What is the length of the hypotenuse of the triangle below?
Answers
Answer:
D
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
The square oh the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
h² = (9[tex]\sqrt{2}[/tex] )² + (9[tex]\sqrt{2}[/tex] )² = 162 + 162 = 324 ( take the square root of both sides )
h = [tex]\sqrt{324}[/tex] = 18 → D
A fair dice is rolled 3 times in a row. The outcomes are shown below. Calculate the probability of all three events occurring. Roll Outcome 1st 5 2nd factor of 6 3rd more than 1
Answers
Answer:
5/54
Step-by-step explanation:
probability of the dice being 5 = 1/6
probability of the dice being a factor of 6 = 4/6
probability of the dice being more than 1 = 5/6
1/6 * 4/6 = 4/36
4/36 * 5/6 = 20/216
20/216 simplified to lowest is equal to 5/54
Find the sum of the interior angles of a quadrilateral with 15 sides?
Answers
Answer:
2340°
Step-by-step explanation:
To find the sum of interior angles of any shape, use the formula: 180(n - 2), where n is how many sides there are. So,
180(15 - 2)
180(13)
2340
Answer:
2,340
Step-by-step explanation:
Using Formula
=> [tex](n-2)*180[/tex]
Where n is the number of sides. Here, no. of sides is 15
=> [tex](15-2)*180[/tex]
=> [tex]13*180[/tex]
=> 2,340
f(x)= 2x^2 + 5x - 17, find f(-1).
Answers
Answer:
-20
Step-by-step explanation:
f(x)= 2x^2 + 5x - 17,
f(-1)
Let x = -1
f(-1)= 2 *(-1)^2 + 5(-1) - 17
= 2 *1 -5 -17
= 2 -22
= -20
Answer:
-20
Step-by-step explanation:
f(x)= 2x² + 5x - 17
Put x as -1.
f(-1)= 2(-1)² + 5(-1) - 17
Solve for the powers.
f(-1)= 2(1) + 5(-1) - 17
Multiply the terms.
f(-1)= 2 + -5 - 17
Add or subtract the terms.
f(-1)= -20

Which function is represented by the graph?
Answers
Answer:
Step-by-step explanation:
An absolute value function has the standard form
where h and k are the coordinates of the vertex (the pointy part of the graph) and the absolute value of a indicates whether or not the graph is the same width as the parent graph or if it is steeper or flatter. If the absolute value of a is greater than 1, the graph is steeper; if the absolute value of a is greater than 0 but less than 1 (in other words a fraction less than 1), the graph is flatter than the parent. If the graph is upside down, there will be a negative out in front of the absolute value of a. Because our graph is in fact upside down, we will choose one of the options that has a negative in front of it. The fact that it has moved UP from the origin, but not side to side, means that the k value is a +1.
If you are familiar with an absolute value parent graph, the lines go through each diagonal of the grid perfectly. It appears that our graph is steeper (or slimmer) than that. That means that not only is our graph upside down, it also has an a value greater than 1. Putting those 2 facts to use along with our k value of +1, makes our obvious choice the first one listed.

Answer:
Step-by-step explanation:
4) In ΔABD & ΔBAC
AD = BC {given}
∠DAB = ∠CBA {given}
AB = AB {Common to both triangles}
ΔABD ≅ ΔBAC { Side Angle Side - SAS congruent}
b) BD = AC { Corresponding Part of congruent trianlge}
5) (i)In ΔDMB & ΔAMC
M is midpoint of AB
MA = MB
∠DMB =∠AMC {Vertically opposite angles}
CM = DM {Given}
ΔDMB ≅ ΔAMC ( Side Angle Side - SAS congruent}
(ii) ∠DBM = ∠ACM {CPCT}
Alternate angles are equal. Therefore, BD // AC
BD // AC & BC transversal
Co interior angles are 180
∠DBC + ∠ACB = 180
∠DBC + 90 = 180
∠DBC = 180 - 90
∠DBC = 90 , ∠DBC is right angle.
(iii)In ΔDBC & ΔACB
BD = AC { CPCT form Proof (i)}
∠DBC = ∠ACB = 90 {from Proof (ii)}
BC = BC {common}
ΔDBC ≅ ΔACB { SAS Congruent}
(iv) CD = AB
C is midpoint of CD
CD = 2CM
2CM = AB
CM =(1/2)AB

