The total height of 4 building blocks and a flagpole on top is 23 cm.
The total height of 9 building blocks and a flagpole on top is 43 cm.
Find the height of a building block and the height of a flagpole.
Height of a building block =
cm
Height of a flagpole =
cm
Answer:
building block = 4cm
flag pole = 7 cm
Step-by-step explanation:
9b + f = 43
4b + f = 23
5b = 20
b = 4
16 + f = 23
23 - 16 = 7
f= 7
36 + 7 = 43
A culture started with 5,000 bacteria. After 4
hours, it grew to 5,500 bacteria. Predict how
many bacteria will be present after 13 hours.
Round your answer to the nearest whole
number.

Answer: After 13 (12) hours, there would be 6,500 bacteria across the culture.
Step-by-step explanation:
The bacteria grew by 500 each 4 hours, so to know how much there would be 13 hours later:
Simple, add 500 bacteria to every 4 hours until you reach 13 hours. 4 = 5.5k, 8 = 6k, 12 = 6.5k. Now, 12 is closer to 13 than anything we would've gotten if we kept going.

Mick and Jackie buy a large sandwich to share. They each eat 2/5 of the sandwich.
How much of the sandwich is remaining?
Show your work.
Answer:
1/5 is remaining
Step-by-step explanation:
if there is two people each eating 2/5 we would just multiply 2/5 by 2 and get 4/5 then we would subtract 4/5 from 1 and get 1/5
Answer:
1/5
Step-by-step explanation:
Sandwich eaten by Mick and Jackie = [tex]\frac{2}{5}+\frac{2}{5}\\\\[/tex]
= [tex]\frac{2+2}{5}=\frac{4}{5}[/tex]
Remaining sandwich = 1/5

2.) 15x18+12/3+9
Answer:
283
Step-by-step explanation:
15(18) + 12/3 + 9
270 + 4 + 9 = 283
Answer:
283
Step-by-step explanation:
First, we have the equation 15 × 18 + 12/3 + 9.
If we refer to PEMDAS, division comes first, then multiplication, addition, and subtraction.
So, the equation becomes 15 × 18 + 4 + 9.
Now, we can multiply 15 × 18 in the equation.
The equation becomes 270 + 4 + 9.
4 + 9 = 13.
270 + 13 = 283.

A gym membership is offered in January for 14.99 per month. If you pay upfront for the year, you are given a 15% discount on the monthly fee. How much money will you save after a year by paying upfront rather than monthly
Answer:
$27 approx
Step-by-step explanation:
Given data
Membership fee= 14.99 per month
for a year the fee is 14.99*12= 179.88
discount = 15%
=15/100*179.88
=0.15*179.88
=26.982
Hence for a year, you will save $27 approx
Jason predicted that 277 students would attend the school dance. The actual number was 250. What is the precent error of Jason's prediction?
Answer:
9.7%
Step-by-step explanation:
Given data
Expected value= 277
Actual value= 250
%Error= Actual- Expected/Expected *100
%Error= 250-277/277 *100
%Error= 27/277 *100
%Error= 0.097*100
%Error= 9.7
Hence the error is 9.7%

A TV has a length of 68 inches and a height of 51
inches. When TV's are advertised the size listed is the
diagonal length. What would be the advertised size of
this TV?
Answer:
85 inches
Step-by-step explanation:
Using pythag. A^2 + B^2 = C^2
(68*68) + (51*51) = 7225^2
Thus if you square root 7225, you get your answer - 85 inches.

Find the zeros
Answer:
The zeroes of this polynomial are [tex]x_{1} \approx 0.847[/tex] and [tex]x_{2} \approx -1.180[/tex].
Step-by-step explanation:
Let [tex]3\cdot x^{2}+x - 3 = 0[/tex], the quickest and most efficient approach to find the zeroes of this second order polynomial is by Quadratic Formula. For all [tex]a\cdot x^{2}+b\cdot x + c = 0[/tex], roots are determined by:
[tex]x_{1,2} = \frac{-b\pm \sqrt{b^{2}-4\cdot a\cdot c}}{2\cdot a}[/tex] (1)
Where [tex]a[/tex], [tex]b[/tex], [tex]c[/tex] are coefficients of the polynomial.
If we know that [tex]a = 3[/tex], [tex]b = 1[/tex] and [tex]c = -3[/tex], then roots of the polynomial are, respectively:
[tex]x_{1,2} = \frac{-1\pm\sqrt{1^{2}-4\cdot (3)\cdot (-3)}}{2\cdot (3)}[/tex]
[tex]x_{1,2} =\frac{-1\pm \sqrt{37}}{6}[/tex]
The zeroes of this polynomial are [tex]x_{1} \approx 0.847[/tex] and [tex]x_{2} \approx -1.180[/tex].
