Answer:
x=-4 y=-7
Step-by-step explanation:
-4x+y=9 get y alone
add 4x both sides
y=4x+9
insert into y=2x+1
2x+1=4x+9
subtract 1 both sides
2x=4x+8
subtract 4x both sides
-2x=8
divide by -2
x=-4
y=2x+1
y=2(-4)+1
y=-8+1
y=-7
check
-4(-4)+(-7)=9
-16+(-7)=9
9=9
x=-4
y=-7

1.96
7.85
94.2
282.6
1,130.4
Answer:
282.6
Step-by-step explanation:
v=pi r^2 h =3.14x9x10
since diameter is 0.5 feet then it is equal to 6 inch so diveided by 2 give 3 as radius and square 3 give 9 so 3.14x9x10 = 282.74 which 282.6 is the closees answer

Work out the circumference of this circle.
Take it to be 3.142 and give your answer to 1 decimal place.
4 cm
Answer:
circumference=2\pi r
25.12cm
Step-by-step explanation:
hope this helps
The required circumference of the given circle is 25.12 cm as shown figure.
What is the Circumference of a circle?The Circumference of a circle is defined as the product of the diameter of the circle and pi.
C = πd
where 'd' is the diameter of the circle
We have been given data as follows:
The radius of the circle (r) = 4 cm
Circumference of the circle = 2πr
Substitute the values in the above formula and we get
Circumference of the circle = 2π(4)
Circumference of the circle = 3.14(8) = 25.12 cm
The required circumference of the given circle is 25.12 cm.

im new can anyone help
Answer:
We have the equation:
[tex]W = W_0*(\frac{1}{2})^{0.36*t}[/tex]
Where:
W₀ is the initial area of the wound, and t is the time in days.
Now, if we initially have a wound of 25 mm^2, then:
W₀ = 25mm^2
And we can replace it in the equation, then we get:
[tex]W = (25mm^2)*(\frac{1}{2})^{0.36*t}[/tex]
We want to know the size of this wound after:
a) 1 day.
We know that t represents time in days, so here we just need to replace t by one, then:
[tex]W = (25mm^2)*(\frac{1}{2})^{0.36*1} = 19.5 mm^2[/tex]
b) 1 week
Again, t represents the time in days, so we need to write this in days.
We know that:
1 week = 7 days.
then t = 7
The size of the wound after 7 days is:
[tex]W = (25mm^2)*(\frac{1}{2})^{0.36*7} = 4.36 mm^2[/tex]
Adia is placing soil in flower pots. She has 58 quart of soil. She needs 54 quarts of soil to fill one whole flower pot. Use the drop-down menus to complete the statements below about the flower pots that Adia can fill with the soil she has.
Answer:
1 whole flower pot
Step-by-step explanation:
Given that:
Quart of soil Adia has = 58
Quart of soil to fill a whole flower pot = 54
The pot Adia can fill. With the soil he has :
Quart of soil Adia has / Quart of soil to fill a whole flower pot
= 58 / 54
= 1.074 pots
= 1 flower pot

If x + 15 = 30, what is the value of 2(x – 5)?
PLEASE ANSWER TODAY!!!
Answer:
Answer is 20
Step-by-step explanation:
X+15=30
30-15= 15 so that means 15+15=30
2(x-5) X is 15 so 15-5=10 then multiply by 2.
The required value of 2(x – 5) is 20 when the equation is x + 15 = 30.
What is an equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
The equation is given in the question, as follows
x + 15 = 30
First, we can solve for x by subtracting 15 from both sides of the equation:
x + 15 - 15 = 30 - 15
x = 15
Next, we can substitute this value of x into 2(x – 5):
2(x – 5) = 2(15 – 5)
2(x – 5) = 2(10)
2(x – 5) = 20
Therefore, the value of 2(x – 5) is 20.

3x-y=0
2x+y=-10
Answer:
(-2, -6)
Step-by-step explanation:
Given the simultaneous equation
3x-y=0 ... 1
2x+y=-10 ... 2
Add both equations to eliminate y
3x + 2x = 0 - 10
5x = -10
x = -10/5
x = -2
Substitute x = -2 into 1
3(-2)- y = 0
-6 - y = 0
-y = 0+ 6
-y = 6
y = -6
Hence the coordinate (x, y) is (-2, -6)
