Th GCF of two numbers is 3 and the LCM is 180. If one of the other number is 45, what is the other numbers?
Answer:
x = 12
Step-by-step explanation:
Given that,
GCF of HCF of two numbers = 3
LCM of numbers = 180
First number = 45
Let another number be x.
So,
HCF×LCM = first number × second number
[tex]x=\dfrac{3\times 180}{45}\\\\x=12[/tex]
So, the other number is 12.

Answer:
$1.75
Step-by-step explanation:
4b+n=12;2b+3n=18.5
Step: Solve4b+n=12for n:
4b+n+−4b=12+−4b(Add -4b to both sides)
n=−4b+12
Step: Substitute−4b+12fornin2b+3n=18.5:
2b+3n=18.5
2b+3(−4b+12)=18.5
−10b+36=18.5(Simplify both sides of the equation)
−10b+36+−36=18.5+−36(Add -36 to both sides)
−10b=−17.5
(Divide both sides by -10)
b=1.75
Step: Substitute1.75forbinn=−4b+12:
n=−4b+12
n=(−4)(1.75)+12
n=5(Simplify both sides of the equation)
Answer:
b=1.75 and n=5

Answer:
x= 8.5, 2x=17, (9x+5)=81.5
Step-by-step explanation:
since the sum of the interior angles of a triangle is 180 degrees, you must add all of the angles and set them equal 180:
[tex]2x + 2(9x+5) = 180[/tex]
next distribute the 2 to 9x + 5.
[tex]2x + 18x + 10 = 180[/tex]
next combine like terms (2x and 18x) and subtract 10 from 180.
[tex]20x = 170[/tex]
finally, divide 170 by twenty.
[tex]\frac{20x = 170}{20}\\,x=8.5[/tex]
the final answer is x=8.5
once x is determined, you can solve 2x and 9x+5.
[tex]2(8.5)=17\\\\9(8.5) +5 =81.5[/tex]

Work Shown:
Because segment GI is parallel to segment TA, this means triangle VGI is similar to triangle VTA.
From that we can set up the proportion
VG/VT = VI/VA
which breaks down into
VG/(VG+GT) = VI/(VI+IA)
Let's plug in the given values. Let x be the length of segment IA.
Let's solve for x
VG/(VG+GT) = VI/(VI+IA)
72/(72+61) = 95/(95+x)
72/133 = 95/(95+x)
72(95+x) = 133*95 ......... cross multiply
6840+72x = 12635
72x = 12635-6840
72x = 5795
x = 5795/72
x = 80.4861111111111 ......... which is approximate
x = 80.49 ......... rounding to the nearest hundredth
The length of IA is roughly 80.49 units. This is not the final answer. The fact that 80.49 is listed as one of the answer choices seems to imply your teacher put it as a trick answer.
Since we found IA = 80.49, this means,
VA = VI + IA
VA = 95 + 80.49
VA = 175.49
This is the length of segment VA, which is the same as segment AV.
-----------------------------
Here's a slightly similar way to solve:
VT = VG+GT = 72+61 = 133
VG/VT = VI/VA
72/133 = 95/x
72x = 133*95
72x = 12635
x = 12635/72
x = 175.486111111111
x = 175.49 is the approximate length of segment AV.
The coorrdinate grids show the cost of different numbers of bookmarks .How many cents do 4 bookmarks cost?
Answer:
54 cents
Step-by-step explanation:
The cost of bookmarks relating to the number of bookmarks is shown in the coordinate grid. x represents the number of bookmarks and y represents the cost of each bookmark in cents.
The equation of a line passing through the points [tex](x_1,y_1)\ and\ (x_2,y_2)[/tex] is given by:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
From the coordinate grid, it has the points (2, 30) and (7, 90). Therefore, the equation is:
[tex]y-30=\frac{90-30}{7-2}(x-2)\\\\y-30=12(x-2)\\\\y-30=12x-24\\\\y=12x+6[/tex]
Therefore the cost of 4 bookmarks (x = 4):
y = 12(4) + 6
y = 48 + 6
y = 54 cents

5. A= length x width
Answer:
Step-by-step explanation:
Circle - A = πr²
Semi circle - A= 1/2 πr²
Trapezoid - A= 1/2 (base 1 + base 2 ) x height
Rectangle - length x width
Triangle - A= 1/2 base x height
Answer:

Step-by-step explanation:
A) Trapezoid
3. A = 1/2 (base 1 + base 2 ) x height
~
B) Circle
1. A = πr²
~
C) Rectangle
5. A = length x width
~
D) Semicircle
4. A = 1/2 πr²
This is half of a circle, so it would be 1/2 of the area of a circle, hence the 1/2.

