Christine purchased a prepaid phone card for $25 . Long distance calls cost 21 cents a minute using this card. Christine used her card only once to make a long distance call. If the remaining credit on her card is $17.23 , how many minutes did her call last?

Answers

Answer 1

Answer : 37 minutes

Step-by-step explanation:

Subtract 25 and 17.23 then divide by 0.21

25-17.23=7.77 divide by 0.21 (21 divided by 100) =37

We can see two main triangles from the image which are;

ΔVWX and ΔYZX

The two triangles are similar and using ratio of similar triangles, we have;

VW/WX = YZ/ZX

Plugging in the relevant values gives;

10/6 = YZ/3

Cross multiply to get;

YZ = 3 * 10/6

YZ = 5 miles

Since speed is given as 3.2 miles per hour and we know that formula for time is;

time = distance * speed

Then; time = 5 * 3.2

time = 16 hours

What is the length segment of IL?

Answers

Answer:

IL = 11 cm

Step-by-step explanation:

Using the tangent ratio in right triangle IJL and exact value

tan45° = 1 , then

tan45° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{IL}{IJ}[/tex] = [tex]\frac{IL}{11}[/tex] = 1 , thus

IL = IJ =  11 cm

Answer:

11 cm

Step-by-step explanation:

Since m<IJL = 45 deg, and m<JIL = 90 deg, then m<ILJ is 45 deg.

That makes triangle IJL a 45-45-90 isosceles right triangle with congruent sides IJ and IL.

IL = IJ = 11 cm

Determine the value of x.

Answers

Answer:

25°

Step-by-step explanation:

The angle of a right triangle is always 90°. 90-35=51. 25 times 2 is 50 plus 1 is 51, so x is 25°.

The answer would be 25°

What is the equation of the line that passes through the point (-5, -2) and has a
slope of -6/5

Answers

Answer:

Step-by-step explanation:

you are given the slope m = -6/5 and one point (x1,y1) as (-5,-2)

next use  the point-slope formula [y-y1 = m(x-x1) ] and plug in the point and the slope

y-(-2) = -6/5(x-(-2))    ( they are making this tuff with all the minus signs :/ )

y+2 = -6/5(x+2)         ( nice looks better, distribute the -6/5 )

y + 2 = -6/5x -12/5    (move the 2 over )

y = -6/5x - 12/5 -2      ( 2 = 10/5 )

y = -6/5x -12/5 - 10/5    (add the fractions )

y = -6/5x -22/5    

that's in the form of the slope-intercept now  [ y = mx + b ] so you're done :)

ABC congruent DEF find the measure of the given angles or the lengths of the given sides​

Answers

Answer:

BC = 8 and EF = 8

Step-by-step explanation:

Congruent triangles have equal angles, equal sides, equal perimeters, and equal areas.

Let us solve the question

∵ The two triangles ABC and DEF are congruent

BC = EF

∵ BC = 3z + 2

∵ EF = z + 6

→ Equate their length

3z + 2 = z + 6

→ Subtract z from both sides

∵ 3z - z + 2 = z - z + 6

∴ 2z + 2 = 6

→ Subtract 2 from both sides

∵ 2z + 2 - 2 = 6 - 2

∴ 2z = 4

→ Divide both sides by 2

z = 2

→ Substitute z by 2 in the length of sides BC and EF to find them

∵ BC = 3(2) + 2 = 6 + 2

BC = 8

∵ EF = 2 + 6

EF = 8

When the positive integer m is divided by 6, the remainder is 5. What is the remainder when m+2 is divided by 6?

Answers

Answer:

The remainder is 1.

Step-by-step explanation:

First, you have to find the value of m. With the given information :

m ÷ 6 = 5

m = 5 × 6

m = 30 (no remainder)

if,

m = 30 + 5

m = 35 (with remainder as 5)

Next, you have to substitute m value into the expression, (m+2) ÷ 6 :

(35+2) ÷ 6

= 37 ÷ 6

= 6 1/6 (1 as a remainder)

The leadership class starts a campaign to change the school mascot. The school principal has agreed to change the mascot if two-thirds of the student body plus 1 additional student vote for the change. The required number of votes is 255. How many students attend the school? (Please also write the equation)

Answers

Answer:

254/2=127

127*3=381

381+1=382

Step-by-step explanation:

254/2 because 2/3 of the students is 254 and this is to simplify it

127*3 because 127 is 1/3 of the total number of students so 127*3 would be 3/3 of the students or all of them

381+1 because we had to take out 1 of the students because there was an aditional vote so we add him back in

Answers

9514 1404 393

Answer:

  D.  x^2 + 2x - 25

Step-by-step explanation:

The y-intercept is -25, eliminating choice C. The axis of symmetry is negative, eliminating choices A and B. (The axis of symmetry is x = -b/(2a), so the coefficient of x must be positive for a negative axis of symmetry.)

The only viable choice is D:

  x^2 + 2x - 25

_____

Additional comment

Though the y-intercept is in the right place, it seems to me the vertex and x-intercepts are slightly too far left for the given equation. That is why I chose to eliminate non-viable answers, rather than try to determine the equation directly. That is also why I elected to show a better graph of equation D.
