Answer:

21:8

Step-by-step explanation:

<u>Given information:</u>

Lori (x) is 8 years old.

In 5 years (x + 5), Philip will be twice Lori's age (y + 5 = 2(x + 5))

<u>The missing value, y, is needed to find the ratio for Lori's and Philip's ages in the present. To find y, solve this equation:</u>

y + 5 = 2(x + 5)   First, distribute the 2 into x + 5.

y + 5 = 2x + 10   Next, isolate the variable y by subtracting 5 from both sides.

y = 2x + 5           After that, add in the value of x, 8.

y = 2(8) + 5         Finally, simplify the right side to find Philip's age.

y = 16 + 5

y = 21

<u>Now for the easiest part: The ratio of Philip's age now to Lori's age now.</u>

because 21 is not divisible by any of 8's factors, the current ratio of 21:8 cannot be simplified further.

So, the ratio is 21:8

A roof is shaped like a square pyramid. The base length is 10 meters and the slant height is 12 meters. What is the surface area
nasty-shy [4]

Surface area of square pyramid having square base side = 10 cm and slant height = 20 cm is 340 square meters

<u>Solution:</u>

Given that  

Shape of the roof is square pyramid.

Base length of square pyramid roof = 10 meters

Slant height of square pyramid roof = 12 meters

Need to calculate the surface area of the roof

\text { Surface area of square pyramid }=s^{2}+2 \times s \times l

Where s is side of square base and l is slant height.

In our case s = 10 meters and l = 12 meters

On substituting the given values in formula we get  

Surface area of square pyramid =10^{2}+(2 \times 10 \times 12)=100+240=340 \text { meters }^{2}

Hence surface area of square pyramid having square base side = 10 cm and slant height = 20 cm is 340 square meters.

Is there any positive number b so that the expression logb (0) makes sense? Explain how you know?
topjm [15]

Answer:

No.

Step-by-step explanation:

The logarithm of a number to the base b of a certain number  is the exponent

to which the base b is raised to equal the given value.

So say we have  logb y = a, then

y = b^a

So if y = 0 then

0 = b^a

If b is a positive number then there is no value of a that makes y = 0.

for example y = b^0 = 1, y = b^1 = b  etc.

Find the nth term for the sequence 6 12 22 36 54
MissTica
It’s 76 because 6+6=12 and 12+10=22 so if you add 4 to the last one and you add the last number you get the next one. So, 22+14= 36 36+18= 54 so 18+4= 22 and 22+54= 76. Hope it helps!
