the side length of a square measures 2 x+1 and the side lengths of a triangle are 2x, 2x, and 3x+10.The square and triangle have the same perimeter. Find the perimeter
Answer:
perimeter = 52
Step-by-step explanation:
side of square = 2x + 1
so first lets find the perimeter of squarep = 4 × s (side)
p = 4(2x +1)............. from the given
p = 8x + 4...... we will come back for this equation
side of trianles = 2x,2x,3x + 10
second lets find the perimeter of trianglep = s + s + s ( all the three sides)
p = 2x + 2x + 3x + 10
p = 7x + 10........we got another equation we will use it later
The question says the perimeter of square and the perimeter of triangle are equal so8x + 4(the perimeter of square we solved before) = 7x + 10(the perimeter of triangle we solved before)8x + 4 = 7x + 10
8x - 7x = 10 - 4
x = 6 ... now lets substitute x
8x + 4
8 × 6 +4
48 + 4
52
the same thing will happen if we substitute for the perimeter of triangle too.

what is 2/4 as a % plz hurry important
Answer: 50%
To convert fractions into a percentage you Divide the Numerator and Denominator.
2÷4=0.5
Since the result came out as a decimal we convert it to a percentage.
As you can see 5 is in the tenth place so that means 0.5 as a percent is 50%
A seat on a Ferris wheel is level with the center of the wheel.The diameter of the wheel is 200 feet. Suppose the wheel rotated 60°, causing the height of the seat to decrease. How much closer to the ground is the seat after the rotation
Answer: 86.6ft closer to the ground.
Step-by-step explanation:
The diameter of the wheel is 200ft
Then the radius, half of the diameter, is: r = 200ft/2 = 100ft.
Initially, the seat is at the same level that the center of the wheel.
And the distance between the center of the wheel and the bottom is the radius.
Then the initial position is at an angle of 0° from the x-axis. (where the (0,0) of this axis coincides with the center of the wheel=
Now, the wheel rotates 60°. (downwards, so we actually could use -60° measuring from the positive x-axis)
And thinking in this as a triangle rectangle, where the opposite angle is 60°, we can calculate the displacement in the vertical direction as:
y = sin(-60°)*R
y = sin(-60°)*100ft = -86.6ft
So the seat is 86.6ft closer to the ground.
The seat is [tex]86.6feet[/tex] closer to the ground
The seat will be closer by the height it drops when the Ferris wheel turns downwards by [tex]60^{\circ}[/tex].
The height, and the radius of the Ferris wheel form the opposite and the hypotenuse of a [tex]60^{\circ}[/tex] right-angled triangle. Since the diameter of the Ferris wheel is 200feet, the radius will be 100feet. So we have
[tex]sin60^{\circ}=\frac{opp}{hyp}=\frac{h}{100}\\\\h=100\times sin60^{\circ}\\=100\times 0.8660\\=86.6[/tex]
So the seat is [tex]86.6feet[/tex] closer to the ground

A commercial jetliner hits an air pocket and drops 264 feet. After climbing 151 feet, it drops another 103 feet. What is its overall vertical change?
Answer:
If we take the drops as negatives, and the climbs as positives (the answer will be the absolute value of these) we get:
-221 +174 -156.
When you add these together, you get -203. So the overall vertical change is the absolute value of this, or 203 ft.

Answer:
[tex]25\frac{1}{4}[/tex] feet
Step-by-step explanation:
Given
[tex]Maddy = 67\frac{3}{4}[/tex] above Jasmin
[tex]Jasmin = 42\frac{1}{2}[/tex] below Quinn
Required
Determine Maddy's position relative to Quinn's
From the given parameter, one can easily deduce that Quinn is in between Maddy and Jasmin (See attachment)
Using the attachment as a point of reference;
[tex]z = 67\frac{3}{4}[/tex]
[tex]x = 42\frac{1}{2}[/tex]
The relationship between x, y and z is
[tex]z = y + x[/tex]
Make y the subject of formula
[tex]y = z - x[/tex]
Substitute the values of z and x
[tex]y = 67\frac{3}{4} - 42\frac{1}{2}[/tex]
Convert to improper fractions
[tex]y = \frac{271}{4} - \frac{85}{2}[/tex]
Take LCM
[tex]y = \frac{271 - 170}{4}[/tex]
[tex]y = \frac{101}{4}[/tex]
[tex]y = 25\frac{1}{4}[/tex]
Hence; Maddy's position relative to Quinn's is [tex]25\frac{1}{4}[/tex] feet

