Answer:
B 15
Step-by-step explanation:
Answer:
15 is correct
Step-by-step explanation:
given the angles are the same we can write it as:
4x-30 =2x
-30=-2x
15=x
with the strategy of writing same angles as an equation, you can solve these math problems hopefully easily yourself.

Can predictions be made of a scatterplot that shows no association? Explain your answer.
Answer:
There is no relationship between the variables.
There is no pattern between the variables.
No reliable predictions are possible.
Step-by-step explanation:
this is the exact answer on edge 2021
Answer:
No, because no association means there is no relationship between the variables. So there is no pattern that results in reliable predictions.

An initial population of 325 quail increases at an annual rate of 11%. Write an exponential function to model the quail population. Group of answer choices
Answer:
f(x) = 325*1.11ˣStep-by-step explanation:
Initial population = 325Increase rate = 11% or 0.11Required function is:
f(x) = 325(1 + 0.11)ˣ f(x) = 325*1.11ˣJames drew a scaled version of Triangle J using a scale factor of 4 and labeled it Triangle K. The base of triangle J is 5 units and the height of triangle J is 4. What is the area of triangle K?
Answer:
160
Step-by-step explanation:
If the scale factor is 4, we would have to multiply the height and width by 4
4*5=20
4*4=16
Now to find the area of the triangle using the formula (20*16)/2
That equals to 160
The base of a triangle is twice the height of the triangle.
The area of a triangle is 16 cm.
Draw the triangle on a centimetre grid.
(2 marks)
Answer:
4cmStep-by-step explanation:
[tex]area = \frac{1}{2} \times base \times height \\ 16 {cm}^{2} = \frac{1}{2} \times 2x \times x \\ 16 {cm}^{2} = \frac{2 {x}^{2} }{2} \\ \\ 16 {cm}^{2} \times 2 = 2 {x}^{2} \\ 32 {cm}^{2} = 2 {x}^{2} \\ \frac{32 {cm}^{2} }{2} = {x}^{2} \\ 16 {cm}^{2} = {x}^{2} \\ \sqrt{16 {cm}^{2} } = \sqrt{ {x}^{2} } \\ 4cm = x \\ [/tex]

Step-by-step explanation:
Line JK passes through points J(–3, 11) and K(1, –3). What is the equation of line JK in standard form?
7x + 2y = –1
7x + 2y = 1
14x + 4y = –1
14x + 4y = 1
Answer:
7x + 2y = 1
Step-by-step explanation:
First we find the slope m of the line
The slope of a line that passes through 2 points x1, y1 and x2 , y2 is given as
m = (y2 - y1)/(x2 - x1)
Considering the points (–3, 11) and K(1, –3), the slope of the line m
= (-3-11)/(1 --3)
= -14/4
= 7/2
the line JK may be given as
y - 11 = -7/2(x - -3)
multiply through the equation by 2
2y - 22 = -7(x + 3)
2y - 22 = -7x - 21
7x + 2y = 22 - 21
7x + 2y = 1
Answer:
B
Step-by-step explanation:
7x + 2y = 1

Rick is facing east.He makes three-quarters of complete turn clockwise.Which direction is Rick now facing?
Answer: directly north
=============================================
Explanation:
A one quarter turn is 1/4 of 360 degrees, so it's (1/4)*360 = 90 degrees.
Three quarters of a full turn is (3/4)*360 = 270, or you could triple the 90 to get 90*3 = 270.
Rick starts facing directly east. Then he rotates 270 degrees clockwise to end up facing directly north. Refer to the diagram below.

