4 hours. 1 3/4 is about 2, and 2 1/4 rounds to 2. 1/4 would round to 0, but it would not affect the estimate's accuracy much because we rounded up by 1/4 on 1 3/4 already. Philipe spent about 4 hours on activities.

The equation to solve is:
[tex] \frac{x}{5}= \frac{4}{10} [/tex]
Step-by-step solution:
1) multiply both sides of the equation by 10:
[tex]10 \cdot \frac{x}{5} = 10\cdot \frac{4}{10}[/tex]
2) simplifying:
[tex]2x = 4[/tex]
3) dividing both terms by 2:
[tex]x= \frac{4}{2}=2 [/tex]
and the solution is x=2.

Hi there!

The Eqn. is :-

[tex]\dfrac {x}{5} = \dfrac {4}{10}[/tex]

=> x = [tex]\dfrac {4}{10}[/tex] × 5

=> x = [tex]\dfrac {4}{2}[/tex]

=> x = 2

Hence, x = 2

The flat surfaces of a 3D shape are called what? Faces Edges Vertices

Answers

The flat surfaces of a 3D shape are called faces

The flat surfaces of a 3D shape are called faces.

The faces serve as the two-dimensional polygonal areas that define the boundaries of a 3D object. In geometry, for instance, a cube is a common 3D shape that has six faces, each of which is a square. Each face is bordered by edges, which are the straight lines where two faces meet, and the corners of the faces are known as vertices (or vertex in singular form).

Examining various 3D shapes, such as the tetrahedron, which has four triangular faces, and the octahedron with its eight triangular faces, provides a clearer understanding of how faces constitute the polyhedron's shape.

Write an equation of the line that is perpendicular to y = −4x + 8 and passes through the point (5, 1)

Answers

Hello,

To start, we have to identify the slope of the perpendicular line. Perpendicular lines have opposite reciprocal slopes. Therefore, the slope of our new line will be 1/4.

Now, just substitute in the given point with our new slope and we can solve for B.

y = (1/4)x + b
1 = (1/4)5 + b
1 = 5/4 + b
-1/4 = b

Now that we have the slope and the y-intercept, we can put together our equation.

It is: y = (1/4)x - 1/4

Find the average rate of change between n = 2 and n = 4.

Answers

The average rate of change of the sequence from n = 2 to n = 4 is 1.5, which is determined by calculating the difference in sequence values for these n values and dividing by the difference in n.

The average rate of change of a function between two points reflects the function's slope between those points. To find the average rate of change of the sequence [tex]a_n = \frac{1}{2} (2)^{n - 1}[/tex]from n = 2 to n = 4, we calculate the differences in the sequence values corresponding to these n values and divide by the difference in n itself.

The value of a_n when n = 2 is [tex]a_2 = \frac{1}{2} (2)^{2 - 1}= 1.[/tex]The value of a_n when n = 4 is [tex]a_4 = \frac{1}{2} (2)^{4 - 1}[/tex]= 4.To find the average rate of change, use the formula: rate of change = [tex](a_4 - a_2)[/tex] / (4 - 2) = (4 - 1) / (4 - 2) = 3/2 = 1.5.

Therefore, the average rate of change between n = 2 and n = 4 for this sequence is 1.5.

Answers

hannah can make 2 quadrilaterals and 1 triangle.

Answer:

Step-by-step explanation:

Given that Hannah has 11 toothpicks that are the same length

When she uses only one toothpick for each side then we see that all sides would be equal whether quadrilateral or triangle.

Hence she can make equilateral triangles, rhombuses or squares out of these 11 toothpicks

Either one equilateral triangle, and 2 rhombuses, or one equil. triangle and 2 squares or 1 equil triangle with 1 square, 1 rhombus or 2 equil triangles with one square or rhombus

How do you tell a triangle is not a right triangle

Answers

You can tell when you cant draw an even L shaped figure at the intersects of the bottom and the side. 90 degrees. But there are many different ways that may make more sense. Happy to help:)

Hi! :)

So a right triangle is classified as a right triangle because it has one right angle. You can tell if it's not a right triangle by the angle measurements. If all the angles are above or below 90 degrees, it's not a right triangle. If one of the angles is 90 degrees, it's classified as a right triangle.

A bakery sells 6 bagels for $2.99 and 4 muffins for $3.29. What is the total cost in dollars for 4 dozens bagels and 16 muffins, not including tax? Need help trying figure how to start solving

Answers

24$ for 4 dozens of bagels
13.16$ for 16 muffins

Since a dozen has 12 in it you can multiply 2.99 by two since that's the cost for six. Then you multiply that amount by 4. For the muffins you need to multiply 3.29 by four. Finally, you take both of those products and add them together to find the total cost.

Barb is making a bead necklace. She strings 1 white bead, then 3 blue beads, then 1 white bead and so on. Write the numbers for the first eight beads that are white. What is a rule for the pattern?

Answers

Final answer:

In Barb's necklace pattern, white beads occur at position numbers 1, 5, 9, 13, 17, 21, 25, and 29. The rule for the pattern is that any white bead will appear at a position that is 4n + 1, where n is any non-negative integer.

Explanation:

The student's question involves determining the position numbers of the first eight white beads in a pattern and identifying a rule for this pattern. The pattern established by Barb is one white bead followed by three blue beads, which then repeats. To find the positions of the first eight white beads, let's enumerate the pattern until we have identified eight white beads.

WhiteBlueBlueBlueWhiteBlueBlueBlueWhite...

As we can see, the white beads appear in a consistent pattern at every fourth position in the sequence. Thus, by listing out the pattern, we can identify the first eight white beads' position numbers as follows:

1591317212529

The rule for the pattern can be described as follows: any white bead will be at a position number that is 1 more than a multiple of 4 (i.e., 4n + 1, where n is a non-negative integer).

Final answer:

The first eight white beads in Barb's necklace pattern are in positions 1, 5, 9, 13, 17, 21, 25, and 29. The rule for the pattern is 4n - 3 for the nth white bead.

Explanation:

Barb is making a bead necklace with a repeating pattern: 1 white bead, followed by 3 blue beads, and then the pattern repeats. To determine the numbers for the first eight beads that are white, we can examine the pattern more closely. Since the pattern begins with a white bead and every white bead is followed by three blue beads, we can deduce that it takes 4 beads in total to complete one cycle of the pattern (1 white + 3 blue).

The positions of the first eight white beads are as follows: 1st, 5th, 9th, 13th, 17th, 21st, 25th, and 29th. The rule for this pattern can be expressed as follows: To find the position of any white bead in the sequence, you can use the formula 4n - 3, where n represents the nth white bead in the sequence.

For example, to find the position of the third white bead, we substitute n with 3 into our formula: 4 * 3 - 3, which equals 9. Therefore, the third white bead is the 9th bead in the overall pattern.

Place the following temperatures in order from coldest to hottest: -8°C, 10°C, -5°F, 40°F

Answers

To solve this problem, you should first convert all temperatures to one temperature scale. I'll use the formula to convert Fahrenheit to Celsius.
It is C = 5/9(F - 32), where F is the degrees Fahrenheit.

Let's start converting.

C = 5/9(-5 - 32)
C = 5/9(-37)
C = -185/9
C = -20.6°

C = 5/9(40 - 32)
C = 5/9(8)
C = 40/9
C = 4.4°

Now let's arrange them from least to greatest:
-20.6°C, -8°C, 4.4°C, 10°C.

Answer:
-5°F, -8°C, 40°F, 10°C.