The 100 residents are asked if they like to watch basketball and or football. The results are that 98 like to watch basketball, 12 like to watch football, and 2 dislike both. How many like to watch football?
Answer:
12 people like to watch football
Step-by-step explanation:
The results are that 98 like to watch basketball, 12 like to watch football, and 2 dislike both.
Total number of residents = 100
Basketball (B) = 98
Football(F) = 12
Number of residents that like basketball and football = ( B ∩ F)
2 dislike both
n ( B ∪ F) - People that dislike it = n(B) + n ( F ) - n ( B ∩ F)
100 - 2 = 98 + 12 - n ( B ∩ F)
98 = 110 - n ( B ∩ F)
n ( B ∩ F) = 110 - 98
= 12
Therefore, 12 people like both Football and Basketball
How many like to watch football?
From the above question, we can see that the total number of people that like to watch football = 12 people

After school activities activity number student Spanish club 19 baseball 24 drama 15 homework help 17 soccer 20 which ratio compares the numbers of students to Spanish clubs in the the total number of students
Answer:
19:95
Step-by-step explanation:
Spanish club have 19 students
Baseball have 24 students
Drama have 15 students
Home work help have 17 students
Soccer have 20 students
The first step is to calculate the total number of students
= 19 + 24 + 15 + 17 + 20
= 95 students
Since the Spanish club have 19 students and the total number of students is 95 then, the ratio which compares the number of students in Spanish club to the total number of students is 19:95
Answer: 19:95, 19 to 95, or 19/95. They all equal the same so it depends which one is your option. ORDER OF RATIO MATTERS!!
Explanation: The students in the Spanish club are 19 and to find the total number of students, you add 19 + 24 + 15 + 17 + 20 which equals 95. Then you put 19 first then 95. This is because it asked to compare the number of students in the Spanish clubs (so this is first) to the the total number of students (so this is second).
When a car's brakes are applied, it travels 7 feet less in each second than the previous second until it comes to a complete stop. A car goes 28 feet in the first second after the brakes are applied. How many feet does the car travel from the time the brakes are applied to the time the car stops?
Answer:
70feet
Step-by-step explanation:
during the
1st sec it travels 28 ft
2nd sec =28-7=21ft
3rd sec= 21-7=14ft
4th sec= 14-7= 7ft
last sec=7-7=0ft, at this point the car stops.
so altogether it travels 28+21+14+7+0= 70 feet
Which equation shows the inverse property of multiplication? 4 + (-4) = 0 -8 + (-3) = -3 + (-8) 2 times one-half = 1 Eight-fifths + 0 = Eight-fifths
Answer:
2 times one-half = 1
Step-by-step explanation:
In order to show a property of multiplication, the equation must involve multiplication. There is only one choice that does.
2 times one-half = 1
__
The multiplicative inverse of a number, multiplied by the number, results in 1, the multiplicative identity element.
Equation C,2 times one-half = 1 shows the inverse property of multiplication. Option C is correct.
What is multiplicative inverse?A multiplicative inverse is a number whose value is equal to 1 when multiplied by the original number.
The left-hand side of the equation is;
LHS = 2 times one-half
LHS = 2×(1/2)
LHS = 2
The right-hand side of the equation is;
RHS =1
If both LHS and RHS are equal and the RHS value is equal to 1 the RHS is the multiplicative inverse of LHS.
Equation C,2 times one-half = 1 shows the inverse property of multiplication.
Hence, option C is correct.
