Find ""k"" so that the 58 unit diagonal of a rectangle can have an aspect ratio of 15:8. Then find the length and width of the rectangle and find its area.
Step-by-step explanation:
The area of any 2-d quadrilateral is equal to the base of the shape times the height, though we can just sub in length and width here. The key bits of information here is the aspect ratio (4:3) and the given area (300 in^2).
So far this gives us L∗W=300in2
Now, the aspect ratio given implies for every 4 inches in length, there will be 3 inches in width. This allows us to factor out a 4 and a 3 from the Length and Width respectively and give them the same constant variable, like so:
4x∗3x=300in2
Now, some might be tempted to go ahead with 12x here, but let’s expand the left side out to see what’s really going on:
4∗x∗3∗x=300in2
From here, let’s resolve like terms Our constants will multiply together and give us 12, and x * x of course gives us x^2 to give us the following:
12x2=300in2
From here, simply divide through by 12 to isolate x on one side,x2=25
And finally take the square root of both sides to work out what your common factor is,
x=5
Now that we have out common factor, let’s plug it back into our original formula to find our Length and Width, like so.
(4∗5)in∗(3∗5)in=300in2
20in∗15in=300in2
Therefore, the Length of our rectangle is 20in, and the Width of our rectangle is 15in

Answer:
x=17 degrees
m1=97 degrees
Step-by-step explanation:
6x-19=3x+32(vertically opposite angles)
6x-19-3x=32
3x =32+19
3x=51
x=17 degrees
when we substitute x in these:
6x-19=83
3x+32=83
if 1=y
83+83+Y+Y=360(points around a point is 360 degrees)
166+2Y =360
2Y =360-166
2Y=194
Y=97
Therefore 1=97 degrees

A boy's age in ten year time will be four times his age five years ago. Find his present age.
Answer:
He is ten.
Step-by-step explanation:
10 yrs old. Go ahead 10 yrs to make 20. Which is four times as much as five years old. (Which is 5 years before 10)
Hope this helps! :)
Answer:
Present age = 10
Step-by-step explanation:
Let us assume that,
→ Present age = x
Forming the equation,
→ x + 10 = 4(x - 5)
Now the value of x will be,
→ x + 10 = 4(x - 5)
→ x + 10 = 4x - 20
→ x - 4x = -20 - 10
→ -3x = -30
→ x = -30/-3
→ x = 30/3
→ [ x = 10 ]
Hence, the boy's age is 10.

unit 2: equations and inequalities/ homework 11: compound inequalities
Answer:
The answer is in the image! The interval notation is [-5,4)
Step-by-step explanation:
Notice that on the linee graph it shows a open circle on 4 and a closed dot on -5... This is because the number can be greater than -5 or equal to(this is represented by the brackets) and on 4 it can only be less than 4 and not equal to it (Represented by parenthesis)...
To solve for the inequality you must solve for x. The easiest way to do this is to multiply each component in the middlee by 3, the add two on both sides, then divide by 9 on both sides. This gives you the simplest inequality at -5<= x <4!
Hope this helps! If you cant open the image let me know!

Which statement is true when describing the absolute value of the point represented on the number line?
A) The absolute value of 7 is −7 because the number is seven units to the right of zero on the number line
B) The absolute value of 7 is positive 7 because the distance from zero to 7 on the number line is seven units.
C) The absolute value of 7 is −7 because zero is seven units to the left of 7 on the number line...
D) The absolute value of 7 is −3 because the number is 3 units to the left of 10 on the number line.
What is the absolute value of −9 on the number line?
A) 9
B) −9
C) 0
D) 1
The absolute value of 7 is positive 7 because the distance from zero to 7 on the number line is seven units.
The absolute value of -9 on the number line will be 9 units from zero.
Explanation:
The absolute value of a real number is only the number irrespective of its sign. For example: The absolute value of '6 is '6' and the absolute value of '-8 ' is 8.The absolute value of a number can also be thought of as the distance from zero along the number line of a real number.Given :
1) Four statements describing absolute value.
2) The absolute value of -9 on a number line.
To find:
1) The true statement.
2) The absolute value of -9 on the number line.
Solution:
1)
The absolute value of a number can also be thought of as the distance from zero along the number line of a real number.
|7|=7
The absolute value of '7' is 7.
This is because the distance from zero to 7 on the number line is seven units.
The statement B is true.
2)
The absolute value of -9:
|-9|=9
The absolute value of -9 on the number line will be 9 units from zero.

Jim and Em baked 33 macaroons.
Jim baked 5 more macaroons than Em. How manymacaroons did Jim bake?
Answer: 19 macaroons
Step-by-step explanation:
Let's create an equation to represent this situation. Let x represent the number of macaroons that Em made.
33=x+x+5
33=2x+5
33-5=2x+5-5
28=2x
28/2=2x/2
14=x
This means that Em made 14 macaroons.
14+5=19
Therefore, Jim baked 19 macaroons.

The front of a house is in the shape of a hexagon with two right angles.
The other four angles are all the same size.
Calculate the size of one of these angles.
Answer: 135°
Step-by-step explanation:
The sum of the interiors angles of the hexagone is (6-2)*180°=720°
Two angles are right: 2*90°=180°
The sum of the four angles is 720°-180°=540°
Each angle is 540°/4= 135°

what equation represents the line that passes through the points (7,15) and (-4,4)?
Equation of line is y = mx +b
Passing through (-3,7 )
X= -3, y= 7
plug in these
7 = -3m + b ... .Eq1
Also X = 4 , y= 10
10 = 4m + b ............... Eq 2
Solve Eq 1 and Eq 2 for m and b
m= 3/7
b= 58/7
Thus y =( 3/7) X + 58/7 is equation of line

Use the drop-down menus to complete the statements about whether each student's
answer is an equivalent expression.
Then choose an expression that is equivalent
Answer:
Tessa's expression is false because -7 times -4 is positive 28, not -28.
Bernette's expressionis false because you must distribute the -7 before subtracting 7 from 2 (peMdas)
Lucy's expression is true because she correctly distributed the -7 to each of the terms in the parentheses and used PEMDAS.
2-21x+28
The equivalent expression for the given expression is 2-21x+28.
What is an equivalent expression?Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.
Tessa:
2-7(3x-4)=2-21x-28
Tessa's equivalent expression is wrong. Because -7×(-4)=28 not -28.
Bernette:
2-7(3x-4)=-5(3x-4)
Bernette's equivalent expression is wrong. Because, you can not 2 and 7, since 7 is multiplied to the term 3x-4
Lucy:
2-7(3x-4)=2-21x+28
Lucy's equivalent expression is correct.
Therefore, the equivalent expression is 2-21x+28.
