What is the volume of this triangular prism?

182 m3
195 m3
210 m3
390 m3

Answer:

8.4

Step-by-step explanation:

To round to the nearest tenth, first go to the hundredth place, which in this case is a 3. If this is number is lower than 5, keep the tens place as it is, which is how it is in this problem.

Answer:

8.4

Step-by-step explanation:

The tenths is the first number to the right of the decimal. If the number to the right of the tenths digit is 5 or above you round it up, if it is less than 5 you round it down. In this case it is 3 which is less than 5 so you round it down to 8.4

Answer:

[tex]v = {210cm}^{3} [/tex]

Step-by-step explanation:

Formula for finding the volume of a triangular prism is given as:

[tex]v = \frac{1}{2} \times b \times h \times l[/tex]

where,

b = breadth = 7cm

h = height = 6cm

l = length = 10cm

Thus,

[tex]v = \frac{1}{2} \times 7cm \times 6cm \times 10cm[/tex]

[tex]v = \frac{1}{2} \times 420 {cm}^{3} [/tex]

[tex]v = \frac{ {420cm}^{3} }{2} [/tex]

[tex]v = {210cm}^{3} [/tex]

Answer:

When x = 4

Step-by-step explanation:

Division by zero is undefined. With real numbers, you are not allowed to divide by zero. Any value of x that causes the denominator to have a value of zero is not allowed. We need to find out which values of x cause the denominator to equal zero.

To do that, we set the denominator equal to zero and solve for x.

2x - 8 = 0

Add 8 to both sides.

2x = 8

Divide both sides by 2.

x = 4

Answer: The rational expression is undefined when x = 4

Check:

Let x = 4, and evaluate the denominator of the fraction.

2x - 8 = 2(4) - 8 = 8 - 8 = 0

By letting x = 4 in the denominator, the denominator does evaluate to zero causing an undefined value in the division. Therefore, our answer above is correct.

The dimensions of playing card is L = 10 centimeter and W=5 centimeter, If the playing card has an area of 50 square centimeter and a perimeter of 30 centimeters.

Step-by-step explanation:

The given is,

                  Playing card has an area of 50 square centimeters

                  A perimeter of 30 centimeters

Step:1

                 A playing card is in the shape of rectangle,

                 Formula for perimeter of rectangle is,

                                      [tex]Perimeter, P = 2(l+w)[/tex] .........................(1)

                 Formula for area of rectangle is,

                                             [tex]Area, A= lw[/tex]......................................(2)

                  Where, l - Length of rectangle

                             w - Width of rectangle

Step:2

                From the given values equation (1) becomes,

                                                       [tex]30 = 2(l+w)[/tex]              

                                                       [tex]\frac{30}{2}=(l+w)[/tex]      

                                                       [tex]15 =(l+w)[/tex]

                                                       [tex]w=15-l[/tex]  .............................(3)

                Width value in terms of length is calculated.

Step:2

                Equation (2) becomes,

                                                      [tex]50 = (15-l)(l)[/tex]

                                                      [tex]50= 15l -l^{2}[/tex]

                                      [tex]l^{2}-15l+50=0[/tex]

              Solving the above equation,

                                                          [tex]=10[/tex]

                                                       [tex]l=10 cm[/tex]

Step:3

                 Equation (3) becomes,

                                                       [tex]w=15-l[/tex]

                                                           [tex]=15-10[/tex]

                                                           [tex]=5[/tex]

                                                     w = 5 cm

Result:

           The dimensions of playing card is L = 10 centimeter and W = 5 centimeter, If the playing card has an area of 50 square centimeter and a perimeter of 30 centimeters.

Final answer:

By creating an equation system using the area and perimeter formulas for a rectangle, the dimensions of the playing card are found to be either 5 cm by 10 cm or 10 cm by 5 cm.

Explanation:

To determine the dimensions of a playing card given its area and perimeter, we need to set up an equation system based on the properties of a rectangle. Let's call the length L and the width W. The area (A) of a rectangle is A = L × W, which in this case is 50 sq cm. The perimeter (P) is P = 2(L + W) and is given as 30 cm.

From the perimeter, we can rearrange this to find L in terms of W:
30 cm = 2(L + W)
15 cm = L + W
L = 15 cm - W

Now, substituting L in the area equation gives us:
50 cm² = (15 cm - W) × W
This can be rearranged to form a quadratic equation:

0 = W² - 15W + 50

Factoring, we find:
0 = (W - 5)(W - 10)
So we have two solutions, W = 5 cm or W = 10 cm.

If we take W as the width, then L (the length) would be the other dimension, which would be 15 cm - W. So, we have two possible dimension pairs based on the standard card size: (5 cm by 10 cm) or (10 cm by 5 cm).

Answer:

8x+8

Step-by-step explanation:

The perimeter is all the sides added together:

3x+2+6x-1+7-x = 8x+8

The perimeter of the triangle in terms of x is expressed as 8 ( x - 1 ).

Given,

The sides of a triangle are 3x+2, 6x-1, and 7-x.

We need to express the perimeter of the triangle in terms of x.

It is given by:

Perimeter = sum of all three sides.

