Answer:
-17 or b
Step-by-step explanation:
b = 4(-3) - 5
b = -12 - 5
b = -17
when a = -3 c is -20
- 17 is larger. you may think "oh its 20 that must be larger!" but thats wrong. -17 you be larger because its closer to 0

Step-by-step explanation:
To find the median, arrange the data in ascending order
10,20,30,40,50,60,70,80,90
Number of data = 9 . It is a odd number
So, median will be the (n+1)/2 th term
[tex]\left(\dfrac{9+1}{2} \right)^{th \ term} = (\dfrac{10}{2})^{th \ term} = 5^{th \ term}[/tex]
Median = 50
Solution:
Step-1: Re-arrange the following data from biggest to smallest.
30, 10, 40, 20, 60, 50, 80, 70, 90=> 90, 80, 70, 60, 50, 40, 30, 20, 10Step-2: Refer to the following:
1. If there is an even number of digits, you will use the formula:
(Total number of digits)/22. If there is an odd number of digits, you will use the formula:
(Total number of digits + 1)/2Step-3: Find the median:
If we count the number of digits in the data, we can say that nine numbers are in this data. Thus, we will use the formula "(Total number of digits + 1)/2"
=> (Total number of digits + 1)/2 term=> (9 + 1)/2 term=> 10/2 term=> 5th termThe fifth term of the group is the median.
Step-4: Review the "biggest to smallest" data.
90, 80, 70, 60, 50, 40, 30, 20, 10Since 50 is the 5th term, the median is 50.

Distribute
-7(x+10)=7(5-x)
-7x-70=7(5-x)
Distribute
-7x-70 = 35-7x → Answer for the attachment "35"
Add 70 to both sides of the equation
-7x-70+70=-7x+35+70
Simplify
-7x=-7x+105
Add 7x to both sides of the equation
-7x+7x=-7x+105+7x

Hello! In this question, we will be plugging in values to fit the simplification process of the expression.
__________________________________________________________
Explanation:
We were given the expression: -7(x + 10) = 7(5 - x)
In order to simplify the expression, we would use the distributive property.
Solve:
-7(x + 10) = 7(5 - x)
Distribute the "7" to the terms inside the parenthesis (x + 10).
-7x + (-70) = 7(5 - x)
Distribute the other "7" to the terms inside the parenthesis (5 - x).
7x + (-70) = 35 - 7x
Since we are only looking for the values in the simplification process, the answer for the first box would be -70 and the second box would be 35.

An element with mass 590 grams decays by 19. 5% per minute. How much of the element is remaining after 15 minutes, to the nearest 10th of a gram?
Answer:
Step 1
Formulate a recursive sequence modeling the number of grams after n minutes.
we have that
100%-17.1%-------------- > 82.9%------------> 0.829
a(n) = 780*[0.829^n]
for n=19 minutes
a(19)=780*[0.829^(19)]=22.1121 g---------------> 22.1 g
the answer is 22.1 g

Leroy is a citizen scientist for a monarch butterfly project. Every week, he visits a local patch of milkweed and counts the number of monarch larvae on the plants. Last week, Leroy didn't count many larvae. This week, he counts 29 larvae on the milkweed. For both weeks, Leroy's total count is 41 larvae. Which equation can you use to find the number of larvae n Leroy counted last week?
Answer:
12 larave
Step-by-step explanation:
41 - 29
If Leroy's total count is 41 larvae. The number of larvae n Leroy counted last week will be 12.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
It is given that, Leroy didn't count many larvae. This week, he counts 29 larvae on the milkweed. For both weeks, Leroy's total count is 41 larvae.
We have to apply the subtraction operation, subtraction is defined as the difference between two quantities. The application of subtraction can be used broadly in different applications to find or solve the problems such as finding differences between two quantities and many more.
Total count = count for this week + count for last week
41 = 29 + count for last week
count for last week = 41 - 29
count for last week = 12
Thus, If Leroy's total count is 41 larvae. The number of larvae n Leroy counted last week will be 12.

