If a car drove 180 miles in 3 hours and a truck drove 150 miles in 2 hours, what is the speed (in miles per hour) of the faster vehicle?
Step-by-step explanation:
Divide 180 by 3 = 60
Divide 150 by 2 = 75
The faster vehicle is truck and its speed is 75 mph
At birth, the rhino weighed 85 pounds. The rhino gained the same amount of pounds each month for 6 months. After 6 months, the rhino weighed 493 pounds. How much weight did it gain each month?
Answer:
68 pounds a month
Step-by-step explanation:
so what i did is subtract 85 because that was the starting weight, now we have 408 I divided 6 (how many months) and got 68.
Find the x-intercept and the y-intercept of the graph of the equation. 2x + 3y = 18
Answer:
x-intercept is at (9, 0)
y-intercept is at (0, 6).
Step-by-step explanation:
The x intercept occurs when y = 0:
2x + 3*0 = 18
2x = 18
x = 9,
y-intercept, when x = 0:
2(0) + 3y = 18
y = 6.

Anyone I need help with this problem plss
Answer:
About 1.23 standard deviation above the mean
Step-by-step explanation:
From what we have here, we need to calculate the difference between the given value and the mean and divide by the standard deviation
That would be through calculating the z score as follows;
z-score = (x - mean)/SD
where x is the given value
z-score = (87-71)/13 = 1.23
Since the score is bigger than the mean, the correct choice here is that the score is about 1.23 standard deviation above the mean

Answer:
3rd option
Step-by-step explanation:
The equation of a parabola in vertex form is
f(x) = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k ) = (- 1, - 25 ) , then
f(x) = (x - (- 1) )² - 25 , that is
= (x + 1)² - 25 ← expand using FOIL
= x² + 2x + 1 - 25
= x² + 2x - 24

17. What are the three angle measures in the triangle shown below?
Answer:
Option (1)
Step-by-step explanation:
By using triangle sum theorem in the given triangle,
(5x - 7)° + (11x - 4)° + (3x + 1)° = 180°
(5x + 11x + 3x) - (7 + 4 - 1) = 180
19x - 10 = 180
19x = 190
x = 10
Therefore, (3x + 1)° = 30 + 1
= 30°
(11x - 4)° = 110 - 4
= 106°
(5x - 7)° = 43°
Therefore, Option (1) will be the correct option.
In a game you are required to pull a letter from a bag that contains one of each vowel in the alphabet (A, E, I, O, and U) and then roll a standard die. What is the probability you will draw the letter E and roll an even number?
Answer:
1/10
Step-by-step explanation:
the no of different probabilities = 6*5 = 30
no of times E can come with an even no = 3
so 3/30=1/10

[tex]\frac{y2-y1}{x2-x1} =\frac{-9-0}{3-0} = -9/3 = -3x[/tex]
y=-3x
hope that answers your question
Step-by-step explanation:
Answer: C. y = -3x
Step-by-step explanation:
Since the line runs through the origin (0, 0), we don't have to write a y-intercept. To calculate the slope, we determine the change in y value over the change in x value.
Looking at the graph, we see that for every +1 x, we have -3 y, so the slope is -3, which we multiply by x in the equation.

Julio bought 7 science fiction novels (s) and 7 comic books c) from the bookstore. His purchases can be represented by the expression 7(s + c). Part B: The cost of a science fiction novel is $5.99 and the cost of a comic book is $6.49. Sales tax is 6%. What is the total amount that Julio spent at the bookstore? Round your answer to the nearest cent. Show your work?
Answer:
$92.60
Step-by-step explanation:
7($5.99) + 7($6.49)=$41.93
$41.93 + $45.43 = $87.36
$87.36 + ($87.36 × 6%=0.06)
$87.36 + (0.06 × $87.36=5.24)
$87.36 + $5.24= $92.60
A loading ramp is extended from the back of a truck to form a 30° angle with the ground. The truck and the ramp are both on level ground. If the length of the ramp is x feet, how high is the back of the truck from the ground?
A) 2x feet
B) x√3/2
C) x√3
D) x/2
Answer:
Height between ground and truck = 5.5 feet
Step-by-step explanation:
Given:
Angle of elevation = 30°
Length of the ramp = 11 feet
Find:
Height between ground and truck
Computation:
Length of the ramp = Hypotenuse
Height between ground and truck = Perpendicular
Sin θ = Perpendicular / Hypotenuse
Sin 30 = Height between ground and truck / Length of the ramp
0.5 = Height between ground and truck / 11
Height between ground and truck = 0.5 x 11
Height between ground and truck = 5.5 feet

1. similar triangles.
they have the same angles, and therefore the change factor for their side lengths (to change from one similar triangle to the other) must be the same for all sides.
tan of an angle is the length of the outside tangent touching the circle starting at x=1,y=0 and going up perpendicular all the way until it crosses the line from the center of the circle enclosing the angle.
so, we have one triangle of the corners ABC, where A=(0,0), B=(1,0), C=(1,tan of the angle = sqrt(3)).
and we have a similar triangle ADE, where A=(0,0), D=(cos of the angle=1/2,0), E=(1/2,m).
we know because of the described similarity that the sides BC and DE must have the same ratio as e.g. AB and AD.
AB=1, AD=1/2, so the ratio AD/AB = 1/2.
now, BC=sqrt(3). DE=m and must follow the same ratio as AD/AB. DE/BC=1/2.
=> m/sqrt(3)=1/2 => m=sqrt(3)/2
2. circle equation : x^2 + y^2=r^2
x=1/2, y=m, r=1
(1/2)^2 + m^2 = 1^2 (= 1)
1/4 + m^2 = 1
m^2 = 3/4
m = sqrt(3)/sqrt(4) = sqrt(3)/2

is 4 a factor of 93 explain in words
IM MAKING THE POINTS HIGH
No 4 is not a factor of 93 :)
let me know if this helped<3
Explanation: a factor is whether or not a number can be multiplied with another number, 4 cannot be multiplied by any number to evenly come out as 93, the way you can check this is by dividing 93 by 4, if it comes out as a whole number with no decimal or remainder than the number is a factor if it has a decimal or remainder it is not a factor
Answer:
No.
Step-by-step explanation:
The first method entails simply listing all factors of 93 and then seeing if 4 is one of them. The factors of 93 are 1, 3, 31, and 93. Looking at the list, you see that 4 is not on the list, and the answer to "is 4 a factor of 93?" is therefore no. For the second and perhaps easier method, we divide 93 by 4 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 4 is a factor of 93. If the quotient is a fractional number, then 4 is not a factor of 93. 93 divided by 4 is 23.25 which is a fractional number. Thus, once again, the answer to "Is 4 a factor of 93?" is no.

Rachel made 6 birdhouses and sold 4 of them for $19 each. Is it reasonable that she had $57 in receipts?
Answer: It is not reasonable. She should have $76
Step-by-step explanation:
If Rachel sold 4 birdhouses for $19 each, the amount that she should have received is:
= 19 * 4 birdhouses
= $76
It is therefore not reasonable that she had only $57 in receipts as she should have $76.
