Answer:
6.4 feet
12.8 feet
14.8 feet
Step-by-step explanation:
let x = length of 1st side
let 2x = length of 2nd side
let 2x + 2 = length of 3rd side
add them all together and set sum equal to 34
x + 2x + 2x + 2 = 34
5x + 2 = 34
5x = 32
x = 6.4, which is 1st side
2x = 12.8, which is 2nd side
2x + 2 = 14.8, which is 3rd side

The value of expression at x = 3 is,
⇒ 30
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ 6² + x - x²
Now, We can simplify as;
⇒ 6² + x - x²
⇒ 36 + x - x²
Put x = 3;
⇒ 36 + 3 - 3²
⇒ 36 + 3 - 9
⇒ 36 - 6
⇒ 30
Thus, The value of expression at x = 3 is,
⇒ 30

1.3.PS-44 Question Help A housekeeper had 2 3 of a spray bottle of a cleaning solution. She used 1 4 of the solution in a day. How much of the bottle did she use?
Answer:
[tex]\bold{\frac{1}{6}}[/tex] of the bottle was used
Step-by-step explanation:
Amount of cleaning solution present in spray bottle = [tex]\frac{2}3[/tex] of the bottle
Amount of cleaning solution present in the spray bottle used = [tex]\frac{1}4[/tex] of the cleaning solution present initially
To find:
How much of the bottle was used?
Solution:
Here, we need to find how much amount of the cleaning solution spray was used from the complete bottle.
Amount of spray used = [tex]\frac{1}{4}\times \frac{2}{3}[/tex] of the cleaning solution = [tex]\bold{\frac{1}{6}}[/tex] of the cleaning solution.
Therefore, the answer is:
[tex]\bold{\frac{1}{6}}[/tex] of the bottle was used

Find the equation of the line passing through point (4,2) and perpendicular to AB
Answer:
a. -⅓
b. 3
c. y = 3x - 10
Step-by-step explanation:
a. Gradient of line AB:
A(1, 3), B(7, 1)
[tex] Gradient = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 - 3}{7 - 1} = \frac{-2}{6} = -\frac{1}{3} [/tex]
Gradient (m) = -⅓
b. The of the line that is perpendicular to line AB would be the negative reciprocal of the gradient of line AB.
Thus, the negative reciprocal of -⅓ = 3
Gradient of the line perpendicular to line AB = 3
c. Equation of the line that passes through (4, 2) and is perpendicular to line AB:
We can write the equation using the point-slope form equation, y - b = m(x - a), where,
(a, b) represents a point on the line, and,
m = gradient/slope
We know that the gradient/slope (m) = 3
Also, a point, (a, b) = (4, 2).
Therefore, substitute a = 4, b = 2, and m = 3 into y - b = m(x - a)
Thus:
y - 2 = 3(x - 4)
y - 2 = 3x - 12
Add 2 to both sides
y = 3x - 12 + 2
y = 3x - 10

Which choice is equivalent to the expression below?
2^7.19
Answer:
B
Step-by-step explanation:

In exponent multiplication, if bases are same, add the powers(exponents).
Write 7.19 in expanded form: 7.19 = 7 + 0.1 + 0.09. Now apply the exponent rule.
[tex]2^{7.19}=2^{7+0.1+0.09}\\\\=2^{7}*2^{0.1}*2^{0.09}\\\\= 2^{7}*2^{\frac{1}{10}}*2^{\frac{9}{100}}[/tex]

Answer: y > -1.5 which is the same as y > -3/2
==========================================================
Explanation:
As x goes off to negative infinity, the term 3^x gets closer to 0.
So the expression 0.5*(3^x - 3) approaches 0.5*(0-3) = 0.5*(-3) = -1.5 = -3/2
The y value will never actually get to -1.5 because 3^x never actually reaches 0. It only gets closer and closer.
So the range is the set of possible y outputs such that y > -1.5 or y > -3/2
This means the horizontal asymptote is y = -3/2 or y = -1.5 which is the horizontal "electric fence" of sorts that the function curve gets closer to, but never touches.

Answer:
I hope this makes sense, sorry for the lack of proofs.
Step-by-step explanation:
It is given that S is the midpoint of line QT. The definition of a midpoint is that it bisects the line it is on. So, line QS and line TS are congruent, or the same.
Now, we also know that line QR and line TU are parallel. Because they are parallel, it means that they form congruent corners with lines QS and TS..I think the proof here is "angles opposite to congruent sides are congruent in a triangle." But I'm not sure if this is right. Anyways, this means angles RQS and UTS are congruent.
There's also some proof that when two lines cross, the opposite angles are congruent. This means that angles TSU and QSR are congruent.
Therefore, by ASA (angle-side-angle) ΔQRS ≅ ΔTUS.

Driver’s Delight is considering building a new track. They have a circular space with a diameter of 150 feet. Compute the circumference of the circular space.
Tameka wants to build a circular go-cart track in her backyard. a. If she wants the track to have a circumference of 150 feet, what does the radius of the track need to be? b. If she wants the track to have a circumference of 200 feet, what does the radius of the track need to be? c. If she wants the track to have a circumference of 400 feet, what does the diameter of the track need to be?
the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.
a. The circumference of Track 1 is 376.8 feet.
b. The circumference of Track 2 is 533.8 feet.
c. . The circumference of Track 3 is 690.8 feet.
The circular space Driver’s Delight has of 150 feet radius will have a circumference of 471 feet.
What is circumference?The circumference is the distance around the circle and he formula to calculate is 2πr, where r is the radius.
Driver’s Delight has 3 circular tracks for go-carting.
Track 1 has a radius of 60 feet therefore the circumference of this circular track will be,
Track₁ circumference = (2πr).
= (2×3.14×60) feet.
= 376.8 feet.
Track 2 has a radius of 85 feet therefore the circumference of this circular track will be,
Track₂ circumference = (2πr).
= (2×3.14×85) feet.
= 533.8 feet.
Track 3 has a radius of 110 feet therefore the circumference of this track will be,
Track₃ circumference = (2πr).
= (2×3.14×110) feet.
= 690.8 feet.
They also have a circular space of 150 feet there the circumference of this circular space will also be (2πr). And we know Diameter = Twice of radius.
So, we just have to multiply the diameter by π which has an approximate value of 3.14.
So, the circumference of this circular space is
= 150×π feet.
= 150×3.14 feet.
= 471 feet.

3 Dave can drive from Abdet to Bentall by two routes. The old route goes in roughly a straight line while the new faster route is 26% longer. Dave's average speed on the new faster route is 40% higher than his average speed on the old route. (a) By what percentage is Dave's journey time reduced by taking the new route compared to the old? [2]
Answer:
10 % of the total time will be saved on the new route with the new speed.
Step-by-step explanation:
Let x miles be the old route. Then the new route would be 1.26 x miles
Let y be the speed on the old route . Then the speed on the new route would be 1.4 y .
And let t be the time on the old route
Speed = Distance / Time
or
Time = Distance / Speed
t= x/y
Time for the new route = 1.26x/ 1.4y= 0.9 t
0.9 t means 90% of the old time will be required to cover 1.26x miles with 1.4 y speed.
And 10 % of the total time will be saved on the new route with the new speed.
What is the slope of y=-x+7
Answer:
-1
Step-by-step explanation:
This is the slope because x is the slope, and if there is no number in front of x then x is 1. There is also a negative in front of x which means the answer is -1.
The slope of the equation y = -x + 7 equals -1.
