Answer:

2.4

Step-by-step explanation:

You have to divide 6.4 by 2.4 to get 2.66666666667.

Then you multiply 2.66666666667 and 0.9 to get 2.4

When x = 6.4, y = 2.4

Answer:

50 minutes

Step-by-step explanation:

Amount of time his journey took = 15km ÷ 18km/h

                                                      = 0.833h (to 3sf)

                                                      = 50 minutes

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:

V = 72 & W = 72

Step-by-step explanation:

All angles of a triangle will be equivalent to 180 degrees.

We start by subtracting first.

180 - 36 = 144

Look back at the triangle. FG and HG are congruent, which means the values of V and W will be the same.

The last step is to divide.

144 / 2 = 72

V = 72 & W = 72

Step-by-step explanation:

Greatest common factor (GCF) of 22 and 44 is 22.

GCF(22,44) = 22

We will now calculate the prime factors of 22 and 44, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 22 and 44.

Answer:

x° = 35°

Step-by-step explanation:

at 125° to get the opposite angle

180° - 125° = 55°

then,

x° + 90° + 55° = 180°

x° = 180° - 145°

x° = 35°

Answer:

You will need 32 ounces

Step-by-step explanation:

Answer:

-5 divide by 28

Step-by-step explanation:

so the question supposed be " 15-20 divided by 2(4) + 20

15-20 which is also 15 + (-20)= -5

2(4)=8, 8+20=28

so it can simplify into -5 / 28

Similar triangles may or may not be congruent.

The congruent criterion to use in her proof is (b) SAS theorem

From the question, we understand that she draws an angle bisector from [tex]\mathbf{\angle Q}[/tex] to side PR

This means that, either sides of angle Q are congruent. (this is represented by A i.e. angle)

When [tex]\mathbf{\angle Q}[/tex] is bisected, sides PB and RB become congruent

i.e. [tex]\mathbf{PB \cong RB}[/tex] ... (this is represented by S i.e. side)

Lastly, both triangles share a common side at QB .. (this is also represented by S i.e. side)

So, we have: SAS

Hence, the congruent criterion to use in her proof is (b) SAS theorem

Answer:

x = -2

Step-by-step explanation:

It's a matter of rearranging the equation to make x the subject. Simple arithmetic.

Original equation:

-1.2x + 2.5 = 0.8x + 6.5

Start moving constants with variables to left, and constants without variables to right:

-1.2x - 0.8x + 2.5 = 6.5

-1.2x - 0.8x = 6.5 - 2.5

Collect like terms

-2x = 6.5 - 2.5

-2x = 4

Divide both sides by -2 to make x the subject

x = 4/-2

x = -2

Answer: x = - 2.0

Step-by-step explanation:

We can find x by making it the subject of the equation and simplifying:

     −1.2x+2.5=0.8x+6.5      [group like terms across the equal sign]

      -1.2x - 0.8x = 6.5 - 2.5     [simplify]

              - 2.0x = 4                 [divide both sides by -2.0]

                     x = -2.0

Check:

 −1.2(-2.0)+2.5  =  0.8(-2.0)+6.5
