Answer: When two lines are crossed by another line (which is called the Transversal), the angles in matching corners are called corresponding angles. Example: a and e are corresponding angles. When the two lines are parallel Corresponding Angles are equal.
please help me solve this problem!!!
Answer:
w = 9
Step-by-step explanation:
We can use ratios to solve
2 3
---- = ------
6 w
Using cross products
2w = 3*6
2w = 18
Divide by 2
w = 9
Four times the sum of half a number and 6 is 48.
How do you put this as an equation?
Answer:
make x the subject of formula then = 6/48
divide 9y power 2 by 3
divide (8x power 2 +4x ) by 2x
Answer:
1=27
2=34
Step-by-step explanation:
1)9y power 2÷3
or, y=9 power 2÷3
or, y=9×9÷3
or, y=81÷3
or, y=27
2) (8x power 2+4x)÷2
=(8x×8+4x)÷2
=(64x+4x)÷2
=68x÷2
or, x=68÷2
or, x=34
z = 73i - 32
What is the real part of z ?
What is the imaginary part of z?
Answer:
real: -32imaginary: 73Step-by-step explanation:
The real part is everything that does not multiply i. The imaginary part is everything that does multiply i.
Conventionally, the real part is written first:
z = -32 +73i
Re(z) = -32
Im(z) = 73
Which of the following options have the same value as %5, percent of 35? Choose 2 answers: (Choice A) A 5*35 (Choice B) B 5/100*35 (Choice C) C 0.5* 0.35 (Choice D) D 0.05*35 (Choice E) E 5/10*35
Answer:
B and D
Step-by-step explanation:
5% of 35 can be represented as 5% [tex]\cdot35[/tex].
To find equations that make this work, we need to find different ways to represent 5%.
5% can be represented as fraction - over 100. The percentage over 100 will be equal to the percent.
So, [tex]\frac{5}{100}[/tex]. Multiplying by 35 gets us [tex]\frac{5}{100}\cdot35[/tex]
This means that Choice B is correct.
Another way to represent 5% is as a decimal.
We already know that the fraction form of 5% is [tex]\frac{5}{100}[/tex]. This means that in the decimal, the number 5 will be two place values to the right of the decimal place.
0.05
So the decimal expansion of 5% is 0.05. Multiplyin by 35 get us [tex]0.05\cdot35[/tex], so choice D works too.
Hope this helped!
Answer:
The answer is option D and BStep-by-step explanation:
To find the the value of the percentage of a number divide the percentage by 100 and multiply it by the number
So we have
5 percent of 35 is written as
[tex] \frac{5}{100} \times 35 \\ = \frac{1}{20} \times 35 \\ = \frac{7}{4} [/tex]
We have the answer as
1.75
From the options the one that has the same value as the above answer are
0.05 × 35 and 5/100 × 35

find the 40th term of an AP where 12th term is 45 and 17th term is 80.
Answer:
40th term = 241.
Step-by-step explanation:
17th term:
= a1 + 16d = 80
12th term
= a1 + 11d = 45 Subtracting the 2 equations:
5d = 80 - 45 = 35
d = 7
and a1 + 16(7) = 80
a1 = 80 -112 = -32.
Therefore the 40th term = -32 + 39*7
= 241.

cosθ=0.5 (to nearest degree)
Step-by-step explanation:
Hey, there!!
Given,
cos theta = 0.5
To convert it into angle, you have to take cos to right side making it (cos inverse).
Therefore, theta = cos inverse (0.5)
= 60°.

2z-1= -9+ z i need the answer RIGHT NOW
Answer:
z = -8
Step-by-step explanation:
I'm guessing you want to find out what z is equal to, so here you go.
2z - 1 = -9 + z
2z = -8 + z
z = -8
Answer:
z = -8
Step-by-step explanation:
let's simplify the equation by getting the like terms together.
2z-1 = -9+z
first get the z's on the same side:
2z-z-1 = -9
z-1 = 9
then the constants:
z = -9+1
z = -8
A Blue Viper can travel 18 2/5 miles on 4/5
tank of gas. A Red Rocket can travel 17 2/5 miles on 3/4 tank of gas. Which car can travel
further on one tank of gas?
Answer:
A Blue Viper
Step-by-step explanation:
A Blue Viper can travel 18 2/5 miles on 4/5 tank of gas.
It can travel on full tank:
(18 2/5)*1/5 + 18 2/5 = 92/5*1/5 + 92/5 = 92/5*6/5 = 552/25 = 22.08 milesA Red Rocket can travel 17 2/5 miles on 3/4 tank of gas.
It can travel on full tank:
(17 2/5)*1/4 + 17 2/5 = 87/5*1/4 + 87/5 = 87/5*5/4 = 87/4 = 21.75 milesA Blue Viper can travel further as:
22.08 > 21.75

