6.4 ÷ 1.6 of 5 + 1.3 × 3.1 - 0.07
Answer: 23.96
first you gotta put in the parenthese in. (6.4/1.6)x 5+( 1.3x3.1)-0.07.
second: do the Equation in the parentheses.
6.4/1.6=4
1.3x3.1=4.03
4x5=20
20+4.03=24.03
24.03-0.07=23.96 final answer
Hope this helps!!
A car wheel has a diameter of 27.1". How far will the car go when the wheels rotate 100 times?
Answer:
135.5"
Step-by-step explanation:
Answer:
8509.4
Step-by-step explanation:
The diameter has already been displayed so what I could simply do is solve the equation simply by using the formula for circumference using diameter (C=3.14 x 27.1) and that will get me 85.094 but thats how far it will get if it rotates 1 times so we must multiply it by 100 and move the decimal point 2 digits to the right and the final answer is 8509.4. 8509.4 (no mathematical unit) is how far the car can go when the wheels have a diameter of 27.1 and rotates 100 times.Find the circumference and area of the circle. Use 3.14 for π. Round to the nearest hundredth if necessary.
13m.
Answer:
81.64
Step-by-step explanation:
Answer:
Step-by-step explanation:
Please be explicit in labeling the radius. I will assume y ou meant r = 13 m.
Circumference formula: C = 2πr; area formula: A = πr²
Here, with r = 13 m, C = 2π(13 m) = 26π m = C = 81.68 m
and
with r = 13 m, A = π(13 m)^2 = 169π = A = 530.93 m^2
pls help i need to know what x/-4 + 6 < 11 is?!?!!?!?!
Answer:
x ∈ ( - ∞ , 20 )
Step-by-step explanation:
Given :
x / 4 + 6 < 11
Adding - 11 both we get:
= > x / 4 + 6 - 11 < 11 - 11
= > x / 4 - 5 < 0
Multiply by 4 both we get:
= > x - 20 < 0
Adding 20 both side we get:
= > x - 20 + 20 < 20
= > x < 20
Solution set x ∈ ( - ∞ , 20 )
Hence we get required answer!
9514 1404 393
Answer:
x > -20
Step-by-step explanation:
This is a "2-step" inequality with a negative coefficient.
x/-4 +6 < 11 . . . . . given
x/-4 < 5 . . . . . . . . subtract 6 from both sides
x > -20 . . . . . . . . .multiply both sides by -4
Because the multiplier is negative, the sense of the comparison must be reversed.
_____
Check
x = -24 should not be in the solution set: -24/-4 +6 < 11 ⇒ 12 < 11 . . . False
x = -16 should be in the solution set: -16/-4 +6 < 11 ⇒ 10 < 11 . . . True

The amusement park is open for 11 hours if approximately 200 people can ride the swing in one hour what is the maximum amount of people that can ride the swing in one day
Answer:
2,200
Step-by-step explanation:
Number of hours amusement park opens = 11 hours
Number of people who ride the swing in one hour = approximately 200
what is the maximum amount of people that can ride the swing in one day?
Number of people that can ride the swing in one day = Number of hours amusement park opens × Number of people who ride the swing in one hour
= 11 × 200
= 2,200 approximately
Number of people that can ride the swing in one day = 2,200

Please help in maths
Step-by-step explanation:
subtract the areas of a circle from the area of a square and divide by 4
A_square = L x W
A_circle = pi x r^2
L, W= 12cm
r= 12/2cm
(A_square - A_circle) / 4
divide by 4 since the remaining portions are symmetrical

Pryia and 3 friends go out to dinner and split the cost equally. The meal costs $98, tax is 9% and they leave a 20% tip based the cost of the meal. How much money does Pryia need?
Answer:
$42.14
Step-by-step explanation:
Given data
Cost of meal= $98
tax= 9%
Tip= 20%
Let us find the amount of the tax and the tip
Tax
=9/100*98
=0.09*98
=$8.82
Tip
=20/100*98
=0.2*98
=$19.6
Hence the total amount paid is
=98+8.82+19.6
=126.42
The amount paid by Pryia
=126.42/3
=$42.14

Answer: A. alternate interior angles
Step-by-step explanation:
Line 2 (l₂) and Line 3 (l₃) will be the focus of this question. Since both angle 3 and angle 5 are inside of the lines, they are interior angles. Since they are on alternate sides of the central line (t₁), they are alternate angles. Since they are both alternate and interior angles, they are alternate interior angles.

Answer:
[tex]x^{2} - 25[/tex]
Step-by-step explanation:
Area is side x side, so naturally it would be: (x+5)(x - 5)... Though to simplify, those parenthesis can be FOILed. (Reminder: "FOIL" means First - Outer - Inner - Last)
[tex]x^{2} - 5x + 5 x - 25[/tex]
The 5x cancels out because 5x - 5x = 0
So that leaves us with:
[tex]x^{2} - 25[/tex]
=========================================================
Explanation:
Let's say we replace the "x+5" with some other letter. Let's use L for length.
We'll keep the width x-5 the same.
area = length*width
area = L*(x-5)
area = L*x + L*(-5)
area = xL - 5L
At this point, we would then plug in L = x+5 and distribute like so:
area = x( L ) - 5( L )
area = x( x+5 ) - 5( x+5 )
area = x^2 + 5x - 5x - 25
area = x^2 - 25
Side note: (x+5)(x-5) = x^2 - 25 is an application of the difference of squares rule.
The safety rules for a playground state that the height of the slide and the distance from the base of the ladder to the front of the slide must be in a ratio of 3 : 5. What would be the length of this slide? Round your answer to the nearest whole number. ____feet
Answer: 12
Step-by-step explanation: c = √a2 + b2
= √(6)2 + (10)2
= √36 + 100
= √136
= 2√34
= 11.661903789691
Round up
12
The length of the slide has a height of 6 feet and the base of 10 feet would be equal to the nearest whole number 12 feet.
The ratio of the height of the slide and the distance from the base of the ladder to the front of the slide is 3 : 5.
The height of the slide is 6 feet.
The base of the ladder is 10 feet.
