The ratio of boys to girls in the sixth grade is 2:3
1)If there are 24 boys, how many girls are there?
2)If there are 80 students, how many are girls?
Answer:
3*16=48 girls (further explination below)
Step-by-step explanation:
80/(2+3)=16, so since 3 in the ratio is for girls, there are 3*16=48 girls.

True Or False The Solution to an equation is the ONE number that makes it true.
Answer:
True.
Step-by-step explanation: If you substitute the solution into the original equation, it is the only number that will make the equation balanced or have an equal value on both sides of the equals sign.
If an Australian contractor ordered $340,000 U.S. Dollars worth of steel from an American company, what is the cost of the steel in Australian dollars? (Enter a number as an exact integer or decimal.)
Answer:
466895
Step-by-step explanation:
If you know the conversion, it's easy.
1 US dollar is about 1.37322 Australian.
so, you multiply 340,000 times 1.37322 and get about 466895 Australian dollars
Construct a frequency distribution and a frequency histogram for the data set using the indicated number of classes. Describe any patterns. Number of classes: 8 Data set: Finishing times (in seconds) of 20 male participants in a 5K race
Answer and Explanation:
Number of classes = 8
Highest value =2300
Lowest value = 1250
Class width= highest value – lowest value / number of classes
= 2300 – 1250/8
= 131.25 = 132
So, we can write class as 1250+132=1382
Class frequency
1250-1382 2
1382-1514 3
1514-1646 6
1646-1778 2
1778-1910 3
1910-2042 2
2042-2174 1
2174-2306 1

please hurry!! the graph of y= 2/x - 1 is shown which statement about the graph is accurate
A. the x-intercept or the graph (2, 1)
B. the graph has no y-intercepts
C. the y-intercept of the graph is (2, 0)
D. the graph has no x-intercepts
Answer:
B. The graph has no y-intercepts
Step-by-step explanation:
We see that we have vertical and horizontal asymptotes.
We also see that the right side of the graph has an x-intercept of (2, 0).
Therefore, A and D are incorrect.
We use the vertical asymptote x = 0 to get our answer B, as we will never cross the y-axis as x approaches negative and positive infinity.
what is the answer to 19=-3a-5
Answer:
[tex] \fbox{ \huge{ \sf{ a = - 8}}}[/tex]
Step-by-step explanation:
[tex] \bigstar{ \sf{ \: 19 = - 3a - 5}}[/tex]
[tex] \tt{Step \: 1 \: }[/tex] : Swap the sides of the equation
[tex] \longmapsto{ \sf{ - 3a - 5 = 19}}[/tex]
[tex] \tt{Step \: 2 \: }[/tex] : Move 5 to right hand side and change it's sign
[tex] \longmapsto{ \sf{ - 3a = 19 + 5}}[/tex]
[tex] \tt{Step \: 3 \: }[/tex] : Add the numbers : 19 and 5
[tex] \longmapsto{ \sf{ - 3a = 24}}[/tex]
[tex] \tt{Step \: 4 \: }[/tex] : Divide both sides by -3
[tex] \longmapsto{ \sf{ \frac{ - 3a}{ - 3} = \frac{24}{ - 3}}} [/tex]
[tex] \tt{Step \: 4}[/tex] : Calculate

Solve for h
3/7=h/14-2/7
Answer:
h =10
Step-by-step explanation:
3/7 = h/14 -2\7
3/7 = 1/14 h + -2/7
1/14 h + -2/7 = 3/7
1/14 h + -2/7 +2/7 = 3/7 + 2/7
1/14 h = 5/7
14 * ( 1/14h) = 14* (5/7)
h =10
please help me with these two questions ( show work plz )( it's ok if you only now one)
Answer:
1.8.09
2.-6
Step-by-step explanation:
1. 11b=89
b=89/11
8.09
2. 13+k/3=11
k/3=11-13
k/3=-2
k=-2*3
=-6
Answer:
Number 2 is - 6
Step-by-step explanation:
2. 13 + k/3 = 11
We can start off my subtracting 13 in both sides.
-13 + 13 + k/3 = 11 - 13
k/3 = -2. now we have to multiply 3 in both sides
3 x k/3 = -2 x 3
k = -6
Hope this helps!!

Answer:
[tex]\huge\boxed{\text{(A)}\ 0.36}[/tex]
Step-by-step explanation:
This sequence will have a pattern. Our goal is to try and find this pattern.
Our first two numbers are -45 and 9. The first relationship between these numbers that pops into my mind is 5. [tex]9 \cdot 5 = 45[/tex]. However, we go from -45 to 9. This means we have to divide by -5. [tex]-45 \div -5 = 9[/tex]
Let's check this actually is what the sequence is. It would be true if [tex]9 \div -5 = -1.8[/tex].
[tex]9 \div -5 = -1.8[/tex]
So -5 is the divisor.
To find the next term in the sequence, we divide -1.8 by -5.
[tex]-1.8 \div -5 = 0.36[/tex]
Hope this helped!
Is x – 3 a factor of 5x5 – 3x4 + 2x2 – 9x + 12 ?
Answer:
No
Step-by-step explanation:
Answer:
see explanation
Step-by-step explanation:
If (x - 3) is a factor of the polynomial then f(3) = 0
Given
f(x) = 5[tex]x^{5}[/tex] - 3[tex]x^{4}[/tex] + 2x² - 9x + 12 , then
f(3) = 5[tex](3)^{5}[/tex] - 3[tex](3)^{4}[/tex] + 2(3)² - 9(3) + 12
= 5(243) - 3(81) + 2(9) - 27 + 12
= 1215 - 243 + 18 - 27 + 12 = 975
Since f(3) ≠ 0 then (x - 3) is not a factor of the polynomial

-(-21) = -21 true or false
Answer:
False
Step-by-step explanation:
-(-21) is positive 21 since there are 2 negative signs, and -21 is negative, therefore they are not the same.
Hope this helps!
Answer:
False. It is equal to 21.
Step-by-step explanation:
-(21) would equal -21
However,
- (- 21) equals 21
The two negatives "cancel" each other out.
Answer: False. It is equal to 21.
There are 16 coins totaling $1.08. All 16 coins were pennies, nickels, and dimes. The number of dimes is equal to the sum of the number of pennies and the number of nickels. How many of each coin is there?
Answer:
Let the number of nickels be x
Let the number of pennies be y
Let the number of dimes be z
Now z=x+y
FIrst equation:
z+x+y=16
Subsittue for z:
x+y+x+y=16
y=8-x (subsitution)

A large ice chest holds 62 liters of water. A smaller chest holds 4/5 as much water
How many liters of water does the smaller chest hoid? Move a number to each box to show the answer. HELP ASAP.
Answer:
Step-by-step explanation:
Since a large ice chest holds the water = 62 liters
And smaller chest holds the water = [tex]\frac{4}{5}[/tex] of the larger ice chest
= [tex]\frac{4}{5}\times 62[/tex]
= [tex]\frac{248}{5}[/tex] liters
Therefore, fraction that represents the amount of ice water in the smaller ice chest will have 0 in the first box, 248 in the numerator and 5 in the denominator.
[tex]0\frac{248}{5}[/tex]
