Joan draws a bar chart to show the temperatures at midday
on March 1st in five cities.
Joan has made four mistakes
in her diagram.
Write down any three of them.
Possible mistakes in Joan's bar chart could be incorrect scale, inaccurate labeling, and inconsistent bar lengths. Correcting these errors would make the chart a more accurate representation of the temperature data.
Explanation:Without the specific bar chart, it is difficult to identify Joan's mistakes, but possible errors in a bar chart depicting temperatures could be the following:
Incorrect scale: The scale of the bar chart must correspond to the range of temperatures. For example, if temperatures vary from 15 degrees Celsius to 35 degrees Celsius, the scale should encompass this range.Incorrect labeling: Each city and corresponding temperature should be accurately labeled on the chart.Inconsistent bar lengths: The length of the bars should represent the actual data accurately. A higher temperature should have a longer bar and a lower temperature a shorter one.Learn more about Bar Chart Mistakes here:https://brainly.com/question/32121650

Before soccer practice Allyson jogs around the field that measures 100 yards by 65 yards twice. How far will she jog?
Answer:
she will jog 660
Step-by-step explanation:
(100+65)×2=1 lap
330×2=2 laps (660yards)
Final answer:
Allyson will jog around the perimeter of the soccer field twice, which totals 660 yards.
Explanation:
Allyson is jogging around a soccer field that has dimensions of 100 yards long and 65 yards wide. To find out how far she will jog, we need to calculate the perimeter of the field and then multiply it by the number of times she jogs around it.
Calculating the Perimeter:
The perimeter P of a rectangle is given by P = 2(length + width). In this case:
Length (L) = 100 yardsWidth (W) = 65 yardsSo the perimeter of the soccer field is:
P = 2(100 yards + 65 yards) = 2(165 yards) = 330 yards.
Total Distance Jogged:
Since Allyson jogs around the field twice, the total distance she will jog is:
Total Distance = Perimeter × Number of Laps = 330 yards × 2 = 660 yards.
Therefore, Allyson will jog a total distance of 660 yards.

Emily purchased a couch, loveseat, in the chair for $2000. The Loveseat cost twice as much as the chair, and the couch cost $600 more than the love seat. Find the cost of the couch, loveseat, and chair.
Answer:
Chair $280
Loveseat $560
Couch $ 1,160
Step-by-step explanation:
chair = x
loveseat=2x
couch = 2x + 600
x +2x + 2x +600 = 2000
5x + 600 =2000 subtract 600 from both sides
5x =1400 divide by 5
x = $280
Chair is the value of x =$280
Loveseat is twice the value of x = 2 x $280 =$560
Couch is twice the value of x plus $600 = $560 + $600
The cost of a chair, the cost of a loveseat, and the cost of a couch are $280, $560, and $1,160 respectively.
What is the linear system?It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
Given
Emily purchased a couch, loveseat, in the chair for $2000.
The Loveseat cost twice as much as the chair, and the couch cost $600 more than the love seat.
Let
The cost of the chair is x, then the loveseat is 2x and the cost of the couch is 2x + 600.
Then
The sum of the cost of the chair, loveseat, and couch is $2000.
[tex]x + 2x + 2x + 600 = 2000\\[/tex]
On simplifying, we have
x = 280
Then
The cost of the chair = x = $280.
The loveseat = 2x = 2(280) = $560
The cost of the couch = 2x + 600 = 2(280) + 600 = $1,160
Thus, the cost of the chair, loveseat, and couch is $280, $560, and $1,160 respectively.

O A. x = 1, y = 3
O B. x = 1, y = 5
OC. x = 3, y = 1
O D. x = 9, y = -5
Answer:
A. x=1, y=3
Step-by-step explanation:
you have to isolate y in the bottom equation in order to put it into the top equation. heres what i did:
we will start with the bottom equation, x+y=4. then, subtract x on both sides of the equation. this will isolate y. now, we have the equation; y=4-x.
next, we are going to substitute our new bottom equation in where y is on the top. it looks like this: 2x+(4-x)=5. then, we are going to get rid of the parenthesis, so our equation is: 2x+4-x=5. to solve this, we have to combine like terms, so we will combine the x terms: x+4=5. now, isolate the variable. to do this, we have to take away 4 from each side so we can get x alone: x=1.
so now that we have a value for x, we can use that to find y. we can actually substitute our x-value into the bottom equation to make it easier: 1+y=4. next, we have to isolate the variable, which is y. this gives us the final answer: y=3.

A cone shaped tepee has a radius of 4 feet and a slant height of 7feet. If joe is six feet tall, determine whether joe is shorter or taller than the height of the tepee.
Answer:
Therefore Joe is taller than the height of the tepee.
Step-by-step explanation:
Cone:
Cone is three dimensional shape. It has an vertex.Slant height of an object is a height that measured along a lateral surface from the vertex to the the base. The slant height of a cone is = [tex]\sqrt{height^2+radius^2}[/tex]The height of a cone is [tex]=\sqrt{slant\ height ^2- radius^2[/tex]The volume of a cone = [tex]\frac{1}3 \pi r^2 h[/tex]Lateral surface area is [tex]=\pi r l[/tex]
Given that,
A cone shaped tepee has a radius of 4 feet and slant height of 7 feet.
The height of the cone is [tex]=\sqrt{slant\ height ^2- radius^2[/tex]
[tex]=\sqrt{7^2-4^2}[/tex]feet
[tex]=\sqrt{33}[/tex] feet

The correct polynomial with zeros of 2, 5, and -4 is represented by Option C, which is (x - 2)(x - 5)(x + 4), even though there is a typo in the option provided.
Explanation:The zeros of a polynomial are the values for which the polynomial evaluates to zero. These are also the solutions to the equation obtained by setting the polynomial equal to zero. Given the zeros of 2, 5, and -4, we can form a polynomial by finding the factors associated with each zero and then multiplying those factors together.
The factor associated with the zero 2 is (x - 2), the factor for the zero 5 is (x - 5), and the factor for the zero -4 is (x + 4). Multiplying these factors will give us the polynomial that has these zeros:
P(x) = (x - 2)(x - 5)(x + 4).
Comparing this expression with the options provided:
Option A is incorrect because it has factors of (x + 2) and (x - 4), implying zeros of -2 and 4.Option B is incorrect because it has the factor of (2x - 4), which simplifies to (x - 2), but includes the incorrect (x + 4).Option C is correctly formed with (x - 2)(x - 5)(x + 4), despite the typo, and represents the polynomial with the given zeros.Option D is incorrect, similar to option B.Therefore, the correct answer is Option C, which is (x - 2)(x - 5)(x + 4).
