Answer:

3.019 hours.

Step-by-step explanation:

In this case they ask us to calculate the time in hours that are in those distances, for this we have the speed and the distance, we know that speed is equal to:

v = d / t

therefore the time would be:

t = d / t

we must pass the distance that is in kilometers to miles, like this:

350 km * 1 mile / 1.61 km = 217.4 mi

Now if replacing:

t = 217.4 / 72 = 3.019

Therefore, the time would be 3.019 hours.

Answer:

Step-by-step explanation:

AP = 8, 24 , 40....

a = 8 , d =16 , n =98 , An = ?

an= a +(n-1)d

an = 8+97*16

an=8+1552

an=1560

hope it helps you..

The 98th term of the arithmetic sequence ( 8, 24, 40, . . . ) is 1560 ( One thousand five hundred and sixty ).

An arithmetic sequence is simply a sequence of numbers in which the difference between the consecutive terms is constant.

The nth term is an arithmetic sequence is expressed as;

aₙ = a₁ + ( n - 1 )d

Where aₙ is the nth term, a₁ is the first term in the sequence and d is the the common difference between terms.

Given the data in the question;

We substitute our given values into the expression above.

aₙ = a₁ + ( n - 1 )d

a₉₈ = 8 + ( 98 - 1 )16

a₉₈ = 8 + ( 97 )16

a₉₈ = 8 + 1552

a₉₈ = 1560

Therefore, the 98th term of the arithmetic sequence ( 8, 24, 40, . . . ) is 1560 ( One thousand five hundred and sixty ).

Answer:

It is 4 cavities

Step-by-step explanation:

The interquartile range (IQR) of the data in the dot plot is 4

From the question, we are to determine the interquartile range (IQR) of the data

From the diagram, we can produce the data set

0, 0, 0, 1, 1, 3, 3, 4, 7, 7

Now, we will determine the interquartile range of this data set.

The interquartile range is the difference in value between the upper quartile and lower quartile.

The upper quartile (Q3), is the value under which 75% of data points are found when arranged in increasing order.

The lower quartile (Q1), is the value under which 25% of data points are found when they are arranged in increasing order.

∴ IQR = Q3 - Q1

From the data set

0, 0, 0, 1, 1, 3, 3, 4, 7, 7

Upper quartile (Q3) = 4

and

Lower quartile (Q1) = 0

∴ Interquartile range (IQR) = 4 - 0

IQR = 4

Hence, the interquartile range (IQR) of the data in the dot plot is 4

Answer: 187.5 tons of cement

Step-by-step explanation:

From the question, Sadie's Road Paving Company used 750 tons of cement to pave 4 miles of roadway. To calculate the number of cement on average that the company use per mile, we divide 750 tons of cement by 4 miles. This will be:

= 750 tons of cement/4

= 187.5 tons of cement

The company used 187.5 tons of cement per mile.

Answer: The company used 187.5 tons per mile.

Step-by-step explanation:

Hi, to answer this question we simply have to divide the amount of cement used (750 tons) by the miles that the company pavemented (4 miles):

Mathematically speaking:

750 t / 4 m = 187.5 tons per mile

The company used 187.5 tons per mile.

Answer:

9,11

Step-by-step explanation:

let the numbers be x, x+2 (since consecutive odd integers have a difference of 2)

therefore;

x(x+2)= 99

x²+2x=99

I usually solve the sum like this,

we need to find the nearest square number ( number smaller than the number on the R.H.S)

here, it is 81, whose square root is 9. therefore the solution is 9

verification:

(9)²+2*9=99

81+18=99

99=99

hence, 9 is the solution. therefore the positive odd consecutive integers are  

x=9

x+2=9+2= 11

verification:

9*11=99

99=99

L.H.S=R.H.S

Answer:

9=7+a....................equation 1

a+8=b+5................equation 2

equation 1

9=7+a

9-7=a

2=a

a=2

put equation 1 into equation 2

2+8=b+5

10= b+5

10-5= b

5=b

b=5

meaning value of b=5

The value of b is 5 for the given equations 9 = 7 + a and a + 8 = b+5.

The substitution method is the algebraic method to solve simultaneous linear equations. In this method, the value of one variable from one equation is substituted in the other equation.

According to the given question we have , two equations

[tex]9 = 7+a...(i)[/tex]

and [tex]a + 8 = b + 5...(ii)[/tex]

From equation (i)

9 = 7 + a

⇒ a = 9 -7

⇒  a = 2

Substitute the value of a in equation (ii)

⇒ 2 + 8 = b + 5

⇒ 10 = b + 5

⇒ b = 10 -5

⇒ b = 5

Hence, the value of b is 5 for the given equations 9 = 7 + a and a + 8 = b+5.

Answer:

Step-by-step explanation:

According to the diagram shown, ∠OPQ = ∠OQP = 18°. If PQT is a tangent to the circle, it can be inferred that line OQ is perpendicular to line QT. Ths shows that ∠OQT = 90°.

Also from the diagram, ∠OQP + ∠PQT = ∠OQT;

∠PQT  = ∠OQT -  ∠OQP

Given ∠OQP = 18° and ∠OQT = 90°

∠PQT = 90°-18°

Step-by-step explanation:

Supplementary is defined as two angles whose sum is 180. These angles must therefore be on a straight line cut by a transversal and must be less than 180 by themselves.

If one angle is 159, then we can simply subtract it from 180 to get the other angle.

A more algebraic way is to set up the equation, 159 + x = 180. Subtract 159 from 180 to find x.

The Measure of supplementary angle is 21⁰.

The pair of angles that always add up to 180 degrees are referred to as supplementary angles. The term "supplements of each other" refers to these two angles. The Latin words "Supplere" and "Plere" are the source of the word "supplementary." "Supplere" means "supply," while "Plere" means "fill." Thus, "something when supplied to complete a thing" is the definition of "supplementary."

Given an angle 159⁰

and according to supplementary angles property,

when sum of two angles is 180⁰ are supplementary

∠A + ∠B = 180⁰ (angles are supplementary)

Let the another angle be x

159 + x = 180

x = 180 - 159

x = 21⁰

Hence the supplementary angle is 21⁰.

Answer: x(-1.8-6y)  =  -1.8*x -6*y*x

Step-by-step explanation:

The distributive property says that if we have:

A*(B + C) where A, B and C can be any numbers, we can expand the equation as:

A*(B + C) = A*B + A*C.

So, in this case, we have the equation:

x*(-1.8 - 6y)

so we can expand this as:

x*(-1.8 - 6y) = x*(-1.8) + x*(-6*y) = -1.8*x -6*y*x

C. picking a 4 of diamonds from a standard deck of cards

Step-by-step explanation:

First, we need to remember what the possible outcomes of a deck of cards, a flipped coin, and a standard number cube are.

A standard deck of cards has a total of 52 cards. There are 4 cards with a 7 on them. There is only one card with a 4 of diamonds. A nickel has 2 sides, and each side is equally likely show after a coin toss. A number cube has 6 faces with a different number from 1 to 6 on each face.

Now we find the probability of each situation. To find the probability of an event, divide the number of ways the desired event can happen by the total number of outcomes.

1. p(7) = 4/52 = 1/13 = 0.0769

2. p(tails) = 1/2 = 0.5

3. p(4 of diamonds) = 1/52 = 0.0192

4. p(number greater than 2) = 4/6 = 2/3 = 0.667
