Josh hit a baseball straight up into the air. The equation below describes the
height of the ball (h), in meters, as a function of time (t) in seconds.
h(t) = -9.8t2 + 30t + 1.5
What is the height of the ball after 3 seconds?
Answer:
3.3 meters
Step-by-step explanation:
h(3)=-9.8(3)^2+30(3)+1.5
=-88.2+90+1.5
=3.3
Choose 3 values that would make this inequality true. 12 57 +n
Answer:
8, 10, 5
Step-by-step explanation:
7+8=15, 7+10=17, 7+5=12. You’re basically substituting the numbers in for n and seeing if its greater than or equal to 12.
Is this a function even though there’s a -1 and a 1 in the same x column?
answer:
yes, because they have a common difference and it makes sense. in order to determine if this is a function, you would have to find their difference for each column. the x column has a difference of 2 for all. similarily, the y column has a difference of 2 for all. therefore, it is a function.

1. The perimeter of a piece of paper is 18 cm.
a. List three different possible sets of dimensions for the paper, as well as the resulting areas.
Answer:
a) length = 3 and width = 6
Area of the rectangle = 3 × 6 = 18 cm²
b) length = 7 and width = 2
Area of the rectangle = 7 × 2 = 14 cm²
c) length = 5 and width = 4
Area of the rectangle = 5× 4 = 20 cm²
Step-by-step explanation:
Step(i):-
Given perimeter of the paper = 18 cm
we know that the paper has a rectangle shape
The perimeter of the rectangle = 18 cm
2( l + w ) = 18
a)
we choose length = 3 and width = 6
The perimeter of the rectangle = 2( 3+6) = 18 cm
Area of the rectangle = 3 × 6 = 18 cm²
b)
we choose length = 7 and width = 2
The perimeter of the rectangle = 2( 7+2) = 18 cm
Area of the rectangle = 7 × 2 = 14 cm²
c)
we choose length = 5 and width = 4
The perimeter of the rectangle = 2( 5+4) = 18 cm
Area of the rectangle = 5× 4 = 20 cm²

Answer:
C 15
Step-by-step explanation:
20÷4x3=15
Answer:
C. 15
Step-by-step explanation:
If B's side length is 20, that means in the ratio 3:4 the 4 represents B's side length.
Multiply both sides of the ratio by 5:
15: 20
The answer is 15.
i need help on the math question if it's right I'll give brain.
Answer: \frac{2}{5} ; or, write in decimal form: 0.4 .
Step-by-step explanation:
Rewrite as:
_______________________
[tex]\frac{4x}{7} = \frac{8}{35}[/tex] ;
________________________
Now, "Cross-factor multiply":
that is:
_____________________
→ Given: [tex]\frac{a}{b} =\frac{c}{d}[/tex] ;
→ ad = bc ; (b≠0 ; d≠0) ;
_____________________
As such:
4x * 35 = 7 * 8 ;
_______________________
We can divide one side of the equatiuon by "4" ; and one side by "7" :
[tex]\frac{4x*35}{4*7} = \frac{7*8}{4*7}[/tex] ;
_______________________
We can simplify the "left-hand side":
"4/4 = 1 " ; and "35/7 = 5 " ; & we are left with "x * 5" ; or "5x " .
________________________
We can simplify the "right-hand side":
"7/7 = 1 " ; and: "8/4 =2 " ; to get: "2/1" ; which equals "2".
_________________________
So; we have: " 5x = 2 " ; Solve for "x" ;
__________________________
Divide each side of the equation by "5" ; to isolate "x" on one ide of the equation; & to solve for: "x" ;
__________________________
" 5x/5 = 2/5 " ; We cancel out the "5x/5" to "1x"; which equals "x":
→ x = [tex]\frac{2}{5}[/tex] ; or, write in decimal format: "x = 0.4" ;
___________________________
\frac{2}{5}

Answer:
[tex]x = 0.4[/tex]
Step-by-step explanation:
[tex]\frac{7}{4} x \frac{4}{7} = \frac{7}{4} x \frac{8}{35}[/tex]
Reduce the number with the greatest common factor 7
[tex]\frac{1}{4} x 4x= \frac{7}{4}x\frac{8}{35}[/tex]
[tex]x=\frac{7}{4}x\frac{8}{35}[/tex]
[tex]x=7x\frac{2}{35}[/tex]
[tex]x=\frac{2}{5}[/tex]

72 is 25% of students that have a cat, how many total students are there?
Answer:
288
Step-by-step explanation:
1. Use the formula: P*T=N
P = percent, T = Total, and N is the other number.
2. So, P*T=N, therefore, 25%*T=72
3. Simplify .25*T=72
4. So get the Total (T) by itself, you have to divide both sides by .25
5. T = 72/.25

3x + 2y = -9
X – Y = -13
Answer:
x =-7. .y=6
Step-by-step explanation:
3x + 2y = -9
(X – Y = -13)×3
3x + 2y = -9
3x – 3y = -39
5y = 30
y=6
3x +2(6)=-9
3x=-21
x=-7
