How to find coordinates of a point using ratio

Answers

Answer 1

m1=3, m2= 1

point A= (-5,4)

point B=(7,-2)

x=m1x2+m2x1/ m1+m2 , y=m1y2+m2y1 / m1+m2

x= 3×7 +1×-5/3+1 , y= 3×-2+1×4 / 3+1

x= 21-5/4, y= -6+4/4

x= 16/4, y= -2/4

x= 4, y= 0.5

Alice found the area of the figure by breaking apart it apart where the dashed line is drawn. Her work is shown below. area of rectangle = bh = 6(2) = 12 mm2 area of triangle = bh = 2(2) = 4 mm2 area of figure = 12 + 4 = 16 mm2 A figure can be broken into a rectangle and triangle. The rectangle has a base of 6 millimeters and height of 2 millimeters. The triangle has a base of 2 millimeters an height of 2 millimeters. What error did Alice make? She didn’t use the correct formula for area of a triangle. She didn’t use the correct formula for area of a rectangle. She didn’t find the height of the triangle correctly.

Nic sells advertising packages for a radio station. The company pays him $150 per week and they also pay him $75 for every package he sells. His friend Asia works for the same radio station but she receives a salary only, which is $1,275 per week. How many packages does Nic need to sell in a week to earn as much as Asia?

Answers are:
A) 14
B) 15
C)16
D)20

Answers

I believe the answer would be 15, because Nic makes a base of $150 per week, so you would do the base $150+75=225 and keep going until you get 1275. The # of packages Nic would need to sell to reach Asia’s weekly pay is 15.

The height of a triangle is 6 m more than its base. The area of the triangle is 56 m². What is the length of the base?

Miss Laura by 12 pounds and 8 ounces of flour she used 4 ounces of flour in each batch of sugar cookies how many batches of sugar cookies did she make

Answers

Answer:

Step-by-step explanation:

so if 16 ounces are in each pound

lets multiply 12 x 16 = 192

now we have the pounds out add the leftover ounces

192 + 8 = 200

now that we can divide, but wait there is more to make its easier!

if 4 x 5 = 20

and 4 x 100 = 400

lets do 4 x 50 = 200

so now that 4 x 50 = 200

Miss Laura can make 50 batches of cookies.

find the area of the composite shape

Answers

Answer:

96 m²

Step-by-step explanation:

To calculate the area of a composite shape, you must divide the shape into rectangles, triangles, or other shapes.

A = l × w

L = length

W = width

Find the area and then add the areas back together.

12m × 8m

= 96 m²

The area of the composite shape is 96 m²

Answers

Answer:

60.22in^2.

Step-by-step explanation:

First, find the area of the rectangle. 14.1x7=98.7.

Then, we need to find the area of the circle and subtract it from the area of the rectangle.

The area of the circle is pi*r^2. so, pi*3.5^2 is about 38.48. (The radius is half of the diameter, so the radius would be 3.5).

Since there are two halves of the circle, we can just subtract 38.48 from 98.7 so get the area of the shaded region. So, the area of the yellow area is 60.22in^2.

Find rectangle area: 14.1 x 7 = 98.7

Find areas of semicircles: a = 3.14(3.5)^2 = 76.96

Subtract area of semicircles: 98.7 - 76.96 = 21.74

That would be -2n - 1.

Answer:

-2n - 1

Step-by-step explanation:

You have to combine like term which would be 4n,n,and 7n.

Since n doesn't have a variable just add a one in front. So now the equation would be

1n+4n-7n That equation equals -2n

Now just add the remaining number

So that makes the answer -2n -1

Step-by-step explanation:

Assuming we have the following

FD = 14

DE = 52

m<F = 90degrees

Required

m<D

DE = hypotenuse

FD = adjacent

Using the SOH CAH TOA identity

Cos m<D = adj/hyp

Cos m<D = 14/52

m<D = arccos(0.2692)

m<D = 74.38

m<D to the nearest degree is 74degrees
