Todd is 33 years old; his nephew Jacob is 12. In how many years will Jacob be ½ his uncle Todd's age?
Answer:
9 years
Step-by-step explanation:
Jacob will be half his uncle's age when his age is equal to the difference in their ages.
__
The difference is 33 -12 = 21 years. Jacob will be half Todd's age in 21 -12 = 9 years, when Jacob is 21 and Todd is 42.
On the last day of vacation, the Hernandez family drove 252 miles from a state park to their home. That drive covered 35% of the total distance the family traveled during their vacation. What is the total distance the Hernandez family traveled during their vacation
Answer:
720 miles
Step-by-step explanation:
We are given a distance and a fraction of the total that it represents. This lets us write the relation ...
252 = 0.35D . . . . . . where D is the total distance traveled
252/0.35 = D = 720 . . . . divide by the coefficient of D
The Hernandez family traveled 720 miles during their vacation.
In ΔPQR, ∠P and ∠Q are complementary angles.
.
Answer:
P + Q = 90
P = 90 - Q
Cos (p) = cos (90-Q) = sinQ = 4/5 (given)
You can find CosQ from the triangle of Q
CosQ = sqrt (5^2 - 4^2) / 5 = 3/5
Required = CosP + CosQ = 4/5 + 3/5 = 7/5

Sofia used colorful glass beads to make a
bracelet. She repeated the same pattern
of colored beads six times. If the length of
one pattern measures three fourths of an
inch in length, what is the total length of
the bracelet Sofia made?
Answer:
11.424cm
Step-by-step explanation:
3/4 of an inch = length of one pattern.
3/4 = 0.75 ( 1.905cm)
1.905 x 6 = 11.424cm
The total length of the bracelet Sofia made is 11.424 centimetres.
Note: I am not sure if this is completely right and meant to be in cm but I tried to help :)

Step-by-step explanation:
Starbucks Coffee Co. Uses a data-based approach to improving the quality and customer satisfaction of its products. When survey data indicated that Starbucks needed to improve its package-sealing process, an experiment was conducted to determine the factors in the bag-sealing equipment that might be affecting the ease of opening the bag without tearing the inner liner of the bag. (Data extracted from L. Johnson and S. Burrows, "For Starbucks, Itâs in the Bag," Quality Progress, March 2011, pp. 17â23. ) One factor that could affect the rating of the ability of the bag to resist tears was the plate gap on the bag-sealing equipment. Data were collected on 19 bags in which the plate gap was varied. The results are stored in Starbucks.
a. Construct a scatter plot.
b. Assuming a linear relationship, use the least-squares method to determine the regression coefficients b0 and b1.
c. Interpret the meaning of the slope, b1, in this problem.
d. Predict the mean tear rating when the plate gap is equal to 0.
e. What should you tell management of Starbucks about the relationship between the plate gap and the tear rating?
When there's a linear relationship, the least-squares method to determine the regression coefficients b0 and b1 will be y = 0.750 + 0.50x.
How to interpret the slope?The meaning of the slope, b1, in this problem is the coefficient of x which is the slope. Here, b1 = 0.50. It implies that one unit change in x will be 0.5 unit change in y.
To predict the mean tear rating when the plate gap is equal to 0 goes thus:
y = 0.75 + (0.05 × 0)
y = 0.75 + 0
y = 0.75
Lastly, the relationship between the plate gap and the tear rating is a positive one.

For triangle xyz , the measures of angles x,y, and Z are known. Which method should be used to start solving triangle xyz?
law of sines
law of cosines
neither law can be used
both laws can be used
Neither the laws of sines nor the law of cosines can be used to solve the triangle. The correct option is the third option - neither law can be used
Solving trianngles using the laws of sines & cosinesThe law of sines is written as
[tex]\frac{sinA}{a}=\frac{sinB}{b}= \frac{sinC}{c}[/tex]
Where a,b, and c are sides of any given triangle and A,B, and C are the angles.
This law is used when we are given either
Two angles and one side, orTwo sides and a non-included angleThe law of cosines is written as
a² = b² + c² -2bc cosA, or
b² = a² + c² - 2ac cosB, or
c² = a² + b² -2ab cosC
Where a,b, and c are sides of any given triangle and A,B, and C are the angles.
This law is used when we are given either
Three sides orTwo sides and the included angleNow, for triangle xyz, which the measures of angles X,Y, and Z are known, neither law can be used to solve the triangle.
Hence, neither the laws of sines nor the law of cosines can be used to solve the triangle. The correct option is the third option - neither law can be used

