Olga’s number is 4 times more than Anna’s. The sum of their numbers is 65. What are their numbers?
Hey there! :)
Answer:
Anna's number = 13.
Olga's number = 52.
Step-by-step explanation:
We can express this situation as an equation to solve for both of their numbers.
Let x be Anna's number
Let 4x be Olga's number
Their numbers sum up to 65, therefore:
4x + x = 65.
Begin by combining like terms:
5x = 65
Divide both sides by 5:
5x/5 = 65/5
x = 13 = Anna's number.
Find Olga's number by plugging 13 into 4x:
4(13) = 52. This is Olga's number.

find equation of vertical line through (-5, -3)
Answer:
x = -5
Step-by-step explanation:
Given that it is a vertical line, we know that it will only go through one x-value.
We are also given a point, (-5, -3).
This point tells us that the vertical line only goes through the x-value -5, so the equation will be x = -5.
and what is distance jeremy jumps from the ramp to the fire escape is _______ feet (round to the nearest tenth of a foot)
Answer:
sin(70°) =10/x
The distance Jeremy jumps from the ramp to the fire escape is 10.6 feet
Step-by-step explanation:
From the question shown in the picture attached, the vertical height Jeremy has to jump is: 15 - 5 = 10 ft
A right triangle is formed, where the angle between the hypotenuse (called x) and one of the legs is: 160° - 90° = 70°, and the vertical height Jeremy has to jump, is the leg opposite to that angle.
From sine definition:
sin(70°) = opposite/hypotenuse
sin(70°) = 10/x
x = 10/sin(70°)
x = 10.6 ft

The cost of 2 rubber stamps is $2.
We have given that rubber stamps cost $10.30
we have determined the cost of 2 rubber stamps.
We have to find the price per stamp.
What is the formula for the value price of one stamp?[tex]1 samp price=\frac{cost for all stamp }{total number of stamp}[/tex]
Therefore we get,

The length of a rectangular pool is 4yds longer than twice the width. If the area is 70 square yards, find the dimensions.
Answer: Found it by web and solving
Step-by-step explanation: L = W + 4
LW = 60
---
LW = 60
(W + 4)W = 60
W^2 + 4W + (-60) = 0
---
above is in quadratic equation form: ax^2 + bx + c = 0

use the quadratic formula to solve for two solutions:
x = ( -b +- sqrt( bb - 4ac ) ) / 2a
---
the two solutions are:
W = 6
W = -10
the negative solution doesn't make sense for length, so use the positive solution.

the dead sea is at an elevation of -1,360 feet. A seabirds flying over the dead sea at an elevation of -422 feet. if the bird lands on the dead sea, what will be its change in elevation
Answer:
- 938
Step-by-step explanation:
We can change these to positive just so its easier to work with
So 1360 - 422 = 938
since they are going down you just have to change the number to a negative.
The change in elevation is 938 feet.
To find the change in elevation.
What is elevation?The action or fact of raising or being raised to a higher or more important level, state, or position. Elevation is distance above sea level. Elevations are usually measured in meters or feet. They can be shown on maps by contour lines, which connect points with the same elevation; by bands of color; or by numbers giving the exact elevations of particular points on the Earths surface.
Given that:
Dead sea is at an elevation = -1,360 feet.
seabirds flying over the dead sea at an elevation =-422 feet.
Although when you have 2 negative numbers in a subtraction-elevation problem, the elevation difference won't be negative.
So, difference between the depth and the surface of the dead sea
= Dead sea is at an elevation - seabirds flying over the dead sea at an elevation
=-1360-(-422)
=-938 feet.
But that would just describe a regular negative subtraction problem, so it becomes 938 feet.
This answer is positive since it describe the distance between these integers.
So, the change in elevation is 938 feet.

