{put the given value of j and k in the given equation.. and solve ....}
Answer:
0.45
Step-by-step explanation:
This question is asking you to find the value of the equation when j = -4 and when k = -0.7. To do this, we must substitute j with -4 and k with -0.7:
(-4 * -0.7 - 1) / -4
= (2.8 - 1) / 4
= (1.8) / 4
= 0.45

2 4/3 divided by 6 7/8
Answers
Answer:
16/33
Step-by-step explanation:
2 4/3 --> 10/3
6 7/8 --> 55/8
10/3 / 55/8
10/3 x 8/55
80/165 --> divide by 5
16/33
Answer:
[tex]\frac{16}{33}[/tex]
Step-by-step explanation:
When you're having trouble dividing, use the "keep, change, flip" method. First reduced the fractions:
2 4/3 --> 10/3
6 7/8 --> 55/8
The problem should not be: [tex]\frac{10}{3}[/tex] ÷ [tex]\frac{55}{8}[/tex]
For "keep, change, flip", keep [tex]\frac{10}{3}[/tex] as normal, change the division symbol into a multiplication symbol (it's opposite), and flip [tex]\frac{55}{8}[/tex] to make [tex]\frac{8}{55}[/tex]
The problem should now be: [tex]\frac{10}{3}[/tex] × [tex]\frac{8}{55}[/tex]
Now multiple to get: [tex]\frac{80}{165}[/tex]
And reduce to get: [tex]\frac{16}{33}[/tex]
Determine which lines are parallel and which lines are perpendicular

Line c: -x + 3y = 6

Answers
• Parallel lines have the same slope, but different y-intercepts, because they start at different locations and stay the same slope next to each other for infinity.
• Perpendicular Lines have a negative reciprocal slope of the original line’s slope.
Solving:
We want the lines to be in slope l-intercept form: y=mx+b to determine the slope and y-intercept.
Line a: 3x+y=7 —> 3x-3x+y=7-3x —> y=-3x+7
Line b: 6x+2y=-8 —> 6x-6x+2y=-8-6x —> 2y=-6x-8 —> 2y/2=-6/2x+8/2 —> y=-3x+4
Line c: -x+3y=6 —> -x+x+3y=x+6 —> 3y/3=x/3+6/3–> y=1x/3+2.
Line a and b have the same slope of -3x with different y-intercepts; therefore, they are PARALLEL.
Line c has a different slope than lines a and b, so it is not parallel. Let’s see if it’s perpendicular to lines a and c.
Perpendicular lines have a negative reciprocal slope from the original line. Here’s the formula: y=x/z+b ——> y=-z/x+b
Line a: y=-3x+y
Line b: y=-3x+4
Line c: y=1x/3+2.
Let’s plug line a into the formula to see if the result is the slope of line c:
y=x/3+2 ——> y=-3/x+2.
Therefore, lines a and b are PERPENDICULAR to line c.

5x+28=7x-4
5x+32=7x
32=2x
x=16
Hope This Helps!!!
Answer:
x = 16
Step-by-step explanation:
(7x - 4) and (5x + 28) are alternate exterior angles and are congruent, so
7x - 4 = 5x + 28 ( subtract 5x from both sides )
2x - 4 = 28 ( add 4 to both sides )
2x = 32 ( divide both sides by 2 )
x = 16
Solve the right triangle shown in the figure. Bc =3.2m angle b = 43.2 degrees angle c = 90 degrees
Answers
Answer:
the missing angle is 46.8
Step-by-step explanation:
since all the angles in a triangle add up to 180, you can do the sum of the numbers that we know and subtract by 180
43.2+90= 133.2
180-133.2=46.8
so the missing angle is 46.8
we cant solve the sides of the triangle correctly without at least two known sides, and we only have one.
i hope this helps :)
The sides of the right triangle are AB = 2.27 m, BC = 3.2 m, and AC = 3.62 m.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
We are given that Angle B = 43.2 degrees, Angle C = 90 degrees and Side BC = 3.2 m
First, we can use the fact that the sum of the angles in a triangle is 180 degrees to find angle A:
Angle A = 180 degrees - Angle B - Angle C
Angle A = 180 degrees - 43.2 degrees - 90 degrees
Angle A = 46.8 degrees
Next, we can use the sine ratio to find the length of side AB:
sin(A) = opposite / hypotenuse
sin(46.8 degrees) = AB / 3.2 m
AB = sin(46.8 degrees) x 3.2 m
AB = 2.27 m
Finally, we can use the Pythagorean theorem to find the length of side AC:
AC² = AB² + BC²
AC² = (2.27 m)² + (3.2 m)²
AC² = 13.15 m²
AC = sqrt(13.15) m
AC = 3.62 m
Therefore, the sides of the right triangle are AB = 2.27 m, BC = 3.2 m, and AC = 3.62 m.

Answer:
30 ducks8 pigsStep-by-step explanation:
Let p represent the number of pigs. Then the number of ducks is 38-p and the number of legs is ...
4p +2(38 -p) = 92
2p = 16 . . . . . . . . . . . . collect terms, subtract 76
p = 8 . . . . . . 8 pigs in the field
38-p = 30 . . . number of ducks in the field

A pole that is 2.6 m tall casts a shadow that is 1.38 m long. At the same time, a nearby building casts a shadow that is 50.75 m long. How tall is the building?
Answers
Answer:
The building is 95.6159m tall.
Step-by-step explanation:
Both the pole and the building should have the same ratio of height to shadow length so we can come up with the equation:
[tex]\frac{2.6}{1.38}[/tex] = [tex]\frac{x}{50.75}[/tex]
Then solve for x, it will correspond to the height of the building.
x = 50.75([tex]\frac{2.6}{1.38}[/tex])
x = 95.6159m

Answers
Answer:
Step-by-step explanation.
Yes, there is another description of the pattern that will give the same first three numbers but will lead to a different pattern.
How can the pattern be described differently?While the student's claim of each number being two times the previous number holds true for the first three numbers (1, 2, and 4), there could be an alternative pattern such as an arithmetic progression.
If we consider the pattern as an arithmetic sequence with a common difference of 1, the first three numbers will be 1, 2 and 4 but the subsequent numbers in the pattern would differ as the arithmetic sequence would continue as 1, 2, 3, 4, 5,.....

Bases are equal, so compare the powers,

Answer to question 1 is 190 small pumpkins and 160 large pumpkins.
Answer to question 4 is 7 bags.
Step-by-step explanation for question 1:
190 = Small pumpkins
160 = Large pumpkins
190+160 = 350
So If you do 190 x 2 = £380
and 160 x 5 = £800
and 800+ 380 = £1,180
So Sal sold 190 small pumpkins and 160 large pumpkins!
