Answer:
(3 1/2 ft.) / 5/8 in.
Step-by-step explanation:
both values must be in same increments; change feet to inches
3 1/2 ft = 7/2 ft
(7/2) 12/1 = 42 in.
Then: 42 / (5/8)
42 (8/5)

Solve for x. Round to the nearest tenth, if necessary.
Answer:
since the adjacent is given which is 6.3 and we are to solve for the hypotenuse, it's best to use Cos
since Cos(27°)=adjacent/hypotenuse
we can substitute in the values
therefore we have Cos(27°)=6.3/x
x=6.3/Cos(27°)
x=7.06...
rounding this to the nearest tenth will be 7.1
therefore x=7.1

lesser x =
greater x =
Answer:
lesser x = - 1 , greater x = 1
Step-by-step explanation:
- 4x² - 7 = - 11 ( add 7 to both sides )
- 4x² = - 4 ( divide both sides by - 4 )
x² = 1 ( take square root of both sides )
x = ± [tex]\sqrt{1}[/tex] = ± 1
then
lesser x = - 1

Nathan and some friends are going to the movies. At the theater, they sell a bag of
popcorn for $4.50 and a drink for $4.25. How much would it cost if they bought 7
bags of popcorn and 3 drinks? How much would it cost if they bought p bags of
popcorn and d drinks?
Answer:
$44.25
Step-by-step explanation:
($4.50×7)+(4.25×3)
=$31.50+$12.75
=$44.25
$44.25 is the cost if they bought 7 bags of popcorn and 3 drinks and 4.50p+4.25d is for p bags of popcorn and d drinks.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that
popcorn for $4.50
drink for $4.25.
There are 7 bags of popcorn and 3 drinks.
So let us find the total cost.
7(4.50)+3(4.25)
31.5+12.75
44.25
So $44.25 is the cost if they bought 7 bags of popcorn and 3 drinks
Now we need to find cost for p bags of popcorn and d drinks.
4.50p+4.25d
Hence $44.25 is the cost if they bought 7 bags of popcorn and 3 drinks and 4.50p+4.25d is for p bags of popcorn and d drinks.

4. Find the surface area of the triangular prism:
5 ft
5 ft
3 ft
14 ft
8 ft
Shows work please
Answer:
276ft^2
Step-by-step explanation:
A triangular prism is made up of multiple faces, just like any three-dimensional shape. Let's do the calculations for this shape together.
Top two faces: 5ft × 14ft × 2 = 140ft^2 (we multiply by two b/c there are two rectangles, so we save a step)
Front and back face: 8ft × 3ft = 24ft^2 (we do not divide by two b/c there are two triangles, so we save a step)
Bottom face*: 8ft × 14ft = 112ft^2
*Note: Don't solve for this face when calculating latent surface area, or when calculating the SA of a compound shape.
Now, we just add up the areas of all the shapes.
140 + 112 + 24 = 276
Final answer: 276ft^2

If Kelly's mom is 35, it will take her 15 more years to become 50. Make an equation to represent this.[tex]35 + 15 = 50[/tex]
Next, you want to add 15 to Kelly's age because for each year her mom ages, she ages for that same number of years.[tex]13 + 15 = 28[/tex]

The measure of angle L is 52
Step-by-step explanation:
Mathematically, in a triangle, the sum of the angles equal 180
So in this case;
J + K + L = 180
So therefore;
8x + 6 + 2x + 2 + 4x + 4 = 180
8x + 2x + 4x + 6 + 2 + 4 = 180
14x + 12 = 180
14x = 180 -12
14x = 168
x = 168/14
x = 12
So to get the measure of angel L, we simply substitute the value x in the equation for L
From the question, L = 4x + 4
So therefore L = 4(12) + 4 = 48 + 4 = 52
Triangle is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
Example:
Triangle ABC:
m∠A + m∠B + m∠C = 180
We have,
ΔHIJ
m∠H = x - 1
m∠I = 2x + 5
m∠J = 7x + 6
We know that,
The sum of the angles of the triangle is 180 degrees.
m∠H + m∠I + m∠J = 180
(x - 1) + (2x + 5) + (7x + 6) = 180
x - 1 + 2x + 5 + 7x + 6 = 180
10x + 10 = 180
Take 10 common.
10 (x + 1) = 180
Divide both sides by 10.
x + 1 = 180/10
x + 1 = 18
Subtract 1 on both sides.
x = 18 - 1
x = 17
Thus,
If in ΔHIJ,
m∠H = x - 1
m∠I = 2x + 5
m∠J = 7x + 6.
The value of x is 17.

Help asap no links pls
……….
Step-by-step explanation:
I will take long to answer this so i will give you the key to answering it.
Basically, since you know the sum of all the angles of a triangle equal 180, all you have to do is use 180 and subtract the numbers alredy there together to get the missing amount.
For example, to find out the answer to A, you already know two of the degree measurements which are 72 and 68. Now, subtract them with 180.
72+68=140
180-140=40
So, therefore, A equals 40 degrees.
I will give you one more example.
If you want to find the measurements of the angles B and C, the same process will happen. The only thing that is different is that only one known measurement is provided which is 36.5 but not so fast, they gave you a hint. That square above B. That means B is a right angle. So we got one measurement in the triangle, B is 90 degrees. Alright now continue like before.
90+36.5=126.5
180-126.5=53.5
Hope this helps.
