Answer:
755 gram lighter
Step-by-step explanation:
Convert 1.1kg into gram by multiplying it with 1000
1.1 x 1000= 1100 and we take this amount and subtract it with 345g
1100-345= 755g

5. A w-foot wide path is to be built around a rectangular space that is 80
feet by 50 feet. Write and simplify an expression for the total area.
To find the area of the path, we'll need to find the area of the space with the path and subtract the area of the inner space.
Total area: (80 + w)(50 + w)
Inner area: 80 x 50
Area of the path: (80 + w)(50 + w) - (80 x 50)
(4000 + 80w + 50w + w^2) - (4000)
4000 + 130w + w^2 - 4000
w^2 + 130w
w(w + 130)
Expression for the total area: (80 + w)(50 + w)
Expression for the area of the path: w(w + 130)

In an isosceles triangle, the length of the base is half of the length of a leg. The perimeter of this triangle is 50 cm. Find the lengths of all sides.
Answer:
10 cm, 20 cm, 20 cmStep-by-step explanation:
Let the base is x, then the legs are 2x each.
The perimeter is:
x + 2x*2 = 505x = 50x = 10The base is 10 cm and legs are 20 cm each.

Answer:
It should be c
Step-by-step explanation:
Your formula is
Number of color ball/total ball
so 8/20 x 7/19 x 3/18 then convert to fraction
The probability the first ball is red is 0.4 or 8/20 or 2/5
The probability the next is blue is 7/19
The probability of the next being white is 6/18 or 1/3.
Multiply them together because these are independent events that must all occur and we get 2*7*1= 14 as the numerator
5*19*3=285 for a total probability of 14/285.

What is the result when the number 24 is increased by 6%?
Answer:
24 increased by 6% = 25.44
Step-by-step explanation:
Introduction. Percent, p%
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100.
6% = 6/100 = 6 ÷ 100 = 0.06.
100% = 100/100 = 100 ÷ 100 = 1.
ncrease the number by 6% of its value.
Percentage increase = 6% × 24
New value = 24 + Percentage increase
Calculate the New Value
New value =
24 + Percentage increase =
24 + (6% × 24) =
24 + 6% × 24 =
(1 + 6%) × 24 =
(100% + 6%) × 24 =
106% × 24 =
106 ÷ 100 × 24 =
106 × 24 ÷ 100 =
2,544 ÷ 100 =
25.44
Calculate absolute change (actual difference)
Absolute change (actual difference) =
New value - 24 =
25.44 - 24 =
1.44
Proof.
Calculate percentage increase...
... And see if we get as a result
the absolute change (actual difference).
Percentage increase =
6% × 24 =
6 ÷ 100 × 24 =
6 × 24 ÷ 100 =
144 ÷ 100 =
1.44
So we have proven that the calculations are correct.
For positive numbers
Absolute change (actual difference) =
Percentage increase
Answer:
24 increased by 6% = 25.44
Absolute change (actual difference):
25.44 - 24 = 1.44
Answer:
24,06
Step-by-step explanation:
[tex] \sf 24 + 6 \%[/tex]
[tex] \sf = 24 + \frac{6}{100} [/tex]

