Answer:
y=4
Step-by-step explanation:
4y+3=19
=4y=19-3
=y=16/4=4
Answer:
a) y = 4
b) n = 4
Step-by-step explanation:
a) 4y + 3 = 19
Subtract 3 from both sides.
4y = 16
Divide both sides by 4.
y = 4
b) Is the 1 apart of the equation? If not, these are the steps to find n.
2n - 3 = 5
Add 3 to both sides.
2n = 8
Divide both sides by 2.
n = 4
The diagram shows a square with perimeter 20 cm work out the length of the area inside the square that is shaded
Answer:
we have to find perimeter ? if yes then there are 4 sides we have to subtract 3.5cm with 3 then the answer will be added to 4

Answers:
a) 15.6b) 12c) 36d) 51.6============================================
Explanations:
Part (a)
The area of a triangle formula is A = 0.5*b*h where b and h are the base and height. You could use 1/2 in place of the 0.5
We're focused on the blue shaded triangle, which is the "floor" so to speak of this pyramid. To find the floor area, we will use b = 6 and h = 5.2 and we get
A = 0.5*b*h = 0.5*6*5.2 = 15.6
For this problem, all areas are in square inches as denoted by the [tex]\text{in}^2[/tex]
If you're curious where the b = 6 came from, it's because all sides of the equilateral triangle are the same length.
Note: The base and height of a triangle are always perpendicular.
----------------------
Part (b)
Focus on any single non-shaded triangle. Let's say we focus on the upper triangle. We have b = 6 and h = 4. It then leads to the area A = 12 sq in. This is the area of one lateral face.
------------------------
Part (c)
The instructions state that the lateral faces are congruent triangles, aka they are identical triangles. So that means we have three copies of the same area we found back in part (b), which was 12. Therefore, the lateral surface area is 3*12 = 36 square inches. As your teacher mentions, we do not include the shaded triangle as part of this result (that will happen in part d below).
------------------------
Part (d)
We add the results of parts (a) and (c) together to get the full surface area. This is the total area of the flat net, and it corresponds directly to the full surface area because we fold up the 2D figure to get the 3D one.
The total surface area is 15.6+36 = 51.6 in^2

29. Find the value of t if
t:7=1:2
Answer:
t = 7/2
Step-by-step explanation:
t:7 = 1:2
t/7 = 1/2
Cross Multiply both sides
2t = 7*1
t = 7/2
When Sally went bowling, her average scores were 108, 72, and 95 If she bowls a 4th game, what will her score need to be to give her and average of 91?
Pls hurry! I need a full explanation!!
An average is the sum of the scores divided by the number of games played.
For her average to be 91 after 4 games the total of the scores needs to be 91 x 4 = 364
To find what her 4th score needs to be subtract her first 3 scores from 364
364 - 108 - 72 - 95 = 89
Her 4th game needs to be 89

a florist orders sunflowers every 6 days, starting from the sixth day of the year, and daisies every 4 days starting from the fourth day of the year. when is the first THREE TIMES she will order the flowers on the same day?
Answer: 12th day
Step-by-step explanation:
Given , A florist orders sunflowers every 6 days and daisies every 4 days.
When it started from same day, then the next day she orders both kinds of flowers on the same day will be LCM (6,4), where LCM = Least Common Multiple.
Prime factorization:
6 = 2 x 3
4 = 2 x 2
LCM(6,4) = 2 x 2 x 3 = 12
Hence, she will order both kinds of flowers every 12 days.
