Answer:

C) 104 units^3

Step-by-step explanation:

The formula for volume in a rectangular prism is V=lwh

There are three total rectangular prisms, so take the volume of each individual prism and add them together to get the total volume.

smallest: V=(2)(2)(4) = 16

Medium: (2)(2)(6) = 24

Largest: (2)(2)(16) = 64

Add it together: 16+24+64= 104

Your answer is 104 units^3

Answer:

The answer is 19,75 people / km2

Step-by-step explanation:

Let's say that the total area of the city is 4 kilometer squares. In that case, the east of the river, which is 25% of the city, is 1 kilometer square. This means that the population is 28 on the east side of the city

The west side of the city is 3 kilometer squares, which means the population is 17 x 3 = 51.

The total population of the city is 51 + 28 = 79 and the total area is 4 kilometer squares. So the population density of the city as a whole is

79 / 4 = 19,75 people per kilometer square.

Answer:12

Step-by-step explanation:37=3x+1

Answer:

First, you get both of them with same denominator:

3/7 and 2/3 => 9/21 and 14/21, however, there are only 4 rational numbers between 9/21 and 14/21.

The solution is that you can raise the denominator 2 times:

9/21 and 14/21 => 18/42 and 28/42

Now you can select : 19/42, 20/42, 21/42, 22/42, 23/42. They are a group of  5 rational numbers you are looking for.

Answer:

A = 222 in²

Step-by-step explanation:

A = 2(wl+hl+hw)             Use this equation to find the surface area of the rectangular prism

A = 2(5*12 + 3*12 + 3*5)    Multiply

A = 2(60 + 36 + 15)            Add in the parentheses

A = 2(111)                             Multiply

A = 222 in²

Answer:

slant length = 35 cm

Step-by-step explanation:

A right cone has the vertex directly above the center of the base . The surface area of the right cone can be represented below.

surface area = πr(r + l)

where

r  = radius

l = slant height/length

surface area = πr(r + l)

r = 10/2 = 5 cm

surface area = 628 cm²

Therefore,

628 = π × 5(5 + l)

628 = 5π(5 + l)

628 = 25π + 5πl

628 = 25 × 3.14 + 5 × 3.14 × l

628 = 78.5 + 15.7l

628 - 78.5 = 15.7l

549.5 = 15.7l

divide both sides by 15.7

l = 549.5/15.7

l = 35 cm

slant length = 35 cm

Answer:

35cm

Answer:

The fixed amount Gi earns for each television he sells is $ 55.

Step-by-step explanation:

If Gi sold 14 televisions and earnt a total of $1,190, then for each television that was sold he earnt:

per tv = total earnt/total sold

per tv = 1190/14 = 85

Since he sold all these televisions with warranty, then he earned "x + 30" per each tv sold, since he got the bonus from the warranty. Therefore the fixed amount he earns per tv is:

x + 30 = 85

x = 85 - 30

x = 55

The fixed amount Gi earns for each television he sells is $ 55.

he needs to buy a total of 81 tires to finish the job

Answer:

94 tires

Step-by-step explanation:

He would be able to change 5 cars, but would need to buy 94 more tires.

I divided 22 by 5 and got 5.5. Then, I subtracted 28 minus 5, and got 23 times that by 4 and got 92 but you need to add the extra 2 tires.

Answer:

Carlos bought 80 feet of wire for ​$17.60.

Then the price for 1 feet of wire is 17.6/80 = 0.22

=> 30 feet of wire would cost: 30 x 0.22 = 6.6

Answer:

Step-by-step explanation:

A population parameter describes an entire population; a particular characteristic of an entire population. A value that describes the entire population. In this context, the population parameter is looking into the average ages of fathers when they had their first child, but this value is not given. The mean given here is the sample statistic.

Since, the population studied here is a very large population (all fathers), you have a statistic. But sometimes, if the population is very small and groups are small enough to measure, you have a parameter.

