Answer:
The range of the value of numbers is 8
Step-by-step explanation:
Mathematically, the range refers to the difference between the biggest and the smallest number
From the diagram, the biggest number is 13and the smallest is 5
The difference between this two is the range
we have this as 13 -5 = 8

The number of boxes in Warehouse "A" currently totaling 476 is increasing at a rate of 4 boxes per day. The number of boxes in Warehouse "B" currently totaling 986 is decreasing at a rate of 6 boxes per day. In how many days will these two warehouses contain the same number of boxes
Answer:
These two warehouses will contain the same number of boxes in 51 days.
Step-by-step explanation:
Since the number of boxes in Warehouse "A" currently totaling 476 is increasing at a rate of 4 boxes per day, while the number of boxes in Warehouse "B" currently totaling 986 is decreasing at a rate of 6 boxes per day, To determine in how many days these two warehouses contain the same number of boxes, the following calculation must be performed:
Warehouse A = 476 + 4X
Warehouse B = 986 - 6X
476 + 4 x 50 = 476 + 200 = 676
986 - 6 x 50 = 986 - 300 = 686
476 + 4 x 51 = 476 + 204 = 680
986 - 6 x 51 = 986 - 306 = 680
Therefore, these two warehouses will contain the same number of boxes in 51 days.
The point-slope form of the equation of the line that passes through (-9,-2) and (1,3) is y-3=1/2(x-1) what is the slope-intercept form of the equation for this line
Answer:
y = (1/2)x + 2 1/2
Step-by-step explanation:
y - 3 = (1/2)(x - 1)
Distribute the 1/2
y - 3 = (1/2)x - 1/2
Add 3 to both sides
y = (1/2)x + 2 1/2
Question
Patrick has 4 green hats, 3 blue hats, and 1 orange hat. If he selects a hat at random, what is the
probability of selecting a green hat?
.
0.4
O 0.5
O 0.8
Answer:
0.5
Step-by-step explanation:
First we need to find the total number of hats 4 green hats + 3 blue hats + 1 orange hat = 8 hats P( green hat) = green / total
= 4 / 8
= 1/2

Identify the missing parts in the proof.
Given: ∠ABC is a right angle.
DB bisects ∠ABC.
Prove: m∠CBD = 45°
A:
B:
C:
D:
Answer:
The missing parts of the proof includes;
1) ∠ABC = m∠CBD + m∠ABD = 90° (Angle addition postulate)
2) m∠CBD = m∠ABD (Definition of angle bisector)
3) m∠CBD + m∠ABD = m∠CBD + m∠CBD (Substitution property of equality)
Step-by-step explanation:
The given details of the proof are;
∠ABC is a right angle = 90°
Line DB is a bisector of ∠ABC
Therefore;
1) ∠ABC = m∠CBD + m∠ABD = 90° by angle addition postulate
By the definition of angle bisector, we have;
The angles formed by line DB from ∠ABC are equal,
2) m∠CBD = m∠ABD by the definition of angle bisector
3) m∠CBD + m∠ABD = 90° = m∠CBD + m∠CBD = 2 × m∠CBD by substitution property of equality
2 × m∠CBD = 90°
∴ m∠CBD = 90°/2 = 45°
Answer:
A: Given
B: measure the angle ABC = 90
C: angle addition postulate
D: 2 times the measure of angle CBD = 90

Circle T is shown. Line PS and line RS are tangent to circle T. What is the measure, in degrees, of angle PTR
0Answer:
Angle PTR is 136*
Step-by-step explanation:
In Question, We Have Given
Line PS and RS are Two Tangent To Circle With Centre T & ∠PSR=44* .
Thus ∠SPT=90* & ∠SRT=90* (Property Of Tangent ↔ Tangent always Form 90* With Radius Of Circle)
Now We Have A Quadrilateral SPTR & The Sum Of All Angle Of Quadrilateral is 360* .
Thus The Angle Of PTR is
∠PTR = 360* - ( 90*+90*+44*)
∠PTR = 360* - 224*
∠PTR = 136*

<6 = 109
<7 = 109
Step-by-step explanation:
Angles 6 and 7 are vertical angles so they are equal
7x -24 = 5x+14
Subtract 5x from each side
7x-5x -24 = 5x-5x+14
2x-24 = 14
Add 24 to each side
2x-24 +24 = 14+24
2x = 38
Divide by 2
2x/2 = 38/2
x = 19
<6 = 7x -24 = 7*19 -24 = 109
<7 = 5(19)+14 = 109
quadrilateral BANK is a parallelogram. if AB= 10cm and AN= 6cm, what is the length of NK?
guys patulong, thanks!
Answer:
The length of NK is 10 cm.
Answer:
10 cm
Step-by-step explanation:
In parallelogram, opposite sides are parallel and equal.
AB and NK are opposite sides
So, NK = AB = 10cm

A circle has a circumference of 616 cm.
What is the approximate radius of the circle? (Use 22/7
as an estimate for pi.)
A 14 cm
B. 49 cm
C. 98 cm
D. 196 cm
Answer:
π =14 cm
Step-by-step explanation:
Given:
circumference of a circle =616 cm
pie(π)=22/7
circumference of a circle=πr^2
616=22/7 *r^2
616*7/22 =r^2
4312/22 =r^2
196=r^2
[tex]\sqrt{196}[/tex] =r

Step-by-step explanation:
[tex]5x + 3y = 13 \\ 7x + 8y = - 16 \\ 5x = 13 - 3y \\ x = \frac{13 - 3y}{5} \\ 7( \frac{13 - 3y}{5} ) + 8y = - 16 \\ 18.2 - 4.2y + 8y = - 16 \\ 3.8y = - 34.2 \\ y = - 9 \\[/tex]

Subtract the given polynomials using the vertical format.
===========================================
Explanation:
The negative out front of the parenthesis will swap the sign of each term. That means -3c^3 becomes +3c^3, or simply 3c^3. The other terms in the parenthesis are handled the same way.
After distributing the negative through, we add straight down.
The 7c^3+3c^3 becomes 10c^3
Then we have -5c^2+(-2c^2) become -7c^2
Finally, 2c+2c simplifies to 4c
Answer:
10C³-7C²+4C
7c³-(-3c³) -5c²-(+2c²) +2c-(-2c)
