There are GCF of two numbers is three and the LCM is 180. If one of the numbers is 45,what is the other number ?
Answer:
The other number is 12
Step-by-step explanation:
There are GCF of two numbers is three and the LCM is 180. If one of the numbers is 45,what is the other number ?
Let us represent the other number as x
There are GCF of two numbers is three and the LCM is 180.
Therefore:
45 × x = 3 × 180
45x = 3 × 180
x = 3 × 180/45
x = 12
Therefore, the other number is 12

A 381 foot cable runs from the top of a radio tower to a skate in the ground. If it hits the ground 167 feet from the base of the tower , what is the angle of elevation that is makes with the ground?
Answer:
64°
Step-by-step explanation:
Using Pythagoras rule :
Cosθ = adjacent / hypotenus
Adjacent = 167
Hypotenus = 381
Cosθ = 167 / 381
Cosθ = 0.4383202
θ = Cos^-1(0.4383202)
= 64.003
Hence, angle of elevation = 64°

4 (X+7) = 38
WHAT IS X AND EXPLAIN HOW YOU KNOW
Answer:
X=2.5
Step-by-step explanation:
38÷4 = 9.5
9.5 - 7=2.5
Divide each side by four to get rid of that numbr from the elft and subtract seven from both sides to get rid of the seven so your left with x=2.5
Answer:
X is 2.5
Step-by-step explanation:
4÷4=1
38÷4=9.5
9.5 - 7=2.5
Therefore X is 2.5

16. Physical Science A ball is dropped from a
height of 500 meters. The table shows the height
of each bounce, and the heights form a geometric
sequence. How high does the ball bounce on the
8th bounce? Round your answer to the nearest
tenth of a meter.
Ball will bounce 83.9 meters high on the 8th bounce.
Geometric sequence:
nth term of a geometric sequence is given by the expression,[tex]T_n=ar^{n-1}[/tex]
Here, [tex]a=[/tex] First term
[tex]r=[/tex] Common ratio in each term
[tex]n=[/tex] Number of term
From the table attached,
First term [tex]a=400[/tex] meters Common ratio [tex]r=\frac{\text{Second term}}{\text{First term}}[/tex][tex]=\frac{320}{400}[/tex]
[tex]=0.8[/tex]
8th term of the sequence will be,
[tex]T_8=400(0.8)^{8-1}[/tex]
[tex]T_8=83.886[/tex]
[tex]\approx 83.9[/tex] meters

Solve this equation.
-4 (y - 3) = 36
-4y + 12 = 36
-4y = 24
y = - 6
Answer:
y = -6
Step-by-step explanation:
To solve for y, you must isolate the variable by first dividing both sides by -4:
-4 (y-3) = 36
÷-4
y-3 = -9
Next, add 3 to both sides and you will get your final answer:
y-3 = -9
+3
y = -6
To check your answer, you can plug in -6 for y to ensure that the overall result is 36:
-4(-6-3) = -4(-9) = 36
36 = 36

Two flag poles at Liberty Park are 27 feet tall. The distance from the top of one flag pole to the base of the other is 45 feet. What is the distance between the two flag poles?
Answer:
Step-by-step explanation:
Answer:
The distance between the two poles is 36 feet.
Step-by-step explanation:
If 2 flag poles are 27 feet tall each
if the distance from one flag pole to the base of the other flag pole is 45 feet, this forms the shape of a right angle triangle.
Here, we are going to make use of the Pythagoras theorem.
a2 + b2 = c2
27 2 + b2 = 45 2
b2 = 45 2 - 27 2
b = 45 2 - 27 2 (square root)
b = 2025 - 729
b= 1296 (square root)
b = 36

What is the value of expression below -8.125 + 7 3/8
Answer:-6/8, -3/4, -0.75
Step-by-step explanation:
Background info:
0.125=1/8
An you can also use the commutative property to "flip" the equation
Let's rewrite -8.125 as 8 1/8 because we know 1/8=0.125
And let's write it as a improper fraction - 65/8 and let's write 7 3/8 too as 59/8
Now we have to use the distributive property and subtract 65/8 from 59/8 (59/8 - 65/8) and you will get -6/8 or simplified -3/4 or in decimal -0.75

Answer:
120°
Step-by-step explanation:
If the line were to continue down to form a triangle at the bottom, it would cross the line with an interior angle of 70°. Since we have two of the angles, we subtract them from 180°.
180-70-50=60°
That would be the third interior angle at the top of the triangle. Angle x is supplementary to that.
180-60=120°
