Answer:
16/25 or 64%
Step-by-step explanation:
In this problem we see that 64 out of the 100 students did better on the exams. So, to find the answer we must find the percentage form of 64 out of 100.
Step one:
what exactly is 64 out of 100? Well, in the math world when we see 'out of' we know that means 'divided by'. So, 64 out of 100 is 64/100.
Step two:
now we have to turn 64/100 into a percentage. We know that 1/100 is 1% so lets multiply 1 by 64. 64*1 = 64. This means that 64/100 = 64%.
I'm not 100% sure what form you need your answer in but if you need it in percentage for the answer is 64%. If you need your answer in a fraction form the answer would be 64/100 or 16/25 if we simplify the answer.
I hope this helps!!
How do you solve this?
x and y are integers and 0 < x < y.
Write down two sets of values for x and y such that 6 = /3x+2y.
Answer:
x = 1
y=1.5
Step-by-step explanation:
3*1+2*1.5=6
The values of x and y in equation 6=3x+2y is for x is 1 and for y is 1.5.
We have given that,
x and y are integers and 0 < x < y.
6 = /3x+2y.
x=1 then
What is inequality?A statement of an order relationship greater than, greater than or equal to, less than, or less than or equal to between two numbers or algebraic expressions.
6=3+2y
6-3=2y
3/2=y
y=1.5
3*1+2*1.5=6
Therefore we get the values of x and y is for x is 1 and for y is 1.5.

Is 8.888... a rational number?
=================================================
Explanation:
Since the decimal repeats itself infinitely (the 8s go on forever), this is one sign that we have a rational number.
Rational numbers always have some kind of infinitely repeating pattern when we convert them to decimal form.
---------------------
Extra info (optional section)
If you want to determine what this number is equal to, then let's say that
x = 8.8888...
Multiplying both sides by 10 gets us
10x = 88.888....
Now we'll subtract the two equations
The 10x-x becomes 9x while the 88.8888...-8.8888... turns into 80
We're left with 9x = 80 which solves to x = 80/9
Therefore, 80/9 = 8.8888.... showing that we have a rational number
Any rational number is basically a fraction of two whole numbers.

State the leading coefficient of -9x^5+3x^2+3-7x+10x^3
Answer:
-9
Step-by-step explanation:
We need to write the terms from highest power to smallest power
-9x^5+10x^3+3x^2-7x+3
The leading coefficient is the number in front of the highest power
-9
Answer:
-9
Step-by-step explanation:
In a polynomial, the leading coefficient is the coefficient to the variable with the largest exponent.
In this polynomial, the variable with the largest exponent is x^5.
The leading coefficient is the number in front of the variable. In this case, the leading coefficient is -9.
So, the leading coefficient is -9.

Answer:
a. 1 yard:3 feet
b. 3 feet:1 yard
c. Sean ran exactly a mile
Step-by-step explanation:
For a and b there are 3 feet in a yard
For c a mile is exactly 5280 feet
Answer:
A: 3 : 1
B: 1 : 3
C: less
Step-by-step explanation:
A: There are 3 feet in a yard, so feet: yard would be 3:1
For example, 21 feet equals 7 yards, 21:7 is equal to 3:1B: For every yard, there are 3 feet, so th ratio would be 1:3
For example, 4 yards equals 12 feet, 4:12 is equal to 1:3C: Sean ran 1,600 yards. To convert this into feet, multiply by 3. He ran 4,800 feet. Since 4,800 < 5,280, he ran less than a mile

Triangles ABC and LBM are similar. We know this because AL and LB have the same length, so that AB is twice as long as either AL or LB. The same goes for MC and BM, and BC. The angle B is the same for both tirangles ABC and LBM, so the side-angle-side postulate tells us the triangles are similar, and in particular that triangle ABC is twice as large as LBM.
All this to say that LM must be half as long as AC, so LM has length (B) 14 cm.

so, how many miles are then 2 inches ? hmmm ?
could it be that it is just 2×1 inch = 2×50 miles ?
yes ! it is that simple !
2×50 = 100 miles.
and so, how many miles are 3 inches ?
uuuuuhhhh !
what do you think ?
3×1 inch = 3×50 miles
yeah !
3×50 = 150 miles !
yes, so simple, so easy.

