Answer:
A)
Step-by-step explanation:
The set of rational numbers is closed for all the four operations‚ so x+y‚ x-y‚ x*y and x/y are rational too a rational number can be expressed as a fraction of two integers. so‚ x can be expressed as a/b and y as c/d.
-2(x+1)(x-2) what is the y-intercept?
Answer:
The y-intercept is at 4.
Step-by-step explanation:
When trying to find the y-intercept, you want to substitute your x's with 0 as x must equal 0 for your y-intercept. This gives you -2(0+1)(0-2). From here, you want to simplify your parenthesis equations.-2(1)(-2) Then you want to solve which gives you 4.
Please please help ASAP! Classify each angle!
Answer:
Acute Angles: ∠TLS, ∠SLT, ∠ULR Right Angles: --------- Obtuse Angles: ∠RLT, ∠SLU, ∠ULS, Straight Angles: ∠RLS, ∠TLU Not angles: ∠TRLStep-by-step explanation:
The lines intersect at point L, so all angles have a vertex (middle letter) L so there is no angle TRL
Straight angle is a line with dot-vertex, so the straight angles are ∠RLS and ∠TLU.
∠TLS is less than 90° then it is acute angle (∠SLT is the same angle). ∠ULR is vertex angle to ∠TLS, so it's also acute angle.
Two angles adding to straight angle mean that they are both right angles or one is acute and the second is obtuse. ∠TLS is acute so ∠RLT is obtuse (they adding to ∠RLS) and ∠SLU is obtuse (they adding to ∠TLU). ∠ULS is the same angle as ∠SLU.
Find the value of x and then find the length of RT
RT =
X=
Answer:
x = 5, RT = 18
Step-by-step explanation:
[tex]\triangle MNL \sim \triangle SRT... (given) \\
\therefore \frac{MN}{SR} = \frac{NL}{RT}.. (c.s.s.t)\\ \\
\therefore \frac{84}{24} = \frac{63}{3x+3}\\ \\
\therefore \frac{7}{2} = \frac{63}{3x+3}\\ \\
\therefore 3x+3 = \frac{63\times 2}{7}\\ \\
\therefore 3x + 3 = 9\times 2\\
\therefore 3x + 3 = 18\\
\therefore 3x = 18 - 3\\
\therefore 3x=15\\
\therefore x = \frac{15}{3}\\
\huge \red {\boxed {\therefore x = 5}} \\ \\
\because RT = 3x + 3\\
\therefore RT = 3\times 5+ 3\\
\therefore RT = 15+ 3\\
\huge \orange {\boxed {\therefore RT = 18}} [/tex]
Is the line passing through the points (−4,5)
and (1,10)
parallel to the line passing through the points (−18,−6)
and (−8,4)
?
A
No, because the slopes of the lines are the same, but the y-intercepts are different.
B
No, because the slopes of the lines are different.
C
Yes, because the slopes of the lines are the same, but the y-intercepts are different.
D
Yes, because the slopes of the lines are different.
if a cheetah runs 1 mile a second how many miles does he run in one minute
Answer:
The answer would be 60 miles.
Step-by-step explanation:
There are 60 second in a minute. If a cheetah runs 1 mile a second, the equation would be 1 mile X 60 seconds. 1x60=60.
Hope this helps!
Solve for k.
6 + -4k = 18
k=
k=-3
6*(-4k)=18
subtract 6 from both sides
-4k=12
divide by -4 on both sides
k=-3
Answer:
[tex] \sf \: k = - 3[/tex]
Step-by-step explanation:
Now we have to,
→ Find the required value of k.
The equation is,
→ 6 + (-4k) = 18
Then the value of k will be,
→ 6 + (-4k) = 18
→ 6 - 4k = 18
→ -4k = 18 - 6
→ -4k = 12
→ k = 12 ÷ (-4)
→ [ k = -3 ]
Hence, the value of k is -3.

Pythagorean theorem
Answer:
8.7
Step-by-step explanation:
hypotenuse= 14 =c
a=11
b=x
a²+b²=c²
b²=c²-a²
b²=14²-11²
b²= 196-121
b²=75
b=√75=5√3=8.7 rounded to the nearest tenth
Final Answer:
x = 8.66
Step-by-step explanation:
formula: [tex]b=\sqrt{c^2-a^2}[/tex]
a = 11
b = x
c = 14
[tex]b=\sqrt{14^2-11^2}[/tex]
[tex]b=\sqrt{196-121}[/tex]
[tex]b=\sqrt{75}[/tex]
b = 8.66025
x = 8.66
rounded off to the nearest hundredths: 8.66

Answer:
You could solve this by taking the y value and adding it to the multiplied rate.
For example: For Jill's 6 year mark, the equation would be 11(6) + 15.

