The inequality 10w + 40 < 450 represents the maximum number of ten-pound weights, w, a weight bench can hold if the maximum weight capacity of the bench is less than 450 pounds. The table shows the steps a trainer takes to solve the inequality.
Hey there!
10w + 40 < 450
SUBTRACT 40 to BOTH SIDES
10w + 40 - 40 < 450 - 40
SIMPLIFY IT!
10w < 450 - 40
10w < 410
DIVIDE 10 to BOTH SIDES
10w/10 < 410/10
SIMPLIFY IT!
w < 410/10
w < 41

Step-by-step explanation:
From Figure A to B, it looks like a reflection (like a mirror) (over the y-axis)
From Figure A to C, it looks like a translation (5 units down) (x - 5, y)
From Figrue A to C, it looks like a rotation

The survey included 80 students. How many students chose bananas?
Answer:
20 Students chose bananas.
Step-by-step explanation:
You can see that the bananas take up 25% or 1/4 of the chart. To find 1/4 of a number find half of the number twice. Half of 80 is 40 and half of 40 is 20. So, 20 students chose bananas.

at $26.76 per share. What is the total cost of the stocks including the commission?
Dan Hostetler purchases 2,000 shares of Ballon Synergy stock at $4.10 per share. Thus, The total cost of stock including the commission is $15917.
What are stocks?Stocks are types of security to shareholders that represent fractional ownership of equity in any organization.
Dan Hostetler purchases 2,000 shares of Ballon Synergy stock at $4.10 per share. He also purchased 500 shares of Matell Scientific at $26.76 per share.
We have a number of shares at $44.41 per share = 100
Number of shares at $19.08 per share = 600
Total number of shares = 700
Broker's charges per share = $0.04
Hence, The total cost of the stock including the commission
= Cost of stock + commission
= (100 × 44.41) + (600 × 19.08) + (700 × 0.04)
= 15,917
Thus, the total cost of stock including the commission is $15917.

Find the value of for X
(Show working out)
Answer:
[tex]x = \frac{11}{2}[/tex]
Step-by-step explanation:
4+2 (x-1)=13
⇒ 2 (x - 1) = 13 - 4
⇒ 2 (x - 1) = 9
⇒ 2 x - 2 = 9
⇒ 2 x = 9 + 2
⇒ 2 x = 11

A Diameter of a circle has endpoints P(-10, -2) and Q(4, 6)
a. Find the center of the circle.
b. find the radius. If your answer is not an integer, express in in radical form.
c. write an equation for the circle
PLS HELP FAST!
Will Give Brainiest if answered properly!
Answer:
see explanation
Step-by-step explanation:
(a)
the centre of the circle is at the midpoint of the endpoints.
using the midpoint formula
centre = ( [tex]\frac{-10+4}{2}[/tex] , [tex]\frac{-2+6}{2}[/tex] ) = ([tex]\frac{-6}{2}[/tex] , [tex]\frac{4}{2}[/tex] ) = (- 3, 2 )
(b)
the radius r is the distance from the centre to either of the endpoints
using the distance formula to find r
r = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (- 3, 2 ) and (x₂, y₂ ) = Q (4, 6 )
r = [tex]\sqrt{(4-(-3))^2+(6-2)^2}[/tex]
= [tex]\sqrt{(4+3)^2+4^2}[/tex]
= [tex]\sqrt{7^2+16}[/tex]
= [tex]\sqrt{49+16}[/tex]
= [tex]\sqrt{65}[/tex]
(c)
the equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r the radius , then
(x - (- 3) )² + (y - 2)² = ([tex]\sqrt{65}[/tex] )² , that is
(x + 3)² + (y - 2)² = 65
Answer:
Step-by-step explanation:
a) Use midpoint formula to find the center.
[tex]\sf \boxed{Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)}[/tex]
P(-10 ,-2) ⇒x₁ = -10 & y₁ = -2
Q(4,6) ⇒ x₂=4 & y₂ = 6
[tex]\sf midpoint = \left(\dfrac{-10+4}{2},\dfrac{-2+6}{2}\right)[/tex]
[tex]=\left(\dfrac{-6}{2},\dfrac{4}{2}\right)\\\\=\left(-3,2\right)[/tex]
b) To find the radius, use the distance formula
[tex]\boxed{distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}}[/tex]
Q(4,6) & O(-3,2)
[tex]r=\sqrt{(-3-4)^2+(2-6)^{2}}\\\\=\sqrt{(-7)^{2}+(-4)^2}\\\\=\sqrt{49+16}\\\\= \sqrt{65}[/tex]
radius = √65
c) Equation of circle : (x - h)² +(y -k)² = r²
Where (h,k) is the coordinates of the center and r is the radius
(x -[-3])² + (y - 2)²= (√65)²
(x + 3)² + (y -2)² = 65

