solve each equation
Hint: y < 10
7y + 7 = 56.
42 - 6y = 6,
(y + 1){2} = 9,
1 + 72/y = 10,
Answer:
1. y = 7
2. y = 6
3. y = 7/2
4. y = 8
Step-by-step explanation:
I searched it up and found the answer.
Let's solve each equation one by one :
7y + 7 = 56➝ 7y + 7 = 56
➝ 7y = 56 - 7
➝ 7y = 49
➝ y = 49 / 7
➝ y = 7
42 - 6y = 6➝ 42 - 6y = 6
➝ - 6y = 6 - 42
➝ - 6y = - 36
➝ y = -36 / - 6
➝ y = 6
( y + 1 )² = 9➝ ( y + 1 )² = 9
➝ y + 1 = √ 9
➝ y + 1 = 3
➝ y = 3 - 1
➝ y = 2
1 + 72 / y = 10➝ 1 + 72 / y = 10
➝ 72 / y = 10 - 1
➝ 72 / y = 9
➝ 72 = 9y
➝ 9y = 72
➝ y = 72 / 9
➝ y = 8

Identify the vertical cross section of the cylinder.
A). rectangle
B). circle
C). oval
D). triangle
Answer:
Rectangle
Step-by-step explanation:
if you split the shape in half vertically you won't get a circle, oval, and triangle isn't even anywhere in that picture.
so using the process of elimination it would have to be the first option. Rectangle.
AAH SOMEBODY HELP ME
Answer:
D
Step-by-step explanation:
Area of figure
= area of triangle +area of rectangle
Area of triangle
= ½ ×base ×height
= ½(6)(3.5)
= 10.5 ft²
Area of rectangle
= length ×breadth
= 6(4.6)
= 27.6 ft²
Area of figure
= 10.5 +27.6
= 38.1 ft²
Thus, option D is correct.
38.1 square feet
===============================================
Work Shown:
area of triangle = base*height/2 = 6*3.5/2 = 10.5
area of rectangle = base*height = 6*4.6 = 27.6
total area = triangle + rectangle = 10.5+27.6 = 38.1 square feet

PLS HELP!!! The snowy tree cricket is sometimes called the temperature cricket because the frequency of its chirps varies based on the temperature. The number of snowy tree cricket chirps per minute is 148 less than 4 times the outside temperature in degrees Fahrenheit. The equation x=4f-148 relates the number of chirps per minute x and the outside temperature in degrees Fahrenheit f. What is the change in chirps per minute for each increase in temperature by 1 degree Fahrenheit? Explain your answer.
Answer:
Step-by-step explanation:
62 degrees Fahrenheit
Step-by-step explanation:
The number of snowy tree cricket chirps per minute is 148 less than 4 times the outside temperature in degrees Fahrenheit.
Let x = number of chirps
f = temp in Fahrenheit
x = 4f -148
Now let x = 100
100 = 4f-148
Add 148 to each side
100+148 = 4f-148+148
248 = 4f
Divide each side by 4
248/4 = 4f/4
62=f
The changes in chirps per minute for each increase in temperature by 1 degree Fahrenheit will be 252.
What is the equation?An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.
It is given that, a snowy tree cricket makes 148 chirps per minute, which is less than four times the ambient temperature in Fahrenheit.
x=4f-148
Suppose x,f be the number of chirps and temperature in Fahrenheit
x = 4× 1 -148
Suppose the number of chirps is 100.
x = 4(100)-148
x =400 - 148
x = 252
100+148 = 4f-148+148
248 = 4f
f =248 / 4
f = 62
Thus, the changes in chirps per minute for each increase in temperature by 1 degree Fahrenheit will be 252.

Answer choices:

D. 60
Answer:
22 millimeters
Step-by-step explanation:
Firstly, to find the median of a box and whisker plot, you find the center line of the plot and look to which number on the line it is pointing to. Median = middle, to help you remember.For the diameter of bicycle tires, the median appears to be 585 millimeters, as it is exactly halfway between 580 and 590.For the diameter of automobile tires, the center line is on 840 millimeters.The question is asking for the difference of the medians between the bike tires and the automobile tires. You would subtract 840 from 585 to find this. This will get us 255.Now we find the ranges of both graphs. The range is subtracting the largest graphed number from the smallest. For bike tires, the range is 621 - 559, which is 62. I am unclear if the person who created the graph intended for the end lines to be one number off. If not, then it would be 60.The range for automobile tires would be 881 - 821, which equals 60.The question asks for "how many times the difference between the medians of both automobile and bike tires is the range of the bike tires." This is asking us to subtract the combined medians of the graphs to the range of bike tires.First, we need to add both medians together. This would be 585 + 840, which equals 1,425. Next, we subtract the range of bike tires, 62, from 1,425. This equals 1,363.The question asks how many times the difference is. To find how many times 62 goes into 1,363, we need to divide. 1,363 ÷ 62 = 21.98, which rounds up to 22.If I am incorrect in my reasoning, please let me know so that I can plan better for my future answers. Have an amazing day.
