If y varies jointly as x and z and y=60 when x= 10 and z=-3, find y when x=8 and z=15.
Answer:
y = -240
Step-by-step explanation:
If y varies jointly as x and z, then y/(xz) = k where k is the constant of proportion
60/10(-3) = 60/-30 = -2 = k
Now, y/(xz) = -2
y/8(15) = -2
y/120 = -2
y = -240

hope it helps
Answer:
37°
She likely thought that angle b and 53° added up to 180 instead of 90
Step-by-step explanation:
b and 53° make a right angle
b + 53° = 90°
90° - 53° = 37°
She likely thought that angle b and 53° added up to 180 when it actually adds up to 90

Answer:
PT = 11
Step-by-step explanation:
In a parallelogram, the diagonals bisect each other. So, QS cuts PR in half so that PT = TR
PT + TR = PR = 22
2 * PT = 22
PT = 11
Answer:
PT = 11
Step-by-step explanation:
Theorem: The diagonals of a parallelogram bisect each other.
So, if PR = 22, then PT = 11
See how easy that is if you know the theorem.

The area of a rectangle is 192 in ^2. The ratio of the length to the width is 4:3. Find the length and the width.
The length of the rectangle is ___ in.
The width of the rectangle is___.
Answer:
Length = 16 in
Width = 12 in
Step-by-step explanation:
Given:
Area of a rectangle = 192 in²
Ratio(length to width) = 4:3
Find:
Length and the width
Computation:
Ratio(length to width) = 4:3
So,
Length = 4a
Width = 3a
Area of a rectangle = Length x Width
192 = 4a x 3a
192 = 12a²
a² = 16
a = 4
Length = 4a = 4 x 4 = 16 in
Width = 3a = 3 x 4 = 12 in
Trapezoid

If a triangle has a leg with a length of 6 units and a hypotenuse with a length of 10 units, find the length of the other leg.
Answer: 8 units
Step-by-step explanation:
This can be solved using the Pythagorean Theorem:
c² = a² + b²
c is the hypotenuse
a and b are the sides
Solving for the length:
10² = 6² + b²
100 = 36 + b²
b² = 100 - 36
b² = 64
b = √64
b = 8 units
The missing side is 8 units.

1. A landscaping company charges $100 for its services plus $15 per hour. Another company charges $40 per hour. Find the number of hours for which the two companies would charge the same amount.
2. Refer to the previous problem. What would that charge amount be?
Answer: 4 hours, $160
Step-by-step explanation:
100+15x= 40x
100= 25x
4=x
4 Hours
4*40 = 160
or 100 + 15*4= 160

Answer:
The first one does not work, the second one does.
Step-by-step explanation:
Use the triangle inequality formula:
a = 15
b = 37
c = 53
15 + 37 > 53 No
It does not work.
a = 9
b = 16
c = 8
9 + 16 > 8 Yes
9 + 8 > 16 Yes
16 + 8 > 9 Yes
The first one does not work, the second one does.
Hope this helps! <3
Determine a pair of angles (one positive and one negative) in degree measure coterminal to the angle 117°.
Answer:
Option B.
Step-by-step explanation:
When we have an angle A, in degrees, the coterminal angles are all the angles that can be written as:
B = A + n*360°
Where n is a positive or a negative integer (if n = 0, then B = A, which means that A is coterminal with itself, which is trivial).
Now we want to find two coterminal angles to 117°, such that one is positive and the other negative.
Then we can do:
for the positive one, use n = 1.
B = 117° + 1*360° = 477°
For the negative one, use n = -1
B = 117° - 1*360° = -243°
Then the two angles are 477° and -243°
The correct option is B.
A canister holds 3 blue pens, 4 black pens, 2 red pens, and 6 pencils. The simplified ratio of ALL the pens to pencils is
Answer:
The simplified ratio of ALL the pens to pencils is
= 3:2
Step-by-step explanation:
A canister holds 3 blue pens, 4 black pens, 2 red pens, and 6 pencils.
Step 1
Sum of all the pens is:
Blue pens + Black pens + Red pens
= 3 + 4 + 2
= 9 pens
Number of pencils = 6 pencils
Step 2
The simplified ratio of ALL the pens to pencils is
Pens : Pencils
= 9 : 6
= 3:2
Will a pair of 6 feet 11 inch long skis fit in a wardrobe that is 3 feet long, 2 feet wide and 6 feet high?
Answer:
Step-by-step explanation:
Length of a pair of skis = 6 feet 11 inches
Maximum length of a the skis that can be fitted in a wardrobe is along the diagonal of the wardrobe.
From the picture attached,
BC² = 3² + 2² [By Pythagoras theorem]
BC = √(13)
By applying Pythagoras theorem in ΔABC,
AB² = AC² + BC²
AB² = 6² + (√13)²
= 36 + 13
AB = √49
Ab = 7 feet
Since, "diagonal length of the wardrobe is more than the length of skis,
skis can be fitted"

