Answer:

Lateral surface area - The sum of surface areas of all sides except the top and bottom face of solid is defined as the lateral surface area of a solid. So the lateral surface area (L.S.A) of the cuboid is = 2(lh+bh)=2h(l+b)

Answer:

Lateral surface area of a cuboid = 2h(l + w)

where w = width, l = length and h = height

Step-by-step explanation:

Lateral Surface Area = Total Surface Area - Area of top and bottom faces

Let w = width

Let l = length

Let h = height

Lateral Surface Area = 2(lw + wh + lh) - (2 × l × w)

                                  = 2lw + 2wh + 2lh - 2lw

                                  = 2lh + 2wh

                                  = 2h(l + w)

Answer:

-3, 0, 0.5, and 3

Answer: w=0

Step-by-step explanation:

Step 1 Solve by distributing 0.15w+0.15\cdot2=0.3+0.2w

Simplify the arithmetic 0.15w+0.3=0.3+0.2w

Step 2 Subtract 0.2w from both sides 0.15w+0.3-0.2w=0.3+0.2~w-0.2w

Group like terms: 0.15w-0.2w+0.3=0.3+0.2w-0.2w Simplify the arithmetic -0.05w+0.3=0.3+0.2w-0.2w Group like terms -0.05w+0.3=0.2w-0.2w+0.3 Simplify the arithmetic -0.05w+0.3=0.3

Step 3 Subtract 0.3 from both sides -0.05w+0.3-0.3=0.3-0.3 Simplify the arithmetic -0.05w=0.3-0.3 Simplify the arithmetic -0.05w=0 Isolate the X

then equals w=0

Answer:

P ( A ∩ B ) = 7

Step-by-step explanation:

→ State the formula

P ( A ∪ B ) = P ( A ) + P ( B ) - P ( A ∩ B )

→ Substitute in the numbers

23 = 13 + 17 - P ( A ∩ B )

→ Solve

P ( A ∩ B ) = 7

Answer:

He needs more bananas. ([tex]\frac{10}{12}+\frac{9}{12}[/tex])

Step-by-step explanation:

Find the least common multiple for both denominators.

For 6 and 4 in the denominators, their L.C.M is 12.

Cup of mashed bananas:

Multiply both the numerator and denominator by 2.

[tex]\frac{5}{6} = \frac{10}{12}[/tex]

Cup of mashed strawberries:

Multiply both the numerator and denominator by 3.

[tex]\frac{3}{4} = \frac{9}{12}[/tex]

Since the denominators are now the same, we can compare them in the same ratio.

[tex]\frac{10}{12} > \frac{9}{12}[/tex]

Therefore he needs [tex]\frac{1}{12}[/tex] more mashed bananas than mashed strawberries.

To repay this loan in three years we must make annual payments of $23,560.

To calculate the payments that we must make each year, taking into account the 8% interest, we must carry out the following operations:

To calculate the interest equivalent to 8%:

So, to calculate the total per year that we must pay, we must add both values:

Finally, to know how much we pay in total for the interest on the loan, we multiply the value of the interest by the years that the loan lasted:

Answer:

[tex]\sf y=-\frac{5}{2}x+\frac{27}{2}[/tex]

Step-by-step explanation:

given equation:

[tex]\sf y = \frac{2}{5} x -1[/tex]

using the formula: y = mx + b

Here, we can determine 2/5 is the slope

if perpendicular: -1/m → -1/2/5 → -5/2

using the formula:

[tex]\sf y - y1 = m ( x - x1)[/tex]

[tex]\sf y - 6 = -\frac{5}{2} ( x - 3 )[/tex]

[tex]\sf y - 6 = -\frac{5}{2} x - \frac{15}{2}[/tex]

[tex]\sf y = -\frac{5}{2} x + \frac{15}{2} +6[/tex]

[tex]\sf y=-\frac{5}{2}x+\frac{27}{2}[/tex]

The percentage of women who spend less than $160.00 is 68.03%.

The term "standard deviation" refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.

Given:

standard deviation = $29.44.

A survey found that women spend on average $146.21

so, the z- score

= 160 - 146.21 / 29.44

= 13.79/ 29.44

= 0.4684

Now, P( z< 0.4684)= 0.6803= 68.03%

Parallel lines are lines that have equal slope

It is true that the two lines are parallel

The equations of the two lines are given as:

y = 5x + 1 and 2y - 10x + 3 = 0

Both equations are linear equations, and a linear equation is represented as:

y = mx + b

Where m represents the slope.

For equation L1, the slope is:

m = 5

For equation L2, we have:

[tex]2y - 10x + 3 = 0[/tex]

Divide through by 2

[tex]y - 5x + 1.5 = 0[/tex]

Make y the subject

[tex]y = 5x - 1.5[/tex]

This means that the slope of equation L2 is also 5

When the slopes are equal, then the lines are parallel

Hence, the two lines are parallel
