If you cut away a triangle of area 59cm^2,the remaining area will be 85cm^2.Find the length of the side of the square before it was cut.?

Answers

Answer 1
Answer: side length = 12

Explanation

let x be the original area

Thus x - 59 = 85

=> x = 85 + 59
x = 144

Since we know the original shape is a square and Area of a square = side x side.

Find side length:

A = a^2

But A = 144

144 = a^2
12 = a

So the side of the square b4 it was cut is 12 cm

Answers

Answer:

y = -4/3 x + 2

Step-by-step explanation:

Let us assume the equation given is 3y + 4x = 6

The standard form in slope-intercept form is y = mx+c

m is the slope

c is the intercept

Make y the subject of the formula

3y + 4x = 6

3y = -4x + 6

Divide through by 3

3y/3 = -4/3 x + 6/3

y = -4/3 x + 2

Hence the equation of the line in slope-intercept form is y = -4/3 x + 2

Answer:

CD = 4

Step-by-step explanation:

I believe you know the geometric mean for altitudes?

CD = √AD * DB = √8 * 2 = √16 = 4

If you are not aware of this theorem, then use the similarity of triangles.

ADC ~ CDB

AD/DC = CD/DB (cross-multiply)

CD^2 = AD*DB,

CD = √AD * DB = √8 * 2 = √16 = 4

Given the equation of line y = -2x : Does the point M( 1/2 , 1) belong to the graph?
PLEASE HELP ME! I promise to mark brainliest if you give me the correct answer. Thank you!!

Answers

Answer:

no it does not belong to the graph

Step-by-step explanation:

plug in the x-coordinate and see if it gives you the y-coordinate (1). if 1 is what comes out, then it is not a point on the graph.

y = -2(1/2)

y = -1

y = -1  when x = 1/2, which is not 1 so it does not belong to the graph

Find 3 numbers in G.P whose sum is 28 and whose product is 512

Answers

Answer:

4, 8 and 16

Step-by-step explanation:

a/r ×a×ar =512

a^3 =512

a = cube root of 512

a=8

8/r+8+8r=28

8r^2+8=20r

8r^2-20r+8=0

8r^2-16r-4r+8=0

8r(r-2)-4(r-2)=0

(8r-4)(r-2)=0

r=2

8r=4

so r=2 or r=1/2

so of r is 2

8/2=4

and 8×2=16

Hello, I need help. thank you

Answers

Answer:

B

Step-by-step explanation:

all you need to do is add 5 to the y for example ( -5, 5) add 5 to the (x,5) to make ( -5,10). As you can see only the y value is shifting, not the x value, that's why you need to add 5 to all the y values.

So the answer here is B.

Answer:

B

Step-by-step explanation:

The answer is B because 5 units up from 5 is 10. A and B both have a y coordinate of 5 and the answer letter B is the only one that mention 10 as a y coordinate twice

Númer total de ladrillos= 256

Step-by-step explanation:

Dada la siguiente información:

Total de pisos= 16

Total de ladrillos por piso= 16

Para calcular cantidad de ladrillos en total, tenemos que usar la siguiente formula:

Número total de ladrillos= total de ladrillos^2

Número total de ladrillos= 16^2

Númer total de ladrillos= 256

En este caso lo hace al cuadrado por que la cantidad de pisos y ladrillos por piso es la misma. Sino, es mejor expresarlo como una multiplicación.
