answer:
8. 67 and 17. 36
step-by-step explanation:
hi there!
to find out the age of both girls, i believe that we should divide the number 26 by 3 because jamie is twice as old as natalie meaning ( natalie ) is younger
26/3
= 8. 67
meaning 8.67 is how old natalie is/was
add 8.68 to itself once and you will get jamie's age!
8. 67 + 8. 67
= 17. 34
meaning 17. 34 is how old jamie is/was
sorry if i misread the question or made it a little confusing! but i do hope that this ends up helping you! :)

Answer:
15π cubic units
Step-by-step explanation:
the formula for the volume of a cone is:
V = (base area x height) / 3
In this case we have
(5π x 9)/3 = 15π cubic units
Answer:
235.5 Cubic Units
Step-by-step explanation:
V=1/3B*H
=1/3(π5^2)9
=1/3(3.14*25)9
=3(3.14*25)
=75*3.14=235.5 Cubic Units
Estelle tried to evaluate the expression 27 - (8 - 3) x 4. Here is her work:
27 - (8 - 3) x 4
= 27 - 5 x4
Step 1
= 22 x 4
Step 2
= 88
Step 3
Is Estelle's work correct?
No, Estelle made a mistake in Step 1. Estelle should have multiplied instead of
subtracting. The order of operations says to multiply before you subtract.
No, Estelle made a mistake in Step 2. Estelle should have multiplied before
she subtracted. The order of operations says to multiply before you subtract.
Yes, Estelle's work is correct.
Answer:
No, Estelle made a mistake in step 2
Step-by-step explanation:
The parent function of a quadratic equation is vertically stretched by a factor of 2, then translated 4 units left and one unit down
Answer:
[tex]f"'(x) = 2(x-4)^2 - 1[/tex]
Step-by-step explanation:
Given
[tex]f(x) = x^2[/tex] --- the quadratic function
Vertically stretched by 2
Translation: [tex]4\ units[/tex] left and [tex]1\ unit[/tex] down
Required
Determine the new function
[tex]f(x) = x^2[/tex]
The rule for vertical stretch is:
[tex](x,y) \to (x,ay)[/tex]
In this case:
[tex]a = 2[/tex]
So, we have:
[tex]f(x) = x^2[/tex]
[tex]f'(x) = a * f(x)[/tex]
[tex]f'(x) = a * x^2[/tex]
Substitute: [tex]a = 2[/tex]
[tex]f'(x) = 2 * x^2[/tex]
[tex]f'(x) =2x^2[/tex]
Translation: 4 units left
The rule is:
[tex](x,y) \to (x - c,y)[/tex]
In this case: [tex]c =4[/tex]
So, we have:
[tex]f"(x) = 2(x - 4)^2[/tex]
Translation: 1 unit down
The rule is:
[tex](x,y) \to (x,y-d)[/tex]
In this case, [tex]d=1[/tex]
So, we have:
[tex]f"'(x) = f"(x) - 1[/tex]
[tex]f"'(x) = 2(x-4)^2 - 1[/tex]

Practice Triangle Ratios (Sides) Find the value of c. Round to the nearest tenth!
Answer:
30.67
Step-by-step explanation:
Given the following
Opposite side = x
Adjacent = 17
Angle = 61degrees
Using the SOH CAH TOA identity
tan theta = opp/adj
tan 61 = x/17
x = 17tan61
x = 17(1.8040)
x = 30.67
Hence the value of x is 30.67
A XYZ is an equilateral triangle.
X
2
3
Z
Y
What is the measure of Z 2?
HURRY AND NO LINKS
Answer:
The value of the angle is 60 degrees
Step-by-step explanation:
Here, we want to find the value of the angle marked 2
From the question, we can see that we have three marked interior angles
These are the angles 1, 2 and 3
Mathematically, the interior angles of an equilateral triangle are equal
This means that each of the interior angle of an equilateral triangle measures 60 degrees
Hence, this means that the value of the angle marked 2 is 60 degrees
Approximately 3 x 10° people live in the USA.
In the world of 100 people, how many would live in the USA?
Answer:
Step-by-step explanation:
Divide the US population by the world population:
328,200,000/7,674,000,000 = 0.0428
Multiply 0.0428 with 100:
0.0428 x 100 = 4.28
Approximately 4 out of 100 people in the world would live in the USA.

Answer:
40 degrees
Step-by-step explanation:
Answer:
Angle E = 25 deg because of reflective
Angle C = 115 degree because 180 - 65
Since triangle = 180 deg
Angle D = 180 - 115 - 25
= 40 deg

Find the value of x.
A small car has a tire with a 13-inch diameter. A truck has a tire with a 29-inch diameter. How much farther than the car does the truck have to drive for its tire to complete one revolution?
Answer:
50.27in
Step-by-step explanation:
Given data
Diameter of small tire= 13in
Radius= 13/2= 6.5in
Circumference= 2πr
C= 2*3.142*6.5
C= 40.85 in
Diameter of Big tire= 29in
Radius= 29/2= 14.5in
Circumference= 2πr
C= 2*3.142*14.5
C= 91.118in
Hence the difference in distance between the two tires after on revolution is
=91.118-40.85
=50.27in

Baking Brownies
A brownie recipe needs one cup of sugar for every 1⁄2 cup of flour to make a batch of cookies. To make multiple batches, we represent the relationship between flour and sugar with the function f = 1⁄2 s where f is the number of cups of flour and s the number of cups of sugar. What graph represents this relationship?
Answer:
A
Step-by-step explanation:
A because it is the only one the recipe calls for 1 cup of sugar and 1/2 cup of flour, the point is in the middle but also on one.
