Answer:
[tex]h = 8 \: ft[/tex]
Step-by-step explanation:
Height of trapezoid formula:
[tex]h = 2 \times \frac{area}{a + b} [/tex]
Given:
Area: 40 square feet
a: 6 feet
b:4 feet
Using the given information,
[tex]h = 2 \times \frac{40}{6 + 4} [/tex]
Add the numbers in the denominator
[tex]h = 2 \times \frac{40}{10} [/tex]
Reduce the fraction with 10
[tex]h = 2 \times 4[/tex]
Answer:
[tex]h = 8 \: feet[/tex]

Answer:y = 10.5
Step-by-step explanation:
First, assign a variable to each unknown value.
Let:
x = cost of the pepperoni pizza
y = cost of the plain pizza
Next, set up equations based on the word problem. We then have the following equations:
(1) 3x + 2y = 58.50
(2) 2x + 4y = 67
Equation (1) comes from the statement: "Jack paid 58.50 for 3 pepperonies and 2 plain pizzas". Equation (2), on the other hand, translates the statement: "Jill paid 67 for 2 pepperonies and 4 plain pizzas".
To solve for two unknown variables given two independent equations, eliminate one variable first. That is, multiply equation (1) to -2.
-2[3x + 2y = 58.50]
-6x -4y = -117
Then add this to equation (2):
-6x -4y = -117
2x + 4y = 67
-------------------
-4x = -50
x = -50/-4 = 12.5
To solve for y, we use equation (2) and substitute the value of x which has been solved already.
2(12.5) + 4y = 67
y = 10.5
To summarize, they paid $12.50 for the pepperoni pizza while they paid $10.50 for the plain pizza.

Insight number 2: to evaluate the limit of a:
1. Rational function: you can factorize and cancel out what you can
2. Radicals (subtractions of square roots): multiply and divide by the
conjugate. For example:
Vx2 + 1 - x
x? +1 - x2
x2 +1-x=
(V x2 +1 + x)
Vx2 + 1 + x
V.x2 + 1 + x
1
Vx2 +1 + x
3. Trigonometric functions: try to connect your limit with important
sin (x)
trigonometric limits like limx40 = 1
If you are stuck with a trig limit, express all the trig functions in terms
of sine and cosine.
4. If you are composing continuous functions, you can pass the limit
inside the external function: Cimz-a f(g(x)) = f(lim,-a 9(x))

In a survey of 1.400 people who owned a certain type of car, 980 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
Answer:
Percent of people satisfied with the car = 70%
Step-by-step explanation:
Given:
Total number of people survey = 1,400
Number of people satisfied with the car = 980
Find:
Percent of people satisfied with the car
Computation:
Percent of people satisfied with the car = [Number of people satisfied with the car / Total number of people survey]100
Percent of people satisfied with the car = [980 / 1400]100
Percent of people satisfied with the car = 70%
In ΔQRS, RS = 16, SQ = 9, and QR = 15. Which list has the angles of ΔQRS in order from smallest to largest?
Answer:
[tex] \angle R < \angle S < \angle Q[/tex]
Step-by-step explanation:
In ΔQRS, RS = 16, SQ = 9, and QR = 15.
From above info it is obvious that:
SQ < QR < RS
In a triangle, angle opposite to smallest side is smallest and angle opposite to largest side is largest.
Therefore,
[tex] \angle R < \angle S < \angle Q[/tex]

Andrés va a colocar piso
a su cuarto, si el cuarto mide
3.7m de ancho por 4.5m de
largo y cada caja de piso
alcanza para 1.54m2. ¿Cuántas
cajas de piso va a necesitar?
Responder:
11
Explicación paso a paso:
Dado que:
Dimensión de la habitación = 3,7 m por 4,5 m
Área de la habitación:
Largo * ancho
Los 3.7m * 4.5m
= 16,65 m²
Área de la caja de piso = 1.54m²
Número de cajas de suelo necesarias:
Área de la habitación / área de la caja de piso
16,65 m² / 1,54 m²
= 10,812
= 11 cajas de suelo

