You need to score a 90 or higher on your next test to make the honor roll. If x represents the score on your next test, which inequality represents the situation?
x > 90
x< 90
x ≥ 90
x ≤ 90
Answer:
x ≥ 90
Step-by-step explanation:
it says 90 or higher which also means "at least 90", which means greater than or equal to 90.
write f(x)=-(x+3)^2+8 in standard form
Answer:
f(x) = -x^2 -6x - 1
Step-by-step explanation:
Answer:
y=-x^2-6x-1
Step-by-step explanation:
f(x)=-(x+3)^2+8
f(x)=-(x+3)(x+3)+8
f(x)=-(x^2+3x+3x+9)+8
f(x)=-x^2-3x-3x-9+8
f(x)=-x^2-6x-9+8
f(x)=-x^2-6x-1
y=-x^2-6x-1

Sebastian is making bags of trail mix for hiking club. He will use 21 ounces of walnuts, 10.2 ounces of almonds, and 15.6 ounces of cashews. This amount makes 24 bags of trail mix. How many ounces are in each bag?
Answer:
1.95 ounces
Step-by-step explanation:
ounces in each bag = total ounces in 24 bags / number of bags
total ounces in 24 bags = 21 ounces of walnuts + 10.2 ounces of almonds + 15.6 ounces of cashews = 46.8 ounces
46.8 / 24 = 1.95 ounces
The width of a rectangle is 4cm less than the length. If each dimension were increased by 3cm, the width of the new rectangle formed would be 2/3 the length of the new rectangle. Find the dimensions of the original rectangle.
Answer:
The original length is 9 cm and the original width 5 cm
Step-by-step explanation:
The area of a rectangle A is given as the product of its' length L and width W.
Given that the width of a rectangle is 4cm less than the length then
W = L - 4
If each dimension were increased by 3cm, then the new
Length
= L + 3
Width
= W + 3
the width of the new rectangle formed would be 2/3 the length of the new rectangle
W + 3 = 2/3(L + 3)
3W + 9 = 2L + 6
3W = 2L +6 - 9
3W = 2L - 3
Recall that W = L - 4
3(L - 4) = 2L - 3
3L - 12 = 2L - 3
3L - 2L = 12 - 3
L = 9 cm
W = 9 - 4
= 5 cm

step-by-step explanation:
look up what alternate interior angles look likethis relationship would be called alternate interior anglesAnswer:
If they are parallel then they are equal alternayive angle
Step-by-step explanation:
(3x+16)°=(5x-54)°16+54=5x-3x70=2x70/2=xx=35Find the value of x. Then find the measure of each interior angle. Show work algebraically
Answer:
Step-by-step explanation:
W=180-144
W=36 degrees
The sum of angles in a triangle always sum to 180 degrees.
6x+1+7x+36=180
13x+37=180
13x=143
x=11
U=6x+1
U=6(11)+1=67 degrees
V=7x
V=7(11)=77 degrees so
x=11 degrees, U=67 degrees, V=77 degrees, and W=36 degrees.

Layla bought a new computer for $500. Each year, the value of the computer decreased by 50% of the previous years value. At this rate, what can Layla expect the approximate value f the computer to be after 4 years?
Layla bought a new computer for $500. Each year, the value of the computer decreased by 50% of the previous years value. At this rate, what can Layla expect the approximate value f the computer to be after 4 years?
A. $125.00
B. $62.50
C. $31.25
D. $250.00
A. $125.00
B. $62.50
C. $31.25
D. $250.00
Answer:
Answer = C.31.25
Step-by-step explanation:
SO there are 4 years and every year the price gets 50% of so we take it as 100/2 = 50% so we have to divide 500 by 2 four times that is -
1. 500/2 ( 50% of 500) = 250
2. 250/2 (50% of 250) = 125
3. 125/2 (50% of 125) = 62.50
4. 62.50/2 (50% of 62.50) = 32.25
so we divided 500 4 times to get the answer as 32.25$

Answer:
.80
Step-by-step explanation:
Hey There,
Cosine = adjacent / hypotenuse
the adjacent of c is 16
the hypotenuse is 20
so cos C = 16/20 or .80
Answer:
Step-by-step explanation:
cos=(adjacent side)/(hypotenuse)
cosC=16/20
cosC=4/5
cosC=0.80 (to nearest hundredth)

Hadley runs several times around the
track. One lap around the track is
equal to 0.15 miles. She then runs 0.4
miles home for a grand total of 1.75
miles. Write an equation to help you
determine the number of laps Hadley
ran around the track.
#21
08
The answer is 9.
1.75 - 0.4 = 1.35
1.35 ÷ 0.15 = 9
Ron and Freddy built structures out of snap cubes. Ron's tower had an 8-inch square base. Freddy had a 6-inch square base. If Ron's tower had a volume of 320 cubic inches and Freddy's had a volume of 180 cubic inches, Whose tower was taller? Explain your reasoning.
Answer: Ron tower's
Step-by-step explanation:
Given
Ron tower has a base of [tex]A_r=8\ in.^2[/tex]
Freddy tower has a base of [tex]A_f=6\ in.^2[/tex]
Suppose the tower is in the shape of a square prism
The volume of Ron and Freddy tower is [tex]320\ \text{and}\ 180\ in.^3[/tex]
The volume of a square-based prism is [tex]V=\frac{1}{3}a^2h[/tex]
[tex]\therefore \text{height of Ron tower is}\ h_r=\dfrac{3V}{A_r}\\\\\Rightarrow h_r=\dfrac{3\times 320}{8}=120\ in.[/tex]
The height of Freddy tower is
[tex]\Rightarrow h_f=\dfrac{3V}{A_f}\\\\\Rightarrow h_f=\dfrac{3\times 180}{6}=90\ in.[/tex]
Thus, the height of Ron's tower is more than Freddy's tower by [tex]30\ in.[/tex]
How many solutions does the system have?
y=3x+3
y=−2x+3
choose 1 answer
A) Exactly one solution
B) No solutions
C) Infinitely many solutions
Answer:
A
Step-by-step explanation:
Given the 2 equations
y = 3x + 3 → (1)
y = - 2x + 3 → (2)
Substitute y = 3x + 3 into (2)
3x + 3 = - 2x + 3 ( add 2x to both sides )
5x + 3 = 3 ( subtract 3 from both sides )
5x = 0 , then
x = 0
Substitute x = 0 into (1)
y = 3(0) + 3 = 0 + 3 = 3
solution is (0, 3 ) → A

Answer:
159 degrees
Step-by-step explanation:
A full semicircle (or half circle) has a degrees of 180. And x is equal that semicircle so x = 180, now if we subtract 21 from 180 we get 159, so X = 159.
(financial math) Elementary and Secondary Education is paid mostly from:
O Corporate Taxes
О Defense Taxes
O State Taxes
O Federal Taxes
State taxes.
According to Urban dot org, school funding is a blend of federal, state, and local dollars.
State taxes are more likely to be correct due to education being the state's responsibility.
If this is incorrect, please, don't refrain to tell me. Thank you.
