We can use the compound interest formula

F=P(1+i)^n

where

F=Future value of investment to be found

P=present value of investment ($1000)

i=interest per period (1/4 year)=0.04/4=0.01

n=number of periods (3 years * 4 quarters = 12)

Substitute or "Plug in" values, so to speak,

F=1000*(1+0.01)^12

use a calculator to do the sum

=1126.83 (to the nearest cent, and use the proper rounding rules)

A kids skipping rope is 7ft long. How many ropes could I cut from a 10 yard long piece of rope?

Hatshy [7]

3 feet are in one yard
so 3 ×10 =30
so 30 ÷ 7 = 4.2
Answer is 4
even is there if there is a decimal only 4 can be made

Given the information w = 4 inches and h = 7 inches, find two ways to evaluate 2w+2h. What is the geometric significance of this

joja [24]

I believe the 2 ways would be
$2w + 2h$
and
$2(w + h)$

and this equation is significant because it is the perimeter formula

Triangle tic is an isosceles triangle with vertex angle i if the measure of < i=70 then find the measure of < t a- 70 b-11

Andreas93 [3]

Answer:

The answer is the option C

$55\°$

Step-by-step explanation:

we know that

An isosceles triangle has two equal sides and two equal angles

The two equal angles are called the base angles, and the third angle is called the vertex angle

In this problem we have the isosceles triangle TIC

∠I= $70\°$ -----> vertex angle

∠T=∠C -----> base angles

Remember that the sum of the internal angles of a triangle is equal to $180\°$

∠I+∠T+∠C= $180\°$

∠I+2∠T= $180\°$

Substitute

$70\°$ +2∠T= $180\°$

Solve for angle T

2∠T= $180\°-70\°$

∠T= $110\°/2$

∠T= $55\°$

7. A clothing salesman wants to earn $6,000 in May. He receives a base salary of $4,000 per month as well as 10%

olya-2409 [2.1K]

Answer:

No of clothes to be sold to gain $6000=20,000

Given:

Base salary = $4000

Rate of Commission = 10%

Amount salesman wants to earn in May = $6000

To find:

How much clothing units needed to be sold in order gain $6000 in may

<u>Step by Step Explanation: </u>

Solution;

According to the formula;

$\text { Amount earned through commission }=\text { Total amount earned - Base salary }$

=6000 - 4000 = 2000

Also we know,

$\text { Amount earned through commission }=\text { Rate of Commission } \times \text { clothing to be sold }$

Let the commission amount be x

$10 \% \times x=2000$

$10 / 100 \times x=2000$

$0.1 \times x=2000$

$x=20,000 \div 0.1$

x=20,000

Result:

Hence, the clothing to be sold in order to earn $6000 is 20,000 units.

The function f(t) = t2 + 6t − 20 represents a parabola.

Charra [1.4K]

For t²+6t-20=0 (to find the vertex, or rather the x intercepts), we can add 20 to both sides to get t²+6t=20. Since 6/2=3, we can square 3 to get 9. Adding 9 to both sides, we get t²+6t+9=20+9=29=(t+3)². Finding the square root of both sides, we get t+3=+-√(29). Subtracting 3 from both sides, we get t=+-√(29)-3=either √(29)-3 or -√(29)-3. We have -√(29)-3 due to that t can either be negative or positive. Finding the average of the two numbers, we have
(√(29)-3)+(-√(29)-3./2=-6/2=-3, which is our t value of our vertex and since it's t² and based around t, that is our axis of symmetry. To find the y value of the vertex, we simply plug -3 in for t to get 9+(6*-3)-20=9-18-20=-29, making our vertex (-3, -29)
