A motor racing circuit has length 5 5/6 miles. A straight section of the circuit has 1 1/4 miles. What fraction of the circuit is the straight section? Give the answer in its simplest form
Answer:
3/14
Step-by-step explanation:
1 1/4 can be written as 5/4
5 5/6 can be written as 35/6
so divide (5/4)/(35/6)
= (5/4)*(6/35)
=(1/4)*(6/7)
=6/28
simplified = 3/14

Two red and two blocks are placed into a bag you take one of the blocks out of the bag what is the probability the block is not blue
Question:
Two red and two blue blocks....
Answer:
[tex]P(Not\ Blue) = \frac{1}{2}[/tex]
Step-by-step explanation:
Given
[tex]Red = 2[/tex]
[tex]Blue = 2[/tex]
Required
Probability of not selecting blue
First, we calculate the probability of selecting blue
[tex]P(Blue) = \frac{Blue}{Total}[/tex]
[tex]P(Blue) = \frac{2}{2+2}[/tex]
[tex]P(Blue) = \frac{2}{4}[/tex]
[tex]P(Blue) = \frac{1}{2}[/tex]
In probability:
Opposite probabilities sum up to 1 i.e.
[tex]P(Blue) + P(Not\ Blue) = 1[/tex]
This gives
[tex]\frac{1}{2} + P(Not\ Blue) = 1[/tex]
[tex]P(Not\ Blue) = 1 - \frac{1}{2}[/tex]
[tex]P(Not\ Blue) = \frac{2-1}{2}[/tex]
[tex]P(Not\ Blue) = \frac{1}{2}[/tex]

The first term is a = -4Common difference is d = 5Nth term of this sequence is:
aₙ = a + (n - 1)daₙ = - 4 + 5(n - 1) = -4 + 5n - 5 = 5n - 9Correct option is d.
Answer:
d. (5n-9)Step-by-step explanation:
First term = -4Common difference = 1-(-4)=1+4=5Formula used: L =a+(n-1)dwhere, L is the last term;
a is the first term ;
n is the number of terms;
and d is the common difference.
L = -4+(n-1)5= -4+5n-5 = 5n-9Therefore, the last term is (5n-9).
Arthur sets off at 9am. Arthur's journey north will take 2 hours and 35 minutes, but the train makes a stop for 45 minutes at Crewe. What time will he eventually arrive at his destination?
Answer:
I believe the answer to be 12:20 p.m.
Step-by-step explanation:
2 hours and 35 minutes + the 45 minute stop = 3 hours and 20 minutes.
From 9:00 am, 3 hours is 12:00, plus the 20 minutes left over.
Answer:
12:20 PM
Step-by-step explanation:
Simply add 35 and 45, which would give you 80. Since you know that there can only be 60 minutes in an hour, you just subtract 60 from 80, which will give you 20. all those 60 minutes (or an hour) to the 32 hours you already have. Now you have 3 hours. Now add the 20 minutes we have left over and then you have an answer of 3 hours and 20 minutes. Now add 3 hours and 20 minutes to 9 AM and you get an answer of 12:20 PM.

When you divide the number of permutations of 11 objects taken 3 at a time by 3!, you will get the number of combinations of 11 objects taken 3 at a time.
Answer:
Yes
Step-by-step explanation:
Permutation :
nPr = n! ÷ (n - r)!
nCr = n! ÷ (n-r)!r!
11 objects taken 3 at a time :
11P3 = 11! ÷ (11 - 3)!
11P3 = 11! / 8!
11P3 = (11 * 10 * 9 )
11P3 = 990
Dividing by 3!
3! = 3*2*1 = 6
= 990 / 6
= 165
For combination :
11C3 = 11! ÷ 8!3!
11C3 = (11 * 10 * 9) / (3 * 2 * 1)
11C3 = 990 / 6
11C3
A cell phone that regular costs $780 is on sale for 15% off. What is the total cost of the phone if you have to pay 5.5% sales tax? Round to the nearest cent.
Answer:
$700
Step-by-step explanation:
Step one:
Given data
Regular cost of cell phone= $780
discount = 15%
tax = 5.5%
Step two
Let us compute the discounted amount
= 15/100*780
=0.15*780
=$117
hence the selling price is
=780-117
=$663
Also, the tax-deductible is
=5.5/100*663
=0.055*663
=$36.465
The total cost of the phone will be
=663+36.465
=699.465
=$700 to the nearest cent

On a standardized aptitude test, scores are normally distributed with a mean of 100 and a standard deviation of 10. Find the percent of scores that are: a) Between 90 and 100
Answer:
34.134%
Step-by-step explanation:
Given :
Normal distribution ;
Mean, m = 100 ; Standard deviation, s = 10
Percentage score between 90 and 100
P(90 ≤ x ≤ 100)
Recall : Zscore = (x - m) / s
P[(90 - 100) / 10 ; (100 - 100) / 10]
P[(10/10 ; 0 / 10)]
P(Z ≤ 1) - P(Z≤0) (Using Z probability calculator)
0.84134 - 0.5
= 0.34134
= 0.34134 * 100%
= 34.134%