Jason's monthly practice time on the piano is 35 hours. This month, he has practiced 8.5 hours in week 1, 12 hours in week 2, and 5.5 hours in week 3. How many more hours of practice time does Jason need to complete?
Given :
Monthly practice time , T=35 hours .
This month, he has practiced 8.5 hours in week 1, 12 hours in week 2, and 5.5 hours in week 3.
To Find :
Many more hours of practice time does Jason need to complete .
Solution :
Number of hours he practice in week 1 , [tex]t_1=8.5\ hours[/tex] .
Number of hours he practice in week 2 , [tex]t_2=12\ hours[/tex] .
Number of hours he practice in week 3 , [tex]t_3=5.5\ hours[/tex] .
Now , number of hours left is :
[tex]t=T-t_1-t_2-t_3\\\\t=35-(8.5+12+5.5)\ hours\\\\t=8\ hours[/tex]
Hence , this is the required solution .

A basketball player scored 351 points last year. If the player plays 18 games this year, how many points will he need to average per game to beat last year’s total?
Answer:
The answer is C in my opinion and it is one of confusing question i have ever seen
Step-by-step explanation:
If he scored 351 points last years and he plays 18 games this year and if we want to know the points that he need to beat last year score in thsi year we need to divide 351÷18=19.5 so he will need to have no morethan 20 points because 19.5 is also enough to get the score

Find m∠XYZ in the figure if ∠XYZ and ∠PQR are supplementary angles. please explain your answer Question 1 options: A) 83° B) 7° C) 173° D) 97°
Answer:
It's D) 97°
Step-by-step explanation:
Just stick this in ya brain
Supplementary angles => sum => 180
Answer:
D
Step-by-step explanation:
So, we know that ∠XYZ and ∠PQR are supplementary angles. This means that their total sum is 180 degrees. In an equation, this is:
[tex]\angle PQR+\angle XYZ=180[/tex]
Since we already know the measure of PQR, substitute 83 for PQR:
[tex]83+\angle XYZ=180[/tex]
Subtract 83 from both sides:
[tex](83+\angle XYZ)-83=(180)-83\\\angle XYZ=97\textdegree[/tex]
The answer is D

What is the solution set for 5x – 1 < 7x - 47
Answer:
x > 23
Step-by-step explanation:
5x – 1 < 7x - 47
Add 1 to -47, you get -46.
5x < 7x - 46
Subtract 7x from 5x.
-2x < -46
Multiply both sides to reverse the inequality.
2x > 46
Divide both sides by 2.
x > 23

On Friday there were 8 snowboarders for every 3 skiers at Slovak ski resort. On Saturday the ratio of the number of snowboarders to the number of skiers was 4:7 there were 168 snowboarders at the ski resort on Friday there were the same number of people at the ski resort on Saturday as there were on Friday how many more skiers were there than snowboarders at the ski resort on Saturday
Answer:
There are 46 more skiers than snowboarder
Step-by-step explanation:
Given
Ratio of Snowboarders to Skiers
On Friday:
[tex]Ratio = 8 : 3[/tex]
On Saturday:
[tex]Ratio = 4 : 7[/tex]
Population = 168
Required
Determine the difference in the number of skiers and snowboarders on Saturday
On Saturday, we have
[tex]Ratio = 4 : 7[/tex]
Calculate Total
[tex]Total = 4 + 7[/tex]
[tex]Total = 11[/tex]
Calculate the number of skiers
[tex]Skiers = \frac{7}{11} * 168[/tex]
[tex]Skiers = \frac{1176}{11}[/tex]
[tex]Skiers = 107[/tex] (Approximated)
Calculate the number of snowboarders
[tex]Snowboarders = \frac{4}{11} * 168[/tex]
[tex]Snowboarders = \frac{672}{11}[/tex]
[tex]Snowboarders = 61[/tex] (Approximated)
Calculate the difference
[tex]Difference = 107 - 61[/tex]
[tex]Difference = 46[/tex]
Hence, there are 46 more skiers than snowboarder

у=x+5 3x+y=25 substitution
Answer:
(5,10)
Step-by-step explanation:
So we have the system of equations:
[tex]y=x+5\\3x+y=25[/tex]
To solve, we can use substitution.
Substitute the first equation into the second:
[tex]3x+y=25\\3x+(x+5)=25[/tex]
Combine like terms:
[tex]4x+5=25[/tex]
Subtract 5:
[tex]4x=20[/tex]
Divide by 4:
[tex]x=5[/tex]
Now, substitute this into the first equation:
[tex]y=x+5\\y=5+5[/tex]
Add:
[tex]y=10[/tex]
So, our answer is (5,10)
And we are done :)
