Answer: $7,500

Step-by-step explanation:

Use the formula: SI = P(1 + rt)

SI = 5000(1 + 0.05[10])

SI = 5000 + 2500

SI = $7,500

After 10 years, your balance should be $7,500

P=80º

Start by doing 180-20 since N=20

M and P are congruent, so P = 160/2

P=80

The side of a larger cube is equal to 12 ft meanwhile the side of a small cube is equal to 4 ft.

A cube is a 3D- form of a square and its volume is found in the formula:

V=s³, where: s is the length of each side of a cube.

If the small cube has a volume ([tex]V_s[/tex]) of 64 ft³, you can apply the formula V=s³ for finding its the length of its sides. Thus

[tex]V_s[/tex]=64 ft³

[tex]s_v^3[/tex]=64

[tex]s_v=\sqrt[3]{64}\\ \\ s_v=4 ft[/tex]

A larger cube has sides ([tex]s_l[/tex]) that are three times as long as the small cube. Therefore, [tex]s_l=3s_v[/tex]. If [tex]s_v[/tex]=4 ft, the [tex]s_l[/tex] will be:

[tex]s_l=3s_v\\ \\ s_l=3*4\\ \\ s_l=12 ft[/tex]

Answer:

8m

Step-by-step explanation:

an = 2 an-1 means that each term in the sequence( except the first) is obtained by multiplying the last term by 2, so the first 4 terms are m, 2m, 4m, 8m.

Answer:

∠1 = 130°

∠2 = 50°

∠3 = 130°

Step-by-step explanation:

As we can see Angles 1 and 50° are on a straight line. As :

Angles on a straight line add up to 180. So :

50 + ∠1 = 180

∠1 = 180-50

∠1 = 130

As we can angles 1 and 2 are on a straight line. As :

Angles on a straight line add up to 180. So :

∠1 + ∠2 = 180

As we worked out ∠1 we can substitute that in to work out ∠2 :

130 + ∠2 = 180

∠2 = 180-130

∠2 = 50

As we can angles 2 and 3 are on a straight line. As :

Angles on a straight line add up to 180. So :

∠2 + ∠3 = 180

As we worked out ∠2 we can substitute that in to work out ∠3 :

50 + ∠3 = 180

∠3 = 180-50

∠3 = 130

Answer:

The area of T is equal to sum of area of R and Triangle

Step-by-step explanation:

[tex]area = 12 \times 2[/tex]

Area)= 24

[tex]area = \frac{1}{2} \times 12 \times 15[/tex]

Area= 90

Area of T = 90 PLUS 24

AREA == 114

yes and you also have $1.06 as a remainder.

Answer:

m = 30w

Step-by-step explanation:

Answer:

The answer that looks the best is m=30w

Step-by-step explanation:

I asked my teacher and he said it was right

Answer:

[tex]\sf Area\:of\:a\:triangle=\dfrac12 \times base \times height[/tex]

Given:

Substitute the given values into the equation and solve for h:

[tex]\sf \implies 18 = \sf \dfrac12 \times 6 \times (h+1)[/tex]

[tex]\sf \implies 18 = \sf \dfrac62 (h+1)[/tex]

[tex]\sf \implies 18 =3(h+1)[/tex]

expand using distributive property of addition [tex]a(b+c)=ab+ac[/tex]:

[tex]\sf \implies 18=3h+3[/tex]

subtract 3 from both sides:

[tex]\sf \implies 3h=15[/tex]

divide both sides by 3:

[tex]\sf \implies h=5[/tex]

To verify:

Half of the base is 3 cm.

If h=5, then the height of the triangle is 6 cm.

Multiplying 3 by 6 is 18.

This matches the given area, so we can verify that h = 5.

Answer:

Below!

Given:

Formula:

[tex]\text{Area of triangle} = \dfrac{1}{2} \times \text{Base} \times \text{Height}[/tex]

Substitute the measures into the formula:

[tex]:\implies 18 \ \text{cm}^{2} = \dfrac{1}{2} \times 6 \times \text{(h} + 1\text{)}[/tex]

SImplify the R.H.S:

[tex]:\implies18 \ \text{cm}^{2} = 3 \times \text{(h} + 1\text{)}[/tex]

Divide both sides by 3:

[tex]:\implies \dfrac{18}{3} = \dfrac{3 \times \text{(h} + 1\text{)}}{3}[/tex]

Simplify both sides:

[tex]:\implies 6 = \text{(h} + 1\text{)}[/tex]

Subtract 1 both sides:

[tex]:\implies 6 - 1 = \text{h} + 1- 1[/tex]

Simplify both sides:

[tex]:\implies 5= \text{h}[/tex]

Reviewing on how to verify our answer:

We can verify our answer by substituting the value of "h" in (h + 1) to determine the height of the triangle. Then we can substitute the height and the base in the "area of triangle" formula (1/2 x Base x Height).

Verifying our answer through mental math:

Thus, the value of "h" is verified through mental math.

The solution of the logarithmic equation is given by the antilog. Then the value of x is 2 and 4.

It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.

The logarithmic equation is given below.

[tex]\log _6(x^{2} +8)= 1+ \log _6x\\\\\log _6(x^{2} +8)= \log_66+ \log _6x\\\\\log _6(x^{2} +8)= \log _66x\\[/tex]

Take antilog, then we have

[tex]\begin{aligned} x^{2} +8 &= 6x\\\\x^2 -6x + 8 &= 0\\\\x^2 -4x - 2x +8 &=0\\\\(x-4)(x-2) &= 0\\\\x&= 2, 4\end{aligned}[/tex]

Then the value of the x is 2 and 4.

Answer:

It is B.

Step-by-step explanation:

explanation is in the pic.

The perimeter of the rectangle of length (x₂ - x₁) and width (y₂ - y₁) will be 2(x₂ - x₁) + 2(y₂ - y₁). Then the correct option is A.

It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a rectangle, opposite sides are parallel and equal and each angle is 90 degrees. And its diagonals are also equal and intersect at the mid-point.

The length of the rectangle will be (x₂ - x₁) and the width of the rectangle will be (y₂ - y₁).

Then the perimeter of the rectangle will be

Perimeter = 2(x₂ - x₁) + 2(y₂ - y₁)

Cindy's new rent when she includes the renter's insurance will be C. $836.08.

As an insurance policy, renters insurance offers the policyholder insurance coverage over personal belongings, liabilities, and living expenses.

Data and Calculations

Annual insurance premium = $565.00

Monthly insurance premium = $47.08 ($565/12)

Current monthly rent = $789.00

Cindy's new rent with the renters insurance included = $836.08 ($789.00 + $47.08).

Thus, Cindy's new rent when she includes the renter's insurance will be C. $836.08.
