Luis plans to purchase some new baseball bats and gloves before spring training begins. Luis wants to buy the same bats and gloves he purchased last spring, but he can’t remember the price of each item. Luis recalls making two purchases last spring, each totaling $135 and both tax exempt. The first purchase was for a glove and three bats. The second purchase was for two gloves and a bat. If the current prices of these items are the same as last spring, how much will Luis pay this spring for three gloves and four bats?
Answer:
Luis will pay for three gloves and four bats = $ 270
Step-by-step explanation:
Let the bats be represented by b and gloves by g, then according to the given conditions
3b+ g= $135----equation 1
b+ 2g= $135------equation 2
Subtracting equation 2 from eq. 1 gives
3b+ g= $135----equation 1
-b -2g= -$135------equation 2
2b -g = 0 --------- equation3
2b-g= 0
or 2b= g------ equation4
This means price of 2 bats is equal to price of 1 glove.
Putting value of g in eq. 1 from eq. 4
3b+ 2b= $ 135
5b= $135
b= 135/5= 27
Price of 1 bat = $ 27 and price of 1 glove= 2*27= $54
Luis will pay for three gloves and four bats
= 54*3 + 4*27
= 162+ 108
= $ 270

In circle T with m∠STU=78 and ST=8 , find the length of arc SU. Round to the nearest hundredth.
Answer:
10.89
Step-by-step explanation:
The length of the arc SU in the circle T is 10.88 units.
What is circle?A circle is a shape or a curve in a plane that has a fixed distance, called the radius, from a given point, called the centre.
Given that, in a circle T, m ∠STU = 78° and ST = 8, we need to find the length of arc SU,
The length of an arc = central angle / 360° × perimeter
= 78° / 360° × 3.14 × 16
= 10.88
Hence, the length of the arc SU in the circle T is 10.88 units.

an airship flies 150 km with the wind and then turn around and flies back taking 5 hour and 30 min round trip. Find the speed of the airship in calm weather is 55 mph.
Answer:
150=(55-c)(5.5-t)
5.5-t=150/(55-c)
-t=(150-302.5+5.5c)/(55-c)
t=(152.5-5.5c)/(55-c)
150=(55+c)t using t found about
150=(55+c)(152.5-5.5c)/(55-c)
8250-150c=8387.5-302.5c+152.5c-5.5c^2
5.5c^2=137.5
c^2=25
c=5
So the current is 5mph.

Define angle bisector.An angle bisector is defined as a ray, segment, or line that bisects a given angle into two equal angles. The word bisection or half means dividing one object into two equal or identical parts. In geometry, we usually divide triangles and angles by lines or lines that are considered bisectors.
A geometric bisector is a ray, line, or segment that divides a given angle into two equal parts. For example, the bisector of a 60 degree angle divides it into two 30 degree angles. In other words, split the angle into two smaller congruent angles.
For the given case,
Ray BD bisects ∠ABC into two equal angles ∠ABD and ∠DBC; which can be written as ∠ABD = ¹/₂ ∠ABC.

How many pieces of wire 3.6cm long can be cut from a coil of 1m long?What is the length of the piece left over?
Answer:
We can get 27 pieces of wire 3.6 cm long and have a piece 7/9 cm left over
Step-by-step explanation:
Find the "unit length" by dividing 1 m by 3.6 cm:
1 m
-----------
3.6 cm
Recall that 1 m = 100 cm. Multiply the following by the conversion factor 100 cm / 1 m:
1 m 100 cm
----------- * ----------------- = 27,7777777...
3.6 cm 1 m
We can get 27 pieces of wire 3.6 cm long and have a piece 7/9 cm left over (verify this by dividing 7 by 9 on a calculator).
Answer:
Solution :-Pieces can be cut = 1/3.6
Pieces can be cut = 0.27 m
100 cm = 1 m
0.27 m = 27 cm
Therefore,
The length remaining of wire is 27 cm (approximately)

Which statements are true about the toolbox? Select two options.
The shape can be broken into a rectangular prism and a triangular prism.
The shape can be broken into a rectangular prism and a rectangular pyramid.
The formula for the volume of this figure is V = B h + one-third B h.
The volume of the toolbox is 840 inches cubed
The volume of the toolbox is 900 inches cubed
Answer:
Option A and E.
Step-by-step explanation:
It is mentioned that Chiyo has a toolbox having a rectangular prism shape with a length of 8 inches, width of 15 inches, and height of 6 inches.
In addition to this, A triangular prism with a triangular base with base 8 inches and height 3 inches. The prism has a height of 15 inches.
So here the shape can be broken into a triangular prism and rectangular prism
Therefore the first option is correct
Now as we know that
Volume of the rectangular prism is
= l×b× h
= 8 × 15 × 6
= 720
And, the volume of the triangular prism is bh
And, the area of the triangular prism is 1 ÷ 2 × b × h
= 1 ÷ 2 × 8 × 3
= 12
Now the volume is
= 12 × 15
= 180
So, the volume of the tool box is
= 720 + 180
= 900
Hence, the last option is correct
