Answer:

d=0.031746

Step-by-step explanation:

1. Add 4d to both sides: 3.2=2.3d+3+4d

2. Simplify 2.3d +3+ 4d to 6.3d+3: 3.2=6.3d+3

3. Subtract 3 from both sides: 3.2-3=6.3d

4. Simplify 3.2-3 to 0.2: 0.2-6.3d

5. Divide both sides by 6.3: 0.2/6.3=d

6. Simplify 0.2/6.3 to 0.031746: 0.031746=d

7. Switch sides: d=0.031746

Hope this helped!

HELP DUE IN 10 MINS!

Scilla [17]

Answer:

$\checkmark \text{B. The area of the circle is } 729\pi,\\\checkmark \text{D. The arc length of the sector is } 12\pi$

Step-by-step explanation:

Area of a circle with radius $r$ : $r^2\pi$

Circumference of a sector with radius $r$ : $2r\pi$

Area of sector with angle $\theta$ : $r^2\pi\cdot \frac{\theta}{360}$ .

Arc length of sector with angle $\theta$ : $2r\pi\cdot \frac{\theta}{360}$

Using these equations, we get the following information:

Area of circle: $27^2\pi=729\pi$

Circumference of a circle: $2\cdot 27\cdot \pi=54\pi$

Area of sector: $27^2\pi\cdot \frac{80}{360}=162\pi$

Arc length of sector: $2\cdot 27\cdot \pi \cdot \frac{80}{360}=12\pi$

1. 1*1/6=___

Ratling [72]

Step-by-step explanation:

1. 1*1/6= 1 /6=1.67

2. 9*7/10= 63/10= 6.3

3. 7*4/8= 28/8= 3.5

4. 1/2 of 2= 1/2*2= 0.5*2= 1

5. 1/12 of 2= 1/12*2= 8.33*2= 16.66

6.2/6 of 2= 2/6*2= 3.33*2= 6.66

7. 1/3 of 5= 1/3*5= 3.33*5= 16.65

8. 3/10 of 8= 3/10*8= 0.3*8= 2.4

Hope it's help you ♥️

2(t+1)=10. need the answer for t I got the rest just can't get t

harkovskaia [24]

Answer: $t=4$

Simplify both sides of the equation

$(2)(t)+(2)(1)=10(Distribute)\\2t+2=10$

Subtract 2 from both sides

$2t+2-2=10-2\\2t=8$

Divide both sides by 2

$\frac{2t}{2} =\frac{8}{2} \\t=4$
