Answer:
x =62
Step-by-step explanation:
The two angles form a straight line so they add to 180
x+118 = 180
Subtract 118 from each side
x = 180-118
x =62
Answer:
x = 62°
Step-by-step explanation:
These both angles are located at straight line.
So, the sum of both angles is 180 °.
x + 118 ° = 180 °
Subtract 118 ° from 180 °
x = 180 ° - 118 °
x = 62 °
Which quotient is greater than 3? 28 divided by 10, 35 divided by 11, 38 divided by 13 or 40 divided by 14
The quotient 35 divided by 11 is the only one among the options that is greater than 3.
To determine which quotient is greater than 3, we can calculate the value of each quotient:
28 divided by 10 = 2.8
35 divided by 11 ≈ 3.182
38 divided by 13 ≈ 2.923
40 divided by 14 ≈ 2.857
Comparing these values, we can see that only the quotient 35 divided by 11, which is approximately 3.182, is greater than 3.
Therefore, the quotient 35 divided by 11 is the only one among the options that is greater than 3.

Answer:
Ascending order
Step-by-step explanation:
Ascending numbers are numbers that begin from smallest to biggest.
solve for x
4^5x=(1/32)^1-x
x = -1
Step-by-step explanation:
[tex] {4}^{5x} = {2}^{2(5x)} = {2}^{10x} [/tex]
[tex] {( \frac{1}{32}) }^{(1 - x)} = {2}^{ - 5(1 - x)} = {2}^{(5x - 5)} [/tex]
or
[tex] {2}^{10x} = {2}^{(5x - 5)} [/tex]
Since both sides have the same base, we can write
10x = 5x - 5
or
5x = -5
x = -1
10/d(d-2) + 4/d = 5/d-2
Answer:
impossible
Step-by-step explanation:
a denominator can’t be equal to 0. So:
d ≠ 0 ; d ≠ 2
(10 + 4d - 8)/d(d-2) = 5d/ d(d-2)
4d + 2 = 5d
d = 2
But we have said that d can’t be equal to 2, so the equation is impossible.
Why is it easy to hammer a sharp pin than a blunt pin ? *
Answer:
It is easier to hammer a sharp nail than a blunt one
Step-by-step explanation:
This is because blunt nail occupies more area than sharped nail. As sharp will exert more pressure as it occupies less area.

Answer:
a + b = 7
Step-by-step explanation:
a^2 - b^2 = 21
Factor the left side. It is the difference of two squares which factors into the product of a sum and a difference.
(a + b)(a - b) = 21
We are told a - b = 3, so substitute 3 for the factor a - b.
(a + b)(3) = 21
Divide both sides by 3.
a + b = 7

11. Square ABCD shown has sides of length 10 centimeters. The unshaded
portions are both semicircles. Calculate the area of the shaded portion to
the nearest tenth of a square centimeter. *
Answer:
21cm^2
Step-by-step explanation:
Area of Square-Area of semi circles (makes one full circle)
Squares Area = 100
LxW or (10x10)=100
Circle Area = 25/pi
/pi (radius)^2 or /pi(5)^2 = 25/pi
100cm^2-25cm^2 = 21.4601…cm^2 rounded to 21.5 cm^2
The area of the shaded region is 21.5 cm²
What is a semi-circle?
'In geometry, a semicircle is a plane figure that is formed by dividing a circle into exactly two parts.'
According to the given problem,
Side length of the square = 10
Area of the square = ( 10 × 10 )
= 100 cm²
Now, for the semi-circle,
Diameter = 10 cm
Radius = [tex](\frac{10}{2}[/tex][tex])[/tex] cm
= 5 cm
Area of the semicircle = [tex]\frac{\pi r^{2} }{2}[/tex]
= [tex]\frac{\pi * 5^{2} }{2}[/tex]
Since, there are two semicircles in the square, we multiply the area with 2,
⇒ [tex]\frac{\pi *5^{2} }{2}*2[/tex]
= 25[tex]\pi[/tex]
Area of the shaded region = ( 100 - 25π )
= ( 100 - 78.53 )
= 21.46
≈ 21.5 cm²
Hence, we can conclude, the area of the shaded region is 21.5 cm².

