Answer:

AB=15

Step-by-step explanation:

By looking at the figure, you will find that AB = AC-BC. Use this equation to solve:

[tex]AB=AC-BC\\AB=24-9\\AB=15[/tex]

AB = AC - BC

AB = 24 - 9 = 15

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: D

Step-by-step explanation:

This is a translation, so this means side lengths are preserved because a translation is a rigid motion. If all the side lengths are the same, then the perimeters must be the same.

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)

Based on the calculations, the approximate diameter of this circle is equal to 11.0 in.

Given the following data:

To determine the approximate diameter of this circle:

Mathematically, the circumference of a circle is given by the formula:

[tex]Circumference = \pi D[/tex]

Where:

Substituting the given parameters into the formula, we have;

[tex]35\frac{13}{21}=\frac{22}{7} D\\\\\frac{748}{21} =\frac{22D}{7} \\\\748\times 7=22D \times 21\\\\5236=462D\\\\D=\frac{5236}{462}[/tex]

D = 11.3 ≈ 11.0 in.

Step-by-step explanation:

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:

$4,560 × 3 = $13,680

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.

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%

Answer: D.

Step-by-step explanation:

round the numbers to 12,000 and 24, then multiply

Answer:

a) The volume of the pyramid 440.44 cube units

(b) No she doesn't

(c) The volume of the larger pyramid is 1,486.485 cube units

Step-by-step explanation:

The given parameters are;

The scale factor of the pyramids, S.F. = 2:3

The base area of the small pyramid,  = 110.11 square units

The height of the small pyramid, h₁ = 12 units

(a) The volume of a pyramid, V = (1/3) × Area of base × The height of the pyramid

Therefore;

The volume of the small pyramid, V₁ = (1/3) × 110.11 square units × 12 units

V₁ = 440.44 cube units

The volume of the small pyramid, V₁ = 440.44 cube units

(b) No she does not have to go through all the hard work again to find the volume of the larger pyramid

She only has to make use of the scale factor relationships of the two pyramid to calculate the volume of the larger pyramid

The volume scale factor = (The linear scale factor)³

(c) The linear scale factor of the pyramids = 2:3 = 2/3

Therefore;

The volume scale factor of the pyramids = (2/3)³ = 8/27

To find the volume of the larger pyramid, V₂, from the volume of the smaller pyramid, V₁, we multiply the volume of the smaller pyramid, V₁,  by 27/8 as follows;

V₂ = V₁ × (27/8)

Therefore;

The volume of the larger pyramid, V₂ = 440.44 cube units × (27/8) = 1,486.485 cube units

The volume of the larger pyramid, V₂ = 1,486.485 cube units.

Answer:

P + M = 30

700P + 200M = 15000

Number of laser printers = 18

Number of color monitors = 12

Step-by-step explanation:

Let P = number of laser printers

Let M = number of color monitors

Given total number of boxes = 30

⇒ P + M = 30

Given:

⇒ 700P + 200M = 15000

Rewrite P + M = 30 to make P the subject:

⇒ P = 30 - M

Substitute into 700P + 200M = 15000 and solve for M:

⇒ 700(30 - M) + 200M = 15000

⇒ 21000 - 700M + 200M = 15000

⇒ 500M = 6000

⇒ M = 12

Substitute found value for M into P = 30 - M and solve for P:

⇒ P = 30 - 12 = 18

Step-by-step explanation:

Welcome to 50 grams to ounces. If you have been wondering about how many ounces in 50 grams, then you are perfectly right here. 50 grams can also be written as 50 g, and the symbol for ounces is oz. In other words, this article is about the conversion of 50 g to oz, to the unit international avoirdupois ounce to be exact, but we also explain you the conversion into the international troy ounce. Read on to learn everything about 50 grams in ounces.

To change 50 g to oz divide the mass in grams by 28.349523125. The 50 grams to ounces formula is [oz] = [50] / 28.349523125. Thus, we get (all results rounded to 2 decimals):

50 g to oz = 1.76 oz

50 g to ounces = 1.76 ounces

50 grams to ounces = 1.76 oz

Fifty grams to ounces equal 1.76 international avoirdupois ounces, the unit used to measure grocery products (mass) in retail stores in the United States for example.

The result also applies to 50 g in oz for dry foods in bulk, but is not valid for liquids, whose volumes are measured in fluid ounces: 50 grams to ounces ≠ 50 grams to fluid ounces.

Finally, 50 grams to troy ounces results in 1.61 oz as the formula is [troy oz] = [50] / 31.1034768. Thus, 50 gram gold to ounces is 1.61 international troy ounces when converted.

Step-by-step explanation:

If one angle = 90 degrees, then the other 2 added together must also = 90.

There is only 1 answer to this, since the triangle is isosceles..

x + x = 90        Combine

2x = 90            Divide by 2

x = 90/2          

x = 45

So both acute angles = 45 degrees.
