Answers

Answer:

answers is down there

Step-by-step explanation:

you can use fraction strips by using them 3/4 and 6/8 because they are equivalent and that's just life :)

3/4 and 6/8 are equivalent numbers/fractions

The fractions are given as:

[tex]\frac 34[/tex] and [tex]\frac 68[/tex]

To model 3/4 using number lines, we do the following steps

Draw a straight lineDivide into 4 equal segmentsPut a mark at the end of the 3rd point

To model 6/8 using number lines, we do the following steps

Draw a straight lineDivide into 6 equal segmentsPut a mark at the end of the 6th point

When both points are compared, then we find out that:

[tex]\frac 34 \equiv \frac 68[/tex]

Hence, 3/4 and 6/8 are equivalent

Age If you add Natalie's age and Fred's age, the result is 43. If you add Fred's age to 4 times
Natalie's age, the result is 79. Write and solve a system of equations to find how old Fred and
Natalie are.
Fred is
years old. Natalie is
years old.

Answers

Let’s take fred age as x and Natalie’s age as y.
So,
A/Q
X + Y = 43. Let it be eqution 1
and
X + 4Y = 79. Let it be equation 2

Combining equation 1 and 2, we get

( X + Y) + 3Y = 79
43 + 3Y = 79
3Y = 36
Y = 12

Now, evaluating the value of Y in equation 1 we get,

X + 12 = 43
X = 31

Therefore, Fred is 31years old and Natalie is 12 years old.

Step-by-step explanation:

A cup of coffee contains 140 mg of caffeine. If caffeine leaves the body at 10% per hour, how long will it
take for half of the caffeine to be eliminated from one's body?

Answers

Answer: 5 hours

Step-by-step explanation:

If 10% of 140 is 14. And if 14 mg of caffeine is leaving per hour then it would take 10 hours to completely leave from ones body, but for half of it to leave it would take 5.

It takes 5 hours to eliminate half of the caffeine from one's body.

Given that, a cup of coffee contains 140 mg of caffeine.

What is the percentage?

In mathematics, a percentage is a number or ratio expressed as a fraction of 100.

Now, 10% of 140

=0.1×140=14 mg

If 10% of 140 is 14 and if 14 mg of caffeine is leaving per hour then it would take 10 hours to completely leave from one's body, but for half of it to leave it would take 5 hours.

Therefore, it takes 5 hours to eliminate half of the caffeine from one's body.

Answer:

What is the measure of angle D?

52o

Angle D = 360-128-126-54 = 52o

Step-by-step explanation: got it right on edge

Since the sum of the angles in a quadrilateral is 360 degrees then the angle D is 50 degrees.

What is a quadrilateral?

A quadrilateral is a four sided figure. Examples of quadrilaterals include; square, parallelogram, rectangle, kite etc.

The sum of angles in a quadrilateral is 360 degree hence;

A + B + C + D = 360 (sum of angles in a quadrilateral)

128 + 126 + 54 + D = 360

D = 360 - ( 128 + 126 + 54)

D = 50 degrees

B- what will Sarah earn when the tips are $350? Explain your strategy

C- what were the nightly tips when Sarah earned $81? Explain your strategy

Thank you :]

Answers

Answer:

A: E = 0.05t +56

B: $73.50

C: $60.05

Step-by-step explanation:

A) I'll just explain the equation in one go

Equation: E = 0.05t + 56

0.05 - This is meant to represent the 5% of tips

5% = 5/100

5/100 = 0.05

56 - This is a set value that has been established as a constant, thus it simply needs to be added to the 5%

B+C) Since we already have the equation set up, we just need to plug in the variable, t.

B) E = 0.05(350) + 56

= 17.5 + 56

= 73.50

C) E = 0.05(81) + 56

= 4.05 + 56

= 60.05
