Answer:
{-3, 5}.
Step-by-step explanation:
y = x + 8
x + y = 2
Substitute y = x + 8 in the second equation:
x + x + 8 = 2
2x + 8 = 2
2x = -6
x = -3
Now plug this into the first equation
y = -3 + 8 = 5.

HHHHHHHHHHHHHELLLLLPPPPPPP ME PLS PLS PLS a school wants to add a new sports team. The school sent out surveys asking for the students' favorite sport. seventeen students named swimming. Others named hockey or volleyball . Use pencil and paper. Explain how to use the circle graph and ratios to find the number of students surveyed. Then find this number.
Answer:
Total 100% or 25 students
Swimming 36% or 9 students
Lacrosse 48% or 12 students
Volleyball 16% or 4 students
Step-by-step explanation:
To do a circle graph, you draw a circle and divide it into all sections.
To know the size of each section, you need to know the total number of every category.
You could draw it with percent.
100% is total, and you know the percent of each sport.
They told you 12 students choose lacrosse so, this represents 48%.
Now, you can find the other numbers with cross-multiplication.
48%____12
100%____X=
X=(100x12)/48=25
Total students: 25
Students that named lacrosse: 12 or 48%
100%____25
16%____X=
X=(16x25)/100=4
Students that named Volleyball: 4 or 16%
100%____25
36%____X=
X=(36x25)/100=9
Students that named Swimming: 9 or 36%
To confirm: 12 + 9 + 4 = 25

What is the length of DE?
1 unit
3 units
4.5 units
4 2/3 units
Answer:
DE=4
Step-by-step explanation:
got it right on edg
The length of DE is given as: 3 Units. (Option B)
A line that joins two points on a curve is called a Secant Line.
What is the Secant Theorem?
Two secant theorem states that if two secant lines are drawn from a point outside a circle a relationship is formed between the line segments.
How do we arrive at the length of DE?Based on the Secant Theorem, from the figure, we know that:
AX * BX = EX * DX
Assuming that the length of DE equals X,:
AX * BX = EX * DX
Equals
(7+2) X (2) = (x + 3) (3)
To solve for x we expand the brackets to state:
9 * 2= 3x + 9
3x = 18-9
3x= 9
x = 9/3
X which is same as DE = 3 Units.

Answer:
16.39
Step-by-step explanation:
volume of sphere = (4/3) · 3.14(π) · r³
=> 2304 = 4/3 · 3.14 · r³
=> 2304 · 3/4 = 3.14 · r³
=> 1,728 = 3.14 · r³
=> r³ = 550.318
=> r = 8.19
diameter = 2 · r
=> diameter = 2 · 8.19 = 16.39

Need help with all the question
Answer:
Step-by-step explanation:
So in ratios you can mostly all of the time scale your answer. So by determining how much increase there is in the baby's thigh bone each week you can pretty much answer these questions.
keep in mind: Proportional means having the same ratio. A scale factor is the ratio of the model measurement to the actual measurement in simplest form.
Example from https://www.mathsisfun.com/numbers/ratio.html
A ratio says how much of one thing there is compared to another thing.
ratio 3:1
There are 3 blue squares to 1 yellow square
Ratios can be shown in different ways:
Use the ":" to separate the values: 3 : 1
Or we can use the word "to": 3 to 1
Or write it like a fraction: 31
A ratio can be scaled up:
ratio 3:1 is also 6:2
Here the ratio is also 3 blue squares to 1 yellow square,
even though there are more squares.
