Elan Coil [88]

Answer:

Step-by-step explanation:

The two thermometers developed by cindy Grade and Gabriel Fahrenheit are shown in the attached photo

Let x = a certain temperature reading on the Gabriel Fahrenheit's thermometer

Let y = a corresponding temperature reading on the cindy Grade's thermometer

Interpolating the temperatures, it becomes

(212 - 32)/(212 - x) = (150 - 0)/(150 - y)

(212 - 32)(150 - y) = 150(212 - x)

180(150 - y) = 31800 - 150x

2700 - 180y = 31800 - 150x

180y - 150x = 31800 - 27000

180y - 150x = 31800 - 27000

180y - 150x = 4800

The scales will agree at a common reading. This is achieved by making x to equal y. Therefore

180x - 150x = 4800

30x = 4800

x = 4800/30 = 160

At a reading of 160, both scales will agree

The equations : -3x+4y=-30− and 9x + 5 y = 39 intersect at the coordinate (h, k). What is the value of h?
Phantasy [73]

Answer:

h = 6

Step-by-step explanation:

Given the 2 equations

- 3x + 4y = - 30 → (1)

9x + 5y = 39 → (2)

We require the value of the x- coordinate at the point of intersection, thus require to eliminate the y- term from the equations

Multiply (1) by 5 and (2) by - 4

- 15x + 20y = - 150 → (3)

- 36x - 20y = - 156 → (4)

Add (3) and (4) term by term thus eliminating y

- 51x = - 306 ( divide both sides by - 51 )

x = h = 6

Angad was thinking of a number. Angad adds 11, then divides by 8 to get an answer of 5. What was the original number?
galben [10]

Answer:

29

Step-by-step explanation:

x+11÷8=5

5 × 8 = 40

40- 11 = 29

29 + 11 ÷ 8 =5

Find the 4th term if the sequend in which a1 = 2 and a n+1 = -4a n + 2
pshichka [43]
a_n_+_1=-4a_n_+_2

dividing both sides by -4, we get:

a_n_+_2=- \frac{a_n_+_1}{4}

this means, each term is its previous term divided by -4.

now we can construct the sequence as follows:

a_1=2

a_2=- \frac{a_1}{4}= - \frac{2}{4}= -\frac{1}{2}

a_3=- \frac{a_2}{4} =- \frac{ \frac{1}{2} }{4}=- \frac{1}{8}

a_4=- \frac{a_3}{4}=- \frac{ \frac{1}{8} }{4}=- \frac{1}{32}



Answer: the last term is -1/32
