Solve for x: 2/5=4/x
9514 1404 393
Answer:
x = 10
Step-by-step explanation:
Using your number sense, you recognize that a fraction equivalent to 2/5 that has 4 in the numerator is 4/10. This tells you x = 10.
__
The usual instructions for solving this algebraically are to "cross multiply", then divide by the coefficient of x.
2/5 = 4/x . . . . given
2x = 20 . . . . . multiply by 5x on both sides
x = 10 . . . . . . . divide by 2
__
You can do the above two steps both at once: multiply by 5/2x.
(2/5)(5/2x) = (4/x)(5/2x)
x = 20/2 = 10
To make 3 litres of pale purple paint you mix:
1.5 litres red
1.25 litres of blue
0.25 litres of white paint.
a How much red paint is needed to make 8 litres of paint?
Answer:
We need 4 litres of red paint.
Step-by-step explanation:
We need to take their respective precentages to compare the 3 litres of paint to 8 litres of paint.
[tex] \frac{1.5}{3} \times 100\% = 50\% \\ \frac{1.25}{3} \times 100\% = 41.67\% \\ \frac{0.25}{3} \times 100\% = 8.33\% \\ [/tex]
Now, we know that the pale purple paint contains 50% red paint, 41.67% blue paint, and 8.33% white paint.
Now, we will transfer these percentages to the 8 litres of paint:
[tex]50\% \: of \: 8 \: litres = 0.5(8) = 4 \: litres \\ 41.67\% \: of \: 8 \: litres = 0.4167(8) = 3.3336 \: litres \\ 8.33\% \: of \: 8 \: litres = 0.0833(8) = 0.6664 \: litres[/tex]
PLZ HLP! A dog is leashed to the corner of a house. How much running area does the dog have? Round your answer to the nearest square foot, if necessary.
The area of a circle is area = pi x r^2
The full area = 3.14 x 20^2 = 1256 square feet.
The corner forms a 90 degree angle so the dirt area is 3/4 of a full circle.
Answer = 1256 x 3/4 = 942 square feet
Answer:

Arya deals in clothing and accessories. She bought 10 shirts at a wholesale price of 1120 each and sold them
all at a profit of 40 percent.
What was the price Arya charged for the 10 shirts?
Answer:
15680
Step-by-step explanation:
Cost of 1 shirt: 1120
Cost of 10 shirts: 11200
Add 40% to the cost of 10 shirts:
40% + 100% = 140% = 1.4
1.4 * $11200 = 15680
Answer: 15680
Which quadratic function is represented by the graph?
f(x) = 0.5(x + 3)(x − 1)
f(x) = 0.5(x − 3)(x + 1)
f(x) = 2(x + 3)(x − 1)
f(x) = 2 (x − 3)(x + 1)
Answer:
I believe the answer is f(x) = 0.5(x + 3)(x − 1)
Step-by-step explanation:
Answer: i think its f(x) = 0.5(x + 3)(x − 1)

Step-by-step explanation:
Trisha has $100 to spend on presents for 4 of her friends. She wants to spend the same amount on each friend. How much money can she spend on each friend (x)?
*Choose the inequality that best matches this scenario.
a. 4+x ≤ 100
b. 4x ≤ 100
c. x ÷ 100 ≥ 4
d. 100 - x ≥ 4
Answer:
B
Step-by-step explanation:
Trisha has $100. So she has to spend less than $100 or exactly 100 on her friends. The sign to represent this is ≤ ( the less than or equal to sign )
so if she has 4 friends and wants to spend x on each friend, she would spend a total of 4x on her 4 friends.
Remember that she has to spend less than or equal to $100. The equation to represent this is 4x ≤ 100

whats all the fractions that are eqvalent to 4/3
Answer:8/6,12/9
Step-by-step explanation:
The fraction 8/6 is equal to 4/3 when reduced to lowest terms. To find equivalent fractions, just multiply the numerator and denominator of that reduced fraction (4/3) by any interger number, ie, multiply by 2, 3, 10, 30... 8/6 is equivalent to 4/3 because 4 x 2 = 8 and 3 x 2 = 6 12/9 is equivalent to 4/3 because 4 x 3 = 12 and 3 x 3 = 9
Answer:
4/3 = 8/6 = 12/9 = 16/12
= 20/15 = 24/18 = 28/21 = 32/24
= 36/27 = 40/30 = 44/33 = 48/36
= 52/39 = 56/42 = 60/45 = 64/48
= 68/51 = 72/54 = 76/57 = 80/60
= 84/63 = 88/66 = 92/69 = 96/72
= 100/75 = 104/78 = 108/81 = 112/84
= 116/87 = 120/90 = 124/93 = 128/96
= 132/99 = 136/102 = 140/105 = 144/108
= 148/111 = 152/114 = 156/117 = 160/120
= 164/123 = 168/126 = 172/129 = 176/132
= 180/135 = 184/138 = 188/141 = 192/144
= 196/147 = 200/150 = 204/153 = 208/156
= 212/159 = 216/162 = 220/165 = 224/168
= 228/171 = 232/174 = 236/177 = 240/180
= 244/183 = 248/186 = 252/189 = 256/192
= 260/195 = 264/198 = 268/201 = 272/204
= 276/207 = 280/210 = 284/213 = 288/216
= 292/219 = 296/222 = 300/225 = 304/228
= 308/231 = 312/234 = 316/237 = 320/240
= 324/243 = 328/246 = 332/249 = 336/252
= 340/255 = 344/258 = 348/261 = 352/264
= 356/267 = 360/270 = 364/273 = 368/276
= 372/279 = 376/282 = 380/285 = 384/288
= 388/291 = 392/294 = 396/297 = 400/300

If the shortest side of a right triangle is 19, what are the lengths of the other TWO sides
that makes the side lengths a Pythagorean triple? HELP ASAP PLZ
Answer:
180 and 181
Step-by-step explanation:
A pythagorean triple basically refers to numbers that satisfies the pythagorean theorem. This theorem states that the square of the hypotenus (a) of a right angle triangle is equal to the sum of the squares of the other two sides (b and c).
That is;
a² = b² + c²
If the shortest side is 19, the other two sides are 180 and 181.
The hypotenus is the longest side of the right angle triangle.
Check:
181 = 180 + 19
181² = 180² + 19²
32761 = 32400 + 361
32761 = 32761
