1. What is the smallest decimal in hundredths rounded to 0.5?
Answer: 0.45!
Step-by-step explanation:
The smallest decimal in hundredths rounded to 0.5 is 0.45 and this can be determined by using the rules of rounding off to the nearest hundredths.
Given :
Number - 0.5
Rules for rounding off to the nearest hundredths are:
Rule 1 - When a number is rounded off to the nearest hundred remember that the digit at tens place is in between 0 to 4 then replace that digit by 0.
Rule 2 - When a number is rounded off to the nearest hundred remember that the digit at units place is greater than or equal to 5 then replaced tens place digit by 0 and hundreds place digit is increased by 1.
So, according to the rules, the smallest decimal in hundredths rounded to 0.5 is 0.45.

Nora invested $6,300 in an account paying an interest rate of 7\tfrac{3}{4}7 4 3 % compounded continuously. Ella invested $6,300 in an account paying an interest rate of 7\tfrac{1}{4}7 4 1 % compounded monthly. After 11 years, how much more money would Nora have in her account than Ella, to the nearest dollar?
Answer:
824
Step-by-step explanation:
DELTAMATH
The amount of money would Nora have more in her account than Ella after 11 years is $714 to the nearest dollar.
What is compound interest?Compound interest is the amount charged on the principal amount and the accumulated interest with a fixed rate of interest for a time period.
The formula for the final amount with the compound interest formula can be given as,
[tex]A=P\times\left(1+\dfrac{r}{100}\right)^{t}\\[/tex]
Here, A is the final amount (principal plus interest amount) on the principal amount P of with the rate r of in the time period of t.
Nora invested $6,300 in an account paying an interest rate of 7(3/4)% compounded continuously. Convert this rate of interst in fractional form as,
[tex]r=7\dfrac{3}{4}\\r=\dfrac{31}{4}[/tex]
The principal amount of Nora is $6300 and time period is 11 years. Thus the amount in her account after 11 years will be,
[tex]A=6300\times\left(1+\dfrac{31}{4\times100}\right)^{11}\\A=14319.59[/tex]
Ella invested $6,300 in an account paying an interest rate of 7\tfrac{1}{4}7 4 1 % compounded monthly. Convert this rate of interst in fractional form as,
[tex]r=7\dfrac{1}{4}\\r=\dfrac{29}{4}[/tex]
The principal amount of Elia is $6300 and time period is 11 years. Thus the amount in her account after 11 years will be,
[tex]A=6300\times\left(1+\dfrac{29}{4\times100}\right)^{11}\\A=13605.39[/tex]
The differnce is,
[tex]d=14319.59-13605.39\\d=714.20\\d\approx714[/tex]
Thus the amount of money would Nora have more in her account than Ella after 11 years is $714 to the nearest dollar.

What is the product (4x)(-3x^6)(-7x^3
Answer:
the product of [tex](4x)(-3x^6)(-7x^3)[/tex] is [tex]\mathbf{84x^{10}}[/tex]
Step-by-step explanation:
We need to find the product of [tex](4x)(-3x^6)(-7x^3)[/tex]
For finding the product we will multiply coefficients separately and bases and their powers are multiplied separately.
[tex](4x)(-3x^6)(-7x^3)\\=4(-3)(-7)(x)(x^6)(x^3)\\[/tex]
Using the exponent law: [tex]a^m.a^n=a^{m+n}[/tex] ( When the bases are multiplied, their exponents are added)
[tex]=84x^{1+6+3}\\=84x^{10}[/tex]
So, the product of [tex](4x)(-3x^6)(-7x^3)[/tex] is [tex]\mathbf{84x^{10}}[/tex]

A drone has an effective range represented by a circle on a coordinate plane. The points (–12, 3) and (–6, –5) are endpoints of a diameter of this boundary. Which equation represents the effective range boundary for the drone?
(x + 96)^2 + (y + 1)^2 = 25
(x – 9)^2 + (y – 1)^2 = 25
(x + 9)^2 + (y + 1)^2 = 100
(x – 9)^2 + (y – 1)^2 = 100
Answer:
(x+9)^2 + (y+1)^2 = 100
Step-by-step explanation:
Since the question says diameter, we know the boundary in a circle. Therefore, we just need to find the center and radius.
The center is the midpoint of the two endpoints on a diameter.
Here, it is (-9, -1).
Therefore, the left part of the equation is (x- -9)^2 + (y - -1)^2 = (x+9)^2 + (y+1)^2.
The radius: sqrt(8^2 + 6^2) = 10
So the equation is (x+9)^2 + (y+1)^2 = 100
Answer:
A) (x + 9)^2 + (y + 1)^2 = 25

Can somebody help me!!
Answer/Step-by-step explanation:
✅m<1 = 180 - 52° = 128° (consecutive interior angles)
✅m<2 and 52° are alternate interior angles. Alternate interior angles are congruent.
Therefore:
m<2 = 52°
✅m<3 and 47° are alternate interior angles. Alternate interior angles are congruent.
Therefore:
m<3 = 47°
✅m<4 = 180 - m<3 (linear pair)
m<4 = 180 - 47 (substitution)
m<4 = 133°
✅m<5 = 180 - (52 + 47) (angles on a straight line)
m<5 = 81°

A conditional statement is shown.
"If two angles of a triangle are congruent, then it is an isosceles triangle."
Which figure represents a counterexample to this conditional statement?
A. Acute Triangle
B. Obtuse Triangle
C. Equilateral Triangle
D. Scalene Triangle
Answer:
Step-by-step explanation:
B.
The figure that represents a counterexample to the given conditional statement is option D, a Scalene Triangle.
Given that a conditional statement,
"If two angles of a triangle are congruent, then it is an isosceles triangle."
We need to determine the counterexample to this conditional statement,
A counterexample is an example that disproves a statement. In this case, if we can find a triangle where two angles are congruent but the triangle is not isosceles, it would serve as a counterexample to the given conditional statement.
A scalene triangle is a triangle where all three sides and angles are different.
If we consider a scalene triangle where two angles are congruent, it will violate the given conditional statement because it is not an isosceles triangle.
Therefore, a scalene triangle is the correct choice for a counterexample.
