Answer:
5.x^8.y^3
Step-by-step explanation:
15.x^10.y^5.z^2 ÷ 3.x^2.y^2.z^2
= 15/3. x^(10-2). y^(5-2). z^(2-2)
= 5.x^8.y^3.z^0
= 5.x^8.y^3
[tex]\\ \rm\hookrightarrow \dfrac{15x^{10}y^5z^2}{3x^2y^2z^2}[/tex]
[tex]\\ \rm\hookrightarrow 5x^{10-2}y^{5-2}z^{2-2}[/tex]
[tex]\\ \rm\hookrightarrow 5x^8y^3[/tex]
Option B has type error or none of the above
A $40 shirt now selling for $28 is discounted by what percent?
Answer:
30%
Step-by-step explanation:
Think of this as converting a fraction. 28/40 to x/100. You do this because in the situation, 40 is 100 percent of the price. So 28 is x percent of 100.
You multiply 40 by 2.5 to get to 100, so multiply 28 by the same number to get x. 28 * 2.5 = 70.
So 28 is 70 percent of 40. But the question is asking by what percentage it is discounted. If it's now selling for 70%, it has been discounted 30%. So the answer is 30%

Answer:
1)
Perimeter=24 inches
Area= around 43.46 inches
Step-by-step explanation:
1) Perimeter = 3in * number of sides
Perimeter = 3*8 = 24
Area= 2(1+ square root of 2) length of one side squared
=42.46
2)
Perimeter = 24
Area= 43.46 inches squared- 3inches
3)
Perimeter = 24
Area= 43.46- triangle area
triangle area = height x base /2
Height = 3, we can compare it.
Base = 3
Triangle = 9/2
Area = 43.46- 4.5
Area =38.96
Can't see 4 and 5 for some reason
6)
Perimeter = 30
Area = 61.94

Five apples and four oranges cost $11.80. One apple and six oranges cost $9.90. how much does one orange cost?
Answer:
the cost of orange is 170
Answer:
One orange costs $1.45.
Step-by-step explanation:
Since there are two variables, you have to set up a 2 variable equation.
Let's let a = apples and o = oranges.
So, we can set up this problem as:
5a + 4o = 11.80
1a + 6o = 9.90
You can solve a 2-variable equation using either elimination or substitution. Here, I think it's easier to use substitution. To do that we have to substitute one variable with an equation that uses only the other so that we only have one variable.
We can manipulate our second equation so that it is:
a = 9.90 - 6o
Then, we can plug this in for a in the first equation. So,
5 (9.90 - 6o) + 4o = 11.80
49.5 -30o +4o = 11.80 (Distribute the 5)
49.5 - 26o = 11.80 (Combine like terms)
-26o = -37.7 (Subtract 49.5 from both sides)
o = 1.45 (Divide by -26)
o = 1.45
So, an orange costs $1.45.
solve for the variable,x, in the following equation 6x+1=x-5
Answer:x = 1.2
Step-by-step explanation:
Answer:

[tex]6x + 1 = x - 5 \\ 6x - x = - 5 - 1 \\ 5x = - 6 \\ x = \frac{ - 6}{5} \\ x = - 1.2[/tex]
During the first several rounds of a golfing league, Nate made par or better on 34 out of 85 holes. Based on this relative frequency, how many pars or better could he be expected to make on the remaining 150 holes? Round to the nearest whole number if necessary.
Answer: 60 holes
Step-by-step explanation:
Nate made par or better 34 out of 85 holes. You need to use this to find the rate at which he makes par or better holes:
= 34 / 85 * 100%
= 40%
40% of the time he makes par or better holes.
If there are 150 holes left, he will make par or better of:
= 40% * 150
= 60 holes

Which sequences of transformations will map circle
M onto circle N?
Answer:
1: Reflect M across the x-axis
2: Dilate about the center by 3/2
Step-by-step explanation:
Given
See attachment for M and N
Required
Which maps M to N
The coordinates of the radius of the circles are:
[tex]M = (5,5)[/tex]
[tex]N = (5,-5)[/tex]
And the radius of circles are:
[tex]r_M=2[/tex]
[tex]r_N=3[/tex]
The first transformation from M to M' is:
- Reflect across the x-axis
The rule is:
[tex](x,y) \to (x,-y)[/tex]
[tex]M(5,5) \to M'(5,-5)[/tex]
At this point, M' and N now have the same center but different radius.
The second transformation from M' to N is:
- Dilate about the center by dividing the radius of N by the radius of M
i.e.
[tex]k =\frac{r_N}{r_M}[/tex]
[tex]k =\frac{3}{2}[/tex]
At this point, M has been completely mapped to N.
Determine the slope of the line.

