2: 268,335
Step-by-step explanation:
hope it helps you
The expressions are evaluated using distributive property below -
We have -
i. 425 x 136
ii. 4005 x 67
We have to evaluate them with help of distributive property.
State the property of distributivity of multiplication over addition.Distributive property of multiplication over addition :
a × (b + c) = a × b + a × c
According to question, we have -
i. 425 x 136
ii. 4005 x 67
Now -
425 x 136 = 425 x (6 + 30 + 100) = 425 x 6 + 425 x 30 x 425 x 100
and
4005 x 67 = 4005 x (60 + 7) = 4005 x 60 + 4005 x 7
Hence, the evaluation using distributive property is done.

20. In the figure, O is the centre of the concentric circles of radii 17 cm
and 10 cm respectively. Chord AD of the larger circle cuts the smaller
circle at B and C such that AB = 9 cm. Find
(a) the distance of AD from the centre,
Answer:
I confirm my answer : 8(cm)
Step-by-step explanation:
In the triangle OAB, BO²=AB²+AO²-2*AB*AO*cos( BAC)
cos (BAC)=9²+17²-10²/(2*9*17)=15/17
AC/AO=cos(BAC) ==> AC=17*15/17=15
OC²=AO²-AC²=17²-15²=64
OC=8 (cm)

Solve for x: 3x - 5 + 2x = 25 - 5x
Answer:
x=3
Step-by-step explanation:
Add 2x and 3x
5x-5=25-5x
move -5x to the other side by adding 5x on both sides:
10x-5=25
Add 5 on both sides:
10x=30
Divide 10 on both sides:
x=3
Hope this helps!
Answer:
Step-by-step explanation:
5x - 5 = 25 - 5x
10x - 5 = 25
10x = 30
x = 3
A roof repairer works out that he will need to work with a colleage charges $20 per hour. In the end, they took 6 hours to fix the roof.
a. Write an expression with parentheses to describe how much the homeowner ownes for labor.
b. Evaluate your expression to calculate the cost of the labor.
a) 20(x)=y
b) $120
Let x= number of hours
Let y= Cost of labor
20 will remain constant, what matters is how many hours are being worked. If it's $20 per hour then it's safe to assume 1 hour is 20 dollars worth of labor. Due to it being per hour you have to multiply the rate by however many hours worked to get your final cost.
Jasper Hall sells farm chemicals. He is paid a commission of 99% of his first $6,000 in sales during the month and 14% on all sales over $6,000. What is his commission in a month in which he has sales worth $16,120?
Amount of total commission is $1,956.8 (Approx.)
Given:
Percent of commission upto $6,000 sale = 9% (Misprint)
Percent of commission over $6,000 sale = 14%
Amount of total sales = $16,120
Find:
Amount of total commission
Computation:
Amount of commission upto $6,000 sale = 6000 × 9%
Amount of commission upto $6,000 sale = $540
Amount remain = 16120 - 6000
Amount of commission upto $6,000 sale = $10,120
Amount of commission over $6,000 sale = 10,1200 × 14%
Amount of commission over $6,000 sale = $1,416.8
Amount of total commission = Amount of commission upto $6,000 sale + Amount of commission over $6,000 sale
Amount of total commission = 540 + 1,416.8
Amount of total commission = 1956.8
Amount of total commission = $1,956.8 (Approx.)

