Answer:
40
Step-by-step explanation:
210-x=50×2
or, 210-x=100
or, x=210-100
or, x=110
so,
z = 360-210-110
or, z = 40
Answer:
sin-32/40
cos-24/40
tan-32/24
Step-by-step explanation:
SOHCAHTOA
sin is opposite over the hypotenuse
cosine is adjacent over hypotenuse
tan is opposite over adjacent
plug in the numbers corresponding with angle B and you get your formulas
so sorry if my explanation was bad
Answer:
48°
Step-by-step explanation:
Not sure if you've learner this yet, but the two angles shown are called alternate exterior angles. To make it a little bit easier, 48° has to be the answer since it's the only other angle shown. But to explain it more..
There's corresponding and vertical angles which can be used to solve this equation. There are four spots that would equal 48°, including "b". Corresponding angles are in the same spot, but different sections. There's also vertical angles, which are right across from each other. If you apply vertical and corresponding angles b will be 48°.
Please let me know if you don't really understand what I attempted to explain. If you haven't gone into depths about what I talked about, just think about the first paragraph/section.
This whole problem rests on one thing:
Do you know the formula for the volume of this kind of shape ?
If you do, then the problem is easy. If you don't, then it's impossible.
This is the shape of a book, an ice cube, a brick, or a slab.
The volume is always
(length) x (width) x (height) (in any order) .
They all have to be in the same unit, and then the volume
is in the cubic-(...) of that unit.
In this picture, there's a tiny hiccup with the units ... the length and
the width are in meters, but the height is in centimeters, so you need
to change that one to meters before you can multiply them.
Notice right above the picture, it reminds you that
(1 meter = 100 centimeters) .
So the height of the slab (10 cm) is the same as 0.1 meter.
Now you have all 3 of the dimensions in meters, so you're
ready to multiply them and get the volume.
Volume = (length) x (width) x (height)
= ( 8 m ) x ( 6 m ) x ( 0.1 m )
= 4.8 cubic meters .
Question:
Does Meg have enough concrete to make the slab
with the dimensions shown ?
Answer: Yes .
Explanation:
Meg mixed 5 cubic meters of concrete.
She needs 4.8 cubic meters to pour the floor with those dimensions.
She has enough concrete to do the job.
All she needs is the whole football team to come over and help her
pour, smooth, and finish it. Concrete is hard hard work !
Answer:
200
Step-by-step explanation:
The reason why this answer is 200 is because it gave us a clue that 30 students said that pie was their favorite desert, what is half of 30? 15 so therefore, the pattern is half of each.
Ice cream: 35x2=70
Cake: 27x2=54
Candy: 23x2=46
Pie: 15x2=30
So, 70+54+46+30=200
