The amount of money would Nora have more in her account than Ella after 11 years is $714 to the nearest dollar.

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.

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.

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.

Answer:

Step-by-step explanation:

the answer is x<0

because

x-4+4<-4+4

Answer:

The ones digit or the First 7 to the left

Step-by-step explanation:

Since 10 times more

so ones place is 7

Tens place is 70

hunreds place is 600

thousands is 4000

ten thousands is 30,000

hundred thousands is 600,000

Million’s digit is 1,000,000

So since the only one with a 10 times difference is 7

So 7

The unit rate would be how many eggs one chicken lays

To do this, you would create a ratio

30:12 = x:1

30 = 12x         cross multiply

30/12 = 12x/12   isolate the variable

2.5 = x

The unit rate is 2.5:1 or [tex]\frac{5}{2}[/tex] :1

Step-by-step explanation:

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°

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]