A plane traveled 360 miles each way to Athens and back. The trip there was with the wind. It took 3 hours. The trip back was into the wind. The trip back took 6 hours. Find the speed of the plane in still air and the speed of the wind.
Answer:
S=32.5
W=97.5
Step-by-step explanation:
S=speed of plane in still air
W=speed of wind
-----------------------------------------
3(S+W)=130
6(S-W)=130
-----------------------------------------
S+W=43.33333...
S-W=21.66666...
2S=64.999...
S=32.5(simplified)
-----------------------------------------
32.5+W=130
W=97.5

The diameter of a cylindrical construction pipe is 4 ft. If the pipe is 20 ft long, what is its volume?
Figure B is a scaled copy of Figure A.
Figure A
Figure B
What is the scale factor from Figure A to Figure B?
Greetings from Brasil...
Comparing the distances AB and A'B ', we notice that AB = 3 and A'B' '= 9.
We can say that:
AB · X = A'B'
3 · X = 9
3X = 9
X = 9 ÷ 3
X = 3
Thus, figure B is 3x larger than figure A
scale factor = 3x larger
Answer:
x=3
Step-by-step explanation:
AB = 3 and A'B' '= 9.

-Oxygenated blood is pumped to the rest of the body via the aorta.
-Deoxygenated blood (blood that needs oxygen) coming from the body.
-Then is pumped to the right ventricle.
-Then is pumped to the lunges to get oxygen via the pulmonary artery,
-Oxygenated blood from the lunges flows into the left atrium via the pulmonary vein.
-Flows into the right atrium.
-Then is pumped into the left ventricle.

a)In the scale drawing, the height of the houses is 8 inches. What is the height of the real house?
b)The length of the real house is 35 feet. What is the length of the house in the scale drawing.
Answer:
a) 40 ft
b) 7 inches
Step-by-step explanation:
A) Multiply the given scale factor by 8 to get 8 inches:
1 in : 5 ft ⇒ 8 in : 40 ft
The real house is 40 ft high.
__
B) If you like, you can write the proportion ...
dwg / (35 ft) = 1 in / (5 ft)
Multiplying by 35 ft gives ...
dwg = (1 in)×(35 ft)/(5 ft) = 7 in
The length of the house in the scale drawing is 7 inches.
Answer:a=40
b=7

Is the identity property the same as the simplify property?
Answer:
La propiedad de la identidad de 1 dice que cualquier número multiplicado por 1 mantiene su identidad. En otras palabras, cualquier número multiplicado por 1 permanece igual. El número permanece igual porque multiplicar por 1 significa que tenemos 1 copia del número. Por ejemplo, 32x1=32.

In the diagram, line segment CD is the perpendicular bisector of line segment AB, and E is a point not on either line that is on the same side of segment CD as point A.
Is point E closer to point A, closer to point B, or the same distance from both points? Explain how you know.
Answer:
E would be closer to A
explanation:
if they were the same distance from both A and E it would be a point on the line CD, and if it was closer to E it would be on the other side of line CD.

Answer:
Each side is 4 cm.
Step-by-step explanation:
We need to try to express the perimeter of the figure in terms of "square sides". Basically, we're going to count how many square sides the perimeter is.
Starting from the top, the very top is 1 side.
Moving down to the right, we have another side.
Then half a side as we go to the right edge.
The right edge is 1 full side.
Another half side, going left.
Going down, we have 1 full side.
The other side is mirrored, meaning we just have to double this to get the full figure's perimiter.
Counting up our sides (we'll call one side [tex]s[/tex] ), we have:
1s + 1s + 0.5s + 1s + 0.5s + 1s = 4s + 0.5s + 0.5s = 5s
Doubling it:
5s * 2 = 10s
The whole perimiter is 8 square sides. Since we know the perimeter is 40 cm, we can find the length of one side by solving this equation:
10s = 40
Dividing both sides by 10:
s = 40/10 = 4
Answer: Each side is 4 cm.

A shirt is on sale for 40% off. The sale price is $12. How much was the original price? *
Answer:
$20
Step-by-step explanation:
Let the variable x in this equation represents the original price of the shirt:
100% - 40% = 60%
60% of x = $12
0.6x = $12
x = $12/0.6
x = $20
