AABC has vertices A(1,3), B(2,5), and C(5,3). What are the coordinates of B' after
the translation by the vector <1,4>? (Give your answer as an ordered pair without spaces.)
Answer:
The coordinates of point B' are (3, 9)
Step-by-step explanation:
If the point (x, y) translated by a vector <a, b>, then its image is (x + a, y + b)
Let us use this rule to solve the question
In Δ ABC
∵ The coordinates of vertex A are (1, 3)
∵ The coordinates of vertex B are (2, 5)
∵ The coordinates of vertex C are (5, 3)
∵ Δ ABC is translated by the vector <1, 4>
→ By using the rule above add the x-coordinate of point B by 1
and the y-coordinate of point B by 4
∴ B' = (2 + 1, 5 + 4)
∴ B' = (3, 9)
∴ The coordinates of point B' are (3, 9)
which ordered pair is a solution of the equation: 2y=7x-3
only 2,4
only 3,9
both 2,4 and 3,9
neither
Answer:
It is only 3,9.
Step-by-step explanation:
You need to substitute each pair into the equation to find if both side have the same answer, 3,9 is the correct answer because both sides are equal:
2(9) = 7(3)-3
18= 18
The answer is (3,9).

helpppppppppp plz its no 8t^6
Answer:
u tried -8t^6???
Step-by-step explanation:
because -*+= -
Answer: -8t^6
Step-by-step explanation:
You just have to multiply the 2 and -4 which would give you -8. Then add the two exponents and you would get a 6.
Jerry scored 581 points by collecting 7 coins. In all, how many coins does Jerry have to collect to score a total of 996 points? Solve using unit rates.
Answer:
12 coins
Step-by-step explanation:
Points scored by collecting 7 coins = 581
Number of coins required to collect 996 points
Let Number of coins = c
7 coins = 581 points
c coins = 996 points
Cross multiply :
581 * c = 996 * 7
581c = 6972
Divide both sides by 581
581c / 581 = 6972 / 581
c = 12
Hence, number of coins required to collect 996 points is 12

Sandra hikes 9/10 mile every 30 minutes,or 1/2 hour. How many miles does she hike each hour?
9514 1404 393
Answer:
1.8 miles
Step-by-step explanation:
In the first half hour, Sandra hikes 9/10 = 0.9 miles. She hikes that distance again in the second half-hour. After an hour, Sandra has hiked ...
2 × 0.9 miles = 1.8 miles
__
If you like, you can consider it a "unit rate" problem. To find miles per hour, divide miles by hours:
(9/10 mi)/(1/2 h) = (9/10)(2/1) mi/h = 9/5 mi/h = 1.8 mi/h
Sandra hikes 9/5 or 1.8 miles in an hour.
What is the volume of a square pyramid that is 60 m on each side of its base and has a height of 100 m round to the nearest 10th
Answer:
Volume of square pyramid=120,000 m³
Step-by-step explanation:
We are given: Base of square pyramid = 60 m
Height of square pyramid = 100 m
We need to find Volume of square pyramid.
The formula used is: [tex]Volume \ of \ square \ pyramid=\frac{1}{3}a^2h[/tex]
Where a is base and h is height of square pyramid
Putting values in formula and finding volume of square pyramid
[tex]Volume \ of \ square \ pyramid=\frac{1}{3}a^2h\\Volume \ of \ square \ pyramid=\frac{1}{3}(60)^2(100)\\Volume \ of \ square \ pyramid=\frac{1}{3}(3600)(100)\\Volume \ of \ square \ pyramid=120,000\ m ^3[/tex]
So, Volume of square pyramid=120,000 m³

Evaluate the algebraic expression for v= 1 and r = 7
6r - |-8+v|
Answer:
41
Step-by-step explanation:
The absolute value function always gives a positive result, that is
| - a | = | a | = a
Given
6r - | - 8 + v | ← substitute v = 1 and r = 7 into the expression
= 6(7) - | - 8 + 1 |
= 42 - | - 1 |
= 42 - 1
= 41
A store sells toys in bulk. It sells wooden blocks for $5 a pound and plastic bricks for $10
a pound. How many pounds of wooden blocks and plastic bricks should be used to make a
10-pound mixture that would sell for $80?
9514 1404 393
Answer:
6 # plastic bricks4 # wooden blocksStep-by-step explanation:
Let p represent the number of pounds of plastic bricks in the mix. Then the number of pounds of wooden blocks is (10-p), and the total cost is ...
10p +5(10-p) = 80
5p = 30 . . . . . . . . . subtract 50
p = 6 . . . . divide by 5; there are 6 pounds of plastic bricks in the mix
4 pounds of wooden blocks and 6 pounds of plastic bricks should be used to make a 10-lb mix worth $80.
Jimmy and Lauren are
organizing transportation for
a field trip from ACIT. Jimmy
found out that his group has
841 students, and he needs 9
vans and 16 buses to
accommodate. While Lauren’s
group has 351 students, and
she needs 8 vans and 5 buses
for them. How many students
fit in a van and a bus for this
field trip? (please include steps)
Step-by-step explanation:
Jimmy's group : has 841 students
Lauren's group: has 351 students
9 vans 16 buses
8 vans 5 buses
Vans: V
Buses: B
9v + 16b = 841
9v + 16b = 841
-16b -16b
9v/ 9 = 841 /9 - 16b/9
8( 841/9 - 16b/9) +5b = 351
v - (841/ 9 - 16b / 9 )
8 (841 / 9 - 16b/9) +5b = 351
6728/9 - 128b / 9 +5b = 351
-128b/9 + 45b/9 = -83/9b
6728/9 -83/9
- 6728/9 +83/9 = 3159/9 - 6728/9
(9)83b / 9 = -3569 (9)/9
-83b = -3564
-83 -83
B = 43 students
8v + 5b = 351
8v + 5 (43) = 351
8v + 215 = 315
-215 -215
8v = 136
8 8
V = 17 students
43 students can fit on a bus and 17 students can fit in a van.

