Please help really fast :)​
olasank [31]

Answer:

Step-by-step explanation:

The two smaller angles add up to the measure of the total angle, so

(like a lot of geometry) it is really just an Algebra 1 problem with a nice picture to go with it --->  (5x + 13°) + (3x + 33°) = 70°

8x + 46° = 70°

8x = 24°

x = 3°

There is no actual question shown, but I imagine you want one or more of the following:

x = 3°

∠ABC = 3(3°) + 33° = 9°+ 33° = 42°

∠CBD = 5(3°) + 13° = 15° + 13° = 28°

Hope this helps.

The table shows the relationship between the number of Calories Lucie burns while jumping rope and the number of minutes she jum
iragen [17]

Answer:

The amount of calories Lucie will burn by jumping for 1 minute is 8 calories

Step-by-step explanation:

The given data values are;

Minutes {}                  Calories Burned

40                {}            320

80        {}                    640

120 {}                          960

160 {}                          1280

The value of calories burnt and the number of minutes of jump robe are seen to be directly proportional, such that we have;

40 minutes of jump rope will yield 320 calories burnt

Therefore we have;

1 minute of jump rope will yield 320/40 = 8 calories burnt

The amount of calories Lucie will burn by jumping for 1 minute = 8 calories.

What is a number between 364 and 384 that is a multiple of both 3 and 7
masya89 [10]

Answer:

378

Step-by-step explanation:

It will also be a multiple of 21 .

As it is divisible by 3  the first possibility is 366 so:-

364 + n = 21m

where n = 2,5,8,11,14...

Trying each number in turn we get:-

364 + 14 = 21m

21m = 378

m =  18

so the answer is 378

Can I get help on this bc if I don’t do it now my math teacher will call my parents
kherson [118]

Answer:

<u>39.28cm^2 </u>

Step-by-step explanation:

Simple work out the area of a circle and halve it.

3.142xr^2

3.142x5^2 = 78.55 cm^2 (Full circle area)

Now we must halve that answer to get the semicircle.

78.55/2 = 39.275 cm^2

However, we need it to 2dp. Therefore the answer is 39.28cm^2
