Answers

Answer:

4 hours and 7 hours

Step-by-step explanation:

Marcus = x hours

Donnell = x + 3 hours

Total = 11 hours

x + x + 3 = 112x + 3 = 112x = 8x = 4

So Marcus practiced 4 hours and Donnell practiced  7 hours

Nicole used 3/8 of her ribbon to wrap a present. If she used 6 feet of ribbon for the present, how much ribbon did Nicole have at first? Rewrite the problem as a multiplication question.

Answers

Answer: 16

Step-by-step explanation:

From the question, we are informed that Nicole used 3/8 of her ribbon to wrap a present and that she used 6 feet of ribbon for the present,

To know how much ribbon did Nicole have at first goes thus:

Let the ribbon Nicole has at first be y

Since she used 3/8, this will be:

3/8 × y = 6

3y/8 = 6

Cross multiply

3y = 6 × 8

3y = 48

y = 48/3

y = 16

She had 16 ribbons at first

A car travels 200 meters, then turns right and travels 80 meters and finally makes a U-turn and travels another 120 m. If this is all done in 200
seconds, what is the average speed ?


help pleaseeeee

Answers

Answer:

2 m/s

Step-by-step explanation:

Since speed is total distance over time, we first need to find the total distance the car traveled.

Total distance = 200 + 80 + 120 = 400 m

total time = 200 sec

speed = distance/time = 400/200 = 2 m/s

Answers

Answer:

Step-by-step explanation:

Given the following lengths AB = 64, AM = 4x + 4 and BM= 6x-10, If M lies on the line AB  then AM+MB = AB (addition property)

Substituting the given parameters into the addition property above;

AM+MB = AB

4x + 4 + 6x - 10 = 64

combine like terms

4x+6x = 64+10-4

10x = 74-4

10x = 70

Divide both sides by 10

x = 70/10

x = 7

Note that for M to be the midpoint of AB then AM must be equal to BM i.e AM = BM

To get AM ;

Since AM = 4x+4

substitute x = 7 into the function

AM = 4(7)+4

AM = 28+4

AM = 32

Similarly, BM = 6x-10

BM = 6(7)-10

BM = 42-10

BM = 32

Since AM = BM = 32,. then M is the midpoint of AB

What is the equation for a straight line?

A straight line can be written in the form of equation as, y = mx + c.

Two straight lines intersect each other only at one point.

When two straight lines are parallel to each other the angle between them is zero.

The equation of the straight line from the given graph can be formed as below,

Take any two coordinates from the graph as (1, 10) and (2, 25) respectively.

Suppose the cost be y and the number of pajamas be x.

Now, the equation for the slope can be written as,

(y - 10)/(x - 1) = (25 - 10)/(2 - 1)

⇒ (y - 10)/(x - 1) = 15

⇒ y = 15x - 5.

Then, the cost of 6th pajama can be calculated by substituting x = 6 in the above equation as,

y = 15 × 6 - 5

  = 85

Hence, the cost of sixth pair of pajama is $85.

D. Not enough information is given for the value of a to be determined.

Answers

Answer:

A. To determine the value of a, set up and solve a system of equations in two variables. The value of a is 2

Step-by-step explanation:

Given the coordinates F(b+1, a+2, M(3,5) and G(2a, 3b+3), if M is the midpoint of F and G then, to get the value of a and b we will use the formula for calculating the midpoint a shown;

M(X, Y) = (x₁+x₂/2, y₁+y₂/2)

X = x₁+x₂/2 and  Y = y₁+y₂/2

From the given coordinates x₁ = b+1, y₁ = a+2, x₂ = 2a, y₂ = 3b+3, X = 3 and Y = 5

Substituting the given parameters into the formula, we can form up a simultaneous equation and get the value of a.

To determine the value of a, set up and solve a system of equations in two variables

For the X coordinates;

X = x₁+x₂/2

3 = b+1+2a/2

6 = 2a+b+1

2a+b = 5 ............... 1  * 1

For the Y coordinates;

5 = a+2+3b+3/2

cross multiply

10 =  a+2+3b+3

collect like terms

a+3b = 10-2-3

a+3b = 5 ........ 2  * 2

Solving the resulting  simultaneous equation to get the value of a

multiply equation 1 by 1 and 2 by 2 to have the resulting equations;

2a+b = 5 ...........3  

2a +6b = 10.......... 4

subtract 3 from 4

(2a-2a)+(b - 6b) = 5-10

0-5b = -5

b = -5/-5

b = 1

substitute b =1 into equation 1 to get a;

2a + b = 5

2a + 1 = 5

2a = 5-1

2a = 4

a = 2

From the calculation above it is seen that the value of variable a can be determined and it is equivalent to 2

Check all that apply.

O C. 12:36
O D. 3:5
O E. 15:25

Answers

Answer:

D. 3:5 and E. 15:25

Step-by-step explanation:

If it is 60%, it means that the ratio is 6:10 (60/100).

Because both 6 and 10 are divisible by 2, we can then simplify the ratio to 3:5.

Therefore it is D. 3:5

We can then multiply both sides by 5 which will give us 15:25, so E is also correct.

The others of not correct because they are not equivalent to the ratio 3:5.

The medicinal thermometer commonly used in homes can be read to pm0.1°F, whereas those in the doctor's office may be accurate to pm0.1°C. In degrees Celsius, express the percent error expected from each of these thermometers in measuring a person's body temperature of 38.7°C.

Answers

Correct question is;

The medical thermometer commonly used in homes can be read +/-0.1 °F, whereas those in the doctor's office may be accurate to +/- 0.1 C in degrees Celsius, express the percent error expected from each of these thermometers in measuring a person's body temperature of 38.9 °C

Answer:

A) percent error in homes = 0.144 %

B) percent error in doctors office = 0.257 %

Step-by-step explanation:

A) Temperature is 38.9° C

Converting to Fahrenheit using the formula; (°C × 9/5) + 32

So;

(38.9°C × 9/5) + 32 = 102.02 °F

Since thermometer in homes can be read to +/-0.1 °F, then

Expected values = 102.02 +/- 0.1 = 102.12 °F or 101.92 °F

Since we want to find the error from °C, let's convert to °C.

We will use 101.92 °F.

Thus; 102.12 °F = (101.92 - 32) × 5/9 = 38.844 °C

Thus percent error = (38.9 - 38.844)/38.9) × 100% = 0.144 %

B) Temperature is 38.9 °C

Since thermometer in Doctors office can be +/- 0.1 °C, then;

Expected values = 38.9 +/- 0.1 = 38.8 °C or 39 °C.

We will use 38.8°C

Thus;

percent error = (38.9 - 38.8)/38.9) × 100% = 0.257 %
