suppose M is the midpoint of FG. find each missing measure.
FM= 8a + 1, FG = 42, a =?
The value of a is 2.5
As FG is the line and M is the midpoint of the line
F ______________·_________________G
M
So by this, we have that
FG = FM + MG
Where FM = MG as M is the midpoint of the line.
Therefore FG = 2FM
As it is given that FM = 8a + 1 and FG = 42
Now putting the values we have
42 = 2( 8a + 1)
21 = 8a + 1
20 = 8a
a = 2.5
Therefore the value of a is 2.5.

Consider the system of equations 2x + 5y = 5 and -3x + 7y = 7. What number would you multiply to eliminate the y?
Answer:
(0, 1 )
Step-by-step explanation:
2x + 5y = 5 → (1)
- 3x + 7y = 7 → (2)
to eliminate y multiply (1) by 7 and (2) by - 5 , then add the result
14x + 35y = 35 → (3)
15x - 35y = - 35 → (4)
add (3) and (4) term by term to eliminate y
29x + 0 = 0
29x = 0 ⇒ x = 0
substitute x = 0 into (1) and solve for y
2(0) + 5y = 5y
0 + 5y = 5
5y = 5 ( divide both sides by 5 )
y = 1
solution is (0, 1 )
Find FH
FH = {Blank}
Answer:
FH = 24
Step-by-step explanation:
HG = 13
FH = 37 - 13
= 24
Answer:
The value of FH is 24.
Step-by-step explanation:
The equation will be,
→ FHG = FH + HG
Then the value of FH will be,
→ 37 = FH + 13
→ FH = 37 - 13
→ [ FH = 24 ]
Hence, the value of FH is 24.
Write the specified quantity as a function of the specified variable. It will help in each case to draw a picture. The height of a right circular cylinder equals its diameter. Write the volume of the cylinder as a function of its radius.
The volume of the cylinder as a function of its radius is V = 2πr^3
How to write the volume of the cylinder as a function of its radius?The given parameters are
Diameter = Height
This can be represented as
d = h
The radius of a cylinder is calculated as
r = d/2
This means that
d = 2r
Substitute d = 2r in d = h
h = 2r
The volume of a cylinder is
V = πr^2h
Substitute h = 2r in V = πr^2h
V = πr^2(2r)
Evaluate
V = 2πr^3
Hence, the volume of the cylinder as a function of its radius is V = 2πr^3

Which of these is a non-real complex number?
Quadrilateral ABCD has the following angle measures:
m∠A = 105°, m∠B = ?°, m∠C = 34°, m∠D = 90°
What is m∠B?
pleeeeease help!!
Answer:
131°
Step-by-step explanation:
Sum of all angles of a quadrilateral = 360°
We can find the unknown angle ∠B, by subtracting the sum of the angles ∠A, ∠C, ∠D from 360°.
∠A + ∠B + ∠C + ∠D = 360
105 + ∠B + 34 + 90 = 360
∠B + 229 = 360
∠B = 360 - 229
∠B = 131°
Answer:
The measure of m<GHE is 49°, the correct option is B.
What is a Quadrilateral?
A quadrilateral is a polygon with four sides.
It is of various types,
Trapezoid, which have one pair of parallel sides,
Parallelogram, it has two pairs of parallel sides,
Rhombus, it has all sides equal,
Rectangle, opposite sides are parallel and equal, and,
Square, all sides are equal and opposite sides are parallel, and all angles have measure of 90 degree.
The quadrilateral ABCD is ≅ quadrilateral EFGH
When two figures are congruent then by CPCTC, corresponding parts of congruent figures are congruent.
The measure of the angle
B = m<BCD = 90°
m<BAD = 131°
As the quadrilaterals are congruent,
By CPCTC
∠F = ∠FGH = 90°
m ∠FEH = 131°
The measure of m<GHE has to be determined.
The sum of the measures of all angle so of a quadrilateral is 360 degree.
The ∠F + ∠FGH + ∠FEH + ∠GHE = 360
90 +90+ 131 +∠GHE = 360
∠GHE = 49°

An investigator wants to test for the presence of simple sugars in a sample. She adds reagent to her sample and also to a sample of distilled water. What reagent should she have added?.
The investigator can test the presence of simple sugars in the sample by using Benedict's solution.
What is Benedict's test ?Simple carbs are tested for using Benedict's Test. With free ketone or aldehyde functional groups, reducing sugars (monosaccharides and some disaccharides) are recognized by the Benedict's test.
What is Benedict's solution?Benedict's solution turns orange or brick red when heated in the presence of simple carbohydrates. The reducing characteristic of simple carbs is what triggers this response. The Benedict's solution changes color as a result of the reduction of copper (II) ions to copper (I) ions.
The produced red copper(I) oxide precipitates out of solution because it cannot be dissolved in water. This explains how the precipitate was created. The closer the final hue is approaching brick-red and the more precipitate is generated as the reducing sugar concentration rises. Copper oxide, a brick-red solid, can occasionally precipitate out of a solution and gather at the test tube's bottom.

