The length of a picture frame is inches more than the width. For what values of x is the perimeter of the picture frame greater than inches?
9514 1404 393
Answer:
x > 35
Step-by-step explanation:
The perimeter is twice the sum of length and width. You want x such that ...
P > 156
2(x +(x+8)) > 156
4x +16 > 156 . . . . . simplify
x +4 > 39 . . . . . . . . divide by 4
x > 35 . . . . . . . . . . . subtract 4
The perimeter of the frame will be greater than 156 inches for x > 35.

Answer: It should be 24 because Ray SP is an angle bisector
Step-by-step explanation:
x=a+b+4 and a is inversely proportional to y²; b is inverseley propotional to 1/y. when y = 2 x = 18 and when y = 1 x = -3. find x when y = 4
Answer:
When y = 4, x is equal to 39
Step-by-step explanation:
The given parameters are;
x = a + b + 4
a ∝ 1/y²
b ∝ 1/(1/y) = y
When y = 2, x = 18
When y = 1, x = -3
Therefore, we have;
a·y² = j
a = j/y²
b ∝ 1/(1/y)
∴ b ∝ y
b = k·y
When y = 2, x = 18, we have;
a = j/y² = j/2² = j/4
b = k·y = k·2
x = a + b + 4
∴ 18 = j/4 + k·2 + 4...(1)
When y = 1, x = -3, we have;
a = j/y² = j/1² = j
b = k·y = k·1 = k
x = a + b + 4
∴ -3 = j + k + 4...(2)
Making 'j', the subject of equation (1) and (2) gives;
From equation (1), we have;
18 = j/4 + k·2 + 4
∴ j = (18 - 4 - k·2) × 4 = 56 - 8·k
From equation (2), we have;
-3 = j + k + 4
∴ j = -3 - 4 - k = -7 - k
Equating the two values of 'j', gives;
56 - 8·k = -7 - k
56 + 7 = 8·k - k
63 = 7·k
k = 63/7 = 9
k = 9
From equation (2), we get;
-3 = j + k + 4
k = 9
∴ -3 = j + 9 + 4
j = -3 - 9 - 4 = -16
j = -16
When y = 4, we get;
x = a + b + 4
a = j/y²
b = k·y
∴ x = j/y² + k·y + 4
Plugging in the values of 'j', and 'k' and y = 4, gives;
x = (-16)/y² + 9·y + 4
∴ x = (-16)/4² + 9 × 4 + 4 = 39
x = 39
Therefore;
When y = 4, x = 39.
find the measure of all of the angles on the diagram
Answer:
Angle 1: 135*
Angle 2: 45*
Angle 3: 45*
Angle 4: 135*
Angle 5: 135*
Angle 6: 45*
Angle 7: 45*
Angle 8: 135*
Step-by-step explanation:
So we have angle 2, 45*, we can subtract 45 from 180 to get the angle for 1. Since everything is the same size as either 1 or 2 we can just plug in the bigger angle number we have for it, ex 4= 135 and so is 7.
If you don't understand something please don't hesitate to ask.
Answer:
Step-by-step explanation:
∠2 = 45
∠3 = ∠2 {Vertically opposite angles}
∠3 = 45
∠7 = ∠3 {Corresponding angles}
∠7 = ∠45
∠6 = ∠7 {Vertically opposite angles}
∠6 = 45
∠1 + ∠2 = 180 {Linear pair}
∠1 + 45 = 180
∠1 = 180 -45
∠1 = 135
∠4 =∠1 {Vertically opposite angles}
∠4 = 135
∠8 = ∠4 {Corresponding angles}
∠8 = 145
∠5 = ∠4 {Alternate interior angles}
∠5 = 145
what ratios is equivalent to 6/7
Answer:
6:7
12:14
24:28
Step-by-step explanation:
The beginner ratio is 6:7 to find new equal ratios we just multiply both numbers by a number. In those, each of them is multiplied by two. You can multiply it by any number as long as you keep the 6's answer in the 6's spot and same for 7 & that you multiply both sides and not just one.

How does the denominator of the sum, 1 5/12, compare to the denominators of the addends, 2/3 and 3/4?
Answer:
There denominators are same, ie = 12
Step-by-step explanation:
Sum , 1 + 5/12 = (12 + 5) / 12
= 17 / 12
Sum , 2/3 + 3/4 = (8 + 9) / 12
= 17 / 12
Andrew and Sebastian are training for a weightlifting competition. In order to prepare, each of them has created their own personal training plan as follows:
• Andrew will start off by lifting 50 pounds and will increase the weight he lifts by 10% each week.
• Sebastian will start off by lifting 40 pounds and will increase the weight he lifts by 10 pounds each week.
Which of the following statements are true?
OOOOO
Andrew and Sebastian both increase the weight they lift each week by the same amount
Andrew's training plan can be modeled by a linear function, and Sebastian's training plan can be modeled by an exponential function.
Andrew's training plan can be modeled by an exponential function, and Sebastian's training plan can be modeled by a linear function.
Andrew increases the weight he lifts each week by equal factors, and Sebastian increases the weight he lifts each week by equal differences
Andrew increases the weight he lifts each week by equal differences, and Sebastian increases the weight he lifts each week by equal factors

A company makes 140 bags. 28 of the bags have buttons but no zips. 47 of the bags have zips but no buttons. 27 of the bags have neither zips nor buttons. How many bags have zips on them?
Answer:
95 bags have zips.
Step-by-step explanation:
140 - total bags
28 - buttons + no zips
47 - no buttons + zips
27 - no buttons + no zips
----
140 - 28 = 112
112 - 27 = 85

Answer: 4955.30
Step-by-step explanation:
F = P (1+i)^n
F = $4000 (1+.055)^4
F = $4955.2986
Which will be 4955.30
Answer:
A. $4955.30
Step-by-step explanation:
Look at the equation
A(t)= P(1+r)^t
In this equation,
A(t) is your amount after a period of time,
P is the initial balance stated in the question (4000)
r is the rate (must be converted to a decimal) as stated in the question (0.055)
t represents the amount of time that has passed (4 years)
Whenever you plug this into the equation, you get
A(t) = 4000(1.055)^4 and this can be plugged into a calculator to get your answer which will be
4955.29 (round up to .3) and your final answer is A. 4995.30
In order to convert from percent to decimal you just need to move the decimal to the left two places
5.5 becomes 0.055 after the decimal is shifted
Lewis checked the balance of his savings
account every month for 4 months. The
balances were $300, $410, $520, and
$630. Would a linear or exponential
function better represent the data?
Explain.
Answer:
Linear
Step-by-step explanation:
The balances each go up by $110
300 + 110 = 410
410 + 110 = 520
520 + 110 = 630

Show work, if possible. Thanks❤️
Answer:
I'm doing some of these questions now in my math class. I think it's D) 44 sorry if I'm wrong tho
Answer:
Step-by-step explanation:
Since the hypotenuse is 44 and the two sides are equal to FT we can say
2(FT)^2=44^2
FT^2=968
FT=22(2^(1/2))
So C is the correct answer.
