Stacy and Neil painted 280 ft2 of there living room wall with 4/5 gallon of paint. How many square feet can they paint with 3 gallons of paint?
Answer:
They can paint 1050 sq.feet with 3 gallons of paint
Step-by-step explanation:
Given :Stacy and Neil painted 280 ft2 of there living room wall with 4/5 gallon of paint.
To Find : How many square feet can they paint with 3 gallons of paint?
Solution :
Area painted with [tex]\frac{4}{5}[/tex] gallons of paint = 280
Area painted with 1 gallon of paint =[tex]\frac{280}{\frac{4}{5}} = 350 ft^2[/tex]
Area painted with 3 gallons of paint =[tex]350 \times 3 = 1050 ft^2[/tex]
Hence they can paint 1050 sq.feet with 3 gallons of paint

What is the solution to the inequality x2 >49 (x squared is greater than or equal to 49) plz help
To solve the inequality x² ≥ 49, take the square root of both sides and consider both positive and negative roots. The solutions are x ≤ -7 or x ≥ 7.
To solve the inequality x² ≥ 49, we need to consider the values of x that satisfy this condition. Let's break it down step-by-step:
Step-by-Step Explanation
x² ≥ 49. To solve this, we can take the square root of both sides of the inequality. Remember, when taking the square root of both sides, we must consider both the positive and negative roots.
Solve for x: |x| ≥ √49.
Since √49 = 7, the inequality becomes: |x| ≥ 7.
This implies x can be greater than or equal to 7 or less than or equal to -7.
Therefore, the solution is: x ≤ -7 or x ≥ 7.
In interval notation, this solution is written as: x ∈ (-∞, -7] ∪ [7, ∞).

A cake has a mass of 2.5kg. It contains 275g of fruit. What percentage of fruit is there in the cake
The percentage of fruit is there in the cake will be 11%.
What is mean by Percentage?
A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Given that;
Mass of cake = 2.5 kg
And, The amount of fruit = 275 g
Now,
Find the percentage of fruit is there in the cake as;
Since, Mass of cake = 2.5 kg
= 2,500 g
And, The amount of fruit = 275 g
So, The percentage of fruit = 275 / 2,500 x 100
= 0.11 x 100
= 11%
Thus, The percentage of fruit is there in the cake will be 11%.

Use the distributive property of multiplication to find 7 x 22
Hint: 22 = 20 +2
Please show all work, Thank you:)
The distributive property of multiplication is used to simplify 7 x 22. By substituting 22 with 20 + 2 and distributing the multiplication, it becomes 7 x 20 plus 7 x 2, which equals 154.
Explanation:The question is asking us to use the distributive property of multiplication to calculate 7 x 22. The distributive property allows us to multiply a single term and two or more terms inside a set of parenthesis. Here we are given the hint that 22 = 20 + 2.
Following the hint, we substitute 22 with (20 + 2) in the multiplication expression. So, 7 x 22 becomes 7 x (20 + 2). Now, by distributive property, we can take the multiplication inside the parenthesis.
7 x 20 = 140 7 x 2 = 14
By adding both these results, 140 + 14, we get the final answer 154.