Problem 1) 25 milesProblem 2) 3 hoursProblem 3) They are cycling the fastest from 10:00 a.m. to 10:30 a.m.============================================================
Explanations:
The vertical axis, aka y axis, tells us how many miles are traveled. The highest it goes is y = 25, which is the number of miles traveled. They reach this marker at 1:00 p.m.The timespan from 10:00 a.m. to 12:00 p.m. is 2 hours (since 12-10 = 2). Then from 12:00 p.m. to 1:00 p.m. is an extra hour. In total, they traveled for 2+1 = 3 hours.They are cycling the fastest when the distance/time graph is steepest. Recall that the slope represents the speed when x is the time and y is the distance. This is because speed = distance/time. Apply the slope formula to the various different pieces and you should find the slope is largest from 10:00 a.m. to 10:30 a.m. The speed here is 20 mph. The next section has a speed of 10 mph. They then take a rest from 11:30 a.m. to 12:00 noon due to the flat horizontal portion here. The last section has a speed of 5 mph.If a1=1 and an+1=ann+2 for n≥1, determine a1,a2,a3, and a4
Answer:
a1 =1
a2= 1/3
a3= 1/12
a4 = 1/60
Step-by-step explanation:
a(n+1) = an/(n+2)
if n=1
a(1+1)= a1/(1+2)
a2= a1/3
a2= 1/3
if n=2
a(2+1)= a2/(2+2)
a3= a2/4 = a2 × 1/4
a3= 1/3 × 1/4 = 1/12
if n=3
a(3+1)= a3/(3+2)
a4= a3/5 = a3 × 1/5
a4= 1/12 × 1/5 = 1/60
The value of [tex]\rm a_{1}, \rm a_{2}, \rm a_{3}, \rm a_{4}[/tex] for a given expression [tex]\rm a_{n+1} = {\frac {a_{n}} {n+2}[/tex] is 1, 1/3, 1/12, and 1/60.
We have given [tex]\rm a_{1} =1[/tex] and [tex]\rm a_{n+1} = {\frac {a_{n}} {n+2}[/tex] for n≥1 we need to determine the value of [tex]\rm a_{1}, \rm a_{2}, \rm a_{3}, \rm a_{4}[/tex] .
How do you solve for n terms?To solve for n terms, we will substitute the value of n = 1,2,3,4 and so on sequence-wise in the given expression.
if n = 1
[tex]\rm a_{1+1} = {\frac {a_{1}} {1+2}[/tex]
[tex]\rm a_{2} = {\frac {a_{1}} {3}}\\\rm a_{2} = {\frac{1} {3}[/tex]
if n = 2
[tex]\rm a_{2+1} = {\frac {a_{2}} {2+2}}\\\rm a_{3} = {\frac {1/3} {4}}\\\rm a_{3} = 1/12[/tex]
if n = 3
[tex]\rm a_{3+1} = {\frac {a_{3}} {3+2}}\\\rm a_{4} = {\frac {a_{3}} {5}}\\\rm a_{4} = 1/12 \times 1/5\\\rm a_{4} = 1/60[/tex]
So, the value of [tex]\rm a_{1}, \rm a_{2}, \rm a_{3}, \rm a_{4}[/tex] is 1, 1/3, 1/12, and 1/60.

A number
consisting of
two digits whose sum is 9.
If three times the number is
equal to eight times the
number formed by interchanging
the digits, find the number.
Answer:
let the unit digit be x
and the tens digit be y
so x+y = 9 ---> y = 9-x
the number is 10y+x
the number reversed is 10x + y
3(10y+x) = 8(10x + y)
30y + 3x = 80x + 8y
22y = 77x
2y = 7x
2(9-x) = 7x
18 - 2x = 7x
18=9x
x=2
y=7
the number is 72
check:
number is 72
reverse is 27
is 3(72) = 8(27)

Answer:
[tex]y=-x-4[/tex]
Step-by-step explanation:
Since we already know that the slope is [tex]-1[/tex] we can use this formula to solve for the y-intercept: [tex]b=y-mx[/tex]
b is the y-intercept

Would y^10/y^10 become 1?
Answer:
yes
Step-by-step explanation:
If you are dividing it will become 1 because 10 minus 10 equals 0. Anything to the power of 0 is 1 then you keep the base which is y so the answer is y
If you are multipling the answer will be y^10 because 10 plus 10 is 20 and you keep the base which is y
