In the number 9663 which places contain digits where one dogit is 10 times as great as the other?
Answer: Hundreds and tens place values (the two copies of '6')
Explanation:
We're looking for where the digits are the same, which would be those two copies of '6'
The first 6 on the left is in the hundreds place. It represents 600
The other 6 is in the tens place, and it represents 60
The jump from 60 to 600 is "times 10".
10. What is the measure of angle y?
Answer:
50°
Step-by-step explanation:
Angles in a triangle always add up to 180°.
The square (bottom left of triangle) is a right angle and right angles always equal 90° and the other one is 40°, so you would add them up. This equals 130°.
To find y, you would have to do 180° minus 130° which is 50°.
Hope this helps :)

Step-by-step explanation:
a sequence starts a 200 and 30 is subtracted each time 200,170,140 what are the first two numbers in the sequence that are less
then zero
Answer:
- 10, - 40
Step-by-step explanation:
200, 170, 140, .... - 10, - 40 ....
30 × 5 = 150
140 - 150 = - 10
- 10 - 30 = - 40

(100/x)/100 = 1/x
but the question is HOW
how does this work algebraically?
Answer:
1/x
Step-by-step explanation:
(100/x)/100
100/x ÷ 100
Copy dot flip
100/x * 1/100
Rewriting
100/100 * 1/x
1 * 1/x
1/x
Answer:
Step-by-step explanation:
Use KCF for fraction division
Keep the first fraction.
Change division to multiplication
Flip the second fraction.
[tex]\frac{100}{x}[/tex] ÷ x = [tex]\frac{100}{x}*\frac{1}{100} = \frac{1}{x}[/tex]
3. Write y = x2 - 4x + 6 in vertex form.
A. y = (x - 2)2 + 2
B. y = (x + 2)2 - 2
C. y = (x + 2)2 - 4
D. y = (x - 2)2 + 4
Answer:
A.
[tex]y = (x - 2 {)}^{2} + 2[/tex]
Step-by-step explanation:
[tex]y = {x}^{2} - 4x + 6[/tex]
[tex] = y + 4 = {x}^{2} - 4x + 4 + 6[/tex]
[tex] = y + 4 = (x - 2 {)}^{2} + 6[/tex]
[tex] = y = (x - 2 {)}^{2} + 6 - 4[/tex]
[tex] = y = (x - 2 {)}^{2} + 2[/tex]
Identify a transformation of the function f(x) = _x by observing the equation
of the function g(x) = x+1.
Answer:
2nd option
Step-by-step explanation:
Given f(x) then f(x) + c is a vertical translation of f(x)
• If c > 0 then a shift up of c units
• If c < 0 then a shift down of c units
Here g(x) = [tex]\sqrt{x}[/tex] + 1
The base graph f(x) has been shifted up 1 unit

What is the measure of angle x?
Answer:
93+52+x=180(sum of angels of a triangle)
145+x=180
x=180-145
x=35
Answer:
D. 35
Step-by-step explanation
Every triangle equals to 180 degrees
Add the 2 angles, 93 and 52 which equals 145
Now subtract 180 and 145
Therefore, you should get 35

Answer:
34 : 6800000
Step-by-step explanation:
1 : 20000034km : ?34km : 34km × 20000034km : 6800000km34 : 6800000If a change dispenser contains 32 coins consisting of
only dimes and quarters worth $5.15, how many
dimes are in the dispenser?
=================================================
Work Shown:
d = number of dimes
q = 32-d = number of quarters
$5.15 = 515 cents
10d+25q = 515
10d+25(32-d) = 515
10d+800-25d = 515
-15d+800 = 515
-15d = 515-800
-15d = -285
d = -285/(-15)
d = 19
There are 19 dimes. You can stop here if you want.
q = 32-d = 32-19 = 13
There are 13 quarters
-------------------------------
Check:
1 dime = 10 cents
19 dimes = 19*10 = 190 cents
1 quarter = 25 cents
13 quarters = 13*25 = 325 cents
total value = 190 cents + 325 cents = 515 cents = $5.15
The answer is confirmed.

If x +5 = 2b, find 2x + 10 in terms of b.
Answer:
2x+10=4b
Step-by-step explanation:
If you look at the previous equation, you will notice that
x*2 = 2x and
5*2 = 10.
So now all you need to do is also multiply the right side of the equation with b by 2, just like you did to the left side, and you'll get
2x+10 = 4b.
I hope this helped! :D
Answer:
2x + 10 = 4b
Step-by-step explanation:
Given
x + 5 = 2b ( multiply through by 2 )
2x + 10 = 4b
What is the value of x?
Answer:
The triangles are similar, therefore the ratio of 2:1 is constant for all sides as shown in 20:10.
Therefore, x is 14.
Can someone please help me I don’t know how to do this (Due today)
First go to the y intercept (or the b in y=mx+b) look for the slope and plot the points on the graph they're talking about e.g. #23 the y-intercept is 6 go to the 6 on the y axis, and then look at the slope (x), so it goes up and over to the right since it's positive by 1
Solving just for X. Please help and thank you:)
Franco made a dozen muffins for his party upon taking them out he noticed two of the muffins were badly burned Franco served 7/
10 of the remaining muffins which Equation shows the fraction of the non-burned muffins that remain.
Total muffins = 12
Burned muffins = 2
not burned = 10
Total served = 7/10
= 7 muffins
So
10 - 7/10
3 unburned muffins left
Fraction = 3/10

The cardinality of the set of positive integer is infinity. (True or False)
Answer:
It is false, because infinity is not a cardinality. The set N of positive integers is infinite and its cardinality is, if you wish, ℵ0 , the smallest infinite cardinal number, at least in an axiomatic set theory. A set S is infinite if and only if there exists a bijection between S and a proper subset of S , i.e. a subset of S different from S . Now the successor function s:N→N∗ is such a bijection; this follows from Peano’s axioms for arithmetic.
Answer: false

What digit placed in the blank would make the number 138_ divisible by both 4 and 5
Answer:
The digit that should be placed in the blank is 0.
Step-by-step explanation:
We are given the four-digit number: 138_
And we want to determine the digit that should be placed in the blank to make the number be divisible by both 4 and 5.
A number that is divisible by 5 must end in either 0 or 5. This leaves us with only two options: 1380 or 1385.
Recalling divisibility rules, for a number to be divisible by 4, its last two digits must be divisible by 4.
80 is indeed divisible by 4, while 85 is not.
In conclusion, the digit that should be placed in the blank is 0, with the number being 1380.

A boy is flying a kite from the terrace of his house. The kite is 175 m above the terrace. If the terrace is 80 m from the ground floor, findthe distance between the kite and the basement which is 8 m below the ground level.
175 m above the terrace + 80 m from terrace to ground + 8m from ground to basement:
175 + 80 + 8 = 263 meters

Someone help please With geometry
Answer:
9
Step-by-step explanation:
RT = ST + RS
RT = x + 5, ST = 4x - 9, RS = x - 2
x + 5 = 4x - 9 + x - 2
Combine like terms
x + 5 = 5x - 11
Add 11 to both sides
x + 16 = 5x
Subtract x from both sides
16 = 4x
Divide both sides by 4
4 = x
Find RT
RT = x + 5
x = 4
RT = 4 + 5
RT = 9
Answer:
RT = 9
Step-by-step explanation:
R x - 2 S 4x - 9 T
+-------------------------------+--------------------------+
x + 5
RT = RS + ST
x + 5 = x - 2 + 4x - 9
x + 5 = 5x - 11
-4x = -16
x = 4
RT = x + 5
RT = 4 + 5
RT = 9