angle 7=100 ,angle 8=80
Step-by-step explanation:
For angle 7:
By using definition of alternate interior angles:
angle 4=angle 6
Subtitute values of angles:
x+2y=3y+20
x+2y-3y=20
x-y=20.......(1)
Now by using definition of alternate opposite angles:
angle 4= angle 2
angle 2=x+2y
Angle 1 and angle 2 are the angles of straight line ,there sum will be 180.
2x+y+x+2y=180
3x+3y=180
x+y=60......(2)
Add (1) and (2):
x-y=20
x+y=60
_______
2x=80
x=40
subtitute x=40 in (2):
40+y=60
y=60-40
y=20
For angle 7:
By using definition of alternate exterior angle:
angle 1=angle 7
angle 7=2x+y
subtitute x and y:
angle 7=2(40)+20
=100
For angle 8:
By using definition of alternate opposite angle:
angle 8=angle 6
angle 8= 3y+20
angle 8=3(20)+20
=80

find the distance between the two points in simplest radical form
The distance between the two points (7, - 1) and (9, - 9) is,
d = √68
We have to given that,
To find the distance between the two points (7, - 1) and (9, - 9)
Since, The distance between two points (x₁ , y₁) and (x₂, y₂) is,
⇒ d = √ (x₂ - x₁)² + (y₂ - y₁)²
Hence, We get;
The distance between the two points (7, - 1) and (9, - 9) are,
d = √ (9 - 7)² + (- 9 + 1)²
d = √4 + 64
d = √68
Therefore, the distance between the two points (7, - 1) and (9, - 9) is,
d = √68

If some one could figure out the x and y are
The problem is
3x+4y=50
-2x=y
Answer:
x = -10
y = 20
Step-by-step explanation:
y = -2x
so
substituting the value in equation ii
3x + 4y = 50
or, 3x + 4(-2x) = 50
or, 3x + (-8x) = 50
or, 3x-8x = 50
or, -5x = 50
so, x = -10
so
y = -2x
or, y = -2*(-10)
so, y = 20

hey friend
what's your question
The hypotenuse of a right triangle is 6 cm and one side is 2 cm longer than the other side. Find the length of each side to one decimal place.
Answer:
The two legs of the right triangle are approximately 3.1 cm and 5.1 cm and the hypotenuse is 6 cm.
Step-by-step explanation:
Let x be one leg of the right triangle.
Since the other leg is two centimeters longer, it can be represented by the expression:
[tex]x + 2 \text{ cm}[/tex]
According to the Pythagorean Theorem, for a right triangle:
[tex]a^2 + b^2 = c^2[/tex]
Where c is the hypotenuse and a and b are the two legs.
The hypotenuse is given to be 6 cm and the two legs are x and (x + 2). Hence:
[tex](x)^2 + (x+2)^2 = 6^2[/tex]
Solve for x. Simplify:
[tex]x^2 + (x^2 + 4x + 4) = 36[/tex]
Simplify:
[tex]2x^2 + 4x + 4 = 36[/tex]
Subtract:
[tex]2x^2 + 4x - 32 =0[/tex]
Divide:
[tex]x^2 + 2x - 16 = 0[/tex]
The equation is not factorable, so we can consider using the quadratic formula:
[tex]\displaystyle x = \frac{-b\pm\sqrt{b^2 -4ac}}{2a}[/tex]
In this case, a = 1, b = 2, and c = -16. Substitute:
[tex]\displaystyle x= \frac{-(2)\pm\sqrt{(2)^2-4(1)(-16)}}{2(1)}[/tex]
And evaluate:
[tex]\displaystyle \begin{aligned}x &= \frac{-2\pm\sqrt{68}}{2} \\ \\ &= \frac{-2\pm\sqrt{4\cdot 17}}{2} \\ \\ &= \frac{-2\pm2\sqrt{17}}{2} \\ \\ &= -1 \pm \sqrt{17} \end{aligned}[/tex]
Hence, our two solutions are:
[tex]\displaystyle x = -1 + \sqrt{17} \approx 3.1\text{ or } x = -1 - \sqrt{17} \approx -5.1[/tex]
Lengths cannot be negative, so we can ignore the second solution.
Hence, the value of x or the first side length is about 3.1 centimeters.
Since the other side length is two centimeters longer, the other side is about 5.1 centimeters.
In conclusion, the two legs of the right triangle are approximately 3.1 cm and 5.1 cm and the hypotenuse is 6 cm.
