Elba and Jorge each make an error in the first two steps of solving the equation. 1/2(3x+4)-8=68-6(4/3+8x) Determine the error each student made. Then, solve the equation.
Answer:
x = 4 / 3 or 1.333 (Approx)
Step-by-step explanation:
Equation:
1/2(3x+4)-8=68-6(4/3+8x)
3x/2 + 4/2 - 8 = 68 - 24/3 - 48x
3x/2 + 2 - 8 = 68 - 8 - 48x
3x/2 + 48x = 66
By taking LCM
3x + 96x = 132
99x = 132
x = 132 / 99
x = 44 / 33
x = 4 / 3 or 1.333 (Approx)

PLSSSSSS HELP
A watermelon was ejected from a catapult reaching a maximum height of 20 ft. The watermelon left the catapult when it was 4 ft off the ground and hit the ground 45 ft away from the catapult. Can the equation that models the path of the watermelon be written given the information in the problem? If so, find the equation. If not, state what other information is needed.
Answer:
Step-by-step explanation:
No, the equation cannot be written with the given information. The distance from the catapult when the watermelon reached the maximum height is needed. Since the watermelon did not start on the ground, it cannot be assumed that the maximum was reached half the distance to the landing point.

Two friends, Ann and Malia, are growing out their hair. They plan to cut it off at a certain point and donate it to a
charity that makes wigs for people with cancer. Ann's hair is already 23 centimeters long and grows at a
constant rate of 3 centimeters per month. Malia's hair is 27 centimeters and growing at a speed of 1 centimeter
per month. If the girls get their hair cut on a certain day, they will have exactly the same length to donate. How
long will their hair be? How long will that take?
Answer:
When they get their hair cut it will be 69 inches long. It would take 23 months for both.

21% of the students at a High are in Maths group, 15 % are in science group, and 6 % are in both. If a student is selected randomly , what is the probability that the student is in maths or science group?
Answer:
6%
Step-by-step explanation:
The probability of picking a maths student = 21% = 21/100
The probability of picking a science student = 15% = 15/100 = 3/20
The probability of picking in both = 6/100 = 3/50
The probability that the student is in maths or science = 21/100 - 15/100 = 6/100 = 6%.

A scale factor of 4 applied to the dimensions of the prism. What effect will this have on the volume?
Answer:
its not A just took the test
Step-by-step explanation:
The effect this scale factor has on the volume is that the volume will be 64 times larger. The correct option is B.
What is a Scale factor?Scaled figures are zoomed in or zoomed out (or just no zoom) versions of each other. They have scaled versions of each other, and by scale, we mean that each of their dimension(like height, width etc linear quantities) are constant multiple of their similar figure.
So, if a side of a figure is of length L units, and that of its similar figure is of M units, then:
L = k × M
where 'k' will be called a scale factor.
The linear things grow linearly like length, height etc.
The quantities which are squares or multiple linear things twice grow by the square of the scale factor. Thus, we need to multiply or divide by k².
to get each other corresponding quantities from their similar figures' quantities.
So the area of the first figure = k² × area of the second figure
Similarly, increasing product-derived quantities will need increased power of 'k' to get the corresponding quantity. Thus, for volume, it is k cubed. or
The volume of the first figure = k³ × volume of the second figure.
It is because we will need to multiply 3 linear quantities to get volume, which results in k getting multiplied 3 times, thus, cubed.
Since the volume is the product of three linear quantities.
Therefore, if the scale factor of 4 is applied to the given prism then the volume of the prism will grow by 4³. Thus, we can write,
The volume of the scaled prism = 4³ ×Volume of the original volume
The volume of the scaled prism = 64 ×Volume of the original volume
Hence, the effect this scale factor has on the volume is that the volume will be 64 times larger.

Answer:
The measures of angles A, B, and C are respectively 21°, 125°, and 34°
Step-by-step explanation:
Equations
We are given some conditions applying to the internal angles on a triangle ABC.
The measure of angle A is 13 less than the measure of angle C.
The measure of angle B is 11 less than 4 times the measure of angle C
Let x = measure of angle C
The first conditions states:
[tex]m\angle A = x-13[/tex]
The second conditions states:
[tex]m\angle B = 4x-11[/tex]
The sum of all angles must be 180°, thus:
[tex]x - 13 + 4x - 11 + x = 180[/tex]
Simplifying:
6x -24 = 180
Adding 24:
6x = 204
Dividing by 6:
x = 204/6
x = 34
[tex]m\angle C = x = 34^\circ[/tex]
[tex]m\angle B = 4x-11 = 4*34-11 = 125^\circ[/tex]
[tex]m\angle A = x - 13 = 34 - 13 = 21^\circ[/tex]
The measures of angles A, B, and C are respectively 21°, 125°, and 34°
