50 points the answer isnt 30 so dont say it is because it isnt
Answer:
its 25.
Step-by-step explanation:because 50 divided by 2 is 25.
Answer:
40 units
Step-by-step explanation:
1) Find the side length of the square
Let the side be "s".
[tex]\rightarrow \frac{1}{2} \times s \times s = 50 \ \text{cm}^{2}[/tex]
[tex]\rightarrow s \times s = 50 \times 2[/tex]
[tex]\rightarrow s \times s = 100[/tex]
[tex]\rightarrow \sqrt{s \times s} = \sqrt{100}[/tex]
[tex]\rightarrow s = \±10[/tex]
[tex]\rightarrow s = 10 \ \text{units}[/tex] (Side lengths can never be negative)
2) Find the perimeter of the square
[tex]\text{Perimeter of square = 4(s) = 4(10) = 40 units}[/tex]

what is the answer to the equation -7x-3x+2= -8x - 8
Answer:
x=5
Step-by-step explanation:
-7x-3x+2= -8x - 8
Add like terms
-7x-3x=-10x
-10x+2=-8x-8
+8x +8x
-2x+2=-8
-2 -2
-2x=-10
Divide by -2 to isolate the variable
x=5
Answer:
x = 5Step-by-step explanation:
what is the answer to the equation
-7x - 3x + 2= -8x - 8
-7x - 3x + 8x = -10
2x = -10
x = 5
----------------------
check
-7 * 5 - 3 * 5 + 2 = -8 * 5 - 8
-48 = -48

A donut shop made 50 donuts. They put frosting on 2 of the donuts. What is the ratio of the
number of donuts with frosting to the number of donuts without frosting?
50:48

Submit
Answer:
50-2
Step-by-step explanation:
there is 50 donuts and 2 that are frosted :)
Step-by-step explanation:
2 have frosting, therefore 50-2 = 48 don't.
so, the ratio is for frosting vs. non-frosting
2 : 48 (which would be also 1 : 24).
find the values of x and y ????
show step plz
Answer:
x= 90 degrees
y= 47 degrees
Step-by-step explanation:
Since the two sides of this triangle are equal in lengths, you know that it is an isosceles triangle.
So with this information, you know that the angle at the bottom left is also 47 degrees.
x would be equal to 90 degrees because it is perpendicular to the bottom of the triangle (assuming).
A triangle has 180 degrees, so add up the lengths we have to solve for the missing angle, y.
90+47+y=180
y= 43
[tex]{\huge{\boxed{\mathfrak{Answer\:With\:Explanation}}}[/tex]
First we can say [tex]x=90[/tex]°, since x is located at the right angle part.
Now we can make an equation
[tex]90+47+y=180[/tex]
subtract 137 from sides.
[tex]y=43[/tex]

a triangle with side 9,10and 11 has the same perimeter as a square with sides of length
Answer:
7.5.
Step-by-step explanation:
A square has 4 equal sides so:
4x = 9 + 10 + 11 where x is the length of one side of the square.
4x = 30
x = 7.5.

Question 16
What is the shortest distance between the line y = 2x+4 and the point at (0.0)? Round to the nearest tenth.
O A) 1.8
O B) 2.0
O C) 3.2
O D) 4.0
The shortest distance between the line y = 2x+4 and the point at (0.0) is 1.8 units option (A) is correct.
What is a straight line?A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
It is given that:
The equation of the line is:
y = 2x + 4
Or
2x - y + 4 = 0
The point is (0, 0)
As we know, the formula for the shortest distance between the line and a point:
D = |ax + bx + c|/√(a²+b²)
Plug x = 0 and y = 0
a = 2, b = -1, and c = 4
D = |2(0) + -1(0) + 4|/√(2²+(-1)²)
D = 4/√5
D = 1,78 ≈ 1.8 units
Thus, the shortest distance between the line y = 2x+4 and the point at (0.0) is 1.8 units option (A) is correct.

6. Find the average rate of change of Pete's height from 3 years
old to 5 years old.
Choices:
o 2 inches per year
o 4 inches per year
O 8 inches per year
Answer:
The Answer is "4 inches per year"
Step-by-step explanation:
To find the Average Rate of Change, you use:
[tex]\frac{y_{2} -y_{1}}{x_{2} -x_{1}}[/tex]
So when you insert the numbers from the table, you get:
[tex]\frac{45-37}{5-3}[/tex]
After solving the answer you get is 4. So the avg rate of change is 4 inches per year.

SAS
SSA
ASA
SSS
Answer:
Step-by-step explanation:
△ RST ≅ △ TXY
We are given ΔRST and ΔTXY are congruent to each other.
If two triangles are congruent to each other then their corresponding parts are equal.
Please see the attachment of two triangles.
∠R is corresponding to ∠T
∵ ∠R=∠T By CPCT
∠XYT is corresponding to ∠STR
∵ ∠XYT=∠STR By CPCT
∠XTY is corresponding to ∠SRT.
∵ ∠XTY=∠SRT By CPCT
∠TXY is corresponding to ∠RST
∵ ∠TXY=∠RST By CPCT
CPCT: Congruent part of congruence triangle.
