There are 4 red balls in a bag and an unknown number of white balls. If we randomly
choose a ball from the bag, the probability of getting a white ball is larger than the
probability of getting a red ball. What might be the number of white balls in the bag?
Step-by-step explanation:
well if there were 5 white the probability is 5/9 vs 4/9 for red. so the number of white balls is anything greater than or equal to 5
A store sells a box of breakfast cereal for $3. Write an equation to relate the number of boxes b to total sales T.
Answer:
b = T / $3
T = $3b
Step-by-step explanation:
Given that:
Cost per box of cereal = $3
Total amount from sale of cereal = T
Number of boxes sold = b
Number of boxes sold = (Total amount from sale of cereal / cost per box)
Number of boxes (b) = T / $3
T = $3b
If a model of a dinosaur is 3.75 feet and the scale factor for the actual dinosaur is 1:24. What is the size, in feet, of the actual dinosaur?
Answer: 120
Step-by-step explanation:
Next, write ratios to represent the unknown actual length and width of the display to the scale length and width of the display.
LengthWidth=scaleactual=4l=scaleactual=8w
Then, write two proportions by setting the two length ratios equal to one another and the two width ratios equal to one another. The given unit is feet.
LengthWidth=4l=1160=8w=1160
Next, cross multiply each equation.
LLWW=4×160=640 feet=8×160=120 feet
Then, to find the area of the display, multiply length times width.
The actual size of the dinosaur is 90 feet.
What is a scale factor?The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).
Given:
A model of a dinosaur is 3.75 feet,
and the scale-factor for the actual dinosaur is 1:24.
So,
the size of the actual dinosaur = model size x the scale-factor
The size of the actual dinosaur = 24 x 3.75
The size of the actual dinosaur = 90 feet.
Therefore, the actual size is 90 feet.

10/27=a/135
what is the answer for this equation?
Answer:
So we have this equation:
10/27 = a/135
What we can do is multiply both sides by 27 and 135:
10*135 = a * 27
1350 = 27a
a = 1350/27. = 50.

HELP AND WILL GIVE BRAINLIEST!!! Solve for x
Answer:
let the opposite angle of 43=y
57°+43°+y=180°[by sum of all angle is 180°]
100+y=180°
y=180°-100
y=80°
opposite angle of x is equal to the 80°
so the equation will be like this
x+x+80°=180°
2x+80°=180°
2x=180°-80°
2x=100
x=100/2
x=50°
so the value of x is 50°

What is the value of y when the value of x is 1?
Solve for x. (Enter your answers as a comma-separated list.)
Answer:
x=1
Step-by-step explanation:
The value of x is 1 for the given determinant.
The determinant is defined as a scalar value that is associated with the square matrix. If X is a matrix, then the determinant of a matrix is represented by |X| or det (X).
Given a determinant value equal to zero,
To calculate the value of x,
Firstly, calculate the determinant as follows and equate it to zero:
[tex]1(3 \times-2-(-4\times3))-x(1 \times-2-3 \times0)+2(1\times-4-0\times3)=0\\\\[/tex]
[tex]1(-6+12)-x(-2)+2(-4)=0\\\\[/tex]
[tex]6+2x-8=0\\[/tex]
Solve like terms together and try to separate variable on LHS, so that it becomes easy to calculate the value of it.
Thus, the value of x is 1.

a. Equation representing the number os students.
b. The number of Boys and Girls.
Answer:
a. 3g + g = 53
b. 40 boys and 13 girls
Step-by-step Explanation:
(3g = number of boys)
(g = number of girls)
3g + g =53
4g = 53
g = 13.2
53 - 13.2 = 39.8 (boys)
we round to the nearest tenth on both
girls 13.2---13
boys 39.8---40
In triangle KLM, the measure of angle M is 90 degrees, the measure of angle K is 75 degrees, and LM is equal to 6.3 feet. Find the length of KL to the nearest tenth of a foot.
Answer:
6.5feet
Step-by-step explanation:
Using the SOH CAH TOA identity
<K = 75 degrees
opposite = LM = 6.3 feet
Hypotenuse = KL
sin theta = opp/hyp
sin 75 = 6.3/x
x = 6.3/sin75
x = 6.3/0.9659
x = 6.5feet
Hence the length of KL to the nearest tenth of a foot is 6.5feet

Given:
[tex]-\dfrac{33}{16}[/tex] should be divided by a number to get [tex]-\dfrac{11}{4}[/tex].
To find:
The unknown number.
Solution:
Let [tex]-\dfrac{33}{16}[/tex] should be divided by x to get [tex]-\dfrac{11}{4}[/tex].
[tex]\dfrac{-\dfrac{33}{16}}{x}=-\dfrac{11}{4}[/tex]
[tex]-\dfrac{33}{16}=-\dfrac{11}{4}x[/tex]
Multiply both sides by 16.
[tex]-33=-44x[/tex]
Divide both sides by -44.
[tex]\dfrac{-33}{-44}=x[/tex]
[tex]\dfrac{3}{4}=x[/tex]
Therefore, the unknown number is [tex]\dfrac{3}{4}[/tex].
