Which numbers between 10 and 99 have digits that differ by 4 and add to 6

Answers

Answer 1

Answer:

A

Step-by-step explanation:

Correct option is A)

Let a 3-digit number ABC

Case (1)

If A=7, then B  and  C can be any digit but not 7

so, total 9 digits (0,1,2,3,4,5,6,8,9) can replace B and C

Then total such combinations =1(9)(9)=81

Case (2)

If B=7  then A can be any digit but not  0 and 7, because if A=0 it will be a 2-digit number.

And C can be any digit but not 7

Then total combinations =(8)(1)(9)=72

Case (3)

If C=7  then A can be any digit but not 0 and 7, because if A=0 it will be a 2-digit number.

And B can be any digit but not 7

Then total combinations =(8)(9)(1)=72

So, total numbers between 99 and 1000 which have exactly one of their digits as 7 are =81+72+72=225

Please find the surface area of the prism... I will mark you brainliest

Answers

the surface area is 548 in^2

Answer:

The surface area = 548 in²

Step-by-step explanation:

The surface Area = 2lw + 2lh + 2wh  using l = 10 in, w = 7 in, and h = 12in.

Substitute into the formula and solve

  2lw + 2lh + 2wh

= 2· 10·7 + 2· 10 · 12 + 2 ·7 ·12

=  140  +  240 + 168

= 548 in²

A park charges $16 for one round of miniature golf and a reduced fee for each additional round played. If Tom paid $51 for 6 rounds of miniature golf, what is the reduced fee for each additional round played?

Answers

7 dollars each game and I know that because 10 would be 60 plus 16 which is way over and 5 would be 25 plus 16 which is incorrect 6 would be 30 which adding 16 would be 46. FINALLY ADDING 5 extra which is 7 times which is 35 plus 16 is 51.

A taxi charges a flat rate of $7.50 plus an additional $0.35 per mile. If Aliana has at most
$25 to spend on the cab ride, how far could she travel?
She could travel

Answers

Answer:

17.85 answer

Step-by-step explanation:

u add the following and the ans u get u take it away from 25

The inequality representing the given statement is 25 ≥ 7.5 + 0.35 x and Aliana can travel a total of 50 miles.

What is inequality?

An inequality is a relation that compares two numbers or other mathematical expressions in an unequal way. It is most frequently used to compare the sizes of two numbers on the number line.

Given:

A taxi charges a flat rate of $7.50 plus an additional $0.35 per mile,

Aliana has at most $25 to spend on the cab ride,

Write the equation as shown below,

The total charges of the taxi = flat rate + rate per mile × number of mile

The total charges of the taxi = 7.5 + x × 0.35

Here, x is the number of miles

The total charge should be equal to $25 or less than $25 then,

25 ≥ 7.5 + 0.35x

Solve for x

0.35x = 25 - 7.5

x = 17.5 / 0.35

x = 50 miles

Thus, she can travel a total of 50 miles.

Step-by-step explanation:

First, combine all the numbers in the square root, and then square root the number provided:

√(3 + 3 + 3 + 3 + 3 + 3) = √18

When square rooting, first, find prime factors of the number, 18. If there are pairs, they will be combined into a whole number:

√18 = √(3 * 3 * 2) = 3√2

3√2 is your answer.

The diagram shows a square pizza box with side lengths of 12 inches. In the box is a circular pizza with a radius of 5 inches. What is the difference between the area of box and the pizza?

Use π = 3.14 and round your answer to the nearest hundredth.

Answers

Nevermind give the points to the another guy

Step-by-step explanation:

the area of the box (as a square) is

side length × side length = side length ²

that is here 12² = 144 in²

the area of a circle is

pi×r²

that is here

pi×5² = pi×25 = 3.14×25 = 78.50 in²

the difference is

144 - 78.5 = 65.50 in²

Answers

Answer:

42°

Step-by-step explanation:

8 is the opposite

12 is the hypotenuse

We know from SOHCAHTOA to use sine

Since we are looking for the angle, we use sin^-1

sin^-1(opposite/hypotenuse)=x

sin^-1(8/12)=x

Input into calculator

x=42°

Step-by-step explanation:

we use the law of sine :

a/sin(A) = b/sin(B) = c/sin(C)

where the the side and related angle are always opposite to each other.

so,

12/sin(90) = 8/sin(x)

12/1 = 8/sin(x)

12 = 8/sin(x)

3 = 2/sin(x)

sin(x) = 2/3

x = 41.8103149...° ≈ 41.8°
