HIJK is a rectangle. HJ=x and IK=2x-7 Find the length of each diagonal

1 answer:

3 0

The diagonals of a rectangle are congruent so set them equal to each other to get x = 2x - 7. isolate the variable (0 = x - 7 — x = 7) to get x = 7. the diagonals are seven.

What is the approximate volume of a cylinder with a diameter of 10 meters and a height of 5 meters? Use 3.14 for pi. A. 392.5 m3

EastWind [94]

For cylinder
d=10m
So r=5m
h=5m
volume=pi×r^2×h
=3.14×5×5×5
=3.14×125
=392.5m^3
So option a is correct.

Identify the values of a,b, and c that could be used with the quadratic formula to solve the equation. Enter a as a positive int

Goshia [24]

Answer:

a=1

b= -6

c=48

Step-by-step explanation:

x^2=6(x-8)

x^2=6x-48

x^2-6x+48

a,b are the coefficients of x^2 and x

c is the constant value present

Therefore it is basically written as ax^2+bx+c

and comparing with the answer x^2-6x+48,

a=1, b= -6, c=48

Solve the compound inequality 6b < 36 or 2b + 12 > 6.

ss7ja [257]

Answer:

all values of b

Step-by-step explanation:

6b < 36 or 2b + 12 > 6.

First solve the one on the left

6b < 36

Divide by 6

6b/6 < 36/6

b <6

Then solve the one on the right

2b + 12 > 6

Subtract 12 from each side

2b+12-12 >6-12

2b >-6

Divide by 2

2b/2 >-6/2

b >-3

b<6 or b >-3

Rewriting

b>-3 or b<6

b > -3 is an open circle at -3 with a line going to the right

b < 6 is an open circle at 6 with a line going to the left

The or means we add the lines together

We have a line going from negative infinity to infinity

all values of b

The sum of two consecutive number is 15. the number are and solve

Fiesta28 [93]

By Question it's given that the sum of two numbers is 15 . And we need to find out the numbers. So ,

Let us take :-

First number = x
Second number = x + 1

According to the Question :-

$\sf\implies x + x +1=15\\\\\sf\implies 2x = 15-1\\\\\sf\implies 2x =14 \\\\\sf\implies x =14/2 \\\\\sf\implies\red{ x = 7 }$

Therefore :-

First number = 7
Second number = 8

Hence the two numbers are 7 and 8.
