A baseball team won 75% of its games. If the team played 48 games, how many games did it win?
Answer: 36 games
Step-by-step explanation:
75% is 3/4
1/4 of 48 is 12, thus 3/4 of 48 is 36
Therefore, the baseball team won 36 games
What is the rule for the reflection?
ry=x(x, y) → (–y, –x)

Answer:
B
Step-by-step explanation:
Answer:
B. ry=–x(x, y) → (–y, –x)
Step-by-step explanation:

Joey, who is 6 feet tall. He stands 75 feet away from a building. He looks up at the building with an angle of elevation of 58
What is the height of the building to the nearest foot?
A
120 feet
B
126 feet
c
142 feet
D
148 teet
Answer:
the answer is A
Step-by-step explanation:
If you draw it then the height of the building (x) is the opposite, the adjacent is 75 (it's in between a 90 degree angle and the 58 degree angle). With this you have tan (58) = x/75
Then you add multiply 75 on the other side
75 tan (58) = x
After putting it in a DEG calculator, x = 120.03.
Which equation best represents the relationship between x and y in the graph?
Y=4x -2
y= 4x +8
D
Answer:
c, 4x+8 hope that helps
Héctor gastó en la entrada de cine una tercera parte del dinero con el que salió de casa. Con la cuarta parte del dinero compró una bolsa de palomitas y le sobraron 5 euros. ¿Con cuánto dinero salió de casa?
Answer:
Héctor salió de su casa con 12 euros.
Step-by-step explanation:
Cuando Héctor gastó en la entrada de cine una tercera parte del dinero con el que salió de casa, tenemos:
[tex] C = \frac{1}{3}x [/tex] (1)
Cuando compró una bolsa de palomitas con la cuarta parte:
[tex] P = \frac{1}{4}x [/tex] (2)
Entonces al sobrarle 5 euros y relacionando las ecuaciones (1) y (2) con el monto inicial:
[tex] x - C - P = 5 [/tex]
[tex] x - \frac{1}{3}x - \frac{1}{4}x = 5 [/tex]
[tex] x = 12 [/tex]
Por lo tanto, Héctor salió de su casa con 12 euros.

A school received 2 orders of new chairs. The first order contained 180 chairs. The second order contained 204 chairs. Each of the 17 classrooms received the same number of chairs. How many chairs will be put in storage as extra chairs?
Answer
10 chairs will be put in storage
Step-by-step explanation:
If you add both orders you will get 384 and divide that by 17 you will get 22.5 so 22 rounded. Multiply 22 by 17 to see the equal number of chair and you will get 374. Subtract 384 total number of chairs by 374 and you will get 10
i need this fast yal. i am willing to give brainly
Answer:
The answer is
y = 6x + 43
Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation of the parallel line we must first find the slope of the original line
The original line is y = 6x + 1
Comparing with the general equation above
Slope = 6
Since the lines are parallel their slope are also the same
Slope of parallel line = 6
The equation of the line using point (-7,1) and slope 6 is
We have the final answer as
y = 6x + 43

Answer:
Casey's Function has the greater rate of change
Step-by-step explanation:
The graph shows a ROC of 5/1
Get a common denominator (4)
5/1 * 4/4 = 20/4
20/4 > 13/4
Casey's function has a greater ROC.
Which equation corresponds to the statement, to more than a number equivalent to Y
A.y=xsquared
B. Y= x+2
C. Y= 2x
D. Y= x/2
Answer:
English statement 'two more than a number equivalent to Y' can be algebraically represented as:
y = x + 2Step-by-step explanation:
Two more than a number means we need to add 2 to a number.
Let suppose the number be = xTwo more than the number 'x' = x+2As it is stated that two more than a number equivalent to Y.Equivalent means something is equal to the given expression.
Mathematically, the 'equivalent' is represented by the symbol '='.Thus, the English statement 'two more than a number equivalent to Y' can be algebraically represented as:
y = x + 2guys i really need help!! please and thank you!!

john needs to make a total of 40 deliveries this week. So far he has completed 34 of them. what percentage of his total deliveries has john completed?
Answer
85%
Step-by-step explanation:
34/40=0.85
Answer:
85%
Step-by-step explanation:
Easy way to solve this is just to divide 34 and 40.
34÷40=0.85.
Then you multiply 0.85 by 100 to get the decimal to the front.
0.85 x 100=85
85%

What are the coordinates of the vertices of the triangle under the translation (x, y) (x + 2, y + 3)? (-4, 5), (3, 4), (0, 0) (5, -4). (4, 3), (-1, 2) (6, -5), (5, 2), (1, -1) (-5, 6), (2, 5), (-1, 1)
Answer:
(2, 5), (-5, 6) and (-1, 1)
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, dilation and translation.
If a point A(x,y) is translated a units right and b units up, the new location is at A'(x + a, y + b).
From the image attached, the location of the vertices of the triangle is at (0,2), (-7, 3) and (-3, -2). If the triangle is under the translation (x, y) ⇒ (x + 2, y + 3), the new location of the vertices would be at (2, 5), (-5, 6) and (-1, 1)
Point J (-8, -12) is reflected over the x-axis. Where is J'?
Answer:
(-8, 12)
Step-by-step explanation:
9514 1404 393
Answer:
J'(-8, 12)
Step-by-step explanation:
Reflection over the x-axis changes the sign of the y-coordinate.
(x, y) ⇒ (x, -y) . . . . . reflection over x-axis
J(-8, -12) ⇒ J'(-8, 12) . . . . reflection over x-axis

Betty had 1/3 yard of ribbon. She used 1/2 of it. How many yards of ribbon did she use?
a. 6 yd
b. 1/6 yd
c. 2/3 yd
d 3/2 yd
Answer:
b. 1/6 yd
Step-by-step explanation:
When Betty used 1/2 OF the 1/3 yards she has she has to multiple those. It's easier to put it in a sentence in my opinion because then you can see the "of" in the sentence which means to multiply. Hope this helps!
Can somebody show me the work!
Answer:
(-1,4)
Step-by-step explanation:
First lets put the two equations into y=mx+b format by subtracting 2x and 4x to the right side of their equations.
y=-2x+2
y=-4x+0
Now you can put this into a system of equations, but you can also plug in the coordinates to see if both equations are equal. I will show system of equations solution.
-2x+2=-4x, solve this by adding -2x to the right side so that the 2 is by itself.
Now you have 2=-2x. Divide by -2 to get the x by itself, now you have x=-1. Plug this back into one of the equations, so y=-4x would be y=-4(-1), so y=4.
Answer:
-1,4
hope that helps you

In the figure above, rectangle V'W'X'Y' is a dilation of rectangle VWXY. What is the scale factor of the dilation?
A. 0.25
B. 2
C. 343 fourths
D. 14
Answer:
D. [tex] \frac{1}{4} [/tex]
Step-by-step explanation:
Given that rectangle V'W'X'Y' is a dilation of rectangle VWXY, this means that the dimensions of rectangle VWXY was reduced by to get the dimensions of V'W'X'Y'.
Therefore, the ratio of any segment of V'W'X'Y', to a corresponding segment of VWXY would be equal to the scale factor.
W'X' = 5
WX = 20
Therefore:
Scale factor = [tex] \frac{5}{20} = \frac{1}{4} [/tex].
A scale factor that is a fraction tells us that the original figure reduced in size resulting into another new figure whose sides are of proportional lengths to the original figure.
In other words, the original figure was compressed go form a new figure.
