A vendor sells hot dogs and bags of potato chips. A customer buys 3 hot dogs and 5 bags of potato chips for $9.50. Another customer buys 2 hot dogs and 5 bags of potato chips for $8.00. Find the cost of each item.

Answers

Step-by-step explanation:

3d + 5p=9.50

2d + 5p=8

1 hot dog cost $1.50

2 × 1.50 + 5p = 8

3 + 5p = 8

5p = 8 - 3

5p = 5

p = 1

Answer:

7. 24.25

8. 28.00111604 or 28

Step-by-step explanation:

30 +90 =120 180-120=60

Sin A = a/c, so a = cSin A. Also Cos A = b/c, so b = cCos A so Sin30=14/c=28

Cos30=b/28 b=24.25

now 14^2+24.25^2=c^2 which gives 28.00111604 or 28

Help ASAP

Answers

Answer:

Step-by-step explanation:

Answer:

(x, y) = (-16/5, 13[tex]\frac{1}{5}[/tex])

Step-by-step explanation:

4x + 9y = 24

x + y = 10 $\Rightarrow$ x = 10 - y

Substituting the value of x (second equation) into the first equation, we get:

4 * (10 - y) + 9y = 24

40 - 4y + 9y = 24

5y = -16

y = -16/5.

So, x = 10 - (-16/5) = 10 + 3[tex]\frac{1}{5}[/tex] = 13[tex]\frac{1}{5}[/tex]

Answer:

x = 9

Step-by-step explanation:

Perimeter of rectangle = 2(l+b) = 42

=> 2(x+3 + x)

=> 2 (2x + 3) = 42

=> 4x + 6 = 42

=> 4x = 42 - 6

=> 4x = 36

=> x = 36/4

=> x = 9

Hope it helps :)

Answer:

Formula = (l + b) x 2= 42 so answer = x=9

Step-by-step explanation:

l =x

b =x+3

( x+x+3) * 2 =42

2x +3 x 2 = 42

2x +3 = 42/2

2x +3 = 21

2x = 21 - 3 =18

x = 18/2

Answer:

c) [tex]h(t)=-16(t-1.5)^{2}+676[/tex]

Step-by-step explanation:

Each of the given equations is written in vertex form. This means that the vertex is written in the equation. The quadratic term (the term to the second degree), contains (x), and a value that is either added or subtracted to it. The additive inverse (meaning a number times negative one) of that number is the x-coordinate of the vertex. Therefore, the term inside the parenthesis is (-1.5). The constant is the y-coordinate of the vertex, and therefore it is 676. Since the object is being thrown off a cliff, gravity acts on it. The gravitational constant in feet per second is (-16), hence the coefficient of the quadratic term is (-16).

Answer:A. 20 B. 70 C.20 D. 70 E. 70

Step-by-step explanation:

Hope this helps!

a:20
b:70
c:20
d:70
e:110

Step by step:

E + 70 = 180 thus, E = 110

A + 70 = 90 thus, A = 20

A + B = 90 thus, B = 70; because A would be equal to 20

B + C = 90 thus, C = 20; because both sides are 90 degrees

E + D = 180 thus, D = 70; because E would be equal to 110

Renee is creating a diagram to prove that a certain triangle is a right triangle. In her diagram, she uses three white quadrilaterals that are squares. Which diagram could be the one that Renee is creating

Answers

Answer:

Option D

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. Types of triangles are right angled triangle, scalene triangle, equilateral triangle and isosceles triangle.

A right angled triangle is a triangle in which one of the angles is 90°. The side opposite the 90° is known as the hypotenuse while the remaining sides is known as the leg. Let us assume a right triangle with legs of a, b and a hypotenuse of c. Then using Pythagoras theorem:

c² = a² + b²

From the options, option d is the correct option.

For option D, the hypotenuse is c and one leg is a. Let x represent the second leg. Hence:

c² = a² + x²

x² = c² - a²

x = √(c² - a²)

Therefore the other leg would be √(c² - a²)

Anyone who has ever tried to make anything with these kinds of tools knows how limiting they are: if you hit a piece of wood it either splinters, cracks, or snaps. The same is true of rock or bone. Metals are fundamentally different from these other materials because they can be hammered into shape: they flow, they are malleable. Not only that, they get stronger when you hit them; you can harden a blade just by hammering it. And you can reverse the process simply by putting metal in a fire and heating it up, which will cause it to get softer. The first people to discover these properties ten thousand years ago had found a material that was almost as hard as a rock but behaved like a plastic and was almost infinitely reusable. In other words, they had discovered the perfect material for tools, and in particular cutting tools like axes, chisels, and razors. This ability of metals to transform from a soft to a hard material must have seemed like magic to our ancient ancestors. *** In 1961 Professor Richmond from Oxford University discovered a pit that had been dug by the Romans in AD 89. It contained 763,840 small two-inch nails, 85,128 medium nails, 25,088 large nails, and 1,344 extra-large sixteen-inch nails. The hoard was of iron and steel and not gold, which most people would have found bitterly disappointing. But not Professor Richmond. Why, he asked himself, would a Roman legion bury seven tons of iron and steel? The legion had been occupying the advance headquarters of Agricola in a place called Inchtuthil in Scotland. This was at the outer reaches of the Roman Empire, and their mission was to protect its border from what they saw as the savage tribes who threatened it: the Celts. The legion of five thousand men occupied the region for six years before retreating and, in the process, abandoning their fort. They made great efforts to leave behind nothing that could help their enemies. They smashed all food and drink containers and burned the fort to the ground. But they werent satisfied with this. In the ashes were the steel nails that had held the fort together, and they were far too valuable to be left to the tribes that had driven them out. Iron and steel were the materials that enabled the Romans to build aqueducts, ships, and swords; they allowed them to engineer an empire. Leaving the nails to their enemies would have been as useful as leaving a cache of weapons, so they buried them in a pit before marching south. Which line from the excerpt provides context that supports the meaning of the word malleable? a) metals are fundamentally different b) hammered into shape c) they flow d ) stronger when you hit them what was the first plan of goverment in north america.what this plan do HELP I NEED HELP ASAP During elections in a democracy, it is important that all citizens exercise their right todetermine their future by voting.The suffix -cracy means "form of government."
