Complete question :

Angela makes a pillow in the shape of a wedge to use for watching TV. The pillow is filled with 0.35 m3 of fluffy material, with base 0.5 m and height 1m

What is the length of the pillow?

Answer:

1.4 m

Step-by-step explanation:

The volume of wedge is given by:

V = Area of triangle * length

Area of triangle = 1/2 * base * height

Volume of wedge = 1/2 * base * height * length

Volume of wedge = 0.35m³

0.35 = 0.5 * 0.5 * 1 * length

0.35 = 0.25 * length

Length = 0.35 / 0.25

Length = 1.4 m

Answer:

1.4

Answer:

The submarine would be 179 feet below sea level

Step-by-step explanation:

m = 7

13 x 7 = 91

-270 + 91 = -179

After 7 minutes submarine was at -17 feet.

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.

Given that, the expression - 270+ 13m represents a submarine that began at a depth of 270 feet below sea level and ascended at a rate of 13 feet per minute.

A) Here, m=7

-270+13(7)

= -270+91

= -179

B) No

Therefore, after 7 minutes submarine was at -17 feet.

B. The submarine will have reached sea level after 7 minutes.

Answer:

The area of the base of a box is 1800 cm².

Step-by-step explanation:

We have:

H: is the height = 4 cm

[tex]A_{l}[/tex]: is the lateral surface area = 120 cm

L = 2B                                                                

We can find the breadth of the base by using the lateral surface area and the height:

[tex] A_{l} = H*B [/tex]        

[tex] B = \frac{A}{H} = \frac{120 cm}{4 cm} = 30 cm [/tex]

Now, if the length is twice its breadth we have:

[tex] L = 2B = 2*30 cm = 60 cm [/tex]

Hence, the area of the base is:

[tex] A_{b} = B*L = 60 cm*30 cm = 1800 cm^{2} [/tex]

Therefore, the area of the base of a box is 1800 cm².

Answer:

m = -1/2

Step-by-step explanation:

M is the slope. Y2-y1/x2-x1

Pick yep points (3,0) and (-1,2)

2-0/-1-3

2/-4

=-1/2

Answer:

To solve this you must first know how Log works.

When we say log1000 of base 10

Or

log1000=3

What we actually say is for the power 3(value on RHS) of 10(the base of log) we get 1000(the value on which log is performed).

So log2x=−5 (i am assuming base 10 since it is simple algebra) means that

2x=10−5

x=10−5/2

Do this simple calculation and you have it. If anything is unclear/incorrect feel free to comment.

The question is not written properly, so I will give the answer(s) I think would be suitable.

If you were trying to solve this

log2x=−5

⟹x=2−5

⟹x=132

But if you were trying to solve this

log2x=−5

⟹log102x=−5

⟹2x=10−5

⟹x=12×105=1200000

Answer:

x + 40

Step-by-step explanation:

Con la informacion de la pregunta vemos que Kelly tiene una cierta cantidad de plata ahorrada. Este ahorro se puede demonstrar con la variable x. Despues de completar su trabajo le pagaron $40 y los agrego a sus ahorros. Entonces simplemente tenemos que sumar los $40 a los ahorros que ya tenia (x). Esto nos dara la cantidad nueva de sus ahorros

x + 40

Answer:

x = 6√3

Step-by-step explanation:

Let's just look at the right triangle. This is a 30° 60° 90° triangle. The value of the large leg (x) will be the value of the small leg times √3. The value of the hypotenuse (12) is the value of the small leg times 2. Since we know that, we can divide 12 by 2 to find out the value of the small leg will be 6. Finally, know that we know that 6 is the value of the small leg, we can multiply 6 by √3 to find that the value of x = 6√3.

Answer: [tex]6\sqrt{3}[/tex]

Step-by-step explanation:

This is a 30-60-90 triangle because we know that there is a right angle and a 60 degree angle

the side opposite to 30 degrees is a, 90 degrees is 2a, and the side opposite to 30 degrees is [tex]a\sqrt{3}[/tex]

2a = 12 so a = 6 and  [tex]a\sqrt{3}[/tex] is [tex]6\sqrt{3}[/tex]

Answer: A 20% tip of $84.97 is $12.75 the total would then be    $97.72

Step-by-step explanation:

Answer:

p - p(.60)

Step-by-step explanation:

to find 60% of p you turn 60% into a decimal, which is .60, next you multiply .60 by p which will give you 60% off of p,

finally you take the total which is p and subtract off the discount which is .60p, thus p-p(.60)

also... another way to solve this is that if you are getting 60% off that means you are paying 40% of the price, thus you could just multiply p(.40) to get the amount the person would actually pay

Answer:

I think it is correct and is 1 and 2

Step-by-step explanation:

5×4^(x+1)-16^x=64

0=64+16^x-5×4¹×4^x

0=(4^x)²-2×4^x×10+10²-10²+64

0=(4^x-10)²-36

(4^x-10)²=36

4^x-10=√36

4^x=+-6+10

when positive

4^x=4²

:.x=2

when negative

4^x=4

Step-by-step explanation:

let n and n + 2 be 2 consecutive even numbers , then

(n + 2)² - n² ← is the difference

= n² + 4n + 4 - n²

= 4n + 4

= 4(n + 1) ← a multiple of 4

Answer:

  $503.85

Step-by-step explanation:

The amortization formula can help with this.

  A = P(r/12)/(1 -(1 +r/12)^(-n))

where P is the loan value, A is the monthly payment, r is the annual interest rate, and n is the number of monthly payments.

We want to find P. All of the other values are given.

  P = A(1 -(1 +r/12)^-n)/(r/12)

  P = 32.48(1 -1.012667^-18)/(0.012667) = 31.48·16.0054

  P ≈ 503.85

The equivalent cash price is about $503.85.

Answer:

7.35 Million

Step-by-step explanation:

So you already have the function and all you have to do is find the years.

p(t)=3.98(1.02)^t

I'm thinking that you should find the difference between 2021 and 1990. The answer would be 31 and just substitute that from t.

p(t)=3.98(1.02)^31

From here you would jut plug this function into your calculator and get a final answer of:

7.35 Million
