180°-(90°+68°)=180°-158°=22°
6
180°-22°=158°
Answer:
22° and 158°
Step-by-step explanation:
the sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 angles in the triangle from 180
∠5 = 180° - (90 + 68)° = 180° - 158° = 22°
∠5 and ∠ 6 form a straight angle, thus the angles are supplementary
∠6 = 180° - ∠5 = 180° - 22° = 158°

Answers
The graph of the linear equation y = 6x + 4 is drawn below.
The linear equation is given as,
x/a + y/b = 1
Where 'a' is the x-intercept of the line and ‘b’ is the y-intercept of the line.
The equation is given below:
y = 6x + 4
Convert the equation into intercept form, then we have
y = 6x + 4

-46 times a number minus 19 is equal to 86 less the number
Answers
Answer:
-46 * x - 19 = -86
Step-by-step explanation:
this a word problem!
lets break it down
-46 times a number
this will be -46 * x
minus 19 is equal to 86 less the number
-46 * x - 19 = -86
To solve the equation "-46 times a number minus 19 is equal to 86 less the number", we can simplify the equation by combining like terms and isolating x. The solution is x = -105/45 or approximately -2.33.
Explanation:To solve the equation -46 times a number minus 19 is equal to 86 less the number, we can first simplify the equation. Let's call the number x. So, -46x - 19 = 86 - x. We can solve for x by combining like terms and isolating x on one side of the equation. Adding x to both sides gives -45x - 19 = 86. Then, adding 19 to both sides gives -45x = 105. Finally, dividing both sides by -45 gives x = -105/45, which simplifies to x = -7/3 or approximately -2.33.

Answers
Answer:
Darin drove '2m - 20' miles.
Step-by-step explanation:
We are given that Sam drove 'm' no. of miles.
As, it is also given that Kara drove twice as many miles as Sam. Therefore we get that Kara drove '2m' no. of miles.
Now, it is given that Darin drove 20 miles fewer than Kara .i.e. Darin drove '2m - 20' no. of miles.
Hence, in terms of m, Darin drove '2m - 20' miles.

Your parents are renting an apartment for you when you go away to college. An annual contract is $502.00/month with a 2-month penalty if you break the lease. The month-to-month contract is $615.00/month. How much is the difference in payments if you stay the whole year?
Answers
Answer:
The month-to-month contract will cost an extra $1356.
Step-by-step explanation:
"An annual contract is $502.00/month with a 2-month penalty if you break the lease."
If you stay the whole year, and you pay $502 per month, you pay 12 * $502 = $6024 for the entire year.
"The month-to-month contract is $615.00/month."
If you stay the entire year, you pay 12 * $615 = $7380.
The difference is $7380 - $6024 = $1356
Elise took out a payday loan for $500 due in 2 weeks that charges an $80 fee. What is the periodic interest rate of the loan?
Answers
The periodic interest rate of Elise's payday loan is calculated by dividing the $80 fee by the $500 borrowed, resulting in a rate of 16% for the 2-week period.
To calculate the periodic interest rate of Elise's payday loan, we need to consider the fee charged as the interest for the period of the loan, since the loan is due in 2 weeks, which is a half-month period. Elise is being charged an $80 fee on a $500 loan, and this fee represents the interest for the loan's term.
Therefore, we can calculate the periodic interest rate by dividing the interest by the principal and the number of periods.
Here's the calculation:
Interest (Fee) = $80
Principal (Amount borrowed) = $500
Periodic interest rate = Interest / Principal
Periodic interest rate = $80 / $500 = 0.16 or 16%
Since the period is 2 weeks, we could express this interest rate on a monthly basis if needed by scaling the bi-weekly rate to a monthly rate. However, the loan terms only mention a 2-week period, so the periodic interest rate for the loan's duration is 16%.

Step-by-step explanation:
A rectangle has an area (x2-17x+72) square units.Since the area of a rectangle is determined using the formula, A= lw, what could be the length and width of the rectangle
Answers
okay first factor the binomial using binomial theorem. you probably don't remember that (at least I didn't) so here it is.
[tex] {x}^{2} - 17x + 72[/tex]
you have to figure out what two numbers add to -17 and multiply together to make 72
so make a table of all the numbers that add to 17 then multiply them together and see of they make 72. since it's -17 we will need to use two negative numbers:
-1 * -16 = 16
-2 * -15 = 30
-3 * -14 = 42? idk
-4 * -13 = something, math is hard
keep going until...
-8 * -9 = 72
so it's -8 and -9 are the factors we want.
we wrote this as:
[tex](x - 8)(x - 9)[/tex]
seeing this equal as our area in the a=l*w formula gives:
[tex](x - 8)(x - 9) = l \times w[/tex]
Now, plug in a number greater than 9.
It has to be greater than 9 because anything less than that would give us a negative area. Let's use 10 because it's easy. It doesn't matter which number you use as long as it's greater than 10. The problem appears to say it just wants a possible length and width, not a specific answer.
[tex](10 - 8)(10 - 9) = lw[/tex]
[tex]2 = lw[/tex]
so factors of 2.
length could be 1 and width could be 2 or vice versa.
you could also choose a different number than 10. let's try 20.
[tex](14 - 8)(14 - 9) = lw[/tex]
[tex](6)(5) = lw[/tex]
[tex]30 = lw[/tex]
so lw could also be 10 and 3 in this case. or 5 and 6. or 1 and 30. all these answers would be correct.
Answer:
length: 9
width: 8
Step-by-step explanation:
you would need to factorise the equation in order to work out the length and width of the rectangle
so to factorise x^2 -17x +72, you will need to numbers that multiply to make 72 and add to make -17
the numbers are -9 and -8
so the factorised equation is (x-9)(x-8)
if you equate it to 0 you get 9 and 8 as values for x
since the length is longer than the width
the length is 9 and the width is 8

The question involves solving algebra and geometry problems related to parallelograms, focusing on transformations, coordinates, and area calculations to find the equation for y.
Explanation:The student is asked to solve a series of algebra and geometry problems related to the properties of a parallelogram. These include finding coordinates, proving algebraic expressions, computing distances, and determining areas. The goal is to find the equation for y given a series of transformations and conditions on a square that becomes a parallelogram. Important concepts include the area of a parallelogram, vector addition using the parallelogram rule, and the determinant relating to a change of basis in vectors.
For example, part (e) involves finding the area of the parallelogram by computing twice the area of triangle PQO, using PQ as the base of the triangle. Solving for y in part (f) by setting this area equal to 1 involves understanding the effects of transformation on geometrical shapes and employing algebra to arrive at the desired equation.

How many centimeters are in 7 feet, given that 1 inch = 2.5 centimeters?
Answers
Answer:

Step-by-step explanation:
We need to convert 7 ft to cm
We know that 1 ft = 12 inches
7 ft * 12 inches/1 ft = 84 inches
We know that 1 inch = 2.5 cm
( 1 inch is really 2.54 cm but you question says 2.5 cm)
84 inches * 2.5 cm/1 inch = 210 cm
1. 1 in= 2.5 cm
x12 x12
___________
12 in/1ft= 30 cm
*12 inch = 1 foot
2. 1 ft= 30 cm
x7 x7
__________
7ft = 210 cm
1. We know that 1 in = 2.5 cm, so first change 1 inch to 12 in/ 1 foot by multiplying both sides of the equation by 12 to get 12 in/ft= 30 cm
2. Once we have our answer for 1 ft, multiply both sides again by 7 to get 7ft= 210 cm
