Answer: $J/3 + $5

Step-by-step explanation:

Here is the complete question:

Angela shared a cab with her friends. When they arrived at their destination, they evenly divided the $j fare among the 3 of them. Angela also paid a $5 tip. How much did Angela pay in total?

Write your answer as an expression.

Answer:

From the question, we are told that Angela shared a cab with her friends and when they arrived at their destination, they shared equally the $j fare among the 3 of them while Angela also paid a $5 tip.

The total number of friends are =3

The amount of fare = $ J

The fare is equally divided among the friends, therefore each friend will pay: $J/3

Angela paid $5 additional as a tip, therefore, her share will be: J/3 + 5

Therefore, Angela will pay $J/3 + $5

Answer:

The sum is a binomial with a degree of 6

Step-by-step explanation:

we have

(3x^{2}y^{2}-2xy^{5})+(-3x^{2}y^{2}+3x^{4}y)

Group terms that contain the same variable

(3x^{2}y^{2}-3x^{2}y^{2})-2xy^{5}+3x^{4}y

0-2xy^{5}+3x^{4}y

-2xy^{5}+3x^{4}y

The sum is a binomial ( two terms) with a degree of 6  

-2xy^{5} has a degree of 6 (x has an exponent of 1, y has 5, and 1+5=6)

Answer:

The answer is 10⁴ × 4⁵.

Step-by-step explanation:

First, you can seperate the fraction :

[tex] \frac{ {10}^{4} \times {4}^{10} }{ {4}^{5} } [/tex]

[tex] = {10}^{4} \times \frac{ {4}^{10} }{ {4}^{5} } [/tex]

Next, you have to apply Indices law :

[tex] {a}^{m} \div {a}^{n} = {a}^{m - n} [/tex]

So for this question :

[tex] {10}^{4} \times \frac{ {4}^{10} }{ {4}^{5} } [/tex]

[tex] = {10}^{4} \times {4}^{10 - 5} [/tex]

[tex] = {10}^{4} \times {4}^{5} [/tex]

Answer:

91+c

Step-by-step explanation:

The equation to find the perimeter of the triagle is every side added together. We know 2 sides which means we add them to get 91. Then we know we don't know the next number but we add it so we just put the c where the next number to be added would go.

Answer:t=8

Step-by-step explanation:

solve for t by simplifying both sides of the equation,then isolating the variable

Answer:

[tex]t = 8[/tex]

Step-by-step explanation:

→You need to get "t," by itself, and to do this, you must multiply both sides by the reciprocal of [tex]\frac{1}{4}[/tex], which is 4. You are multiplying because you can't divide by a fraction.

[tex]\frac{1}{4} t=2[/tex]

[tex]4*\frac{1}{4} t=2*4[/tex]

[tex]t = 8[/tex]

Answer: -2.6%

Step-by-step explanation:

Percent error is the difference between the measured and known value, and then we divide by the known value, and then multiply by 100%.

Estimated.number = 15.4 grams.

Actual number = 15.8 grams

Percentage error = (Estimated number - Actual number)/Actual number × 100

= (15.4 - 15.8)/15.8 × 100

= -0.4/15.8 × 100

= 0.0253 × 100

= 2.53

= -2.6% approximately

Answer: ZR and ZS form a right angle

Step-by-step explanation:

Complementary angles are angles whose sum = 90ᴼ

If R and S are complementary, then their angle measures add to equal 90ᴼ

A right angle = 90ᴼ

ZR and ZS form a right angle.

When the sum of two angles is equal to 90 degrees, they are called complementary angles.

When two straight lines intersect each other at 90˚ or are perpendicular to each other at the intersection, they form the right angle.

According to the given question.

Angles R and S are complementary angles.

Since, R and S are complementary angles. then their angle measured add to equal to 90 degrees or right angle.

Therefore,

The ZR and ZS form a right angle.

Hence, option second is correct.

Answer:

4.06451 hours

note this answer is not rounded as you did not indicate round to what decimal values.

Step-by-step explanation:

Solving using equation

500 ≤ 248 + 62x

500-248 ≤  62x

252 ≤  62x

252/62 ≤  x

4.06451 ≤  x

Another way to solve

500-248= 252

she needs to travel 252 miles

speed = 62mph

note: speed =  distance/time

therefore time= distance/speed

time = 252/62 = 4.06451

Number of hours Sierra needs to travel to meet her goal is 4.065 hours.

Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.

Sierra wants to drive at least 500 miles today.

She has already driven 248 miles.

Remaining distance is driving at a constant speed of 62 miles per hour.

Let the time needed for the remaining distance to complete is x.

Speed = Distance / Time

Distance = Speed × Time

Distance = 62x

Total distance covered = 248 + 62x

This must be at least 500.

248 + 62x ≥ 500

62x ≥ 500 - 248

62x ≥ 252

x ≥ 252 / 62

x ≥ 4.065

Hence Sierra has to drive at least 4.065 hours to meet her goal.

Answer:

Fiona gets £ 174

Step-by-step explanation:

Ths problem has three unknowns: the amounts each person gets. So let's identify each amount with a letter to write them in mathematical equation form:

Amount Sushil gets is : "x"

Amount Fiona gets is : "y"

Amount Pip gets is : "z"

Now we write three equations based on the information we have:

1) the addition of all these amounts should equal the 580 total:

x + y + z = 580

2) Sushil (x) gets twice as much as Fiona (y):

x = 2 y

3) Fiona (y) gets three times as much as Pip (z):

y = 3 z

So we can write the first equation in terms of "z" only, by using the appropriate substitutions in the intermediate stes:

Replace every instance of "y" with "3 z":

Equation 2 can give then "x" in terms of "z" as well:

x = 2 y = 2 (3 z) = 6 z

Then Eq 1 becomes:

6 z + 3 z + z = 580

10 z = 580

and therefore:

z = £ 58

Now Fiona's amount (y) is "3 times z", therefore:

y = 3 * 58 = £ 174

A word that describes the slope of the line is negative. The correct answer is option B.

A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data. It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

For this case the first thing you should know is that we have an equation of the form:

y = mx + b

Where,

m: The slope of the line

b: Cutting point with the vertical axis.

For this case, we observe that the values of y decrease when the values of x increase. Therefore, the function decreases.

This means that it is true that:

m < 0

Therefore, the slope of the line is negative.

If a number is increased by 8, the result is 25 Find the number.

Step-by-step explanation:

Let x be the number.  Increasing x by 8 gives x + 8, which we are told is 25.  Therefore, x + 8 = 25.  Subtract 8 from both sides to find x = 17.  So, the number is 17.