On the same exam, Alyssa's friend Jessie answered three times more questions correct than incorrect. Who got a higher percentage of the test questions correct, Alyssa or Jessie?
Complete question is;
Alyssa took a math test with 20 questions and she answered 16 questions correctly. In order get an A, she needs to answer at least 90 percent of the questions correctly.
A) Did Alyssa get an A on this math test? Explain.
B) How many questions would Alyssa need to answer correctly in order to get an A?
C) On the same exam, Alyssa's friend Jessie answered three times more questions correct than incorrect. Who got a higher percentage of the test questions correct, Alyssa or Jessie
Answer:
A) she didn't get an A because she scored less than 90%.
B) She will need to answer 18 correctly to get an A.
C) Alyssa had a higher percentage.
Step-by-step explanation:
A) Alyssa answered 16 out of 20 questions correctly.
Converting this to percentage gives;
16/20 × 100% = 80%
Now,we are told she needs at least 90% correct answers to get an A.
She scored 80% which is less than 90% mark of A, therefore she didn't get an A.
B) Let the number of minimum questions to answer correctly out of 20 be x.
Thus, since it is 90%.
Then;
x/20 × 100% = 90%
making x the subject;
x = 90 × 20/100
x = 18
She will need to answer 18 correctly to get an A.
C) her friend Jessie answered three times more questions correct than incorrect.
This means for every 4 questions answered, she had 3 correct and 1 incorrect.
Thus,
For 4 questions she had 3 correct answers, then for 20 questions, she will have: 20 × 3/4 = 15 correct questions
Which corresponds to;
15/20 × 100% = 75%
Thus, Alyssa had a higher percentage.
Marlene estimates that 48% of 1,220 is about 600. Which estimates describes why this is a reasonable estimate?
Answer:
By rounding
Step-by-step explanation:
48 % means 48 percent which 48 out of 100.
48% of 1220
= 48/100*1220
= 0.48*1220
=585.6 which is almost equal to 600
1) By rounding
Now if we round 48% we get 50 % as 8 > 5 and 1 is added to 4 making it 5 in tens place leaving 0 in unit's place.
So 50% of 1220
0.50*1220= 610
Again rounding 610 would give 600 as 1 is less than 5 and we drop it out from the tens place leaving zero behind.
2) Complementary
IF we subtract 48% from 100% we get 52%.
So 52% of 1220 would be 634.4
IT again can be rounded in 2 ways Either 52% can be rounded to 50% and 634.4 can be rounded to 600.
Both would give 600

Please help me with my work
Answer:
If the squares of the two shorter sides add up to the square of the hypotenuse, the triangle contains a right angle.
Step-by-step explanation:
Answer:
Down below is the answer.
Step-by-step explanation:
So, lets remember that the pythagreon theorm is only useable in right traingles.
The formula for the pythagreons theorm is A^2+B^2=C^2
So basically, if this is not a right triangle, the two sides(4ft^2 and 3ft^2) will be equivelent to 5ft^2.
Lets solve the pythagroens theorm and plug in our values:
4^2+3^2=5^2
Now lets use the square roots:
16+9=25
COmbine the two numbers:
25=25
This is correct!
So yes, this is a right triangle.
HOpe this helps! :)
Which shape contains exactly two pairs of parallel lines?
Trapezoid
Rectangle
Equilateral triangle
Acute triangle
Answer:
Rectangle is the correct answer hope it helps you have a great day keep smiling be happy stay safe ☺️
A rectangle is a special type of parallelogram. Any parallelogram has two pairs of opposite parallel sides. A rectangle is a parallelogram where all four angles are the same, and all four angles are 90 degrees.
Keep in mind that not all parallelograms are rectangles, but any rectangle is always a parallelogram.
In slight contrast, a trapezoid has exactly one pair of parallel lines, while the other pair of opposite sides are not parallel. Triangles of any kind can be ruled out because they don't have any parallel sides at all.

What is the range for this data set?
Answer:
range = 9
Step-by-step explanation:
The range is the difference between the largest and smallest values
largest value = 12
smallest value = 3
range = 12 - 3 = 9
Answer:12-3=9
Step-by-step explanation:To find the range,you have to subtract the highest number and the lowest number which in this case the highest number is 12 and the lowest number is 3 so the answer is 9.

Step-by-step explanation:
idek but Goodluck and I hope you figure it our bye.
Answer:
x=16√3 units
y=8√3 units
z=24 units
Step-by-step explanation:
z=(24√2)/√2=24 which means the height is also 24 following 45-45-90 triangle rules
y=24/√3=24√3/3=8√3 (remember 30-60-90 triangles rules and to rationalize the denominator)
x=2y=2(8√3)=16√3 (remember 30-60-90 triangle rules)