pls help tyyy!!!!!!!!!
Part A
For this part, I'm assuming your teacher implies that we ignore the door, windows and rectangular opening. It seems like parts B and C cover this aspect.
There are 2 walls that are 20 feet by 10 feet. Each is 20*10 = 200 sq ft, so both opposite walls are 2*200 = 400 sq ft.
Then there are 2 more walls that are 15 ft by 10 ft. Each has area 15*10 = 150 sq ft, and doubles to 2*150 = 300 sq ft.
The total wall area (ignoring any openings/doors/windows/etc) is 400+300 = 700 sq ft.
Another way to get this answer is to find the perimeter of the floor rectangle to get 2(L+W) = 2(20+15) = 2(35) = 70. Then multiply this with the height of the room to get 70*10 = 700
Answer: 700 square feetNote: This ignores the windows/doors/any other opening
====================================================
Part B
Useful info to focus on:
Fact1: Along one of the long walls, there are three windows that each measure 3 feet by 8 feetFact2: Along one of the short walls, there are two windows that each measure 3 feet by 8 feet.Fact3: Along the other long wall, there is a rectangular opening that measures 7 feet by 8 feet.There's no mention of a door (either front door or interior door to another room). Instead, your teacher talks about a rectangular opening which I'm assuming is the walkway to perhaps the kitchen and/or hallway or something. Though this rectangular opening might be part of or entirely the front door. It's not clear what your teacher means here. I'll just forget about the door part.
Fact1 and fact2 tell us we have 3+2 = 5 windows of 3 ft by 8 ft. Each window has area 3*8 = 24 sq ft. Five of them give 5*24 = 120 sq ft
Fact 3 says we have a rectangular opening of area 7*8 = 56 sq ft.
The total area of all items mentioned is 120+56 = 176 sq ft
Answer: 176 sq ft====================================================
Part C
We subtract the results of the previous parts A and B
wall area to paint = A - B = 700 - 176 = 524 sq ft
We're told that "The cans of paint Kamrie will purchase cover 415 square feet." So we'll divide the total area over the area per can.
524/415 = 1.26265 which is approximate
Round up to the nearest whole number. We don't round down to 1 can because we'll come up short. Instead we round to 2 paint cans. Having extra leftover paint is handy in case Kamrie made a mistake somewhere.
For this entire problem, I'm ignoring the ceiling and focusing on the walls only.

Answer:
These triangles cannot be proved congruent
Step-by-step explanation:
The theorems for congruence are SSS SAS ASA AAS. Here, there is only one common side and one common angle marked, therefore you cannot prove congruency.
Answer: They are congruent
Step-by-step explanation:
The side marks are marked as 1, so they are equal. You can try moving the second triangle on the first, but what you can also do is use the law of cosines using a random side and angle value to find if the other sides are equivalent.

The diameter of a circle is 19 cm.
Find its circumference in terms of Pi
Step-by-step explanation:
just apply the formula.
the circumference of a circle is
C = 2 × pi × r
r = radius = diameter / 2
in our case r = 9.5 cm (19/2)
so, the circumference is
C = 2 × pi × 9.5 = 19 × pi

1. A television is on sale for $1.200, which is a 40% discount of the regular price.
What is the regular price of the television?
A. $2.200
B. $1.900 C. $1,800 D. $2.100 E. $2.000
say the regular price is "x", which is the 100% of the value, and we know it's discounted by 40%, so that means 100% - 40% = 60%, and we know as well that that value is 1200, so.
[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} x&100\\ 1200&60 \end{array}\implies \cfrac{x}{1200}=\cfrac{100}{60}\implies \cfrac{x}{1200}=\cfrac{5}{3} \\\\\\ 3x=6000\implies x=\cfrac{6000}{3}\implies x=2000[/tex]

Find the Area of the figure below, composed of a rectangle with a semicircle removed from it. Round to the nearest tenths place.
Answer:
62.9 square units
Step-by-step explanation:
The area of a composite shape is the sum of the areas of the parts. Here the shape consists of a positive rectangle that has dimensions 8 × 11, together with a negative half circle of radius 8/2 = 4. That is, the area of the half-circle is subtracted from the area of the rectangle, as the problem statement tells you.
__
Rectangle areaThe area of a rectangle is the product of its dimensions:
A = LW = (11)(8) = 88 . . . . square units
Semicircle areaThe area of a semicircle is half the area of a circle, so will be given by the formula ...
A = 1/2πr^2 = 1/2π(4^2) = 8π ≈ 25.1 . . . . square units
Total areaThe area of the figure shown is the difference between the rectangle area and the semicircle area:
total area = rectangle area - semicircle area
total area = 88 -25.1 = 62.9 . . . . square units
