There are 10 girls and 5 boys in Ms. Sander's class. Each day, she randomly asks one student to take attendance. In 180 school days, which is the best prediction for the number of times that the student will be a girl?
Answer:
120
Step-by-step explanation:
The probability of a girl being picked one day = 10/15 = 2/3
Total number of days = 180
Therefore, the nunber of times it will be a girl = 2/3 x 180 = 2 x 60 = 120

Which of the following is the equation of a line that has a slope of -2 and passes through the
point (1,6)?
A.y=x+6
B.y=-2x+8
C.y=-2x+4
D.y=1/2x+4
Answer:
B. y = -2x + 8
Step-by-step explanation:
So the slope is the number that comes before the x, and if the slope is -2, that means the number before is -2, and it is.
And to know if it goes through (1, 6), put those numbers into the equation and see if they match up (x is the y-intercept)
6 = -2(1) + x
6 = -2 + x
x = 8
The one with both of these is B, which means B is the answer
Solve for y. 4- 2y + 8 = -6 y = [?]
Answer:
y=9
Step-by-step explanation:
4-2y+8=-6
-2y=-4-8-6
-2y=-18 divide by -2 both side
y=-18/-2
y=9
A small school bus holds 26 students. A larger school bus holds 150% as many students as the small school bus. How many students does the larger school bus hold?
Please help :/
Answer:
39
Step-by-step explanation:
To solve this problem we can use a proportion:
150 : 100 = x : 26
x = (26*150)/100 = 39
Answer:
39
Step-by-step explanation:
150% of 26 is 39
on a calculator do 26 times 150% and it equally 39
another way to do it is do 26 divided by 2 which equals 13, then add 13 to 26 and you get 39

What is the slope of a line that passes through the points (12,7) and (-14,19)?
F) -13/6
G) -1
H) -6/13
J) 3
Answer:
H) -6/13
Step-by-step explanation:
To find the slope of the line between a pair of two points, use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]. Substitute the x and y values of (12,7) and (-14,19) into the formula and simplify like so:
[tex]m = \frac{(19)-(7)}{(-14)-(12)} \\m =\frac{19-7}{-14-12} \\m = \frac{12}{-26} \\m = -\frac{6}{13}[/tex]
So, Option H is correct.

find the circumference and the area of the circle with a diameter of 15ft
Answer:
Circumference is pi times diameter so that would equal 15 pi. The formula to find the area of a circle is A=pi * r^2 So you divide 15 by 2 to find the radius. r=7.5 Then you square it and multiply it by pi and get 56.25pi which is about equal to 176.715
The 5th graders want to raise money for their overnight camping trip by selling cornbread during the school Chili Cook-Off contest. All the pans of cornbread are square. A pan of cornbread costs $12. The customers can buy any fractional part of a pan of cornbread and pay that fraction of $12. For example, ½ of a full pan costs ½ of $12.
Answer:
1 / 12 ; $1
Step-by-step explanation:
Pan was 1/4 full and she buys 1/3 of the cornbread in the pan
The fraction of cornbread she buys is :
1/3 of 1/4
1/3 * 1/4 = 1/12
Hence, she bought 1/12 of cornbread
The amount she pays :
Cost of 1 pan = $12
Therefore, the cost of 1/12 of a pan will be :
1/12 * $12 = $1
Hence, she'll pay $1

6. Coach Medina bought uniforms for the 10 players on his soccer team.
Each shirt cost $12.50. Each pair of shorts cost $13.50. What was the total
cost for the 10 team uniforms?
Answer: $260
Step-by-step explanation:
Uniform = shirt + shorts
($12.50 x 10) + ($13.50 x 10) = $260
or
($12.50 + $13.50) x 10 = $260
A 26-ft ladder leans against a building so that the angle between the ground and the ladder is 81 degrees. How high does the ladder reach on the building? the answer is in ft
Answer:
25.7 feets
Step-by-step explanation:
From the diagram attached, we could use trigonometry to obtain the height,h :
Using the trigonometric relation :
Sin θ = opposite / hypotenus
Opposite = h
Hypotenus = 26 feets
Sin 81° = h / 26
Height, h = 26 * sin 81°
h = 26 * 0.9876883
h = 25.679
Height, h = 25.7 feets

Answer:
66m
Step-by-step explanation:
9+3+16+3+5+12+10+s
the s would 8 because
12+5 is 17
17-9 would be 8 so we would add 8.
9+3+16+3+5+12+10+8
Answer:
66 m
Step-by-step explanation:
We know that Perimeter is sum of all the sides of any triangle / quadrilateral / polygon . Here we see that that the side lenght are ,
8cm , 10cm , 12cm , 3m , 5m , 16m ,9m , 3cm .
On adding these , we will get Perimeter .
⇒ P = 8cm + 10cm + 12cm + 3m + 5m + 16m + 9m + 3m
⇒ P = 66m
Hence the required answer is 66mHELP I NEED HELP ASAP

Question 9:
Find the sine of angle I
796
195
Answer:
sin I = 0.244
Step-by-step explanation:
Given that,
Perpendicular, P = 195
Hypotenuse, H = 796
We need to find the value of [tex]\sin(I)[/tex]. We know that,
[tex]\sin\theta=\dfrac{P}{H}[/tex]
Substitute all the values,
[tex]\sin I=\dfrac{195}{796}\\\\\sin(I)=0.244[/tex]
So, the value of sin(I) is equal to 0.244.
Find the area of this parallelogram. Be sure to include the correct unit in your answer. 8 in, 15 in, and 6 in
Answer:
90 in²
Step-by-step explanation:
The diagram isn't attached :
However, taking the base of the parallelogram, b as 15 in
The height as 6 in
And the Slant height as 8 in
The Area of a parallelogram is given as :
Area, A = Base, b multiplied by height, h
A = b * h
Hence, Area of the above parallelogram is:
A = 15 in * 6 in
A = 90 in²
1/3(6z+7.2)=0.5(8z+2)-0.4
A z=0.8
B z=0.9
C z=2.8
D z=3.6
please help
Answer:
B z = 0.9
Step-by-step explanation:
1/3(6z + 7.2) = 0.5(8z + 2) - 0.4
Multiply both sides by 6.
12z + 14.4 = 24z + 6 - 2.4
-12z = -10.8
z = 0.9