SUPER URGENT: What is the range of y = sinx in the interval - π ≤ x ≤ 0?
-1 ≤ y ≤ 1
-1 ≤ y ≤ 0
0 ≤ y ≤ 1
y ≤ 1
Answer:
-1 ≤ y ≤ 0
Step-by-step explanation:
here, we simply want to know the range of values for sin x over the given interval
The range of values for sin x are simply the values in which y will take over the given interval of x
let’s start with the value sine (-pi)
We have this as;
0
And the value of sin (0) = 0
Recall, between -pi and 0, we have (-pi/2)
so sin (-pi/2) = -1
Thus, we have the correct range of values as;
-1 ≤ y ≤ 0

Help! What is the average rate of change of f(x)=x^2+3x+6 over the interval -3 less-than-or-equal-to x less-than-or-equal-to 3?
Answer:
The average rate of change of the function over the interval is 5.
Step-by-step explanation:
Average rate of change of a function:
The average rate of change of a function f(x) over an interval [a,b] is given by:
[tex]A = \frac{f(b)-f(a)}{b-a}[/tex]
Interval -3 less-than-or-equal-to x less-than-or-equal-to 3
This means that [tex]a = -3, b = 3[/tex]
[tex]f(x) = x^2 + 3x + 6[/tex]
So
[tex]f(b) = f(3) = (3)^2 + 3(3) + 6 = 9 + 9 + 6 = 24[/tex]
[tex]f(a) = f(-3) = (-3)^2 + 3(-3) + 6 = 9 - 9 + 6 = 6[/tex]
Average rate of change
[tex]A = \frac{f(b)-f(a)}{b-a} = \frac{24+6}{3-(-3)} = \frac{30}{6} = 5[/tex]
The average rate of change of the function over the interval is 5.
Find the sale price of an $18 item after a 50% discount.
Rewrite 50% as a decimal : 0.50
Multiply the price by 0.50:
18 x 0.50 = 9
The sale price is $9
Answer:
$9
Step-by-step explanation:

Select the two correct solutions of the inequality x + 8 > 14.
a. 2
b. 4
c. 6
d. 8
e. 10
PLEASE ANSWER QUICKLY !!
Answer:
d and e
Step-by-step explanation:
for a
substitute 2 for x
2 + 8 > 14
2 + 8 = 10
10 > 14
10 is not greater than 14 therefore 2 is not a solution to the inequality
for b
substitute 4 for x
4 + 8 > 14
4 + 8 = 12
12 > 14
12 is not greater than 14 therefore 4 is not a solution to the inequality
for c
substitute 6 for x
6 + 8 > 14
6 + 8 = 14
14 > 14
14 is not greater than 14 therefore 6 is not a solution to the inequality
for d
substitute 8 for x
8 + 8 > 14
8 + 8 = 16
16 > 14
16 is greater than 14 therefore 8 is a solution to the inequality
for e
substitute 10 for x
10 + 8 > 14
10 + 8 = 18
18 > 14
18 is greater than 14 therefore 10 is a solution to the inequality
we can conclude that the answers are d and e

Answer:
[tex](x-1)^2 + (y-1)^2 = 10[/tex]
Step-by-step explanation:
From the graph ,
Centre of the circle is (1, 1)
To find radius we find a point through which the circle passes and find the distance between the Centre and the point.
Let that point be (4, 0)
[tex]radius = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2} = \sqrt{(1-4)^2 + (1-0)^2} = \sqrt{10}[/tex]
Equation of the circle :
[tex](x - a)^2 + (y-b)^2 = r^2 \ , \ where \ (a,b)\ is\ the\ centre\ of\ the\ circle\ and\ r\ is\ the\ radius\\\\(x-1)^2 + (y-1)^2 = 10[/tex]

If j=h and k=m then which expression represents the value of g
Answer:
Step-by-step explanation:
as given j=h and k=m then which expression for g is
as from attached image , we can see that its look like two right angle triangle
so from lower triangle we apply the pythagorean theorem .
which state that sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse.
so small triangle ΔEBD
h² +k²= g² ---------------(1)
now from big triangle ΔABC
(j + h)² +(m + h)² =f²---------(2)
given j=h and k=m so from equation-2 we can find ,
(h + h)² +(k+ k)² =f²
(2h)² +(2k)²=f²
4h²+ 4k²= f²
4(h²+k²)= f² ----------(3)
now from equation 1 and 3 we can obtained .
4×g² =f²
take square root both side we get,
2×g=f
so g=f/2----- Answer

Answer:
$28.00
Step-by-step explanation:
1. The markup is 40% of the $20 cost, so the markup is:
(0.40)(20) = 8
2. Then the selling price, being the cost plus markup, is:
20 + 8 = 28
