Answer:
89 meters
Step-by-step explanation:
We know it's 9 + "the height of the triangle".
Fortunately, the height of the triangle (let's call it y) can be computed from:
y^2 + 18^2 = 82^2 (Pythagoras theorem).
y^2 = 82^2 - 18^2 = 6724 - 324 = 6400
y = 80 (or y = -80 but it doesn't make sense in geometry).
so x = y + 9 = 89;
Find the equation of the line by using y=mx+b
I tried to put the answer but it keeps asking for more
Answer:
Step-by-step explanation:
y=mx+b
m=(y2-y1)/(x2-x1), we have points (-3,6) and (9,-5)
m=(-5-6)/(9-(-3))
m=-11/12 so now we have
y=-11x/12+b, using point (9,-5) we can solve for b
-5=-11(9)/12+b
-5=-99/12+b
b=39/12
y=(-11x+39)/12
That is the line, m=-11/12 and b=39/12 or as a decimal b=3.25. You had b so not sure what the problem is. Though the question in the picture asks what the line is. The line is
y=-11x/12+13/4 so maybe they want the entire function instead of entering what b is.
Bridget is saving for a bike that costs $550. She has $150 in her savings account and saves $40 per month. How many months will it take Bridget to save enough money to buy the bike?
Answer:
9 months im pretty sure hoped this help
Answer: It would take 10 months for her to get enough money to but the bike.
Step-by-step explanation: 150 + 400 = 550.
$40 per month - 40 x 10 = 400.
Already has 150$ in account.
150 + 400 = 550.

3x+2y=7 y=3x-19 could someone show me a step by step for this equation for substitution
Answer:
[tex]\boxed {\boxed {\sf (5,-4)}}[/tex]
Step-by-step explanation:
We are given the equations:
[tex]3x+2y=7 \\y=3x-19[/tex]
Since we know what y is equal to, we can substitute that expression in for y in the first equation.
[tex]3x+2(3x-19)=7[/tex]
Distribute the 2. Multiply each term inside the parentheses by 2.
[tex]3x+(2*3x)+ (2*-19)=7[/tex]
[tex]3x+6x+-38= 7[/tex]
Combine the like terms (the terms with variables).
[tex]9x-38=7[/tex]
Since we are solving for x, we must isolate the variable. 38 is being subtracted and the inverse of subtraction is addition. Add 38 to both sides.
[tex]9x-38+38=7+38 \\9x=7+38\\9x=45[/tex]
Now x is being multiplied by 9. The inverse of multiplication is division. Divide both sides by 5.
[tex]9x/9=45/9\\x=45/9\\x=5[/tex]
Now we know what x is equal to and can substitute the value into the second equation.
[tex]y=3x-19[/tex]
[tex]y=3(5)-19[/tex]
Multiply.
[tex]y=15-19[/tex]
Subtract.
[tex]y= -4[/tex]
Coordinate points are written as (x,y). Therefore, the solution is (5, -4).
Answer:
x=5,y=-4
Step-by-step explanation:
[[tex]\frac{3x+2y=7}{y=3x-19}[/tex]][3x+2(3x-19)=7][9x-38=7]y=3 · 5 - 19x=5,y=-4if the two adjacent angles are supplementary then their outer sides are???
Answer:
If the bisectors of two adjacent angles are perpendicular to each other, are the angles then supplementary angles?
Suppose two angles ABC and CBD are x and y.
x+y = 180 deg.
The bisector of angle ABC (BE) and the bisector of angle CBD (CF) will form angle EBF = (x/2)+(y/2) = 180/2 = 90 deg.
Conclusion: If the angle bisectors of two adjacent angles are perpendicular to eaxh other, the adjacent angles are supplementary angle
Adjacent angles are when the 2 angles have a common vertex and a common arm.
if the exterior sides of 2 adjacent angles are perpendicular, then the angles are complementary angles.
Then the sum of the 2 adjacent angles is a right angle - 90°.
When 2 angles add up to 90°, they are called a pair of complementary angles.