To find the area of a circle, take π x 2 x radius.
true or false
Answer:
That statement is true, but you do not always need the two.
Let's say that we had a problem, given the radius is 5, and we have to find the diameter.
First step is to define A
[tex]A = \pi r^2[/tex]
Second, redefine r as the actual radius to avoid confusion.
[tex]r = 5[/tex]
Third, set up an equation with the given values where you are multiplying pi by the radius.
[tex]\pi r^2 = \pi *r^2[/tex]
Fourth but not least, get the actual value.
[tex]\pi * r^2 = 79[/tex] rounded to nearest whole number
What is the equation of this line in slope-intercept form
Slope=
m=5+3/-1-1m=8/-2m=-4Equation in point slope form
y+3=-4(x-1)y+3=-4x+4y=-4x+1Answer:
[tex]y=-4x+1[/tex]
Step-by-step explanation:
We have been given two points on the line, so:
[tex]\textsf{let}\:(x_1,y_1)=(-1,5)[/tex]
[tex]\textsf{let}\:(x_2,y_2)=(1,-3)[/tex]
Calculate the slope using the slope formula:
[tex]\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-3-5}{1-(-1)}=-4[/tex]
From inspection of the graph, it appears that the y-intercept (where the line crosses the y-axis) is at (0, 1). However, just to be sure, use the point-slope form of linear equation.
Point-slope form of linear equation: [tex]y-y_1=m(x-x_1)[/tex]
(where m is the slope and (x₁, y₁) is a point on the line)
[tex]\implies y-5=-4(x-(-1))[/tex]
[tex]\implies y-5=-4x-4[/tex]
[tex]\implies y=-4x+1[/tex]
Therefore, the equation of the line in slope-intercept form is:
[tex]y=-4+1[/tex]

True or False: You can use the Pythagorean Theorem to determine if a triangle is a right triangle or not.
Answer:
True
Step-by-step explanation:
Definitely true. If the shorter legs of the given triangle are a and b and the longest side is c, then if a^2 + b^2 = c^2, the triangle is a right triangle. Otherwise it is not a right triangle.
at which point do the two equations 3x+5=y+4x and y=x2 intersect? problem is the picture below, the choices are there.
Answer:
A. and D.
Step-by-step explanation:
Hey there!
In order to to find the point at which these two equations intersect at, you need to first rewrite the equations if needed so that they are in the form:
[tex]y=mx+b[/tex]
or
[tex]y=ax^2+bx+c[/tex]
The first equations needs to be rewritten
[tex]3x+5=y+4x[/tex]
make [tex]y[/tex] by itself
[tex]3x+5-4x=y[/tex]
Simplify LHS
[tex]y=-x+5[/tex]
Now we have it in slope-intercept form
Looking at the equation, we can tell that the slope of the line is [tex]-1[/tex] and the y-intercept is 5
Now you can graph this equation easily (image down below)
The second equation is already in form so there is no need to rewrite anything
We can go straight to graphing (image down below)
Now plot both equations on the same graph (image down below)

1000x+27x+5.5=9236
Answer:
x = 8.98782862707
Step-by-step explanation:
Base on the given we can infer that we are solving for x:
Given equation:
1000x+27x+5.5=9236
Combine similar terms
1027x + 5.5 = 9236
Subtract both side by 5.5
1027x + 5.5 = 9236
-5.5 -5.5
-------------------------------------
1027x = 9230.5
Now divide both sides by 1027x
9230.5 / 1027
x = 8.98782862707
