Monica goes to a stationery shop to buy pens and pencils. She has $35 in pocket change, and she's looking to buy pens for $7 each and pencils for $2 each.
Write an inequality to describe the possible number of pens and pencils that Monica can buy. If Monica buys 3 pens, what is the maximum number of pencils she
can buy?
Answer:
7 pencils
Step-by-step explanation:
Let x equal the number of pencils Monica buys and y equal the number of pens.
The expression would then be 2x + 7y ≤ 35. Plugging in 3 for y:
2x + 7(3) ≤35
2x +21 ≤ 35
2x ≤ 14
x≤ 7

Jake is building a fence around his property. He wants the perimeter to be no more than 100 feet. He also wants the length to be at
least 10 feet longer than the width. If he builds his fence according to these limits, which would be the maximum possible width of
the fence?
Answer:
C
Step-by-step explanation:
Let the length be l and width be w.
The perimeter will be 2 lengths + 2 widths = 2l+2w
2l+2w cannot be more than 100ft
[tex]21+2w \leq 100[/tex]
Also, the length has to be at least 10ft longer than the width.
[tex]l\geq w+10[/tex]
If we substitute w=20, l=30. 2l+2w can be equal to 100 but not over it.
If w=20 and l=30, 2w+2l = 40+60 = 100.
Hence the maximum length of the width of the fence is 20 ft. C

What is the integer that is closer to the square root of 35
A right triangle is displayed.
The area of the right triangle is
A. 24 in ^2
B. 48 in ^2
C. 432 in ^2
D. 864 in ^2
Answer:
You have to use the Pythagorean Theorem to find the other side, which will be your base in the Area formula (A=1/2bh). So the Pythagorean theorem would be 36^2 + b^2 = 60^2. This gives you 48 in for your base/missing side length. Then, you plug it into the area formula. So, A=1/2(48) (36). This gives you 864 in^2 for the area of your triangle.

Haley has three times as many stuffed animals as she does dolls. Her brother has 15 more video games than Haley has stuffed animals. If Haley has 15 dolls, how many video games does her brother have? A. 228 B. 60 C. 33 D. 30
Answer:
60
Step-by-step explanation:
stuffed animals = 3 x dolls eqn 1
video games = 15 + stuffed animals eqn 2
dolls = 15
replace for dolls in eqn 1
stuffed animals = 15 x 3 = 45
substitute for stuffed animals in eqn 2
45 + 15 = 60

Answer:
5 inches
Step-by-step explanation:
Since the length irl is 60 yards you should divide 60 by 3.
60/3=20
Then convert 1/4 to a decimal.
1/4=0.25
Finally multiply 20 and 0.25 to get the length of the park on the map.
20x0.25=5

To find the average of some quantities , add them together and then divide the total by the number of
Answer:
quantities or total number of observations
Step-by-step explanation:
Average also known as mean is a measure of central tendency. It is determined by adding the numbers together and dividing it by the total number
Average = sum of the numbers / total number
For example, there are 3 numbers 3 , 6, 9
Average = ( 3 + 6 + 9) / 3 = 18 / 3 = 6

Hi!pls can u help me factorise this
50d^2 - 98e^2
Factor out 2.
2(25d^2 - 49e^2)
We now factor the difference of two perfect squares within the parentheses.
2(5d - 7e)(5d + 7e)
This is as far as we can factor.
Done!
The factor of the expression into an equivalent form 50d²- 98e² would be; 2(5d - 7e)(5d + 7e)
What is factorization?Factorization is the method of breaking a number into smaller numbers that multiplied together will give that original form.
Those expressions that might look different but their simplified forms are the same expressions are called equivalent expressions.
