Pleaseeeee Helpppp!!! What Is BC ? How Many Units

Answers

Answer 1

Answer:The answer is 25 units.

Step-by-step explanation:

here, ∡ABC=∡ACB

so, the given triangle is an isosceles triangle.

this means side  AB and side AC are equal

so, you can write 4x+4=6x-14

solving this equation, we get x=9

finally, BC=2x+7=2*9+7=25

a = 6x-11
g= 36
n = 7x - 27
Solve for x

Answers

Answer:

6x - 11 + 7x - 27 = 36

6x + 7x = 13x

-11 + (-27) = -38

13x - 38 = 36

-38 - 36 = -74

13x/13 = -74/13

x = -74/13

regularly $59.99, on sale for 40% off. What is the
totall paid, including 7.875% tax?


i just wanna know how to do the work:)

Answers

$59.99 divided by 40% would be $23.99 and if you deduct the said number by $59.99, this would make $36.

$36 + 7.875% tax (36 divided by 7.875 x 100) would be $38.39

Point M is located in Quadrant II of the coordinate plane. Point J has the same x-coordinate and the opposite y-coordinate as Point M. Point K has the opposite x-coordinate and the opposite y-coordinate as Point M Part A In what quadrant is Point J located Part B In what quadrant is Point K located?

Answers

Answer:

The answer is below

Step-by-step explanation:

The x-axis (horizontal axis) and y axis (vertical axis) divide the coordinate plane into four section known as quadrant.

In the first quadrant, the x and y coordinate are positive, in the second quadrant, the x coordinate is negative and y coordinate is positive. In the third quadrant, the x and y coordinate are negative while in the fourth quadrant, the x coordinate is positive and y coordinate is negative.

Point M is in Quadrant II, hence M = (-x, y).

Point J has the same x-coordinate and the opposite y-coordinate as Point M, hence J = (-x, -y).

Point K has the opposite x-coordinate and the opposite y-coordinate as Point M, hence K = (x, y).

A) Since J = (-x, -y), point J is in the third quadrant.

B) Since K = (x, y), point K is in the first quadrant

i am confused on how to solve this

Answer:

a) Both slopes are 4

b) The function g(x) has a greater y-intercept

Step-by-step explanation:

a) To find the slope of the function g(x), simply look at the coefficient (the number before the variable x). In this case, the coefficient is 4, so your slope is 4. This is because the equation is in slope-intercept form: y = mx + b where m is the slope.

To find the slope of function f(x), take two y-coordinates (y-coordinates are found in the column f(x)) and subtract one from another. This is your rise. Then, take two x-coordinates (from column x) and subtract one from another. This is your run. Divide the rise by the run, and you have your slope. In this case, you should get 4/1, or 4.

b) To find the y-intercept for function g(x), take a look at slope-intercept form again: y = mx + b, where b represents the y-intercept. So, the "b" of g(x) = 4x + 3 is 3. Your y-intercept is 3.

To find the y-intercept of function f(x), locate the row where there is a zero under column x. In this case, it's the second row. The number -1 is your y-coordinate when x is zero. Your y-intercept is -1.

-1 is less than 3, so the y-intercept of function g(x) is greater.

Hope this helps!

Alfredo is buying a watch for $200. He will make an initial payment of $50 and
then pay the remaining balance in payments of $15 per week.
Which function can be used to find a, the amount he will still need to pay at the
end of n weeks?

Answers

Answer:

Step-by-step explanation:

There is nothing to choose from.

However, 200-50 down payment will leave 150 left on the watch. 150 divided 15 a month is 10 months.

200=50+15(n)

200=50+15(10)

A company makes steel rods shaped like cylinders. Each rod has a radius of 2 centimeters and height of 70 centimeters. How much steel will the company need to make 243 rods? Use 3.14 for pie, and round your answer to one decimal

Answers

Answer:

213,645.6cm³

Step-by-step explanation:

Area of a cylinder is expressed as;

V = πr²h

r is the radius = 2cm

h is the height = 70cm

Get the volume of one rod;

V = πr²h

V = (3.14)(2)²(70)

V = (3.14)(4)(70)

V = 879.2cm³

one steel = 879.2cm³

243 rods = x

Cross multiply;

x = 879.2 * 243

x = 213,645.6

The company will need 213,645.6cm³ volume of steel to make 243 rods
