Answers

Answer:

3x+4y= 12.5-----------1

3x+2y= 8.5------------2

Step-by-step explanation:

Given data

let cheese pizza be x and  mushroom pizza be y

Hence

3x+4y= 12.5-----------------------1

also

3x+2y= 8.5--------------------------2

Hence the systems of the equation is given as

3x+4y= 12.5-----------1

3x+2y= 8.5------------2

A typical airplane flies at an altitude of 38,000 feet. Part A: Write an integer to represent an airplane's altitude.

Answers

Answer:

+ 38,000

Step-by-step explanation:

Given that:

Altitude of airplane = 38,000

The altitude of an object such as airplane in this scenario refers to the height of the airplane above sea level. The sea level is represented as a zero point (mid level) such that distance below are negative and those above are positive.

Hence, at an altitude of 38000 feets, altitude of airplane can be represented as +38,000 feets.

Combine the like terms 4x+ 17x + 5y + 19 - 28b + 48y +87a - 24x​

Answers

Answer: -3x + 53y + 19 + (-28b) + 87a

First off, you need to circle every single thing on this expression, including the math symbols. So in order to do that, circle the symbols with the number behind:

19 - 28b -> (19) (-28b)

All of your numbers should end up like this:

(4x) (17x) (5y) (19) (-28b) (48y) (87a) (-24x)

Next, place an addition symbol in between all of them.

4x + 17x + 5y + 19 + (-28b) + 48y + 87a + (-24x)

Then, rearrange the numbers with the same variable (ex. a in “87a” is the variable), and the numbers without a variable as-well.

(4x + 17x + (-24x)) + (5y + 48y) + (19) + (-28b) + 87a

Finally, add all of the variables with the same letter with each other. You also need to add the numbers without one but since 19 is the only number without a variable in this expression you don’t add it to anything.

Your answer should come out to this:

-3x + 53y + 19 + (-28b) + 87a

Step-by-step explanation:

Using Trigonometry,

tan33° = Opposite/Adjacent = GF/DF.

Therefore GF = DF * tan33°

= 235tan33° = 152.6.

Angle GEF = Angle EDG + Angle DGE

= 33° + 34° = 67°. (Exterior Angle Theorem)

Using Trigonometry,

sin67° = Opposite/Hypotenuse = GF/EF.

Therefore EF = GF / sin67°

= 152.6 / sin67° = 165.8.

Hence the answer is the 1st option.

Answer:

the answer is A. GF =152.6 and EG=165.8

GF= 235*(tan(33))

EG= 152.6/(sin(67))

Multiply the second equation by 2

Solution: [tex](-\frac{45}{11},\frac{29}{11})[/tex]

Step-by-step explanation:

1) In order to use the elimination method to solve systems of equations, you must first multiply one or both of the equations so that the coefficients of a pair of terms with matching variables share the same number, but have opposite signs.

In this case, the y terms must fit that requirement. The y term in the first equation is 2y and the one in the second equation is -y. They already have opposite signs, one positive and other negative, so we just need -y to be -2y. So, in order to do that, multiply by 2.

2) After multiplying the whole second equation by 2, you will get [tex]8x - 2y = -38[/tex]. Now, add the the two equations together, eliminate the y terms, and isolate x to find its value.

3) Then, substitute that x value back into one of the equations to receive the y-value.

To better explain these steps, I attached pictures below.

At Taco Bell, I made a large purchase of 13 items that cost a total of $28.17. If Chicken Burritos cost $1.89 each and a Cheesy Gordita Crunch costs $2.49, determine how many of each that I purchased.

Answers

Answer:

Number of Chicken Burritos purchased=7

Number of Cheesy Gordita Crunch purchased=6

Step-by-step explanation:

Let x be the number of Chicken Burritos  and y be the number of Cheesy Gordita Crunch.

Total number items purchased=13

Total cost of 13 items=$28.17

Cost of each Chicken Burritos=$1.89

Cost of each Cheesy Gordita Crunch=$2.49

We have to find number of each items purchased.

According to question

[tex]x+y=13[/tex].....(1)

[tex]1.89x+2.49y=28.17[/tex]...(2)

Equation (1) multiply by 2.49 and  then subtract equation (2) from (1)

[tex]0.6x=4.2[/tex]

[tex]x=\frac{4.2}{0.6}[/tex]

x=7

Substitute x=7 in equation (1)

[tex]7+y=13[/tex]

[tex]y=13-7=6[/tex]

Number of Chicken Burritos purchased=7

Number of Cheesy Gordita Crunch purchased=6

Answer:

See Explanation

Step-by-step explanation:

See comment for correct presentation of the question

Given

[tex]Expression = 40\% * 75[/tex]

[tex]Priya = \frac{2}{5} * 75[/tex]

Required

Is Priya correct?

We start by simplifying the expression.

[tex]Expression = 40\% * 75[/tex]

Express 40% as fraction

[tex]Expression = \frac{40}{100} * 75[/tex]

Simplify fraction: Divide numerator and denominator by 20

[tex]Expression = \frac{40/20}{100/20} * 75[/tex]

[tex]Expression = \frac{2}{5} * 75[/tex]

By comparing:

[tex]Expression = \frac{2}{5} * 75[/tex]

and

[tex]Priya = \frac{2}{5} * 75[/tex]

We can conclude that Priya is correct because:

[tex]40\% = \frac{2}{5}[/tex]

Solve for X
1) 8(1 + 5x) + 5 = 13 + 5x

Answers

Answer:

X=0

Step-by-step explanation:

[tex]8(1 \times 5x) + 5 = 13 + 5x \\ 8 + 40x + 5 = 13 + 5x \\ 40x + 13 = 13 + 5x \\ 40x - 5x = 13 - 13 \\ 35x = 0 \\ x = 35 \times 0 \\ x = 0[/tex]

The solution to the equation is x = 0.

Here, we have,

Let's solve the equation step by step:

Distribute the 8 to the terms inside the parentheses:

8 + 40x + 5 = 13 + 5x

Combine like terms on both sides of the equation:

40x + 13 = 5x + 13

Subtract 5x from both sides to isolate the variable terms on one side:

40x - 5x + 13 = 5x - 5x + 13

Simplifying:

35x + 13 = 13

Subtract 13 from both sides to isolate the variable term:

35x + 13 - 13 = 13 - 13

Simplifying:

35x = 0

Divide both sides of the equation by 35 to solve for x:

35x/35 = 0/35

Simplifying:

x = 0

Therefore, the solution to the equation is x = 0.

A forest covers 52000 acres. A survey finds that 0.4​% of the forest is​ old-growth trees. How many acres of​ old-growth trees are​ there?

Answers

Given:

Total forest area = 52000 acres

Area of old growth trees in the forest = 0.4%

To find:

The area of old growth trees.

Solution:

We have,

Total forest area = 52000 acres

Area of old growth trees in the forest = 0.4%

Area of old growth trees is

[tex]Area=0.4\% \text{ of total forest area}[/tex]

[tex]Area=\dfrac{0.4}{100}\times 52000[/tex]

[tex]Area=0.4\times 520[/tex]

[tex]Area=208[/tex]

Therefore, the area of old growth trees is 208 acres.
