Vertical angles meet at a point of intersection and are equal. The value of x from the shown figure is 9
Vertical anglesVertical angles meet at a point of intersection and are equal.
From the figure given, the angles are vertical angles. Hence;
7x + 3 = 10x - 24
Collect like terms
7x - 10x = -24- 3
-3x = -27

How do I find the area of this?
Answer:
Area of the given right triangle = 24 square units.
Step-by-step explanation:
Given triangle in the picture is a right triangle.
Area of a right triangle is given by,
Area = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
Height of the given triangle = 8 unit
Base of the given triangle = 6 unit
Area of the triangle = [tex]\frac{1}{2}(6)(8)[/tex]
= 24 square units
Therefore, area of the given right triangle is 24 square units.

Here are the diameters of four coins. A dime rolls 41.8 cm. How many rotations did it make?
Will give brainliest,
Answer:
i believe the answer is 10.5
Step-by-step explanation:
dime = 3.14 (1.8) =5.62 cm
Since the coin rolled about 10.5 cm in 4 rotations, it means that the circumference of the coin (x) multiplied by 5 is equal to the distance rolled.
4x=41.8
x =41.8/4 =10.5cm
good luck :)

The following data points represent the number of chicken nuggets on each family member's plate.
1,3,0, 6, ?
If the mean of the data set is 3 chicken nuggets, find the missing number of chicken nuggets.
nuggets
Answer:
The missing number of chicken nuggets is 5.
Step-by-step explanation:
To find the mean of this data set, we must add every number together, then divide the sum by how many numbers are present.
Like this,
1 + 3 + 0 + 6 = 10
10 / 4 = 2.5
There are 4 present numbers in this data set, and one is missing.
Since the only number divided by 5 that would give you a quotient of 3 is 15, the missing number is 5.
Because,
1 + 3 + 0 + 6 + 5 = 15
15 / 5 = 3
Therefore, 5 is the missing number of the data set.

Answer:
A = x² + 11x + 30
Step-by-step explanation:
For a given rectangle
Length (l) = x + 5
Breadth (b) = x + 6
Now,
Area of rectangle
A = l × b
= (x + 5) × (x + 6)
= x² + 6x + 5x + 30
A = x² + 11x + 30
Thus, The area of rectangle in the form of polynomial is
x² + 11x + 30

The diameter of a bacteria species A is 1 micrometre long while bacteria B is 1 x 10^-3 the size of bacteria species A.
a) What is the diameter of bacteria species B in metres?
b) Based on your answer in (a), is the value obtained less than, greater than or equal to 1 nanometre?
Answer:
Bacteria A has diameter size of 1 micrometer = 1 × 10⁻⁶ m
a) B is 1× 10⁻³ size of A:
1 × 10⁻⁶ * 1 × 10⁻³ = 1 × 10⁻⁹ mb) 1 nanometer = 1 × 10⁻⁹ m
And bacteria B diameter size is equal to 1 nanometerPLEASE HELP IM STRESSED I CANT THANK YOU :)
Answer:
125
Step-by-step explanation:
In ΔPTO we are given that
∠PTO = 90° (indicated by the right angle)
and ∠TPO = 35°
And we need to find the exterior angle (∠TOB)
If you didn't know this is the rule about exterior angles
Exterior angles of a triangle are equal to the sum of the opposite interior angles of a triangle
So more specifically for this problem
∠TOB = ∠PTO + ∠TPO
Now that we have created an equation we want to plug in the values that we are given
∠TOB = 90 + 35
90 + 35 = 125
Therefore the answer is 125

Explanation:
you just need to find a common factor that you can divide out of each term. ex. with the 5z-10 both 5z and 10 are divisible by 5, so you can factor that out. to check the answers just multiply it. if you still don't get it, look up "factoring binomials"

Savannah had 400 chocolate chips. She saved x chips for a garnish, and mixed the rest of the chocolate chips evenly into 3 pans of brownies.
How many chocolate chips were in each pan of brownies?
Answer:
( 400-x)/3
Step-by-step explanation:
Total chocolate chips Savannah had = 400
Number of chocolate chips she saved for garnishing =x
Number of chocolate chips remain = 400-x
Number of brownie pans = 3
Chocolate chips were spread evenly in 3 pans,
Chocolate chips were in each pan of brownies =( 400-x)/3
