The ratio of the height of a wall to the length of the wall is 2:3. the area of the wall is 384 sq. ft. what are the height and length of the wall?
The dimensions of the wall are found by defining variables based on the given ratio and area, resulting in a height of 16 ft and a length of 24 ft.
The question involves finding the dimensions of a wall given the ratio of its height to length and its total area. To solve this, let's denote the height of the wall as 2x and the length of the wall as 3x, based on the ratio 2:3. The area of the wall is the product of its height and length, which means (2x) ×(3x) = 384 sq. ft.
Now, by simplifying the equation, we get [tex]6x^2[/tex] = 384. Dividing both sides by 6 gives us [tex]x^2[/tex] = 64. Taking the square root of both sides, we find x = 8. Therefore, the height of the wall is 2x = 16 ft and the length of the wall is 3x = 24 ft.
What happens to people who don’t know toothpaste from putty?
Final answer:
Toothpaste is designed specifically for oral hygiene and contains abrasives and fluoride, unlike putty. Recognizing and using toothpaste instead of incorrect substances like putty is crucial for maintaining dental health.
Explanation:
When a person does not know how to distinguish between toothpaste and putty, they may lack basic knowledge about oral hygiene and the purpose of toothpaste. Toothpaste is formulated to clean and maintain the health of teeth; it usually contains abrasives that scrub the teeth and fluoride that helps prevent cavities.
It is essential to use toothpaste rather than any other substance, such as putty, which does not provide the same benefits and can be harmful if ingested. Learning to recognize and use toothpaste correctly is part of basic health awareness and contributes to overall wellbeing.

Find the value of z /2 that corresponds to a confidence level of 89.48%.
Answer: [tex]1.6202[/tex]
Step-by-step explanation:
The given confidence level : c= 89.48%.
⇒ c= 0.8948 [ in decimal]
Then, the significance level = [tex]\alpha= 1-c[/tex]
[tex]=\alpha= 1-0.8948=0.1052[/tex]
Now, to find the value of [tex]z_{\alpha/2}[/tex] , we need to find the two -tailed z-value using z-table for [tex]\alpha=0.1052[/tex] or we can also find the one-tailed z-value for for [tex]\alpha/2=0.1052/2=0.0526[/tex]
Using z-value table , the value is [tex]1.6202[/tex]
Hence , [tex]z_{\alpha/2}=1.6202[/tex] that corresponds to a confidence level of 89.48%.
Using confidence interval concepts, it is found that the critical value is [tex]z_{\frac{\alpha}{2}} = 1.62[/tex]
For a confidence level of [tex]\alpha[/tex], the critical value of z is z with a p-value of:
[tex]\frac{1 + \alpha}{2}[/tex]
The p-value is found looking at the z-table.In this problem, confidence level of 89.48%, thus [tex]\alpha = 0.8948[/tex] the p-value of the z-score is:
[tex]\frac{1 + 0.8948}{2} = 0.9474[/tex]
Looking at the z-table, this value is [tex]z_{\frac{\alpha}{2}} = 1.62[/tex].

What is the GCF of the terms in 4a^4+6a^2?
The GCF (Greatest Common Factor) of the terms in the algebraic expression 4a^4+6a^2 is found by observing the numerical coefficients (4 and 6) and the variables (a^4 and a^2). The GCF of 4 and 6 is 2, and the GCF of a^4 and a^2 is a^2, so the GCF of the terms in the expression is 2a^2.
Explanation:The GCF (Greatest Common Factor) of two or more terms is the greatest number that divides each of the terms without any remainder. The GCF of the terms in the algebraic expression 4a^4+6a^2 can be found by observing the numerical coefficients and the variables.
1. The numerical coefficients of the terms are 4 and 6. The GCF of 4 and 6 is 2.
2. The variables in the terms are a^4 and a^2. The GCF of a^4 and a^2 is a^2, because a^2 is the factor that appears in both terms to the smallest power.
By combining the GCF of the numerical coefficients with the GCF of the variables, we find that the GCF of the terms in the algebraic expression 4a^4+6a^2 is 2a^2.

Linda has completed 24 deliveries so far this week. she needs to make 40 deliveries for the week. what percentage of her deliveries has linda completed?
Final answer:
Linda has completed 60% of her deliveries for the week.
Explanation:
Linda has completed 24 deliveries out of a total of 40 deliveries for the week. To find the percentage of deliveries Linda has completed, we can divide the number of completed deliveries by the total number of deliveries and multiply by 100.
Percent of deliveries completed = (Number of completed deliveries / Total number of deliveries) * 100
Percent of deliveries completed = (24/40) * 100 = 60%

Natasha wants to use the fermi process to estimate the number of pennies that would fill a toy chest. as part of the process, she needs to estimate the volume of the toy chest. she figures the toy chest is about 50 in. long, 20 in. wide, and 20 in. tall. which estimate best approximates the volume of the toy chest? 2×103 in³ 2×104 in³ 2×105 in³ 2×106 in³
Answer:
Dimension of toy chest
Length =50 inches
Width = 20 inches
Height = 20 inches
Volume of toy chest = Length × Breadth ×Height
= 50 ×20 × 20
= 1000 × 20
= 20,000 inches cube.
[tex]=2\times 10^4 inches ^3[/tex] appears best approximation.

Angles 4 and 5 form what type of angles?
Angles 4 and 5 form a pair of vertical angles. Vertical angles are two angles that are opposite each other when two lines intersect. They have the same measure and are congruent.
Vertical angles are a pair of angles formed when two lines intersect. In this case, angles 4 and 5 are considered vertical angles because they are opposite each other at the point where the lines intersect. These angles have a special property: they are congruent, which means they have the same measure. This is a fundamental principle in geometry.
Imagine drawing two straight lines that intersect, creating four angles. Angles 4 and 5 are positioned opposite each other, and they share the same measurement. This relationship is true regardless of the lengths of the lines or the specific angles involved. It's a geometric rule that holds true in all cases where vertical angles are formed.
Understanding vertical angles is important in various mathematical and geometric applications, as it allows us to make deductions about the relationships between angles and lines in different configurations.
