Answer:

Statements Justifications

E bisects AI, BC bisects AE, FH bisects EI Given

AE is congruent to EI Definition of Bisector

AD is congruent to DE Definition of Bisector

EG is congruent to GI Definition of Bisector

If AE is congruent to EI, AD is congruent to DE, and EG is congruent to GI, then AD is congruent to DE, EG, and GI, DE is congruent to AD, EG, and GI, EG is congruent to AD, DE, and GI, and GI is congruent to AD, DE, and EG. Therefore, AD is congruent to EG.

This isn't the best answer and probably won't get you a 100, but it shows effort so...

There is a beaker of 3.5% acid solution and a beaker of 6% acid solution in the science lab. Mr. Larson needs 200 milliliters of

oksian1 [2.3K]

Et x = the volume of the 3.5% solution
Let y = the volume 6% solution 

(3.5%)x + (6%)y = (4.5%)(200) 
0.035)x + 0.06y = 0.045(200) 
0.035x + 0.06y = 9 ( Equation 1 )

x + y = 200 ( Equation 2 )
x = 200 - y 

Substitute x = 200 - y into equation 1: 
0.035x + 0.06y = 9 
0.035(200 - y) + 0.06y = 9 
7 - 0.035y + 0.06y = 9 
0.06y - 0.035y = 9 - 7 
0.025y = 2 
y = 2/(0.025) 
y = 80 mL (the volume of 6% solution.)

Substitute y = 80 into equation 2: 
x + y = 200 
x + 80 = 200 
x = 200 - 80 
x = 120 mL (the volume of the 3.5% solution.)

Therefore, Mr. Larson should combine 120 mL of the 3.5% solution 
and 80 mL of the 6% solution to make 200 mL of 4.5% solution. 

Answer is 120 mL of the 3.5% solution & 80 mL of the 6% solution

Triangle ABC was dilated using the rule Do.4. Triangle

pshichka [43]

Answer:

The correct option is B. The length of OB' is 3 units.

Step-by-step explanation:

The rule of dilation is D₀,₄. It means dilation by scale factor 4 with center of dilation is origin.

$\text{Scale factor}=\frac{\text{Distance between center and any point of the image}}{\text{Distance between center and corresponding point of the Preimage}}$

$\text{Scale factor}=\frac{OB'}{OB}$

$4=\frac{OB'}{\frac{3}{4}}$

$4\times \frac{3}{4}=OB'$

$3=OB'$

The length of OB' is 3 units. Therefore the correct option is option is B.

A bicyclist rides 12 miles in 132 minutes. If she continues at this speed, how long will it take her to travel 66 miles? 24 minu

andrezito [222]

12 miles - 132 minutes
1 mile - 132/12 = 11 minutes
66 miles = 11 x 66 = 726 minutes.

Hence your requires answer is 726 minutes.
