Answer:
SA=78.5
Step-by-step explanation:
Find the area to all visible sides. 4*2.5=10, 10*2 (because there is two of these shapes) is 20. 4.5*4=18, 18*2=36. Finally, 4.5*2.5=11.25, 11.25*2=22.5.
20+36+22.5=78.5
The sum of two numbers is –11. The difference of the two numbers is –7. What is the product of the two numbers?
Answers
Answer:
18
Step-by-step explanation:
According to the numbers the both numbers have to be negative
subtracting a negative will be the same as addition and so thats why the difference is bigger.
now its time for guess and check.
-6+-5
-11
but -6-(-5)=-1
so lets try
-9+(-2)=-11
-9-(-2)=-7
yay
so the product is
(-9)*(-2)=18

33.85 or 32.75 sorry if I am wrong
Step-by-step explanation:
for this one you have you multiply 17 by itself like this 17x17=289 but you also have to do it with the 28 to like this 28x28=784, now what you do it add up the 289+784=1,073 then you square root 1,073 which gives you 32.75 round it to the nearest tenth of needed so your will be between 33.85 or 32.75

Answer:
60°
Step-by-step explanation:
the relationship between angle RST and its arc TR is:
2m∠(RST)=m(arcTR);
using this formula m∠(RST)=0.5*m(arcTR);
m∠(RST)=60°
Answer:
<S = 60
Step-by-step explanation:
The arc TR and the central angle (T to the center then to R ) are equal.
So the Central angle is 120o
S anywhere on the minor arc is 1/2 the central angle.
<S = 1/2 120
<S = 60

Answers
Answer:
x = 79 y = 22

The ratio of the measures of the sides of a triangle is 3:5:7, and its perimeter is 135 feet. Find the measure of each side of the triangle.
a. x = 9
b. 13.5 ft, 22.5 ft, 31.5 ft
c. 27 ft, 45 ft, 63 ft
d. 25 ft, 45 ft, 65 ft
Answers
Answer:
The correct answer is C. 27 ft, 45 ft, 63 ft.
Step-by-step explanation:
Given that the ratio of the measures of the sides of a triangle is 3: 5: 7, and its perimeter is 135 feet, in order to find the measure of each side of the triangle, the following calculation must be performed:
3 + 5 + 7 = 15
135/15 = 9
9 x 3 = 27
9 x 5 = 45
9 x 7 = 63
Therefore, the measures of the sides of the triangle are 27 ft, 45 ft, and 63 ft.

(1, 5)Find the vertex of the function given below.
y= 2x2 + 4x + 1
Answers
Answer:
vertex is (-1,-1)
Step-by-step explanation:
2 ways
1. get into vertex form y=a(x-h)^2+k
2. use math hacks
1.
vertex is (h,k) in y=a(x-h)^2+k
complete square
y=(2x^2+4x)+1
y=2(x^2+2x)+1
y=2(x^2+2x+1-1)+1
y=2((x+1)^2-1)+1
y=2(x+1)^2-2+1
y=2(x+1)^2-1
y=2(x-(-1))^2+(-1)
vertex is (-1,-1)
2.hack way
in form y=ax^2+bx+c
x value of vvertex is -b/2a
given
y=2x^2+4x+1
b=4, a=2
xvaluevertex=-4/(2*2)
xvaluevertex=-4/4=-1
sub back to find y value
y=2(-1)^2+4(-1)+1
y=2(1)-4+1
y=2-4+1
y=-1
y value is -1
Answer:
(-1,-1)
Step-by-step explanation:
To find the x coordinate, we use the formular x = -b/2a where b=4 and a = 2 from the given function.
hence x = -(4)/2(2) = -1
then to get the y coordinate we substitute the value of x into the given function, so y = 2(-1)^2+4(-1)+1 = -1
therefore, the vertex is (-1,-1)
Christine has her own dog-walking business. She charges her customers $20 per day to walk their dog.
Make a table to show how much she earns for walking 1 to 8 dogs.
Please help me !
Answers
Answer:
Number of dogs (x) | Amount charged to walk a dog (y)
1 | 20
2 | 40
3 | 60
4 | 80
5 | 100
6 | 120
7 | 140
8 | 160
Step-by-step explanation:
Charge for walking a dog = $20 per dog
Number of dogs = x
Amount charged to walk a dog in a day = y
Unit rate = 20
Equation to represent this is: y = 20x
Let's use this to form a table for walking 1 to 8 dogs:
For 1 dog (x):
y = 20(1) = $20
For 2 dogs (x):
y = 20(2) = $40
For 3 dogs(x):
y = 20(3) = $60
For 4 dogs:
y = 20(4) = $80
And so on till we get to tl8 dogs.
This, we should have the following table:
Number of dogs (x) | Amount charged to walk a dog (y)
1 | 20
2 | 40
3 | 60
4 | 80
5 | 100
6 | 120
7 | 140
8 | 160

Describe, in words, how the figure at the right was translated.
Answers
Answer:
8 up, 6 left
Step-by-step explanation:
Locate any point from triangle A and go up 8 steps to get on the same level as triangle A'. Then, move to the left 6 steps.
The graph translated 6 unit left and 8 unit upward.
What are coordinates?A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.
Given, A figure "A" that translated at different position in cartesian plane.
Since, A translation is when a geometric figure slides up, down, left or right on the coordinate plane. The figure moves its location, but doesn't change its orientation. It also doesn't change its size or shape.
Thus, we can observe only one point on the figure and calculate the movement of the figure.
Lets focus on the left bottom corner of the figure.
It moves from the coordinates (1, -5) to the coordinates ( -5, 3)
Since Horizontally translating a graph is equivalent to shifting the base graph left or right in the direction of the x-axis
So, we can say it translated to the lefty by 6 unit.
Same it goes with vertical translation.
Therefore, The graph translated 6 unit left and 8 unit upward.

Please help this question finding a side on a triangle
Answers
Answer:
The side of the hypotenuse is 12.233 centimeters.
Step-by-step explanation:
The triangle presented in the figure represents a right triangle, we know an angle and a leg adjacent to such angle and we need to determine the length of the hypotenuse, which is found by this trigonometric relation:
[tex]\cos 56^{\circ} = \frac{7.4\,cm}{x}[/tex] (1)
Where [tex]x[/tex] is the length of the hypotenuse, measured in centimeters.
Then, we clear the variable within (1):
[tex]x = \frac{7.4\,cm}{\cos 56^{\circ}}[/tex]
[tex]x = 13.233\,cm[/tex]
The side of the hypotenuse is 12.233 centimeters.
