A toymaker was making trucks to sell in his
shop. He made three times as many four-
wheeled trucks as six-wheeled trucks,
He used 54 wheels altogether
How many four-wheel and
siy-wheel trucks did he make?
Answer: 9 Four Wheel and 3 6 Wheel Trucks
Step-by-step explanation:
Let FW be the four-wheel trucks and SW the six-wheel trucks.
Total wheels is 4*FW + 6*SW and is equal to 54 wheels
We know that FW = 3*SW, so substitute that into the above equation:
4*3*SW + 6*SW = 54
12*SW +6*SW = 54
18*SW = 54
SW = 3
Therefore FW = 3*3 = 9
FW 4 x 9 = 36 wheels
SW 6 x 3 = 18 wheels
Total = 54 wheels

49q²-70q+25 resolve into fractors
Answer:
(7q-5)²
Step-by-step explanation:
= 49q² - 70q + 25
= 49q² -35q -35q + 25
= 7q(7q-5) - 5(7q - 5)
= (7q-5) (7q-5)
= (7q-5)²
CMIIW
Answer:
Step-by-step explanation:
49q² -70q +25 , rewrite the first two terms as squares
(7q)² -70q + 5² , compare with a² - 2ab + b² = (a-b)²
a² - 2ab + b²
(7q)² -2(7q)(5 )+ 5², because 70q = 2*35q = 2*7*5*q
We can see that a = 7q and b=5, therefore
49q² -70q +25 = (7q -5)²
We set the equation equal to 0 to find the roots
7q-5 =0, add 5 to both sides
7q =5 , divide both sides by 7
q = 5/7 ≈ 0.714
Please help me with number 4.
help me please and thank u
[tex]\large \mathfrak{Solution : }[/tex]
As we know :
Dividend = Divisor × Quotient ( taking remainder as 0 )
So, Quotient = Dividend ÷ Divisor
by using the above relation we can say :
q = t ÷ 23therefore, correct option is C. t ÷ 23

The x-axis shows Craig's pitch speed in miles per hour.
The highest speed he did was between 70 to 75 mph. Craig's doesn't specify the speed in the histogram, so we can only be sure that Craig's fastest is between 70 to 75 mph.

Answer:
6.25YEARS
Step-by-step explanation:
S.I.=P×R×T÷100
T=S.I.×100÷P×R
T=500×100÷2000×4
T=500÷20×4
T=500÷80
T=6.25 YEARS

find the unknown angles
Answer:
Step-by-step explanation:
∠WZA + WZY = 180 {linear pair}
88 + ∠WZY = 180
∠WZY = 180 - 88
∠WZY = 92°
∠WXY + ∠WZY = 180 {Opposite angle in cyclic quadrilateral}
x + 92 = 180
x = 180 - 92
x = 88°

The line joining (3, p) to (7, –4p) is parallel to the line joining (–1, –3) to (3, 7). Find p.
Answer:
p = - 2
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 1, - 3) and (x₂, y₂ ) = (3, 7)
m = [tex]\frac{7-(-3)}{3-(-1)}[/tex] = [tex]\frac{7+3}{3+1}[/tex] = [tex]\frac{10}{4}[/tex] = [tex]\frac{5}{2}[/tex]
Parallel lines have equal slopes
Calculate the slope of the other 2 points and equate to [tex]\frac{5}{2}[/tex]
with (x₁, y₁ ) = (3, p) and (x₂, y₂ ) = (7, - 4p)
m = [tex]\frac{-4p-p}{7-3}[/tex] = [tex]\frac{-5p}{4}[/tex] = [tex]\frac{5}{2}[/tex] ( cross- multiply )
- 10p = 20 ( divide both sides by - 10 )
p = - 2
sandra has 4 math test this marking period. she recieved 90%, 87%. and 92% on the first three. what is the minimum score she needs on her last test in order to average atleast a 90% in math class?

[tex] \dfrac{46}{5.2} [/tex][tex] \dfrac{46 \times 10}{52} [/tex][tex]8.8461538462 \approx8.8[/tex]Answer: 0.113
Step-by-step explanation: 46 divided by 5 = 0 next put a 5 next to the 2 46 divided by 5.2 = 1 then there was six left over so put a six next to the 0 46 divided by 60 = 1 then there is 14 left over so put a 14 next to the 0 46 divided by 140 = 3
So the answer is 0.113 hope that answer helped you

Answer:
4+9= 13
Step-by-step explanation:
The sun is 1.5 x 10^11 m from earth.
Express this distance with an SI prefix.
Answer:
First, we write the SI prefixed. The SI unit for distance is meters.
Kilo = 10³
Mega = 10⁶
Giga = 10⁹
Terra = 10¹²
Because our value has ten to the power of 11, we will use the closest and lowest power prefix, which is giga.
1.5 x 10¹¹ / 10⁹
= 1.5 x 10² Gm or 150 Gm
Writing in kilometers, we simply repeat the procedure except we divide by 10³ this time.
1.5 x 10¹¹ / 10³
= 1.5 x 10⁸ km
Step-by-step explanation:
First, we write the SI prefixed.
The SI unit for distance is meters.
Kilo = 10³
Mega = 10⁶
Giga = 10⁹
Terra = 10¹²
Because our value has ten to the power of 11, we will use the closest and lowest power prefix, which is giga.
1.5 x 10¹¹ / 10⁹
= 1.5 x 10² Gm or 150 Gm
Little more explanation : In scientific notation, if the exponent of 10 is positive, the number is very very large. In the metric system, very large numbers are expressed in megameters (Mm) or gigameters (Gm). Gigameters is equal to 10⁹ meters. So, in SI prefix, that would be equal to 150 Gm. In kilometers, that would be equal to:
1.5×10¹¹ m * (1 km/1000 m) = 1.5×10⁸ km
