A hot liquid is placed in a refrigerator to quickly cool down. The temperature of the liquid can be modeled with the exponential function T=a(b)^m where m is the number of minutes it has been cooling. Based on the graph below, which of the following is closest to the value b for this model?
1) b=0.65
2)b=0.84
3)b=1.28
4)b=2.17

Answer:

m1= 43

m2=17

m3=120

m4=m5=m6=60

m7=17

m8=120

m9=43

Step-by-step explanation:

"Given ABC is an isosceles triangle and DBE is an equilateral triangle. we have to find each missing measure.

In triangle ABC,

∠1=∠9    (∵isosceles triangle)

⇒ 4x+3=9x-47

⇒ 9x-4x=3+47 ⇒ 5x=50 ⇒ x=10

Hence, ∠9=∠1=(4x+3)°=4(10)+3=43°

Also, given ΔBDE is an equilateral triangle, and all angle of equilateral triangle are equal.

∴ ∠4+∠5+∠6=180°

⇒ ∠4+∠4+∠4=180° ⇒ 3∠4 = 180° ⇒ ∠4 = 60°

∴ ∠4=∠5=∠6=60°

By exterior angle property, ∠3=∠5+∠6=60°+60°=120°

                                            ∠8=∠5+∠4=60°+60°=120°

In ΔABD, ∠1+∠2+∠3=180°

            ⇒ 43°+120°+∠2=180°⇒ ∠2 = 17°

In ΔABD, ∠9+∠8+∠7=180°

            ⇒ 43°+120°+∠7=180°⇒ ∠7= 17°"

Step-by-step explanation:

Add 72 and 56 and divide it by the biggest number until the answer is whole

Answer: 8

Step-by-step explanation:

Solve this problem with GCF (Greatest Common Factor).

Factors of 56: 1, 2, 4, 7, 8, 14, 28 and 56.

Factors of 72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36 and 72.

So, the biggest among the numbers that are matching is 8.

Answer:

-7/3

Step-by-step explanation:

6d + 8 = 3d + 1 (subtract 3d from both sides)

3d + 8 = 1 (now subtract 8 from both sides)

3d = -7 (divide both sides by 3)

d = -7/3

Answer:

Step-by-step explanation:

6d+8=3d+1

3d+8=1

3d=-7

3.15m or 3 3/20m

She has a total of 12.6m of ribbbon.

She has to make 4 flowers and each has ribbon.

You take 12.6÷4

Answer:

she would use 3.15 meters on each flower because when you divide 12.6 meters by 4 it equals 3.15 meters.

2x + 3y = r

---Subtract 2x from both sides

3y = r - 2x

---Divide both sides by 3

y = (1/3)(r) - (2/3)(x)

Hope this helps!! :)

Answer:

We can tell that 4:1 and 12:3 are equivalent ratios because if you simplify 12:3 you will get 4:1. You can also multiply 3 to both sides of 4:1 and you will get 12:3. You can also do this with other numbers.

Hello NiX010101!

[tex] \huge \boxed{\mathfrak{Question} \downarrow}[/tex]

Solve : [tex]\frac{ 3x-2 }{ 4 } - \frac{ 2x+3 }{ 3 } = \frac{ 2 }{ 3 } -x\\[/tex]

[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]

[tex]\frac{ 3x-2 }{ 4 } - \frac{ 2x+3 }{ 3 } = \frac{ 2 }{ 3 } -x \\ [/tex]

Multiply both the sides by the LCM of 4, 3 which is 12. After some simplification you'll get it as ..

[tex]3\left(3x-2\right)-4\left(2x+3\right)=8-12x [/tex]

Now, use the distributive property to open the brackets.

[tex]3\left(3x-2\right)-4\left(2x+3\right)=8-12x \\ 9x - 6 - 8x - 12 = 8 - 12x[/tex]

Now, bring the like terms together & simplify it.

[tex]9x - 6 - 8x - 12 = 8 - 12x \\ 9x - 8x - 6 - 12 = 8 - 12x \\ x - 18 = 8 - 12x \\ x + 12x = 8 + 18 \\ 13x = 26 \\ x = \frac{26}{13} \\ \large \boxed{\boxed{ \bf x = 2}}[/tex]

We got the value of x as 2.