wind. What was Alyssa's average speed on the round trip? Round your
answer to one decimal place.
Please help ASAP!!!
Will mark brainiest!!!!!
Answer:
533.3 mph
Step-by-step explanation:
You want the average round-trip speed if the speed to London was 480 mph and the return trip to Boston was 600 mph.
SpeedThe average speed will be the total distance divided by the total time. The time is found by dividing the distance by the speed.
If the distance is d, the total time in hours is ...
d/480 +d/600 = (3/800)d . . . . . hours
Then the average speed is ...
2d/(3/800d) = 1600/3 ≈ 533.3 . . . . miles per hour
Alyssa's average speed on the round trip was 533.3 mph.

Answer:
$3
Step-by-step explanation:
If the soda was $4 and she spent a total of $28
then you do 28-4 to get the amount she spent on candy bars so 28-4 is 24 and divide 24 by 8 and you get 3
A local weather enthusiast wants to see if the last five summers have been warmer than normal for eloy, arizona. from the national oceanic and atmospheric administration (noaa), he knows the 30-year average for july was 90° with a standard deviation of 2.1°. the last five summers recorded have an average of 93.5°. if he uses a = 5%, which of the following would be valid based on the data he has gathered? he can conclude that the summers have been warmer than the 30-year average. he can conclude that the summers will continue to be warmer for the next 10 years. he does not have enough information to make a decision. the average for the last five years fits with the 30-year average.
For the local weather of Eloy, Arizona, the average for the last five years fits with the 30-year average.
What do you mean by standard deviation?In statistics, Standard deviation is a measure of the variation of a set of values.
σ = standard deviation of a population
N = number of observations of population
X = mean
μ = population mean
The 30-year average for July was 90°. The standard deviation for this average is 2.1°. Thus, the temperature lies in the range around of 90° in July.
Therefore, the range of the temperature is,
t = 90 - 2.1 = 87.9
t = 90 + 2.1 = 92.1
The last five summers recorded have an average of 93. 5° and the value of a is 5%. Thus, the reduction is,
t = 92 - (92 x 2.5/100)
t = 89.70
This value of temperature lies in the range of 87.9-92.1 degrees Celsius. Hence, the two averages are probably the same.
Hence, for the local weather of Eloy, Arizona, the average for the last five years fits with the 30-year average. Option D is correct.

The baseball diamond at a playground is a square with sides that measure 70 feet. About how long would a straight line be from home plate to second base? Round your answer to the nearest tenth.
A baseball diamond represented by a square oriented so that the diagonal of the square running from home plate to 2nd base is vertical.
70 feet
140 feet
9,800 feet
99 feet
Answer:
70 if you walk directly across, 140 if you're running the bases
Step-by-step explanation:
So, if the distance between one is 70, than from home>first>second is 140 feet. Because it is a square, if you travel across the field from home directly to second, it is half that distance and only 70.

Suppose you take a sample of 15 pieces of colored fruit snacks and a sample of 60 pieces of colored fruit snacks from one day's production. Which sample is more likely to give you a prediction closer to the actual number of each color? Explain
Answer:
The sample of 15 pieces of colored fruit snacks
Step-by-step explanation:
The sample of 15 pieces of colored fruit snacks. The 60 pieces are from ONE day which means it can be heavily biased. It might be like "BLUE RASPBERRY SPECIAL DAY!" or "PRESIDENTS DAY!! RED BLUE AND WHITE!!". However, 15 pieces, whilst having less of a population, is probably more spaced out.

Step-by-step explanation:
using the ratio arc AC : circumference C = angle at centre of sector : 360°
[tex]\frac{AC}{C}[/tex] = [tex]\frac{123}{360}[/tex] , that is
[tex]\frac{4}{C}[/tex] = [tex]\frac{123}{360}[/tex] ( cross- multiply )
