What is the product of 0.51 × 0.24?<br><br> 0.1224<br> 1.124<br> 11.24<br> 1124

natima [27]

0.52 x 0.24 means "about a half times 0.24". Given the multiple choice answers, the correct answer is therefore 0.1224 (since this is the only one smaller than 0.24).

Proof:
0.50 × 0.24 = 0.12
0.01 × 0.24 = 0.0024
And therefore 0.51 × 0.24 = 0.12 + 0.0024 = 0.1224

can someone help me understand this? The length of the rectangle is two more then its width. the perimeter of the rectangle is 7

Tema [17]

Answer:

length = 24 meters

Step-by-step explanation:

1. l = 2w

2. P = 2l + 2w

P=72

3. 72 = 2l + 2w

4. Substitute w=l/2 to solve for l

72 = 2l + 2(l/2) ---> 72 = 3L - Divide by 3 on both sides

L= 24 meters

Given: ∆PST, PT = 8, m∠T = 90°, m∠S = 48° Find: perimeter of ∆PTS

ohaa [14]

Answer:

$P=25.98\ units$

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The perimeter of triangle PST is equal to

$P=PT+PS+TS$

step 1

Find the length PS

In the right triangle PST

$sin(48\°)=\frac{PT}{PS}$ ---> opposite side angle of 48 degrees divide by the hypotenuse

substitute the given values

$sin(48\°)=\frac{8}{PS}$

Solve for PS

$PS=\frac{8}{sin(48\°)}$

$PS=10.77\ units$

step 2

Find the length TS

In the right triangle PST

$cos(48\°)=\frac{TS}{PS}$ ---> adjacent side angle of 48 degrees divide by the hypotenuse

substitute the given values

$cos(48\°)=\frac{TS}{10.77}$

Solve for TS

$TS=cos(48\°)(10.77)$

$TS=7.21\ units$

step 3

Find the perimeter

$P=PT+PS+TS$

we have

$PT=8\ units$

$PS=10.77\ units$

$TS=7.21\ units$

substitute

$P=8+10.77+7.21=25.98\ units$
