Walter had 2/4 yard of string. He used 3/6 of it on a school project. How much string did he use?

Answers

2/4 reduces to 1/2

 3/6 reduces to 1/2

 so he used 1/2 of 1/2 yard

1/2 * 1/2 = 1/4

he used 1/4 yard

We have 2/4 yard of string and we are using 3/6 of it. Sometimes in mathematics, the word 'of' means 'multiply'.

[tex]\frac{2}{4} * \frac{3}{6} = \frac{6}{24}[/tex]

Simplify.

[tex]\frac{6}{24} = \frac{1}{4}[/tex]

So, 1/4 is the answer.

Bodhi has a collection of 175 dimes and nickels. The collection is worth $13.30. Which equation can be used to find n, the number of nickels in the collection?
ANSWER- 0.1(175-n)+0.05n=13.30

Answers

n+d=175, so d=175-n

0.05n+0.1d=13.30  now using d found above in this equation yields:

0.05n+0.1(175-n)=13.30

...

1.5(4-g)+1g=5.5

6-1.5g+g=5.5

6-0.5g=5.5

-0.5g=-0.5

g=1

5.5/4=1.375

So your grid should be:

3oz    1.50     4.50

1oz    1.00     1.00

4oz    1.375   5.50




Answer:

The equation we can use is 0.1(175-n)+0.05 n=13.30

Step-by-step explanation:

Number of Dimes= d

Number of Nickels= n

n+d=175, so d=175-n

The value of the dime is $0.10 and the value of each nickel is $0.05 and the whole  collection is worth $13.30, so

0.1 d+0.05 n=13.30

Replacing

0.1(175-n)+0.05 n=13.30 this is the equation we have to use to get the number of nickels.

which statement is always true about an isosceles triangle A.it has 1 right angle B.it has 2 congruent angles C.it has no sides that are congruent D.the sum of all 3 angles in 360 degrees

Answers

b is the correct answer for this question

It has 2 congruent angles, is always true about an isosceles triangle

What is Isosceles Triangle?

A triangle with two equal sides is said to be isosceles. Also equal are the two angles that face the two equal sides. In other terms, an isosceles triangle is a triangle with two sides that are the same length.

Angles of Isosceles Triangle:

Contrary to the equal sides, two of the isosceles triangle's three angles have equal measures. One of the angles is therefore not equal. Assume that if we are given the measure of an unequal angle, we can quickly determine the other two angles using the angle sum property.

Properties of Isosceles Triangle:

Since this triangle's two sides are equal, the base of the triangle is the side that is not equal.

The triangle's two equal sides' opposing angles are always equal.

The vertex (topmost point) of an isosceles triangle is where the altitude of the triangle is calculated.

The third angle of a right isosceles triangle is 90 degrees.

Hence, the answer (b) it has 2 congruent angles

Answers

18 inches. The longest line would be the diameter. Since the radius is half of the diameter, 9x2=18

Answer:

18 inches.

Step-by-step explanation:

We can connect two points of a circle in many ways, as you can see in the picture below.

The longest straight line that you can draw to connect two points is the diameter, that is, the straight line that passes through the center of the circle.

If the circle has 9 inches of radius the diameter will be 9+9 = 18 inches.

if PA=14 and PD=10 what is the length of PC

Answers

To find the length of PC when PA=14 and PD=10, apply the cosine rule formula in trigonometry.

The length of PC can be calculated using trigonometry and the given information.

Since PA=14 and PD=10, we can use the cosine rule to find the length of PC.Applying the cosine rule formula, PC = √(PA2 + PD2 - 2*PA*PD*cos(θ)).Calculate the length of PC by substituting the values: PC = √(142 + 102 - 2*14*10*cos(θ)).

Answer:

y = -3x + 36

Step-by-step explanation:

first let's start with a formula.

y = mx + b

m equals the slope and b equals the y intercept.

slope can also be indetified as a rate of change.

so, looking at the graph we can see that the y intercept is (0, 36) or 36 and the rate of change is 3 subtracted.

John read the first 114 pages of a novel, which was 3 pages less than 1/3 of the novel. Write an equation to determine the total number of pages (p) in the novel. And find the total number of pages in the novel

Answers

114 + 3=117
117 pages is 1/3 of the book
117×3= 251
So there are 251 pages in the novel.

Answer:

351


Step-by-step explanation:

If we add 3 pages to 114, we get a number that is [tex]\frac{1}{3}[/tex] the total number of pages in the novel (p). Thus, we can write:

[tex]114+3=\frac{1}{3}p[/tex]


Solving for p gives us the total number of pages in the novel. So:

[tex]114+3=\frac{1}{3}p\\117=\frac{1}{3}p\\p=\frac{117}{\frac{1}{3}}\\p=117*3=351[/tex]

Thus, total number of pages in the novel is 351.

What is the slope of a line that is perpendicular to the line whose equation is 7x−3y=107x−3y=10?

Answers

This is the concept of algebra, to get the slope of the line we need to rewrite the equation in slope intercept form y=mx+c, where m=slope, c=y-intercept.
Therefore re-writing our expression in slope-intercept form we get:
7x-3y=10
-3y=-7x+10
y=7/3x-10/3
The slope=7/3
hence we conclude that the slope of the line perpendicular to this is -3/7


A television costs $270.25 including 15% tax. How much of cost is the tax

Answers

Final answer:

The tax on the television is $35.25.

