David drew this diagram of a picture frame he is going to make. Each square represents 1 square inch. What is the area of the picture frame?
Answer:
64 in²
Step-by-step explanation:
Find the area of the larger rectangle first, and then minus the area of the smaller rectangle.
The length of the larger rectangle
= 9-3 = 6 in
The width of the larger rectangle
= 17-1 = 16 in
The area of the larger rectangle
= 6×16
= 96 in²
The length of the smaller rectangle
= 8-4 = 4 in
The width of the smaller rectangle
= 13-5 = 8 in
The area of the smaller rectangle
= 4×8
= 32 in²
The area of the picture frame
= 96-32
= 64 in²

Write the equation of the line that passes through the points (4,1) and (-6,9). Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.
Answer:
Find the slope:

Answer:
78 ft squared
Step-by-step explanation:
To find the area of trapezoid, we could use this formula:
.5*height*(sum of bases)
We know both the base lengths. They are 10 and 16 ft.
The height can be found by looking at that right triangle whose base is (16-10) ft or 6 ft.
So we want to find the height which is opposite the 45 degree angle and we have the adjacent side's measurement of 6ft.
This has the tangent ratio written all over it since tangent of an angle is opposite side's measurement over adjacent side's measurement.
tan(45)=height/6
1=height/6
6=height
6ft=height
The answer is:
.5*height*(sum of bases)
.5*6 ft*(10 ft+16 ft)
3 ft(26 ft)
78 ft squared
Note: That one right triangle is an isosceles right triangle so we didn't need trigonometry.
Let’s say you want to play a new card game called Pokee. Every player is dealt 4 cards and everyone compares what hands they have to see who wins. Our job is to figure out what the hierarchy of the hands should be. Below is a list of several scoring hands that we wish to compare. For each hand, count how many hands of that type there are (include the expression you used to get that value) along with a simple explanation of how you got that expression. Assume a standard 52 card deck with 4 suits.
a) Presidential Flush (J, Q, K, Ace, all the same suit)
b) Straightish (4 consecutive cards)
c)Flushed (4 cards of the same suit)
d) House (Two pairs of different cards)

Han and Leila live 7 miles apart. They decide to start walking toward each other's houses at
the same time. Leila walks at a rate of 2.5 miles per hour and Han walks at a rate of 3 miles
per hour. How long will it take for them to meet?
2.5 + 3 = 5.5 total speed
7miles / 5.5 mph = 1.27 hours
Answer:
1.27 hours
Step-by-step explanation:
The first step in this process would be adding both rates of Leila and Han together. We know Leila walks at 2.5 miles per hour and Han at 3 miles per hour.
[tex]2.5 + 3 = 5.5[/tex]
We got our sum as 5.5, so now we must complete Step 2, which is the final step. We must divide 7 by 5.5.
[tex]7 / 5.5 = 1.2727...[/tex]
1.2727 ≈ 1.27
the answer to the Question is 1.27 hours.
I NEED HELP! Im trying to find the height of a cone. How do I do the problem and can someone explain it step-to-step?
Answer:
first the primerter then the area
Step-by-step explanation:
Answer:
The height of the cone is simple... here are the steps
Step-by-step explanation:
V= 1/3πr²h
V would be 1,398
π would be 3.14
r² 9.2x9.2
so the new equation is 1,398=1/3(3.14)(84.64)h
Now to get h all by itself multiply all in the equation... after divide by 1/3
1,398= whatever number xh
Now divide that whatever number by 1,398 and you find the height.
Hope this helps.
A block of sugar maple wood has a mass of 82.8 g and density of 0.69 g/cm3. The block is a rectangular prism with a length of 5 cm and a width of 4 cm. What is the height of the block of sugar maple?
Answer:
6
Step-by-step explanation:
I believe if you fallow the mathematical process of d=m/v you will get 6
The height of the block of the sugar maple from the rectangular prism is 6 cm.
What is the volume of a rectangular prism?The volume of a rectangular prism signifies the rectangular area enclosed by the prism. The equation used in calculating the formula for a rectangular prism can be expressed as:
V = length × width × height
From the parameters given:
mass of a sugar maple = 82.8 gThe density of the sugar maple = 0.69 g/cm³[tex]\mathbf{Desity = \dfrac{mass}{volume}}[/tex]
[tex]\mathbf{volume = \dfrac{82.8 g }{0.69 \ g/cm^3}}[/tex]
volume = 120 cm³
Using the previous equation for calculating the volume of a rectangular prism, we have:
120 cm³ = 5 cm × 4 cm × height
120 cm³ = 20 cm² × height
height = 120 cm³/20 cm²
height = 6 cm

A circle has a circumference of 37 millimeters. What is the circle's
radius? Use 3.14 for pi and round your answer to the nearest tenth.
Answer:
5.9
Step-by-step explanation:
To find radius from circumference you need to divide it by pie. So 37 divided by 3.14 is 11.7834394904. This is the diameter. Now divide it by 2, in this case it is 5.89171974522. When you round to the nearest tenth it gives you 5.9. Hope this Helps!

