Diego is 165 cm tall. Andre is 1.7 m tall.
1. Who is taller, Diego or Andre?
2. Explain your reasoning.
Answer:
Andre
Step-by-step explanation:
If a meter is made up of 100 cm then divide 165 by 100. Compare 1.65 meters to 1.7 meters. 1.65 m < 1.7 m

Solve these simultaneous equations:
3. 5x – 3y = 15 4x 3y = 6
2x + 5y = 26 4x + 3y = 24
3x + 3y = 39 2x - 3y = - 2
Answer:
1) We have the system:
5*x - 3*y = 15
4*x + 3*y = 6
To solve this, we first need to isolate one of the variables in one of the equations, let's isolate x in the first equation:
x = 15/5 + (3/5)*y = 3 + (3/5)*y
Now we can replace this in the other equation to get:
4*( 3 + (3/5)*y) + 3*y = 6
and solve this for y.
12 + (12/5)*y + 3*y = 6
(12/5 + 3)*y = 6 - 12 = -6
(12/5 + 15/5)*y = -6
(27/5)*y = -6
y = -6*(5/27) = 1.11
Now we can replace this in the equation:
x = 3 + (3/5)*y
To get the value of x.
x = 3 + (3/5)*1.11 = 3.67
Then the solution of this system is the point (3.67, 1.11)
2) Now we have the system:
2*x + 5*y = 26
4*x + 3*y = 24
The solution method is the same as before:
x = 26/2 - (5/2)*y = 13 - (5/2)*y
Now we replace this in the other equation:
4*( 13 - (5/2)*y) + 3*y = 24
52 - 10*y + 3*y = 24
52 - 7*y = 24
52 - 24 = 7*y
28 = 7*y
28/7 = y
4 = y
now we replace this in the equatio:
x = 13 - (5/2)*y
x = 13 - (5/2)*4 = 13 - 10 = 3
The solution of this sytem is (3, 4)
3) Now we have the system:
3*x + 3*y = 39
2*x - 3*y = -2
first we isolate x in the first equation:
x = 39/3 - 3*y/3 = 13 - y
Now we can replace this in the other equation:
2*(13 - y) - 3*y = -2
26 - 2*y - 3*y = -2
26 - 5*y = -2
26 + 2 = 5*y
28 = 5*y
28/5 = y = 5.6
Now we can replace this in the equation:
x = 13 - y
To get the x-value
x = 13 - 5.6 = 7.4
Then the solution for this system is (7.4, 5.6)
Write down the 3rd term in the sequence given by: T(n) = 2n² + n
Answer:
T(3) = 21
Step-by-step explanation:
To find the third term, substitute n = 3 into T(n) , that is
T(3) = 2(3)² + 3 = 2(9) + 3 = 18 + 3 = 21

What is the equation of the line with a slope of 2 through (-4, 6) in point-slope form?
O y = 2x + 14
Oy-6 = 2 (x +4)
Oy= 2x – 14
Oy+6 = 2 (x – 4)
Answer:
y - 6 = 2(x + 4)
Step-by-step explanation:
Point slope form is y - [tex]y_{1}[/tex] = m (x - [tex]x_{1}[/tex]).
[tex]x_{1}[/tex] and [tex]y_{1}[/tex] are the points that they give you in the problem, which is (-4, 6), and m is the slope, which is 2.
When you plug everything in, you should get
y - 6 = 2(x + 4).

Who can help me with these two?!? and can show work plz
Answer:
(4, 2 ) and (5, - 4 )
Step-by-step explanation:
(3)
6x + 2y = 28 → (1)
x = 2y → (2)
Substitute x = 2y into (1)
6(2y) + 2y = 28
12y + 2y = 28
14y = 28 ( divide both sides by 14 )
y = 2
Substitute y = 2 into (2) for corresponding value of x
x = 2(2) = 4
solution is (4, 2 )
(4)
x + y = 1 → (1)
2x + y = 6 → (2)
Rearrange (2) expressing y in terms of x by subtracting 2x from both sides
y = 6 - 2x → (3)
Substitute y = 6 - 2x into (1)
x + 6 - 2x = 1
- x + 6 = 1 ( subtract 6 from both sides )
- x = - 5 ( multiply both sides by - 1 )
x = 5
Substitute x = 5 into (3) for corresponding value of y
y = 6 - 2(5) = 6 - 10 = - 4
solution is (5, - 4 )

