Original shirt cost: $55. Current shirt cost $40 find the percent decrease round to the nearest whole percent

ioda

Answer:

Step-by-step explanation:

Original cost = $55

Current price = $40

Decrease in price = 40-55 = -$15

Percentage decrease = [(New price - old price)/ old price] *100

Percentage decrease = (40-55)/55] *100

= -0.272727 *100

= -27.27%

To a whole percentage = 27%

Therefore, the cost of the t-shirt decreased by 27%

✓-90= Ai√B<br> What is the value of A?<br> What is the value of B?

olga2289 [7]

Answer:

A = 3, B = 10

Step-by-step explanation:

$\sqrt{-90}$

= $\sqrt{9(-1)(10)}$

= $\sqrt{9}$ × $\sqrt{-1}$ × $\sqrt{10}$

= 3i $\sqrt{10}$

Draw a rectangular fraction model to explain your thinking. Then, write a multiplication sentence. A. 2 3 of = 3 5

myrzilka [38]

Answer:

$\frac{2}{3}\ of\ \frac{3}{5} = \frac{2}{5}$

Step-by-step explanation:

Given

$\frac{2}{3}\ of\ \frac{3}{5}$

Solving (a): Multiplication sentence

$\frac{2}{3}\ of\ \frac{3}{5}$

Rewrite of as *

$\frac{2}{3}\ of\ \frac{3}{5} = \frac{2}{3}\ *\ \frac{3}{5}$

Solve

$\frac{2}{3}\ of\ \frac{3}{5} = \frac{2}{5}$

Hence, the multiplication sentence is:

$\frac{2}{3}\ of\ \frac{3}{5} = \frac{2}{5}$

Solving (b): Rectangular fraction model

In (a) above, the result is 2/5

The fraction model will be represented as thus:

Draw a rectangle
Partition in to 5 equal parts (5 represents the denominator)
Shade 2 of the 5 partitions (2 represents the numerator)

Hey guys help my please !!Q 4,6,7

padilas [110]

Q4, 4y²=60
y=√15 ( i am not sure)
q6, (5+y) ²=81
5+y=9
y=4
q7 (x+4) (x) =77
x²+4x-77=0
(x+11) (x-7) =0
x=-11(rej) or x=7
therefore ,length= 7+4=11cm
breadth=7cm
