Answer:
The first option:yellow shirt, white trouseryellow shirt, black trousergreen shirt, white trousergreen shirt, black trouserStep-by-step explanation:
To find the possibilities, you would see that you would have two yellow shirts and two green shirts with different trousers, so you can eliminate the bottom two. And because there will be two of each shirt with defferent trousers, it will be the same for trousers: two of each trouser will be in the possibilities. The only one that fits this description, is the first one.

The product of two consecutive even integers is 6 more than 3 times their sum. The integers are: a. 6,8 b. 16, 20 12, 16 d. 20, 24 C.
Answer:
a. 6,8
Step-by-step explanation:
The only offered answer choice that lists consecutive even integers is ...
a. 6,8
_____
Consecutive even integers differ by 2, not 4.
__
Check
The product is 6×8 = 48.
Three times the sum is 3(6+8) = 3(14) = 42.
The product is 6 more than 3 times the sum. 42+6 = 48
A 16" × 16" square tray can hold at most 9 bagels placed side by side, as shown below. At most how many bagels can a 32" × 32" square tray hold if bagels are placed side by side?\
Answer:
At most it can hold 18 bagels
Step-by-step explanation:
So we can make this an equation
16 · 16 square tray = 9 bagels on top of it
We just doubled both sides of it
giving us 32 · 32 square tray = 18 bagels can be held.
From 8:00 am to 8:20 am, Lisa picked 1/4 of a pound of strawberries. If she continues picking strawberries at this rate, how many pounds of strawberries will she pick in 4 hours?
Answer:
3 lbs
Step-by-step explanation:
20 mins is 1/4 lb (4oz)
1 hr is 3/4 lb (12 oz)
4 hrs= 3/4 lb or 12 oz × 4
4 hrs= 3 lbs or 48 oz

A rectangular garden is 5 ft longer than it is wide. Its area is 4550 ft. What are its dimensions?
Step-by-step explanation:
Area= lxb
L = 5+d
area= d(5+d)
4550=d²+5d
d²+5d-4550=0
d2+5d−4550=0
(d−65)(d+70)=0
d−65=0 or d+70=0
d=65 or d=−70
dimensions= 65, 70

Write an equation of the line that passes through (−2,3) and (0,8).
An equation is y=
.
Answer:
Step-by-step explanation:
y = mx + b
b is the y intercept and occurs where x = 0. One of our select points has an x value of 0, therefore b = 8
m is the slope and is found as the change in y over the change in x
m = Δy/Δx = (8 - 3) / (0 - (-2)) = 5/2
y = 5x/2 + 8

Find AC. FIND X USING THE PICTURE. BELOW. WILL MARK BRANLIEST FOR FIRST ONE TO ANSWER
Answer:
AC ≈ 50.5
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan29° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{28}{x}[/tex] ( multiply both sides by x )
x × tan29° = 28 ( divide both sides by tan29° )
x = [tex]\frac{28}{tan29}[/tex] ≈ 50.5 ( to the nearest tenth )
Answer:
50.5
Step-by-step explanation:
In the right triangle, focus on angle A. The side marked 28 is the opposite side, and the side marked x is the adjacent side. The trigonometric ratio that uses those two side is the tangent ratio.
tangent = (opposite) / (adjacent)
[tex]\tan{29^\circ}=\frac{28}{x}[/tex]
Multiply both sides by x.
[tex]x\cdot \tan{29^\circ}=28[/tex]
Divide by tan 29 degrees.
[tex]x=\frac{28}{\tan{29^\circ}}[/tex]
Use a calculator (in degree mode!) to approximate x.
[tex]x \approx 50.5[/tex]

O A. 20
O B. 12.8
O C. 500
O D. 128
Answer:
A. 20
Step-by-step explanation:
1. To solve this problem, instead of doing 80/100 times 16, we can do 100/80 times 16 (inverse of percentage, basically).
[tex]\frac{100}{80} *16[/tex] [tex]\frac{5}{4} *16[/tex] [tex]\frac{80}{4}[/tex] [tex]20[/tex]Therefore, the answer is A. 20.

Step-by-step explanation:
This is an isosceles triangle because in an isosceles triangle angles opposite to each of the equal sides must also be equal. Since the diagram shows 2 equal angles we can say its isosceles.
So 3(x+2) = 24
8= x+2
x = 6
Answer:
x = 6
Step-by-step explanation:
The triangle given is an isosceles triangle.
Which means, the two sides and the two angles will be the same.
One of the sides is 24.
The other is 3 ( x + 2 )
Hence, we will get this equation.
24 = 3 ( x + 2 )
24 = 3x + 6
24 - 6 = 3x
18 = 3x
6 = x
Thus, x = 6.

The teacher has 10 pizzas. She can give each child 1/8 of a pizza. How many students will get a slice.
Answer:
80
Step-by-step explanation:
1 pizza has 8 [tex]\frac{1}{8}[/tex]ths. 10 pizzas have 10 × 8 = 80 1/8ths. So 80.
Answer:
80 because if one student gets 1/8 that means 8 students get one slice out of the pizza multiply 8 by 10 and it equals 80