I NEED HELP ASAP Which equation is equivalent to: −10r−6=115
A. 10r=−115+6
B. −10r=115+6
C. −10r=115−6
D. 10r=115−6
Answers
B is the right answer to this question because you have to change the operator
The equation is equivalent to −10r−6 = 115 will be B. -10r = 115 + 6.
What is a system of equations?
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
The equation is equivalent to −10r−6 = 115
Add 6 on both side;
−10r−6 = 115
−10r−6 + 6 = 115 + 6
-10r = 115 + 6
Hence, the equation is equivalent to −10r−6 = 115 will be B. -10r = 115 + 6.

A thirty-five ounce bottle of Pedialyte contains 2,500 mg of dextrose. If a child drinks 7 ounces straight from the bottle, how many mg of dextrose will he consume?
Answers
Answer:
500 mg
Step-by-step explanation:
amount of dextrose in 35 ounce Pedialyte = 2500 mg
dividing LHS and RHS by 35
amount of dextrose in 35/35 ounce Pedialyte = 2500 /35 mg = 500/7 mg
Thus,
amount of dextrose in 1 ounce Pedialyte = 500 /7 mg
since we have to find amount of dextrose in 7 ounce Pedialyte
we multiply LHS and RHS by 7
Thus,
amount of dextrose in 1 *7 ounce Pedialyte = 500 /7 * 7 mg = 500 mg
amount of dextrose in 7 ounce Pedialyte = 500 mg
Thus, As child consumed 7 ounces of Pedialyte, He consumed 500 mg of dextrose.

Answers
Answer:
Statement 1: True
Statement 2: True
Statement 3: False
Statement 4: False
Step-by-step explanation:
First of all, Statement 1 is that the domain is [0, 10]. Domain is how far the graph goes from left to right. So from 0, it goes to 10.
Second, the range is determined by how far the graph goes from down to up. This is determined by each points on the line, (3, 7, 9, 12)
Third, Statement 3 is false because it ends at (10, 12)
Fourth, a function cannot be curved, If the vertical line you drew intersects the graph more than once for any value of x then the graph is not a function. From point (0, 3) to (4, 7) is curved and not straight.

Answer:
Step-by-step explanation:
Locate the 1 on the x axis. This is one hour worked. Go up vertically along x = 1 and you "land" on the red line very quickly. If you go straight across to the left, you are at 14 on the y-axis. The y-axis indicates the amount of money Leo earns tutoring. If he works one hour and earns $14 and this is a straight line (linear function with a constant slope), that means that for every hour he works he will earn $14. Locate the 2 on the x-axis and go up x = 2 til you hit the red line. Read it to the left and you "land" on the y-axis at $28. $28 divided by 2 hours of work is $14 per hour of tutoring. The first choice is the one you want.

First find the time Adrian takes to get to school
I found it easiesT to use the method of ratio and proportion
40:60
16:x
x= 16 x 60 / 40 = 24 minutes
So, he has 60-24 minutes to return home, that is 36
What is his speed if his time is 36 minutes= 0.6 hours
Speed = Distance divided by time = 16/0.6 = 26.6 miles per hour.

Find the area of the rectangle.
Answers
Answer:
D. 96 in²
Step-by-step explanation:
Each triangle is congruent to the others, so each has a side length of 8 and a hypotenuse of 10. The unknown side can be found from the Pythagorean theorem to be ...
width = √(10² -8²) = √36 = 6
Then the area of the rectangle is ...
area = length × width = (2·8 in)(6 in) = 96 in²
The area of the rectangle is 96 square inches.