Show your work for full credit. You are finding the measure of angle A, side length of AC and side
Show Your Work

Answer:
A = 20°
AC = 6.6
BC = 2.4
Step-by-step explanation:
Given:
B = 70°
C = right angle = 90°
AB = 7
Required:
A, AC, and BC
Solution:
✔️A = 180 - (90 + 70) (sum of triangle)
A = 20°
✔️Use trigonometric function to find AC:
Refernce angle = 70°
Opp = AC
Hypotenuse = 7
Apply SOH,
sin 70 = Opp/Hyp
sin 70 = AC/7
7 * sin 70 = AC
6.57784835 = AC
AC = 6.6 (nearest tenth)
✔️Use trigonometric function to find Bc:
Refernce angle = 70°
Adj = BC
Hypotenuse = 7
Apply CAH,
cos 70 = Adj/Hyp
cos 70 = BC/7
7 * cos 70 = BC
2.394141 = BC
BC = 2.4 (nearest tenth)

find the volume of the sphere
The volume of the sphere is 22/ 336 cubic units
How to determine the volumeThe formula for volume of a sphere is expressed as;
Volume = [tex]\frac{4}{3} \pi r^3[/tex]
Where;
π = 22/ 7radius, r = 1/ 4Substitute the values into the formula;
Volume = 4/ 3 × 22/ 7 × (1/ 4)³
Volume = 4/ 3 × 22/ 7 × 1/ 64
Multiply through
Volume = 88/1344
Volume = 22/ 336 cubic units
Thus, the volume of the sphere is 22/ 336 cubic units

Find the circumference of a circle that has an area of 153.86 cm.
Answer:
C=[tex]14\pi[/tex] or ≈43.96cm
Step-by-step explanation:
Start by figuring out the Area of the circle to get the radius (r)
Area (A)=153.86 cm
A=[tex]\pi r[/tex]²
153.86=[tex]\pi[/tex]r²
153.86÷[tex]\pi[/tex]=r²
49=r²
√49= r
r= 7cm
Next insert r=7cm into the Circumference equation of a circle
C=2[tex]\pi[/tex]r
C= 2×[tex]\pi[/tex]×7
C=14[tex]\pi[/tex] or C=43.96cm

Which situation is best represented by the equation y=5x + 10?
Answer:
x=1/5y-2
Step-by-step explanation:
Step 1: Flip the equation
5x+10=y
Step 2: Add -10 to both sides
5x+10+-10=y+-10
5x=y-10
Step 3: Divide both sides by 5.
5x/5 =y-10/5
x=1/5y-2

Solving systems of equations by graphing. how do you do this
Answer:
Solve systems of equations by graphing
A system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect.
Example
[tex]\left \{ {{y=2x+2} \atop {y=x-1}} \right.[/tex]
Graph the equations in a coordinate plane
The two lines intersect in (-3, -4) which is the solution to this system of equations.

Draw a line representing the “rise” and a line representing the “run” of the line. State the slope of the line in the simplest form.
Answer:
[tex]\frac{2}{3}[/tex]
Step-by-step explanation:
The slope is the "rise" over the "run" of the line, or in other words, the number of units the line travels upwards over the number of units the line travels to the right.
[tex]\frac{rise}{run}[/tex]
We can see that, on the graph, for every 3 units the line travels to the right, it travels 2 units up. Therefore, the rise is 2 while the run is 3.
[tex]\frac{2}{3}[/tex]
Therefore, the slope of the line is [tex]\frac{2}{3}[/tex].

Answer:
obtuse triangle
Step-by-step explanation:
it is obtuse because it needs to have all 3 sides to be acute to be an acute angle and it doesn't have any 90° angles so it has to be obtuse. Also because to be an obtuse it has to have 2 acute angles and 1 obtuse angle. Hope this helps!!
