a pineapple is 7 times as heavy as an orange. the pineapple also weight 870 grams more than orange what is the total weight in g

Alex Ar [27]

An orange ... o grams = ?
a pineapple ... p = 7 * o
p = 870 grams + o

If you would like to know what is the total weight in grams for the pineapple and orange, you can calculate this using the following steps:

7 * o = 870 + o
7 * o - o = 870
6 * o = 870 /6
o = 870 / 6
o = 145 grams

p = 7 * o = 7 * 145 grams = 1015 grams

Result: A pineapple weights 1015 grams and an orange 145 grams.

» Which pair of numbers has an LCM of 60?<br> 2 and 12<br> 5 and 12<br> 6 and 12<br> 3 and 12

Mariana [72]

Answer: 5 and 12

Step-by-step explanation:

2 and 12 is not it because 12 can be divided by 2 meaning that the LCM of those two numbers will be 12.

6 and 12 is not it because 12 can also be divided by 6 meaning that the LCM of 6 and 12 is also 12.

3 and 12 is also the same, 12 can be divided by 3 so their LCM will be 12.

With 5 and 12, 12 is not divisible by 5 so you will have to find the multiples of 5 and 12 and it will eventually be 60.

Multiples of 5: 5, 10,15,20,25,30,35,40,45,50,55,60,65

Multiples of 12: 12, 24, 36, 48, 60, 72

As it appears in both multiples, 60 is the least number that appears in both multiples so the LCM of 5 and 12 is 60.

If a and b are two angles in standard position in Quadrant I, find cos(a+b) for the given function values. sin a=4/5 and cos b=5

vladimir1956 [14]

First let's find the angles a and b.

We have then:
sin a = 4/5
a = Asin (4/5)
a = 53.13 degrees.

cos b = 5/13
b = Acos5 / 13
b = 67.38 degrees.

We now calculate cos (a + b). To do this, we replace the previously found values:
cos ((53.13) + (67.38)) = - 0.507688738
Answer:
-0.507688738
Note: there is another way to solve the problem using trigonometric identities.

PLEASE HELP WILL MARK AS BRAINLIEST

Answer:

$\boxed{\bold{\huge{\boxed{Area\ of\ Trapezium = 150\ cm\²}}}}$

Step-by-step explanation:

<u>Using Pythagorean Theorem first to find EC</u>

$\sf CB^2 = EB^2+EC^2\\Where \ CB = 13 \ and \ EB = 5 \\13^2 = 5^2 + EC^2 \\169 - 25 = EC^2 \\EC^2 = 144\\Taking \ sqrt \ on \ both \ sides\\EC = 12 \ cm$

<u>Given that:</u>

AE = EC

AE = 12 cm

Now,

AB = AE + EB

AB = 12 + 5

AB = 17 cm

<u>ABCD is a trapezoid / trapezium</u>

So,

Area of Trapezium = $\sf \frac{AB+DC}{2} (EC)$

Where AB = 17 , DC = 8 and EC = 12

Area of Trapezium = $\sf \frac{17+8}{2} ( 12)$

Area of Trapezium = (25)(6)

Area of Trapezium = 150 cm²