Slope: m = (y2-y1)/(x2-x1)
m = (16 - 5)/(9 - 0) = 9/9 = 1
Using m = 1, y = 5, x = 0
then y = mx + b
5 = 1(0) + b

Aliza needs to run at a rate faster than 8.2 feet per second in order to exceed her fastest time in a race. After running for 15 minutes, her coach determines that she is running at an average rate of 5.8 miles per hour. He converts the average rate to feet per second as shown below:
He concludes that she is not running fast enough to exceed her fastest time.
Coach's errors are;
Wrong conversion when converting hour to seconds
There is wrong conclusion since Eliza was running fast enough at a speed of 34ft/s compared to 8.8ft/s
The speed required by eliza is 8.8 ft/s
Converting 5.8miles to feet per second
Taking the coach conversion
This shows that 5.8mi/hr is equivalent to 34.0ft/s in accordance with coach conversion rate.
The coach made the first error by taking 60s as 1hr instead of 3600s as 1hr
The mistake that Eliza is not running fast enough to exceed her fastest time. Eliza is running at pace as her speed at 34ft/s exceed 8.8ft/s.
Hence the second error was the wrong conclusion made by the coach.

The compound inequality to determine the Fahrenheit temperature range is given by [tex]-40 < \frac{5}{9}(F-32) < 125[/tex] .
An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way. The most frequent application is to size-compare two numbers on a number line.
Inequality is represented by:
The notation x < y means that x is less than y.The notation x > y means that x is greater than y.The notation x ≤ y or x ⩽ y means that x is less than or equal to y The notation x ≥ y or x ⩾ y means that x is greater than or equal to yA compound inequality is of the form : a < x < b implies that the value of x lies between the values of a and b.
According to the question if temperature is denoted in Celsius the inequality can be written as : -40° < °C < 125°
Now we know that the relation between C and F can be written as

If m ∠ E B C = 3 r + 10 ° and m ∠ A B E = 2 r − 20 ° , find m ∠ E B F .
The measure of ∠EBF is 56°.
Here, we are given that-
m ∠EBC = 3 r + 10 °
and m ∠ABE = 2 r − 20 °
Also we can observe that ∠EBC and ∠ABE are angles on a straight line and hence will be supplementary.
⇒ ∠EBC + ∠ABE = 180
⇒ 3r + 10 + 2r - 20 = 180
5r - 10 = 180
5r = 180 + 10
5r = 190
r = 190/5
r = 38
Thus, ∠ABE = 2(38) - 20
= 76 - 20
= 56
Now, from the figure, m ∠EBF = m ∠ABE
⇒ m ∠EBF = 56°
Thus, the measure of ∠EBF is 56°.

2. If y = 6, find the values of and z.
x
4x+y=z=15
x + 2y + z = 38
The solution to the system of equation is x = 6, y = 4, z = 5
The equation is
1.5x + y - z = 8
x + 3y = 18
2y + z = 13
From this we have,
y = 8 - 1.5x + z
x + 3y = 18
2y + z = 13
x + 3(8 - 1.5x + z) = 18
2(8 - 1.5x + z) + z = 13
Apply the Distributive Property
x + 24 - 4.5x + 3z = 18
16 - 3x + 2z + z = 13
Combine like terms
-3.5x + 24 +3z = 18
16 - 3x + 3z = 13
Rearrange variables to the left side of the equation
-3.5x + 3z = 18 - 24
-3x + 3z = 13 - 16
Subtract the two equation
-3.5x + 3z - (-3x + 3z ) = 18-24 - ( 13-16)
-3.5x + 3z + 3x -3z = 18 - 24 - 13 + 16
-3.5x + 3x = 18 - 24 - 13 + 16
x = 6
Substitute the value of x in one of the equation
-3×6 + 3z = 13 - 16
-18 + 3z = -3
3z = 15
z = 5
Now put the value of x and z
y = 8 - 1.5x + z
y = 8 - 1.5×6 + 5
= 8 -9 + 5

A square field has an area of 22,500 square feet. To the nearest foot, what is the diagonal across the field?
The length of the diagonal across the field is 212.132 feet.
What is a square?A rectangle whose all sides are equal is called a square.
A square is always a rectangle, parallelogram, and a quadrilateral but its reverse statement may or may not be true.(ie it is not always necessary that a rectangle is a square or a parallelogram is a square).
Given that a square field has an area of 22,500 square feet. Now, the length of the side of the square field can be written as,
Area of the square field = (Length of square field)²
22,500 square feet = (Length of square field)²
Length of square field = √(22,500 sq. feet)
Length of square field = 150 feet
Now, the length of the diagonal of the field can be written as,
(Length of the diagonal)² = 2(Length of the side of square field)²
(Length of the diagonal)² = 2(150²)
(Length of the diagonal)² = 45,000 sq. feet
(Length of the diagonal) = 212.132 feet
Hence, the length of the diagonal across the field is 212.132 feet.
