Laurel ran 3 miles in 24 minutes.At that rate,how long will it take her to run 7 miles?
Answer:
it took her 60 mins which is a hour
Step-by-step explanation:
you would simply add 24 plus 24 and get 48 then u would take 24 and divide that by 2 and get 12 and then u would add 48 and 12 and get the final answer of 60
Answer:
it would take laurel 56 minutes to run 7 miles.
Step-by-step explanation:
She has to run 7 miles, so if she can run 3 in 24 minutes, you can double that time to 48 minutes to run 6 miles, on top of adding another 8 minutes due to 1/3 of 24 (the third being equal to 1 mile since 24 is 3 miles) being 8, leaving you with 56 minutes for her 7 mile run.

Why is 9.68 an irrational number
An irrational number is a number that cannot be represented by a fraction, or must be represented by other irrational numbers. In this case, however, 9.68 can be represented by 9 17/25 , so 9.68 is NOT an irrational number.
Ricky says (x5)(x3) = x15 Rocky says (x5)(x) = x ? Who is correct? Why?
Answer:
1.rocky
Step-by-step explanation
1.we have the add the powers of x,not multiply.
By understanding the concepts of division and multiplication of exponents, we can say that Rocky and Kay are correct.
What is division and multiplication of exponents?If we are multiplying similar bases, we simply add the exponents. If we are dividing, we simply subtract the exponents.

the two angles are supplementary if a=19x+3 and b= 21x +17 solve for x and find the measure of each angle
Answer:
x = 4
a = 79
b = 101
Step-by-step explanation:
Supplementary means equal to 180° after all angles are added together.
a=19x+3
b= 21x +17
(19x+3) + (21x +17) = 180
19x + 3 + 21x + 17 = 180
40x + 20 = 180
40x = 160
x = 4
a = 19(4)+3 = 79
b = 21(4) +17 = 101

A. 112
B. 120
C. 105
D. 126
Answer:it’s 126
Step-by-step explanation:
The length of AC will be 126. Option D is correct. Similarity of the triangle is applied to find the value of AC.
What is SAS similarity theorem?ΔABC ~ ΔDEF only if ratio of two sides of ΔABC and corresponding two sides of ΔDEF is equal, and the angle included in both sides are congruent.
Suppose the two sides of ΔABC are AB and BC, and that of DEF be DE and EF, then for SAS similarity, we need
From the similarity of the triangle;
[tex]\rm \frac{AB}{ED} =\frac{AC}{EC} \\\\ \rm \frac{81}{9} =\frac{140-x}{x} \\\\ 9x=140-x\\\\ 10x=140 \\\\ x=14[/tex]
The measure of AC is;
AC=140-x
AC=140-14
AC=126
The length of AC will be 126.
Hence,option D is correct.

What is the minimum value of F(x)= 10x^{2} -6x-3
3/10 or -39/10
Answer: 3/10
Step-by-step explanation:
Take the derivative of [tex]10x^2-6x-3[/tex] to get [tex]20x-6[/tex]. Set that equal to 0 to find the critical points of the function. The critical points is when the slope is either 0 or undefined.
Now do:
[tex]20x-6=0\\20x=6\\x=\frac{6}{20} = \frac{3}{10}[/tex]
There are quite a few more steps to actually find the minimum, but for this example you can automatically assume its a minimum because it is the only critical point of the function. Ill show you these extra steps tho.
Plug in two numbers into the derivative. One that is less than 3/10 and one that is greater than 3/10. The numbers 0 and 1 are fine. When x = 0, the function is -6. When x = 1, the function is +14. A switch from negative to positive indicates a minimum value

Which function has a greater degree?
Answer:
I think it's either B or C because A and D don't make sense in my opinion.
Step-by-step explanation:
The degree of the p (x) is greater because r (x) is quadratic.
What is Quadratic equation?An algebraic equation with the second degree of the variable is called an Quadratic equation.
Given that;
The function p (x) is,
⇒ p (x) = 4x³ - 2x² + 15
And, The function of r (x) is find by table.
Here, By the given table;
The degree of r (x) is 2, because it is quadratic.
And, The degree of p (x) is 3.
Thus, We can conclude that;
The degree of the p (x) is greater because r (x) is quadratic.

What is a line segment?A line segment is simply defined as the portion of a line connecting two points that are known to be the endpoints.
From the information given, we have that;
Line RS has three segments which are line RS, Line ST and line RT, also S is the midpoint between points R and T
Given that;
Line RS = 2xLine ST = 5x + 4Line RT = 32Then,
RS + ST = RT
Substitute the values
2x + 5x + 4 = 32
collect like terms
7x + 4 = 32
7x = 32 - 4
7x = 28
Make 'x' the subject

Isaac bought 18 boxes of cereal. This is 30% of the total boxes at the store. How many total boxes of cereal were at the store?
Answer:
60
Step-by-step explanation:
30% of total boxes at the store is equal to 18
so
[tex](30 \div 100 ) \times x = 18 \\ x = 18 \times( 100 \div 30) = \\ 18 \times (10 \div 3) = \\ 6 \times 10 = 60[/tex]
The 18 boxes of cereal Isaac purchased. This represents 30% of all the boxes in the store then total boxes of cereal at the store exists 60.
What is meant by percentage?Rather than being expressed as a fraction, a percentage is a piece of a whole expressed as a number between 0 and 100. Nothing is zero percent; everything is 100 percent; half of something is 50 percent; and nothing is zero percent. To exstimate a percentage, you divide the portion of the whole by the whole itself and multiply by 100.
%, which is a relative figure used to denote hundredths of any quantity. Since one percent (symbolized as 1%) is equal to one hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified.
The total no of boxes = y × 100/x
Given x = 30%
y = 18 boxes
Total boxes at the store = 18 × 100/30 = 60
Therefore, the total boxes of cereal at the store exists 60.

1. Jenny is organising a barbecue. There are 30 bread rolls in a pack. There are 16 sausages in a pack. She needs exactly the same number of bread rolls as sausages. What is the smallest number of each pack she must buy?
Answer:
2. Tom, Sam and Matt are doing a show by counting drum beats .They decided to donate the collecting money for the poor children for their studies. Tom hits a snare drum every 2 beats. Sam hits a kettle drum every 5 beats. Matt hits a bass drum every 8 beats. Tom, Sam and Matt start by hitting their drums at the same time. How many beats is it before Tom, Sam and Matt next hit their drums at the same time? What value you can see in their act
Answer:
If you answer I promise I will make you the brainiest, like and I will vote 5
Answer:
Step-by-step explanation:
First find the LCM of 30, 16. This will give the common number of sausages and bread rolls
30 = 2 * 3 * 5
16 = 2 * 2 * 2 * 2
LCM = 2* 2 * 2 * 2 * 3 * 5 = 240
240 sausages and 240 bread rolls
Number of Sausage pack = 240 ÷ number of sausages in a pack
= 240 ÷ 16
= 15
Number of bread roll pack = 240 ÷ number of bread rolls in a pack
= 240 ÷ 30
= 8
Jenny should buy 8 pack of bread rolls and 15 pack of sausage
2) LCM of 2 , 5 , 8 = 40
Tom, Sam, Matt will hit their drum same at 40 minutes
Number of beats hit by Tom before reaching 40 minutes = 40/2 =20 hits
Number of beats hit by Sam before reaching 40 minutes = 40/5 = 8 hits
Number of beats hit by Matt before reaching 40 minutes = 40/8 = 5 hits
