Answer:
Step-by-step explanation:
h+n=14, n=14-h
2h+3n=34, using n=14-h
2h+3(14-h)=34
2h+42-3h=34
-h+42=34
-h=-8
h=8, and since n=14-h
n=14-8=6 so
They bought 8 hotdogs and 6 nachos.
Right triangle ABC is shown below.
A similar right triangle would be created by a rise of 8 and a run of
Answer:
a run of 6
Explanation:
AB=4 , AC=3
If you create a rise of 8 you doubled the rise of AB [4x2], so you would double the run of AC as well [3x2] = 6

Find the volume of the triangular prism. Please give an explanation if you can!
Answer:
9x14=126
63x8=1008
1008x.5=504cm
Step-by-step explanation:
Remember the formula for calculating volume is: Volume = Area by height. V = A X h.
For a triangle the area is calculated using the formula: Area = half of base by altitude. A = 0.5 X b X a.
So to calculate the volume of a triangular prism, the formula is: V = 0.5 X b X a X h.
Lara and Mae participated in a quiz contest. They scored 23 points in all. If Lara scored 9 points, how many points did Mae score?
Answer:
14
Step-by-step explanation:
23-9=14 if Lara only scored 9 points, Mae would have had to get the rest so you have to subtract 9 from the total amount of points.

Alex swims 20 minutes per day for exercise. The total
number of minutes m she swims equals 20 times the
number of days d she swims.
What is the independent variable. The Dependent Variable. And the Equation.
Answer:
e total number of minutes, m.
Step-by-step explanation:
The dependent variable is the variable in which the variable cannot stand by itself.
In this situation, the total number of minutes, m, equal 20 times the number of d.
m = 20d
d, is a variable which can be multiplied which states that it has a value, no matter what. On the other hand, m, requires d, to be there in order to have a value.
The answer is, m, the total number of minutes.

Which of the following statements are true?
I. All rectangles are squares.
II. All squares are rectangles.
III. Some quadrilaterals are rectangles.
Answer: the III
Step-by-step explanation: because rectangles are a type of quadrilaterals
Answer:
The answer is Some quadrilaterals are rectangles.
Step-by-step explanation:
A rectangle is a parallelogram with four right angles, so all rectangles are also parallelograms and quadrilaterals. On the other hand, not all quadrilaterals and parallelograms are rectangles. A rectangle has all the properties of a parallelogram, plus the following: The diagonals are congruent.
Use the diagram to determine which is the correct net of the given figure. Then, explain why the other nets are not correct--explain what is "wrong" with them.
Answer:
C is the correct answer.
Step-by-step explanation:
That is the correct one because C has 6 pages, as many has the cuboid has. As we see, the others are different.
A ladder that is 13 feet long leans against a building .The bottom of the ladder is 5 feeet away from the base of the building .how far up the side of the building does the ladder reach?
Length of the ladder = 13 m
Foot of the ladder from the wall = 5 m.
The upper end of the ladder is (13^2–5^2)^0.5 = 12 m above the ground.
In 1 second the foot of the ladder is 7 m from the wall, while the top end is (13^2–7^2)^0.5 = (169–49)^0.5 = 120^0.5 = 10.95 m. Then the top moves 1.05 m downwards.
In 2 seconds, the foot of the ladder is 9 m from the wall, while the top end is (13^2–9^2)^0.5 = (169–81)^0.5 = 88^0.5 = 9.38 m. Then the top moves 3.62 m downwards.
In 3 seconds, the foot of the ladder is 11 m from the wall, while the top end is (13^2–11^2)^0.5 = (169–121)^0.5 = 48^0.5 or 6.93 m. Then the top moves 6.07 m downwards.
So, if the foot of the ladder moves at a constant rate of 2 m/s the top end of the ladder moves downwards which varies from second to second.Answer: The lader will form the hypotenuse. Length of hypotenuse = 13m.
Let us take the horizontal distance between the wall and the ladder as ‘ground’. This g = 5m
wall ^ 2 + ground ^ 2 = 13^2 = 169
w^2 + g^2 = 169
w^2 + 25 = 169. Thus, w^2 = 144. Thus, w = 12
Rate of change of ground distance = dg / dt = 2m/s (given).
In the equation w^2 + g^2 = 169, differentiate the equation with respect to time.
2 w dw/dt + 2 g dg/dt = 0
2 (12) (dw/dt) + 2 (5) (2) = 0. So, 24 dw/dt + 20 = 0
dw/dt = -20 / 24 = -5 / 6
Thus, the height of the wall is decreasing at a rate of -5/6 m / s (that is, -0.833m/s)
The minus sign denotes that the height of the ladder is falling.

The diameter of the circle shown below is 12 m. What is the area of the circle?
Answer:
36pi meters squared
Step-by-step explanation:
The area of a square is calculated using the formula "pi(r)^2" To find the radius (r), we divide the diameter by 2 (12/2=6). We know that the radius is six and 6^2 = 36. The last step is to multiply by pi.
What is the center and radius of this circle? And how do I find it

Find the area of the figure in yards squared.
Answer:
370.1946711 yard ^2
Step-by-step explanation:
The figure is made out of two shapes, a square and a semicircle.
area of a circle is pi r^{2}
but in this question we have half of the cirlce therefore = 0.5 pi r^{2}
area of square = s * s
that makes the equation:
0.5* pi * (12)^{2} + 12^{2}
= 360.1946711
You go for a run on Monday.You ran 1.23 km.On Tuesday you run the same distance. How far did you run altogether.
Consider a circle whose equation is x2 + y2 – 2x – 8 = 0. Which statements are true? Select three options.
The radius of the circle is 3 units.
The center of the circle lies on the x-axis.
The center of the circle lies on the y-axis.
The standard form of the equation is (x – 1)² + y² = 3.
The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.
Answer:
The first, second, and fifth statements are correct.
Step-by-step explanation:
We are given a circle with the equation:
[tex]x^2+y^2-2x-8=0[/tex]
And we want to select the statements that are true.
First, we can convert the equation into standard form. We can group each variable:
[tex](x^2-2x)+(y^2)=8[/tex]
And complete the square for the first term:
[tex](x^2-2x+1)+(y^2)=8+1[/tex]
Factor and simplify:
[tex](x-1)^2+y^2=9[/tex]
We can rewrite our equation as:
[tex](x-(1))^2+(y-(0))^2=(3)^2[/tex]
So, this tells us that we have a circle centered on (1, 0) with a radius of 3 units.
In this case, the first statement, second statement (the point (1,0) is on the x-axis), and fifth statements are correct (the square root of 9 is also 3).
Answer:
The first, second, and fifth statements are correct.