1 1/2 x 12
Key: Keep, change, flip.
So 1 1/2 you have to make it into a improper fraction.
1 1/2 to 3/2 x 12/1 = 3/2 x 1/12 = 1/2 x 1/4 = 1/8

A dance team is going to spend $1,440 to purchase all sweatshirts or all jackets for the team members. Sweatshirts cost $24 each. Jackets cost $32 each. What is the greatest number of sweat- shirts or jackets the team can purchase?
Answer:
60 sweatshirt
Or
45 jackets
Step-by-step explanation:
Total amount = $1,440
Sweatshirts = $24
Jackets = $32
What is the greatest number of sweat- shirts or jackets the team can purchase?
The greatest number of sweat- shirts the team can purchase = Total amount / cost of sweatshirt
= $1,440 / $24
= 60
The greatest number of jackets the team can purchase =Total amount / cost of jackets
= $1,440 / $32
= 45
Therefore, the greatest number of sweat- shirts or jackets the team can purchase is
60 sweatshirt
Or
45 jackets
Answer:
45 or 60

Step-by-step explanation:
Use Δ ABC to find AB then Δ ABD to find DB
Δ ABC is isosceles since ∠ CAB = ∠ CBA = 45° , then CB = CA = 2
Using Pythagoras' identity in Δ ABC , then
AB² = 2² + 2² = 4 + 4 = 8 ( take square root of both sides )
AB = [tex]\sqrt{8}[/tex] = 2[tex]\sqrt{2}[/tex]
----------------------------------------------------------------
Using the sine ratio in Δ ABD with the exact value
sin60° = [tex]\frac{\sqrt{3} }{2}[/tex] , then
sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AB}{DB}[/tex] = [tex]\frac{2\sqrt{2} }{DB}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )
[tex]\sqrt{3}[/tex] × DB = 4[tex]\sqrt{2}[/tex] ( divide both sides by [tex]\sqrt{3}[/tex] )
DB = [tex]\frac{4\sqrt{2} }{\sqrt{3} }[/tex] ( multiply numerator/ denominator by [tex]\sqrt{3}[/tex] to rationalise denominator )
= [tex]\frac{4\sqrt{2} }{\sqrt{3} }[/tex] × [tex]\frac{\sqrt{3} }{\sqrt{3} }[/tex]
= [tex]\frac{4\sqrt{6} }{3}[/tex] → C

The ratio of the present age of mother and daughter is 3:1. Six years ago the ratio of their age was 6 : 1. Find their present age.
Answer:
30 and 10
Step-by-step explanation:
Given ratio of age = 3 : 1 = 3x : x ( x is a multiplier )
Six years ago their age ratio was
3x - 6 : x - 6 = 6 : 1 ← express in fractional form
[tex]\frac{3x-6}{x-6}[/tex] = [tex]\frac{6}{1}[/tex] ( cross- multiply )
6(x - 6) =3 x - 6
6x - 36 = 3x - 6 ( subtract 3x from both sides )
3x - 36 = - 6 ( add 36 to both sides )
3x = 30 ( divide both sides by 3 )
x = 10
Thus their present ages are
mother = 3x = 3 × 10 = 30
daughter = x = 10

Step-by-step explanation:
For every 1 litre of water used to make a medicine, 150 ml of sucrose and 600ml of saline solution are used. Express the amount of water, sucrose and saline solution needed as a ratio in its simplest form.
Quantity of water used to make a medicine :-
[tex]= \texttt{1 \: litre }[/tex]
[tex] =\texttt{ 1×1000 \: ml}[/tex]
[tex] =\texttt{\color{hotpink} 1000 \: ml}[/tex]
This quantity of water required to make a medicine = 1000 ml
Quantity of sucrose used to make a medicine = 150 ml
Quanity of saline solution used to make a medicine = 600 ml
The quantity of water to sucrose to saline solution needed to make a medicine as a ratio :-
[tex] = \texttt{1000 : 150 : 600}[/tex]
Cutting each common zero in this ratio, we get :-
[tex] = \texttt{100 : 15 : 60}[/tex]
Dividing each number in the ratio by 5, we get the ratio :-
[tex] =\texttt{ \color{hotpink}20 : 3 : 12}[/tex]
Since, the three numbers in this ratio doesn't have any common factors we can conclude that we have found out the simplest form of the ingredients needed to make the medicine .
Therefore, the ratio of water to sucrose to saline solution needed to make a medicine = 20:3:12
