please help, would be greatful :)
Answer:
1. a = 21°
2. b = 70°
3. c = 89°
Step-by-step explanation:
1. Determination of the value of a.
a = 21° (vertically opposite angles are equal)
2. Determination of the value of b.
From the question given above,
110 + b = 180 (sum of angles on a straight line)
Collect like terms
b = 180 – 110
b = 70°
3. Determination of the value of c.
a + b + c = 180 (sum of angles in a triangle)
a = 21°
b = 70°
c =?
21 + 70 + c = 180
91 + c = 180
Collect like terms
c = 180 – 91
c = 89°
John and 2 friends each ate 5/6 of pizza, how many pizza's did the consume all together
Answer:
2 [tex]\frac{1}{2}[/tex]pizzas
Step-by-step explanation:
The equation to this question can be written as 5/6 + 5/6 + 5/6 or 5/6 x 3.
To multiply 5/6 by 3, we can set it up as [tex]\frac{5}{6} * \frac{3}{1}[/tex]. Now to multiple, we just multiply straight across. We do 5 * 3 over 6 * 1 to get 15/6. Now, all we have to do is simplify the fraction. 6 goes into 15 two times, so we know they ate 2 pizzas. Now we are left with 3/6. 3/6 can be rewritten as [tex]\frac{1}{2}[/tex]. In total, they ate 2 [tex]\frac{1}{2}[/tex] pizzas.

2)what is the ratio of 400m to 1.5km
Answer:
4km/1.5km
Step-by-step explanation:
hope that helps :)
Ratio of 400m to 1.5km is 400/1500 or 400:1500
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Here the given quantities are 400m and 1.5km
The quantities are with different unit
We convert them into same unit
We know that one kilometre=1000 metre
One kilometre equal to thousand metres.
Let us convert 1.5 km to metre by multiplying 1.5 with 1000
1.5×1000=1500
The ratio of 400m to 1.5km is 400/1500 or 400:1500
Hence ratio of 400m to 1.5km is 400/1500 or 400:1500

Find Surface Area! WILL MARK BRANLIEST PLEASE HURRY!
Answer:
1164
Step-by-step explanation:
Surface area is the sum of the areas for all the faces. So 20×15= 300 since there is another one like that you multiply that answer by 2. Then 16×12= 192 then repeat and multiply 192 by 2. Then 12×15= 180 and since there is only one you dont multiply it by 2. Now add (192×2) + (300×2) + 192.
384 + 600 + 192 = 1164

Answer:
x = 13
Step-by-step explanation:
Right Triangles
In a right triangle, there is an internal angle of 90°. The other two must add up to 90°.
The trigonometric ratios are satisfied in a right triangle. The tangent ratio, for example, is defined as:
[tex]\displaystyle \tan 35^\circ=\frac{\text{opposite leg}}{\text{adjacent leg}}[/tex]
The angle of 35° is adjacent to the side of length 18 and is opposite to the side of length x, thus:
[tex]\displaystyle \tan 35^\circ=\frac{x}{18}[/tex]
Solving for x:
[tex]x=18\tan 35^\circ[/tex]
This is the equation to solve. Now substitute the tangent for its value to get
x = 13

Answer:
The nth term is 3n+2.
The given sequence is in A.P.
Here,
First term,a= 5
Common difference,d= 3
Therefore the nth term = a+(n-1)d =5+(n-1)3

Mia made three times as many baskets in yesterday’s basketball game as she did last Saturday. She scored a total of 24 baskets for both games. How many baskets did Mia score last Saturday?
Please show me how to do it and the answer. :)
Answer:
Mia scored 6 baskets Last Saturday.
Step-by-step explanation:
Let:
Mia made score of baskets on Last Saturday = x
Mia made score of baskets yesterday = 3x (Mia made three times as many baskets in yesterday’s basketball game as she did last Saturday. three times means multiply 3 with score of Last Saturday baskets, i.e. x)
Total score of baskets = 24
We need to find How many baskets did Mia score last Saturday?
We can write:
Total Score = Score on Last Saturday + Score yesterday
[tex]24=x+3x[/tex]
Solving this equation we can find value of x:
[tex]24=x+3x\\24=4x\\=>4x=24\\x=\frac{24}{4}\\x=6[/tex]
So, we get value of x = 6
Mia made score of baskets on Last Saturday = x = 6
Mia scored 6 baskets Last Saturday.
