Answer: 114
Step-by-step explanation: Because 48+18 = 66 and 180-66 is 114.
Answer:
C
Step-by-step explanation:
∠ BHC = ∠ FAB = 48° ( alternate angles )
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ ABC is an exterior angle of the triangle, thus
∠ ABC = ∠ BHC + ∠ ECB = 48° + 18° = 66° → C

Which graph represents -3x + 5y = -15
Answer:
B
Step-by-step explanation:
The y intercept is -3 because -15/5=-3
The obtained coordinates are matching with graph B. Therefore, option B is the correct answer.
The given equation is -3x + 5y = -15.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Rearrange the given equation that is 5y = -15+3x
y= 3/5 x - 3
Put x=0, y=0-3
y=-3
Put x=5, y=3-3
y=0
Now, the coordinates to plot graph are (0, -3) and (5, 0).
The obtained coordinates are matching with graph B. Therefore, option B is the correct answer.

A falcon flying 55 mph crosses a lake in 1 minute. How long would it take a hummingbird flying 45 mph to cross the same lake?
Answer:
1 2/9 minutes
Step-by-step explanation:
55 mph
55 / 60 = 11/12
11/12 of a mile = 1 minute
45 mph
45 / 60 = 3/4
3/4 of a mile = 1 minute
11/12 divided by 3/4
11/12 * 4/3
We can cross-cancel
11/3 * 1/3 = 11/9 = 1 2/9
It takes 1 2/9 minutes for the hummingbird to cross the lake
Hope this helps!
(Please let me know if I did something wrong!)
The hummingbird will take 1 minute 13 seconds.
Let the time that will be taken by the hummingbird be represented by x
Note that 1 minute = 60 seconds
Based on the information given, the equation that'll be used in the question will be:
45/55 = 60/x
Cross multiply
(45 × x) = (60 × 55)
45x = 3300
x = 3300/45
x = 73.33 seconds
x = 1 minute 13 seconds
The hummingbird will take 1 minute 13 seconds.

-8x-3=13-9x what is the answer for x?
Answer:
x=16
Step-by-step explanation:
-8x-3=13-9x
-8x+9x=13+3
x=16
Answer:
x = 16
Step-by-step explanation:
subtract 8x from both sides
-3 = 13 -x subtract 13 to both sides
-16 = -x multiply both sides by -1 which gives you 16 = x
1) 4x + 3 23

Chelsea and her friends are making small fruit baskets for their neighbors. They have 90 pears, 45 peaches, and 75 apples. What is the greatest number of baskets they can make if each basket has the same number of pears, the same number of peaches, and same number of apples, with no fruit leftover?
Answer:
15 baskets
Step-by-step explanation:
This question is a GCF question
The first step would be to find the factors of 45, 75 and 90
The factors of 45 are: 1, 3, 5, 9, 15, 45
The factors of 75 are: 1, 3, 5, 15, 25, 75
The factors of 90 are: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90
The greatest common factor is 15.
Therefore, the greatest number of baskets they can make if each basket has the same number of pears, the same number of peaches, and same number of apples, with no fruit leftover is 15 baskets

A pilot of a helicopter plans to release a bucket of water on a forest fire. The height y in feet of water t seconds after its release is modeled by y = − 16 t 2 − 2 t + 400 . How long will it take for the water to reach the ground? Round to one number after the decimal point.
Answer:
4.93 seconds
Step-by-step explanation:
The height y in feet of water t seconds after its release is given by the equation as follows :
[tex]y=-16t^2-2t+400[/tex]
We need to find the taken taken for the water to reach the ground. When it reach the ground, y will be equal to 0. So,
[tex]-16t^2-2t+400=0[/tex]
Above is a quadratic equation whose solutions can be calculated as follows :
[tex]t=\dfrac{-(-2)\pm \sqrt{(-2)^2-4\times (-16)\times 400} }{2\times (-16)}\\\\t=\dfrac{-(-2)+ \sqrt{(-2)^2-4\times (-16)\times 400} }{2\times (-16)}, \dfrac{-(-2)- \sqrt{(-2)^2-4\times (-16)\times 400} }{2\times (-16)}\\\\t=-5.062\ s\ \text{and}\ 4.93\ s[/tex]
Neglecting negative value.
Hence, it will take 4.93 seconds for the water to reach the ground

Yes and No, if you divide 6 by 3, 2, or 1, it will have a quotient less than 6. Dividing 6 by 3 = 2, 6 by 2 = 3, 6 by 1 = 6.
