ABCD is a trapezium
AD=10cm
AB=9cm
DC=3cm
Angle ABC=angled BCD=90degrees
Calculate the length of AC
Give your answer correct to 3 significant figures
Answer:
12.0 cm
Step-by-step explanation:
✔️First, find the height, BC, of the trapezium using Pythagorean Theorem.
BC² = 10² - (9 -3)²
BC² = 10² - 6²
BC² = 64
BC = √64
BC = 8 cm
✔️Find AC using Pythagorean Theorem:
AC² = AB² + BC²
AC² = 9² + 8²
AC² = 145
AC = √145
AC = 12.0415946 ≈ 12.0 (3 significant figures)

Hiya! Here's my question:
A baker uses 80 grams of salt for each batch of bread. Salt comes in a 32-kilogram package or a 1,700-gram package. Which size package should the baker buy so that no salt is left after all of the batches are made? Explain.
(I really need to answer this quickly, thanks! ^^)
wait i got it!
Since 18 kilograms are 18000 grams, you have
18000/30=600
and
800/30=26.6
So, with 18 kilograms of salt the baker can make exactly 600 batches with no leftovers, while with 800 grams of salt the baker can make 26 batches, with some leftovers.
In fact, 26 batches require
26 x 30 =780
grams of salt, and the remaining
800-780=20
grams of salt are not enought to prepare the next batch

En una pension de perros hay tres perros que pesan 20kg 10kg y otro 5kg si se contempla que 70kg de alimento dura 2 meses¿que cantidad de alimento le toca a cada perro ? Problema de proporcionalidad inversa
Answer:
40kg
20kg
10kg
Step-by-step explanation:
The computation of the food each one is getting as follows
Total weights of all dogs
= 20 kg + 10 kg + 5kg
= 35 kg
And, the food is 70 kg
So, each one is getting
for 20 kg
= 70 ÷ 35 × 20
= 40 kg
For 10 kg
= 70 ÷ 35 × 10
= 20 kg
And, for 5 kg
= 70 ÷ 35 × 5
= 10 kg
Write the slope-intercept inequality for the graph below.
Answer: y <= -3x + 3
-----------------------------------------
Explanation: The slope of the boundary line is -3 because we go down 3 over 1 each time we go from point to point. We can use the slope formula to get
m = (y2-y1)/(x2-x1)
m = (-3-3)/(2-0)
m = -6/2
m = -3
The y intercept is 3 because this is the location on the y axis where the graph crosses, so b = 3
Therefore the boundary line equation is y = -3x+3. Note how it's in the form y = mx+b where m = -3 and b = 3
The boundary line is solid. The shading is below the boundary line. So we change the equal sign to a "less than or equal to" sign to get the final answer of y <= -3x+3

,LCM of 12 and 30 is 60
Answer:
List the first five multiples of 30
The first 5 multiples of 30 are: 0, 30, 60, 90, 120.
What is the lowest common multiple of 12 and 30
for LCM (12,30) we find:
Prime factorization of 12 = 2 × 2 × 3.
Prime factorization of 30 = 2 × 3 × 5.
Using all prime numbers found as often as each occurs most often we take 2 × 2 × 3 × 5 = 60.
Therefore LCM (12,30) = 60

Answer:
A. (3,2) . I recommend using desmos to find the coordinates
9514 1404 393
Answer:
A. (3, 2)
Step-by-step explanation:
The midpoints of the diagonals are the same point, so you have ...
X = (A +C)/2 = (B +D)/2
A +C = B +D . . . . . . . multiply by 2
A +C -B = D . . . . . . . subtract B
The coordinates of D are ...
D = (3, 6) +(6, 3) -(6, 7) = (3+6-6, 6+3-7)
D = (3, 2)

the product of lisa and her twin brother is 36 and their sum is 36 how old can lisa be
Answer:
6 years old
Step-by-step explanation:
Since her twin brother is the same age as her, you are looking for two equal factors whose product is 36. The square root of 36 is 6, so the answer is they are both 6 years old.
Find the measure of angle A
Answer:
30
Step-by-step explanation:
(x + 37) + (x + 67) + 90 = 180 by the Triangle Angle Sum Theorem
(x + 37) + (x + 67) = 90
2x + 104 = 90
2x = -14
x = -7
(-7 + 37) = angle A
angle A = 30
Answer:
<a = 30
Step-by-step explanation:
x + 37 + x + 67 + 90 = 180
<A + <B + <C = 180
*take each angle, add them, and equal them to 180*
x + 37 + x + 67 + 90 = 180
*solve for x*
2x + 194 = 180
-194 -194
2x = -14
x = -7
<a = x + 37
<a = (-7) + 37
<a = 30
<b = x + 67
<b = (-7) + 67
<b = 60
<c = 90
