i need help please!!!!!!!
Answer:
28°
Step-by-step explanation:
Complementary angles sum to 90° , thus
∠ DEF + ∠ LMN = 90°, that is
62° + ∠ LMN = 90° ( subtract 62° from both sides )
∠ LMN = 28°

The ratio of the radii of two circles is 2:3. The diameter of the smaller circle is 15 mm. What is the length of the diameter of the larger circle? 10.00 mm 11.25 mm 22.50 mm 30.00 mm
Answer:
The diameter of the larger circle is 22.50 mm
Step-by-step explanation:
Given;
ratio of radii of two circles = 2:3
diameter of the smaller circle, d = 15 mm
let the diameter of the larger circle = D
The ratio of the radii of the two circles is given by;
[tex]\frac{2r}{2R}= \frac{d}{D}= \frac{2}{3}\\\\ D= \frac{3d}{2}\\\\ D = \frac{3*15}{2} \\\\D = 22.50 \ mm[/tex]
Therefore, the diameter of the larger circle is 22.50 mm
Answer:
The diameter of the larger circle is 22.50 mm
Step-by-step explanation:
Given;
ratio of radii of two circles = 2:3
diameter of the smaller circle, d = 15 mm
let the diameter of the larger circle = D
The ratio of the radii of the two circles is given by;
Therefore, the diameter of the larger circle is 22.50 mm

Henry and Irene working together can wash all the windows of their house in 1 h 40 min. Working alone, it takes Henry 2 1 2 h more than Irene to do the job. How long does it take each person working alone to wash all the windows?
Answer:
Step-by-step explanation:
Henry and Irene working together can wash all the windows of their house in 1 h 40 min. Working alone, it takes Henry 2 1 /2 h more than Irene to do the job. How long does it take each person working alone to wash all the windows?
Let us represent
The number of hours Irene takes to do the job alone =x
1/x=Irene's work rate
The number of hours Henry takes to do the job alone = x + 2.5
1/(x+2.5)=Henry's work rate
1 hr and 40 min
Converting the 40 minutes to hour
60 mins = 1 hour
40 mins = x
x = 40/60
x = 0.6666666667 hour
1 hour 40 minutes = 1.67hours
Irene and Henry working together to do the job
Their work rate working together
sum of individual work rates=work rate when working together
1/x+1/(x+2.5)=1/1.67
LCD:(x)(x+2.5)(1.67)
(x+2.5)(1.67)+(1.67)(x)=(x)(x+2.5)
1.67x+ 4.175 +1.67x=x^2+2.5x
x^2+ 2.5x - 3.38x - 4.175
x^2- 0.84x - 4.175
Using Almighty formula
x = 42 minutes
x + 2.5 +
0.42 + 2.5 = 2.92 hours

If y is directly proportional to x, and y = 56 when x = 6, what is
the value of x when y = 84?
A)6
B)9
C)13
D)15
Answer:
B) 9
Step-by-step explanation:
According to the statement, we have the following relationship:
[tex]y \propto x[/tex]
[tex]y = k\cdot x[/tex] (Eq. 1)
Where:
[tex]k[/tex] - Proportionality constant, dimensionless.
[tex]x[/tex] - Independent variable, dimensionless.
[tex]y[/tex] - Dependent variable, dimensionless.
Such constant is eliminated by constructing this relationship:
[tex]\frac{y_{2}}{y_{1}} = \frac{x_{2}}{x_{1}}[/tex]
[tex]x_{2} = \left(\frac{y_{2}}{y_{1}} \right)\cdot x_{1}[/tex] (Eq. 2)
If we know that [tex]y_{1} = 56[/tex], [tex]x_{1} = 6[/tex] and [tex]y_{2} = 84[/tex], then the value of [tex]x_{2}[/tex] is:
[tex]x_{2} = \left(\frac{84}{56} \right)\cdot (6)[/tex]
[tex]x_{2} = 9[/tex]
Hence, the correct answer is B.
Is the relationship linear?
If yes, what is the rate of
change?
Answer
Linear, [tex]\frac{4}{-3}[/tex] is the slope
Step-by-step explanation:
Its linear because the rate of change doesn't change throughout our points.
Lets use our coordinate points for the bottom and middle one, making 1 our rate of our graph.
The bottom one that's closest to the x-axis would be (8,2). Move 8, the x, to the right, and up 2, the y The middle one of the points would be (5,6). Move 5, the x, to the right, and up 6, the y.
We have our points, now we find the rate of change, also known as slope.
So the equation for slope is m = [tex]\frac{db}{ca}[/tex] and our points together is (8,2)(5,6). Line up the variables with our points. So for example, 8 would be A, 2 would be B, 5 would be C and so on.
Then we have [tex]\frac{6-2}{5-8}[/tex]. Solve it, and we get [tex]\frac{4}{-3}[/tex].

Every 8th person at a concert receives a free t-shirt. Every 10th person receives a free keychain. If there are 160 people who attended the concert how many people will receive both a t-shirt and a keychain?
Answer:
4 people will receive both a t-shirt and a keychain.
Step-by-step explanation:
To determine how many people will receive both a t-shirt and a keychain,
First we will determine those that will receive a t-shirt and as well determine those that will receive a keychain.
For those that will a receive a t-shirt
Since every 8th person receives a t-shirt, then
The 8th, 16th, 24th, 32nd, 40th, 48th, 56th, 64th, 72nd, 80th, 88th, 96th, 104th, 112th. 120th, 128th, 136th, 144th, 152nd, and 160th persons will receive a t-shirt.
For those that will receive a keychain
Since every 10th person receives a keychain, then
The 10th, 20th, 30th, 40th, 50th, 60th, 70th, 80th, 90th, 100th, 110th, 120th, 130th, 140th, 150th, and 160th persons will receive a keychain.
From above, those that will receive both a t-shirt and a keychain are the 40th, 80th, 120th, and 160th persons.
Hence, 4 people will receive both a t-shirt and a keychain.
absolute value of -7 -5
Answer: for -7 is 7 for -5 is 5
Step-by-step explanation: the absolute value of a number is its distance from zero on the number line. For example, -7 is 7 units away from zero, so its absolute value would be 7.
Sometimes referred to as a numerical value, the absolute value is the non-negative value of a real number without regard for its sign. For example, the absolute value of both 12 and -12 is 12.
The absolute value of -5: |−5| is the absolute value of a negative number. To find the answer to this, you simply remove the negative sign, so the answer is 5

solve the system by Substitution 4x+4y=-4 y=-7x-7
Answer: {-1, 0}
Explanation: Since y = -7x - 7, we can replace the y in our first equation with
a -7x - 7 and our first equation now reads 4x + 4(-7x - 7) = -4.
To solve this equation, first distribute the 4 through the parenthses.
So we have 4x - 28x - 28 = -4.
Now simplify the left side to get -24x - 28 = -4.
Adding 28 to both sides, we have -24x = 24.
Dividing both sides by -24, we find that x = -1.
To find y, plug a -1 back into either equation.
So we have y = -7(-1) - 7 or y = 0.
Our final answer is {-1, 0}.
Answer:
x= -1,
y=0
