 = 24 in²
1.5 × 12 = 18 in²
total is then
30 + 24 + 18 = 72 in²

Select two ratios that have the same unit rate as 2:4
A. 1:3
B. 1:2
C. 3:5
D. 5:10
E.4:6
F. 6: 10
Answer:
B and D
Step-by-step explanation:
2:4 when divided by 2 gets you 1:2
and 2:4 multiplied by 2.5 gets you 5:10
Answer:
B and D
Step-by-step explanation:
So basically we have to find the unit rate of 2:4.
(remember to find the unit rate we have to simplfy the ratio until one of the quantities is 1)
2:4 (divide by 2 on each side)
1:2 (B)
now we can use this unit rate of 1:2 to find out other equal ratios
1:2 (multiply 5 on both sides)
5:10 (D)

Answer:
(a) 5 units up
(b) 3 units right
(c) 7 units left
Step-by-step explanation:
Parent equation: [tex]y=x^2[/tex]
Transformed equation: [tex]y = (x - h)^2+ k[/tex]
h translates the parabola horizontally
If h > 0 then the translation is h units to the right.
If h < 0 then the translation is h units to the left.
If h = 0 then there is no horizontal translation.
k translates the parabola vertically
If k > 0 then the translation is k units up.
If k < 0 then the translation is k units down.
If k = 0 then there is no vertical translation.
Part (a)
Given equation: [tex]y=x^2+5[/tex]
Rewriting in transformed equation form: [tex]y=(x-0)^2+5[/tex]
Therefore, the parabola is translated 5 units up.
Part (b)
Given equation: [tex]y=(x-3)^2[/tex]
Rewriting in transformed equation form: [tex]y=(x-3)^2+0[/tex]
Therefore, the parabola is translated 3 units right.
Part (c)
Given equation: [tex]y=(x+7)^2[/tex]
Rewriting in transformed equation form: [tex]y=(x+7)^2+0[/tex]
Therefore, the parabola is translated 7 units left.
Part (d)
Given equation: unreadable

Henry opened his account with a starting amount of $920, and he is going to take out $60 per month. Write an expression for the amount of money in Henry’s account after x months.
$920 - $60x
Step-by-step explanation:
after one month, he try would have taken out 60 x 1 dollars, after two months, 60 x 2, 3 months, 60 x 3, etc. so after x months he would have taken out 60x (60 times x) dollars. if he starts with 920 dollars, he would be left with $920 - $60x.
