Blair's average on the first five in-class tests is 67. If this is not pulled up to at least a 70,
Blair will not be allowed to watch any more of their favorite Netflix shows. To avoid
losing those access privileges, what is the lowest score Blair can afford to earn on the last
in-class test? Assume that all tests carry equal weight.
Answer:
85
Step-by-step explanation:
x/5 = 67
x=335
(x+y)/6 = 70
(335+y)/6 = 70
335+y=420
y=85
Answer:
85
Step-by-step explanation:
Average is calculated as
average = [tex]\frac{sum}{count}[/tex]
Here
[tex]\frac{sum}{5}[/tex] = 67 ( multiply both sides by 5 )
sum = 335
let x be the mark required to raise average to 70 , then
[tex]\frac{335+x}{6}[/tex] = 70 ( multiply both sides by 6 )
335 + x = 420 ( subtract 335 from both sides )
x = 85
Blair must score at least 85 on his last test
on weekends a movie ticket costs $10.50. form an inequality and solve it to find the maximum number of tickets kate can buy with $205
STEP BY STEP EXPLANATION PLEASE
$10.50
10 Tickets would be $105.00
$105.00 - $10.50 = $94.50 so 9 Tickets would be $94.50
$105.00 + $94.50 = $199.50
$205.00 - $199.50 = $5.50 which isn't enough for another ticket.
10 Tickets + 9 Tickets = 19 Tickets.
Isosceles trapezoid ABCD has legs AB and CD, and base BC. If AB = 3y - 4, BC = 2y -3, and CD = 4y - 18, find the value of y.
Answer:
(6)
Step-by-step explanation:
Since it is an isosceles trapezoid the length of the two legs (i.e. AB = 5y-10 and CD = 2y+8) are equal. In other words,
5y - 10 = 2 y + 8
Subtract 2y from each side:
5y - 2y - 10 = 8
Now add 10 to each side
5y - 2y - 10 + 10 = 8 + 10 =>
3y + 0 = 18 =>
3y = 18 =>
y = 6

write answer in scientific notation. (2.66×10¹³)÷(9.5×10⁵)
Answer: 28,000,000
Step-by-step explanation:
This is a long one.
Start with (1) 2.66 times 10 to the 13th = 26,600,000,000,000 {2.66E13}
(2) 9.5 times 10 to the 5th = 950,000
(3) 2.66E13 divided by 950,000 = 28,000,000

the ratio 18:24 in its simplest form is?
Answer:
3:4
Step-by-step explanation:
18 = 2 * 3 * 3
24 = 2 * 2 * 2 * 3
HCF = 2 * 3 = 6
Divide by 6
18: 24 = 18÷6 : 24÷6
= 3 : 4
Answer:
it's 3:4
Step-by-step explanation:
18 ÷ 6 : 24 ÷ 6
3 : 24 ÷ 6
=3:4

In general, units conversion is done by multiplying by a factor whose numerator and denominator have equal values, but different units. The units in that fraction need to be arranged to cancel the units you don't want and leave the units you do want.

Answer:
m∠6 = 115; m∠5 = 115; m∠1 = 130; m∠4 = 65
Step-by-step explanation:
44. m∠6 = 180 - 65 = 115
45. m∠5 = 180 - 65 =115
46. m∠1 = 180 - 50 = 130
47. m∠4 = 180 - (50+65) = 180 - 115 = 65

given f(x)=2x^3+kx-9 and x-1is a factor of f(x), then what is the value of k?
When it says the "x - 1 " is the factor of that function means when you find the root of the phrase x - 1 which is x = 1 , put it in the function then you have to get zero for the answer :
thus :
[tex]f(1) = 0[/tex]
Thus :
[tex]2 \times {1}^{3} + k(1) - 9 = 0[/tex]
So :
[tex]2 + k - 9 = 0[/tex]
[tex]k - 7 = 0[/tex]
Add both sides 7
[tex]k - 7 + 7 = 0 + 7[/tex]
[tex]k = 7[/tex]
There you go...
Have a great day ❤