The times for completing one circuit of a bicycle course are normally distributed with
a mean of 72.5 minutes and a standard deviation of 6.5 minutes. An association
wants to sponsor a race but will eliminate the bottom 75% of riders. In a trial run,
what should be the cutoff time?
Answer:
The answer is 76.9 rounded or rounds.
Step-by-step explanation:
Solution
Given that:
Mean = μ = 72.5
Standard deviation = σ = 6.5
Now
By applying the standard normal table we have the following:
P(Z < z) = 75%
= P(Z < z)
= 0.75
Thus
z =0.67 by using the standard normal z table
Applying the z-score formula we have:
x = z * σ + μ
x = 0.67*6.5+72.5
x= 76.855 ≈ 76.9
Therefore the cutoff time is 76.9 rounds.

The graph of y=ax^2+bx+c passes through points (0,5), (1,10), and (2,19). Find a+b+c.
Answer: a = 2 b = 3 c = 5
Literally a+ b+c = 10, but I don't think that's what the question means to ask.
the equation is 2x² +3x + 5
Step-by-step explanation: Substitute the values of the given coordinates into the formula and use algebra (solve a system of equations by substitution and elimination) to get the values of a,b & c
y=ax²+bx+c using (0,5), (1,10), and (2,19)
5=a(0)²+b(0)+c becomes 5= 0+0 + c .so we find c = 5
10=a(1)²+b(1)+c becomes 10 = a + b + c
19=a(2)²+b(2)+c . becomes 19 = 4a + 2b + c
Substitute the 5 for c. Then rewrite
10 = a + b + 5 becomes 5 = a+ b to eliminate b multiply this be (-2)
(-2)( 5 = a+ b) .to get -10 = -2a - 2b
19 = 4a + 2b + 5 becomes 14 = 4a + 2b
_______________ Add these two
14 = 4a + 2b
-10 = -2a - 2b this will eliminate the "b" term
4 = 2a divide both sides by 2 so you have a = 2
substitute in 10=a(1)²+b(1)+5 to find b
10=2(1)²+b(1)+5 .becomes 5 = 2 + b Subtract 2 from both sides
b = 3
So now you have all three values:
a = 2 b= 3 c = 5

Which best describes the relationship between the line that passes through the points
Answer:
Perpendicular (A)
Step-by-step explanation:
First find the gradient of the first line:
Change in y/ Change in x = -7-(-2)/ -9-(-12) = -5/3
Now find the gradient of the second line:
9-6/1-6 = -3/-5 = 3/5
When we multiply the gradient of two perpendicular lines we will get:
m1 x m2 = -1
If we multiply 3/5 and -5/3 we will get -1
Therefore it is perpendicular!

Describe any patterns you notice. Are the two expressions ever equal? Can one be greater than the other?
Answer:
Both expressions are equal. One expression cannot be greater than the others.
Step-by-step explanation:
The given expressions are:
A: (x + y)
B: (x) + (y)
Let x = a and y = bA: (a+b) = a+b
B: (a)+(b) = a+b
Let x = -a and y = -bA: (-a+ (-b)) = -a-b
B: (-a)+(-b) = -a-b
Let x = a and y = -bA: (a+(-b)) = a-b
B: (a)+(-b) = a-b
Let x = -a and y = bA: ((-a)+b) = -a+b
B: (-a)+(b) = -a+b
We can see the pattern that both expressions are always equal to each other, no matter what value of x and y you plug in. One expression cannot be greater than the other
In the diagram, what is the measure of angle 1 to the nearest degree? A transversal intersects 2 lines to form 8 angles. Clockwise from the top left, the angles are blank, 88 degrees, blank, (7 x + 4) degrees; blank, blank, (7 x minus 2) degrees, 1. 82° 92° 94° 98°
Answer:
98 degrees
Step-by-step explanation:
The measure of angle 1 is 92°
The correct option is B.
What is an angle measure?When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.
Given:
A transversal intersects 2 lines to form 8 angles.
Clockwise from the top left, the angles are blank, 88 degrees, blank, (7 x + 4) degrees;
blank, blank, (7 x minus 2) degrees, blank.
Now, the property of the supplementary angles:
m∠1 + m∠2 = 180°
m∠1 = 180 - 88
m∠1 = 92°
Therefore, the angle measure of angle 1 is 92°.
