Answer:
No, they cannot both be right
Step-by-step explanation:
Firstly, we need to convert the ft in the real room to inches
Mathematically; 1 foot = 12 inches
So 15 ft will be 15 * 12 = 180 inches
18 ft will be 18 * 12 = 216 inches
Now let’s look at their drawings;
9 to 10.8
So 9 translated to 180 while 10.8 translated to 216
So the ratios here are;
9/180 and 10.8/216 = 1 : 20 for the ratio of the drawing to the real measure
This shows that only Ricky is right
the cost price of a box and a pen is rupees 80 the box is sold at 10% profit and the pen is sold at 10% loss if the selling price of the box is rupees 28 more than that of the pen calculate the profit or loss percent in the whole
2.5%
Step-by-step explanation:[tex]if\ the\ art-rice\ of\ pen\ is\ x\\ so\ the\ toux\ is\ 8v-x\\ then\ (80-x)\bullet1\bullet1-a9\bulletx=28\\ so\ x=30.\\ So\ the\ selling\ price\ of\ box\ is\ RS.5\\ the\ selling\ price\ of\ pen\ is\ R527\\ R55+R_27=R8.2\\ so\ profit\ percent=\frac{R882-R830}{280-}\times100\ percent=2.5\ percent\\ (figure\ out\ their\ individual\ oosts)[/tex]

The measure of c is ???
(30PTS and PLEASE HELP!!) What is the function rule that describes the pattern in the table?
X: -2, -1, 0, 2, 1
Y: -6, -5, -4, -3, -2
A. x = y - 4
B. y = x + 4
C. y = x - 4
D. x = y + 4
9514 1404 393
Answer:
C. y = x - 4
Step-by-step explanation:
We notice that values of x are consistently 4 more than the corresponding values of y. One way this can be written is ...
x = y + 4 . . . (matches choice D)
However, we usually consider y to be the dependent variable. Rearranging this to "y = " form, we have ...
y = x - 4 . . . matches choice C
Which inequality is equivalent to −y<7?
A). Y < 7
B). Y > 7
C). Y > -7
D). Y < -7
Answer:
C) Y > -7
-Y < 7 given
0 < 7 + Y add Y to both sides
-7 < Y subtract 7 from both sides
In parallelogram EFGH, what is the relationship between angle e and angle f?
e° = f°
e° + f° = 180°
e° = -f°
e° - f° = 180°
Answer:
=> e° + f° = 180°
Step-by-step explanation:
we know. that this is a parallelogram .
e° + f° = 180° { because they are adjacent angle and the sum of adjacent angles in a parallelogram is 180°}
Answer:the answer is e° + f° = 180°

Write out the steps to find the solutions for the following quadratic: (x-2)^2 = 25
(Please help me out with this one!)
Answer:
x=7
Step-by-step explanation:
Starting with (x-2)² = 25
First, square root both sides to get rid of the square on the left. You'll get:
x-2 = 5
Add 2 to both sides to get x alone. You'll get:
x=7
Check your answer by filling in 7 for x:
(7-2)² = 25
(5)² = 25
25 = 25

Triangle XYZ has vertices X(8, −2.3), Y(6.5, 5), and Z(6, 3). When translated, X′ has coordinates (3.8, −0.3). Enter a rule to describe this transformation. Then find the coordinates of Y′ and Z′. Drag and drop each number into the correct box to complete the statements. The rule is (x, y) arrowright parenleftzex − , y + parenrightze. The coordinates are Y′parenleftze, parenrightze and Z′parenleftze, parenrightze.
Answer:
The coordinates of [tex]Y'(x,y)[/tex] and [tex]Z'(x,y)[/tex] are [tex]Y'(x,y) = (2.3, 7)[/tex] and [tex]Z'(x,y) = (1.8, 5)[/tex], respectively.
Step-by-step explanation:
A translation is a geometrical operation consisting in moving a point a given distance. We proceed to describe the operation:
[tex]X(x,y) +U(x,y) = X'(x,y)[/tex] (Eq. 1)
Where:
[tex]X(x, y)[/tex] - Initial point on the cartesian plane, dimensionless.
[tex]X'(x, y)[/tex] - Translated point on the cartesian plane, dimensionless.
[tex]U(x, y)[/tex] - Translation component, dimensionless.
Vectorially speaking, we find that translation component is:
[tex]U(x, y) = X'(x,y) -X(x,y)[/tex]
If we know that [tex]X(x,y) = (8, -2.3)[/tex] and [tex]X'(x,y) = (3.8, -0.3)[/tex], the translation component is:
[tex]U(x,y) = (3.8,-0.3)-(8,-2.3)[/tex]
[tex]U(x,y) = (3.8-8, -0.3+2.3)[/tex]
[tex]U(x,y) = (-4.2, 2)[/tex]
Now we determine the coordinates of [tex]Y'(x,y)[/tex] and [tex]Z'(x,y)[/tex]:
([tex]Y(x,y) = (6.5, 5)[/tex], [tex]Z(x,y) = (6,3)[/tex])
[tex]Y'(x,y) = Y(x,y) + U(x,y)[/tex] (Eq. 2)
[tex]Y'(x,y)=(6.5, 5) + (-4.2, 2)[/tex]
[tex]Y'(x,y) = (2.3, 7)[/tex]
[tex]Z'(x,y) = Z(x,y) + U(x,y)[/tex] (Eq. 3)
[tex]Z'(x,y) = (6,3)+(-4.2,2)[/tex]
[tex]Z'(x,y) = (1.8, 5)[/tex]
The coordinates of [tex]Y'(x,y)[/tex] and [tex]Z'(x,y)[/tex] are [tex]Y'(x,y) = (2.3, 7)[/tex] and [tex]Z'(x,y) = (1.8, 5)[/tex], respectively.

