Answer:
Step-by-step explanation:
Dacă adaug un sfert de la jumătate de b și o treime de c, obțin 120.
Aceasta se exprimă ca:
1 / 4a + 1/2 b + 1 / 3c = 120 ..... Ecuația 1
Știind că jumătate din b este de 24 de ori mai mare decât un sfert de a
1 / 2b = (1/4 × a) 24
b / 2 = (a / 4) 24
b / 2 = 6a
Cross Multiply
b = 6a × 2
b = 12a
a = b / 12
Jumătate din b este de 4 ori mai mare decât o treime din c
1/2 × b = 4 × (1/3 × c)
b / 2 = 4 (c / 3)
b / 2 = 4c / 3
Cross Multiply
b = 2 × 4c / 3
b = 8c / 3
8c = 3b
c = 3b/8
1 / 4a + 1/2 b + 1 / 3c = 120 ..... Ecuația 1
Înlocuim
1/4 × b / 12 + 1 / 2b + 1/3 × 3b / 8= 120
b / 48 + b / 2 + b/8 = 120
Înmulțiți cu 48
b/48 × 48 + b/2 × 48 + b/8× 48 = 120 × 48
b + 24b + 6b = 5760
31b = 5760

Separate it like this:
chop of the rectangle part and find the area of that and then add it to the trapezoid part
10*20 = 200.
Area of a trapezoid = 5+10/2 *6.
5+10 = 15. 1
5/2 = 7.5.
7.5*6 = 45.
45 + 200 = 245

a force of 10 newtons act in a direction 75 above horizontal moving an object 15 meters from (0,0) to (15,0). What is the work done by the force?
A. 2.59 joules
B. 3.88 joules
C. 38.82 joules
D. 150.00 joules
Answer:
C
Step-by-step explanation:
i think
The required work done is 38.82 joules.
Work done to be determine for force of 10 newton on angle of 75° for 15 meters.
Work done is define as the force required to move an object by some displacement.
Here, work done = force x displacement x cosФ
= 10 x 15 x cos75°
= 150 x 0.25
= 38.82 joules
Thus, the required work done is 38.82 joules.

Write each percent as a fraction in simplest form. 16%
PLEASE CAN YOU ANSWER THIS? AND IF YOU CAN PLEASEEEEEEEEEE EXPLAIN HOW YOU GOT IT, THANKS!
Answer:
[tex]\frac{4}{25}[/tex]
Step-by-step explanation:
16% is equal to [tex]\frac{16}{100}[/tex]
[tex]\frac{16}{100}[/tex] can be simplified by dividing by 2, giving you [tex]\frac{8}{50}[/tex], which can be divided by 2 again, giving you [tex]\frac{4}{25}[/tex].
[tex]\frac{4}{25}[/tex] can't be simplified again.
Answer:
16% = 4/25
Step-by-step explanation:
First, turn the percentage (16%) into a fraction with 100 in the denominator:
16% = 16/100
Now, you just need to simplify 16/100:
16/100
= 4/25
Both sides were divided by 4 to get the most simplified answer because 4 is the greatest common factor of 16 and 100.

Sandra hikes 9/10 mile every 30 minutes,or 1/2 hour. How many miles does she hike each hour?
9514 1404 393
Answer:
1.8 miles
Step-by-step explanation:
In the first half hour, Sandra hikes 9/10 = 0.9 miles. She hikes that distance again in the second half-hour. After an hour, Sandra has hiked ...
2 × 0.9 miles = 1.8 miles
__
If you like, you can consider it a "unit rate" problem. To find miles per hour, divide miles by hours:
(9/10 mi)/(1/2 h) = (9/10)(2/1) mi/h = 9/5 mi/h = 1.8 mi/h
Sandra hikes 9/5 or 1.8 miles in an hour.
Write the word sentence as an inequality. Then solve the inequality. Six times a number x is at least −24.
6x≥-24 is the inequality of sentence Six times a number x is at least −24 and x≥-4 is the solution of inequality.
What is Inequality?A relationship between two expressions or values that are not equal to each other is called 'inequality.
The given sentence is Six times a number x is at least −24.
Whenever there is a word times means it is a product.
Atleast means greater than or equal to.
Let x be the number in inequality.
Six times a number x is 6x.
Six times a number x is atleast −24.
6x≥-24
6x≥-24 is the required inequality
Divide both sides by 6
x≥-4
Hence, 6x≥-24 is the inequality of sentence Six times a number x is at least −24 and x≥-4 is the solution of inequality.

find area and perimeter
pls show work
Step-by-step explanation:
ok so first you can split the object into 2 different shapes like the first picture.
next you can start with shape labeled 1
and the perimeter of that would be 5+5+4+4 =14
so the perimeter is shape 1 is 14
the area would be5×4 which is 20
now shape 2 the perimeter of that would be 8+8+2+2 which is 20
the area would be 8×2 which would be 16
so then you add the are and perimeter of each shape together
p= 14+20=34
a= 20+16= 36
