A model skyscraper is made with a scale of 1 inch to 75 feet. What is the height of the model if the height of the building is 1,395 feet?

Answers

Answer:

18.6 inches

Step-by-step explanation:

As we have the scale between the model and the real skyscraper, and we also have the height of the real building, to find the height of the model we just need to use a rule of three:

1 inch -> 75 feet

x inches -> 1395 feet

x*75 = 1*1395

x = 1395 / 75

x = 18.6 inches

The height of the model skyscraper is 18.6 inches.

c) 1. Distributive Property 2. Combine like terms 3. Addition Property of Equality 4. Division Property of Equality

Step-by-step explanation:

4x + 1/2(10x − 4) = 6

4x + 5x − 2 = 6 distirbuted 1/2 to 10x - 4

9x − 2 = 6 combinded like terms: x

9x = 8 addtion to the right side with 2

What is a linear equation?

It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.

If in the linear equation one variable is present then the equation is known as the linear equation in one variable.

We have the equation:

[tex]\rm 4x+\frac{1}{2} (10x-4)=6[/tex]

4x + 5x -2 = 6 (Multiplication proeprty of equality or Distributive property)

9x - 2 = 6 (combine like term)

9x = 8 (addition property of equality)

x = 8/9 (division property of equality)

Thus, the justifications are 1. Distributive Property 2. Combine like terms 3. Addition Property of Equality 4. Division Property of Equality options third and fourth is correct.

Rectangle A measures 3cm by (8x - 7)cm and rectangle B measures 4cm by (5x + 2)cm. Area of both rectangles is equal. Create the equation and find the value of x.

please help me i will mark you brainliest

Answers

Answer:

Equation: 3 (8x - 7) = 4 (5x + 2)

Value of x =7.25 cm

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Area of a rectangle: width x length

Replacing with the values given:

Area A = 3 (8x - 7)

Area B = 4 (5x + 2)

Since both areas are equal:

Area A = Area B

So:

3 (8x - 7) = 4 (5x + 2)

Solving for x:

24x -21 = 20x+8

24x-20x =8+21

4x =29

x =29/4=7.25 cm

The bottom part of this block is a rectangular prism. The top part is a square pyramid. You want to cover the block entirely with paper. How much paper do you need? Use a pencil and paper to explain your reasoning.

Also please look at the attachment.

Answers

Answer:

total paper required = 57 cm²

Step-by-step explanation:

given data

slant height b = 4 cm

base side h = 3 cm

block height h1 = 2 cm

solution

we get surface area of right squared pyramid by add here areas of all 4 triangles that is express as

area = 4 × Area of Triangles

area = 4 × [tex]\frac{bh}{2}[/tex]

area = 4 × [tex]\frac{4\times 3}{2}[/tex]

area = 24 cm²

and

surface are of the box is equal to the area of its 4 side faces + base

area = 4 × ( h × h1 ) + h²

area = 4 × ( 3 × 2 ) + 3²

area = 24 + 9

area = 33 cm²

so total paper required = 24 + 33

so total paper required = 57 cm²

The area of the base of a triangular pyramid with faces that are equilateral triangles is 64 ft squared. Can you find the surface area of the pyramid? Explain. Here are the choices
A. No, because the area of the base of a pyramid is not related to the area of its faces, so the surface area cannot be found without more information.

b. No, because the base of a pyramid with equilateral triangle faces does not necessarily have the same area as its equilateral faces.

C.Yes, because the area of the base of a triangular pyramid with equilateral triangles for faces is the same as the area of each face.

D.Yes, because the area of the base will be the edge length of each face, which can be used to find the area of each face

Answers

Answer:

Step-by-step explanation:

Yes, because the area of the base of a triangular pyramid with equilateral triangles for faces is the same as the area of each face.

Answers

Answer:

-20

Step-by-step explanation:

because if you put -20 over 4, that simplifies out to -5

Answer:

x= -20

Step-by-step explanation:

To solve this problem, we have to get x by itself.

x/4= -5

x is being divided by 4. To reverse this, multiply both sides by 4, because multiplication is the opposite of division.

4*(x/4)=(-5)*4

The 4s on the left cancel, so we are left with:

x=-5*4

x=-20

To check our solution, we can substitute -20 back in for x.

x/4=-5

-20/4=-5

-5= -5

This is true, so we know that -20 is the solution.

(40 POINTS)What structural adaptation of the A. cristatus lizard helps them in the water?The Amblyrhynchus, a remarkable genus of lizards, is confined to this archipelago; there are two species, resembling each other in general form, one being terrestrial and the other aquatic. This latter species (A. cristatus) was first characterized . . . from its short, broad head, and strong claws of equal length, that its habits of life would turn out very peculiar, and different from those of its nearest ally, the iguana. It is extremely common on all the islands throughout the group, and lives exclusively on the rocky sea-beaches, being never found . . . even ten yards in-shore. It is a hideous-looking creature of a dirty black colour, stupid, and sluggish in its movements. The usual length of a full-grown one is about a yard, but there are some even four feet long; a large one weighed twenty pounds: on the island of Albemarle, they seem to grow to a greater size than elsewhere. Their tails are flattened sideways, and all four feet partially webbed. They are occasionally seen some hundred yards from the shore, swimming about; and Captain Collnett, in his voyage says, They go to sea in herds a-fishing, and sun themselves on the rocks; and may be called alligators in miniature. It must not, however, be supposed that they live on fish. When in the water, this lizard swims with perfect ease and quickness, by a serpentine movement of its body and flattened tailthe legs being motionless and closely collapsed on its sides. A seaman on board sank one with a heavy weight attached to it, thinking thus to kill it directly, but when an hour afterwards, he drew up the line, it was quite active. Their limbs and strong claws are admirably adapted for crawling over the rugged and fissured masses of lava, which everywhere from the coast.

All day he hung round the cove or upon the cliffs with a brass telescope; all evening he sat in a corner of the parlour next the fire and drank rum and water very strong. Mostly he would not speak when spoken to, only look up sudden and fierce and blow through his nose like a fog-horn; and we and the people who came about our house soon learned to let him be. Every day when he came back from his stroll he would ask if any seafaring men had gone by along the road. At first we thought it was the want of company of his own kind that made him ask this question, but at last we began to see he was desirous to avoid them. When a seaman did put up at the Admiral Benbow (as now and then some did, making by the coast road for Bristol) he would look in at him through the curtained door before he entered the parlour; and he was always sure to be as silent as a mouse when any such was present.

Often enough when the first of the month came round and I applied to him for my wage, he would only blow through his nose at me and stare me down, but before the week was out he was sure to think better of it, bring me my four-penny piece, and repeat his orders to look out for the seafaring man with one leg.