someone plzz helpp mee !
show full working outs
i only have 15mins to finish this assignment
Answer:
area=54
perimeter=30
Step-by-step explanation:
add all the sides=p
multiply 6 and 3 then 6 and 6 and add them together=a
Answer:
perimeter = a+b+c+d+e+f+g
= 6 +3+2+6+6+2+3= 28
area=first of all find the area one by one
area of the lying rectangle is.
a=l×b
but first let's add 3+3 =6
b=6
a=6×6
a=36
area of the standing rectangle
a=l×b
let's add 6+6=12 &2+2=4
a=l×b
a=12×4=48
then let's add both area together
36+48=84
therefore perimeter is 28 and area is 84
Step-by-step explanation:
why is double 6 is because the length are the same.
Find the surface area.
1 m
10 m
Answer:
[tex]A=69.11\ m^2[/tex]
Step-by-step explanation:
Given that,
The radius of cylinder, r = 1m
Height of the cylinder, h = 10 m
We need to find the surface area of the cylinder. The total surface area of a cylinder is given by :
[tex]A=2\pi r^2+2\pi rh\\\\A=2\pi r(r+h)[/tex]
Put all the values,
[tex]A=2\pi \times 1(1+10)\\\\=69.11\ m^2[/tex]
So, the surface area of the cylinder is equal to [tex]69.11\ m^2[/tex].
PLEASE HELP. !!!!!!!!!
Answer:
(-1,8)
Step-by-step explanation:
use formula
A(x,y) = A'(-y , -x)
coordinate point is
(-8,1)=(-1,8)
therefore the image of the (-8,1) after a reflection over the line y=-x is (-1,8)
Answer:
A'(-1,8)
Step-by-step explanation:
Initial point A(-8,1)
reflection about y=-x has the rule
x, y -> (-y, -x)
So
A(-8,1) -> A'(-1,8)

write short note on the rules on how to bisect a line
Answer:
here the answer is
If u want nore help please follow
Step-by-step explanation:
STEP 1: Draw a straight line with a ruler. STEP 2: Put the pin of a compass at the end of the line you want to bisect. Set the compass to more than half the length of the line, and draw an arc crossing the line. STEP 3: Keep the width of the compass the same, and from the opposite end of the line draw another arc.
Answer:
First, in your compass take more than half of the given line, i.e, if the line is 5 centimeters, then in the compass take a length more than five centimeters.
Second, Draw an arc, by keeping the compass needle on one end of the line, and do the same by keeping it on the other end.
Two of the arcs will intersect at a point.
Third, do the same, but in the back-ward direction, as in the below of the line. These two will also intersect.
Lastly, draw a line connecting the intersection of the top and below arcs.
I couldnt add the last pic because of the 5 attachments rule. Like I said in the last rule, just join the two arc intersections.
Thank You
Hope u understood
Joe's lunch at a restaurant costs $13.00 without tax. He leaves the waiter a tip of 17% of the cost of the lunch, without tax. What is the total cost of the lunch, including the tips, without tax?
Answer: $15.21
Step-by-step explanation:
Given
Joe's lunch cost $13.00 without tax
He tipped the waiter with 17% of bill without tax
So, the amount of tip is
[tex]\Rightarrow 13\times 17\%\\\Rightarrow 13\times 0.17\\\Rightarrow \$2.21[/tex]
Total amount that food costs without tax is
[tex]\Rightarrow 13+2.21\\\Rightarrow \$15.21[/tex]

What is the value of x?
Answer:
29
Step-by-step explanation:
The right triangle is isosceles triangle so we have the left angle of it is:
180-64=116
116÷2=58
Then start to calculate the left triangle angles:
180-58 = 122
180-122 = 58
58÷2 = 29
a right triangle has legs of lengths 6 and 3, what is the length of the hypotenuse to the nearest tenth
Answer:
x = 6.7
Step-by-step explanation:
legs of a right triangle are 6,3 and hypotenuse be x
using pythagors theorem to find hypotenuse
a^2 + b^2 = c^2
6^2 + 3^3 = x^2
36 + 9 = x^2
45 = x^2
[tex]\sqrt{45} = x[/tex]
[tex]\sqrt{3*3*5} = x[/tex]
[tex]3\sqrt{5} = x[/tex]
6.70 =x
6.7 =x

Peng bought 19 stationary bikes for $748 each. How much did she soend on stationary bike? Write an expression with the solution
Answer:[tex]\$ 14,212[/tex]
Step-by-step explanation:
Given
Peng bought 19 stationary bikes for $748 each
The cost of 19 bikes is the multiplication of the cost of each bike times the total bikes
[tex]\Rightarrow \text{Cost= }19\times 748\\\\\Rightarrow \text{Cost= }\$ 14,212[/tex]
Thus, she spends [tex]\$ 14,212[/tex] on 19 bikes.