Give an example showing why one of the methods is not correct.
Answer:
Brandon's methot is not correct
for example: x=9 9×1/2=4.5
Here's why:
Let's use his method to find the square root of 36. That means we multiply 36 by 1/2 = 0.5 to get 36*0.5 = 18; however, 18 is not the square root of 36. We can see that 18*18 = 324. Instead, the square root of 36 is 6 because 6*6 = 36.
As another example, let's say we want to find the square root of 64. With Brandon's method, we would get to 64*0.5 = 32, but 32*32 = 1024. Ashley's method is correct and 8*8 = 64 shows that 8 is the square root of 64.
As a visual approach, think of a square with side lengths 8 feet each. The area would be 8*8 = 64 square feet. If you didn't know the side length, but you knew that the area was 64 square feet, then you could apply the square root operation to find the side length to be 8 feet (or you could effectively use Ashley's guess-and-check method to arrive at 8 feet). In short, the square root operation is the opposite of squaring a number. We consider these inverse operations.
Multiplying by 1/2 is the same as dividing by 2. Division is the opposite of multiplication, and division is not the inverse of squaring a number. It's just a coincidence that Brandon's method happened to work on the value 4. But as shown earlier, it doesn't work in general.
The number of cases of a new disease can be modeled by the quadratic regression equation y = -2x^2 + 40x + 8. What is the best prediction for the number of cases in year 15
Answer:
158 cases
Step-by-step explanation:
Given tbe quadratic regression model :
y = -2x^2 + 40x + 8
y = number of cases of a new disease
x = number of years
The predicted number of cases of a new disease in 15 years can be calculated thus ;
Put x = 15 in the equation ;
y = -2(15)^2 + 40(15) + 8
y = - 2 * 225 + 600 + 8
y = - 450 + 600 + 8
y = 158
158 cases

Responder:
R $ 1300
Explicação passo a passo:
Dado que :
Quantia depositada:
Primeiro depósito = $ 500
Segundo depósito = $ 350
Terceiro depósito = $ 450
O valor total depositado é a soma de todos os três depósitos feitos e constitui o saldo atual da conta.
Primeiro depósito + segundo depósito + terceiro depósito
$ (500 + 350 + 450)

Un guepardo está persiguiendo a una gacela que corre a 90km/h. Le separa de ella una distancia de 20 m y lleva una velocidad de 97km/h, que mantiene durante 9s. ¿Alcanzará a la gacela?
Answer:
the cheetah traveled 243 m, it could not catch up with the gazelle that traveled 245 m.
Step-by-step explanation:
Given that
Cheetah running at 90 km/h
Separated from a distance of 20 m
Now speed is 97 km/h
The time is 9 seconds
We need to find out whether it would catch up with the gazelle
For Gazelle
90 km = 90 × 1,000 = 90,000 m
1 h = 1 × (60 x 60) = 3600 s
Now
90,000: 3,600 = 25 m / s
For Cheetah
97 Km = 97 × 1000 = 97,000 m
1 h = 1 × (60 × 60) = 3600 s
Now
97 000: 3600 = 26.94 i.e. 27 m/s
e = 27 m /s × 9 s = 243 m
e = 25 m/s × 9 s = 225 m
Now
we have to add 20 m advantage to the gazelle.
So,
= 225 + 20
= 245 m
So based on the above calculation
the cheetah traveled 243 m, it could not catch up with the gazelle that traveled 245 m.

1. Q(4)
2.p(-4)
3.p(1/2)
Answer: 1. 79
2. 13
3. 7/4
Step-by-step explanation:
Q(x)=5x^2-1
Q(4)=5(4)^2-1
=5(16)-1
=80-1
Q(4) = 79
p(x)=x^2+x+1
p(-4)=(-4)^2+(-4)+1
=16-4+1
p(-4) =13
p(x)=x^2+x+1
p(1/2)=(1/2)^2+(1/2)+1
=1/4+1/2+1
2+4+8/9
=14/8
p(1/2) = 7/4