Explanation:

To find the amount of tax, we first need to determine the original cost of the television. Since the total cost, including tax, is $270.25, we can set up the equation:

$270.25 = x + 0.15x

Where x is the original cost of the television. Combining like terms, we get:

$270.25 = 1.15x

To solve for x, divide both sides of the equation by 1.15:

x = $270.25 ÷ 1.15

Using a calculator, we find that x is approximately $235.00. Therefore, the tax on the television is:

$270.25 - $235.00 = $35.25

The table shows the estimated number of deer living in a forest over a five-year period. Which type of function best models the data? Write an equation to model the data. Year Estimated Population 0 100 1 79 2 62 3 49 4 39

Answers

We are given the following data:

 

Year       Estimated Population

0                               100       

1                               79       

2                               62       

3                               49    

4                               39       

 

Just by looking at the data we can see that the relationship of year and estimated population is not linear. The decrease in the population does not follow a linear path, that is:

79 – 100 is not equal to 62 – 79

-21 is not equal to -17

 

Therefore, the relationship must be exponential. Let us find the common ratio by dividing the population in year 1 and year 0:

common ratio, r = 79 / 100 = 0.79

This means that the population decreases by 21% every year.

So the model for this data can be written as:

yn = y0 * r^n

Where,

yn = is the population after n years

y0 = initial population

r = growth rate = decreasing

n = number of years

A jacket costs $35 and has an 8 percent tax rate. Which expression will find the cost of the tax on the jacket

Answers

Percent means per one hundred...

$35(8/100)

$280/100

$2.80
Like with pretty much any other percentage problem, convert the percent into a decimal.

To do this, move the percent sign two places to the left and turn the percent sign into a decimal point.

8% = 0.08

There is a 8% tax on the jacket.

So, 0.08 * 35 is the expression you're looking for.

Antoine and Tess have a disagreement over how to compute a 15% gratuity on $46.00. Tess says, “It is easy to find 10% of 46 by moving the decimal point one place to the left to get $4.60. Do that twice. Then add the two amounts to get $4.60 + $4.60 = $9.20 for the 15% gratuity.”

Answers

Tess is correct about figuring 10% but he added 2 of them together which is like adding 10% +10% which is 20% not 15%.

 he should have taken 1/2 of the 4.60 for 5% since 5 is half of 10

 half of 4.60 = 2.30

then add that to the 4.60

4.60 +2.30 = 6.90 is 15%

Answer:Tess 20%

The following data points represent the number of chicken nuggets on each family member's plate. 1, 3, 0, 6? If the mean of the data set is 3 chicken nuggets, find the missing number of chicken nuggets.

Answers

The question assumes there are 5 people at the table. So the number of nuggets are: 1,3,0,6,and x. So your equation is:

[tex] \frac{1+3+0+6+x}{5}=3 [/tex] 

So let's solve what we can of the numerator first: 
1+3+0+6+x=10+x

So now we have:
[tex] \frac{10+x}{5} =3[/tex]

We can multiply both sides by 5 to clear the denominator:
[tex]5( \frac{10+x}{5} )=3(5) \\ 10+x=15[/tex]

Now we isolate the x by subtracting 10 from both sides.
10+x-10=15-10
x=5

So the missing number of nuggets is 5.

Hope that helps. 

The missing number of chicken nuggets will be 5.

What is Mean?

The mean is the straightforward meaning of the normal of a lot of numbers. In measurements, one of the markers of focal propensity is the mean. The normal is alluded to as the number-crunching mean. It's the proportion of the number of genuine perceptions to the absolute number of perceptions.

The following data points represent the number of chicken nuggets on each family member's plate.

1, 3, 0, 6, x

If the mean of the data set is 3 chicken nuggets. Then the missing number of chicken nuggets is calculated as,

3 = (1 + 3 + 0 + 6 + x) / 5

15 = 10 + x

x = 5

The missing number of chicken nuggets will be 5.

a + c = 40
20a + 11c = 728

Multiply equation # 1 by -11, then add the two equations together to clear the 'c' variable and solve for 'a'.

-11(a + c = 40)


20a + 11c = 728
-11a - 11c = -440
------------------------
9a  = 288
Divide both sides by 9
a = 32

a + c = 40
32 + c = 40
subtract 32 from both sides
c = 8

How can the order of operations be used to simplify expressions?

Answers

Order of Operations, also known as PEMDAS (Parentheses, Exponents, Multiplication & Division, Addition & Subtraction), can help to simplify an equation by guiding you through the steps to solve it.

This is because it tells you to solve the parentheses. If there is none, but you've already done this, you solve for exponents, etc. 

The progressive soling of the equation not only makes it physically shorter, but also brings you closer to the answer.

Answer:

The slope of a line that is perpendicular to the line whose equation is  [tex]8y-5x=11[/tex] is [tex]m=-\frac{8}{5}[/tex]                      

Step-by-step explanation:

Given : Equation [tex]8y-5x=11[/tex]

To find : What is the slope of a line that is perpendicular to the line whose equation is given?

Solution :

First we find the slope of the given line,

The general slope form of line is [tex]y=mx+b[/tex] where m is the slope of the line and b is the y-intercept.

Re-write the given equation into general form,

[tex]8y-5x=11[/tex]

Take 5x to another side,

[tex]8y=5x+11[/tex]

Divide both side by 8,

[tex]y=\frac{5}{8}x+\frac{11}{8}[/tex]

On comparing with general form,

The slope of the line is [tex]m=\frac{5}{8}[/tex]

We know,

When two line are perpendicular one slope is negative reciprocal of another.

If the slope of line is [tex]m=\frac{5}{8}[/tex]

Then the slope of perpendicular line on this line is  [tex]m=-\frac{8}{5}[/tex]

Therefore, The slope of a line that is perpendicular to the line whose equation is  [tex]8y-5x=11[/tex] is [tex]m=-\frac{8}{5}[/tex]