4. I dug the flowerbeds with a spade.
5. The mountaineer reached the peak with great difficulty.
Explanation:
Prepositions are the words that tell us or gives information about the location, place, time, or the relation of the noun or pronoun with the other words in the sentence. In short, they tell us where, when, or how something happens.
The prepositions in the given sentences are underlined as follows-
1. The bus shuttles between Delhi and Gurgaon.
2. The children ran across the bridge.
3. Towards evening, you can hear the frogs croak.

There are 225 wolves in the state park. The population is increasing at a rate of 15% per year. Make a prediction for how long it will take the population to reach 500.
Answer:
Step-by-step explanation:
F=I(1+r)^t
500=225(1.15^t)
t=ln(500/225)/(ln1.15)
t=5.713 years
Taxis usually charge a fee on top of the per-mile charge. In this case, the taxi charges $3 as a set fee and $0.80 per mile traveled. The function y=0.8x+3 is used to represent the total cost of a ride.
Answer:
$12.3
Step-by-step explanation:
Given data
We are given that the function for the charge is expressed as
y=0.8x+3
Where y is the total cost for a ride
X is the distance of the ride
Say x= 12 miles
Hence the total cost of the ride is
Y= 0.8*12+3
Y= 9.6+3
Y= $12.3
Hence a 12 miles Distance will cost $12.3
Answer: his answer is right
Step-by-step explanation:
Michael takes a sip of water every 20 minutes while playing soccer. He took his first sip at 3:05. When did he take his sixth sip?
Answer:
Michael took his 6th sip at 4 : 05
Step-by-step explanation:
Duration in which Michael takes a sip of water = 20 minutes
Therefore, he will take his sixth sip after (20 × 6) = 120 minutes Or after 2 hours
If he takes first sip of water at 3 : 05
Then he will take his sixth sip at ( 3 : 05 + 2 : 00)
Time at his sixth sip = 5 : 05

What is the value of the digit 6 in this number? Write your answer in number form.
647,013,020
Answer:
6= six hundred million.Use completing the square to solve the equation x2 - 10x = -8.
Which equation is used in the process?
x 2 - 10x + 25 = 17
x 2 - 10x + 25 = -8
x 2 - 10x - 25 = -33
Answer:
x^2 - 10x + 25 = 17
Step-by-step explanation:
x^2 - 10x = - 8
Now x^2 - 10x = (x - 5)^2 - 25, so
(x - 5)^2 - 25 = -8
(x - 5)^2 = -8 + 25
x^2 - 10x + 25 = 17..

There are 60 children in a club. In the club, the ratio of the number of girls to the number of boys is 3:1 3/5 of the girls play a musical instrument. 4/5 of the boys play a musical instrument. What fraction of the 60 children play a musical instrument?
Answer:
3/20
Step-by-step explanation:
There are 60 children in a club. In the club, the ratio of the number of girls to the number of boys is 3:1
Step 1
We find the number of girls and boys
The ratio is given as:
Girls : Boys
3:1
The sum of Proportion = 3 + 1 = 4
The number of girls
= 3/4 × 60 children
= 45 girls
The Number of boys
= 1/4 × 60 children
= 15 boys
Step 2
From the question, we are told:
3/5 of the girls play a musical instrument.
The number of girls that play Instruments is calculated as:
3/5 × Number of girls
= 3/5 × 45 girls
= 27 girls
4/5 of the boys play a musical
instrument.
The number of boys that play Instruments is calculated as:
4/5 × Number of boys
= 4/5 × 15 boys
= 12 boys
Step 3
The fraction of the 60 children that play a musical instrument is calculated as:
Sum of boys and girls that play a musical instrument/ 60 children
= 27 girls + 12 boys/60
= 39/60
= 3/20
The fraction of the 60 children that play a musical instrument is 3/20
