Answer:
(-10, 10) or (-10, -10)
Step-by-step explanation:
[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2[/tex]
[tex]15 = \sqrt{(-10 - 1)^2 + (y_2 -2 )^2}[/tex]
[tex]15 = \sqrt{121 + 2y + y^2 + 4}[/tex]
[tex](15)^{2} =( \sqrt{121 + 2y + y^2 + 4})^{2}[/tex]
[tex]225 = 121 + 2y + y^2 + 4[/tex]
[tex]225 = 125 + 2y + y^2[/tex]
[tex]0 = -100 + 2y + y^2[/tex]
[tex]0 = (y + 10)(y - 10)[/tex]
The probability of randomly selecting two oranges from a bowl of 5 oranges and 4 tangerines if the first selection is replaced
Answer:
25/81
Step-by-step explanation:
The probability of randomly selecting two oranges = (number of oranges in the bowl / total number of fruits in the bowl) x (number of oranges in the bowl / total number of fruits in the bowl)
total number of fruits in the bowl = 5 + 4 = 9
5/9 x 5/9 = 25/81
Simplify.
(2 x 108) + (4 * 103)

Alfonso plans to create an ice sculpture out of a 8-cubic foot ice cube. What is the surface area of the cube?
Answer:
Surface area of cube = 24 ft²
Step-by-step explanation:
Given:
Volume of cube = 8 ft³
Find:
Surface area of cube
Computation:
Volume of cube = Side³
Side³ = 8 ft³
Side³ = (2 ft)³
Side = 2 ft
Surface area of cube = 6a²
Surface area of cube = 6(2)²
Surface area of cube = 6(4)
Surface area of cube = 24 ft²
The area of a rectangle is 560 square inches. The length is 3 more twice the width. Find the length and width.
Answer:
l = 35 inches and b = 16 inches
Step-by-step explanation:
Let length be b and width be b.
The area of a rectangle is 560 square inches.
Length is 3 more twice the width.
l = 2b+3 ....(1)
We know that,
Area = length × width
560 = (2b+3)b
[tex]2b^2+3b-560=0\\\\b=16,-17.5[/tex]
Put b = 16 in equation (1).
l = 2(16)+3
= 35 inches
So, the length is 35 inches and the width is 16 inches.

The manager of The Counter noticed that the birthday club members all brought along a family member who spent an average of $22.00 in the restaurant. The tax on their bill was 9 percent. How much did the family member pay in total? (Hint: bill total + tax)
Answer:
Total amount pay by family member = $23.98
Step-by-step explanation:
Given:
Average amount spent on food = $22
Tax rate on restaurant food = 9%
Find:
Total amount pay by family member
Computation:
Amount of tax pay by family member = Average amount spent on food x Tax rate on restaurant food
Amount of tax pay by family member = 22 x 9%
Amount of tax pay by family member = 22 x 0.09
Amount of tax pay by family member = $1.98
Total amount pay by family member = Average amount spent on food + Amount of tax pay by family member
Total amount pay by family member = 22 + 1.98
Total amount pay by family member = $23.98
What’s the answer????
can somebody help with this??????
Answer:
6
Step-by-step explanation:
The equation can be made more clear by changing the form.
g(h(0)) = ?
All we have to do is find the y values for an x value of 0
h(x) = x^2 - 3
h(0) = 0^2 - 3
h(0) = -3
So now we plug in -3 for g(x)
g(x) = -2x
g(-3) = -2(-3)
g(-3) = 6
A cylinder with the height of 6km has a volume of 384km3 what is the radius?
Answer:
r = 8
Step-by-step explanation:
V = π r^2 h so 383 = r^2 (6)
383 / 6 = r^2
64 = r^2 so
r = 8
what expression is equivalent to -5(x)+(-4)(-3)
Answer:-25+-12

Answer:
Properties of a parallelogram
Opposite sides and opposite angles are congruentAdjacent angles are supplementary (sum to 180°)Diagonals bisect each other#1
17 = x + 3 ⇒ x = 17 - 3 ⇒ x = 14y - 2 = 38 ⇒ y = 38 + 2 ⇒ y = 40#2
a + 5 = 15 ⇒ a = 15 - 5 ⇒ a = 103b = 111° ⇒ b = 111°/3 ⇒ b = 37°#3
2u = 124° ⇒ u = 124°/2 ⇒ u = 62°124° + v - 3 = 180° ⇒ v + 121° = 180 ⇒ v = 180° - 121° ⇒ v = 59°#4

In order to get this answer, we must know that a triangle's angles add up to exactly 180. Also, Angles that intersect will have congruent, opposite sides. The last thing is that a line is = 180 degrees. So, the triangle with the 94 and the 142, you can use that. the angle next to the 142 is going to be 180-142 which is 38 and since the other angle is opposite 94, as well. when you add those up u get 132 and 180-132= 48 which is the missing angle for the far right triangle. then, you get the opposite of that angle, put that in the other triangle, do the same with the 72, and add those up to get 120 and since a triagle adds up to 180, 180-120 = 60. So, 60 is your missing angle. Cheers