Answer:
see below for a graphone possible solution: (12, 5)Step-by-step explanation:
I like a graphing calculator for creating graphs. Here, each inequality is in "slope-intercept" form, so the y-intercepts are easily located (+8 and -4).
The slope (x-coefficient) is the "rise" divided by the "run". The boundary line of the first inequality has a rise of -1 for each run of 3 to the right. The second rises 5 units for each 3 to the right. Starting from the y-intercept, additional points to plot are easily found.
Of course, the boundary line is solid for y ≥ ( ), and is dashed for y < ( ). The shading will be above the line (for higher y-values) for the first inequality, and below the line (for lower y-values) for the second inequality. That puts the double-shaded solution area in the right-side quadrant of the X where the lines cross.
There are an infinite number of solution points to choose from. One of them is (12, 5). Points with an x-value that is a multiple of 3 will be easiest to substitute into the inequalities to check.
5 ≥ (-1/3)(12) +8 ⇒ 5 ≥ 4 . . . true
5 < (5/3)(12) -4 ⇒ 5 < 16 . . . true

Chandra and her friends bought three tubs of popcorn at the movies for t dollars each and some candy that cost $7.00. If the girls spent less than $28, what is the most a tub of popcorn could cost? Write an inequality to represent the situation.
Answer:
3t+ 7 < 28
Step-by-step explanation:
The inequality function as follows;
Given that the cost is $7
There are three tubs of popcorn i.e. t
And, if the girl spend lower than $28 so the inequality function is
3t + 7<28
Hence, the above represent the answer

Element X decays radioactively with a half life of 8 minutes. If there are 480 grams of
Element X, how long, to the nearest tenth of a minute, would it take the element to
decay to 14 grams?
y=a(.5)
Answer:
40.8 minutes
Step-by-step explanation:
Element X decays radioactively with a half life of 8 minutes. If there are 480 grams of Element X, how long, to the nearest tenth of a minute, would it take the element to decay to 14 grams?
The formula to find how long it would take which is the time elapsed is given as:
t = t½ × In(Nt/No)/-In2
t = ?
t½ = 8 minutes
Nt = Amount after the time of decay = 14 grams
No = Original Amount of substances = 480 grams
t = 8 × In(14/480)/-In2
t = 40.796285388407 minutes
Approximately to the nearest tenth = 40.8 minutes
Therefore, it would take the element X, 40.8 minutes to decay to 14 grams

Answers:
C) x = plus/minus 11B) No real solutionsC) Two solutionsA) One solutionThe value 18 goes in the first blank. The value 17 goes in the second blank.========================================================
Explanations:
Note how (11)^2 = (11)*(11) = 121 and also (-11)^2 = (-11)*(-11) = 121. The two negatives multiply to a positive. So that's why the solution is x = plus/minus 11. The plus minus breaks down into the two equations x = 11 or x = -11.There are no real solutions here because the left hand side can never be negative, no matter what real number you pick for x. As mentioned in problem 1, squaring -11 leads to a positive number 121. The same idea applies here as well.The two solutions are x = 0 and x = -2. We set each factor equal to zero through the zero product property. Then we solve each equation for x. The x+2 = 0 leads to x = -2.We use the zero product property here as well. We have a repeated factor, so we're only solving one equation and that is x-3 = 0 which leads to x = 3. The only root is x = 3.Apply the FOIL rule on (x+1)(x+17) to end up with x^2+17x+1x+17 which simplifies fully to x^2+18x+17. The middle x coefficient is 18, while the constant term is 17.
