"A student measures the length of a rectangularposter to the nearest centimeter and finds thatthe length is 75 cm. Another student measuresthe poster's width to the nearest tenth of acentimeter and finds that the width is 50.3 cm.How should the students report the area of theposter using the correct number of significantdigits?"

Answers

Answer 1

Answer:

See below

Step-by-step explanation:

The result of the calculation of area ( L x W ) should have no more significant digits than the lowest factor ....in this case 75 has only TWO significant digits...... the naswer should have the same ...two

75 * 50.3 = ~3800 cm^2

Using proportions, the amount of acres that each children will be is given by:

9 and 4/5 acres.

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

For this problem 49 acres will be split evenly across 5 children, hence the amount that each will get is:

A = 49/5.

The quotient of 49 and 5 is of 9 with a remainder of 4, hence as a mixed number, the amount is:

9 and 4/5 acres.

find the value of -24/35÷-8/15​

Answers

Answer:

9/7

Step-by-step explanation:

-24/35 ÷ -8/15

=-24/35 × -15/8

=9/7

Answer:

9/7

Step-by-step explanation:

when dividing with a fraction, the -8/15 reciprocates to 15/-8. Then, -8 cancels out -24 remaining with 3 since they are both negative while 15 and 35 have a common of 5 giving them a remainder of 3 and 7 respectively. you then multiply what you have which is 3/7 * 3/1 giving you 9/7.

The cost to rent a paddle boat at the county park is $8 per hour plus a nonrefundable deposit of $10. The cost can be modeled by the function f(h) = 8h + 10, where
h represents the number of hours the boat is rented. Describe the graph of g(h) as it relates
to f(h) if the nonrefundable deposit increases to $15.

Answers

When the non-refundable fee increases to $15, the y-intercept is also increased to 15. The graph are parallel to each other but only touches the y-axis at 10 and 15 respectively

Linear Equation

Linear equations are equations of the first order. The linear equations are defined for lines in the coordinate system. When the equation has a homogeneous variable of degree 1 (i.e. only one variable), then it is known as a linear equation in one variable. A linear equation can have more than one variable.

Linear equations are generally represented in the form

y = mx + c

c = y-interceptm = slope

The y-intercept is the point at which the graph touches the y - axis

In the question, we are given an equation f(h) = 8h + 10

The slope and y - intercept here are 8 and 10 respectively.

However, when the non-refundable deposit is increased to 15, the y - intercept is increase by 5 units to becomes 15.

Given that x is a nonnegative number, a student conjectured that x + 3 < x2.
Which value of x is a counterexample to the student's conjecture?
A: x= -1/3
B: x= -3
C: x= 2
D: 3

Answers

Answer:

C (x = 2)

Step-by-step explanation:

Since x is a non-negative number, A and B are eliminated.

This leaves C and D.

C: x = 2,

2 + 3 < 2^2

5 < 4 is false.

So C would be a counterexample.

What is the length of NM?

Answers

Answer:

See below :)

Step-by-step explanation:

We know that these traingles are all similar. We can see the angle NMK is 60 degrees so we also know that JNK is 60 degrees. Now we know that all of the triangles are 30-60-90 triangles. JN is 3, so from the "leg opposite to 30 degree theorem", we know that NK is two times JN which is 6. Then from the same theorem, we know that NM is NK divided by the square root of 3

[tex]\frac{6}{\sqrt3}[/tex]

We can't have fractions that have irrational numbers in the denominator of a fraction so we multiply it by root3 over root3

[tex]\frac{6}{\sqrt3}[/tex] * [tex]\frac{\sqrt3}{\sqrt3}[/tex]

This then makes it 6 times root 3 over 3

[tex]\frac{6\sqrt3}{3}[/tex]

We then get [tex]2\sqrt{3}[/tex]

Complete a paragraph proof for: Given: -4k + 2(5k - 6) = 3k - 36 Prove: k=-8. can someone please help me ​

Answers

The value of k is proved to be -8

How to prove that the value of k is -8?

The equation is given as

-4k + 2(5k - 6) = 3k - 36

Open the bracket in the above equation

So, we have

-4k + 10k - 12 = 3k - 36

Collect the like terms in the above equation

So, we have

-4k + 10k - 3k = 12 - 36

Evaluate the like terms in the above equation

So, we have

3k = -24

Divide both sides of the above equation by 3

So, we have

k = -8

Hence, the value of k is proved to be -8