A 54-foot tall office building casts a shadow that is 48 feet long. If Mindy is 5’6” tall and standing nearby, find the length of her shadow.
Answer: 200ft
half
Step-by-step explanation for the question i don't know: I don't have the true answer but would it be half...? nvm lol
Answer:
[tex]\huge\boxed{\frac{44}{9} \ \text{feet}}[/tex]
Step-by-step explanation:
If the sun hits two objects at the same time of day, their shadow lengths will be proportionate to their original object with same constant of proportionality.
Therefore, we can set up a proportion fraction to find Mindy's shadow length. Let's assume we have the fraction as [tex]\frac{\text{original}}{\text{shadow}}[/tex].
[tex]\frac{54}{48}=\frac{5.5}{x}[/tex]
We use 5.5 because 5'6" is the same thing as 5.5 feet - 6 inches is half a foot.
We can solve for x by cross multiplying.
[tex]48 \cdot 5.5=264[/tex]
[tex]264 \div 54 = \frac{264}{54}[/tex]
We can simplify this fraction by dividing the numerator/denominator by 6.
[tex]264 \div 6 = 44\\54\div6=9[/tex]
[tex]\frac{44}{9}[/tex]
So Mindy's shadow is [tex]\frac{44}{9}[/tex] feet long.
Hope this helped!
find the next three terms in the arithmetic sequence: -3, -8, -13, -18
Answer:
-23
Step-by-step explanation:
Common difference = 2nd term - 1 st term

= -8 + 3
= -5
To get the next term add (-5) to the previous term
5th term = (-18) + ( (-5) = -23

Answer:
Step-by-step explanation:
For exercises 23-27 use this illustration of a drink dispenser gauge on the front of the dispenser shows how much of the liquid remains in the gauge that dispenser holds 120 cups a. About what fraction of the cup is filled with liquid b. About how many cups of liqiud are in the dispencer c. About what fraction of the dispencer is empty d. About how many more cups of liquid does it take to fill the cup
Answer:
a) 2/3
b) 80 cups
c) 1/3
d) 40 cups
Step-by-step explanation:
Fraction of a full dispenser = 1
a. About what fraction of the cup is filled with liquid
= 1 - 1/3
= 2/3
b. About how many cups of liqiud are in the dispenser
We have 120 cups.of liquid that the dispenser contains
Hence,
= 2/3 × 120
= 2 × 40
= 80 cups
c. About what fraction of the dispenser is empty
= 1 - Fraction of liquid currently in the dispenser
= 1 - 2/3
= 1/3
d. About how many more cups of liquid does it take to fill the cup
= 1/3 × 120
= 40 cups
It will take 40 cups to fill the dispenser

What are the x- intercept and the y-intercept of the graph of 6x + 15y = -30?
Answer:
x int: -5
y int: -2
Step-by-step explanation:
Plug in 0 for x to find y intercept. 6(0) + 15y = -30 then you would get 15y = -30. Divide by 15 on both sides. y = -2
Plug in 0 for y to find x intercept 6x + 15(0) = -30 then you would get 6x = -30. Divide 6 on both sides. x = -5

y= -x + 1 and y= 2/3x - 4 What is the solution to the system of equations?
Answer:
x=3 /
steps: (For x)
Turn the equation into --> -x+1 = 2/3x-4
Next is the multiply the equation by 3 to make isolating x easier so it becomes --> -3x+3=2x-12
Now arrange the terms to where variables are on a side and constants are on a side
it should look like --> -3×-2x=-12-3
Now combine like terms --> -5x=-15
finally just divide by -5 on both sides
x=3
For y:
substitute X for either of the equations
y=2/3 x 3-4
y=-2
The solution is (3,-2)

Step-by-step explanation:
its 38
After reducing the given number 40.00 by 5%, the reduced number is, 38
What is the percentage?The percentage is a mathematical term, which means a number or a ratio which is represented in fractions of 100. We use the '%' symbol to represent the percentage.
Formula for percentage;
Percentage = (present quantity/whole quantity)×100
Given that,
The number, 40.00
After reducing it by 5% = ?
5 = (x/40)×100
x = 2
5% of 40 is 2,
So subtracting it from 40
After decreasing it by 5%
The number = 40-2
= 38
Hence, the number is 38
