Answer 1

Step-by-step explanation:

that is a large gift. wow ! you have a lucky teacher ...

the surface of a block consists of 6 (3 pairs of) areas :

front and back

left and right

top and bottom

you know that the area of a rectangle is length × width ?

so,

front and back are

2× 9×13.5 = 18×13.5 = 243 m²

let and right are also

2× 9×13.5 = 243 m²

top and bottom are

2× 9×9 = 2 × 81 = 162 m²

so, for the whole package you need

243 + 243 + 162 = 648 m²

the money for that amount of wrapping paper alone would be way more than I ever spent on a teacher in my life ...

What is the exponential function for the amount of Carbon-10 after t hours?

The function is given by:

[tex]A(t) = 140(0.5)^{\frac{t}{19.255}}[/tex]

Solving for t, we have that:

[tex](0.5)^{\frac{t}{19.255}} = \frac{A(t)}{140}[/tex]

[tex]\log{(0.5)^{\frac{t}{19.255}}} = \log{\frac{A(t)}{140}}[/tex]

[tex]\frac{t}{19.255} = \frac{\log{\frac{A(t)}{140}}}{\log{0.5}}[/tex]

[tex]t = 19.255\frac{\log{\frac{A(t)}{140}}}{\log{0.5}}[/tex]

In item A, we have that A(t) = 123, hence:

[tex]t = 19.255\frac{\log{\frac{123}{140}}}{\log{0.5}}[/tex]

Francine has a picture with a length its width. She wants to enlarge the picture to have an area of 375 in2. What will the dimensions of the enlarged picture be? Model the scenario and solve. Then, explain in at least one sentence your solution and include the reasonableness of your solution.

Answers

Answer:

25 in x 15 in

Step-by-step explanation:

Given:

Length = 3/5 the widthArea = 375 in²

Let width = [tex]x[/tex]

Therefore, length = 3/5 [tex]x[/tex]

First create an equation for the area of the picture based on the given information for its width and length:

[tex]\begin{aligned} \implies \textsf{Area of original picture} & = \sf width \times length\\& = x\left(\dfrac{3}{5}x\right)\\& = \dfrac{3}{5}x^2\end{aligned}[/tex]

We are told the area of the enlarged picture is 375 in².  Therefore, substitute this into the equation and solve for [tex]x[/tex] to find the width of the enlarged picture:

[tex]\begin{aligned}\textsf{Area} & = 375\\ \implies \dfrac{3}{5}x^2 & = 375\\ x^2 & =375 \cdot \dfrac{5}{3}\\ x^2 & =625\\ x & = \sqrt{625}\\ x& = 25\end{aligned}[/tex]

Therefore, the width of the enlarged picture is 25 in.

Substitute the found value of [tex]x[/tex] into the expression for length to find the length of the enlarged picture:

[tex]\begin{aligned}\sf Length & = \dfrac{3}{5}x\\\\\implies \sf Length & = \dfrac{3}{5}(25)\\\\& = 15\: \sf in\end{aligned}[/tex]

Therefore, the dimensions of the enlarged picture are 25 in x 15 in.  The width is 25 in and the length is 15 in, as the length is 3/5 of the width.

4.5:2.25 in n:1 how would i solve this

Answers

The required ratio is 2:1.

We have given that,

4.5:2.25

Since we have given that

We need to find the ratio in the form of n:1.

What is the ratio?

A ratio indicates how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six. Similarly, the ratio of lemons to oranges is 6:8 and the ratio of oranges to the total amount of fruit is 8:14.

so, it becomes,

You have two sticks. each stick has one blue side and one pink side. you throw the sticks 10 times and record the results. use the table to find the experimental probability of the event.
1. tossing 2 pink
2. tossing 1 blue and 1 pink
3. not tossing all pink
outcome | frecuency
2 blue | 1
2 pink | 3
1 blue, 1 pink | 6

Answers

Answer:

1. 30%, 2. 60%, 3. 70%

Step-by-step explanation:

According to table the total frequencies is:

1 + 3 + 6 = 10

Probability = Favorable outcome frequency / total frequency

Find each probability according to equation above:

1. P(2 pink) = 3/10 = 30%

2. P(blue and pink) = 6/10 = 60%

3. P(not all pink) = (10 - 3)/10 = 7/10 = 70%

The experimental probability of the event are: 3/10; 3/5; 7/10.

Experimental probability

Frequencies=1 + 3 + 6

Frequencies = 10

Hence:

Tossing 2 pink:

P(2 P) = 3/10

P(2 P) =30%

Tossing 1 blue and 1 pink:

P(B and P) = 6/10

P(B and P)=60% or 3/5

Not tossing all pink:

P(not all P) = (10 - 3)/10

P(not all P)= 7/10

P(not all P)=70%

Therefore the experimental probability of the event are: 3/10; 3/5; 7/10.

What table represents a linear function

Answers

Considering the constant rate of change, it is found that table 1 represents a linear function.

What is a linear function?

A linear function is modeled by:

y = mx + b

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

From the concept of the slope, we have that the rate of change of a linear function is constant, that is, when x changes by 1, y has to change always by the same amount, which happens in table 1, with a constant rate of change of 1/2 = 0.5.

Through a regular hexagon whose base edge is 8cm and whose height ii 12cma hole in the shape of the right prism with ots end being rhombus with diagonals of 6cm and 8cm is drilled find the total surface area and volume of the remaining soild?

Answers

The total surface area of the remaining solid is 48(4+✓3) centimeters square.

How to calculate the surface area?

Through a regular hexagonal prism whose base edge is 8 cm and the height is 12 cm, a hole in the shape of a right prism.

The formula for the total surface area will be:

= Total surface area=2(area of the base)+ parameter of base × height

where,

Height= 8cm

Parameter of base=12(2) = 24

Area of the base= ✓3/4×4² = 64✓3/4

The surface area of the remaining solid will be:

= 2(64✓3/4) + 24 × 8

= 2(64✓3/4 + 192

With the hole is a rhombus prism with the following parameters:

diagonal 1 = 6, diagonal 2 = 8, height = 12

The volume is:

V1 =0.5 × d1 × d2 × h

V1 = 0.5 × 6 × 8 × 12

V1 = 96

The dimensions of the hexagonal prism are:

Base edge (a) = 8

Height (h) = 12

The volume is

V2 = (3✓(3)/2)a²h

V2 = (3✓3)/2) × 8² × 12

V2 = 1152✓3

The remaining volume is

V = V2 -V1

Donna is making a cookie recipe that calls for 1 ¾ cups of sugar. However, when she

goes to take out the measuring cups she can only find the one-half cup measuring cup. How many one-half cups will she need to fill to get the correct amount of sugar for her cookie recipe?

Answers

Answer:

  3 and 1/2 half-cups

Step-by-step explanation:

We are asked to find the number of half-cups that will equal 1 3/4 cups.

__

Let the desired number be represented by n. Then we require ...

  n × 1/2 = 1 3/4 . . . . some number of 1/2-cups will give 1 3/4 cups

Using a common denominator, we have ...

  n × 2/4 = 7/4

Multiplying by the inverse of the coefficient of n gives ...

  n × 2/4 × 4/2 = 7/4 × 4/2

  n = 7/2 = 3 1/2 . . . . . simplify

That is, Donna can measure 1 3/4 cups of sugar by using her 1/2-cup measure 3 times, and filling it half-full for the final 1/4 cup she needs.

She needs 3 1/2 half-cups to get the correct amount.
