Jimy traveled the entire route of the parade, but his suster Jemima only traveled along Elm Street. How much further did Jimmy travel than Jemima?
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]Jimmy \to[/tex] Entire Route
[tex]Jemima \to[/tex] Elm Street
Required
How much more did Jim travel
The question is incomplete, as the resources to calculate the distance covered by both are not given.
To solve a question like this;
First, calculate the distance by both, then subtract the smaller distance
Take for instance, after calculating the distance, you have:
[tex]Jimmy= 850m[/tex]
[tex]Jemima = 500m[/tex]
The difference d is:
[tex]d = 850m - 500m[/tex]
[tex]d = 350m[/tex]
i.e. Jimmy traveled 350m much more
If p(x) = x 3 + x 2+ root 5 x + root 5 , then find p( – 5 )
Answer:
-100-4√5
Step-by-step explanation:
Given the polynomial expression
p(x) = x³+x²+√5x + √5
p(-5) = (-5)³+(-5)² + √5(-5) + √5
p(-5) = -125 + 25 -5√5 + √5
p(-5) = -100-4√5
This gives the required answer
Find the slope and y-intercept of the line 4x - 2y = 8
Answer:
The slope is 2 and the y intercept is (0, -4)
Step-by-step explanation:
Put the line in slope intercept form, y = mx + b, where m is the slope and b is the y intercept.
4x - 2y = 8
Subtract 4x from both sides
4x - 2y = 8
-2y = -4x + 8
Divide each side by -2
y = 2x - 4
So, the equation in slope intercept form is y = 2x - 4.
The slope is 2 and the y intercept is (0, -4)
Jamie ran the first 2000 meters in 6 minutes. At that rate, how long would it take Jaime to run 5000 meters?
Answer:
15 minutes
Step-by-step explanation:
To figure this out, you can create a ratio. If we say the first 2000 miles is the 1 in the ratio, the ratio would be 1 : 2.5. Since it took 6 minutes for the first 2000, you have to multiply 6 by 2.5 to get your answer of 15 minutes.
Solve the following equation: 3 x squared = negative 12 a. x = 2 b. x = negative 2 c. No real solutions d. x = plus-or-minus 2
The value of solution of the equation is,
⇒ No real solution
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ 3x² = - 12
Now, We can simplify as;
⇒ 3x² = - 12
Divide by 3;
⇒ x² = - 12/3
⇒ x² = - 4
⇒ x = √- 4
⇒ x = 2i
Thus, The value of solution of the equation is,
⇒ No real solution

What is an equation of the line that passes through the points (0, -3)(0,−3) and (-5, 3)(−5,3)?
Answer:
y = 6/5 x -3
Step-by-step explanation:
Standard equation of a line is expressed as;
y = mx+b
Slope m = y2-y1/x2-x1
Given the coordinates (0, -3)and (-5, 3)
Slope m = 3-(-3)/-5-0
Slope m = 6/5
Since the line cuts the y axis at y = -3, hence b = -3
GEt the required equation;
Recall that y = mx+b
y = 6/5 x + (-3)
y = 6/5 x -3
This gives the required equation
Answer: −6/5x-3

B is the midpoint of AC. if AB = x+5 and BC = 2x-11, find the measure of AB
Answer:
2 is the answer
Step-by-step explanation:
Answer:
AB = 21
Step-by-step explanation:
Since B is the midpoint of AC , then
BC = AB
2x - 11 = x + 5 ( subtract x from both sides )
x - 11 = 5 ( add 11 to both sides )
x = 16
Then
AB = x + 5 = 16 + 5 = 21

Given that 4, 5x and 16 are the first three terms of geometric progression
Find:
(1)
the possible values of x,
(2)
the sum of the first ten terms if all the terms are positive.
Answers:
x = -8/5 or x = 8/5
Sum of the first ten terms where all terms are positive = 4092
========================================================
Explanation:
r = common ratio
first term = 4second term = (first term)*(common ratio) = 4rthird term = (second term)*(common ratio) = (4r)*r = 4r^2The first three terms are: 4, 4r, 4r^2
We're given that the sequence is: 4, 5x, 16
Therefore, we have these two equations
5x = 4r4r^2 = 16Solve the second equation for r and you should find that r = -2 or r = 2 are the only possible solutions. If r = -2, then 5x = 4r solves to x = -8/5. If r = 2, then 5x = 4r solves to x = 8/5.
-----------------
To find the sum of the first n terms, we use this geometric series formula
Sn = a*(1 - r^n)/(1 - r)
We have
a = 4 = first termr = 2, since we want all the terms to be positiven = 10 = number of terms to sum upSo,
Sn = a*(1 - r^n)/(1 - r)
S10 = 4*(1 - 2^10)/(1 - 2)
S10 = 4*(1 - 1024)/(-1)
S10 = 4*(-1023)/(-1)
S10 = 4092

Angle
y
= 96° and angle
z
= 52°.
Work out
x
Answer:
x = 136°
Step-by-step explanation:
We can use a theorem to help us.
Theorem:
The measure of an exterior angle of a triangle is equal to the sum of the measures of the remote interior angles.
For exterior angle x, the remote interior angles are z and <CBD.
From the theorem, we get this equation.
x = z + m<CBD
We know z = 52°.
We need to find m<CBD.
Angles CBD and y are a linear pair. They are supplementary, so the sum of their measures is 180°. We are given y = 96°.
m<CBD + y = 180°
m<CBD + 96° = 180°
m<CBD = 84°
x = z + m<CBD
x = 52° + 84°
x = 136°
Answer:
x = 136°
Step-by-step explanation:
∠ABD = y = 96°, ∠ABD + ∠DBC must be equal to 180° because they form a straight angle.
[tex]y + B = 180\\96 + B = 180\\B = 180 - 96 = 84[/tex]
∠BDC = z = 52° and ∠DBC = B = 84.
Angles ∠BDC, ∠DBC, and ∠BCD must have a sum of 180° because the sum of the interior angles in a triangle is 180°.
[tex]180=(180 - y) + 52 + C\\180=(180 - 96) + 52 + C\\180 - (52 + 84) = C\\C = 44[/tex]
The interior angle at C is 44. Line DCE forms a straight line, therefore having an angle of 180°. To find x, the sum of x and interior angle C is 180°.
[tex]180 = C + x\\180 = 44 + x\\x = 180-44\\x = 136\\[/tex]
Angle ∠BCE = x = 136.

the product of two fractions is 2/3. One fraction is 3/5. what is the other fraction
Answer:
10 / 9
Step-by-step explanation:
Let's suppose the other fraction is x. We are given 3 / 5 * x = 2 / 3
We can divide by 3 / 5 on both sides, which is the same as multiplying 5 / 3 on both sides:
5 / 3 * 3 / 5 * x = 2 / 3 * 5 / 3
This simplifies to:
x = 10 / 9