First we must calculate, for each tree the increment for each year:

bur oak:

Initial: 25.5 ft

1 year = 25.5 + 1.5 = 27

2 year = 27 + 1.5 = 28.5

3 year = 28.5 + 1.5 = 30

4 year = 30 + 1.5 = 31.5

5 year = 31.5 + 1.5 = 33

 hickory:

Initial: 30 ft

1 year = 30 + 1.5 = 31.5

2 year = 31.5 + 1.5 = 33

3 year = 33 + 1.5 = 34.5

4 year = 34.5 + 1.5 = 36

5 year = 36 + 1.5 = 37.5

Year  |  bur oak (ft)  |  hickory (ft)

  0              25.5              30

  1                 27               31.5

  2               28.5              33

  3                30               34.5

  4               31.5               36

  5                33               37.5

Answer:

No, the correct answer is -4

Step-by-step explanation:

-2 x (5 - 3)

(5 - 3)= 2

-2 x 2= -4

-4

Chase is not correct because the product of -2 and 2 is not 4 but the product of -2 and 2 is -4

From the question,

The expression Chase simplified is–2 ×­ (5 – 3).

First, we will simplify this expression properly and then check if Chase is correct or not.

To simplify the expression –2 ×­ (5 – 3)

First, we will evaluate the expression in the bracket

The expression in the bracket is 5 - 3

5 -3 = 2

Therefore, the expression –2 ×­ (5 – 3) becomes

–2 ×­ (2) = –2 ×­ 2

Now, we will complete the simplification by evaluating –2 ×­ 2

–2 ×­ 2 = -4

∴ Simplifying the expression –2 ×­ (5 – 3) gives -4

Now, to determine if Chase is correct or not, we will compare answers.

Since Chase found –2 ×­ 2 = 4, Chase is not correct because –2 ×­ 2 = –4. He did not add the negative sign.

Hence, Chase is not correct because the product of -2 and 2 is not 4 but the product of -2 and 2 is -4

Answer:

5. 34°

6. 29.7

Step-by-step explanation:

5. Using sine law

25/sin(93) = 14/sin(C)

sin(C) = 0.5592325395

C = 34.00273934°

6. Using cosine law

AC² = 23.2² + 18.1² - 2(23.2)(18.1)cos(91)

AC² = 880.507229

AC = 29.67334206

Answer:

5. m∠C ≈ 34°

6. AC ≈ 29.7 metres

Step-by-step explanation:

5. We need to use the Law of Sines here, which says that for a triangle with sides a, b, and c and angles A, B, and C:

[tex]\frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC}[/tex]

Here, a = 25, ∠A = 93°, and c = 14, so we want to find ∠C:

[tex]\frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC}[/tex]

[tex]\frac{25}{sin93} =\frac{14}{sinC}[/tex]

sinC ≈ 0.56

∠C ≈ 34°

6. We need to use the Law of Cosines here, which says that for a triangle with sides a, b, and c and angles A, B, and C:

[tex]c^2=a^2+b^2-2abcosC[/tex]

[tex]b^2=a^2+c^2-2accosB[/tex]

[tex]a^2=b^2+c^2-2bccosA[/tex]

Here, a = 23.2, c = 18.1, ∠B = 91°, and b = x. We want to find b, so:

[tex]b^2=a^2+c^2-2accosB[/tex]

[tex]x^2=23.2^2+18.1^2-2*23.2*18.1*cos(91)[/tex] ≈ 880.5

x ≈ 29.7 metres

Rectangular prism:

length times width x height

Triangular prism:

(a+b+c) h

Answer:

400 cubic cm

Step-by-step explanation:

Given that base is square and is side is 10 cm

area of square is given by side^2

Thus, area of base of cuboid  = [tex]10^2[/tex] square cm = 100 sq. cm

We know volume for any cuboid is area of base * height

height is 4cm

thus, volume of cuboid = area of base of cuboid * height

                                     = 100 * 4 cubic cm = 400 cubic cm

Volume of cuboid is 400 cubic cm.

Unit is cubic cm

The volume of square based cuboid is [tex]400cm^{3}[/tex].

Given that, base is square and side of base is 10 cm.

Height of the square-based cuboid.is 4cm.

Area of base = [tex](side)^{2}=(10)^{2}=100cm^{2}[/tex]

Volume of the cuboid is multiplication of base area and height of the cuboid.

  [tex]Volume=100*4=400cm^{3}[/tex]

Hence, the volume of square based cuboid is [tex]400cm^{3}[/tex].