E) Triangle
2. A = 1/2 base x height
If you cut a rectangle in half diagonally, you have two triangles. So it's half the area of a rectangle. This is one way to think about it, hence the 1/2.
The straight line, Line L has an equation of 4x+y=7. Find the equation of the straight line perpendicular to Line L that passes through (-8,3)
Answer:
Step-by-step explanation:
y = -4x + 7
perp. 1/4
y - 3 = 1/4(x + 8)
y - 3 = 1/4x + 2
y = 1/4x + 5
The equation of the perpendicular line is y = 1/4x + 5
How to determine the line equation?The equation is given as:
4x + y = 7
Make y the subject
y = -4x + 7
A linear equation is represented as:
y = mx + c
Where m represents the slope.
This means that:
m = -4
A line perpendicular to 4x + y = 7 will have a slope of:
Slope = -1/m
This gives
Slope = 1/4
The equation of the line is then calculated as:
y = Slope(x - x1) + y1
This gives
y = 1/4(x + 8) + 3
Expand
y = 1/4x + 2 + 3
Evaluate
y = 1/4x + 5
Hence, the equation of the perpendicular line is y = 1/4x + 5

Answer:
15m
Step-by-step explanation:
Since the square has an area of 9m^2 it has to have sides that are 3m. There are 3 sides that are 3m. An equilateral triangle has the same sides so it has 2 sides that are 3m. There are 5 sides that are 3m. The perimeter is 15m.
Each time you take your dog to the dog park it costs $1.75. Write an expression that represents the cost of n visits to the dog park.
Answer:
1.75n
For each visit it costs 1.75, so n visits would be the product of the two.
Step-by-step explanation:
Answer:
1.75n
Step-by-step explanation:
"every time" means multiplication.
Total cost is $1.75 multiplied by n number of trips.
(for instance, if you take 3 trips, it would be 1.75+1.75+1.75, or 1.75*3)
The measure of the second angle is 15 degrees more then the measure of the 1st angle. The measure of the 3rd angle is 45 degrees more than the measure of the 1st angle. Find the measures of the interior angles in the triangle.
Let the first angle be x
So, second angle = (x+15)°
and third angle= (x+ 45)°
Now,
x+ (x+15) + (x+45)= 180°. ( Triangle sum property)
x+x+x+15°+45° = 180°
3x+ 60° = 180°
3x= 180°-60°
3x= 120°
x= 120°/3
x= 40°
Now,
first angle=x= 40°
second angle = (x+15)°= 40°+15° = 55°
third angle= (x+45)° = 40°+45° = 85°

what is the probability of drawing two yellow marbles if the first one is placed back in the bag before the second draw. give your answer as a ratio reduced to simplest terms.
The probability that both marbles are yellow marbles is 1/25
How to determine the probability?The given parameters are:
Yellow = 2
Total = 10
The probability of selecting the first yellow marble :
P(Yellow) = 2/10
When the marble is returned, we have:
Yellow = 2
Total = 10
The probability of selecting the second yellow marble :
P(Yellow) = 2/10
The required probability is:
P = 2/10 * 2/10
Evaluate
P = 4/100
Simplify
P = 1/25
Hence, the probability that both marbles are yellow marbles is 1/25

An angle measures 170° less than the measure of its supplementary angle. What is the measure of each angle?
Given:
An angle measures 170° less than the measure of its supplementary angle.
To find:
The measure of each angle.
Solution:
Let x be the measure of supplementary angle.
Then, the measure of the angle is (x-170°).
Sum of supplementary angles is 180 degrees. So,
[tex]x+(x-170^\circ)=180^\circ[/tex]
[tex]2x-170^\circ=180^\circ[/tex]
[tex]2x=180^\circ+170^\circ[/tex]
[tex]2x=350^\circ[/tex]
Divide both sides by 2.
[tex]x=\dfrac{350^\circ}{2}[/tex]
[tex]x=175^\circ[/tex]
Now, the measure of the angle is
[tex]175^\circ-170^\circ=5^\circ[/tex]
Therefore, the measure of angle is 5° and the measure of its supplementary angle is 175°.
