Answer:1.7

Step-by-step explanation:

First you want to multiply 2.97 by 106

2.97 x 106 = 314.82

Now you want to multiply 1.72 by 107

1.72 x 107 = 184.04

Now you want to divide them

314.82 / 184.04 = 1.71

Now you want to round it to the nearest tenth... if a number is 5 or above you round it up but if it is 4 or below your number stays the same

Since 1 is lower than 5 you keep your number the same

What number would ypu add to both sides of x^2+7x=4 to complete the square

Tcecarenko [31]

For a monic quadratic (factor of 1 on $x^2$ ) we always add half the coefficient on the linear ( $x$ ) term, so

$\left(\dfrac 7 2\right)^2 = \dfrac{49}{4}$

Answer: 49/4

$x^2 + 7x + \dfrac{49}{4} = 4 + \dfrac{49}{4}$

$(x + \frac 7 2)^2 = 4 + \frac{49}{4}$

Terry drove 310 miles in 5 hours at a constant speed. How long would it take him to drive 403 miles at the same speed?

NeX [460]

Well, first, find-out how fast he was going the first time, by dividing 310 by 5. This gives you 62 mph. Now, divide 403 miles by 62 miles per hour in order to find-out how long it would take him to drive 403 miles, if he is constantly doing 62 mph. Your final answer is six-and-a-half hours.

Given the same triangle from part C, if line segment AB measures 12 inches and line segment BC measures 5 inches what is the mea

exis [7]

Answer:

4.615 in

Step-by-step explanation:

Triangle ABC and ABD are similar because they have two corresponding congruent triangles that is right angle and ∠A. Triangle ABC and BCD are similar because they have two corresponding congruent triangles that is right angle and ∠C. Therefore Triangle ABC, ABD and BCD are similar. Since they are similar, then their sides are proportional in length.

In triangle ABC, using Pythagoras theorem:

AC² = AB² + BC²

AC² = 12² + 5²

AC² = 144 + 25 = 169

AC² = 169

AC = √169 = 13 in

Using similar triangle for ΔABC and ΔABD:

$\frac{AC}{AB}= \frac{BC}{BD} \\\\\frac{13}{12}=\frac{5}{BD}\\\\BD=\frac{12*5}{13}\\ BD=4.615\ in$
