Solve for x, y and z ( help ♡ )

Explanation:

The rule used is [tex]\left(\frac{a}{b}\right)^{-c} = \left(\frac{b}{a}\right)^{c}[/tex]

That rule says to go from a negative exponent to a positive exponent, we apply the reciprocal of the fraction.

So,

[tex]\left(\frac{1}{3}\right)^{-5} = \left(\frac{3}{1}\right)^{5} = 3^5[/tex]

Answer:

HGD: 117

FDG: 180

Step-by-step explanation:

Answer:

<HDG = 117 degrees

<FDG = 63 degrees

Step-by-step explanation:

Its a straight line

These are supplementary angles

If its a striaght line its 180 degrees.

We already know theres a 63 degrees so we jsut gotta subtract

180-63=117

So 117 degrees for HDG

Part (i)

I'll use H in place of T to represent the heat of the object. That way there isn't a clash of variables lowercase t vs uppercase T.

The equation we're working with is updated to:

H(t) = 22 + a*2^(bt)

Plugging in t = 0 as the initial time value should lead to the temperature being H = 86 degrees Celsius.

So,

H(t) = 22 + a*2^(bt)

86 = 22 + a*2^(b*0)

86 = 22 + a*2^0

86 = 22 + a*1

86 = 22 + a

a+22 = 86

a = 86-22

a = 64

=====================================================

Part (ii)

We'll use the value of 'a' we found earlier. Plus we'll use the fact that H = 28 when t = 0.5 (since 30 min = 30/60 = 0.5 hr).

H(t) = 22 + a*2^(bt)

28 = 22 + 64*2^(b*0.5)

28-22 = 64*2^(0.5b)

64*2^(0.5b) = 6

2^6*2^(0.5b) = 6

2^(6+0.5b) = 6

log(  2^(6+0.5b)   ) = log(6)

(6+0.5b)*log(2) = log(6)

6+0.5b = log(6)/log(2)

6+0.5b = 2.5849625

0.5b = 2.5849625-6

0.5b = -3.4150375

b = -3.4150375/(0.5)

b = -6.830075

Answer:

(7+x)°=180-130

x=50-7

x=43

Answer:

264

Step-by-step explanation:

to find one hour

110÷5=22 per hour

12×22=264

Answer: Lamar would make $264 in 12 hours of work.

First we would try to find how much he would make in an hour, so technically the unit rate.

TO find the unit rate we have to do 110/5 which is equal to $22

Then we know that Lamar is working for 12 hours and that he makes $22 per hour. SO,  12 times 22 is 264.

Answer:

100,000

Step-by-step explanation:

[tex] (\dfrac{10^{-2}}{10^3})^{-1} = [/tex]

When you divide powers with the same base, subtract the exponents.

[tex] = (10^{-2 - 3})^{-1} [/tex]

[tex] = (10^{-5})^{-1} [/tex]

To raise a power to a power, multiply the exponents.

[tex] = 10^{-5 \times (-1)} [/tex]

[tex] = 10^5 [/tex]

[tex] = 100,000 [/tex]

Answer:

[tex]7.15*10^{-4}[/tex]

Step-by-step explanation:

[tex](8.1*10^{-4})-(9.5*10^{-5})=0.00081-0.000095\\\\=0.000715 = 7.15*10^{-4}[/tex]

Answer:

a) 2300 ml = 2.3 l

b) 9400 ml = 9.4 l

c) 9 l = 9000 ml

d) 7 l = 7000 ml

e) 9.7 l = 9700 ml

f) 670 ml = 0.67 l

g) 217 ml = 0.217 l

h) 1200 ml = 1.2 l

Step-by-step explanation:

For converting milliliter to liter, divide the number (ml) by 1000. For converting liter to milliliter multiply the number (l) by 1000.

Step-by-step explanation:

have a nice day :)

Answer:

6=7y-8

6+8=7y-8+8(addition inverse operation)

14=7y

14/7=7y/7(division inverse operation)

2=y

Step-by-step explanation:

Answer:

y=2

Step-by-step explanation:

6=7y-8

(to get all the numbers on the right side and the letters on left side we can swap 6 with 7y)

-7y= -6-8

(since both were positive before we used the inverse method to turn both into a negative number)

-7y= -14

÷7 ÷7

(to get y on its own we divide both sides by 7)

y=2

Hope this helped you- have a good day bro cya)

Answer:

[tex]5\frac{5}{6}[/tex]

Step-by-step explanation:

[tex]3\frac{1}{3}*1\frac{3}{4}[/tex]

[tex]\frac{10}{3} *\frac{7}{4} \\[/tex]

[tex]\frac{10*7}{3*4}[/tex]

[tex]\frac{70}{12}[/tex]

First you can divide both sides by 2

[tex]\frac{70}{12}=\frac{35}{6}[/tex]

Now make it as a mix number

[tex]\frac{35}{6} =5\frac{5}{6}[/tex]

Hope this helps you.