Anyone who can help me with this?
Answer:
C
Step-by-step explanation:
We know that the first integer will be "l" so the second will be l + 1, third will be l + 2, fourth will be l + 3, and the fifth will be l + 4. The question says "the greatest is g" so that means that the fifth integer is the greatest meaning that is the value of g. Now that we know the value of g, we can substitute it into the equation they gave us and simplify.
l+(l+4)/2
2l+4/2
l + 2
Best of Luck!
Answer:
C
Step-by-step explanation:
say your 5 consecutive numbers are 6-10
if 6 is l and 10 is g then
6+10 over 2 equals 8
this proves that l+2 is correct since 6+2=8

B. orders
C. five-number summaries
D. sets
Answer:
C. five-number summaries
Step-by-step explanation:
The point of a boxplot is to represent the distribution of data in a set. It does this by giving a five-number summary. This allows people to easily understand data sets, no matter their size. To compare two boxplots you should compare the values of the five-number summary because this is the complete set of information given in a boxplot.
If a fourth plant produces 150 widgets in 60 days, which statement is true?
A. It makes more than Plant A.
B. It makes less than Plant B.
C. It makes less than Plant A.
====================================================
Explanation:
At the 60 day mark, the following number of widgets are produced
Plant A = 300 widgetsPlant B = 100 widgetsPlant C = 200 widgetsThe fourth plant makes 150 widgets, which is between B and C
We see that the fourth plant does not make more than Plant A, so we can rule out choice A.
The fourth plant does not make less than Plant B, which allows us to rule out choice B.
The only thing left is choice C. Sure enough, this statement is true since 150 widgets made at the fourth plant is less than 300 made in Plant A. This is why choice C is the answer.

1/2 x 70 = 35
10 ÷ 5 = 2
5 x 2 =10

1. Solve x and y for the diagram.
Answer:
B
Step-by-step explanation:
The triangle RUS is similar to RST. 9/sqrt(90)=y/(3+x) and y^2=x^2+81. Solving all this will give x=27 and y=9*sqrt(10)
Value of x is 27 and value of y is [tex]9\sqrt{10}[/tex].
What is angle addition postulate?The angle addition postulate in geometry states that if we place two or more angles side by side such that they share a common vertex and a common arm between each pair of angles, then the sum of those angles will be equal to the total sum of the resulting angle.
X-value:
<RST = [tex]90^{0}[/tex]
[tex]tan( < RSU)= \frac{\overline R \overline U}{\overline S \overline U}[/tex]
[tex]tan( < RSU) = \frac{3}{9}[/tex]
[tex]< RSU = 18.435^{0}[/tex]
Angle addition postulate:
<RST = <RSU + <TSU
[tex]90^{0} =18.435^{0} + < TSU[/tex]
[tex]< TSU =71.565^{0}[/tex]
[tex]tan( < TSU) = \frac{\overline T \overline U }{\overline S \overline U}[/tex]
[tex]tan(71.565^{0})=\frac{x}{9}[/tex]
[tex]x=27[/tex]
Y-value:
<RST = [tex]90^{0}[/tex]
[tex]tan( < RSU)= \frac{\overline R \overline U}{\overline S \overline U}[/tex]
[tex]tan( < RSU) = \frac{3}{9}[/tex]
[tex]< RSU = 18.435^{0}[/tex]
Angle addition postulate:
<RST = <RSU + <TSU
[tex]90^{0} =18.435^{0} + < TSU[/tex]
[tex]< TSU =71.565^{0}[/tex]
[tex]cos( < TSU) = \frac{\overline S \overline U }{\overline S \overline T}[/tex]
[tex]cos(71.565^{0})=\frac{9}{y}[/tex]
[tex]y=9\sqrt{10}[/tex]
Value of x is 27 and value of y is [tex]9\sqrt{10}[/tex].