Joakim is icing 30 cupcakes. He spreads mint icing on 1 5of the cupcakes and chocolate on 1 2of the remaining cupcakes. The rest will get vanilla icing. How many cupcakes have vanilla icing?
Answer: 12
Step-by-step explanation:
From the question, we are informed that Joakim is icing 30 cupcakes and that he spreads mint icing on 1/5 of the cupcakes. This means that he spreads 1/5 × 30 = 6 cupcakes.
After spreading 6 cupcakes, he will have: 30 - 6 = 24 cupcakes left. We are told that he spreads chocolate on 1/2 of the remaining. This means that he spreads chocolate on 1/2 × 24 = 12 cupcakes.
Therefore, he will have 12 left
= 24 - 12
= 12
Therefore, the rest that'll get vanilla icing will be 12 cupcakes

Dianna made several loaves of bread yesterday. Each loaf required cups of flour. All together, she used cups of flour. How many loaves did Diana make? 3 loaves 4 loaves 5 loaves 7 loaves
Answer:
5 loaves
Step-by-step explanation:
Dianna made several loaves of bread yesterday. Each loaf required 2 2/3 cups of flour. All together, she used 13 1/3 cups of flour. How many loaves did Dianna make?
Flour per loaf = 2 2/3 Cups of flour
Total cups of flour used = 13 1/3 cups
How many loaves did Dianna make?
Number of loaves Dianna makes = Total cups of flour used / Flour per loaf
= 13 1/3 ÷ 2 2/3
= 40/3 ÷ 8/3
= 40/3 × 3/8
= (40*3) / (3*8)
= 120 / 24
= 5 loaves
Number of loaves Dianna makes = 5

21.5
Step-by-step explanation:
On an archeological field trip, Lucy and Chuck found a total of 92 arrowheads.
If Lucy found 6 more than Chuck, how many did Chuck find?
Answer:
43
Step-by-step explanation:
Let x=lucy and y=chuck
we know that in total they found 92 arrowheads which means that
x+y=92
we also know that lucy found 6 more than chuck which means taht
x-6=y
Let's solve this through substitution
Looking at the second equation we know exactly what y is equal to in terms of x so we can plug this in (x-6) whenever we see a y in the first equation
so we have
x+(x-6)=92
solve for x and get
2x=98
x=49
Now that we know what x is equal to we can solve for y
49-6=y
y=43
This means that lucy found 49 and chuck found 43
Phillip is buying a car for $32,000. He will take out a loan for 3.2% simple interest per year. How much interest will he pay on his car loan after 3 years?
Answer:
$3,072
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 3.2%/100 = 0.032 per year,
then, solving our equation
I = 32000 × 0.032 × 3 = 3072
I = $ 3,072.00
The simple interest accumulated
on a principal of $ 32,000.00
at a rate of 3.2% per year
for 3 years is $ 3,072.00.

6. 3x2 – 2x = 5
Quadratic formula
Answer:
The solution to the quadratic equation be:
[tex]x=\frac{5}{3},\:x=-1[/tex]
Step-by-step explanation:
Given the expression
3x² – 2x = 5
Solving with the quadratic formula
[tex]3x^2-2x=5[/tex]
subtract 5 from both sides
[tex]3x^2-2x-5=5-5[/tex]
Simplify
[tex]3x^2-2x-5=0[/tex]
For a quadratic equation of the form ax²+bx+c=0
[tex]x_{1,\:2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
For a = 3, b = -2, c = -5
[tex]x_{1,\:2}=\frac{-\left(-2\right)\pm \sqrt{\left(-2\right)^2-4\cdot \:3\left(-5\right)}}{2\cdot \:3}[/tex]
[tex]x_{1,\:2}=\frac{-\left(-2\right)\pm \:8}{2\cdot \:3}[/tex]
Separate the solutions
[tex]x_1=\frac{-\left(-2\right)+8}{2\cdot \:3},\:x_2=\frac{-\left(-2\right)-8}{2\cdot \:3}[/tex]
solving
[tex]x_1=\frac{-\left(-2\right)+8}{2\cdot \:3}[/tex]
[tex]=\frac{2+8}{2\cdot \:3}[/tex]
[tex]=\frac{10}{6}[/tex]
[tex]=\frac{5}{3}[/tex]
also solving
[tex]x_2=\frac{-\left(-2\right)-8}{2\cdot \:3}[/tex]
[tex]=\frac{2-8}{2\cdot \:3}[/tex]
[tex]=\frac{-6}{2\cdot \:3}[/tex]
[tex]=\frac{-6}{6}[/tex]
[tex]=-\frac{6}{6}[/tex]
[tex]=-1[/tex]
Therefore, the solution to the quadratic equation be:
[tex]x=\frac{5}{3},\:x=-1[/tex]
Please I would really appreciate It
Answer:
32
Step-by-step explanation:
So since you can see that two of the sides are equal, that means the 2 angles at the bottom of the triangle are both equal to 25. Since the interior angles in a triangle always add up to 180, so it would be:
25 + 25 + 4x + 2 = 180
Solving,
52 + 4x = 180
subtract 52 from both sides
[tex]4x = 128[/tex]
divide both sides by 4
[tex]x = 32[/tex]°
hope that makes sense!
Answer:
x = 32
Step-by-step explanation:
the tic marks on the two sides of the triangle indicate they are congruent; therefore the two base angles are congruent also - each is 25°.
so, we can set up this equation to solve for 'x': 25 + 25 + 4x + 2 = 180
52 + 4x = 180
4x = 128
x = 32
