1.2, 0, -0.4, -2.6, 0.8
HELP PLS!
Answer: -2.6 , - 0.4, 0, 0.8 , 1.2
Step-by-step explanation:
ascending is smallest to largest
From the extrem left of a.number line to the right
Answer:
-2.6, -0.4, 0, 0.8, 1.2
Step-by-step explanation:
Ascending order is simply the smallest number to the largest number. The smallest numbers in this set are the negative ones, and -2.6 is a smaller value than -0.4.
So far our set looks like the following:
-2.6, -0.4
Next is 0, since 0.8 and 1.2 both come after 0. After 0 would be 0.8, and 1.2 would be the largest number.
Here is the set of numbers in ascending order:
-2.6, -0.4, 0, 0.8, 1.2

Answer:
1st Statement: False
2nd Statement: True
3rd Statement: True
4th Statement: False
Answer:
False
True
False
True
Step-by-step explanation:
Whole numbers are 'counting numbers', they don't include decimals. (ex. 1, 2, 3) Integers are non-decimal numbers and they can be negative too. (ex. -5, 0, 4). Since whole numbers are non-decimal numbers that are greater than or equal to 1, they are all integers. So this statement is False.
Rationals numbers include all numbers that are not infinite decimals. They can be fractions as long as they are not infinite and since whole numbers cannot be fractions, this statement is True.
As with the previous statement, rational numbers can be fractions and integers cannot be fractions. So, not all rational numbers are integers so this statement is False.
Rational numbers are all numbers that are not infinite decimals, so, that includes whole numbers. This statement is also True.
A rectangular cracker has a length of 5 centimeters and an area f 20 square centimeters. Find its perimeter.
Answer:
18cm
Step-by-step explanation:
We have the length of the rectangle but we need to find the width which we'll call w. Area is a, l is length.
a = l * w
20 = 5 * w
divide both sides by 5 to cancel the multiplication by 5 on the right side
4 = w
The rectangle is going to have two sides that are the length of l, and two sides that are the the length of w. We're looking for the perimiter p.
p = 2l + 2w
p = (2 * 5) + (2 * 4)
p = 18

(Note: No Solution considered wrong)
Answer:
1) 40 m; 2) 18 cm
Step-by-step explanation:
1) Length = 10 m
Breadth = 4 m
Perimeter of a rectangle
= length (l) × breadth (b)
= 10 × 4
= 40 m
2) Side 1 = 6 cm
Side 2 = 8 cm
Side 3 = 4 cm
Perimeter of a triangle
= Side 1 + Side 2 + Side 3
= 6 + 8 + 4
= 18 cm
_______
Hope it helps ⚜
Answer:
1. 28m
2. 18 cm
Step-by-step explanation:
Perimeter of rectangle = 2× (length + breadth )
=> 2 ( 10 + 4 )
=> 2 ( 14 )
=> 28 m
Perimeter of triangle = side a + side b + side c
=> 6cm + 8cm + 4cm
=> 18 cm

The graph of the function f(x)=x^2-6x shifted 2 units to the left on the graph of g(x). Select the two functions that represent the shift of f(x) onto g(x)
Answer:
Step-by-step explanation:
g( x ) = f ( x + 2 )
g(x) = ( x + 2 )² - 6 ( x + 2 )
g(x) = x² + 4x + 4 - 6x - 12
g(x) = x² - 2x - 8
1. Select all equations that have select all graphs with the same y-intercept.
Ay = 3x - 8
B.y = 3x - 9
c. y = 3x + 8
D. y = 5x - 8
E. y = 2x - 8
F. y = 1/3x -8

Find the surface area of the prism.
m2
Answer:
324 square meters
Step-by-step explanation:
Hey there!
The surface area of a shape is the area of all the surfaces added up
The side surface area is 48 since 16 x 3 is 48. Since there are two side areas, we need to multiply 48 x 2 is 96
Now we need to do this for the other sides
the bottom and top areas are 96 square meters each so we multiply 96 by 2 which is 192
The front and back faces have an area of 18 square meters so we multiply 18 by 2 since there are two faces which are 36
Now we add all the values: 96+192+36 which is 324
So the surface area of the prism is 324 square meters

What is the area of a circle with a diameter of 4x? Please I need help rn
Answer:
12.57x² units²
Explanation:
area of circle: πr² ["r" denotes radius]
diameter: 2r
Given,
diameter: 4x
radius: 4x/2 = 2x
Area of circle:
πr²
π(2x)²
π(4x²)
4πx²
12.57x²
Answer:
4πx² square units
Step-by-step explanation:
Area of a circle
[ A = πr² ]The formula uses the radius of the circle, but we have the diameter. Remember the relation :
Diameter = 2 x Radius4x = 2 x RadiusRadius = 4x/2 = 2xNow, we can solve.
⇒ A = πr²⇒ A = π(2x)²⇒ A = 4πx² square unitsThe deck off the back of the house creates a right triangle. The side of the deck resting against the house is the hypotenuse of the triangle. You decide to put new stain on the wood. One edge of the deck measures 15 feet and the other edge of the deck measures 20 feet. Answer the follow- ing questions: 1. What is the area of the deck? 2. Each gallon of stain covers a maximum of 350 square feet. How many do you need? 3. If each gallon costs $36.98, what will the project cost you?
Approximately 2 gallons will be needed if each gallon of stain and the project will cost be $73.96 if each gallon costs $36.98
How to find the area of a triangleThe formula for calculating the area of a triangle is expressed as:
A = 0.5bh
where
base = 15feet
height = 20feet
Area of the deck = 20 * 15 * 0.5
Area of the deck is 150 square feet
Number of gallons needed = 350/150 = 2.3
Hence approximately 2 gallons will be needed if each gallon of stain covers a maximum of 350 square feet.
Cost of the two gallons = 36.98 * 2
Cost of the two gallons = $73.96
Hence the project will cost be $73.96 if each gallon costs $36.98

The measure of an angle is eighty-nine times it's supplementary angle. what is the measure of each angle.
I need two answers,
Answer:
178 and 2
Step-by-step explanation:
sum of supplementary angles are 180
so, x+ 89x = 180
=> x+89x = 180
=> 90x = 180 [the transposing method]
=> x = 180/90
=> x = 2
now we have the value of one angle
as the other angle is 89 times x,
=> 89x
=> 89*2
=> 178
now, we have the measure of both the angles which equals 180 degree
178 degree and 2 degree

Prices for bicycles are given below
The price of a red bike is the price of a blue bike is 2/3
The price of a green bike is 5/4
Since the price of a green bike is $210 more than the price of a blue bike, how much does a red bike cost?
A) $360 B) $440 C) $560 D)$720
Answer:
C) $560
Step-by-step explanation:
Suppose that: r=price of red bike , b=price of blue , g=price of green.
Given: r=(2/3)b g=(5/4)b g=210+b
Solution:
(5/4)b=210+b (g=g)
(5/4)b-b=210 (take b as common factor)
b((5/4)-1)=210
b(0.25)=210
b=210/0.25=$840 (so the price of blue bike is 840$)
Substitute b in equation of r:
r=(2/3)b=(2/3)(840)=560
so red bike costs $560.
