who ever answer this get a brainliest and a thank you i need it answered asap
Answer:
a = 9
Step-by-step explanation:
For solve the problem we can use the Pythagorean theorem in this way
a^2 + (3√3)^2 = (6√3)^2
If we solve the equation we have
a^2 + 27 = 108
a^2 = 81
a = +/-9
we take only the the positive value because a length can’t be negative
a = 9

How many right angles are there in an angle that turns through 360º?
4 right angles
90 + 90 + 90 + 90 = 360
However, it that figure is a circle-- it may include 0 right angles since circles have no angles.
help pleaseeee i dont get this also show work
Answer:
AC = 2
BC = [tex]2\sqrt{2}[/tex]
CD = 4
CF = 4
BD = [tex]2\sqrt{2}[/tex]
DE = 8
EF = [tex]4\sqrt{2}[/tex]
DF = [tex]4\sqrt{2}[/tex]
Step-by-step explanation:
Since all of these are isosceles triangles, it means both legs of every triangle are congruent to each other. So,
Given: AB = 2
Find:
AC = AB = 2
BC = [tex]2\sqrt{2}[/tex]
CD = 4
CF = CD = 4
BD = BC = [tex]2\sqrt{2}[/tex]
DE = 8
EF = [tex]4\sqrt{2}[/tex]
DF = EF = [tex]4\sqrt{2}[/tex]
1. Find the slant height of a square pyramid with a surface area of 57 square feet and a base perimeter of 12 feet
Answer:
Slant height = 8 feet.
Step-by-step explanation:
If the perimeter of the square base = 12 then each side of the base = 12/4
= 3 feet and its area = 3*3 = 9 ft^2
The area of one of the triangular sides = 1/2 * 3 * h where h is slant height.
So total surface area = 57 = 9 + 4 * 1.5h
9 + 6h = 57
6h = 48
h = 8 feet.

Step-by-step explanation:
Steve earned $7.40 per hour working his paper route. The first week, he worked 16 hours. After getting paid, he put $105 in the bank and spent the rest on rides at the carnival. Each ride cost $0.75. How many rides did Steve ride at the carnival?
Answer:17
Step-by-step explanation: Multiply Steve’s hourly wage ($7.40) by the hours he worked in a week (16 Hours) that would give you your weekly earnings which would be (7.40x16=$118.40) Then subtract what he saved in the bank from your total (118.40-105=$13.40) then you would divide $13.40 (his leftover money) by $0.75 to find the total number of carnival rides he could ride (13.40/0.75=17.86 rides and because he cannot ride 17 and 86 hundredths of a ride he would be able to ride 17 carnival rides.

Which equation best represents the data in the function table
Answer:
y = x² + 1
Step-by-step explanation:
y = x² + 1
When x = -3
y = -3² + 1
y = 9 + 1 = 10
When x = -1
y = x² + 1
y = -1² + 1
y = 1 + 1 = 2
When x = 0
y = x² + 1
y = 0² + 1 = 1
When x = 2
y = x² + 1
y = 2² + 1
y = 4 + 1 = 5
All of the x and y values have been correct
Answer:
A
Step-by-step explanation:
the others will not produce the correct value for the image ((y)), if you replace the incognito x in the equation by the -3, you can see that you only obtain the result 10 for y in the first equation. you don't even need to test all the cases.

Oliver has created a plot of his backyard on the given coordinate plane, so that each unit length is one yard. He wants to design a right triangular plant bed for his backyard that has an area of eight square yards. After placing one vertex of the base of the plant bed at (3, 8) and one vertex at (7, 8) on his coordinate plane, he has to determine where to place the last vertex. Locate the possible locations of the last vertex on the coordinate plane.
Answer:
The possible locations are;
(3, 4), (3, 12), (7, 4), and (7, 12)
Please find attached the plot of the points created with Microsoft Excel
Step-by-step explanation:
The given parameters of the plot of Oliver's backyard are;
The area of the right triangular plant bed Oliver wants to design, A = 8 yd²
The length of a/each unit of the plot = 1 yard
The location of one of the vertex of the right triangular area = (3, 8)
The location of the other vertex of the right triangular area = (7, 8)
We note that the area of a triangle, A = 1/2 × Base length, B × Height, h
Let the distance between the two plotted point represent the base length, 'B', therefore;
B = 7 - 3 = 4 (We subtract only the x-values (7 and 3) given that the y-values (8 and 8) are the same;
Therefore, the base length, B = 4 yards
A = 1/2 × B × h
∴ A = 8 yd.² = 1/2 × 4 yd. × h
h = 8 yd.²/ 2 yd. = 4 yd.
The height of the right triangle, h = 4 yd.
Therefore the possible locations of the last vertex the right triangle on the coordinate plane, given that the first two points are parallel with the x-axis, are points 4 units above or the y-axis value of the plotted points with the x-value of the last vertex being either 3, or 7 as follows;
(3, 8 ± 4) or (7, 8 ± 4) which give points, (3, 4), (3, 12), (7, 4), and (7, 12).

Hence, [tex]\sqrt{131}[/tex] is in between 11 and 12
Solve the system by substitution.
x = 9y
x-5y=20
Step-by-step explanation:
hope this helps you! have a great day
The solutions of the system of equations are x = 45 and y = 5.
What is the system of equations?One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.
Given:
The system of equations,
x = 9y .... (1)
x-5y=20 ......(2)
Substituting the value of x from the equation 1 to equation 2,
we get,
9y - 5y = 20
4y = 20
y = 5
Then, x = 5(9) = 45
Therefore, the solutions of the equations are x = 45 and y = 5

A. x=-10
B. x=-4
C. x=7
D. x=-7
E. x=10
Answer:
B. x = -4
E. x = 10
Step-by-step explanation:
[tex](x-3)^2=49 \\ \\ x - 3 = \pm \sqrt{49} \\ \\ x - 3 = \pm 7 \\ \\ x = 3 \pm 7 \\ \\ x = 3 + 7, \: \: x = 3 - 7, \\ \\ x = 10, \: \: x = - 4[/tex]