HIGHWAYS Interstate 90 is the longest interstate highway in the United States, connecting the cities of Seattle, Washington, and Boston,
Massachusetts. The interstate is 4,987,000 meters in length. If 1 mile = 1.609 kilometers, how many miles long is Interstate 90?
Oa 3.099,441 mi
Ob. 3099 mi
Oc. 8,024,083 mi
O d. 8024 mi
=============================================================
Explanation:
4,987,000 meters = 4,987 kilometers
Divide by 1000 to go from meters to kilometers. This is because 1 km = 1000 m. Or in short, we just chop off those last three zeros at the end.
Also, because 1 mile = 1.609 km (approximate), this means we divide by 1.609 when converting from km to miles
So,
4,987 km = 4987/(1.609) = 3,099.4406 miles approximately
This rounds to 3099 miles
----------------
You can optionally show your work like this:
[tex]4,987,000 \text{ m} * \frac{1 \text{ km}}{1000 \text{ m}}*\frac{1 \text{ mi}}{1.609 \text{ km}}\\\\ = \frac{4,987,000*1*1}{1000*1.609} \text{ mi} \\\\\approx 3099.4406 \text{ mi}\\\\ \approx \textbf{3099 mi}[/tex]
Notice that the "km" and "m" units cancel out when going from the first step to the second step. All that's left is the "mile" unit.
solve for y 1/3x+2y=8
1. Simplify [tex]\frac{1}{3} x[/tex] to [tex]\frac{x}{3}[/tex]
[tex]\frac{x}{3} +2y=8[/tex]
2. Subtract [tex]\frac{x}{3}[/tex] from both sides
[tex]2y=8-\frac{x}{3}[/tex]
3. Divide both sides by 2
[tex]y=\frac{8-\frac{x}{3} }{2}[/tex]
4. Simplify [tex]\frac{8-\frac{x}{3} }{2}[/tex] to [tex]\frac{8}{2}[/tex] - x/3/2
y=8/2-x/3/2
5. Simplify 8/2 to 4
y=4-x/3/2
6. Simplify x/3/2 to x/3x2
y=4-x/3x2
7. Simplify 3x2 to 6

Given the vertex ( 4, 6 )and the point(1, -3), write the vertex form equation of the quadratic
function.
Answer:
[tex]\displaystyle f(x) = -(x-4)^2 + 6[/tex]
Step-by-step explanation:
A given quadratic has its vertex at (4, 6) and the point (1, -3). We want to write the equation in vertex form of the quadratic.
Recall that vertex form is given by:
[tex]\displaystyle f(x) = a(x-h) ^2 + k[/tex]
Where (h, k) is the vertex and a is the leading coefficient.
Since our vertex is at (4, 6), h = 4 and k = 6:
[tex]\displaystyle f(x) = a(x - 4)^2 + 6[/tex]
To determine the leading coefficient, since we are given that (1, -3) is a point on the parabola, when x = 1, y = -3. Substitute and solve for a:
[tex]\displaystyle \begin{aligned} (-3) & = a((1)-4)^2 + 6 \\ \\ -3 & = a(-3)^2 + 6 \\ \\ 9a & = -9 \\ \\ a & = -1 \end{aligned}[/tex]
Hence, the leading coefficient a is -1.
Then our equation in vertex form is:
[tex]\displaystyle f(x) = -(x-4)^2 + 6[/tex]

Here's the solution :
1. The given figure is of a Rectangle, and we know that diagnonals of a Rectangle bisects each other.
so, PR = 2 × PT

PR = QS = 20 units2. let's take the length of PQ = x and QR = y

Answer:

[tex]5(3y-1)+10y=20[/tex]
Now solve for y.
[tex]y=1[/tex]

Nick jumps off a cliff. It takes him 2.2 s to hit the water below. What is the height of the cliff? g=9.8 m/s2
Answer:
9.8 x 2.2 = 21.56 m
distance = time x speed
speed = distance ÷ time
Step-by-step explanation:
The highest point he reached occurred at the vertex, which is at t = -b/2a = 2.2 second. Plugging in t = 2.2
9.8 x 2.2 = 21.56ft
Higher cliffs don't accelerate your fall -- acceleration is constant during free fall. The pull of gravity decreases infinitesimally at higher elevations, but it pulls you with an equal force from the first second of your jump until you decelerate when you hit the water.
Miguel Ponce has P1,500.00 cash. If he bought a pair of shoes for P1,325.00, what is the percent of the remaining cash he has left?
Answer:
Step-by-step explanation:
Cash remaining=P1, 500.00-P1,325.00
=P175
Percent of the remaining cash= Cash Remaining × 100
Cash he originally had
= P175 × 100
P1 500
=11[tex]\frac{2}{3}[/tex] %or 11.6666666% or 11.67% when rounded to two decimal places.
A percentage is a way to describe a part of a whole. The percent of the remaining cash he has left is 11.667%.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Value of the Remaing Cash = P1,500.00 - P1,325.00
= P175.00
Now, the percent of the remaining cash he has left can be written as,
Percentage of remaining cash = (Remaining cash/ Total cash) × 100%
= (P175.00 / P1,500.00) × 100%
= 0.011667 × 100%
= 11.667%
Hence, the percent of the remaining cash he has left is 11.667%.