Find the sides of a triangle.

We have,

One side = 3x + 2

Second side = 6x - 1

Third side = 7 - x

Find the perimeter of the triangle.

Perimeter:

= one side + second side + third side

= (3x + 2) + (6x - 1) + (7 - x)

= 3x + 2 + 6x - 1 + 7 - x

= 3x + 6x - x + 2 - 1 + 7

= 8x + 8

Taking 8 common

= 8 ( x - 1 )

Thus the perimeter of the triangle in terms of x is expressed as 8 ( x - 1 ).

Answer:

m<1 = 135°, m<2 = 45°, m<3 = 135°, m<4 = 45°, m<5 = 135°, m<6 = 45°, m<7 = 135°

Step-by-step explanation:

We know that a straight line always gives us a measure of 180° total. This would mean 180° = m<8 + m<7. So, if we plug in the real value of m<8, we get 180 = 45 + m<7. From there, we can subtract 180 by 45, and we get 135° = m<7.

We know that vertical angles are congruent - so m<5 is the same as m<7 - making m<5 = 135° as well. This could also apply to m<8 and m<6, so m<6= 45°.

From there, we can also say that alternate interior angles are congruent to each other - meaning m<5 = m<3, and m<6 = m<4. So, m<3 = 135° and m<4 = 45°.

Alternate exterior angles are congruent too, which means m<8 = m<2, and m<7 = m<1. So, m<2 = 45° and m<1 = 135°.

In summary,

m<7 = 135° because angle subtraction.

m<5 = 135° and m<6= 45° because vertical angles are congruent.

m<3 = 135° and m<4 = 45° because alternate interior angles are congruent.

m<1 = 135° and m<2 = 45° because alternate exterior angles are congruent!

Hope this makes sense! Not sure if I explained it well.

^3(square root symbol) x^4 this is for radicals only

Step-by-step explanation:

If you are doing fractions then the correct answer would be x1 1/3

Explanation for ^3(square root symbol) x^4

When writing these in radicals simplified x^4/3 you put the denominator over your square root, and your numerator will be squared by your denominator. But your numerator must be to x as x is the constant. So ^3(square root symbol) x^4 = x^4/3

Explanation for x1 1/3

When simplifying fractions you take out the extra of the fraction and turn it into its own fraction, and the whole fraction you are left with, in this case being 3/3, you turn into a whole number, which is 1, and you add your left over fraction, 1/3, and put them together 1 1/3, but don't forget your x, x1 1/3

The expression 'x 4/3' can alternatively be written as the cube root of x to the fourth power, expressed as ∛[tex](x^4)[/tex]a mathematical context.

The statement x 4/3 is a mathematical expression which can be interpreted in different ways based on context.

If the intention is to write the expression x to the power of 4/3, it can be expressed as a radical, specifically as the cube root of x4.

The cube root operation can be represented by the radical symbol, so the alternative way to write it would be ∛(x4).

This would not be a Unit Conversion question. It is essential to understand that without further context, the expression is ambiguous and might represent other mathematical operations or concepts.

However, it does not seem to relate directly to any of the extraneous information provided.

The remainder when the 100th term of the Fibonacci sequence is divided by 8 is 3.

The Fibonacci sequence is a sequence where each term is the sum of the previous two terms. The sequence starts with 1, 1, and then continues with 2, 3, 5, and so on. To find the remainder when the 100th term of the sequence is divided by 8, we can calculate the terms of the sequence modulo 8 until we reach the 100th term.

We can see from the pattern that the terms modulo 8 repeat every 6 terms. Therefore, to find the remainder when the 100th term is divided by 8, we can calculate the remainder when 100 is divided by 6. 100 mod 6 = 4. So, the remainder when the 100th term of the Fibonacci sequence is divided by 8 is the same as the remainder when the 4th term is divided by 8, which is 3.

Answer:

  1278 × 4

Step-by-step explanation:

Apparently, a 4-digit number is being multiplied by a 1-digit number. We expect that the partial products are the result of multiplying single digit numbers with different place values.

So, 4000 = 1000 × 4 or 500 × 8

  800 = 200 × 4 or 100 × 8

We don't think 8 is the multiplier, because 500 and 100 have digits with the same place value multiplier (100).

Continuing, ...

  280 = 70 × 4

  32 = 8 × 4

The numbers being multiplied seem to be 1278 × 4.

2500÷6.25=400

Based on the random sample of 25 iPhones in which 4 were found to be defective, it is projected that approximately 400 iPhones in the total shipment of 2,500 would be defective.

The question is essentially asking for a projection based on a statistical sample. In this case, the sample is 25 iPhones, out of which 4 were found to be defective. This implies that, out of every 25 iPhones, we can expect approximately 4 to be defective.

To project this onto the entire shipment of 2,500 iPhones, we can use the proportion found in the sample. Divide the total number of iPhones by the sample size to find the number of 'samples' in the shipment: 2500 ÷ 25 = 100. Then multiply this by the number of defective iPhones found in the sample: 100 x 4 = 400.

So based on the sample, the manager can expect approximately 400 iPhones in the shipment to be defective.
