Answer:The Rule for 10: Numbers that are divisible by 10 need to be even and divisible by 5, because the prime factors of 10 are 5 and 2. Basically, this means that for a number to be divisible by 10, the last digit must be a 0. ... So this number is even and divisible by 5. That means that it is also divisible by 10

Solve the equation by completing the square. X^2+10x+24=0
Answer:
x = -4
x = -6
Step-by-step explanation:
X^2+10x+24=0
(b/2)^2 = (10/2)^2 = 25
X^2+10x+25=-24+25
(x+5)^2 = 1
(x+5) = ± 1
x = +1 -5 = -4
x = -1 -5 = -6

Answer:
P is complementary to x
Step-by-step explanation:
Complementary means adding to 90 degrees
P+x = 90 degrees
So P is complementary to x
Answer:
( A) ∠ P
∠P is complementary angle to ∠ X .
Step-by-step explanation:
Sum of two angles of complementary angle is 90° .∠P and ∠X sum of both angles is 90°.So, they are complementary angle.P + X = 90°
P is complementary to X.
This graph shows the amount of money Leo earns from tutoring compared with the number of hours he works. Select the correct statement about the graph.
A. For each hour he works, his earnings go up by $7.
B. For each hour he works, his earnings go up by $14.
C. For every 7 hours he works, his earnings go up by $1.
D. For each dollar he earns, the number of hours he works goes up by 14.
Answer:
B. For each hour he works, his earnings go up by $14.
Step-by-step explanation:
Given
The attached graph
Required
The true statement
The attached graph is a linear graph.
From the graph, we have:
[tex](x_1,y_1) = (0,0)[/tex]
[tex](x_2,y_2) = (1,14)[/tex]
The rate (m) is:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{14-0}{1-0}[/tex]
[tex]m = \frac{14}{1}[/tex]
[tex]m = 14[/tex]
This implies that the hourly rate is $14/hr
Hence (b) is true

If the Circumstance of wobble ball is 242cm what is the surface area?
Answer:
1,166 is the SA
correct me if im wrong somehow
Step-by-step explanation:
a wobble ball is a sphere
circumference=8(pi)
242=8(3.14)
so 242 divided by 25.12
this ends up with 9.633757961783439, which is the radius of the circumference
SA of a sphere= 4(pi)r²
SA=4(3.14)9.633757961783439²
SA=4(3.14)92.80929246622581
SA=1,165.684713375796
rounded to the nearest whole # = 1166
Water runs from a faucet into a bucket at a steady rate. After 4 seconds, there are 32 ounces of water in the bucket. Write an equation that shows the relationship between time and ounces of water. Use t for time in seconds and w for ounces of water.
9514 1404 393
Answer:
w = 8t
Step-by-step explanation:
If we assume that the ounces of water are proportional to the time, then the equation will look like ...
w = kt
for some constant k.
Solving for k, we find ...
k = w/t
Using the given values, we find k to be ...
k = (32 ounces)/(4 seconds) = 8 ounces/second
The units are stated in the definitions of the variables, so we can write the equation as ...
w = 8t
Which of the following is a point-slope equation of a line that passes through the points (-1, 4) and (8,-2)?
A. y-4= -3/2(x+1)
B. y-4= -2/3(x+1)
C. y-4= 2/3(x+1)
D. y-4= -2/3(x-1)
Answer:
B
Step-by-step explanation:
We want to find the point-slope equation of a line that passes through the points (-1, 4) and (8, -2).
Point-slope form is given by:
[tex]y-y_1=m(x-x_1)[/tex]
Where m is the slope and (x₁, y₁) is a point.
So, let's find the slope of the line first. We can use the slope formula:
[tex]\displaystyle m=\frac{\Delta y}{\Delta x}=\frac{-2-4}{8-(-1)}=\frac{-6}{9}=-\frac{2}{3}[/tex]
We can choose (-1, 4) as our point. So, (x₁, y₁) = (-1, 4).
Substitute:
[tex]\displaystyle y-(4)=-\frac{2}{3}(x-(-1))[/tex]
Simplify:
[tex]\displaystyle y-4=-\frac{2}{3}(x+1)[/tex]
Therefore, our answer is B.

For a process, the average range for all samples was 5 and the process average was 25. If the sample size was 10, calculate UCL for the R-chart.
Answer:
8.885
Step-by-step explanation:
Given that :
Sample size, n = 10
The average range, Rbar for all samples = 5
The upper control limit, UCL for the R-chart is :
UCL L= D4Rbar
From the control chart constant table, D4 = 1.777
Hence,
UCL = 1.777 * 5
UCL = 8.885
The UCL for the R-chart is 8.885

Put the numbers in the equation and do the arithmetic.
1/R = 1/(3 1/2) +1/(5 1/4)
1/R = 1/(7/2) +1/(21/4) = 2/7 +4/21 = (6 +4)/21

Step-by-step explanation:
h = x
p = 10
b = 24
using pythagorean theorem
h² = p² + b²
h² = 10² + 24²
h² = 676
h = 26
thus , x = 26
Answer:
x = 26
Step-by-step explanation:
use the Pythagorean theorem
[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
[tex] {10}^{2} + {24}^{2} = {c}^{2} [/tex]
[tex] = 676 = {c}^{2} [/tex]
[tex]c = \sqrt{676} [/tex]
c = 26

This graph represents a quadratic function. What is the function's equation written in factored form and in vertex form?
(graph in picture)
Step-by-step explanation:
f(x) = a(x-x1) (x-x2)
from the vertex, we get a:
0 = a(4-2)²- 8
4a = 8
a = 2
so, the equation:
f(x) = 2(x-0) (x-4)
f(x) = 2x(x-4)
f(x) = 2x² -8x

PLEASE HELP ME!! Kevin earns a base salary of $350.00 every week with an additional 12%
commission on everything he sells. If Kevin sold $4950.00 worth of items
last week, what was his total pay?
============================================================
Explanation:
He sold $4950 worth of items. Take 12% of this amount to get
12% of 4950 = 0.12*4950 = 594
So he earns $594 in commission on top of the $350 base salary paid every week. In total, he earns 594+350 = 944 dollars for that week
This isn't the per week pay because he would need to sell exactly $4950 worth of goods each week to keep this same weekly pay.

Answer:
(a) 260 square centimeters
Step-by-step explanation:
The figure consists of a 10 cm square and four congruent triangles with base 10 cm and height 8 cm. Using the formulas for the area of a square and a triangle, the total area is ...
area = square area + 4 × triangle area
area = s² + 4×(1/2bh) = (10 cm)²+ 2(10 cm)(8 cm) = (100 +160) cm²
area = 260 cm²
Can y’all help me solve this question it’s due by the end of the day and I’m failing math?explain it plz
Answer:
x=4 and y=−4
Step-by-step explanation:
Let's solve your system by elimination.
−x−2y=4;3x+2y=4
−x−2y=4
3x+2y=4
Add these equations to eliminate y:
2x=8
Then solve 2x=8 for x:
2x=8
2x
2
=
8
2
(Divide both sides by 2)
x=4
Now that we've found x let's plug it back in to solve for y.
Write down an original equation:
−x−2y=4
Substitute 4 for x in−x−2y=4:
−4−2y=4
−2y−4=4(Simplify both sides of the equation)
−2y−4+4=4+4(Add 4 to both sides)
−2y=8
−2y
−2
=
8
−2
(Divide both sides by -2)
y=−4
